+===============================
+ Qualcomm Cloud AI 100 (AIC100)
+===============================
+
+Overview
+========
+
+The Qualcomm Cloud AI 100/AIC100 family of products (including SA9000P - part of
+Snapdragon Ride) are PCIe adapter cards which contain a dedicated SoC ASIC for
+the purpose of efficiently running Artificial Intelligence (AI) Deep Learning
+inference workloads. They are AI accelerators.
+
+The PCIe interface of AIC100 is capable of PCIe Gen4 speeds over eight lanes
+(x8). An individual SoC on a card can have up to 16 NSPs for running workloads.
+Each SoC has an A53 management CPU. On card, there can be up to 32 GB of DDR.
+
+Multiple AIC100 cards can be hosted in a single system to scale overall
+performance. AIC100 cards are multi-user capable and able to execute workloads
+from multiple users in a concurrent manner.
+
+Hardware Description
+====================
+
+An AIC100 card consists of an AIC100 SoC, on-card DDR, and a set of misc
+peripherals (PMICs, etc).
+
+An AIC100 card can either be a PCIe HHHL form factor (a traditional PCIe card),
+or a Dual M.2 card. Both use PCIe to connect to the host system.
+
+As a PCIe endpoint/adapter, AIC100 uses the standard VendorID(VID)/
+DeviceID(DID) combination to uniquely identify itself to the host. AIC100
+uses the standard Qualcomm VID (0x17cb). All AIC100 SKUs use the same
+AIC100 DID (0xa100).
+
+AIC100 does not implement FLR (function level reset).
+
+AIC100 implements MSI but does not implement MSI-X. AIC100 requires 17 MSIs to
+operate (1 for MHI, 16 for the DMA Bridge).
+
+As a PCIe device, AIC100 utilizes BARs to provide host interfaces to the device
+hardware. AIC100 provides 3, 64-bit BARs.
+
+* The first BAR is 4K in size, and exposes the MHI interface to the host.
+
+* The second BAR is 2M in size, and exposes the DMA Bridge interface to the
+  host.
+
+* The third BAR is variable in size based on an individual AIC100's
+  configuration, but defaults to 64K. This BAR currently has no purpose.
+
+From the host perspective, AIC100 has several key hardware components -
+
+* MHI (Modem Host Interface)
+* QSM (QAIC Service Manager)
+* NSPs (Neural Signal Processor)
+* DMA Bridge
+* DDR
+
+MHI
+---
+
+AIC100 has one MHI interface over PCIe. MHI itself is documented at
+Documentation/mhi/index.rst MHI is the mechanism the host uses to communicate
+with the QSM. Except for workload data via the DMA Bridge, all interaction with
+the device occurs via MHI.
+
+QSM
+---
+
+QAIC Service Manager. This is an ARM A53 CPU that runs the primary
+firmware of the card and performs on-card management tasks. It also
+communicates with the host via MHI. Each AIC100 has one of
+these.
+
+NSP
+---
+
+Neural Signal Processor. Each AIC100 has up to 16 of these. These are
+the processors that run the workloads on AIC100. Each NSP is a Qualcomm Hexagon
+(Q6) DSP with HVX and HMX. Each NSP can only run one workload at a time, but
+multiple NSPs may be assigned to a single workload. Since each NSP can only run
+one workload, AIC100 is limited to 16 concurrent workloads. Workload
+"scheduling" is under the purview of the host. AIC100 does not automatically
+timeslice.
+
+DMA Bridge
+----------
+
+The DMA Bridge is custom DMA engine that manages the flow of data
+in and out of workloads. AIC100 has one of these. The DMA Bridge has 16
+channels, each consisting of a set of request/response FIFOs. Each active
+workload is assigned a single DMA Bridge channel. The DMA Bridge exposes
+hardware registers to manage the FIFOs (head/tail pointers), but requires host
+memory to store the FIFOs.
+
+DDR
+---
+
+AIC100 has on-card DDR. In total, an AIC100 can have up to 32 GB of DDR.
+This DDR is used to store workloads, data for the workloads, and is used by the
+QSM for managing the device. NSPs are granted access to sections of the DDR by
+the QSM. The host does not have direct access to the DDR, and must make
+requests to the QSM to transfer data to the DDR.
+
+High-level Use Flow
+===================
+
+AIC100 is a multi-user, programmable accelerator typically used for running
+neural networks in inferencing mode to efficiently perform AI operations.
+AIC100 is not intended for training neural networks. AIC100 can be utilized
+for generic compute workloads.
+
+Assuming a user wants to utilize AIC100, they would follow these steps:
+
+1. Compile the workload into an ELF targeting the NSP(s)
+2. Make requests to the QSM to load the workload and related artifacts into the
+   device DDR
+3. Make a request to the QSM to activate the workload onto a set of idle NSPs
+4. Make requests to the DMA Bridge to send input data to the workload to be
+   processed, and other requests to receive processed output data from the
+   workload.
+5. Once the workload is no longer required, make a request to the QSM to
+   deactivate the workload, thus putting the NSPs back into an idle state.
+6. Once the workload and related artifacts are no longer needed for future
+   sessions, make requests to the QSM to unload the data from DDR. This frees
+   the DDR to be used by other users.
+
+
+Boot Flow
+=========
+
+AIC100 uses a flashless boot flow, derived from Qualcomm MSMs.
+
+When AIC100 is first powered on, it begins executing PBL (Primary Bootloader)
+from ROM. PBL enumerates the PCIe link, and initializes the BHI (Boot Host
+Interface) component of MHI.
+
+Using BHI, the host points PBL to the location of the SBL (Secondary Bootloader)
+image. The PBL pulls the image from the host, validates it, and begins
+execution of SBL.
+
+SBL initializes MHI, and uses MHI to notify the host that the device has entered
+the SBL stage. SBL performs a number of operations:
+
+* SBL initializes the majority of hardware (anything PBL left uninitialized),
+  including DDR.
+* SBL offloads the bootlog to the host.
+* SBL synchronizes timestamps with the host for future logging.
+* SBL uses the Sahara protocol to obtain the runtime firmware images from the
+  host.
+
+Once SBL has obtained and validated the runtime firmware, it brings the NSPs out
+of reset, and jumps into the QSM.
+
+The QSM uses MHI to notify the host that the device has entered the QSM stage
+(AMSS in MHI terms). At this point, the AIC100 device is fully functional, and
+ready to process workloads.

+DMA Bridge
+==========
+
+Overview
+--------
+
+The DMA Bridge is one of the main interfaces to the host from the device
+(the other being MHI). As part of activating a workload to run on NSPs, the QSM
+assigns that network a DMA Bridge channel. A workload's DMA Bridge channel
+(DBC for short) is solely for the use of that workload and is not shared with
+other workloads.
+
+Each DBC is a pair of FIFOs that manage data in and out of the workload. One
+FIFO is the request FIFO. The other FIFO is the response FIFO.
+
+Each DBC contains 4 registers in hardware:
+
+* Request FIFO head pointer (offset 0x0). Read only by the host. Indicates the
+  latest item in the FIFO the device has consumed.
+* Request FIFO tail pointer (offset 0x4). Read/write by the host. Host
+  increments this register to add new items to the FIFO.
+* Response FIFO head pointer (offset 0x8). Read/write by the host. Indicates
+  the latest item in the FIFO the host has consumed.
+* Response FIFO tail pointer (offset 0xc). Read only by the host. Device
+  increments this register to add new items to the FIFO.
+
+The values in each register are indexes in the FIFO. To get the location of the
+FIFO element pointed to by the register: FIFO base address + register * element
+size.
+
+DBC registers are exposed to the host via the second BAR. Each DBC consumes
+4KB of space in the BAR.
+
+The actual FIFOs are backed by host memory. When sending a request to the QSM
+to activate a network, the host must donate memory to be used for the FIFOs.
+Due to internal mapping limitations of the device, a single contiguous chunk of
+memory must be provided per DBC, which hosts both FIFOs. The request FIFO will
+consume the beginning of the memory chunk, and the response FIFO will consume
+the end of the memory chunk.
+
+Request FIFO
+------------
+
+A request FIFO element has the following structure:
+
+.. code-block:: c
+
+  struct request_elem {
+	u16 req_id;
+	u8  seq_id;
+	u8  pcie_dma_cmd;
+	u32 reserved;
+	u64 pcie_dma_source_addr;
+	u64 pcie_dma_dest_addr;
+	u32 pcie_dma_len;
+	u32 reserved;
+	u64 doorbell_addr;
+	u8  doorbell_attr;
+	u8  reserved;
+	u16 reserved;
+	u32 doorbell_data;
+	u32 sem_cmd0;
+	u32 sem_cmd1;
+	u32 sem_cmd2;
+	u32 sem_cmd3;
+  };
+
+Request field descriptions:
+
+req_id
+	request ID. A request FIFO element and a response FIFO element with
+	the same request ID refer to the same command.
+
+seq_id
+	sequence ID within a request. Ignored by the DMA Bridge.
+
+pcie_dma_cmd
+	describes the DMA element of this request.
+
+	* Bit(7) is the force msi flag, which overrides the DMA Bridge MSI logic
+	  and generates a MSI when this request is complete, and QSM
+	  configures the DMA Bridge to look at this bit.
+	* Bits(6:5) are reserved.
+	* Bit(4) is the completion code flag, and indicates that the DMA Bridge
+	  shall generate a response FIFO element when this request is
+	  complete.
+	* Bit(3) indicates if this request is a linked list transfer(0) or a bulk
+	  transfer(1).
+	* Bit(2) is reserved.
+	* Bits(1:0) indicate the type of transfer. No transfer(0), to device(1),
+	  from device(2). Value 3 is illegal.
+
+pcie_dma_source_addr
+	source address for a bulk transfer, or the address of the linked list.
+
+pcie_dma_dest_addr
+	destination address for a bulk transfer.
+
+pcie_dma_len
+	length of the bulk transfer. Note that the size of this field
+	limits transfers to 4G in size.
+
+doorbell_addr
+	address of the doorbell to ring when this request is complete.
+
+doorbell_attr
+	doorbell attributes.
+
+	* Bit(7) indicates if a write to a doorbell is to occur.
+	* Bits(6:2) are reserved.
+	* Bits(1:0) contain the encoding of the doorbell length. 0 is 32-bit,
+	  1 is 16-bit, 2 is 8-bit, 3 is reserved. The doorbell address
+	  must be naturally aligned to the specified length.
+
+doorbell_data
+	data to write to the doorbell. Only the bits corresponding to
+	the doorbell length are valid.
+
+sem_cmdN
+	semaphore command.
+
+	* Bit(31) indicates this semaphore command is enabled.
+	* Bit(30) is the to-device DMA fence. Block this request until all
+	  to-device DMA transfers are complete.
+	* Bit(29) is the from-device DMA fence. Block this request until all
+	  from-device DMA transfers are complete.
+	* Bits(28:27) are reserved.
+	* Bits(26:24) are the semaphore command. 0 is NOP. 1 is init with the
+	  specified value. 2 is increment. 3 is decrement. 4 is wait
+	  until the semaphore is equal to the specified value. 5 is wait
+	  until the semaphore is greater or equal to the specified value.
+	  6 is "P", wait until semaphore is greater than 0, then
+	  decrement by 1. 7 is reserved.
+	* Bit(23) is reserved.
+	* Bit(22) is the semaphore sync. 0 is post sync, which means that the
+	  semaphore operation is done after the DMA transfer. 1 is
+	  presync, which gates the DMA transfer. Only one presync is
+	  allowed per request.
+	* Bit(21) is reserved.
+	* Bits(20:16) is the index of the semaphore to operate on.
+	* Bits(15:12) are reserved.
+	* Bits(11:0) are the semaphore value to use in operations.
+
+Overall, a request is processed in 4 steps:
+
+1. If specified, the presync semaphore condition must be true
+2. If enabled, the DMA transfer occurs
+3. If specified, the postsync semaphore conditions must be true
+4. If enabled, the doorbell is written
+
+By using the semaphores in conjunction with the workload running on the NSPs,
+the data pipeline can be synchronized such that the host can queue multiple
+requests of data for the workload to process, but the DMA Bridge will only copy
+the data into the memory of the workload when the workload is ready to process
+the next input.
+
+Response FIFO
+-------------
+
+Once a request is fully processed, a response FIFO element is generated if
+specified in pcie_dma_cmd. The structure of a response FIFO element:
+
+.. code-block:: c
+
+  struct response_elem {
+	u16 req_id;
+	u16 completion_code;
+  };
+
+req_id
+	matches the req_id of the request that generated this element.
+
+completion_code
+	status of this request. 0 is success. Non-zero is an error.
+
+The DMA Bridge will generate a MSI to the host as a reaction to activity in the
+response FIFO of a DBC. The DMA Bridge hardware has an IRQ storm mitigation
+algorithm, where it will only generate a MSI when the response FIFO transitions
+from empty to non-empty (unless force MSI is enabled and triggered). In
+response to this MSI, the host is expected to drain the response FIFO, and must
+take care to handle any race conditions between draining the FIFO, and the
+device inserting elements into the FIFO.
+
+Neural Network Control (NNC) Protocol
+=====================================
+
+The NNC protocol is how the host makes requests to the QSM to manage workloads.
+It uses the QAIC_CONTROL MHI channel.
+
+Each NNC request is packaged into a message. Each message is a series of
+transactions. A passthrough type transaction can contain elements known as
+commands.
+
+QSM requires NNC messages be little endian encoded and the fields be naturally
+aligned. Since there are 64-bit elements in some NNC messages, 64-bit alignment
+must be maintained.
+
+A message contains a header and then a series of transactions. A message may be
+at most 4K in size from QSM to the host. From the host to the QSM, a message
+can be at most 64K (maximum size of a single MHI packet), but there is a
+continuation feature where message N+1 can be marked as a continuation of
+message N. This is used for exceedingly large DMA xfer transactions.
+
+Transaction descriptions
+------------------------
+
+passthrough
+	Allows userspace to send an opaque payload directly to the QSM.
+	This is used for NNC commands. Userspace is responsible for managing
+	the QSM message requirements in the payload.
+
+dma_xfer
+	DMA transfer. Describes an object that the QSM should DMA into the
+	device via address and size tuples.
+
+activate
+	Activate a workload onto NSPs. The host must provide memory to be
+	used by the DBC.
+
+deactivate
+	Deactivate an active workload and return the NSPs to idle.
+
+status
+	Query the QSM about it's NNC implementation. Returns the NNC version,
+	and if CRC is used.
+
+terminate
+	Release a user's resources.
+
+dma_xfer_cont
+	Continuation of a previous DMA transfer. If a DMA transfer
+	cannot be specified in a single message (highly fragmented), this
+	transaction can be used to specify more ranges.
+
+validate_partition
+	Query to QSM to determine if a partition identifier is valid.
+
+Each message is tagged with a user id, and a partition id. The user id allows
+QSM to track resources, and release them when the user goes away (eg the process
+crashes). A partition id identifies the resource partition that QSM manages,
+which this message applies to.
+
+Messages may have CRCs. Messages should have CRCs applied until the QSM
+reports via the status transaction that CRCs are not needed. The QSM on the
+SA9000P requires CRCs for black channel safing.
+
+Subsystem Restart (SSR)
+=======================
+
+SSR is the concept of limiting the impact of an error. An AIC100 device may
+have multiple users, each with their own workload running. If the workload of
+one user crashes, the fallout of that should be limited to that workload and not
+impact other workloads. SSR accomplishes this.
+
+If a particular workload crashes, QSM notifies the host via the QAIC_SSR MHI
+channel. This notification identifies the workload by it's assigned DBC. A
+multi-stage recovery process is then used to cleanup both sides, and get the
+DBC/NSPs into a working state.
+
+When SSR occurs, any state in the workload is lost. Any inputs that were in
+process, or queued by not yet serviced, are lost. The loaded artifacts will
+remain in on-card DDR, but the host will need to re-activate the workload if
+it desires to recover the workload.
+
+Reliability, Accessibility, Serviceability (RAS)
+================================================
+
+AIC100 is expected to be deployed in server systems where RAS ideology is
+applied. Simply put, RAS is the concept of detecting, classifying, and
+reporting errors. While PCIe has AER (Advanced Error Reporting) which factors
+into RAS, AER does not allow for a device to report details about internal
+errors. Therefore, AIC100 implements a custom RAS mechanism. When a RAS event
+occurs, QSM will report the event with appropriate details via the QAIC_STATUS
+MHI channel. A sysadmin may determine that a particular device needs
+additional service based on RAS reports.
+
+Telemetry
+=========
+
+QSM has the ability to report various physical attributes of the device, and in
+some cases, to allow the host to control them. Examples include thermal limits,
+thermal readings, and power readings. These items are communicated via the
+QAIC_TELEMETRY MHI channel.

+=============
+ QAIC driver
+=============
+
+The QAIC driver is the Kernel Mode Driver (KMD) for the AIC100 family of AI
+accelerator products.
+
+Interrupts
+==========
+
+While the AIC100 DMA Bridge hardware implements an IRQ storm mitigation
+mechanism, it is still possible for an IRQ storm to occur. A storm can happen
+if the workload is particularly quick, and the host is responsive. If the host
+can drain the response FIFO as quickly as the device can insert elements into
+it, then the device will frequently transition the response FIFO from empty to
+non-empty and generate MSIs at a rate equivalent to the speed of the
+workload's ability to process inputs. The lprnet (license plate reader network)
+workload is known to trigger this condition, and can generate in excess of 100k
+MSIs per second. It has been observed that most systems cannot tolerate this
+for long, and will crash due to some form of watchdog due to the overhead of
+the interrupt controller interrupting the host CPU.
+
+To mitigate this issue, the QAIC driver implements specific IRQ handling. When
+QAIC receives an IRQ, it disables that line. This prevents the interrupt
+controller from interrupting the CPU. Then AIC drains the FIFO. Once the FIFO
+is drained, QAIC implements a "last chance" polling algorithm where QAIC will
+sleep for a time to see if the workload will generate more activity. The IRQ
+line remains disabled during this time. If no activity is detected, QAIC exits
+polling mode and reenables the IRQ line.
+
+This mitigation in QAIC is very effective. The same lprnet usecase that
+generates 100k IRQs per second (per /proc/interrupts) is reduced to roughly 64
+IRQs over 5 minutes while keeping the host system stable, and having the same
+workload throughput performance (within run to run noise variation).
+
+
+Neural Network Control (NNC) Protocol
+=====================================
+
+The implementation of NNC is split between the KMD (QAIC) and UMD. In general
+QAIC understands how to encode/decode NNC wire protocol, and elements of the
+protocol which require kernel space knowledge to process (for example, mapping
+host memory to device IOVAs). QAIC understands the structure of a message, and
+all of the transactions. QAIC does not understand commands (the payload of a
+passthrough transaction).
+
+QAIC handles and enforces the required little endianness and 64-bit alignment,
+to the degree that it can. Since QAIC does not know the contents of a
+passthrough transaction, it relies on the UMD to satisfy the requirements.
+
+The terminate transaction is of particular use to QAIC. QAIC is not aware of
+the resources that are loaded onto a device since the majority of that activity
+occurs within NNC commands. As a result, QAIC does not have the means to
+roll back userspace activity. To ensure that a userspace client's resources
+are fully released in the case of a process crash, or a bug, QAIC uses the
+terminate command to let QSM know when a user has gone away, and the resources
+can be released.
+
+QSM can report a version number of the NNC protocol it supports. This is in the
+form of a Major number and a Minor number.
+
+Major number updates indicate changes to the NNC protocol which impact the
+message format, or transactions (impacts QAIC).
+
+Minor number updates indicate changes to the NNC protocol which impact the
+commands (does not impact QAIC).
+
+uAPI
+====
+
+QAIC defines a number of driver specific IOCTLs as part of the userspace API.
+This section describes those APIs.
+
+DRM_IOCTL_QAIC_MANAGE
+  This IOCTL allows userspace to send a NNC request to the QSM. The call will
+  block until a response is received, or the request has timed out.
+
+DRM_IOCTL_QAIC_CREATE_BO
+  This IOCTL allows userspace to allocate a buffer object (BO) which can send
+  or receive data from a workload. The call will return a GEM handle that
+  represents the allocated buffer. The BO is not usable until it has been
+  sliced (see DRM_IOCTL_QAIC_ATTACH_SLICE_BO).
+
+DRM_IOCTL_QAIC_MMAP_BO
+  This IOCTL allows userspace to prepare an allocated BO to be mmap'd into the
+  userspace process.
+
+DRM_IOCTL_QAIC_ATTACH_SLICE_BO
+  This IOCTL allows userspace to slice a BO in preparation for sending the BO
+  to the device. Slicing is the operation of describing what portions of a BO
+  get sent where to a workload. This requires a set of DMA transfers for the
+  DMA Bridge, and as such, locks the BO to a specific DBC.
+
+DRM_IOCTL_QAIC_EXECUTE_BO
+  This IOCTL allows userspace to submit a set of sliced BOs to the device. The
+  call is non-blocking. Success only indicates that the BOs have been queued
+  to the device, but does not guarantee they have been executed.
+
+DRM_IOCTL_QAIC_PARTIAL_EXECUTE_BO
+  This IOCTL operates like DRM_IOCTL_QAIC_EXECUTE_BO, but it allows userspace
+  to shrink the BOs sent to the device for this specific call. If a BO
+  typically has N inputs, but only a subset of those is available, this IOCTL
+  allows userspace to indicate that only the first M bytes of the BO should be
+  sent to the device to minimize data transfer overhead. This IOCTL dynamically
+  recomputes the slicing, and therefore has some processing overhead before the
+  BOs can be queued to the device.
+
+DRM_IOCTL_QAIC_WAIT_BO
+  This IOCTL allows userspace to determine when a particular BO has been
+  processed by the device. The call will block until either the BO has been
+  processed and can be re-queued to the device, or a timeout occurs.
+
+DRM_IOCTL_QAIC_PERF_STATS_BO
+  This IOCTL allows userspace to collect performance statistics on the most
+  recent execution of a BO. This allows userspace to construct an end to end
+  timeline of the BO processing for a performance analysis.
+
+DRM_IOCTL_QAIC_PART_DEV
+  This IOCTL allows userspace to request a duplicate "shadow device". This extra
+  accelN device is associated with a specific partition of resources on the
+  AIC100 device and can be used for limiting a process to some subset of
+  resources.
+
+Userspace Client Isolation
+==========================
+
+AIC100 supports multiple clients. Multiple DBCs can be consumed by a single
+client, and multiple clients can each consume one or more DBCs. Workloads
+may contain sensitive information therefore only the client that owns the
+workload should be allowed to interface with the DBC.
+
+Clients are identified by the instance associated with their open(). A client
+may only use memory they allocate, and DBCs that are assigned to their
+workloads. Attempts to access resources assigned to other clients will be
+rejected.
+
+Module parameters
+=================
+
+QAIC supports the following module parameters:
+
+**datapath_polling (bool)**
+
+Configures QAIC to use a polling thread for datapath events instead of relying
+on the device interrupts. Useful for platforms with broken multiMSI. Must be
+set at QAIC driver initialization. Default is 0 (off).
+
+**mhi_timeout_ms (unsigned int)**
+
+Sets the timeout value for MHI operations in milliseconds (ms). Must be set
+at the time the driver detects a device. Default is 2000 (2 seconds).
+
+**control_resp_timeout_s (unsigned int)**
+
+Sets the timeout value for QSM responses to NNC messages in seconds (s). Must
+be set at the time the driver is sending a request to QSM. Default is 60 (one
+minute).
+
+**wait_exec_default_timeout_ms (unsigned int)**
+
+Sets the default timeout for the wait_exec ioctl in milliseconds (ms). Must be
+set prior to the waic_exec ioctl call. A value specified in the ioctl call
+overrides this for that call. Default is 5000 (5 seconds).
+
+**datapath_poll_interval_us (unsigned int)**
+
+Sets the polling interval in microseconds (us) when datapath polling is active.
+Takes effect at the next polling interval. Default is 100 (100 us).

 This dts change will enable two cec GPIO devices: I typically use one to
 send/receive CEC commands and the other to monitor. If you monitor using
 an unconfigured CEC adapter then it will use GPIO interrupts which makes
 monitoring very accurate.
 
+If you just want to monitor traffic, then a single instance is sufficient.
+The minimum configuration is one HDMI female-female passthrough connector
+and two female-female breadboard wires: one for connecting the HDMI ground
+pin to a ground pin on the Raspberry Pi, and the other to connect the HDMI
+CEC pin to GPIO 6 on the Raspberry Pi.

 The documentation on how to use the error injection is here: :ref:`cec_pin_error_inj`.
 
 ``cec-ctl --monitor-pin`` will do low-level CEC bus sniffing and analysis.

+
+This guide explains how to swiftly build Linux kernels that are ideal for
+testing purposes, but perfectly fine for day-to-day use, too.
+
+The essence of the process (aka 'TL;DR')
+========================================
+
+*[If you are new to compiling Linux, ignore this TLDR and head over to the next
+section below: it contains a step-by-step guide, which is more detailed, but
+still brief and easy to follow; that guide and its accompanying reference
+section also mention alternatives, pitfalls, and additional aspects, all of
+which might be relevant for you.]*
+
+If your system uses techniques like Secure Boot, prepare it to permit starting
+self-compiled Linux kernels; install compilers and everything else needed for
+building Linux; make sure to have 12 Gigabyte free space in your home directory.
+Now run the following commands to download fresh Linux mainline sources, which
+you then use to configure, build and install your own kernel::

+
+Step-by-step guide
+==================
+
+Compiling your own Linux kernel is easy in principle. There are various ways to
+do it. Which of them actually work and is the best depends on the circumstances.
+
+This guide describes a way perfectly suited for those who want to quickly
+install Linux from sources without being bothered by complicated details; the
+goal is to cover everything typically needed on mainstream Linux distributions
+running on commodity PC or server hardware.
+
+The described approach is great for testing purposes, for example to try a
+proposed fix or to check if a problem was already fixed in the latest codebase.
+Nonetheless, kernels built this way are also totally fine for day-to-day use
+while at the same time being easy to keep up to date.
+
+The following steps describe the important aspects of the process; a
+comprehensive reference section later explains each of them in more detail. It
+sometimes also describes alternative approaches, pitfalls, as well as errors
+that might occur at a particular point -- and how to then get things rolling
+again.
+
+..
+   Note: if you see this note, you are reading the text's source file. You
+   might want to switch to a rendered version, as it makes it a lot easier to
+   quickly look something up in the reference section and afterwards jump back
+   to where you left off. Find a the latest rendered version here:

+.. _backup_sbs:
+
+ * Create a fresh backup and put system repair and restore tools at hand, just
+   to be prepared for the unlikely case of something going sideways.
+
+   [:ref:`details<backup>`]
+
+.. _secureboot_sbs:
+
+ * On platforms with 'Secure Boot' or similar techniques, prepare everything to
+   ensure the system will permit your self-compiled kernel to boot later. The
+   quickest and easiest way to achieve this on commodity x86 systems is to
+   disable such techniques in the BIOS setup utility; alternatively, remove
+   their restrictions through a process initiated by
+   ``mokutil --disable-validation``.
+
+   [:ref:`details<secureboot>`]
+
+.. _buildrequires_sbs:
+
+ * Install all software required to build a Linux kernel. Often you will need:
+   'bc', 'binutils' ('ld' et al.), 'bison', 'flex', 'gcc', 'git', 'openssl',
+   'pahole', 'perl', and the development headers for 'libelf' and 'openssl'. The
+   reference section shows how to quickly install those on various popular Linux
+   distributions.
+
+   [:ref:`details<buildrequires>`]
+
+.. _diskspace_sbs:
+
+ * Ensure to have enough free space for building and installing Linux. For the
+   latter 150 Megabyte in /lib/ and 100 in /boot/ are a safe bet. For storing
+   sources and build artifacts 12 Gigabyte in your home directory should
+   typically suffice. If you have less available, be sure to check the reference
+   section for the step that explains adjusting your kernels build
+   configuration: it mentions a trick that reduce the amount of required space
+   in /home/ to around 4 Gigabyte.
+
+   [:ref:`details<diskspace>`]
+
+.. _sources_sbs:
+
+ * Retrieve the sources of the Linux version you intend to build; then change
+   into the directory holding them, as all further commands in this guide are
+   meant to be executed from there.
+
+   *[Note: the following paragraphs describe how to retrieve the sources by
+   partially cloning the Linux stable git repository. This is called a shallow
+   clone. The reference section explains two alternatives:* :ref:`packaged
+   archives<sources_archive>` *and* :ref:`a full git clone<sources_full>` *;
+   prefer the latter, if downloading a lot of data does not bother you, as that
+   will avoid some* :ref:`peculiar characteristics of shallow clones the
+   reference section explains<sources_shallow>` *.]*
+
+   First, execute the following command to retrieve a fresh mainline codebase::
+
+     git clone --no-checkout --depth 1 -b master \
+       https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git ~/linux/
+     cd ~/linux/
+
+   If you want to access recent mainline releases and pre-releases, deepen you
+   clone's history to the oldest mainline version you are interested in::
+
+     git fetch --shallow-exclude=v6.0 origin
+
+   In case you want to access a stable/longterm release (say v6.1.5), simply add
+   the branch holding that series; afterwards fetch the history at least up to
+   the mainline version that started the series (v6.1)::
+
+     git remote set-branches --add origin linux-6.1.y
+     git fetch --shallow-exclude=v6.0 origin
+
+   Now checkout the code you are interested in. If you just performed the
+   initial clone, you will be able to check out a fresh mainline codebase, which
+   is ideal for checking whether developers already fixed an issue::
+
+      git checkout --detach origin/master
+
+   If you deepened your clone, you instead of ``origin/master`` can specify the
+   version you deepened to (``v6.0`` above); later releases like ``v6.1`` and
+   pre-release like ``v6.2-rc1`` will work, too. Stable or longterm versions
+   like ``v6.1.5`` work just the same, if you added the appropriate
+   stable/longterm branch as described.
+
+   [:ref:`details<sources>`]
+
+.. _patching_sbs:
+
+ * In case you want to apply a kernel patch, do so now. Often a command like
+   this will do the trick::
+
+     patch -p1 < ../proposed-fix.patch
+
+   If the ``-p1`` is actually needed, depends on how the patch was created; in
+   case it does not apply thus try without it.
+
+   If you cloned the sources with git and anything goes sideways, run ``git
+   reset --hard`` to undo any changes to the sources.
+
+   [:ref:`details<patching>`]
+
+.. _tagging_sbs:
+
+ * If you patched your kernel or have one of the same version installed already,
+   better add a unique tag to the one you are about to build::
+
+     echo "-proposed_fix" > localversion
+
+   Running ``uname -r`` under your kernel later will then print something like
+   '6.1-rc4-proposed_fix'.
+
+   [:ref:`details<tagging>`]
+
+ .. _configuration_sbs:
+
+ * Create the build configuration for your kernel based on an existing
+   configuration.
+
+   If you already prepared such a '.config' file yourself, copy it to
+   ~/linux/ and run ``make olddefconfig``.
+
+   Use the same command, if your distribution or somebody else already tailored
+   your running kernel to your or your hardware's needs: the make target
+   'olddefconfig' will then try to use that kernel's .config as base.
+
+   Using this make target is fine for everybody else, too -- but you often can
+   save a lot of time by using this command instead::
+
+     yes "" | make localmodconfig
+
+   This will try to pick your distribution's kernel as base, but then disable
+   modules for any features apparently superfluous for your setup. This will
+   reduce the compile time enormously, especially if you are running an
+   universal kernel from a commodity Linux distribution.
+
+   There is a catch: 'localmodconfig' is likely to disable kernel features you
+   did not use since you booted your Linux -- like drivers for currently
+   disconnected peripherals or a virtualization software not haven't used yet.
+   You can reduce or nearly eliminate that risk with tricks the reference
+   section outlines; but when building a kernel just for quick testing purposes
+   it is often negligible if such features are missing. But you should keep that
+   aspect in mind when using a kernel built with this make target, as it might
+   be the reason why something you only use occasionally stopped working.
+
+   [:ref:`details<configuration>`]
+
+.. _configmods_sbs:
+
+ * Check if you might want to or have to adjust some kernel configuration
+   options:
+
+  * Evaluate how you want to handle debug symbols. Enable them, if you later
+    might need to decode a stack trace found for example in a 'panic', 'Oops',
+    'warning', or 'BUG'; on the other hand disable them, if you are short on
+    storage space or prefer a smaller kernel binary. See the reference section
+    for details on how to do either. If neither applies, it will likely be fine
+    to simply not bother with this. [:ref:`details<configmods_debugsymbols>`]
+
+  * Are you running Debian? Then to avoid known problems by performing
+    additional adjustments explained in the reference section.
+    [:ref:`details<configmods_distros>`].
+
+  * If you want to influence the other aspects of the configuration, do so now
+    by using make targets like 'menuconfig' or 'xconfig'.
+    [:ref:`details<configmods_individual>`].
+
+.. _build_sbs:
+
+ * Build the image and the modules of your kernel::
+
+     make -j $(nproc --all)
+
+   If you want your kernel packaged up as deb, rpm, or tar file, see the
+   reference section for alternatives.
+
+   [:ref:`details<build>`]
+
+.. _install_sbs:
+
+ * Now install your kernel::
+
+     command -v installkernel && sudo make modules_install install
+
+   Often all left for you to do afterwards is a ``reboot``, as many commodity
+   Linux distributions will then create an initramfs (also known as initrd) and
+   an entry for your kernel in your bootloader's configuration; but on some
+   distributions you have to take care of these two steps manually for reasons
+   the reference section explains.
+
+   On a few distributions like Arch Linux and its derivatives the above command
+   does nothing at all; in that case you have to manually install your kernel,
+   as outlined in the reference section.
+
+   If you are running a immutable Linux distribution, check its documentation
+   and the web to find out how to install your own kernel there.
+
+   [:ref:`details<install>`]
+
+.. _another_sbs:
+
+ * To later build another kernel you need similar steps, but sometimes slightly
+   different commands.
+
+   First, switch back into the sources tree::
+
+      cd ~/linux/
+
+   In case you want to build a version from a stable/longterm series you have
+   not used yet (say 6.2.y), tell git to track it::
+
+      git remote set-branches --add origin linux-6.2.y
+
+   Now fetch the latest upstream changes; you again need to specify the earliest
+   version you care about, as git otherwise might retrieve the entire commit
+   history::
+
+     git fetch --shallow-exclude=v6.0 origin
+
+   Now switch to the version you are interested in -- but be aware the command
+   used here will discard any modifications you performed, as they would
+   conflict with the sources you want to checkout::
+
+     git checkout --force --detach origin/master
+
+   At this point you might want to patch the sources again or set/modify a build
+   tag, as explained earlier. Afterwards adjust the build configuration to the
+   new codebase using olddefconfig, which will now adjust the configuration file
+   you prepared earlier using localmodconfig  (~/linux/.config) for your next
+   kernel::
+
+     # reminder: if you want to apply patches, do it at this point
+     # reminder: you might want to update your build tag at this point
+     make olddefconfig
+
+   Now build your kernel::
+
+     make -j $(nproc --all)
+
+   Afterwards install the kernel as outlined above::
+
+     command -v installkernel && sudo make modules_install install
+
+   [:ref:`details<another>`]
+
+.. _uninstall_sbs:
+
+ * Your kernel is easy to remove later, as its parts are only stored in two
+   places and clearly identifiable by the kernel's release name. Just ensure to
+   not delete the kernel you are running, as that might render your system
+   unbootable.
+
+   Start by deleting the directory holding your kernel's modules, which is named
+   after its release name -- '6.0.1-foobar' in the following example::
+
+     sudo rm -rf /lib/modules/6.0.1-foobar
+
+   Now try the following command, which on some distributions will delete all
+   other kernel files installed while also removing the kernel's entry from the
+   bootloader configuration::
+
+     command -v kernel-install && sudo kernel-install -v remove 6.0.1-foobar
+
+   If that command does not output anything or fails, see the reference section;
+   do the same if any files named '*6.0.1-foobar*' remain in /boot/.
+
+   [:ref:`details<uninstall>`]
+
+.. _submit_improvements:
+
+Did you run into trouble following any of the above steps that is not cleared up
+by the reference section below? Or do you have ideas how to improve the text?
+Then please take a moment of your time and let the maintainer of this document
+know by email (Thorsten Leemhuis <linux@leemhuis.info>), ideally while CCing the

+Reference section for the step-by-step guide
+============================================
+
+This section holds additional information for each of the steps in the above
+guide.
+
+.. _backup:
+
+Prepare for emergencies
+-----------------------
+
+   *Create a fresh backup and put system repair and restore tools at hand*
+   [:ref:`... <backup_sbs>`]
+
+Remember, you are dealing with computers, which sometimes do unexpected things
+-- especially if you fiddle with crucial parts like the kernel of an operating
+system. That's what you are about to do in this process. Hence, better prepare
+for something going sideways, even if that should not happen.
+
+[:ref:`back to step-by-step guide <backup_sbs>`]
+
+.. _secureboot:
+
+Dealing with techniques like Secure Boot
+----------------------------------------
+
+   *On platforms with 'Secure Boot' or similar techniques, prepare everything to
+   ensure the system will permit your self-compiled kernel to boot later.*
+   [:ref:`... <secureboot_sbs>`]
+
+Many modern systems allow only certain operating systems to start; they thus by
+default will reject booting self-compiled kernels.
+
+You ideally deal with this by making your platform trust your self-built kernels
+with the help of a certificate and signing. How to do that is not described
+here, as it requires various steps that would take the text too far away from
+its purpose; 'Documentation/admin-guide/module-signing.rst' and various web
+sides already explain this in more detail.
+
+Temporarily disabling solutions like Secure Boot is another way to make your own
+Linux boot. On commodity x86 systems it is possible to do this in the BIOS Setup
+utility; the steps to do so are not described here, as they greatly vary between
+machines.
+
+On mainstream x86 Linux distributions there is a third and universal option:
+disable all Secure Boot restrictions for your Linux environment. You can
+initiate this process by running ``mokutil --disable-validation``; this will
+tell you to create a one-time password, which is safe to write down. Now
+restart; right after your BIOS performed all self-tests the bootloader Shim will
+show a blue box with a message 'Press any key to perform MOK management'. Hit
+some key before the countdown exposes. This will open a menu and choose 'Change
+Secure Boot state' there. Shim's 'MokManager' will now ask you to enter three
+randomly chosen characters from the one-time password specified earlier. Once
+you provided them, confirm that you really want to disable the validation.
+Afterwards, permit MokManager to reboot the machine.
+
+[:ref:`back to step-by-step guide <secureboot_sbs>`]
+
+.. _buildrequires:
+
+Install build requirements
+--------------------------
+
+   *Install all software required to build a Linux kernel.*
+   [:ref:`...<buildrequires_sbs>`]
+
+The kernel is pretty stand-alone, but besides tools like the compiler you will
+sometimes need a few libraries to build one. How to install everything needed
+depends on your Linux distribution and the configuration of the kernel you are
+about to build.
+
+Here are a few examples what you typically need on some mainstream
+distributions:
+
+ * Debian, Ubuntu, and derivatives::
+
+     sudo apt install bc binutils bison dwarves flex gcc git make openssl \
+       pahole perl-base libssl-dev libelf-dev
+
+ * Fedora and derivatives::
+
+     sudo dnf install binutils /usr/include/{libelf.h,openssl/pkcs7.h} \
+       /usr/bin/{bc,bison,flex,gcc,git,openssl,make,perl,pahole}
+
+ * openSUSE and derivatives::
+
+     sudo zypper install bc binutils bison dwarves flex gcc git make perl-base \
+       openssl openssl-devel libelf-dev
+
+In case you wonder why these lists include openssl and its development headers:
+they are needed for the Secure Boot support, which many distributions enable in
+their kernel configuration for x86 machines.
+
+Sometimes you will need tools for compression formats like bzip2, gzip, lz4,
+lzma, lzo, xz, or zstd as well.
+
+You might need additional libraries and their development headers in case you
+perform tasks not covered in this guide. For example, zlib will be needed when
+building kernel tools from the tools/ directory; adjusting the build
+configuration with make targets like 'menuconfig' or 'xconfig' will require
+development headers for ncurses or Qt5.

+Space requirements
+------------------
+
+   *Ensure to have enough free space for building and installing Linux.*
+   [:ref:`... <diskspace_sbs>`]
+
+The numbers mentioned are rough estimates with a big extra charge to be on the
+safe side, so often you will need less.
+
+If you have space constraints, remember to read the reference section when you
+reach the :ref:`section about configuration adjustments' <configmods>`, as

+
+.. _sources:
+
+Download the sources
+--------------------
+
+  *Retrieve the sources of the Linux version you intend to build.*
+  [:ref:`...<sources_sbs>`]
+
+The step-by-step guide outlines how to retrieve Linux' sources using a shallow
+git clone. There is :ref:`more to tell about this method<sources_shallow>` and
+two alternate ways worth describing: :ref:`packaged archives<sources_archive>`
+and :ref:`a full git clone<sources_full>`. And the aspects ':ref:`wouldn't it
+be wiser to use a proper pre-release than the latest mainline code
+<sources_snapshot>`' and ':ref:`how to get an even fresher mainline codebase
+<sources_fresher>`' need elaboration, too.
+
+Note, to keep things simple the commands used in this guide store the build
+artifacts in the source tree. If you prefer to separate them, simply add
+something like ``O=~/linux-builddir/`` to all make calls; also adjust the path
+in all commands that add files or modify any generated (like your '.config').
+
+[:ref:`back to step-by-step guide <sources_sbs>`]
+
+.. _sources_shallow:
+
+Noteworthy characteristics of shallow clones
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The step-by-step guide uses a shallow clone, as it is the best solution for most
+of this document's target audience. There are a few aspects of this approach
+worth mentioning:
+
+ * This document in most places uses ``git fetch`` with ``--shallow-exclude=``
+   to specify the earliest version you care about (or to be precise: its git
+   tag). You alternatively can use the parameter ``--shallow-since=`` to specify
+   an absolute (say ``'2023-07-15'``) or relative (``'12 months'``) date to
+   define the depth of the history you want to download. As a second
+   alternative, you can also specify a certain depth explicitly with a parameter
+   like ``--depth=1``, unless you add branches for stable/longterm kernels.
+
+ * When running ``git fetch``, remember to always specify the oldest version,
+   the time you care about, or an explicit depth as shown in the step-by-step
+   guide. Otherwise you will risk downloading nearly the entire git history,
+   which will consume quite a bit of time and bandwidth while also stressing the
+   servers.
+
+   Note, you do not have to use the same version or date all the time. But when
+   you change it over time, git will deepen or flatten the history to the
+   specified point. That allows you to retrieve versions you initially thought
+   you did not need -- or it will discard the sources of older versions, for
+   example in case you want to free up some disk space. The latter will happen
+   automatically when using ``--shallow-since=`` or
+   ``--depth=``.
+
+ * Be warned, when deepening your clone you might encounter an error like
+   'fatal: error in object: unshallow cafecaca0c0dacafecaca0c0dacafecaca0c0da'.
+   In that case run ``git repack -d`` and try again``
+
+ * In case you want to revert changes from a certain version (say Linux 6.3) or
+   perform a bisection (v6.2..v6.3), better tell ``git fetch`` to retrieve
+   objects up to three versions earlier (e.g. 6.0): ``git describe`` will then
+   be able to describe most commits just like it would in a full git clone.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_archive:
+
+Downloading the sources using a packages archive
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+People new to compiling Linux often assume downloading an archive via the
+front-page of https://kernel.org is the best approach to retrieve Linux'
+sources. It actually can be, if you are certain to build just one particular
+kernel version without changing any code. Thing is: you might be sure this will
+be the case, but in practice it often will turn out to be a wrong assumption.
+
+That's because when reporting or debugging an issue developers will often ask to
+give another version a try. They also might suggest temporarily undoing a commit
+with ``git revert`` or might provide various patches to try. Sometimes reporters
+will also be asked to use ``git bisect`` to find the change causing a problem.
+These things rely on git or are a lot easier and quicker to handle with it.
+
+A shallow clone also does not add any significant overhead. For example, when
+you use ``git clone --depth=1`` to create a shallow clone of the latest mainline
+codebase git will only retrieve a little more data than downloading the latest
+mainline pre-release (aka 'rc') via the front-page of kernel.org would.
+
+A shallow clone therefore is often the better choice. If you nevertheless want
+to use a packaged source archive, download one via kernel.org; afterwards
+extract its content to some directory and change to the subdirectory created
+during extraction. The rest of the step-by-step guide will work just fine, apart
+from things that rely on git -- but this mainly concerns the section on
+successive builds of other versions.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_full:
+
+Downloading the sources using a full git clone
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If downloading and storing a lot of data (~4,4 Gigabyte as of early 2023) is
+nothing that bothers you, instead of a shallow clone perform a full git clone
+instead. You then will avoid the specialties mentioned above and will have all
+versions and individual commits at hand at any time::
+
+    curl -L \
+      https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/clone.bundle \
+      -o linux-stable.git.bundle
+    git clone linux-stable.git.bundle ~/linux/
+    rm linux-stable.git.bundle
+    cd ~/linux/
+    git remote set-url origin \
+      https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
+    git fetch origin
+    git checkout --detach origin/master
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_snapshot:
+
+Proper pre-releases (RCs) vs. latest mainline
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When cloning the sources using git and checking out origin/master, you often
+will retrieve a codebase that is somewhere between the latest and the next
+release or pre-release. This almost always is the code you want when giving
+mainline a shot: pre-releases like v6.1-rc5 are in no way special, as they do
+not get any significant extra testing before being published.
+
+There is one exception: you might want to stick to the latest mainline release
+(say v6.1) before its successor's first pre-release (v6.2-rc1) is out. That is
+because compiler errors and other problems are more likely to occur during this
+time, as mainline then is in its 'merge window': a usually two week long phase,
+in which the bulk of the changes for the next release is merged.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_fresher:
+
+Avoiding the mainline lag
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The explanations for both the shallow clone and the full clone both retrieve the
+code from the Linux stable git repository. That makes things simpler for this
+document's audience, as it allows easy access to both mainline and
+stable/longterm releases. This approach has just one downside:
+
+Changes merged into the mainline repository are only synced to the master branch
+of the Linux stable repository  every few hours. This lag most of the time is
+not something to worry about; but in case you really need the latest code, just
+add the mainline repo as additional remote and checkout the code from there::
+
+    git remote add mainline \
+      https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+    git fetch mainline
+    git checkout --detach mainline/master
+
+When doing this with a shallow clone, remember to call ``git fetch`` with one
+of the parameters described earlier to limit the depth.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _patching:
+
+Patch the sources (optional)
+----------------------------
+
+  *In case you want to apply a kernel patch, do so now.*
+  [:ref:`...<patching_sbs>`]
+
+This is the point where you might want to patch your kernel -- for example when
+a developer proposed a fix and asked you to check if it helps. The step-by-step
+guide already explains everything crucial here.
+
+[:ref:`back to step-by-step guide <patching_sbs>`]
+
+.. _tagging:
+
+Tagging this kernel build (optional, often wise)
+------------------------------------------------
+
+  *If you patched your kernel or already have that kernel version installed,
+  better tag your kernel by extending its release name:*
+  [:ref:`...<tagging_sbs>`]
+
+Tagging your kernel will help avoid confusion later, especially when you patched
+your kernel. Adding an individual tag will also ensure the kernel's image and
+its modules are installed in parallel to any existing kernels.
+
+There are various ways to add such a tag. The step-by-step guide realizes one by
+creating a 'localversion' file in your build directory from which the kernel
+build scripts will automatically pick up the tag. You can later change that file
+to use a different tag in subsequent builds or simply remove that file to dump
+the tag.
+
+[:ref:`back to step-by-step guide <tagging_sbs>`]
+
+.. _configuration:
+
+Define the build configuration for your kernel
+----------------------------------------------
+
+  *Create the build configuration for your kernel based on an existing
+  configuration.* [:ref:`... <configuration_sbs>`]
+
+There are various aspects for this steps that require a more careful
+explanation:
+
+Pitfalls when using another configuration file as base
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Make targets like localmodconfig and olddefconfig share a few common snares you
+want to be aware of:
+
+ * These targets will reuse a kernel build configuration in your build directory
+   (e.g. '~/linux/.config'), if one exists. In case you want to start from
+   scratch you thus need to delete it.
+
+ * The make targets try to find the configuration for your running kernel
+   automatically, but might choose poorly. A line like '# using defaults found
+   in /boot/config-6.0.7-250.fc36.x86_64' or 'using config:
+   '/boot/config-6.0.7-250.fc36.x86_64' tells you which file they picked. If
+   that is not the intended one, simply store it as '~/linux/.config'
+   before using these make targets.
+
+ * Unexpected things might happen if you try to use a config file prepared for
+   one kernel (say v6.0) on an older generation (say v5.15). In that case you
+   might want to use a configuration as base which your distribution utilized
+   when they used that or an slightly older kernel version.
+
+Influencing the configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The make target olddefconfig and the ``yes "" |`` used when utilizing
+localmodconfig will set any undefined build options to their default value. This
+among others will disable many kernel features that were introduced after your
+base kernel was released.
+
+If you want to set these configurations options manually, use ``oldconfig``
+instead of ``olddefconfig`` or omit the ``yes "" |`` when utilizing
+localmodconfig. Then for each undefined configuration option you will be asked
+how to proceed. In case you are unsure what to answer, simply hit 'enter' to
+apply the default value.
+
+Big pitfall when using localmodconfig
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As explained briefly in the step-by-step guide already: with localmodconfig it
+can easily happen that your self-built kernel will lack modules for tasks you
+did not perform before utilizing this make target. That's because those tasks
+require kernel modules that are normally autoloaded when you perform that task
+for the first time; if you didn't perform that task at least once before using
+localmodonfig, the latter will thus assume these modules are superfluous and
+disable them.
+
+You can try to avoid this by performing typical tasks that often will autoload
+additional kernel modules: start a VM, establish VPN connections, loop-mount a
+CD/DVD ISO, mount network shares (CIFS, NFS, ...), and connect all external
+devices (2FA keys, headsets, webcams, ...) as well as storage devices with file
+systems you otherwise do not utilize (btrfs, ext4, FAT, NTFS, XFS, ...). But it
+is hard to think of everything that might be needed -- even kernel developers
+often forget one thing or another at this point.
+
+Do not let that risk bother you, especially when compiling a kernel only for
+testing purposes: everything typically crucial will be there. And if you forget
+something important you can turn on a missing feature later and quickly run the
+commands to compile and install a better kernel.
+
+But if you plan to build and use self-built kernels regularly, you might want to
+reduce the risk by recording which modules your system loads over the course of
+a few weeks. You can automate this with `modprobed-db
+<https://github.com/graysky2/modprobed-db>`_. Afterwards use ``LSMOD=<path>`` to
+point localmodconfig to the list of modules modprobed-db noticed being used::
+
+    yes "" | make LSMOD="${HOME}"/.config/modprobed.db localmodconfig
+
+Remote building with localmodconfig
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to use localmodconfig to build a kernel for another machine, run
+``lsmod > lsmod_foo-machine`` on it and transfer that file to your build host.
+Now point the build scripts to the file like this: ``yes "" | make
+LSMOD=~/lsmod_foo-machine localmodconfig``. Note, in this case
+you likely want to copy a base kernel configuration from the other machine over
+as well and place it as .config in your build directory.
+
+[:ref:`back to step-by-step guide <configuration_sbs>`]
+
+.. _configmods:
+
+Adjust build configuration
+--------------------------
+
+   *Check if you might want to or have to adjust some kernel configuration
+   options:*
+
+Depending on your needs you at this point might want or have to adjust some
+kernel configuration options.
+
+.. _configmods_debugsymbols:
+
+Debug symbols
+~~~~~~~~~~~~~
+
+   *Evaluate how you want to handle debug symbols.*
+   [:ref:`...<configmods_sbs>`]
+
+Most users do not need to care about this, it's often fine to leave everything
+as it is; but you should take a closer look at this, if you might need to decode
+a stack trace or want to reduce space consumption.
+
+Having debug symbols available can be important when your kernel throws a
+'panic', 'Oops', 'warning', or 'BUG' later when running, as then you will be
+able to find the exact place where the problem occurred in the code. But
+collecting and embedding the needed debug information takes time and consumes
+quite a bit of space: in late 2022 the build artifacts for a typical x86 kernel
+configured with localmodconfig consumed around 5 Gigabyte of space with debug
+symbols, but less than 1 when they were disabled. The resulting kernel image and
+the modules are bigger as well, which increases load times.
+
+Hence, if you want a small kernel and are unlikely to decode a stack trace
+later, you might want to disable debug symbols to avoid above downsides::
+
+    ./scripts/config --file .config -d DEBUG_INFO \
+      -d DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT -d DEBUG_INFO_DWARF4 \
+      -d DEBUG_INFO_DWARF5 -e CONFIG_DEBUG_INFO_NONE
+    make olddefconfig
+
+You on the other hand definitely want to enable them, if there is a decent
+chance that you need to decode a stack trace later (as explained by 'Decode
+failure messages' in Documentation/admin-guide/tainted-kernels.rst in more
+detail)::
+
+    ./scripts/config --file .config -d DEBUG_INFO_NONE -e DEBUG_KERNEL
+      -e DEBUG_INFO -e DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT -e KALLSYMS -e KALLSYMS_ALL
+    make olddefconfig
+
+Note, many mainstream distributions enable debug symbols in their kernel
+configurations -- make targets like localmodconfig and olddefconfig thus will
+often pick that setting up.

+.. _configmods_distros:
+
+Distro specific adjustments
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+   *Are you running* [:ref:`... <configmods_sbs>`]
+
+The following sections help you to avoid build problems that are known to occur
+when following this guide on a few commodity distributions.
+
+**Debian:**
+
+ * Remove a stale reference to a certificate file that would cause your build to
+   fail::
+
+    ./scripts/config --file .config --set-str SYSTEM_TRUSTED_KEYS ''
+
+   Alternatively, download the needed certificate and make that configuration
+   option point to it, as `the Debian handbook explains in more detail
+   <https://debian-handbook.info/browse/stable/sect.kernel-compilation.html>`_
+   -- or generate your own, as explained in
+   Documentation/admin-guide/module-signing.rst.
+
+[:ref:`back to step-by-step guide <configmods_sbs>`]
+
+.. _configmods_individual:
+
+Individual adjustments
+~~~~~~~~~~~~~~~~~~~~~~
+
+   *If you want to influence the other aspects of the configuration, do so
+   now* [:ref:`... <configmods_sbs>`]
+
+You at this point can use a command like ``make menuconfig`` to enable or
+disable certain features using a text-based user interface; to use a graphical
+configuration utilize, use the make target ``xconfig`` or ``gconfig`` instead.
+All of them require development libraries from toolkits they are based on
+(ncurses, Qt5, Gtk2); an error message will tell you if something required is
+missing.
+
+[:ref:`back to step-by-step guide <configmods_sbs>`]
+
+.. _build:
+
+Build your kernel
+-----------------
+
+  *Build the image and the modules of your kernel* [:ref:`... <build_sbs>`]
+
+A lot can go wrong at this stage, but the instructions below will help you help
+yourself. Another subsection explains how to directly package your kernel up as
+deb, rpm or tar file.
+
+Dealing with build errors
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When a build error occurs, it might be caused by some aspect of your machine's
+setup that often can be fixed quickly; other times though the problem lies in
+the code and can only be fixed by a developer. A close examination of the
+failure messages coupled with some research on the internet will often tell you
+which of the two it is. To perform such a investigation, restart the build
+process like this::
+
+    make V=1
+
+The ``V=1`` activates verbose output, which might be needed to see the actual
+error. To make it easier to spot, this command also omits the ``-j $(nproc
+--all)`` used earlier to utilize every CPU core in the system for the job -- but
+this parallelism also results in some clutter when failures occur.
+
+After a few seconds the build process should run into the error again. Now try
+to find the most crucial line describing the problem. Then search the internet
+for the most important and non-generic section of that line (say 4 to 8 words);
+avoid or remove anything that looks remotely system-specific, like your username
+or local path names like ``/home/username/linux/``. First try your regular
+internet search engine with that string, afterwards search Linux kernel mailing
+lists via `lore.kernel.org/all/ <https://lore.kernel.org/all/>`_.
+
+This most of the time will find something that will explain what is wrong; quite
+often one of the hits will provide a solution for your problem, too. If you
+do not find anything that matches your problem, try again from a different angle
+by modifying your search terms or using another line from the error messages.
+
+In the end, most trouble you are to run into has likely been encountered and
+reported by others already. That includes issues where the cause is not your
+system, but lies the code. If you run into one of those, you might thus find a
+solution (e.g. a patch) or workaround for your problem, too.
+
+Package your kernel up
+~~~~~~~~~~~~~~~~~~~~~~
+
+The step-by-step guide uses the default make targets (e.g. 'bzImage' and
+'modules' on x86) to build the image and the modules of your kernel, which later
+steps of the guide then install. You instead can also directly build everything
+and directly package it up by using one of the following targets:
+
+ * ``make -j $(nproc --all) bindeb-pkg`` to generate a deb package
+
+ * ``make -j $(nproc --all) binrpm-pkg`` to generate a rpm package
+
+ * ``make -j $(nproc --all) tarbz2-pkg`` to generate a bz2 compressed tarball
+
+This is just a selection of available make targets for this purpose, see
+``make help`` for others. You can also use these targets after running
+``make -j $(nproc --all)``, as they will pick up everything already built.
+
+If you employ the targets to generate deb or rpm packages, ignore the
+step-by-step guide's instructions on installing and removing your kernel;
+instead install and remove the packages using the package utility for the format
+(e.g. dpkg and rpm) or a package management utility build on top of them (apt,
+aptitude, dnf/yum, zypper, ...). Be aware that the packages generated using
+these two make targets are designed to work on various distributions utilizing
+those formats, they thus will sometimes behave differently than your
+distribution's kernel packages.
+
+[:ref:`back to step-by-step guide <build_sbs>`]
+
+.. _install:
+
+Install your kernel
+-------------------
+
+  *Now install your kernel* [:ref:`... <install_sbs>`]
+
+What you need to do after executing the command in the step-by-step guide
+depends on the existence and the implementation of an ``installkernel``
+executable. Many commodity Linux distributions ship such a kernel installer in
+``/sbin/`` that does everything needed, hence there is nothing left for you
+except rebooting. But some distributions contain an installkernel that does
+only part of the job -- and a few lack it completely and leave all the work to
+you.
+
+If ``installkernel`` is found, the kernel's build system will delegate the
+actual installation of your kernel's image and related files to this executable.
+On almost all Linux distributions it will store the image as '/boot/vmlinuz-
+<your kernel's release name>' and put a 'System.map-<your kernel's release
+name>' alongside it. Your kernel will thus be installed in parallel to any
+existing ones, unless you already have one with exactly the same release name.
+
+Installkernel on many distributions will afterwards generate an 'initramfs'
+(often also called 'initrd'), which commodity distributions rely on for booting;
+hence be sure to keep the order of the two make targets used in the step-by-step
+guide, as things will go sideways if you install your kernel's image before its
+modules. Often installkernel will then add your kernel to the bootloader
+configuration, too. You have to take care of one or both of these tasks
+yourself, if your distributions installkernel doesn't handle them.
+
+A few distributions like Arch Linux and its derivatives totally lack an
+installkernel executable. On those just install the modules using the kernel's
+build system and then install the image and the System.map file manually::
+
+     sudo make modules_install
+     sudo install -m 0600 $(make -s image_name) /boot/vmlinuz-$(make -s kernelrelease)
+     sudo install -m 0600 System.map /boot/System.map-$(make -s kernelrelease)
+
+If your distribution boots with the help of an initramfs, now generate one for
+your kernel using the tools your distribution provides for this process.
+Afterwards add your kernel to your bootloader configuration and reboot.
+
+[:ref:`back to step-by-step guide <install_sbs>`]
+
+.. _another:
+
+Another round later
+-------------------
+
+  *To later build another kernel you need similar, but sometimes slightly
+  different commands* [:ref:`... <another_sbs>`]
+
+The process to build later kernels is similar, but at some points slightly
+different. You for example do not want to use 'localmodconfig' for succeeding
+kernel builds, as you already created a trimmed down configuration you want to
+use from now on. Hence instead just use ``oldconfig`` or ``olddefconfig`` to
+adjust your build configurations to the needs of the kernel version you are
+about to build.
+
+If you created a shallow-clone with git, remember what the :ref:`section that
+explained the setup described in more detail <sources>`: you need to use a
+slightly different ``git fetch`` command and when switching to another series
+need to add an additional remote branch.
+
+[:ref:`back to step-by-step guide <another_sbs>`]
+
+.. _uninstall:
+
+Uninstall the kernel later
+--------------------------
+
+  *All parts of your installed kernel are identifiable by its release name and
+  thus easy to remove later.* [:ref:`... <uninstall_sbs>`]
+
+Do not worry installing your kernel manually and thus bypassing your
+distribution's packaging system will totally mess up your machine: all parts of
+your kernel are easy to remove later, as files are stored in two places only and
+normally identifiable by the kernel's release name.
+
+One of the two places is a directory in /lib/modules/, which holds the modules
+for each installed kernel. This directory is named after the kernel's release
+name; hence, to remove all modules for one of your kernels, simply remove its
+modules directory in /lib/modules/.
+
+The other place is /boot/, where typically one to five files will be placed
+during installation of a kernel. All of them usually contain the release name in
+their file name, but how many files and their name depends somewhat on your
+distribution's installkernel executable (:ref:`see above <install>`) and its
+initramfs generator. On some distributions the ``kernel-install`` command
+mentioned in the step-by-step guide will remove all of these files for you --
+and the entry for your kernel in the bootloader configuration at the same time,
+too. On others you have to take care of these steps yourself. The following
+command should interactively remove the two main files of a kernel with the
+release name '6.0.1-foobar'::
+
+    rm -i /boot/{System.map,vmlinuz}-6.0.1-foobar
+
+Now remove the belonging initramfs, which often will be called something like
+``/boot/initramfs-6.0.1-foobar.img`` or ``/boot/initrd.img-6.0.1-foobar``.
+Afterwards check for other files in /boot/ that have '6.0.1-foobar' in their
+name and delete them as well. Now remove the kernel from your bootloader's
+configuration.
+
+Note, be very careful with wildcards like '*' when deleting files or directories
+for kernels manually: you might accidentally remove files of a 6.0.11 kernel
+when all you want is to remove 6.0 or 6.0.1.

+
+As initially stated, this guide is 'designed to cover everything typically
+needed [to build a kernel] on mainstream Linux distributions running on
+commodity PC or server hardware'. The outlined approach despite this should work
+on many other setups as well. But trying to cover every possible use-case in one
+guide would defeat its purpose, as without such a focus you would need dozens or
+hundreds of constructs along the lines of 'in case you are having <insert
+machine or distro>, you at this point have to do <this and that>
+<instead|additionally>'. Each of which would make the text longer, more
+complicated, and harder to follow.
+
+That being said: this of course is a balancing act. Hence, if you think an
+additional use-case is worth describing, suggest it to the maintainers of this
+document, as :ref:`described above <submit_improvements>`.

 virtual console, and kernel messages will appear on both the VGA
 console and the 2nd serial port (ttyS1 or COM2) at 9600 baud.
 
-Note that you can only define one console per device type (serial, video).
+The behavior is more complicated when the same device type is defined more
+times. In this case, there are the following two rules:
+
+1. The output will appear only on the first device of each defined type.
+
+2. ``/dev/console`` will be associated with the first registered device.
+   Where the registration order depends on how kernel initializes various
+   subsystems.
+
+   This rule is used also when the last console= parameter is not used
+   for other reasons. For example, because of a typo or because
+   the hardware is not available.
+
+The result might be surprising. For example, the following two command
+lines have the same result:
+
+	console=ttyS1,9600 console=tty0 console=tty1
+	console=tty0 console=ttyS1,9600 console=tty1
+
+The kernel messages are printed only on ``tty0`` and ``ttyS1``. And
+``/dev/console`` gets associated with ``tty0``. It is because kernel
+tries to register graphical consoles before serial ones. It does it
+because of the default behavior when no console device is specified,
+see below.
+
+Note that the last ``console=tty1`` parameter still makes a difference.
+The kernel command line is used also by systemd. It would use the last
+defined ``tty1`` as the login console.

 acting as a system console will be used. At this time, the system

+Using XSTATE features in user space applications
+================================================
+
+The x86 architecture supports floating-point extensions which are
+enumerated via CPUID. Applications consult CPUID and use XGETBV to
+evaluate which features have been enabled by the kernel XCR0.
+
+Up to AVX-512 and PKRU states, these features are automatically enabled by
+the kernel if available. Features like AMX TILE_DATA (XSTATE component 18)
+are enabled by XCR0 as well, but the first use of related instruction is
+trapped by the kernel because by default the required large XSTATE buffers
+are not allocated automatically.
+
+The purpose for dynamic features
+--------------------------------
+
+Legacy userspace libraries often have hard-coded, static sizes for
+alternate signal stacks, often using MINSIGSTKSZ which is typically 2KB.
+That stack must be able to store at *least* the signal frame that the
+kernel sets up before jumping into the signal handler. That signal frame
+must include an XSAVE buffer defined by the CPU.
+
+However, that means that the size of signal stacks is dynamic, not static,
+because different CPUs have differently-sized XSAVE buffers. A compiled-in
+size of 2KB with existing applications is too small for new CPU features
+like AMX. Instead of universally requiring larger stack, with the dynamic
+enabling, the kernel can enforce userspace applications to have
+properly-sized altstacks.
+
+Using dynamically enabled XSTATE features in user space applications
+--------------------------------------------------------------------
+
+The kernel provides an arch_prctl(2) based mechanism for applications to
+request the usage of such features. The arch_prctl(2) options related to
+this are:
+
+-ARCH_GET_XCOMP_SUPP
+
+ arch_prctl(ARCH_GET_XCOMP_SUPP, &features);
+
+ ARCH_GET_XCOMP_SUPP stores the supported features in userspace storage of
+ type uint64_t. The second argument is a pointer to that storage.
+
+-ARCH_GET_XCOMP_PERM
+
+ arch_prctl(ARCH_GET_XCOMP_PERM, &features);
+
+ ARCH_GET_XCOMP_PERM stores the features for which the userspace process
+ has permission in userspace storage of type uint64_t. The second argument
+ is a pointer to that storage.
+
+-ARCH_REQ_XCOMP_PERM
+
+ arch_prctl(ARCH_REQ_XCOMP_PERM, feature_nr);
+
+ ARCH_REQ_XCOMP_PERM allows to request permission for a dynamically enabled
+ feature or a feature set. A feature set can be mapped to a facility, e.g.
+ AMX, and can require one or more XSTATE components to be enabled.
+
+ The feature argument is the number of the highest XSTATE component which
+ is required for a facility to work.
+
+When requesting permission for a feature, the kernel checks the
+availability. The kernel ensures that sigaltstacks in the process's tasks
+are large enough to accommodate the resulting large signal frame. It
+enforces this both during ARCH_REQ_XCOMP_SUPP and during any subsequent
+sigaltstack(2) calls. If an installed sigaltstack is smaller than the
+resulting sigframe size, ARCH_REQ_XCOMP_SUPP results in -ENOSUPP. Also,
+sigaltstack(2) results in -ENOMEM if the requested altstack is too small
+for the permitted features.
+
+Permission, when granted, is valid per process. Permissions are inherited
+on fork(2) and cleared on exec(3).
+
+The first use of an instruction related to a dynamically enabled feature is
+trapped by the kernel. The trap handler checks whether the process has
+permission to use the feature. If the process has no permission then the
+kernel sends SIGILL to the application. If the process has permission then
+the handler allocates a larger xstate buffer for the task so the large
+state can be context switched. In the unlikely cases that the allocation
+fails, the kernel sends SIGSEGV.
+
+AMX TILE_DATA enabling example
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Below is the example of how userspace applications enable
+TILE_DATA dynamically:
+
+  1. The application first needs to query the kernel for AMX
+     support::
+
+        #include <asm/prctl.h>
+        #include <sys/syscall.h>
+        #include <stdio.h>
+        #include <unistd.h>
+
+        #ifndef ARCH_GET_XCOMP_SUPP
+        #define ARCH_GET_XCOMP_SUPP  0x1021
+        #endif
+
+        #ifndef ARCH_XCOMP_TILECFG
+        #define ARCH_XCOMP_TILECFG   17
+        #endif
+
+        #ifndef ARCH_XCOMP_TILEDATA
+        #define ARCH_XCOMP_TILEDATA  18
+        #endif
+
+        #define MASK_XCOMP_TILE      ((1 << ARCH_XCOMP_TILECFG) | \
+                                      (1 << ARCH_XCOMP_TILEDATA))
+
+        unsigned long features;
+        long rc;
+
+        ...
+
+        rc = syscall(SYS_arch_prctl, ARCH_GET_XCOMP_SUPP, &features);
+
+        if (!rc && (features & MASK_XCOMP_TILE) == MASK_XCOMP_TILE)
+            printf("AMX is available.\n");
+
+  2. After that, determining support for AMX, an application must
+     explicitly ask permission to use it::
+
+        #ifndef ARCH_REQ_XCOMP_PERM
+        #define ARCH_REQ_XCOMP_PERM  0x1023
+        #endif
+
+        ...
+
+        rc = syscall(SYS_arch_prctl, ARCH_REQ_XCOMP_PERM, ARCH_XCOMP_TILEDATA);
+
+        if (!rc)
+            printf("AMX is ready for use.\n");
+
+Note this example does not include the sigaltstack preparation.
+
+Dynamic features in signal frames
+---------------------------------
+
+Dynamcally enabled features are not written to the signal frame upon signal
+entry if the feature is in its initial configuration.  This differs from
+non-dynamic features which are always written regardless of their
+configuration.  Signal handlers can examine the XSAVE buffer's XSTATE_BV
+field to determine if a features was written.
+
+Dynamic features for virtual machines
+-------------------------------------
+
+The permission for the guest state component needs to be managed separately
+from the host, as they are exclusive to each other. A coupled of options
+are extended to control the guest permission:
+
+-ARCH_GET_XCOMP_GUEST_PERM
+
+ arch_prctl(ARCH_GET_XCOMP_GUEST_PERM, &features);
+
+ ARCH_GET_XCOMP_GUEST_PERM is a variant of ARCH_GET_XCOMP_PERM. So it
+ provides the same semantics and functionality but for the guest
+ components.
+
+-ARCH_REQ_XCOMP_GUEST_PERM
+
+ arch_prctl(ARCH_REQ_XCOMP_GUEST_PERM, feature_nr);
+
+ ARCH_REQ_XCOMP_GUEST_PERM is a variant of ARCH_REQ_XCOMP_PERM. It has the
+ same semantics for the guest permission. While providing a similar
+ functionality, this comes with a constraint. Permission is frozen when the
+ first VCPU is created. Any attempt to change permission after that point
+ is going to be rejected. So, the permission has to be requested before the
+ first VCPU creation.
+
+Note that some VMMs may have already established a set of supported state
+components. These options are not presumed to support any particular VMM.

 The eBPF program needs to store the return value into register R0 before doing a
-BPF_EXIT.
+``BPF_EXIT``.
+
+Example:
+
+``BPF_JSGE | BPF_X | BPF_JMP32`` (0x7e) means::
+
+  if (s32)dst s>= (s32)src goto +offset
+
+where 's>=' indicates a signed '>=' comparison.
 
+Helper functions
+~~~~~~~~~~~~~~~~
+
+Helper functions are a concept whereby BPF programs can call into a
+set of function calls exposed by the underlying platform.
+
+Historically, each helper function was identified by an address
+encoded in the imm field.  The available helper functions may differ
+for each program type, but address values are unique across all program types.
+
+Platforms that support the BPF Type Format (BTF) support identifying
+a helper function by a BTF ID encoded in the imm field, where the BTF ID
+identifies the helper name and type.
+
+Program-local functions
+~~~~~~~~~~~~~~~~~~~~~~~
+Program-local functions are functions exposed by the same BPF program as the
+caller, and are referenced by offset from the call instruction, similar to
+``BPF_JA``.  A ``BPF_EXIT`` within the program-local function will return to
+the caller.

+libbpf Overview
+===============
+
+libbpf is a C-based library containing a BPF loader that takes compiled BPF
+object files and prepares and loads them into the Linux kernel. libbpf takes the
+heavy lifting of loading, verifying, and attaching BPF programs to various
+kernel hooks, allowing BPF application developers to focus only on BPF program
+correctness and performance.
+
+The following are the high-level features supported by libbpf:
+
+* Provides high-level and low-level APIs for user space programs to interact
+  with BPF programs. The low-level APIs wrap all the bpf system call
+  functionality, which is useful when users need more fine-grained control
+  over the interactions between user space and BPF programs.
+* Provides overall support for the BPF object skeleton generated by bpftool.
+  The skeleton file simplifies the process for the user space programs to access
+  global variables and work with BPF programs.
+* Provides BPF-side APIS, including BPF helper definitions, BPF maps support,
+  and tracing helpers, allowing developers to simplify BPF code writing.
+* Supports BPF CO-RE mechanism, enabling BPF developers to write portable
+  BPF programs that can be compiled once and run across different kernel
+  versions.
+
+This document will delve into the above concepts in detail, providing a deeper
+understanding of the capabilities and advantages of libbpf and how it can help
+you develop BPF applications efficiently.
+
+BPF App Lifecycle and libbpf APIs
+==================================
+
+A BPF application consists of one or more BPF programs (either cooperating or
+completely independent), BPF maps, and global variables. The global
+variables are shared between all BPF programs, which allows them to cooperate on
+a common set of data. libbpf provides APIs that user space programs can use to
+manipulate the BPF programs by triggering different phases of a BPF application
+lifecycle.
+
+The following section provides a brief overview of each phase in the BPF life
+cycle:
+
+* **Open phase**: In this phase, libbpf parses the BPF
+  object file and discovers BPF maps, BPF programs, and global variables. After
+  a BPF app is opened, user space apps can make additional adjustments
+  (setting BPF program types, if necessary; pre-setting initial values for
+  global variables, etc.) before all the entities are created and loaded.
+
+* **Load phase**: In the load phase, libbpf creates BPF
+  maps, resolves various relocations, and verifies and loads BPF programs into
+  the kernel. At this point, libbpf validates all the parts of a BPF application
+  and loads the BPF program into the kernel, but no BPF program has yet been
+  executed. After the load phase, it’s possible to set up the initial BPF map
+  state without racing with the BPF program code execution.
+
+* **Attachment phase**: In this phase, libbpf
+  attaches BPF programs to various BPF hook points (e.g., tracepoints, kprobes,
+  cgroup hooks, network packet processing pipeline, etc.). During this
+  phase, BPF programs perform useful work such as processing
+  packets, or updating BPF maps and global variables that can be read from user
+  space.
+
+* **Tear down phase**: In the tear down phase,
+  libbpf detaches BPF programs and unloads them from the kernel. BPF maps are
+  destroyed, and all the resources used by the BPF app are freed.
+
+BPF Object Skeleton File
+========================
+
+BPF skeleton is an alternative interface to libbpf APIs for working with BPF
+objects. Skeleton code abstract away generic libbpf APIs to significantly
+simplify code for manipulating BPF programs from user space. Skeleton code
+includes a bytecode representation of the BPF object file, simplifying the
+process of distributing your BPF code. With BPF bytecode embedded, there are no
+extra files to deploy along with your application binary.
+
+You can generate the skeleton header file ``(.skel.h)`` for a specific object
+file by passing the BPF object to the bpftool. The generated BPF skeleton
+provides the following custom functions that correspond to the BPF lifecycle,
+each of them prefixed with the specific object name:
+
+* ``<name>__open()`` – creates and opens BPF application (``<name>`` stands for
+  the specific bpf object name)
+* ``<name>__load()`` – instantiates, loads,and verifies BPF application parts
+* ``<name>__attach()`` – attaches all auto-attachable BPF programs (it’s
+  optional, you can have more control by using libbpf APIs directly)
+* ``<name>__destroy()`` – detaches all BPF programs and
+  frees up all used resources
+
+Using the skeleton code is the recommended way to work with bpf programs. Keep
+in mind, BPF skeleton provides access to the underlying BPF object, so whatever
+was possible to do with generic libbpf APIs is still possible even when the BPF
+skeleton is used. It's an additive convenience feature, with no syscalls, and no
+cumbersome code.
+
+Other Advantages of Using Skeleton File
+---------------------------------------
+
+* BPF skeleton provides an interface for user space programs to work with BPF
+  global variables. The skeleton code memory maps global variables as a struct
+  into user space. The struct interface allows user space programs to initialize
+  BPF programs before the BPF load phase and fetch and update data from user
+  space afterward.
+
+* The ``skel.h`` file reflects the object file structure by listing out the
+  available maps, programs, etc. BPF skeleton provides direct access to all the
+  BPF maps and BPF programs as struct fields. This eliminates the need for
+  string-based lookups with ``bpf_object_find_map_by_name()`` and
+  ``bpf_object_find_program_by_name()`` APIs, reducing errors due to BPF source
+  code and user-space code getting out of sync.
+
+* The embedded bytecode representation of the object file ensures that the
+  skeleton and the BPF object file are always in sync.
+
+BPF Helpers
+===========
+
+libbpf provides BPF-side APIs that BPF programs can use to interact with the
+system. The BPF helpers definition allows developers to use them in BPF code as
+any other plain C function. For example, there are helper functions to print
+debugging messages, get the time since the system was booted, interact with BPF
+maps, manipulate network packets, etc.
+
+For a complete description of what the helpers do, the arguments they take, and
+the return value, see the `bpf-helpers
+<https://man7.org/linux/man-pages/man7/bpf-helpers.7.html>`_ man page.
+
+BPF CO-RE (Compile Once – Run Everywhere)
+=========================================
+
+BPF programs work in the kernel space and have access to kernel memory and data
+structures. One limitation that BPF applications come across is the lack of
+portability across different kernel versions and configurations. `BCC
+<https://github.com/iovisor/bcc/>`_ is one of the solutions for BPF
+portability. However, it comes with runtime overhead and a large binary size
+from embedding the compiler with the application.
+
+libbpf steps up the BPF program portability by supporting the BPF CO-RE concept.
+BPF CO-RE brings together BTF type information, libbpf, and the compiler to
+produce a single executable binary that you can run on multiple kernel versions
+and configurations.
+
+To make BPF programs portable libbpf relies on the BTF type information of the
+running kernel. Kernel also exposes this self-describing authoritative BTF
+information through ``sysfs`` at ``/sys/kernel/btf/vmlinux``.
+
+You can generate the BTF information for the running kernel with the following
+command:
+
+::
+
+  $ bpftool btf dump file /sys/kernel/btf/vmlinux format c > vmlinux.h
+
+The command generates a ``vmlinux.h`` header file with all kernel types
+(:doc:`BTF types <../btf>`) that the running kernel uses. Including
+``vmlinux.h`` in your BPF program eliminates dependency on system-wide kernel
+headers.
+
+libbpf enables portability of BPF programs by looking at the BPF program’s
+recorded BTF type and relocation information and matching them to BTF
+information (vmlinux) provided by the running kernel. libbpf then resolves and
+matches all the types and fields, and updates necessary offsets and other
+relocatable data to ensure that BPF program’s logic functions correctly for a
+specific kernel on the host. BPF CO-RE concept thus eliminates overhead
+associated with BPF development and allows developers to write portable BPF
+applications without modifications and runtime source code compilation on the
+target machine.
+
+The following code snippet shows how to read the parent field of a kernel
+``task_struct`` using BPF CO-RE and libbf. The basic helper to read a field in a
+CO-RE relocatable manner is ``bpf_core_read(dst, sz, src)``, which will read
+``sz`` bytes from the field referenced by ``src`` into the memory pointed to by
+``dst``.
+
+.. code-block:: C
+   :emphasize-lines: 6
+
+    //...
+    struct task_struct *task = (void *)bpf_get_current_task();
+    struct task_struct *parent_task;
+    int err;
+
+    err = bpf_core_read(&parent_task, sizeof(void *), &task->parent);
+    if (err) {
+      /* handle error */
+    }
+
+    /* parent_task contains the value of task->parent pointer */
+
+In the code snippet, we first get a pointer to the current ``task_struct`` using
+``bpf_get_current_task()``.  We then use ``bpf_core_read()`` to read the parent
+field of task struct into the ``parent_task`` variable. ``bpf_core_read()`` is
+just like ``bpf_probe_read_kernel()`` BPF helper, except it records information
+about the field that should be relocated on the target kernel. i.e, if the
+``parent`` field gets shifted to a different offset within
+``struct task_struct`` due to some new field added in front of it, libbpf will
+automatically adjust the actual offset to the proper value.
+
+Getting Started with libbpf
+===========================
+
+Check out the `libbpf-bootstrap <https://github.com/libbpf/libbpf-bootstrap>`_
+repository with simple examples of using libbpf to build various BPF
+applications.
+
+See also `libbpf API documentation
+<https://libbpf.readthedocs.io/en/latest/api.html>`_.
+
+libbpf and Rust
+===============
+
+If you are building BPF applications in Rust, it is recommended to use the
+`Libbpf-rs <https://github.com/libbpf/libbpf-rs>`_ library instead of bindgen
+bindings directly to libbpf. Libbpf-rs wraps libbpf functionality in
+Rust-idiomatic interfaces and provides libbpf-cargo plugin to handle BPF code
+compilation and skeleton generation. Using Libbpf-rs will make building user
+space part of the BPF application easier. Note that the BPF program themselves
+must still be written in plain C.

 Remote coverage collection
 --------------------------
 
-With KCOV_ENABLE coverage is collected only for syscalls that are issued
-from the current process. With KCOV_REMOTE_ENABLE it's possible to collect
-coverage for arbitrary parts of the kernel code, provided that those parts
-are annotated with kcov_remote_start()/kcov_remote_stop().
-
-This allows to collect coverage from two types of kernel background
-threads: the global ones, that are spawned during kernel boot in a limited
-number of instances (e.g. one USB hub_event() worker thread is spawned per
-USB HCD); and the local ones, that are spawned when a user interacts with
-some kernel interface (e.g. vhost workers); as well as from soft
-interrupts.
-
-To enable collecting coverage from a global background thread or from a
-softirq, a unique global handle must be assigned and passed to the
-corresponding kcov_remote_start() call. Then a userspace process can pass
-a list of such handles to the KCOV_REMOTE_ENABLE ioctl in the handles
-array field of the kcov_remote_arg struct. This will attach the used kcov
-device to the code sections, that are referenced by those handles.
-
-Since there might be many local background threads spawned from different
-userspace processes, we can't use a single global handle per annotation.
-Instead, the userspace process passes a non-zero handle through the
-common_handle field of the kcov_remote_arg struct. This common handle gets
-saved to the kcov_handle field in the current task_struct and needs to be
-passed to the newly spawned threads via custom annotations. Those threads
-should in turn be annotated with kcov_remote_start()/kcov_remote_stop().
-
-Internally kcov stores handles as u64 integers. The top byte of a handle
-is used to denote the id of a subsystem that this handle belongs to, and
-the lower 4 bytes are used to denote the id of a thread instance within
-that subsystem. A reserved value 0 is used as a subsystem id for common
-handles as they don't belong to a particular subsystem. The bytes 4-7 are
-currently reserved and must be zero. In the future the number of bytes
-used for the subsystem or handle ids might be increased.
-
-When a particular userspace process collects coverage via a common
-handle, kcov will collect coverage for each code section that is annotated
-to use the common handle obtained as kcov_handle from the current
-task_struct. However non common handles allow to collect coverage
-selectively from different subsystems.
+Besides collecting coverage data from handlers of syscalls issued from a
+userspace process, KCOV can also collect coverage for parts of the kernel
+executing in other contexts - so-called "remote" coverage.
+
+Using KCOV to collect remote coverage requires:
+
+1. Modifying kernel code to annotate the code section from where coverage
+   should be collected with ``kcov_remote_start`` and ``kcov_remote_stop``.
+
+2. Using ``KCOV_REMOTE_ENABLE`` instead of ``KCOV_ENABLE`` in the userspace
+   process that collects coverage.
+
+Both ``kcov_remote_start`` and ``kcov_remote_stop`` annotations and the
+``KCOV_REMOTE_ENABLE`` ioctl accept handles that identify particular coverage
+collection sections. The way a handle is used depends on the context where the
+matching code section executes.
+
+KCOV supports collecting remote coverage from the following contexts:
+
+1. Global kernel background tasks. These are the tasks that are spawned during
+   kernel boot in a limited number of instances (e.g. one USB ``hub_event``
+   worker is spawned per one USB HCD).
+
+2. Local kernel background tasks. These are spawned when a userspace process
+   interacts with some kernel interface and are usually killed when the process
+   exits (e.g. vhost workers).
+
+3. Soft interrupts.
+
+For #1 and #3, a unique global handle must be chosen and passed to the
+corresponding ``kcov_remote_start`` call. Then a userspace process must pass
+this handle to ``KCOV_REMOTE_ENABLE`` in the ``handles`` array field of the
+``kcov_remote_arg`` struct. This will attach the used KCOV device to the code
+section referenced by this handle. Multiple global handles identifying
+different code sections can be passed at once.
+
+For #2, the userspace process instead must pass a non-zero handle through the
+``common_handle`` field of the ``kcov_remote_arg`` struct. This common handle
+gets saved to the ``kcov_handle`` field in the current ``task_struct`` and
+needs to be passed to the newly spawned local tasks via custom kernel code
+modifications. Those tasks should in turn use the passed handle in their
+``kcov_remote_start`` and ``kcov_remote_stop`` annotations.
+
+KCOV follows a predefined format for both global and common handles. Each
+handle is a ``u64`` integer. Currently, only the one top and the lower 4 bytes
+are used. Bytes 4-7 are reserved and must be zero.
+
+For global handles, the top byte of the handle denotes the id of a subsystem
+this handle belongs to. For example, KCOV uses ``1`` as the USB subsystem id.
+The lower 4 bytes of a global handle denote the id of a task instance within
+that subsystem. For example, each ``hub_event`` worker uses the USB bus number
+as the task instance id.
+
+For common handles, a reserved value ``0`` is used as a subsystem id, as such
+handles don't belong to a particular subsystem. The lower 4 bytes of a common
+handle identify a collective instance of all local tasks spawned by the
+userspace process that passed a common handle to ``KCOV_REMOTE_ENABLE``.
+
+In practice, any value can be used for common handle instance id if coverage
+is only collected from a single userspace process on the system. However, if
+common handles are used by multiple processes, unique instance ids must be
+used for each process. One option is to use the process id as the common
+handle instance id.
+
+The following program demonstrates using KCOV to collect coverage from both
+local tasks spawned by the process and the global task that handles USB bus #1:

-description: |
-  LLCC (Last Level Cache Controller) provides last level of cache memory in SoC,
-  that can be shared by multiple clients. Clients here are different cores in the
-  SoC, the idea is to minimize the local caches at the clients and migrate to
-  common pool of memory. Cache memory is divided into partitions called slices
-  which are assigned to clients. Clients can query the slice details, activate
-  and deactivate them.

+title: AMD CDX bus controller
+
+description: |
+  CDX bus controller for AMD devices is implemented to dynamically
+  detect CDX bus and devices using the firmware.
+  The CDX bus manages multiple FPGA based hardware devices, which
+  can support network, crypto or any other specialized type of
+  devices. These FPGA based devices can be added/modified dynamically
+  on run-time.
+
+  All devices on the CDX bus will have a unique streamid (for IOMMU)
+  and a unique device ID (for MSI) corresponding to a requestor ID
+  (one to one associated with the device). The streamid and deviceid
+  are used to configure SMMU and GIC-ITS respectively.
+
+  iommu-map property is used to define the set of stream ids
+  corresponding to each device and the associated IOMMU.
+
+  The MSI writes are accompanied by sideband data (Device ID).
+  The msi-map property is used to associate the devices with the
+  device ID as well as the associated ITS controller.
+
+  rproc property (xlnx,rproc) is used to identify the remote processor
+  with which APU (Application Processor Unit) interacts to find out
+  the bus and device configuration.

+  LLCC (Last Level Cache Controller) provides last level of cache memory in SoC,
+  that can be shared by multiple clients. Clients here are different cores in the
+  SoC, the idea is to minimize the local caches at the clients and migrate to
+  common pool of memory. Cache memory is divided into partitions called slices
+  which are assigned to clients. Clients can query the slice details, activate
+  and deactivate them.

+
+  The apmixedsys provides most of PLLs which generated from SoC 26m.
+  The topckgen provides dividers and muxes which provide the clock source to other IP blocks.
+  The infracfg_ao provides clock gate in peripheral and infrastructure IP blocks.
+  The mcusys provides mux control to select the clock source in AP MCU.
+  The device nodes also provide the system control capacity for configuration.

+description:
+  ETHDR (ET High Dynamic Range) is a MediaTek internal HDR engine and is
+  designed for HDR video and graphics conversion in the external display path.
+  It handles multiple HDR input types and performs tone mapping, color
+  space/color format conversion, and then combine different layers,
+  output the required HDR or SDR signal to the subsequent display path.
+  This engine is composed of two video frontends, two graphic frontends,
+  one video backend and a mixer. ETHDR has two DMA function blocks, DS and ADL.
+  These two function blocks read the pre-programmed registers from DRAM and
+  set them to HW in the v-blanking period.

-Rockchip RK3288 LVDS interface
-================================
-
-Required properties:
-- compatible: matching the soc type, one of
-	- "rockchip,rk3288-lvds";
-	- "rockchip,px30-lvds";
-
-- reg: physical base address of the controller and length
-	of memory mapped region.
-- clocks: must include clock specifiers corresponding to entries in the
-	clock-names property.
-- clock-names: must contain "pclk_lvds"
-
-- avdd1v0-supply: regulator phandle for 1.0V analog power
-- avdd1v8-supply: regulator phandle for 1.8V analog power
-- avdd3v3-supply: regulator phandle for 3.3V analog power
-
-- rockchip,grf: phandle to the general register files syscon
-- rockchip,output: "rgb", "lvds" or "duallvds", This describes the output interface
-
-- phys: LVDS/DSI DPHY (px30 only)
-- phy-names: name of the PHY, must be "dphy" (px30 only)
-
-Optional properties:
-- pinctrl-names: must contain a "lcdc" entry.
-- pinctrl-0: pin control group to be used for this controller.
-
-Required nodes:
-
-The lvds has two video ports as described by
-	Documentation/devicetree/bindings/media/video-interfaces.txt
-Their connections are modeled using the OF graph bindings specified in
-	Documentation/devicetree/bindings/graph.txt.
-
-- video port 0 for the VOP input, the remote endpoint maybe vopb or vopl
-- video port 1 for either a panel or subsequent encoder

+GPIO controller.
+
+For lines which are routed to on-board devices, this name should be
+the most meaningful producer name for the system, such as a rail name
+indicating the usage. Package names, such as a pin name, are discouraged:
+such lines have opaque names (since they are by definition general-purpose)
+and such names are usually not very helpful. For example "MMC-CD", "Red LED
+Vdd" and "ethernet reset" are reasonable line names as they describe what
+the line is used for. "GPIO0" is not a good name to give to a GPIO line
+that is hard-wired to a specific device.
+
+However, in the case of lines that are routed to a general purpose header
+(e.g. the Raspberry Pi 40-pin header), and therefore are not hard-wired to
+specific devices, using a pin number or the names on the header is fine
+provided these are real (preferably unique) names. Using an SoC's pad name
+or package name, or names made up from kernel-internal software constructs,
+are strongly discouraged. For example "pin8 [gpio14/uart0_txd]" is fine
+if the board's documentation labels pin 8 as such. However "PortB_24" (an
+example of a name from an SoC's reference manual) would not be desirable.
+
+In either case placeholders are discouraged: rather use the "" (blank
+string) if the use of the GPIO line is undefined in your design. Ideally,
+try to add comments to the dts file describing the naming the convention
+you have chosen, and specifying from where the names are derived.
+
+The names are assigned starting from line offset 0, from left to right,
+from the passed array. An incomplete array (where the number of passed
+names is less than ngpios) will be used up until the last provided valid
+line index.

-Bindings for a fan connected to the PWM lines
-
-Required properties:
-- compatible	: "pwm-fan"
-- pwms		: the PWM that is used to control the PWM fan
-- cooling-levels      : PWM duty cycle values in a range from 0 to 255
-			which correspond to thermal cooling states
-
-Optional properties:
-- fan-supply		: phandle to the regulator that provides power to the fan
-- interrupts		: This contains an interrupt specifier for each fan
-			  tachometer output connected to an interrupt source.
-			  The output signal must generate a defined number of
-			  interrupts per fan revolution, which require that
-			  it must be self resetting edge interrupts. See
-			  interrupt-controller/interrupts.txt for the format.
-- pulses-per-revolution : define the number of pulses per fan revolution for
-			  each tachometer input as an integer (default is 2
-			  interrupts per revolution). The value must be
-			  greater than zero.
-
-Example:
-	fan0: pwm-fan {
-		compatible = "pwm-fan";
-		#cooling-cells = <2>;
-		pwms = <&pwm 0 10000 0>;
-		cooling-levels = <0 102 170 230>;
-	};
-
-	thermal-zones {
-		cpu_thermal: cpu-thermal {
-			     thermal-sensors = <&tmu 0>;
-			     polling-delay-passive = <0>;
-			     polling-delay = <0>;
-			     trips {
-					cpu_alert1: cpu-alert1 {
-						    temperature = <100000>; /* millicelsius */
-						    hysteresis = <2000>; /* millicelsius */
-						    type = "passive";
-					};
-			     };
-			     cooling-maps {
-					map0 {
-						    trip = <&cpu_alert1>;
-						    cooling-device = <&fan0 0 1>;
-					};
-			     };
-		};
-
-Example 2:
-	fan0: pwm-fan {
-		compatible = "pwm-fan";
-		pwms = <&pwm 0 40000 0>;
-		fan-supply = <&reg_fan>;
-		interrupt-parent = <&gpio5>;
-		interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
-		pulses-per-revolution = <2>;

-Example 3:
-	fan0: pwm-fan {
-		compatible = "pwm-fan";
-		pwms = <&pwm1 0 25000 0>;
-		interrupts-extended = <&gpio1 1 IRQ_TYPE_EDGE_FALLING>,

-Broadcom Kona Family I2C
-=========================
-
-This I2C controller is used in the following Broadcom SoCs:
-
-  BCM11130
-  BCM11140
-  BCM11351
-  BCM28145
-  BCM28155
-
-Required Properties
--------------------
-- compatible: "brcm,bcm11351-i2c", "brcm,kona-i2c"
-- reg: Physical base address and length of controller registers
-- interrupts: The interrupt number used by the controller
-- clocks: clock specifier for the kona i2c external clock
-- clock-frequency: The I2C bus frequency in Hz
-- #address-cells: Should be <1>
-- #size-cells: Should be <0>
-
-Refer to clocks/clock-bindings.txt for generic clock consumer
-properties.

-* PWM beeper device tree bindings
-
-Registers a PWM device as beeper.
-
-Required properties:
-- compatible: should be "pwm-beeper"
-- pwms: phandle to the physical PWM device
-
-Optional properties:
-- amp-supply: phandle to a regulator that acts as an amplifier for the beeper
-- beeper-hz:  bell frequency in Hz
-
-Example:
-
-beeper_amp: amplifier {
-	compatible = "fixed-regulator";
-	gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
-};
-
-beeper {
-	compatible = "pwm-beeper";
-	pwms = <&pwm0>;
-	amp-supply = <&beeper_amp>;
-};

-* QCOM IOMMU v1 Implementation
-
-Qualcomm "B" family devices which are not compatible with arm-smmu have
-a similar looking IOMMU but without access to the global register space,
-and optionally requiring additional configuration to route context irqs
-to non-secure vs secure interrupt line.
-
-** Required properties:
-
-- compatible       : Should be one of:
-
-                        "qcom,msm8916-iommu"
-                        "qcom,msm8953-iommu"
-
-                     Followed by "qcom,msm-iommu-v1".
-
-- clock-names      : Should be a pair of "iface" (required for IOMMUs
-                     register group access) and "bus" (required for
-                     the IOMMUs underlying bus access).
-
-- clocks           : Phandles for respective clocks described by
-                     clock-names.
-
-- #address-cells   : must be 1.
-
-- #size-cells      : must be 1.
-
-- #iommu-cells     : Must be 1.  Index identifies the context-bank #.
-
-- ranges           : Base address and size of the iommu context banks.
-
-- qcom,iommu-secure-id  : secure-id.
-
-- List of sub-nodes, one per translation context bank.  Each sub-node
-  has the following required properties:
-
-  - compatible     : Should be one of:
-        - "qcom,msm-iommu-v1-ns"  : non-secure context bank
-        - "qcom,msm-iommu-v1-sec" : secure context bank
-  - reg            : Base address and size of context bank within the iommu
-  - interrupts     : The context fault irq.
-
-** Optional properties:
-
-- reg              : Base address and size of the SMMU local base, should
-                     be only specified if the iommu requires configuration
-                     for routing of context bank irq's to secure vs non-
-                     secure lines.  (Ie. if the iommu contains secure

+description:
+  The BD2606 MVV is a programmable LED controller connected via I2C that can
+  drive 6 separate lines. Each of them can be individually switched on and off,
+  but the brightness setting is shared between pairs of them.

+description:
+  The S5C73M3 camera ISP supports MIPI CSI-2 and parallel (ITU-R BT.656)
+  video data busses. The I2C bus is the main control bus and additionally the
+  SPI bus is used, mostly for transferring the firmware to and from the
+  device. Two slave device nodes corresponding to these control bus
+  interfaces are required and should be placed under respective bus
+  controller nodes.

-Samsung S5P/Exynos SoC Camera Subsystem (FIMC)
-----------------------------------------------
-
-The S5P/Exynos SoC Camera subsystem comprises of multiple sub-devices
-represented by separate device tree nodes. Currently this includes: FIMC (in
-the S5P SoCs series known as CAMIF), MIPI CSIS, FIMC-LITE and FIMC-IS (ISP).
-
-The sub-subdevices are defined as child nodes of the common 'camera' node which
-also includes common properties of the whole subsystem not really specific to
-any single sub-device, like common camera port pins or the CAMCLK clock outputs
-for external image sensors attached to an SoC.
-
-Common 'camera' node
---------------------
-
-Required properties:
-
-- compatible: must be "samsung,fimc", "simple-bus"
-- clocks: list of clock specifiers, corresponding to entries in
-  the clock-names property;
-- clock-names : must contain "sclk_cam0", "sclk_cam1", "pxl_async0",
-  "pxl_async1" entries, matching entries in the clocks property.
-
-- #clock-cells: from the common clock bindings (../clock/clock-bindings.txt),
-  must be 1. A clock provider is associated with the 'camera' node and it should
-  be referenced by external sensors that use clocks provided by the SoC on
-  CAM_*_CLKOUT pins. The clock specifier cell stores an index of a clock.
-  The indices are 0, 1 for CAM_A_CLKOUT, CAM_B_CLKOUT clocks respectively.
-
-- clock-output-names: from the common clock bindings, should contain names of
-  clocks registered by the camera subsystem corresponding to CAM_A_CLKOUT,
-  CAM_B_CLKOUT output clocks respectively.
-
-The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
-to define a required pinctrl state named "default" and optional pinctrl states:
-"idle", "active-a", active-b". These optional states can be used to switch the
-camera port pinmux at runtime. The "idle" state should configure both the camera
-ports A and B into high impedance state, especially the CAMCLK clock output
-should be inactive. For the "active-a" state the camera port A must be activated
-and the port B deactivated and for the state "active-b" it should be the other
-way around.
-
-The 'camera' node must include at least one 'fimc' child node.
-
-
-'fimc' device nodes
--------------------
-
-Required properties:
-
-- compatible: "samsung,s5pv210-fimc" for S5PV210, "samsung,exynos4210-fimc"
-  for Exynos4210 and "samsung,exynos4212-fimc" for Exynos4x12 SoCs;
-- reg: physical base address and length of the registers set for the device;
-- interrupts: should contain FIMC interrupt;
-- clocks: list of clock specifiers, must contain an entry for each required
-  entry in clock-names;
-- clock-names: must contain "fimc", "sclk_fimc" entries.
-- samsung,pix-limits: an array of maximum supported image sizes in pixels, for
-  details refer to Table 2-1 in the S5PV210 SoC User Manual; The meaning of
-  each cell is as follows:
-  0 - scaler input horizontal size,
-  1 - input horizontal size for the scaler bypassed,
-  2 - REAL_WIDTH without input rotation,
-  3 - REAL_HEIGHT with input rotation,
-- samsung,sysreg: a phandle to the SYSREG node.
-
-Each FIMC device should have an alias in the aliases node, in the form of
-fimc<n>, where <n> is an integer specifying the IP block instance.
-
-Optional properties:
-
-- clock-frequency: maximum FIMC local clock (LCLK) frequency;
-- samsung,min-pix-sizes: an array specyfing minimum image size in pixels at
-  the FIMC input and output DMA, in the first and second cell respectively.
-  Default value when this property is not present is <16 16>;
-- samsung,min-pix-alignment: minimum supported image height alignment (first
-  cell) and the horizontal image offset (second cell). The values are in pixels
-  and default to <2 1> when this property is not present;
-- samsung,mainscaler-ext: a boolean property indicating whether the FIMC IP
-  supports extended image size and has CIEXTEN register;
-- samsung,rotators: a bitmask specifying whether this IP has the input and
-  the output rotator. Bits 4 and 0 correspond to input and output rotator
-  respectively. If a rotator is present its corresponding bit should be set.
-  Default value when this property is not specified is 0x11.
-- samsung,cam-if: a bolean property indicating whether the IP block includes
-  the camera input interface.
-- samsung,isp-wb: this property must be present if the IP block has the ISP
-  writeback input.
-- samsung,lcd-wb: this property must be present if the IP block has the LCD
-  writeback input.
-
-
-'parallel-ports' node
----------------------
-
-This node should contain child 'port' nodes specifying active parallel video
-input ports. It includes camera A and camera B inputs. 'reg' property in the
-port nodes specifies data input - 1, 2 indicates input A, B respectively.
-
-Optional properties
-
-- samsung,camclk-out (deprecated) : specifies clock output for remote sensor,
-  0 - CAM_A_CLKOUT, 1 - CAM_B_CLKOUT;
-
-Image sensor nodes
-------------------
-
-The sensor device nodes should be added to their control bus controller (e.g.
-I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
-using the common video interfaces bindings, defined in video-interfaces.txt.

+description:
+  This binding describes UART-attached NXP bluetooth chips. These chips
+  are dual-radio chips supporting WiFi and Bluetooth. The bluetooth
+  works on standard H4 protocol over 4-wire UART. The RTS and CTS lines
+  are used during FW download. To enable power save mode, the host
+  asserts break signal over UART-TX line to put the chip into power save
+  state. De-asserting break wakes up the BT chip.

-Amlogic Meson AXG DWC PCIE SoC controller
-
-Amlogic Meson PCIe host controller is based on the Synopsys DesignWare PCI core.
-It shares common functions with the PCIe DesignWare core driver and
-inherits common properties defined in
-Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml.
-
-Additional properties are described here:
-
-Required properties:
-- compatible:
-	should contain :
-	- "amlogic,axg-pcie" for AXG SoC Family
-	- "amlogic,g12a-pcie" for G12A SoC Family
-	to identify the core.
-- reg:
-	should contain the configuration address space.
-- reg-names: Must be
-	- "elbi"	External local bus interface registers
-	- "cfg"		Meson specific registers
-	- "config"	PCIe configuration space
-- reset-gpios: The GPIO to generate PCIe PERST# assert and deassert signal.
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Must include the following entries:
-	- "pclk"       PCIe GEN 100M PLL clock
-	- "port"       PCIe_x(A or B) RC clock gate
-	- "general"    PCIe Phy clock
-- resets: phandle to the reset lines.
-- reset-names: must contain "port" and "apb"
-       - "port"        Port A or B reset
-       - "apb"         Share APB reset
-- phys: should contain a phandle to the PCIE phy
-- phy-names: must contain "pcie"
-
-- device_type:
-	should be "pci". As specified in snps,dw-pcie.yaml
-

+  MediaTek MT76X8 pin controller for MT7628 and MT7688 SoCs.
   The pin controller can only set the muxing of pin groups. Muxing individual
   pins is not supported. There is no pinconf support.

-
-=== GPIO sub-nodes ===
-
-The GPIO bank for the controller is represented as a sub-node and it acts as a
-GPIO controller.
-
-Required properties for sub-nodes are:
- - reg: should contain a list of address and size, one tuple for each entry
-   in reg-names.
- - reg-names: an array of strings describing the "reg" entries.
-   Must contain "mux" and "gpio".
-   May contain "pull", "pull-enable" and "ds" when appropriate.
- - gpio-controller: identifies the node as a gpio controller
- - #gpio-cells: must be 2
-
-=== Other sub-nodes ===
-
-Child nodes without the "gpio-controller" represent some desired
-configuration for a pin or a group. Those nodes can be pinmux nodes or
-configuration nodes.
-
-Required properties for pinmux nodes are:
- - groups: a list of pinmux groups. The list of all available groups
-   depends on the SoC and can be found in driver sources.
- - function: the name of a function to activate for the specified set
-   of groups. The list of all available functions depends on the SoC
-   and can be found in driver sources.
-
-Required properties for configuration nodes:
- - pins: a list of pin names
-
-Configuration nodes support the following generic properties, as
-described in file pinctrl-bindings.txt:
- - "bias-disable"
- - "bias-pull-up"
- - "bias-pull-down"
- - "output-enable"
- - "output-disable"
- - "output-low"
- - "output-high"
-
-Optional properties :
- - drive-strength-microamp: Drive strength for the specified pins in uA.
-			    This property is only valid for G12A and newer.
-
-=== Example ===

+  Basic battery capacity meter, which only reports basic battery data

+  The voltage is expected to be measured between the battery terminals
+  and mandatory. The optional current/power channel is expected to
+  monitor the current/power flowing out of the battery. Last but not
+  least the temperature channel is supposed to measure the battery
+  temperature.

+description: |
+  RT4803 is a boost regulator that's designed to provide the minimum output
+  voltage, even if the input voltage is lower than the required voltage. It
+  supports boost and auto bypass mode that depends on the difference between the
+  input and output voltage. If the input is lower than the output, mode will
+  transform to boost mode. Otherwise, turn on bypass switch to enter bypass mode.

+
+description: |
+  The RT5739 is a step-down switching buck converter that can deliver the
+  programmable output voltage from 300mV to 1300mV with wide input voltage
+  supply of 2.5V to 5.5V. It can provide up to 3.5A continuous current
+  capability at over 80% high efficiency.

-Amlogic Internal Clock Measurer
-===============================
-
-The Amlogic SoCs contains an IP to measure the internal clocks.
-The precision is multiple of MHz, useful to debug the clock states.
-
-Required properties:
-- compatible: Shall contain one of the following :
-			"amlogic,meson-gx-clk-measure" for GX SoCs
-			"amlogic,meson8-clk-measure" for Meson8 SoCs
-			"amlogic,meson8b-clk-measure" for Meson8b SoCs
-			"amlogic,meson-axg-clk-measure" for AXG SoCs
-			"amlogic,meson-g12a-clk-measure" for G12a SoCs
-			"amlogic,meson-sm1-clk-measure" for SM1 SoCs
-- reg: base address and size of the Clock Measurer register space.
-
-Example:
-	clock-measure@8758 {
-		compatible = "amlogic,meson-gx-clk-measure";
-		reg = <0x0 0x8758 0x0 0x10>;

+
+description: |
+  This hardware block consists of eight 16-bit timer channels and one
+  32- bit timer channel. It supports the following specifications:
+    - Pulse input/output: 28 lines max.
+    - Pulse input 3 lines
+    - Count clock 11 clocks for each channel (14 clocks for MTU0, 12 clocks
+      for MTU2, and 10 clocks for MTU5, four clocks for MTU1-MTU2 combination
+      (when LWA = 1))
+    - Operating frequency Up to 100 MHz
+    - Available operations [MTU0 to MTU4, MTU6, MTU7, and MTU8]
+        - Waveform output on compare match
+        - Input capture function (noise filter setting available)
+        - Counter-clearing operation
+        - Simultaneous writing to multiple timer counters (TCNT)
+          (excluding MTU8).
+        - Simultaneous clearing on compare match or input capture
+          (excluding MTU8).
+        - Simultaneous input and output to registers in synchronization with
+          counter operations           (excluding MTU8).
+        - Up to 12-phase PWM output in combination with synchronous operation
+          (excluding MTU8)
+    - [MTU0 MTU3, MTU4, MTU6, MTU7, and MTU8]
+        - Buffer operation specifiable
+    - [MTU1, MTU2]
+        - Phase counting mode can be specified independently
+        - 32-bit phase counting mode can be specified for interlocked operation
+          of MTU1 and MTU2 (when TMDR3.LWA = 1)
+        - Cascade connection operation available
+    - [MTU3, MTU4, MTU6, and MTU7]
+        - Through interlocked operation of MTU3/4 and MTU6/7, the positive and
+          negative signals in six phases (12 phases in total) can be output in
+          complementary PWM and reset-synchronized PWM operation.
+        - In complementary PWM mode, values can be transferred from buffer
+          registers to temporary registers at crests and troughs of the timer-
+          counter values or when the buffer registers (TGRD registers in MTU4
+          and MTU7) are written to.
+        - Double-buffering selectable in complementary PWM mode.
+    - [MTU3 and MTU4]
+        - Through interlocking with MTU0, a mode for driving AC synchronous
+          motors (brushless DC motors) by using complementary PWM output and
+          reset-synchronized PWM output is settable and allows the selection
+          of two types of waveform output (chopping or level).
+    - [MTU5]
+        - Capable of operation as a dead-time compensation counter.
+    - [MTU0/MTU5, MTU1, MTU2, and MTU8]
+        - 32-bit phase counting mode specifiable by combining MTU1 and MTU2 and
+          through interlocked operation with MTU0/MTU5 and MTU8.
+    - Interrupt-skipping function
+        - In complementary PWM mode, interrupts on crests and troughs of counter
+          values and triggers to start conversion by the A/D converter can be
+          skipped.
+    - Interrupt sources: 43 sources.
+    - Buffer operation:
+        - Automatic transfer of register data (transfer from the buffer
+          register to the timer register).
+    - Trigger generation
+        - A/D converter start triggers can be generated
+        - A/D converter start request delaying function enables A/D converter
+          to be started with any desired timing and to be synchronized with
+          PWM output.
+    - Low power consumption function
+        - The MTU3a can be placed in the module-stop state.
+
+    There are two phase counting modes. 16-bit phase counting mode in which
+    MTU1 and MTU2 operate independently, and cascade connection 32-bit phase
+    counting mode in which MTU1 and MTU2 are cascaded.
+
+    In phase counting mode, the phase difference between two external input
+    clocks is detected and the corresponding TCNT is incremented or
+    decremented.
+    The below counters are supported
+      count0 - MTU1 16-bit phase counting
+      count1 - MTU2 16-bit phase counting
+      count2 - MTU1+ MTU2 32-bit phase counting
+
+    The module supports PWM mode{1,2}, Reset-synchronized PWM mode and
+    complementary PWM mode{1,2,3}.
+
+    In complementary PWM mode, six positive-phase and six negative-phase PWM
+    waveforms (12 phases in total) with dead time can be output by
+    combining MTU{3,4} and MTU{6,7}.
+
+    The below pwm channels are supported in pwm mode 1.
+      pwm0  - MTU0.MTIOC0A PWM mode 1
+      pwm1  - MTU0.MTIOC0C PWM mode 1
+      pwm2  - MTU1.MTIOC1A PWM mode 1
+      pwm3  - MTU2.MTIOC2A PWM mode 1
+      pwm4  - MTU3.MTIOC3A PWM mode 1
+      pwm5  - MTU3.MTIOC3C PWM mode 1
+      pwm6  - MTU4.MTIOC4A PWM mode 1
+      pwm7  - MTU4.MTIOC4C PWM mode 1
+      pwm8  - MTU6.MTIOC6A PWM mode 1
+      pwm9  - MTU6.MTIOC6C PWM mode 1
+      pwm10 - MTU7.MTIOC7A PWM mode 1
+      pwm11 - MTU7.MTIOC7C PWM mode 1

-* USB2 ChipIdea USB controller for ci13xxx
-
-Required properties:
-- compatible: should be one of:

-	"fsl,imx27-usb"
-	"fsl,imx28-usb"
-	"fsl,imx6q-usb"

-	"nvidia,tegra20-udc"
-	"nvidia,tegra30-udc"
-	"nvidia,tegra114-udc"
-	"nvidia,tegra124-udc"
-- reg: base address and length of the registers
-- interrupts: interrupt for the USB controller
-
-Recommended properies:
-- phy_type: the type of the phy connected to the core. Should be one
-  of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
-  property the PORTSC register won't be touched.
-- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
-
-Deprecated properties:
-- usb-phy:      phandle for the PHY device. Use "phys" instead.
-- fsl,usbphy: phandle of usb phy that connects to the port. Use "phys" instead.
-
-Optional properties:
-- clocks: reference to the USB clock
-- phys: reference to the USB PHY
-- phy-names: should be "usb-phy"
-- vbus-supply: reference to the VBUS regulator
-- maximum-speed: limit the maximum connection speed to "full-speed".
-- tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts
-- itc-setting: interrupt threshold control register control, the setting
-  should be aligned with ITC bits at register USBCMD.
-- ahb-burst-config: it is vendor dependent, the required value should be
-  aligned with AHBBRST at SBUSCFG, the range is from 0x0 to 0x7. This
-  property is used to change AHB burst configuration, check the chipidea
-  spec for meaning of each value. If this property is not existed, it
-  will use the reset value.
-- tx-burst-size-dword: it is vendor dependent, the tx burst size in dword
-  (4 bytes), This register represents the maximum length of a the burst
-  in 32-bit words while moving data from system memory to the USB
-  bus, the value of this property will only take effect if property
-  "ahb-burst-config" is set to 0, if this property is missing the reset
-  default of the hardware implementation will be used.
-- rx-burst-size-dword: it is vendor dependent, the rx burst size in dword
-  (4 bytes), This register represents the maximum length of a the burst
-  in 32-bit words while moving data from the USB bus to system memory,
-  the value of this property will only take effect if property
-  "ahb-burst-config" is set to 0, if this property is missing the reset
-  default of the hardware implementation will be used.
-- extcon: phandles to external connector devices. First phandle should point to
-  external connector, which provide "USB" cable events, the second should point
-  to external connector device, which provide "USB-HOST" cable events. If one
-  of the external connector devices is not required, empty <0> phandle should
-  be specified.
-- phy-clkgate-delay-us: the delay time (us) between putting the PHY into
-  low power mode and gating the PHY clock.
-- non-zero-ttctrl-ttha: after setting this property, the value of register
-  ttctrl.ttha will be 0x7f; if not, the value will be 0x0, this is the default
-  value. It needs to be very carefully for setting this property, it is
-  recommended that consult with your IC engineer before setting this value.
-  On the most of chipidea platforms, the "usage_tt" flag at RTL is 0, so this
-  property only affects siTD.
-  If this property is not set, the max packet size is 1023 bytes, and if
-  the total of packet size for pervious transactions are more than 256 bytes,
-  it can't accept any transactions within this frame. The use case is single
-  transaction, but higher frame rate.
-  If this property is set, the max packet size is 188 bytes, it can handle
-  more transactions than above case, it can accept transactions until it
-  considers the left room size within frame is less than 188 bytes, software
-  needs to make sure it does not send more than 90%
-  maximum_periodic_data_per_frame. The use case is multiple transactions, but
-  less frame rate.
-- mux-controls: The mux control for toggling host/device output of this
-  controller. It's expected that a mux state of 0 indicates device mode and a
-  mux state of 1 indicates host mode.
-- mux-control-names: Shall be "usb_switch" if mux-controls is specified.
-- pinctrl-names: Names for optional pin modes in "default", "host", "device".
-  In case of HSIC-mode, "idle" and "active" pin modes are mandatory. In this
-  case, the "idle" state needs to pull down the data and strobe pin
-  and the "active" state needs to pull up the strobe pin.
-- pinctrl-n: alternate pin modes
-
-i.mx specific properties
-- fsl,usbmisc: phandler of non-core register device, with one
-  argument that indicate usb controller index
-- disable-over-current: disable over current detect
-- over-current-active-low: over current signal polarity is active low.
-- over-current-active-high: over current signal polarity is active high.
-  It's recommended to specify the over current polarity.
-- power-active-high: power signal polarity is active high
-- external-vbus-divider: enables off-chip resistor divider for Vbus
-- samsung,picophy-pre-emp-curr-control: HS Transmitter Pre-Emphasis Current
-  Control. This signal controls the amount of current sourced to the
-  USB_OTG*_DP and USB_OTG*_DN pins after a J-to-K or K-to-J transition.
-  The range is from 0x0 to 0x3, the default value is 0x1.
-  Details can refer to TXPREEMPAMPTUNE0 bits of USBNC_n_PHY_CFG1.
-- samsung,picophy-dc-vol-level-adjust: HS DC Voltage Level Adjustment.
-  Adjust the high-speed transmitter DC level voltage.
-  The range is from 0x0 to 0xf, the default value is 0x3.
-  Details can refer to TXVREFTUNE0 bits of USBNC_n_PHY_CFG1.

+description:
+  The JH7100 and JH7110 watchdog both are 32 bit counters. JH7100 watchdog
+  has only one timeout phase and reboots. And JH7110 watchdog has two
+  timeout phases. At the first phase, the signal of watchdog interrupt
+  output(WDOGINT) will rise when counter is 0. The counter will reload
+  the timeout value. And then, if counter decreases to 0 again and WDOGINT
+  isn't cleared, the watchdog will reset the system unless the watchdog
+  reset is disabled.

+================
+
+NVMEM layouts are yet another mechanism to create cells. With the device
+tree binding it is possible to specify simple cells by using an offset
+and a length. Sometimes, the cells doesn't have a static offset, but
+the content is still well defined, e.g. tag-length-values. In this case,
+the NVMEM device content has to be first parsed and the cells need to
+be added accordingly. Layouts let you read the content of the NVMEM device
+and let you add cells dynamically.
+
+Another use case for layouts is the post processing of cells. With layouts,
+it is possible to associate a custom post processing hook to a cell. It
+even possible to add this hook to cells not created by the layout itself.

 Idmappings when creating filesystem objects
 -------------------------------------------
 
@@ -623,42 +627,105 @@ privileged users in the initial user namespace.
 However, it is perfectly possible to combine idmapped mounts with filesystems
 mountable inside user namespaces. We will touch on this further below.
 
+Filesystem types vs idmapped mount types
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+With the introduction of idmapped mounts we need to distinguish between
+filesystem ownership and mount ownership of a VFS object such as an inode. The
+owner of a inode might be different when looked at from a filesystem
+perspective than when looked at from an idmapped mount. Such fundamental
+conceptual distinctions should almost always be clearly expressed in the code.
+So, to distinguish idmapped mount ownership from filesystem ownership separate
+types have been introduced.
+
+If a uid or gid has been generated using the filesystem or caller's idmapping
+then we will use the ``kuid_t`` and ``kgid_t`` types. However, if a uid or gid
+has been generated using a mount idmapping then we will be using the dedicated
+``vfsuid_t`` and ``vfsgid_t`` types.
+
+All VFS helpers that generate or take uids and gids as arguments use the
+``vfsuid_t`` and ``vfsgid_t`` types and we will be able to rely on the compiler
+to catch errors that originate from conflating filesystem and VFS uids and gids.
+
+The ``vfsuid_t`` and ``vfsgid_t`` types are often mapped from and to ``kuid_t``
+and ``kgid_t`` types similar how ``kuid_t`` and ``kgid_t`` types are mapped
+from and to ``uid_t`` and ``gid_t`` types::
+
+ uid_t <--> kuid_t <--> vfsuid_t
+ gid_t <--> kgid_t <--> vfsgid_t
+
+Whenever we report ownership based on a ``vfsuid_t`` or ``vfsgid_t`` type,
+e.g., during ``stat()``, or store ownership information in a shared VFS object
+based on a ``vfsuid_t`` or ``vfsgid_t`` type, e.g., during ``chown()`` we can
+use the ``vfsuid_into_kuid()`` and ``vfsgid_into_kgid()`` helpers.
+
+To illustrate why this helper currently exists, consider what happens when we
+change ownership of an inode from an idmapped mount. After we generated
+a ``vfsuid_t`` or ``vfsgid_t`` based on the mount idmapping we later commit to
+this ``vfsuid_t`` or ``vfsgid_t`` to become the new filesytem wide ownership.
+Thus, we are turning the ``vfsuid_t`` or ``vfsgid_t`` into a global ``kuid_t``
+or ``kgid_t``. And this can be done by using ``vfsuid_into_kuid()`` and
+``vfsgid_into_kgid()``.
+
+Note, whenever a shared VFS object, e.g., a cached ``struct inode`` or a cached
+``struct posix_acl``, stores ownership information a filesystem or "global"
+``kuid_t`` and ``kgid_t`` must be used. Ownership expressed via ``vfsuid_t``
+and ``vfsgid_t`` is specific to an idmapped mount.
+
+We already noted that ``vfsuid_t`` and ``vfsgid_t`` types are generated based
+on mount idmappings whereas ``kuid_t`` and ``kgid_t`` types are generated based
+on filesystem idmappings. To prevent abusing filesystem idmappings to generate
+``vfsuid_t`` or ``vfsgid_t`` types or mount idmappings to generate ``kuid_t``
+or ``kgid_t`` types filesystem idmappings and mount idmappings are different
+types as well.
+
+All helpers that map to or from ``vfsuid_t`` and ``vfsgid_t`` types require
+a mount idmapping to be passed which is of type ``struct mnt_idmap``. Passing
+a filesystem or caller idmapping will cause a compilation error.
+
+Similar to how we prefix all userspace ids in this document with ``u`` and all
+kernel ids with ``k`` we will prefix all VFS ids with ``v``. So a mount
+idmapping will be written as: ``u0:v10000:r10000``.

-
-If you compare it to ramfs (which was the template to create tmpfs)
-you gain swapping and limit checking. Another similar thing is the RAM

+tmpfs extends ramfs with a few userspace configurable options listed and
+explained further below, some of which can be reconfigured dynamically on the
+fly using a remount ('mount -o remount ...') of the filesystem. A tmpfs
+filesystem can be resized but it cannot be resized to a size below its current
+usage. tmpfs also supports POSIX ACLs, and extended attributes for the
+trusted.* and security.* namespaces. ramfs does not use swap and you cannot
+modify any parameter for a ramfs filesystem. The size limit of a ramfs
+filesystem is how much memory you have available, and so care must be taken if
+used so to not run out of memory.
+
+An alternative to tmpfs and ramfs is to use brd to create RAM disks
+(/dev/ram*), which allows you to simulate a block device disk in physical RAM.
+To write data you would just then need to create an regular filesystem on top
+this ramdisk. As with ramfs, brd ramdisks cannot swap. brd ramdisks are also
+configured in size at initialization and you cannot dynamically resize them.
+Contrary to brd ramdisks, tmpfs has its own filesystem, it does not rely on the
+block layer at all.

+XFS Online Fsck Design
+======================
+
+This document captures the design of the online filesystem check feature for
+XFS.
+The purpose of this document is threefold:
+
+- To help kernel distributors understand exactly what the XFS online fsck
+  feature is, and issues about which they should be aware.
+
+- To help people reading the code to familiarize themselves with the relevant
+  concepts and design points before they start digging into the code.
+
+- To help developers maintaining the system by capturing the reasons
+  supporting higher level decision making.
+
+As the online fsck code is merged, the links in this document to topic branches
+will be replaced with links to code.
+
+This document is licensed under the terms of the GNU Public License, v2.
+The primary author is Darrick J. Wong.
+
+This design document is split into seven parts.
+Part 1 defines what fsck tools are and the motivations for writing a new one.
+Parts 2 and 3 present a high level overview of how online fsck process works
+and how it is tested to ensure correct functionality.
+Part 4 discusses the user interface and the intended usage modes of the new
+program.
+Parts 5 and 6 show off the high level components and how they fit together, and
+then present case studies of how each repair function actually works.
+Part 7 sums up what has been discussed so far and speculates about what else
+might be built atop online fsck.

+
+1. What is a Filesystem Check?
+==============================
+
+A Unix filesystem has four main responsibilities:
+
+- Provide a hierarchy of names through which application programs can associate
+  arbitrary blobs of data for any length of time,
+
+- Virtualize physical storage media across those names, and
+
+- Retrieve the named data blobs at any time.
+
+- Examine resource usage.
+
+Metadata directly supporting these functions (e.g. files, directories, space
+mappings) are sometimes called primary metadata.
+Secondary metadata (e.g. reverse mapping and directory parent pointers) support
+operations internal to the filesystem, such as internal consistency checking
+and reorganization.
+Summary metadata, as the name implies, condense information contained in
+primary metadata for performance reasons.
+
+The filesystem check (fsck) tool examines all the metadata in a filesystem
+to look for errors.
+In addition to looking for obvious metadata corruptions, fsck also
+cross-references different types of metadata records with each other to look
+for inconsistencies.
+People do not like losing data, so most fsck tools also contains some ability
+to correct any problems found.
+As a word of caution -- the primary goal of most Linux fsck tools is to restore
+the filesystem metadata to a consistent state, not to maximize the data
+recovered.
+That precedent will not be challenged here.
+
+Filesystems of the 20th century generally lacked any redundancy in the ondisk
+format, which means that fsck can only respond to errors by erasing files until
+errors are no longer detected.
+More recent filesystem designs contain enough redundancy in their metadata that
+it is now possible to regenerate data structures when non-catastrophic errors
+occur; this capability aids both strategies.

+
+Existing Tools
+--------------
+
+The online fsck tool described here will be the third tool in the history of
+XFS (on Linux) to check and repair filesystems.
+Two programs precede it:
+
+The first program, ``xfs_check``, was created as part of the XFS debugger
+(``xfs_db``) and can only be used with unmounted filesystems.
+It walks all metadata in the filesystem looking for inconsistencies in the
+metadata, though it lacks any ability to repair what it finds.
+Due to its high memory requirements and inability to repair things, this
+program is now deprecated and will not be discussed further.
+
+The second program, ``xfs_repair``, was created to be faster and more robust
+than the first program.
+Like its predecessor, it can only be used with unmounted filesystems.
+It uses extent-based in-memory data structures to reduce memory consumption,
+and tries to schedule readahead IO appropriately to reduce I/O waiting time
+while it scans the metadata of the entire filesystem.
+The most important feature of this tool is its ability to respond to
+inconsistencies in file metadata and directory tree by erasing things as needed
+to eliminate problems.
+Space usage metadata are rebuilt from the observed file metadata.
+
+Problem Statement
+-----------------
+
+The current XFS tools leave several problems unsolved:
+
+1. **User programs** suddenly **lose access** to the filesystem when unexpected
+   shutdowns occur as a result of silent corruptions in the metadata.
+   These occur **unpredictably** and often without warning.
+
+2. **Users** experience a **total loss of service** during the recovery period
+   after an **unexpected shutdown** occurs.
+
+3. **Users** experience a **total loss of service** if the filesystem is taken
+   offline to **look for problems** proactively.
+
+4. **Data owners** cannot **check the integrity** of their stored data without
+   reading all of it.
+   This may expose them to substantial billing costs when a linear media scan
+   performed by the storage system administrator might suffice.
+
+5. **System administrators** cannot **schedule** a maintenance window to deal
+   with corruptions if they **lack the means** to assess filesystem health
+   while the filesystem is online.
+
+6. **Fleet monitoring tools** cannot **automate periodic checks** of filesystem
+   health when doing so requires **manual intervention** and downtime.
+
+7. **Users** can be tricked into **doing things they do not desire** when
+   malicious actors **exploit quirks of Unicode** to place misleading names
+   in directories.
+
+Given this definition of the problems to be solved and the actors who would
+benefit, the proposed solution is a third fsck tool that acts on a running
+filesystem.
+
+This new third program has three components: an in-kernel facility to check
+metadata, an in-kernel facility to repair metadata, and a userspace driver
+program to drive fsck activity on a live filesystem.
+``xfs_scrub`` is the name of the driver program.
+The rest of this document presents the goals and use cases of the new fsck
+tool, describes its major design points in connection to those goals, and
+discusses the similarities and differences with existing tools.
+

+| **Note**:                                                                |
++--------------------------------------------------------------------------+
+| Throughout this document, the existing offline fsck tool can also be     |
+| referred to by its current name "``xfs_repair``".                        |
+| The userspace driver program for the new online fsck tool can be         |
+| referred to as "``xfs_scrub``".                                          |
+| The kernel portion of online fsck that validates metadata is called      |
+| "online scrub", and portion of the kernel that fixes metadata is called  |
+| "online repair".                                                         |
++--------------------------------------------------------------------------+
+
+The naming hierarchy is broken up into objects known as directories and files
+and the physical space is split into pieces known as allocation groups.
+Sharding enables better performance on highly parallel systems and helps to
+contain the damage when corruptions occur.
+The division of the filesystem into principal objects (allocation groups and
+inodes) means that there are ample opportunities to perform targeted checks and
+repairs on a subset of the filesystem.
+
+While this is going on, other parts continue processing IO requests.
+Even if a piece of filesystem metadata can only be regenerated by scanning the
+entire system, the scan can still be done in the background while other file
+operations continue.
+
+In summary, online fsck takes advantage of resource sharding and redundant
+metadata to enable targeted checking and repair operations while the system
+is running.
+This capability will be coupled to automatic system management so that
+autonomous self-healing of XFS maximizes service availability.
+
+2. Theory of Operation
+======================
+
+Because it is necessary for online fsck to lock and scan live metadata objects,
+online fsck consists of three separate code components.
+The first is the userspace driver program ``xfs_scrub``, which is responsible
+for identifying individual metadata items, scheduling work items for them,
+reacting to the outcomes appropriately, and reporting results to the system
+administrator.
+The second and third are in the kernel, which implements functions to check
+and repair each type of online fsck work item.
+
++------------------------------------------------------------------+
+| **Note**:                                                        |
++------------------------------------------------------------------+
+| For brevity, this document shortens the phrase "online fsck work |
+| item" to "scrub item".                                           |
++------------------------------------------------------------------+
+
+Scrub item types are delineated in a manner consistent with the Unix design
+philosophy, which is to say that each item should handle one aspect of a
+metadata structure, and handle it well.
+
+Scope
+-----
+
+In principle, online fsck should be able to check and to repair everything that
+the offline fsck program can handle.
+However, online fsck cannot be running 100% of the time, which means that
+latent errors may creep in after a scrub completes.
+If these errors cause the next mount to fail, offline fsck is the only
+solution.
+This limitation means that maintenance of the offline fsck tool will continue.
+A second limitation of online fsck is that it must follow the same resource
+sharing and lock acquisition rules as the regular filesystem.
+This means that scrub cannot take *any* shortcuts to save time, because doing
+so could lead to concurrency problems.
+In other words, online fsck is not a complete replacement for offline fsck, and
+a complete run of online fsck may take longer than online fsck.
+However, both of these limitations are acceptable tradeoffs to satisfy the
+different motivations of online fsck, which are to **minimize system downtime**
+and to **increase predictability of operation**.
+
+.. _scrubphases:
+
+Phases of Work
+--------------
+
+The userspace driver program ``xfs_scrub`` splits the work of checking and
+repairing an entire filesystem into seven phases.
+Each phase concentrates on checking specific types of scrub items and depends
+on the success of all previous phases.
+The seven phases are as follows:
+
+1. Collect geometry information about the mounted filesystem and computer,
+   discover the online fsck capabilities of the kernel, and open the
+   underlying storage devices.
+
+2. Check allocation group metadata, all realtime volume metadata, and all quota
+   files.
+   Each metadata structure is scheduled as a separate scrub item.
+   If corruption is found in the inode header or inode btree and ``xfs_scrub``
+   is permitted to perform repairs, then those scrub items are repaired to
+   prepare for phase 3.
+   Repairs are implemented by using the information in the scrub item to
+   resubmit the kernel scrub call with the repair flag enabled; this is
+   discussed in the next section.
+   Optimizations and all other repairs are deferred to phase 4.
+
+3. Check all metadata of every file in the filesystem.
+   Each metadata structure is also scheduled as a separate scrub item.
+   If repairs are needed and ``xfs_scrub`` is permitted to perform repairs,
+   and there were no problems detected during phase 2, then those scrub items
+   are repaired immediately.
+   Optimizations, deferred repairs, and unsuccessful repairs are deferred to
+   phase 4.
+
+4. All remaining repairs and scheduled optimizations are performed during this
+   phase, if the caller permits them.
+   Before starting repairs, the summary counters are checked and any necessary
+   repairs are performed so that subsequent repairs will not fail the resource
+   reservation step due to wildly incorrect summary counters.
+   Unsuccesful repairs are requeued as long as forward progress on repairs is
+   made somewhere in the filesystem.
+   Free space in the filesystem is trimmed at the end of phase 4 if the
+   filesystem is clean.
+
+5. By the start of this phase, all primary and secondary filesystem metadata
+   must be correct.
+   Summary counters such as the free space counts and quota resource counts
+   are checked and corrected.
+   Directory entry names and extended attribute names are checked for
+   suspicious entries such as control characters or confusing Unicode sequences
+   appearing in names.
+
+6. If the caller asks for a media scan, read all allocated and written data
+   file extents in the filesystem.
+   The ability to use hardware-assisted data file integrity checking is new
+   to online fsck; neither of the previous tools have this capability.
+   If media errors occur, they will be mapped to the owning files and reported.
+
+7. Re-check the summary counters and presents the caller with a summary of
+   space usage and file counts.
+
+This allocation of responsibilities will be :ref:`revisited <scrubcheck>`
+later in this document.
+
+Steps for Each Scrub Item
+-------------------------
+
+The kernel scrub code uses a three-step strategy for checking and repairing
+the one aspect of a metadata object represented by a scrub item:
+
+1. The scrub item of interest is checked for corruptions; opportunities for
+   optimization; and for values that are directly controlled by the system
+   administrator but look suspicious.
+   If the item is not corrupt or does not need optimization, resource are
+   released and the positive scan results are returned to userspace.
+   If the item is corrupt or could be optimized but the caller does not permit
+   this, resources are released and the negative scan results are returned to
+   userspace.
+   Otherwise, the kernel moves on to the second step.
+
+2. The repair function is called to rebuild the data structure.
+   Repair functions generally choose rebuild a structure from other metadata
+   rather than try to salvage the existing structure.
+   If the repair fails, the scan results from the first step are returned to
+   userspace.
+   Otherwise, the kernel moves on to the third step.
+
+3. In the third step, the kernel runs the same checks over the new metadata
+   item to assess the efficacy of the repairs.
+   The results of the reassessment are returned to userspace.
+
+Classification of Metadata
+--------------------------
+
+Each type of metadata object (and therefore each type of scrub item) is
+classified as follows:
+
+Primary Metadata
+````````````````
+
+Metadata structures in this category should be most familiar to filesystem
+users either because they are directly created by the user or they index
+objects created by the user
+Most filesystem objects fall into this class:
+
+- Free space and reference count information
+
+- Inode records and indexes
+
+- Storage mapping information for file data
+
+- Directories
+
+- Extended attributes
+
+- Symbolic links
+
+- Quota limits
+
+Scrub obeys the same rules as regular filesystem accesses for resource and lock
+acquisition.
+
+Primary metadata objects are the simplest for scrub to process.
+The principal filesystem object (either an allocation group or an inode) that
+owns the item being scrubbed is locked to guard against concurrent updates.
+The check function examines every record associated with the type for obvious
+errors and cross-references healthy records against other metadata to look for
+inconsistencies.
+Repairs for this class of scrub item are simple, since the repair function
+starts by holding all the resources acquired in the previous step.
+The repair function scans available metadata as needed to record all the
+observations needed to complete the structure.
+Next, it stages the observations in a new ondisk structure and commits it
+atomically to complete the repair.
+Finally, the storage from the old data structure are carefully reaped.
+
+Because ``xfs_scrub`` locks a primary object for the duration of the repair,
+this is effectively an offline repair operation performed on a subset of the
+filesystem.
+This minimizes the complexity of the repair code because it is not necessary to
+handle concurrent updates from other threads, nor is it necessary to access
+any other part of the filesystem.
+As a result, indexed structures can be rebuilt very quickly, and programs
+trying to access the damaged structure will be blocked until repairs complete.
+The only infrastructure needed by the repair code are the staging area for
+observations and a means to write new structures to disk.
+Despite these limitations, the advantage that online repair holds is clear:
+targeted work on individual shards of the filesystem avoids total loss of
+service.
+
+This mechanism is described in section 2.1 ("Off-Line Algorithm") of
+V. Srinivasan and M. J. Carey, `"Performance of On-Line Index Construction
+Algorithms" <https://minds.wisconsin.edu/bitstream/handle/1793/59524/TR1047.pdf>`_,
+*Extending Database Technology*, pp. 293-309, 1992.
+
+Most primary metadata repair functions stage their intermediate results in an
+in-memory array prior to formatting the new ondisk structure, which is very
+similar to the list-based algorithm discussed in section 2.3 ("List-Based
+Algorithms") of Srinivasan.
+However, any data structure builder that maintains a resource lock for the
+duration of the repair is *always* an offline algorithm.
+
+.. _secondary_metadata:
+
+Secondary Metadata
+``````````````````
+
+Metadata structures in this category reflect records found in primary metadata,
+but are only needed for online fsck or for reorganization of the filesystem.
+
+Secondary metadata include:
+
+- Reverse mapping information
+
+- Directory parent pointers
+
+This class of metadata is difficult for scrub to process because scrub attaches
+to the secondary object but needs to check primary metadata, which runs counter
+to the usual order of resource acquisition.
+Frequently, this means that full filesystems scans are necessary to rebuild the
+metadata.
+Check functions can be limited in scope to reduce runtime.
+Repairs, however, require a full scan of primary metadata, which can take a
+long time to complete.
+Under these conditions, ``xfs_scrub`` cannot lock resources for the entire
+duration of the repair.
+
+Instead, repair functions set up an in-memory staging structure to store
+observations.
+Depending on the requirements of the specific repair function, the staging
+index will either have the same format as the ondisk structure or a design
+specific to that repair function.
+The next step is to release all locks and start the filesystem scan.
+When the repair scanner needs to record an observation, the staging data are
+locked long enough to apply the update.
+While the filesystem scan is in progress, the repair function hooks the
+filesystem so that it can apply pending filesystem updates to the staging
+information.
+Once the scan is done, the owning object is re-locked, the live data is used to
+write a new ondisk structure, and the repairs are committed atomically.
+The hooks are disabled and the staging staging area is freed.
+Finally, the storage from the old data structure are carefully reaped.
+
+Introducing concurrency helps online repair avoid various locking problems, but
+comes at a high cost to code complexity.
+Live filesystem code has to be hooked so that the repair function can observe
+updates in progress.
+The staging area has to become a fully functional parallel structure so that
+updates can be merged from the hooks.
+Finally, the hook, the filesystem scan, and the inode locking model must be
+sufficiently well integrated that a hook event can decide if a given update
+should be applied to the staging structure.
+
+In theory, the scrub implementation could apply these same techniques for
+primary metadata, but doing so would make it massively more complex and less
+performant.
+Programs attempting to access the damaged structures are not blocked from
+operation, which may cause application failure or an unplanned filesystem
+shutdown.
+
+Inspiration for the secondary metadata repair strategy was drawn from section
+2.4 of Srinivasan above, and sections 2 ("NSF: Inded Build Without Side-File")
+and 3.1.1 ("Duplicate Key Insert Problem") in C. Mohan, `"Algorithms for
+Creating Indexes for Very Large Tables Without Quiescing Updates"
+<https://dl.acm.org/doi/10.1145/130283.130337>`_, 1992.
+
+The sidecar index mentioned above bears some resemblance to the side file
+method mentioned in Srinivasan and Mohan.
+Their method consists of an index builder that extracts relevant record data to
+build the new structure as quickly as possible; and an auxiliary structure that
+captures all updates that would be committed to the index by other threads were
+the new index already online.
+After the index building scan finishes, the updates recorded in the side file
+are applied to the new index.
+To avoid conflicts between the index builder and other writer threads, the
+builder maintains a publicly visible cursor that tracks the progress of the
+scan through the record space.
+To avoid duplication of work between the side file and the index builder, side
+file updates are elided when the record ID for the update is greater than the
+cursor position within the record ID space.
+
+To minimize changes to the rest of the codebase, XFS online repair keeps the
+replacement index hidden until it's completely ready to go.
+In other words, there is no attempt to expose the keyspace of the new index
+while repair is running.
+The complexity of such an approach would be very high and perhaps more
+appropriate to building *new* indices.
+
+**Future Work Question**: Can the full scan and live update code used to
+facilitate a repair also be used to implement a comprehensive check?
+
+*Answer*: In theory, yes.  Check would be much stronger if each scrub function
+employed these live scans to build a shadow copy of the metadata and then
+compared the shadow records to the ondisk records.
+However, doing that is a fair amount more work than what the checking functions
+do now.
+The live scans and hooks were developed much later.
+That in turn increases the runtime of those scrub functions.
+
+Summary Information
+```````````````````
+
+Metadata structures in this last category summarize the contents of primary
+metadata records.
+These are often used to speed up resource usage queries, and are many times
+smaller than the primary metadata which they represent.
+
+Examples of summary information include:
+
+- Summary counts of free space and inodes
+
+- File link counts from directories
+
+- Quota resource usage counts
+
+Check and repair require full filesystem scans, but resource and lock
+acquisition follow the same paths as regular filesystem accesses.
+
+The superblock summary counters have special requirements due to the underlying
+implementation of the incore counters, and will be treated separately.
+Check and repair of the other types of summary counters (quota resource counts
+and file link counts) employ the same filesystem scanning and hooking
+techniques as outlined above, but because the underlying data are sets of
+integer counters, the staging data need not be a fully functional mirror of the
+ondisk structure.
+
+Inspiration for quota and file link count repair strategies were drawn from
+sections 2.12 ("Online Index Operations") through 2.14 ("Incremental View
+Maintenace") of G.  Graefe, `"Concurrent Queries and Updates in Summary Views
+and Their Indexes"
+<http://www.odbms.org/wp-content/uploads/2014/06/Increment-locks.pdf>`_, 2011.
+
+Since quotas are non-negative integer counts of resource usage, online
+quotacheck can use the incremental view deltas described in section 2.14 to
+track pending changes to the block and inode usage counts in each transaction,
+and commit those changes to a dquot side file when the transaction commits.
+Delta tracking is necessary for dquots because the index builder scans inodes,
+whereas the data structure being rebuilt is an index of dquots.
+Link count checking combines the view deltas and commit step into one because
+it sets attributes of the objects being scanned instead of writing them to a
+separate data structure.
+Each online fsck function will be discussed as case studies later in this
+document.
+
+Risk Management
+---------------
+
+During the development of online fsck, several risk factors were identified
+that may make the feature unsuitable for certain distributors and users.
+Steps can be taken to mitigate or eliminate those risks, though at a cost to
+functionality.
+
+- **Decreased performance**: Adding metadata indices to the filesystem
+  increases the time cost of persisting changes to disk, and the reverse space
+  mapping and directory parent pointers are no exception.
+  System administrators who require the maximum performance can disable the
+  reverse mapping features at format time, though this choice dramatically
+  reduces the ability of online fsck to find inconsistencies and repair them.
+
+- **Incorrect repairs**: As with all software, there might be defects in the
+  software that result in incorrect repairs being written to the filesystem.
+  Systematic fuzz testing (detailed in the next section) is employed by the
+  authors to find bugs early, but it might not catch everything.
+  The kernel build system provides Kconfig options (``CONFIG_XFS_ONLINE_SCRUB``
+  and ``CONFIG_XFS_ONLINE_REPAIR``) to enable distributors to choose not to
+  accept this risk.
+  The xfsprogs build system has a configure option (``--enable-scrub=no``) that
+  disables building of the ``xfs_scrub`` binary, though this is not a risk
+  mitigation if the kernel functionality remains enabled.
+
+- **Inability to repair**: Sometimes, a filesystem is too badly damaged to be
+  repairable.
+  If the keyspaces of several metadata indices overlap in some manner but a
+  coherent narrative cannot be formed from records collected, then the repair
+  fails.
+  To reduce the chance that a repair will fail with a dirty transaction and
+  render the filesystem unusable, the online repair functions have been
+  designed to stage and validate all new records before committing the new
+  structure.
+
+- **Misbehavior**: Online fsck requires many privileges -- raw IO to block
+  devices, opening files by handle, ignoring Unix discretionary access control,
+  and the ability to perform administrative changes.
+  Running this automatically in the background scares people, so the systemd
+  background service is configured to run with only the privileges required.
+  Obviously, this cannot address certain problems like the kernel crashing or
+  deadlocking, but it should be sufficient to prevent the scrub process from
+  escaping and reconfiguring the system.
+  The cron job does not have this protection.
+
+- **Fuzz Kiddiez**: There are many people now who seem to think that running
+  automated fuzz testing of ondisk artifacts to find mischevious behavior and
+  spraying exploit code onto the public mailing list for instant zero-day
+  disclosure is somehow of some social benefit.
+  In the view of this author, the benefit is realized only when the fuzz
+  operators help to **fix** the flaws, but this opinion apparently is not
+  widely shared among security "researchers".
+  The XFS maintainers' continuing ability to manage these events presents an
+  ongoing risk to the stability of the development process.
+  Automated testing should front-load some of the risk while the feature is
+  considered EXPERIMENTAL.
+
+Many of these risks are inherent to software programming.
+Despite this, it is hoped that this new functionality will prove useful in
+reducing unexpected downtime.
+
+3. Testing Plan
+===============
+
+As stated before, fsck tools have three main goals:
+
+1. Detect inconsistencies in the metadata;
+
+2. Eliminate those inconsistencies; and
+
+3. Minimize further loss of data.
+
+Demonstrations of correct operation are necessary to build users' confidence
+that the software behaves within expectations.
+Unfortunately, it was not really feasible to perform regular exhaustive testing
+of every aspect of a fsck tool until the introduction of low-cost virtual
+machines with high-IOPS storage.
+With ample hardware availability in mind, the testing strategy for the online
+fsck project involves differential analysis against the existing fsck tools and
+systematic testing of every attribute of every type of metadata object.
+Testing can be split into four major categories, as discussed below.
+
+Integrated Testing with fstests
+-------------------------------
+
+The primary goal of any free software QA effort is to make testing as
+inexpensive and widespread as possible to maximize the scaling advantages of
+community.
+In other words, testing should maximize the breadth of filesystem configuration
+scenarios and hardware setups.
+This improves code quality by enabling the authors of online fsck to find and
+fix bugs early, and helps developers of new features to find integration
+issues earlier in their development effort.
+
+The Linux filesystem community shares a common QA testing suite,
+`fstests <https://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git/>`_, for
+functional and regression testing.
+Even before development work began on online fsck, fstests (when run on XFS)
+would run both the ``xfs_check`` and ``xfs_repair -n`` commands on the test and
+scratch filesystems between each test.
+This provides a level of assurance that the kernel and the fsck tools stay in
+alignment about what constitutes consistent metadata.
+During development of the online checking code, fstests was modified to run
+``xfs_scrub -n`` between each test to ensure that the new checking code
+produces the same results as the two existing fsck tools.
+
+To start development of online repair, fstests was modified to run
+``xfs_repair`` to rebuild the filesystem's metadata indices between tests.
+This ensures that offline repair does not crash, leave a corrupt filesystem
+after it exists, or trigger complaints from the online check.
+This also established a baseline for what can and cannot be repaired offline.
+To complete the first phase of development of online repair, fstests was
+modified to be able to run ``xfs_scrub`` in a "force rebuild" mode.
+This enables a comparison of the effectiveness of online repair as compared to
+the existing offline repair tools.
+
+General Fuzz Testing of Metadata Blocks
+---------------------------------------
+
+XFS benefits greatly from having a very robust debugging tool, ``xfs_db``.
+
+Before development of online fsck even began, a set of fstests were created
+to test the rather common fault that entire metadata blocks get corrupted.
+This required the creation of fstests library code that can create a filesystem
+containing every possible type of metadata object.
+Next, individual test cases were created to create a test filesystem, identify
+a single block of a specific type of metadata object, trash it with the
+existing ``blocktrash`` command in ``xfs_db``, and test the reaction of a
+particular metadata validation strategy.
+
+This earlier test suite enabled XFS developers to test the ability of the
+in-kernel validation functions and the ability of the offline fsck tool to
+detect and eliminate the inconsistent metadata.
+This part of the test suite was extended to cover online fsck in exactly the
+same manner.
+
+In other words, for a given fstests filesystem configuration:
+
+* For each metadata object existing on the filesystem:
+
+  * Write garbage to it
+
+  * Test the reactions of:
+
+    1. The kernel verifiers to stop obviously bad metadata
+    2. Offline repair (``xfs_repair``) to detect and fix
+    3. Online repair (``xfs_scrub``) to detect and fix
+
+Targeted Fuzz Testing of Metadata Records
+-----------------------------------------
+
+The testing plan for online fsck includes extending the existing fs testing
+infrastructure to provide a much more powerful facility: targeted fuzz testing
+of every metadata field of every metadata object in the filesystem.
+``xfs_db`` can modify every field of every metadata structure in every
+block in the filesystem to simulate the effects of memory corruption and
+software bugs.
+Given that fstests already contains the ability to create a filesystem
+containing every metadata format known to the filesystem, ``xfs_db`` can be
+used to perform exhaustive fuzz testing!
+
+For a given fstests filesystem configuration:
+
+* For each metadata object existing on the filesystem...
+
+  * For each record inside that metadata object...
+
+    * For each field inside that record...
+
+      * For each conceivable type of transformation that can be applied to a bit field...
+
+        1. Clear all bits
+        2. Set all bits
+        3. Toggle the most significant bit
+        4. Toggle the middle bit
+        5. Toggle the least significant bit
+        6. Add a small quantity
+        7. Subtract a small quantity
+        8. Randomize the contents
+
+        * ...test the reactions of:
+
+          1. The kernel verifiers to stop obviously bad metadata
+          2. Offline checking (``xfs_repair -n``)
+          3. Offline repair (``xfs_repair``)
+          4. Online checking (``xfs_scrub -n``)
+          5. Online repair (``xfs_scrub``)
+          6. Both repair tools (``xfs_scrub`` and then ``xfs_repair`` if online repair doesn't succeed)
+
+This is quite the combinatoric explosion!
+
+Fortunately, having this much test coverage makes it easy for XFS developers to
+check the responses of XFS' fsck tools.
+Since the introduction of the fuzz testing framework, these tests have been
+used to discover incorrect repair code and missing functionality for entire
+classes of metadata objects in ``xfs_repair``.
+The enhanced testing was used to finalize the deprecation of ``xfs_check`` by
+confirming that ``xfs_repair`` could detect at least as many corruptions as
+the older tool.
+
+These tests have been very valuable for ``xfs_scrub`` in the same ways -- they
+allow the online fsck developers to compare online fsck against offline fsck,
+and they enable XFS developers to find deficiencies in the code base.
+
+Proposed patchsets include
+`general fuzzer improvements
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfstests-dev.git/log/?h=fuzzer-improvements>`_,
+`fuzzing baselines
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfstests-dev.git/log/?h=fuzz-baseline>`_,
+and `improvements in fuzz testing comprehensiveness
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfstests-dev.git/log/?h=more-fuzz-testing>`_.
+
+Stress Testing
+--------------
+
+A unique requirement to online fsck is the ability to operate on a filesystem
+concurrently with regular workloads.
+Although it is of course impossible to run ``xfs_scrub`` with *zero* observable
+impact on the running system, the online repair code should never introduce
+inconsistencies into the filesystem metadata, and regular workloads should
+never notice resource starvation.
+To verify that these conditions are being met, fstests has been enhanced in
+the following ways:
+
+* For each scrub item type, create a test to exercise checking that item type
+  while running ``fsstress``.
+* For each scrub item type, create a test to exercise repairing that item type
+  while running ``fsstress``.
+* Race ``fsstress`` and ``xfs_scrub -n`` to ensure that checking the whole
+  filesystem doesn't cause problems.
+* Race ``fsstress`` and ``xfs_scrub`` in force-rebuild mode to ensure that
+  force-repairing the whole filesystem doesn't cause problems.
+* Race ``xfs_scrub`` in check and force-repair mode against ``fsstress`` while
+  freezing and thawing the filesystem.
+* Race ``xfs_scrub`` in check and force-repair mode against ``fsstress`` while
+  remounting the filesystem read-only and read-write.
+* The same, but running ``fsx`` instead of ``fsstress``.  (Not done yet?)
+
+Success is defined by the ability to run all of these tests without observing
+any unexpected filesystem shutdowns due to corrupted metadata, kernel hang
+check warnings, or any other sort of mischief.
+
+Proposed patchsets include `general stress testing
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfstests-dev.git/log/?h=race-scrub-and-mount-state-changes>`_
+and the `evolution of existing per-function stress testing
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfstests-dev.git/log/?h=refactor-scrub-stress>`_.
+
+4. User Interface
+=================
+
+The primary user of online fsck is the system administrator, just like offline
+repair.
+Online fsck presents two modes of operation to administrators:
+A foreground CLI process for online fsck on demand, and a background service
+that performs autonomous checking and repair.
+
+Checking on Demand
+------------------
+
+For administrators who want the absolute freshest information about the
+metadata in a filesystem, ``xfs_scrub`` can be run as a foreground process on
+a command line.
+The program checks every piece of metadata in the filesystem while the
+administrator waits for the results to be reported, just like the existing
+``xfs_repair`` tool.
+Both tools share a ``-n`` option to perform a read-only scan, and a ``-v``
+option to increase the verbosity of the information reported.
+
+A new feature of ``xfs_scrub`` is the ``-x`` option, which employs the error
+correction capabilities of the hardware to check data file contents.
+The media scan is not enabled by default because it may dramatically increase
+program runtime and consume a lot of bandwidth on older storage hardware.
+
+The output of a foreground invocation is captured in the system log.
+
+The ``xfs_scrub_all`` program walks the list of mounted filesystems and
+initiates ``xfs_scrub`` for each of them in parallel.
+It serializes scans for any filesystems that resolve to the same top level
+kernel block device to prevent resource overconsumption.
+
+Background Service
+------------------
+
+To reduce the workload of system administrators, the ``xfs_scrub`` package
+provides a suite of `systemd <https://systemd.io/>`_ timers and services that
+run online fsck automatically on weekends by default.
+The background service configures scrub to run with as little privilege as
+possible, the lowest CPU and IO priority, and in a CPU-constrained single
+threaded mode.
+This can be tuned by the systemd administrator at any time to suit the latency
+and throughput requirements of customer workloads.
+
+The output of the background service is also captured in the system log.
+If desired, reports of failures (either due to inconsistencies or mere runtime
+errors) can be emailed automatically by setting the ``EMAIL_ADDR`` environment
+variable in the following service files:
+
+* ``xfs_scrub_fail@.service``
+* ``xfs_scrub_media_fail@.service``
+* ``xfs_scrub_all_fail.service``
+
+The decision to enable the background scan is left to the system administrator.
+This can be done by enabling either of the following services:
+
+* ``xfs_scrub_all.timer`` on systemd systems
+* ``xfs_scrub_all.cron`` on non-systemd systems
+
+This automatic weekly scan is configured out of the box to perform an
+additional media scan of all file data once per month.
+This is less foolproof than, say, storing file data block checksums, but much
+more performant if application software provides its own integrity checking,
+redundancy can be provided elsewhere above the filesystem, or the storage
+device's integrity guarantees are deemed sufficient.
+
+The systemd unit file definitions have been subjected to a security audit
+(as of systemd 249) to ensure that the xfs_scrub processes have as little
+access to the rest of the system as possible.
+This was performed via ``systemd-analyze security``, after which privileges
+were restricted to the minimum required, sandboxing was set up to the maximal
+extent possible with sandboxing and system call filtering; and access to the
+filesystem tree was restricted to the minimum needed to start the program and
+access the filesystem being scanned.
+The service definition files restrict CPU usage to 80% of one CPU core, and
+apply as nice of a priority to IO and CPU scheduling as possible.
+This measure was taken to minimize delays in the rest of the filesystem.
+No such hardening has been performed for the cron job.
+
+Proposed patchset:
+`Enabling the xfs_scrub background service
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=scrub-media-scan-service>`_.
+
+Health Reporting
+----------------
+
+XFS caches a summary of each filesystem's health status in memory.
+The information is updated whenever ``xfs_scrub`` is run, or whenever
+inconsistencies are detected in the filesystem metadata during regular
+operations.
+System administrators should use the ``health`` command of ``xfs_spaceman`` to
+download this information into a human-readable format.
+If problems have been observed, the administrator can schedule a reduced
+service window to run the online repair tool to correct the problem.
+Failing that, the administrator can decide to schedule a maintenance window to
+run the traditional offline repair tool to correct the problem.
+
+**Future Work Question**: Should the health reporting integrate with the new
+inotify fs error notification system?
+Would it be helpful for sysadmins to have a daemon to listen for corruption
+notifications and initiate a repair?
+
+*Answer*: These questions remain unanswered, but should be a part of the
+conversation with early adopters and potential downstream users of XFS.
+
+Proposed patchsets include
+`wiring up health reports to correction returns
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=corruption-health-reports>`_
+and
+`preservation of sickness info during memory reclaim
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=indirect-health-reporting>`_.
+
+5. Kernel Algorithms and Data Structures
+========================================
+
+This section discusses the key algorithms and data structures of the kernel
+code that provide the ability to check and repair metadata while the system
+is running.
+The first chapters in this section reveal the pieces that provide the
+foundation for checking metadata.
+The remainder of this section presents the mechanisms through which XFS
+regenerates itself.
+
+Self Describing Metadata
+------------------------
+
+Starting with XFS version 5 in 2012, XFS updated the format of nearly every
+ondisk block header to record a magic number, a checksum, a universally
+"unique" identifier (UUID), an owner code, the ondisk address of the block,
+and a log sequence number.
+When loading a block buffer from disk, the magic number, UUID, owner, and
+ondisk address confirm that the retrieved block matches the specific owner of
+the current filesystem, and that the information contained in the block is
+supposed to be found at the ondisk address.
+The first three components enable checking tools to disregard alleged metadata
+that doesn't belong to the filesystem, and the fourth component enables the
+filesystem to detect lost writes.
+
+Whenever a file system operation modifies a block, the change is submitted
+to the log as part of a transaction.
+The log then processes these transactions marking them done once they are
+safely persisted to storage.
+The logging code maintains the checksum and the log sequence number of the last
+transactional update.
+Checksums are useful for detecting torn writes and other discrepancies that can
+be introduced between the computer and its storage devices.
+Sequence number tracking enables log recovery to avoid applying out of date
+log updates to the filesystem.
+
+These two features improve overall runtime resiliency by providing a means for
+the filesystem to detect obvious corruption when reading metadata blocks from
+disk, but these buffer verifiers cannot provide any consistency checking
+between metadata structures.
+
+For more information, please see the documentation for
+Documentation/filesystems/xfs-self-describing-metadata.rst
+
+Reverse Mapping
+---------------
+
+The original design of XFS (circa 1993) is an improvement upon 1980s Unix
+filesystem design.
+In those days, storage density was expensive, CPU time was scarce, and
+excessive seek time could kill performance.
+For performance reasons, filesystem authors were reluctant to add redundancy to
+the filesystem, even at the cost of data integrity.
+Filesystems designers in the early 21st century choose different strategies to
+increase internal redundancy -- either storing nearly identical copies of
+metadata, or more space-efficient encoding techniques.
+
+For XFS, a different redundancy strategy was chosen to modernize the design:
+a secondary space usage index that maps allocated disk extents back to their
+owners.
+By adding a new index, the filesystem retains most of its ability to scale
+well to heavily threaded workloads involving large datasets, since the primary
+file metadata (the directory tree, the file block map, and the allocation
+groups) remain unchanged.
+Like any system that improves redundancy, the reverse-mapping feature increases
+overhead costs for space mapping activities.
+However, it has two critical advantages: first, the reverse index is key to
+enabling online fsck and other requested functionality such as free space
+defragmentation, better media failure reporting, and filesystem shrinking.
+Second, the different ondisk storage format of the reverse mapping btree
+defeats device-level deduplication because the filesystem requires real
+redundancy.
+

+| **Sidebar**:                                                             |
++--------------------------------------------------------------------------+
+| A criticism of adding the secondary index is that it does nothing to     |
+| improve the robustness of user data storage itself.                      |
+| This is a valid point, but adding a new index for file data block        |
+| checksums increases write amplification by turning data overwrites into  |
+| copy-writes, which age the filesystem prematurely.                       |
+| In keeping with thirty years of precedent, users who want file data      |
+| integrity can supply as powerful a solution as they require.             |

++--------------------------------------------------------------------------+
+
+The information captured in a reverse space mapping record is as follows:
+
+.. code-block:: c
+
+	struct xfs_rmap_irec {
+	    xfs_agblock_t    rm_startblock;   /* extent start block */
+	    xfs_extlen_t     rm_blockcount;   /* extent length */
+	    uint64_t         rm_owner;        /* extent owner */
+	    uint64_t         rm_offset;       /* offset within the owner */
+	    unsigned int     rm_flags;        /* state flags */
+	};
+
+The first two fields capture the location and size of the physical space,
+in units of filesystem blocks.
+The owner field tells scrub which metadata structure or file inode have been
+assigned this space.
+For space allocated to files, the offset field tells scrub where the space was
+mapped within the file fork.
+Finally, the flags field provides extra information about the space usage --
+is this an attribute fork extent?  A file mapping btree extent?  Or an
+unwritten data extent?
+
+Online filesystem checking judges the consistency of each primary metadata
+record by comparing its information against all other space indices.
+The reverse mapping index plays a key role in the consistency checking process
+because it contains a centralized alternate copy of all space allocation
+information.
+Program runtime and ease of resource acquisition are the only real limits to
+what online checking can consult.
+For example, a file data extent mapping can be checked against:
+
+* The absence of an entry in the free space information.
+* The absence of an entry in the inode index.
+* The absence of an entry in the reference count data if the file is not
+  marked as having shared extents.
+* The correspondence of an entry in the reverse mapping information.
+
+There are several observations to make about reverse mapping indices:
+
+1. Reverse mappings can provide a positive affirmation of correctness if any of
+   the above primary metadata are in doubt.
+   The checking code for most primary metadata follows a path similar to the
+   one outlined above.
+
+2. Proving the consistency of secondary metadata with the primary metadata is
+   difficult because that requires a full scan of all primary space metadata,
+   which is very time intensive.
+   For example, checking a reverse mapping record for a file extent mapping
+   btree block requires locking the file and searching the entire btree to
+   confirm the block.
+   Instead, scrub relies on rigorous cross-referencing during the primary space
+   mapping structure checks.
+
+3. Consistency scans must use non-blocking lock acquisition primitives if the
+   required locking order is not the same order used by regular filesystem
+   operations.
+   For example, if the filesystem normally takes a file ILOCK before taking
+   the AGF buffer lock but scrub wants to take a file ILOCK while holding
+   an AGF buffer lock, scrub cannot block on that second acquisition.
+   This means that forward progress during this part of a scan of the reverse
+   mapping data cannot be guaranteed if system load is heavy.
+
+In summary, reverse mappings play a key role in reconstruction of primary
+metadata.
+The details of how these records are staged, written to disk, and committed
+into the filesystem are covered in subsequent sections.
+
+Checking and Cross-Referencing
+------------------------------
+
+The first step of checking a metadata structure is to examine every record
+contained within the structure and its relationship with the rest of the
+system.
+XFS contains multiple layers of checking to try to prevent inconsistent
+metadata from wreaking havoc on the system.
+Each of these layers contributes information that helps the kernel to make
+three decisions about the health of a metadata structure:
+
+- Is a part of this structure obviously corrupt (``XFS_SCRUB_OFLAG_CORRUPT``) ?
+- Is this structure inconsistent with the rest of the system
+  (``XFS_SCRUB_OFLAG_XCORRUPT``) ?
+- Is there so much damage around the filesystem that cross-referencing is not
+  possible (``XFS_SCRUB_OFLAG_XFAIL``) ?
+- Can the structure be optimized to improve performance or reduce the size of
+  metadata (``XFS_SCRUB_OFLAG_PREEN``) ?
+- Does the structure contain data that is not inconsistent but deserves review
+  by the system administrator (``XFS_SCRUB_OFLAG_WARNING``) ?
+
+The following sections describe how the metadata scrubbing process works.
+
+Metadata Buffer Verification
+````````````````````````````
+
+The lowest layer of metadata protection in XFS are the metadata verifiers built
+into the buffer cache.
+These functions perform inexpensive internal consistency checking of the block
+itself, and answer these questions:
+
+- Does the block belong to this filesystem?
+
+- Does the block belong to the structure that asked for the read?
+  This assumes that metadata blocks only have one owner, which is always true
+  in XFS.
+
+- Is the type of data stored in the block within a reasonable range of what
+  scrub is expecting?
+
+- Does the physical location of the block match the location it was read from?
+
+- Does the block checksum match the data?
+
+The scope of the protections here are very limited -- verifiers can only
+establish that the filesystem code is reasonably free of gross corruption bugs
+and that the storage system is reasonably competent at retrieval.
+Corruption problems observed at runtime cause the generation of health reports,
+failed system calls, and in the extreme case, filesystem shutdowns if the
+corrupt metadata force the cancellation of a dirty transaction.
+
+Every online fsck scrubbing function is expected to read every ondisk metadata
+block of a structure in the course of checking the structure.
+Corruption problems observed during a check are immediately reported to
+userspace as corruption; during a cross-reference, they are reported as a
+failure to cross-reference once the full examination is complete.
+Reads satisfied by a buffer already in cache (and hence already verified)
+bypass these checks.
+
+Internal Consistency Checks
+```````````````````````````
+
+After the buffer cache, the next level of metadata protection is the internal
+record verification code built into the filesystem.
+These checks are split between the buffer verifiers, the in-filesystem users of
+the buffer cache, and the scrub code itself, depending on the amount of higher
+level context required.
+The scope of checking is still internal to the block.
+These higher level checking functions answer these questions:
+
+- Does the type of data stored in the block match what scrub is expecting?
+
+- Does the block belong to the owning structure that asked for the read?
+
+- If the block contains records, do the records fit within the block?
+
+- If the block tracks internal free space information, is it consistent with
+  the record areas?
+
+- Are the records contained inside the block free of obvious corruptions?
+
+Record checks in this category are more rigorous and more time-intensive.
+For example, block pointers and inumbers are checked to ensure that they point
+within the dynamically allocated parts of an allocation group and within
+the filesystem.
+Names are checked for invalid characters, and flags are checked for invalid
+combinations.
+Other record attributes are checked for sensible values.
+Btree records spanning an interval of the btree keyspace are checked for
+correct order and lack of mergeability (except for file fork mappings).
+For performance reasons, regular code may skip some of these checks unless
+debugging is enabled or a write is about to occur.
+Scrub functions, of course, must check all possible problems.
+
+Validation of Userspace-Controlled Record Attributes
+````````````````````````````````````````````````````
+
+Various pieces of filesystem metadata are directly controlled by userspace.
+Because of this nature, validation work cannot be more precise than checking
+that a value is within the possible range.
+These fields include:
+
+- Superblock fields controlled by mount options
+- Filesystem labels
+- File timestamps
+- File permissions
+- File size
+- File flags
+- Names present in directory entries, extended attribute keys, and filesystem
+  labels
+- Extended attribute key namespaces
+- Extended attribute values
+- File data block contents
+- Quota limits
+- Quota timer expiration (if resource usage exceeds the soft limit)
+
+Cross-Referencing Space Metadata
+````````````````````````````````
+
+After internal block checks, the next higher level of checking is
+cross-referencing records between metadata structures.
+For regular runtime code, the cost of these checks is considered to be
+prohibitively expensive, but as scrub is dedicated to rooting out
+inconsistencies, it must pursue all avenues of inquiry.
+The exact set of cross-referencing is highly dependent on the context of the
+data structure being checked.
+
+The XFS btree code has keyspace scanning functions that online fsck uses to
+cross reference one structure with another.
+Specifically, scrub can scan the key space of an index to determine if that
+keyspace is fully, sparsely, or not at all mapped to records.
+For the reverse mapping btree, it is possible to mask parts of the key for the
+purposes of performing a keyspace scan so that scrub can decide if the rmap
+btree contains records mapping a certain extent of physical space without the
+sparsenses of the rest of the rmap keyspace getting in the way.
+
+Btree blocks undergo the following checks before cross-referencing:
+
+- Does the type of data stored in the block match what scrub is expecting?
+
+- Does the block belong to the owning structure that asked for the read?
+
+- Do the records fit within the block?
+
+- Are the records contained inside the block free of obvious corruptions?
+
+- Are the name hashes in the correct order?
+
+- Do node pointers within the btree point to valid block addresses for the type
+  of btree?
+
+- Do child pointers point towards the leaves?
+
+- Do sibling pointers point across the same level?
+
+- For each node block record, does the record key accurate reflect the contents
+  of the child block?
+
+Space allocation records are cross-referenced as follows:
+
+1. Any space mentioned by any metadata structure are cross-referenced as
+   follows:
+
+   - Does the reverse mapping index list only the appropriate owner as the
+     owner of each block?
+
+   - Are none of the blocks claimed as free space?
+
+   - If these aren't file data blocks, are none of the blocks claimed as space
+     shared by different owners?
+
+2. Btree blocks are cross-referenced as follows:
+
+   - Everything in class 1 above.
+
+   - If there's a parent node block, do the keys listed for this block match the
+     keyspace of this block?
+
+   - Do the sibling pointers point to valid blocks?  Of the same level?
+
+   - Do the child pointers point to valid blocks?  Of the next level down?
+
+3. Free space btree records are cross-referenced as follows:
+
+   - Everything in class 1 and 2 above.
+
+   - Does the reverse mapping index list no owners of this space?
+
+   - Is this space not claimed by the inode index for inodes?
+
+   - Is it not mentioned by the reference count index?
+
+   - Is there a matching record in the other free space btree?
+
+4. Inode btree records are cross-referenced as follows:
+
+   - Everything in class 1 and 2 above.
+
+   - Is there a matching record in free inode btree?
+
+   - Do cleared bits in the holemask correspond with inode clusters?
+
+   - Do set bits in the freemask correspond with inode records with zero link
+     count?
+
+5. Inode records are cross-referenced as follows:
+
+   - Everything in class 1.
+
+   - Do all the fields that summarize information about the file forks actually
+     match those forks?
+
+   - Does each inode with zero link count correspond to a record in the free
+     inode btree?
+
+6. File fork space mapping records are cross-referenced as follows:
+
+   - Everything in class 1 and 2 above.
+
+   - Is this space not mentioned by the inode btrees?
+
+   - If this is a CoW fork mapping, does it correspond to a CoW entry in the
+     reference count btree?
+
+7. Reference count records are cross-referenced as follows:
+
+   - Everything in class 1 and 2 above.
+
+   - Within the space subkeyspace of the rmap btree (that is to say, all
+     records mapped to a particular space extent and ignoring the owner info),
+     are there the same number of reverse mapping records for each block as the
+     reference count record claims?
+
+Proposed patchsets are the series to find gaps in
+`refcount btree
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=scrub-detect-refcount-gaps>`_,

+before starting a repair.
+
+Checking Extended Attributes
+````````````````````````````
+
+Extended attributes implement a key-value store that enable fragments of data
+to be attached to any file.
+Both the kernel and userspace can access the keys and values, subject to
+namespace and privilege restrictions.
+Most typically these fragments are metadata about the file -- origins, security
+contexts, user-supplied labels, indexing information, etc.
+
+Names can be as long as 255 bytes and can exist in several different
+namespaces.
+Values can be as large as 64KB.
+A file's extended attributes are stored in blocks mapped by the attr fork.
+The mappings point to leaf blocks, remote value blocks, or dabtree blocks.
+Block 0 in the attribute fork is always the top of the structure, but otherwise
+each of the three types of blocks can be found at any offset in the attr fork.
+Leaf blocks contain attribute key records that point to the name and the value.
+Names are always stored elsewhere in the same leaf block.
+Values that are less than 3/4 the size of a filesystem block are also stored
+elsewhere in the same leaf block.
+Remote value blocks contain values that are too large to fit inside a leaf.
+If the leaf information exceeds a single filesystem block, a dabtree (also
+rooted at block 0) is created to map hashes of the attribute names to leaf
+blocks in the attr fork.
+
+Checking an extended attribute structure is not so straightfoward due to the
+lack of separation between attr blocks and index blocks.
+Scrub must read each block mapped by the attr fork and ignore the non-leaf
+blocks:
+
+1. Walk the dabtree in the attr fork (if present) to ensure that there are no
+   irregularities in the blocks or dabtree mappings that do not point to
+   attr leaf blocks.
+
+2. Walk the blocks of the attr fork looking for leaf blocks.
+   For each entry inside a leaf:
+
+   a. Validate that the name does not contain invalid characters.
+
+   b. Read the attr value.
+      This performs a named lookup of the attr name to ensure the correctness
+      of the dabtree.
+      If the value is stored in a remote block, this also validates the
+      integrity of the remote value block.
+
+Checking and Cross-Referencing Directories
+``````````````````````````````````````````
+
+The filesystem directory tree is a directed acylic graph structure, with files
+constituting the nodes, and directory entries (dirents) constituting the edges.
+Directories are a special type of file containing a set of mappings from a
+255-byte sequence (name) to an inumber.
+These are called directory entries, or dirents for short.
+Each directory file must have exactly one directory pointing to the file.
+A root directory points to itself.
+Directory entries point to files of any type.
+Each non-directory file may have multiple directories point to it.
+
+In XFS, directories are implemented as a file containing up to three 32GB
+partitions.
+The first partition contains directory entry data blocks.
+Each data block contains variable-sized records associating a user-provided
+name with an inumber and, optionally, a file type.
+If the directory entry data grows beyond one block, the second partition (which
+exists as post-EOF extents) is populated with a block containing free space
+information and an index that maps hashes of the dirent names to directory data
+blocks in the first partition.
+This makes directory name lookups very fast.
+If this second partition grows beyond one block, the third partition is
+populated with a linear array of free space information for faster
+expansions.
+If the free space has been separated and the second partition grows again
+beyond one block, then a dabtree is used to map hashes of dirent names to
+directory data blocks.
+
+Checking a directory is pretty straightfoward:
+
+1. Walk the dabtree in the second partition (if present) to ensure that there
+   are no irregularities in the blocks or dabtree mappings that do not point to
+   dirent blocks.
+
+2. Walk the blocks of the first partition looking for directory entries.
+   Each dirent is checked as follows:
+
+   a. Does the name contain no invalid characters?
+
+   b. Does the inumber correspond to an actual, allocated inode?
+
+   c. Does the child inode have a nonzero link count?
+
+   d. If a file type is included in the dirent, does it match the type of the
+      inode?
+
+   e. If the child is a subdirectory, does the child's dotdot pointer point
+      back to the parent?
+
+   f. If the directory has a second partition, perform a named lookup of the
+      dirent name to ensure the correctness of the dabtree.
+
+3. Walk the free space list in the third partition (if present) to ensure that
+   the free spaces it describes are really unused.
+
+Checking operations involving :ref:`parents <dirparent>` and
+:ref:`file link counts <nlinks>` are discussed in more detail in later
+sections.
+
+Checking Directory/Attribute Btrees
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+As stated in previous sections, the directory/attribute btree (dabtree) index
+maps user-provided names to improve lookup times by avoiding linear scans.
+Internally, it maps a 32-bit hash of the name to a block offset within the
+appropriate file fork.
+
+The internal structure of a dabtree closely resembles the btrees that record
+fixed-size metadata records -- each dabtree block contains a magic number, a
+checksum, sibling pointers, a UUID, a tree level, and a log sequence number.
+The format of leaf and node records are the same -- each entry points to the
+next level down in the hierarchy, with dabtree node records pointing to dabtree
+leaf blocks, and dabtree leaf records pointing to non-dabtree blocks elsewhere
+in the fork.
+
+Checking and cross-referencing the dabtree is very similar to what is done for
+space btrees:
+
+- Does the type of data stored in the block match what scrub is expecting?
+
+- Does the block belong to the owning structure that asked for the read?
+
+- Do the records fit within the block?
+
+- Are the records contained inside the block free of obvious corruptions?
+
+- Are the name hashes in the correct order?
+
+- Do node pointers within the dabtree point to valid fork offsets for dabtree
+  blocks?
+
+- Do leaf pointers within the dabtree point to valid fork offsets for directory
+  or attr leaf blocks?
+
+- Do child pointers point towards the leaves?
+
+- Do sibling pointers point across the same level?
+
+- For each dabtree node record, does the record key accurate reflect the
+  contents of the child dabtree block?
+
+- For each dabtree leaf record, does the record key accurate reflect the
+  contents of the directory or attr block?
+
+Cross-Referencing Summary Counters
+``````````````````````````````````
+
+XFS maintains three classes of summary counters: available resources, quota
+resource usage, and file link counts.
+
+In theory, the amount of available resources (data blocks, inodes, realtime
+extents) can be found by walking the entire filesystem.
+This would make for very slow reporting, so a transactional filesystem can
+maintain summaries of this information in the superblock.
+Cross-referencing these values against the filesystem metadata should be a
+simple matter of walking the free space and inode metadata in each AG and the
+realtime bitmap, but there are complications that will be discussed in
+:ref:`more detail <fscounters>` later.
+
+:ref:`Quota usage <quotacheck>` and :ref:`file link count <nlinks>`
+checking are sufficiently complicated to warrant separate sections.
+
+Post-Repair Reverification
+``````````````````````````
+
+After performing a repair, the checking code is run a second time to validate
+the new structure, and the results of the health assessment are recorded
+internally and returned to the calling process.
+This step is critical for enabling system administrator to monitor the status
+of the filesystem and the progress of any repairs.
+For developers, it is a useful means to judge the efficacy of error detection
+and correction in the online and offline checking tools.
+
+Eventual Consistency vs. Online Fsck
+------------------------------------
+
+Complex operations can make modifications to multiple per-AG data structures
+with a chain of transactions.
+These chains, once committed to the log, are restarted during log recovery if
+the system crashes while processing the chain.
+Because the AG header buffers are unlocked between transactions within a chain,
+online checking must coordinate with chained operations that are in progress to
+avoid incorrectly detecting inconsistencies due to pending chains.
+Furthermore, online repair must not run when operations are pending because
+the metadata are temporarily inconsistent with each other, and rebuilding is
+not possible.
+
+Only online fsck has this requirement of total consistency of AG metadata, and
+should be relatively rare as compared to filesystem change operations.
+Online fsck coordinates with transaction chains as follows:
+
+* For each AG, maintain a count of intent items targetting that AG.
+  The count should be bumped whenever a new item is added to the chain.
+  The count should be dropped when the filesystem has locked the AG header
+  buffers and finished the work.
+
+* When online fsck wants to examine an AG, it should lock the AG header
+  buffers to quiesce all transaction chains that want to modify that AG.
+  If the count is zero, proceed with the checking operation.
+  If it is nonzero, cycle the buffer locks to allow the chain to make forward
+  progress.
+
+This may lead to online fsck taking a long time to complete, but regular
+filesystem updates take precedence over background checking activity.
+Details about the discovery of this situation are presented in the
+:ref:`next section <chain_coordination>`, and details about the solution
+are presented :ref:`after that<intent_drains>`.
+
+.. _chain_coordination:
+
+Discovery of the Problem
+````````````````````````
+
+Midway through the development of online scrubbing, the fsstress tests
+uncovered a misinteraction between online fsck and compound transaction chains
+created by other writer threads that resulted in false reports of metadata
+inconsistency.
+The root cause of these reports is the eventual consistency model introduced by
+the expansion of deferred work items and compound transaction chains when
+reverse mapping and reflink were introduced.
+
+Originally, transaction chains were added to XFS to avoid deadlocks when
+unmapping space from files.
+Deadlock avoidance rules require that AGs only be locked in increasing order,
+which makes it impossible (say) to use a single transaction to free a space
+extent in AG 7 and then try to free a now superfluous block mapping btree block
+in AG 3.
+To avoid these kinds of deadlocks, XFS creates Extent Freeing Intent (EFI) log
+items to commit to freeing some space in one transaction while deferring the
+actual metadata updates to a fresh transaction.
+The transaction sequence looks like this:
+
+1. The first transaction contains a physical update to the file's block mapping
+   structures to remove the mapping from the btree blocks.
+   It then attaches to the in-memory transaction an action item to schedule
+   deferred freeing of space.
+   Concretely, each transaction maintains a list of ``struct
+   xfs_defer_pending`` objects, each of which maintains a list of ``struct
+   xfs_extent_free_item`` objects.
+   Returning to the example above, the action item tracks the freeing of both
+   the unmapped space from AG 7 and the block mapping btree (BMBT) block from
+   AG 3.
+   Deferred frees recorded in this manner are committed in the log by creating
+   an EFI log item from the ``struct xfs_extent_free_item`` object and
+   attaching the log item to the transaction.
+   When the log is persisted to disk, the EFI item is written into the ondisk
+   transaction record.
+   EFIs can list up to 16 extents to free, all sorted in AG order.
+
+2. The second transaction contains a physical update to the free space btrees
+   of AG 3 to release the former BMBT block and a second physical update to the
+   free space btrees of AG 7 to release the unmapped file space.
+   Observe that the the physical updates are resequenced in the correct order
+   when possible.
+   Attached to the transaction is a an extent free done (EFD) log item.
+   The EFD contains a pointer to the EFI logged in transaction #1 so that log
+   recovery can tell if the EFI needs to be replayed.
+
+If the system goes down after transaction #1 is written back to the filesystem
+but before #2 is committed, a scan of the filesystem metadata would show
+inconsistent filesystem metadata because there would not appear to be any owner
+of the unmapped space.
+Happily, log recovery corrects this inconsistency for us -- when recovery finds
+an intent log item but does not find a corresponding intent done item, it will
+reconstruct the incore state of the intent item and finish it.
+In the example above, the log must replay both frees described in the recovered
+EFI to complete the recovery phase.
+
+There are subtleties to XFS' transaction chaining strategy to consider:
+
+* Log items must be added to a transaction in the correct order to prevent
+  conflicts with principal objects that are not held by the transaction.
+  In other words, all per-AG metadata updates for an unmapped block must be
+  completed before the last update to free the extent, and extents should not
+  be reallocated until that last update commits to the log.
+
+* AG header buffers are released between each transaction in a chain.
+  This means that other threads can observe an AG in an intermediate state,
+  but as long as the first subtlety is handled, this should not affect the
+  correctness of filesystem operations.
+
+* Unmounting the filesystem flushes all pending work to disk, which means that
+  offline fsck never sees the temporary inconsistencies caused by deferred
+  work item processing.
+
+In this manner, XFS employs a form of eventual consistency to avoid deadlocks
+and increase parallelism.
+
+During the design phase of the reverse mapping and reflink features, it was
+decided that it was impractical to cram all the reverse mapping updates for a
+single filesystem change into a single transaction because a single file
+mapping operation can explode into many small updates:
+
+* The block mapping update itself
+* A reverse mapping update for the block mapping update
+* Fixing the freelist
+* A reverse mapping update for the freelist fix
+
+* A shape change to the block mapping btree
+* A reverse mapping update for the btree update
+* Fixing the freelist (again)
+* A reverse mapping update for the freelist fix
+
+* An update to the reference counting information
+* A reverse mapping update for the refcount update
+* Fixing the freelist (a third time)
+* A reverse mapping update for the freelist fix
+
+* Freeing any space that was unmapped and not owned by any other file
+* Fixing the freelist (a fourth time)
+* A reverse mapping update for the freelist fix
+
+* Freeing the space used by the block mapping btree
+* Fixing the freelist (a fifth time)
+* A reverse mapping update for the freelist fix
+
+Free list fixups are not usually needed more than once per AG per transaction
+chain, but it is theoretically possible if space is very tight.
+For copy-on-write updates this is even worse, because this must be done once to
+remove the space from a staging area and again to map it into the file!
+
+To deal with this explosion in a calm manner, XFS expands its use of deferred
+work items to cover most reverse mapping updates and all refcount updates.
+This reduces the worst case size of transaction reservations by breaking the
+work into a long chain of small updates, which increases the degree of eventual
+consistency in the system.
+Again, this generally isn't a problem because XFS orders its deferred work
+items carefully to avoid resource reuse conflicts between unsuspecting threads.
+
+However, online fsck changes the rules -- remember that although physical
+updates to per-AG structures are coordinated by locking the buffers for AG
+headers, buffer locks are dropped between transactions.
+Once scrub acquires resources and takes locks for a data structure, it must do
+all the validation work without releasing the lock.
+If the main lock for a space btree is an AG header buffer lock, scrub may have
+interrupted another thread that is midway through finishing a chain.
+For example, if a thread performing a copy-on-write has completed a reverse
+mapping update but not the corresponding refcount update, the two AG btrees
+will appear inconsistent to scrub and an observation of corruption will be
+recorded.  This observation will not be correct.
+If a repair is attempted in this state, the results will be catastrophic!
+
+Several other solutions to this problem were evaluated upon discovery of this
+flaw and rejected:
+
+1. Add a higher level lock to allocation groups and require writer threads to
+   acquire the higher level lock in AG order before making any changes.
+   This would be very difficult to implement in practice because it is
+   difficult to determine which locks need to be obtained, and in what order,
+   without simulating the entire operation.
+   Performing a dry run of a file operation to discover necessary locks would
+   make the filesystem very slow.
+
+2. Make the deferred work coordinator code aware of consecutive intent items
+   targeting the same AG and have it hold the AG header buffers locked across
+   the transaction roll between updates.
+   This would introduce a lot of complexity into the coordinator since it is
+   only loosely coupled with the actual deferred work items.
+   It would also fail to solve the problem because deferred work items can
+   generate new deferred subtasks, but all subtasks must be complete before
+   work can start on a new sibling task.
+
+3. Teach online fsck to walk all transactions waiting for whichever lock(s)
+   protect the data structure being scrubbed to look for pending operations.
+   The checking and repair operations must factor these pending operations into
+   the evaluations being performed.
+   This solution is a nonstarter because it is *extremely* invasive to the main
+   filesystem.
+
+.. _intent_drains:
+
+Intent Drains
+`````````````
+
+Online fsck uses an atomic intent item counter and lock cycling to coordinate
+with transaction chains.
+There are two key properties to the drain mechanism.
+First, the counter is incremented when a deferred work item is *queued* to a
+transaction, and it is decremented after the associated intent done log item is
+*committed* to another transaction.
+The second property is that deferred work can be added to a transaction without
+holding an AG header lock, but per-AG work items cannot be marked done without
+locking that AG header buffer to log the physical updates and the intent done
+log item.
+The first property enables scrub to yield to running transaction chains, which
+is an explicit deprioritization of online fsck to benefit file operations.
+The second property of the drain is key to the correct coordination of scrub,
+since scrub will always be able to decide if a conflict is possible.
+
+For regular filesystem code, the drain works as follows:
+
+1. Call the appropriate subsystem function to add a deferred work item to a
+   transaction.
+
+2. The function calls ``xfs_defer_drain_bump`` to increase the counter.
+
+3. When the deferred item manager wants to finish the deferred work item, it
+   calls ``->finish_item`` to complete it.
+
+4. The ``->finish_item`` implementation logs some changes and calls
+   ``xfs_defer_drain_drop`` to decrease the sloppy counter and wake up any threads
+   waiting on the drain.
+
+5. The subtransaction commits, which unlocks the resource associated with the
+   intent item.
+
+For scrub, the drain works as follows:
+
+1. Lock the resource(s) associated with the metadata being scrubbed.
+   For example, a scan of the refcount btree would lock the AGI and AGF header
+   buffers.
+
+2. If the counter is zero (``xfs_defer_drain_busy`` returns false), there are no
+   chains in progress and the operation may proceed.
+
+3. Otherwise, release the resources grabbed in step 1.
+
+4. Wait for the intent counter to reach zero (``xfs_defer_drain_intents``), then go
+   back to step 1 unless a signal has been caught.
+
+To avoid polling in step 4, the drain provides a waitqueue for scrub threads to
+be woken up whenever the intent count drops to zero.
+
+The proposed patchset is the
+`scrub intent drain series
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=scrub-drain-intents>`_.
+
+.. _jump_labels:
+
+Static Keys (aka Jump Label Patching)
+`````````````````````````````````````
+
+Online fsck for XFS separates the regular filesystem from the checking and
+repair code as much as possible.
+However, there are a few parts of online fsck (such as the intent drains, and
+later, live update hooks) where it is useful for the online fsck code to know
+what's going on in the rest of the filesystem.
+Since it is not expected that online fsck will be constantly running in the
+background, it is very important to minimize the runtime overhead imposed by
+these hooks when online fsck is compiled into the kernel but not actively
+running on behalf of userspace.
+Taking locks in the hot path of a writer thread to access a data structure only
+to find that no further action is necessary is expensive -- on the author's
+computer, this have an overhead of 40-50ns per access.
+Fortunately, the kernel supports dynamic code patching, which enables XFS to
+replace a static branch to hook code with ``nop`` sleds when online fsck isn't
+running.
+This sled has an overhead of however long it takes the instruction decoder to
+skip past the sled, which seems to be on the order of less than 1ns and
+does not access memory outside of instruction fetching.
+
+When online fsck enables the static key, the sled is replaced with an
+unconditional branch to call the hook code.
+The switchover is quite expensive (~22000ns) but is paid entirely by the
+program that invoked online fsck, and can be amortized if multiple threads
+enter online fsck at the same time, or if multiple filesystems are being
+checked at the same time.
+Changing the branch direction requires taking the CPU hotplug lock, and since
+CPU initialization requires memory allocation, online fsck must be careful not
+to change a static key while holding any locks or resources that could be
+accessed in the memory reclaim paths.
+To minimize contention on the CPU hotplug lock, care should be taken not to
+enable or disable static keys unnecessarily.
+
+Because static keys are intended to minimize hook overhead for regular
+filesystem operations when xfs_scrub is not running, the intended usage
+patterns are as follows:
+
+- The hooked part of XFS should declare a static-scoped static key that
+  defaults to false.
+  The ``DEFINE_STATIC_KEY_FALSE`` macro takes care of this.
+  The static key itself should be declared as a ``static`` variable.
+
+- When deciding to invoke code that's only used by scrub, the regular
+  filesystem should call the ``static_branch_unlikely`` predicate to avoid the
+  scrub-only hook code if the static key is not enabled.
+
+- The regular filesystem should export helper functions that call
+  ``static_branch_inc`` to enable and ``static_branch_dec`` to disable the
+  static key.
+  Wrapper functions make it easy to compile out the relevant code if the kernel
+  distributor turns off online fsck at build time.
+
+- Scrub functions wanting to turn on scrub-only XFS functionality should call
+  the ``xchk_fsgates_enable`` from the setup function to enable a specific
+  hook.
+  This must be done before obtaining any resources that are used by memory
+  reclaim.
+  Callers had better be sure they really need the functionality gated by the
+  static key; the ``TRY_HARDER`` flag is useful here.
+
+Online scrub has resource acquisition helpers (e.g. ``xchk_perag_lock``) to
+handle locking AGI and AGF buffers for all scrubber functions.
+If it detects a conflict between scrub and the running transactions, it will
+try to wait for intents to complete.
+If the caller of the helper has not enabled the static key, the helper will
+return -EDEADLOCK, which should result in the scrub being restarted with the
+``TRY_HARDER`` flag set.
+The scrub setup function should detect that flag, enable the static key, and
+try the scrub again.
+Scrub teardown disables all static keys obtained by ``xchk_fsgates_enable``.

+Documentation/staging/static-keys.rst.
+
+.. _xfile:
+
+Pageable Kernel Memory
+----------------------
+
+Some online checking functions work by scanning the filesystem to build a
+shadow copy of an ondisk metadata structure in memory and comparing the two
+copies.
+For online repair to rebuild a metadata structure, it must compute the record
+set that will be stored in the new structure before it can persist that new
+structure to disk.
+Ideally, repairs complete with a single atomic commit that introduces
+a new data structure.
+To meet these goals, the kernel needs to collect a large amount of information
+in a place that doesn't require the correct operation of the filesystem.
+
+Kernel memory isn't suitable because:
+
+* Allocating a contiguous region of memory to create a C array is very
+  difficult, especially on 32-bit systems.
+
+* Linked lists of records introduce double pointer overhead which is very high
+  and eliminate the possibility of indexed lookups.
+
+* Kernel memory is pinned, which can drive the system into OOM conditions.
+
+* The system might not have sufficient memory to stage all the information.
+
+At any given time, online fsck does not need to keep the entire record set in
+memory, which means that individual records can be paged out if necessary.
+Continued development of online fsck demonstrated that the ability to perform
+indexed data storage would also be very useful.
+Fortunately, the Linux kernel already has a facility for byte-addressable and
+pageable storage: tmpfs.
+In-kernel graphics drivers (most notably i915) take advantage of tmpfs files
+to store intermediate data that doesn't need to be in memory at all times, so
+that usage precedent is already established.
+Hence, the ``xfile`` was born!
+

+
+xfile Access Models
+```````````````````
+
+A survey of the intended uses of xfiles suggested these use cases:
+
+1. Arrays of fixed-sized records (space management btrees, directory and
+   extended attribute entries)
+
+2. Sparse arrays of fixed-sized records (quotas and link counts)
+
+3. Large binary objects (BLOBs) of variable sizes (directory and extended
+   attribute names and values)
+
+4. Staging btrees in memory (reverse mapping btrees)
+
+5. Arbitrary contents (realtime space management)
+
+To support the first four use cases, high level data structures wrap the xfile
+to share functionality between online fsck functions.
+The rest of this section discusses the interfaces that the xfile presents to
+four of those five higher level data structures.
+The fifth use case is discussed in the :ref:`realtime summary <rtsummary>` case
+study.
+
+The most general storage interface supported by the xfile enables the reading
+and writing of arbitrary quantities of data at arbitrary offsets in the xfile.
+This capability is provided by ``xfile_pread`` and ``xfile_pwrite`` functions,
+which behave similarly to their userspace counterparts.
+XFS is very record-based, which suggests that the ability to load and store
+complete records is important.
+To support these cases, a pair of ``xfile_obj_load`` and ``xfile_obj_store``
+functions are provided to read and persist objects into an xfile.
+They are internally the same as pread and pwrite, except that they treat any
+error as an out of memory error.
+For online repair, squashing error conditions in this manner is an acceptable
+behavior because the only reaction is to abort the operation back to userspace.
+All five xfile usecases can be serviced by these four functions.
+
+However, no discussion of file access idioms is complete without answering the
+question, "But what about mmap?"
+It is convenient to access storage directly with pointers, just like userspace
+code does with regular memory.
+Online fsck must not drive the system into OOM conditions, which means that
+xfiles must be responsive to memory reclamation.
+tmpfs can only push a pagecache folio to the swap cache if the folio is neither
+pinned nor locked, which means the xfile must not pin too many folios.
+
+Short term direct access to xfile contents is done by locking the pagecache
+folio and mapping it into kernel address space.
+Programmatic access (e.g. pread and pwrite) uses this mechanism.
+Folio locks are not supposed to be held for long periods of time, so long
+term direct access to xfile contents is done by bumping the folio refcount,
+mapping it into kernel address space, and dropping the folio lock.
+These long term users *must* be responsive to memory reclaim by hooking into
+the shrinker infrastructure to know when to release folios.
+
+The ``xfile_get_page`` and ``xfile_put_page`` functions are provided to
+retrieve the (locked) folio that backs part of an xfile and to release it.
+The only code to use these folio lease functions are the xfarray
+:ref:`sorting<xfarray_sort>` algorithms and the :ref:`in-memory
+btrees<xfbtree>`.
+
+xfile Access Coordination
+`````````````````````````
+
+For security reasons, xfiles must be owned privately by the kernel.
+They are marked ``S_PRIVATE`` to prevent interference from the security system,
+must never be mapped into process file descriptor tables, and their pages must
+never be mapped into userspace processes.
+
+To avoid locking recursion issues with the VFS, all accesses to the shmfs file
+are performed by manipulating the page cache directly.
+xfile writers call the ``->write_begin`` and ``->write_end`` functions of the
+xfile's address space to grab writable pages, copy the caller's buffer into the
+page, and release the pages.
+xfile readers call ``shmem_read_mapping_page_gfp`` to grab pages directly
+before copying the contents into the caller's buffer.
+In other words, xfiles ignore the VFS read and write code paths to avoid
+having to create a dummy ``struct kiocb`` and to avoid taking inode and
+freeze locks.
+tmpfs cannot be frozen, and xfiles must not be exposed to userspace.
+
+If an xfile is shared between threads to stage repairs, the caller must provide
+its own locks to coordinate access.
+For example, if a scrub function stores scan results in an xfile and needs
+other threads to provide updates to the scanned data, the scrub function must
+provide a lock for all threads to share.
+
+.. _xfarray:
+
+Arrays of Fixed-Sized Records
+`````````````````````````````
+
+In XFS, each type of indexed space metadata (free space, inodes, reference
+counts, file fork space, and reverse mappings) consists of a set of fixed-size
+records indexed with a classic B+ tree.
+Directories have a set of fixed-size dirent records that point to the names,
+and extended attributes have a set of fixed-size attribute keys that point to
+names and values.
+Quota counters and file link counters index records with numbers.
+During a repair, scrub needs to stage new records during the gathering step and
+retrieve them during the btree building step.
+
+Although this requirement can be satisfied by calling the read and write
+methods of the xfile directly, it is simpler for callers for there to be a
+higher level abstraction to take care of computing array offsets, to provide
+iterator functions, and to deal with sparse records and sorting.
+The ``xfarray`` abstraction presents a linear array for fixed-size records atop
+the byte-accessible xfile.
+
+.. _xfarray_access_patterns:
+
+Array Access Patterns
+^^^^^^^^^^^^^^^^^^^^^
+
+Array access patterns in online fsck tend to fall into three categories.
+Iteration of records is assumed to be necessary for all cases and will be
+covered in the next section.
+
+The first type of caller handles records that are indexed by position.
+Gaps may exist between records, and a record may be updated multiple times
+during the collection step.
+In other words, these callers want a sparse linearly addressed table file.
+The typical use case are quota records or file link count records.
+Access to array elements is performed programmatically via ``xfarray_load`` and
+``xfarray_store`` functions, which wrap the similarly-named xfile functions to
+provide loading and storing of array elements at arbitrary array indices.
+Gaps are defined to be null records, and null records are defined to be a
+sequence of all zero bytes.
+Null records are detected by calling ``xfarray_element_is_null``.
+They are created either by calling ``xfarray_unset`` to null out an existing
+record or by never storing anything to an array index.
+
+The second type of caller handles records that are not indexed by position
+and do not require multiple updates to a record.
+The typical use case here is rebuilding space btrees and key/value btrees.
+These callers can add records to the array without caring about array indices
+via the ``xfarray_append`` function, which stores a record at the end of the
+array.
+For callers that require records to be presentable in a specific order (e.g.
+rebuilding btree data), the ``xfarray_sort`` function can arrange the sorted
+records; this function will be covered later.
+
+The third type of caller is a bag, which is useful for counting records.
+The typical use case here is constructing space extent reference counts from
+reverse mapping information.
+Records can be put in the bag in any order, they can be removed from the bag
+at any time, and uniqueness of records is left to callers.
+The ``xfarray_store_anywhere`` function is used to insert a record in any
+null record slot in the bag; and the ``xfarray_unset`` function removes a
+record from the bag.
+
+The proposed patchset is the
+`big in-memory array
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=big-array>`_.
+
+Iterating Array Elements
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Most users of the xfarray require the ability to iterate the records stored in
+the array.
+Callers can probe every possible array index with the following:
+
+.. code-block:: c
+
+	xfarray_idx_t i;
+	foreach_xfarray_idx(array, i) {
+	    xfarray_load(array, i, &rec);
+
+	    /* do something with rec */
+	}
+
+All users of this idiom must be prepared to handle null records or must already
+know that there aren't any.
+
+For xfarray users that want to iterate a sparse array, the ``xfarray_iter``
+function ignores indices in the xfarray that have never been written to by
+calling ``xfile_seek_data`` (which internally uses ``SEEK_DATA``) to skip areas
+of the array that are not populated with memory pages.
+Once it finds a page, it will skip the zeroed areas of the page.
+
+.. code-block:: c
+
+	xfarray_idx_t i = XFARRAY_CURSOR_INIT;
+	while ((ret = xfarray_iter(array, &i, &rec)) == 1) {
+	    /* do something with rec */
+	}
+
+.. _xfarray_sort:
+
+Sorting Array Elements
+^^^^^^^^^^^^^^^^^^^^^^
+
+During the fourth demonstration of online repair, a community reviewer remarked
+that for performance reasons, online repair ought to load batches of records
+into btree record blocks instead of inserting records into a new btree one at a
+time.
+The btree insertion code in XFS is responsible for maintaining correct ordering
+of the records, so naturally the xfarray must also support sorting the record
+set prior to bulk loading.
+
+Case Study: Sorting xfarrays
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The sorting algorithm used in the xfarray is actually a combination of adaptive
+quicksort and a heapsort subalgorithm in the spirit of
+`Sedgewick <https://algs4.cs.princeton.edu/23quicksort/>`_ and
+`pdqsort <https://github.com/orlp/pdqsort>`_, with customizations for the Linux
+kernel.
+To sort records in a reasonably short amount of time, ``xfarray`` takes
+advantage of the binary subpartitioning offered by quicksort, but it also uses
+heapsort to hedge aginst performance collapse if the chosen quicksort pivots
+are poor.
+Both algorithms are (in general) O(n * lg(n)), but there is a wide performance
+gulf between the two implementations.
+
+The Linux kernel already contains a reasonably fast implementation of heapsort.
+It only operates on regular C arrays, which limits the scope of its usefulness.
+There are two key places where the xfarray uses it:
+
+* Sorting any record subset backed by a single xfile page.
+
+* Loading a small number of xfarray records from potentially disparate parts
+  of the xfarray into a memory buffer, and sorting the buffer.
+
+In other words, ``xfarray`` uses heapsort to constrain the nested recursion of
+quicksort, thereby mitigating quicksort's worst runtime behavior.
+
+Choosing a quicksort pivot is a tricky business.
+A good pivot splits the set to sort in half, leading to the divide and conquer
+behavior that is crucial to  O(n * lg(n)) performance.
+A poor pivot barely splits the subset at all, leading to O(n\ :sup:`2`)
+runtime.
+The xfarray sort routine tries to avoid picking a bad pivot by sampling nine
+records into a memory buffer and using the kernel heapsort to identify the
+median of the nine.
+
+Most modern quicksort implementations employ Tukey's "ninther" to select a
+pivot from a classic C array.
+Typical ninther implementations pick three unique triads of records, sort each
+of the triads, and then sort the middle value of each triad to determine the
+ninther value.
+As stated previously, however, xfile accesses are not entirely cheap.
+It turned out to be much more performant to read the nine elements into a
+memory buffer, run the kernel's in-memory heapsort on the buffer, and choose
+the 4th element of that buffer as the pivot.
+Tukey's ninthers are described in J. W. Tukey, `The ninther, a technique for
+low-effort robust (resistant) location in large samples`, in *Contributions to
+Survey Sampling and Applied Statistics*, edited by H. David, (Academic Press,
+1978), pp. 251–257.
+
+The partitioning of quicksort is fairly textbook -- rearrange the record
+subset around the pivot, then set up the current and next stack frames to
+sort with the larger and the smaller halves of the pivot, respectively.
+This keeps the stack space requirements to log2(record count).
+
+As a final performance optimization, the hi and lo scanning phase of quicksort
+keeps examined xfile pages mapped in the kernel for as long as possible to
+reduce map/unmap cycles.
+Surprisingly, this reduces overall sort runtime by nearly half again after
+accounting for the application of heapsort directly onto xfile pages.
+
+.. _xfblob:
+
+Blob Storage
+````````````
+
+Extended attributes and directories add an additional requirement for staging
+records: arbitrary byte sequences of finite length.
+Each directory entry record needs to store entry name,
+and each extended attribute needs to store both the attribute name and value.
+The names, keys, and values can consume a large amount of memory, so the
+``xfblob`` abstraction was created to simplify management of these blobs
+atop an xfile.
+
+Blob arrays provide ``xfblob_load`` and ``xfblob_store`` functions to retrieve
+and persist objects.
+The store function returns a magic cookie for every object that it persists.
+Later, callers provide this cookie to the ``xblob_load`` to recall the object.
+The ``xfblob_free`` function frees a specific blob, and the ``xfblob_truncate``
+function frees them all because compaction is not needed.
+
+The details of repairing directories and extended attributes will be discussed
+in a subsequent section about atomic extent swapping.
+However, it should be noted that these repair functions only use blob storage
+to cache a small number of entries before adding them to a temporary ondisk
+file, which is why compaction is not required.
+
+The proposed patchset is at the start of the
+`extended attribute repair
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=repair-xattrs>`_ series.
+
+.. _xfbtree:
+
+In-Memory B+Trees
+`````````````````
+
+The chapter about :ref:`secondary metadata<secondary_metadata>` mentioned that
+checking and repairing of secondary metadata commonly requires coordination
+between a live metadata scan of the filesystem and writer threads that are
+updating that metadata.
+Keeping the scan data up to date requires requires the ability to propagate
+metadata updates from the filesystem into the data being collected by the scan.
+This *can* be done by appending concurrent updates into a separate log file and
+applying them before writing the new metadata to disk, but this leads to
+unbounded memory consumption if the rest of the system is very busy.
+Another option is to skip the side-log and commit live updates from the
+filesystem directly into the scan data, which trades more overhead for a lower
+maximum memory requirement.
+In both cases, the data structure holding the scan results must support indexed
+access to perform well.
+
+Given that indexed lookups of scan data is required for both strategies, online
+fsck employs the second strategy of committing live updates directly into
+scan data.
+Because xfarrays are not indexed and do not enforce record ordering, they
+are not suitable for this task.
+Conveniently, however, XFS has a library to create and maintain ordered reverse
+mapping records: the existing rmap btree code!
+If only there was a means to create one in memory.
+
+Recall that the :ref:`xfile <xfile>` abstraction represents memory pages as a
+regular file, which means that the kernel can create byte or block addressable
+virtual address spaces at will.
+The XFS buffer cache specializes in abstracting IO to block-oriented  address
+spaces, which means that adaptation of the buffer cache to interface with
+xfiles enables reuse of the entire btree library.
+Btrees built atop an xfile are collectively known as ``xfbtrees``.
+The next few sections describe how they actually work.
+
+The proposed patchset is the
+`in-memory btree
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=in-memory-btrees>`_
+series.
+
+Using xfiles as a Buffer Cache Target
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Two modifications are necessary to support xfiles as a buffer cache target.
+The first is to make it possible for the ``struct xfs_buftarg`` structure to
+host the ``struct xfs_buf`` rhashtable, because normally those are held by a
+per-AG structure.
+The second change is to modify the buffer ``ioapply`` function to "read" cached
+pages from the xfile and "write" cached pages back to the xfile.
+Multiple access to individual buffers is controlled by the ``xfs_buf`` lock,
+since the xfile does not provide any locking on its own.
+With this adaptation in place, users of the xfile-backed buffer cache use
+exactly the same APIs as users of the disk-backed buffer cache.
+The separation between xfile and buffer cache implies higher memory usage since
+they do not share pages, but this property could some day enable transactional
+updates to an in-memory btree.
+Today, however, it simply eliminates the need for new code.
+
+Space Management with an xfbtree
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Space management for an xfile is very simple -- each btree block is one memory
+page in size.
+These blocks use the same header format as an on-disk btree, but the in-memory
+block verifiers ignore the checksums, assuming that xfile memory is no more
+corruption-prone than regular DRAM.
+Reusing existing code here is more important than absolute memory efficiency.
+
+The very first block of an xfile backing an xfbtree contains a header block.
+The header describes the owner, height, and the block number of the root
+xfbtree block.
+
+To allocate a btree block, use ``xfile_seek_data`` to find a gap in the file.
+If there are no gaps, create one by extending the length of the xfile.
+Preallocate space for the block with ``xfile_prealloc``, and hand back the
+location.
+To free an xfbtree block, use ``xfile_discard`` (which internally uses
+``FALLOC_FL_PUNCH_HOLE``) to remove the memory page from the xfile.
+
+Populating an xfbtree
+^^^^^^^^^^^^^^^^^^^^^
+
+An online fsck function that wants to create an xfbtree should proceed as
+follows:
+
+1. Call ``xfile_create`` to create an xfile.
+
+2. Call ``xfs_alloc_memory_buftarg`` to create a buffer cache target structure
+   pointing to the xfile.
+
+3. Pass the buffer cache target, buffer ops, and other information to
+   ``xfbtree_create`` to write an initial tree header and root block to the
+   xfile.
+   Each btree type should define a wrapper that passes necessary arguments to
+   the creation function.
+   For example, rmap btrees define ``xfs_rmapbt_mem_create`` to take care of
+   all the necessary details for callers.
+   A ``struct xfbtree`` object will be returned.
+
+4. Pass the xfbtree object to the btree cursor creation function for the
+   btree type.
+   Following the example above, ``xfs_rmapbt_mem_cursor`` takes care of this
+   for callers.
+
+5. Pass the btree cursor to the regular btree functions to make queries against
+   and to update the in-memory btree.
+   For example, a btree cursor for an rmap xfbtree can be passed to the
+   ``xfs_rmap_*`` functions just like any other btree cursor.
+   See the :ref:`next section<xfbtree_commit>` for information on dealing with
+   xfbtree updates that are logged to a transaction.
+
+6. When finished, delete the btree cursor, destroy the xfbtree object, free the
+   buffer target, and the destroy the xfile to release all resources.
+
+.. _xfbtree_commit:
+
+Committing Logged xfbtree Buffers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Although it is a clever hack to reuse the rmap btree code to handle the staging
+structure, the ephemeral nature of the in-memory btree block storage presents
+some challenges of its own.
+The XFS transaction manager must not commit buffer log items for buffers backed
+by an xfile because the log format does not understand updates for devices
+other than the data device.
+An ephemeral xfbtree probably will not exist by the time the AIL checkpoints
+log transactions back into the filesystem, and certainly won't exist during
+log recovery.
+For these reasons, any code updating an xfbtree in transaction context must
+remove the buffer log items from the transaction and write the updates into the
+backing xfile before committing or cancelling the transaction.
+
+The ``xfbtree_trans_commit`` and ``xfbtree_trans_cancel`` functions implement
+this functionality as follows:
+
+1. Find each buffer log item whose buffer targets the xfile.
+
+2. Record the dirty/ordered status of the log item.
+
+3. Detach the log item from the buffer.
+
+4. Queue the buffer to a special delwri list.
+
+5. Clear the transaction dirty flag if the only dirty log items were the ones
+   that were detached in step 3.
+
+6. Submit the delwri list to commit the changes to the xfile, if the updates
+   are being committed.
+
+After removing xfile logged buffers from the transaction in this manner, the
+transaction can be committed or cancelled.
+
+Bulk Loading of Ondisk B+Trees
+------------------------------
+
+As mentioned previously, early iterations of online repair built new btree
+structures by creating a new btree and adding observations individually.
+Loading a btree one record at a time had a slight advantage of not requiring
+the incore records to be sorted prior to commit, but was very slow and leaked
+blocks if the system went down during a repair.
+Loading records one at a time also meant that repair could not control the
+loading factor of the blocks in the new btree.
+
+Fortunately, the venerable ``xfs_repair`` tool had a more efficient means for
+rebuilding a btree index from a collection of records -- bulk btree loading.
+This was implemented rather inefficiently code-wise, since ``xfs_repair``
+had separate copy-pasted implementations for each btree type.
+
+To prepare for online fsck, each of the four bulk loaders were studied, notes
+were taken, and the four were refactored into a single generic btree bulk
+loading mechanism.
+Those notes in turn have been refreshed and are presented below.
+
+Geometry Computation
+````````````````````
+
+The zeroth step of bulk loading is to assemble the entire record set that will
+be stored in the new btree, and sort the records.
+Next, call ``xfs_btree_bload_compute_geometry`` to compute the shape of the
+btree from the record set, the type of btree, and any load factor preferences.
+This information is required for resource reservation.
+
+First, the geometry computation computes the minimum and maximum records that
+will fit in a leaf block from the size of a btree block and the size of the
+block header.
+Roughly speaking, the maximum number of records is::
+
+        maxrecs = (block_size - header_size) / record_size
+
+The XFS design specifies that btree blocks should be merged when possible,
+which means the minimum number of records is half of maxrecs::
+
+        minrecs = maxrecs / 2
+
+The next variable to determine is the desired loading factor.
+This must be at least minrecs and no more than maxrecs.
+Choosing minrecs is undesirable because it wastes half the block.
+Choosing maxrecs is also undesirable because adding a single record to each
+newly rebuilt leaf block will cause a tree split, which causes a noticeable
+drop in performance immediately afterwards.
+The default loading factor was chosen to be 75% of maxrecs, which provides a
+reasonably compact structure without any immediate split penalties::
+
+        default_load_factor = (maxrecs + minrecs) / 2
+
+If space is tight, the loading factor will be set to maxrecs to try to avoid
+running out of space::
+
+        leaf_load_factor = enough space ? default_load_factor : maxrecs
+
+Load factor is computed for btree node blocks using the combined size of the
+btree key and pointer as the record size::
+
+        maxrecs = (block_size - header_size) / (key_size + ptr_size)
+        minrecs = maxrecs / 2
+        node_load_factor = enough space ? default_load_factor : maxrecs
+
+Once that's done, the number of leaf blocks required to store the record set
+can be computed as::
+
+        leaf_blocks = ceil(record_count / leaf_load_factor)
+
+The number of node blocks needed to point to the next level down in the tree
+is computed as::
+
+        n_blocks = (n == 0 ? leaf_blocks : node_blocks[n])
+        node_blocks[n + 1] = ceil(n_blocks / node_load_factor)
+
+The entire computation is performed recursively until the current level only
+needs one block.
+The resulting geometry is as follows:
+
+- For AG-rooted btrees, this level is the root level, so the height of the new
+  tree is ``level + 1`` and the space needed is the summation of the number of
+  blocks on each level.
+
+- For inode-rooted btrees where the records in the top level do not fit in the
+  inode fork area, the height is ``level + 2``, the space needed is the
+  summation of the number of blocks on each level, and the inode fork points to
+  the root block.
+
+- For inode-rooted btrees where the records in the top level can be stored in
+  the inode fork area, then the root block can be stored in the inode, the
+  height is ``level + 1``, and the space needed is one less than the summation
+  of the number of blocks on each level.
+  This only becomes relevant when non-bmap btrees gain the ability to root in
+  an inode, which is a future patchset and only included here for completeness.
+
+.. _newbt:
+
+Reserving New B+Tree Blocks
+```````````````````````````
+
+Once repair knows the number of blocks needed for the new btree, it allocates
+those blocks using the free space information.
+Each reserved extent is tracked separately by the btree builder state data.
+To improve crash resilience, the reservation code also logs an Extent Freeing
+Intent (EFI) item in the same transaction as each space allocation and attaches
+its in-memory ``struct xfs_extent_free_item`` object to the space reservation.
+If the system goes down, log recovery will use the unfinished EFIs to free the
+unused space, the free space, leaving the filesystem unchanged.
+
+Each time the btree builder claims a block for the btree from a reserved
+extent, it updates the in-memory reservation to reflect the claimed space.
+Block reservation tries to allocate as much contiguous space as possible to
+reduce the number of EFIs in play.
+
+While repair is writing these new btree blocks, the EFIs created for the space
+reservations pin the tail of the ondisk log.
+It's possible that other parts of the system will remain busy and push the head
+of the log towards the pinned tail.
+To avoid livelocking the filesystem, the EFIs must not pin the tail of the log
+for too long.
+To alleviate this problem, the dynamic relogging capability of the deferred ops
+mechanism is reused here to commit a transaction at the log head containing an
+EFD for the old EFI and new EFI at the head.
+This enables the log to release the old EFI to keep the log moving forwards.
+
+EFIs have a role to play during the commit and reaping phases; please see the
+next section and the section about :ref:`reaping<reaping>` for more details.
+
+Proposed patchsets are the
+`bitmap rework

+
+
+Writing the New Tree
+````````````````````
+
+This part is pretty simple -- the btree builder (``xfs_btree_bulkload``) claims
+a block from the reserved list, writes the new btree block header, fills the
+rest of the block with records, and adds the new leaf block to a list of
+written blocks::
+
+  ┌────┐
+  │leaf│
+  │RRR │
+  └────┘
+
+Sibling pointers are set every time a new block is added to the level::
+
+  ┌────┐ ┌────┐ ┌────┐ ┌────┐
+  │leaf│→│leaf│→│leaf│→│leaf│
+  │RRR │←│RRR │←│RRR │←│RRR │
+  └────┘ └────┘ └────┘ └────┘
+
+When it finishes writing the record leaf blocks, it moves on to the node
+blocks
+To fill a node block, it walks each block in the next level down in the tree
+to compute the relevant keys and write them into the parent node::
+
+      ┌────┐       ┌────┐
+      │node│──────→│node│
+      │PP  │←──────│PP  │
+      └────┘       └────┘
+      ↙   ↘         ↙   ↘
+  ┌────┐ ┌────┐ ┌────┐ ┌────┐
+  │leaf│→│leaf│→│leaf│→│leaf│
+  │RRR │←│RRR │←│RRR │←│RRR │
+  └────┘ └────┘ └────┘ └────┘
+
+When it reaches the root level, it is ready to commit the new btree!::
+
+          ┌─────────┐
+          │  root   │
+          │   PP    │
+          └─────────┘
+          ↙         ↘
+      ┌────┐       ┌────┐
+      │node│──────→│node│
+      │PP  │←──────│PP  │
+      └────┘       └────┘
+      ↙   ↘         ↙   ↘
+  ┌────┐ ┌────┐ ┌────┐ ┌────┐
+  │leaf│→│leaf│→│leaf│→│leaf│
+  │RRR │←│RRR │←│RRR │←│RRR │
+  └────┘ └────┘ └────┘ └────┘
+
+The first step to commit the new btree is to persist the btree blocks to disk
+synchronously.
+This is a little complicated because a new btree block could have been freed
+in the recent past, so the builder must use ``xfs_buf_delwri_queue_here`` to
+remove the (stale) buffer from the AIL list before it can write the new blocks
+to disk.
+Blocks are queued for IO using a delwri list and written in one large batch
+with ``xfs_buf_delwri_submit``.
+
+Once the new blocks have been persisted to disk, control returns to the
+individual repair function that called the bulk loader.
+The repair function must log the location of the new root in a transaction,
+clean up the space reservations that were made for the new btree, and reap the
+old metadata blocks:
+
+1. Commit the location of the new btree root.
+
+2. For each incore reservation:
+
+   a. Log Extent Freeing Done (EFD) items for all the space that was consumed
+      by the btree builder.  The new EFDs must point to the EFIs attached to
+      the reservation to prevent log recovery from freeing the new blocks.
+
+   b. For unclaimed portions of incore reservations, create a regular deferred
+      extent free work item to be free the unused space later in the
+      transaction chain.
+
+   c. The EFDs and EFIs logged in steps 2a and 2b must not overrun the
+      reservation of the committing transaction.
+      If the btree loading code suspects this might be about to happen, it must
+      call ``xrep_defer_finish`` to clear out the deferred work and obtain a
+      fresh transaction.
+
+3. Clear out the deferred work a second time to finish the commit and clean
+   the repair transaction.
+
+The transaction rolling in steps 2c and 3 represent a weakness in the repair
+algorithm, because a log flush and a crash before the end of the reap step can
+result in space leaking.
+Online repair functions minimize the chances of this occuring by using very
+large transactions, which each can accomodate many thousands of block freeing
+instructions.
+Repair moves on to reaping the old blocks, which will be presented in a
+subsequent :ref:`section<reaping>` after a few case studies of bulk loading.
+
+Case Study: Rebuilding the Inode Index
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The high level process to rebuild the inode index btree is:
+
+1. Walk the reverse mapping records to generate ``struct xfs_inobt_rec``
+   records from the inode chunk information and a bitmap of the old inode btree
+   blocks.
+
+2. Append the records to an xfarray in inode order.
+
+3. Use the ``xfs_btree_bload_compute_geometry`` function to compute the number
+   of blocks needed for the inode btree.
+   If the free space inode btree is enabled, call it again to estimate the
+   geometry of the finobt.
+
+4. Allocate the number of blocks computed in the previous step.
+
+5. Use ``xfs_btree_bload`` to write the xfarray records to btree blocks and
+   generate the internal node blocks.
+   If the free space inode btree is enabled, call it again to load the finobt.
+
+6. Commit the location of the new btree root block(s) to the AGI.
+
+7. Reap the old btree blocks using the bitmap created in step 1.
+
+Details are as follows.
+
+The inode btree maps inumbers to the ondisk location of the associated
+inode records, which means that the inode btrees can be rebuilt from the
+reverse mapping information.
+Reverse mapping records with an owner of ``XFS_RMAP_OWN_INOBT`` marks the
+location of the old inode btree blocks.
+Each reverse mapping record with an owner of ``XFS_RMAP_OWN_INODES`` marks the
+location of at least one inode cluster buffer.
+A cluster is the smallest number of ondisk inodes that can be allocated or
+freed in a single transaction; it is never smaller than 1 fs block or 4 inodes.
+
+For the space represented by each inode cluster, ensure that there are no
+records in the free space btrees nor any records in the reference count btree.
+If there are, the space metadata inconsistencies are reason enough to abort the
+operation.
+Otherwise, read each cluster buffer to check that its contents appear to be
+ondisk inodes and to decide if the file is allocated
+(``xfs_dinode.i_mode != 0``) or free (``xfs_dinode.i_mode == 0``).
+Accumulate the results of successive inode cluster buffer reads until there is
+enough information to fill a single inode chunk record, which is 64 consecutive
+numbers in the inumber keyspace.
+If the chunk is sparse, the chunk record may include holes.
+
+Once the repair function accumulates one chunk's worth of data, it calls
+``xfarray_append`` to add the inode btree record to the xfarray.
+This xfarray is walked twice during the btree creation step -- once to populate
+the inode btree with all inode chunk records, and a second time to populate the
+free inode btree with records for chunks that have free non-sparse inodes.
+The number of records for the inode btree is the number of xfarray records,
+but the record count for the free inode btree has to be computed as inode chunk
+records are stored in the xfarray.

+`AG btree repair

+
+Case Study: Rebuilding the Space Reference Counts
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Reverse mapping records are used to rebuild the reference count information.
+Reference counts are required for correct operation of copy on write for shared
+file data.
+Imagine the reverse mapping entries as rectangles representing extents of
+physical blocks, and that the rectangles can be laid down to allow them to
+overlap each other.
+From the diagram below, it is apparent that a reference count record must start
+or end wherever the height of the stack changes.
+In other words, the record emission stimulus is level-triggered::
+
+                        █    ███
+              ██      █████ ████   ███        ██████
+        ██   ████     ███████████ ████     █████████
+        ████████████████████████████████ ███████████
+        ^ ^  ^^ ^^    ^ ^^ ^^^  ^^^^  ^ ^^ ^  ^     ^
+        2 1  23 21    3 43 234  2123  1 01 2  3     0
+
+The ondisk reference count btree does not store the refcount == 0 cases because
+the free space btree already records which blocks are free.
+Extents being used to stage copy-on-write operations should be the only records
+with refcount == 1.
+Single-owner file blocks aren't recorded in either the free space or the
+reference count btrees.
+
+The high level process to rebuild the reference count btree is:
+
+1. Walk the reverse mapping records to generate ``struct xfs_refcount_irec``
+   records for any space having more than one reverse mapping and add them to
+   the xfarray.
+   Any records owned by ``XFS_RMAP_OWN_COW`` are also added to the xfarray
+   because these are extents allocated to stage a copy on write operation and
+   are tracked in the refcount btree.
+
+   Use any records owned by ``XFS_RMAP_OWN_REFC`` to create a bitmap of old
+   refcount btree blocks.
+
+2. Sort the records in physical extent order, putting the CoW staging extents
+   at the end of the xfarray.
+   This matches the sorting order of records in the refcount btree.
+
+3. Use the ``xfs_btree_bload_compute_geometry`` function to compute the number
+   of blocks needed for the new tree.
+
+4. Allocate the number of blocks computed in the previous step.
+
+5. Use ``xfs_btree_bload`` to write the xfarray records to btree blocks and
+   generate the internal node blocks.
+
+6. Commit the location of new btree root block to the AGF.
+
+7. Reap the old btree blocks using the bitmap created in step 1.
+
+Details are as follows; the same algorithm is used by ``xfs_repair`` to
+generate refcount information from reverse mapping records.
+
+- Until the reverse mapping btree runs out of records:
+
+  - Retrieve the next record from the btree and put it in a bag.
+
+  - Collect all records with the same starting block from the btree and put
+    them in the bag.
+
+  - While the bag isn't empty:
+
+    - Among the mappings in the bag, compute the lowest block number where the
+      reference count changes.
+      This position will be either the starting block number of the next
+      unprocessed reverse mapping or the next block after the shortest mapping
+      in the bag.
+
+    - Remove all mappings from the bag that end at this position.
+
+    - Collect all reverse mappings that start at this position from the btree
+      and put them in the bag.
+
+    - If the size of the bag changed and is greater than one, create a new
+      refcount record associating the block number range that we just walked to
+      the size of the bag.
+
+The bag-like structure in this case is a type 2 xfarray as discussed in the
+:ref:`xfarray access patterns<xfarray_access_patterns>` section.
+Reverse mappings are added to the bag using ``xfarray_store_anywhere`` and
+removed via ``xfarray_unset``.
+Bag members are examined through ``xfarray_iter`` loops.
+
+The proposed patchset is the
+`AG btree repair
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=repair-ag-btrees>`_
+series.
+
+Case Study: Rebuilding File Fork Mapping Indices
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The high level process to rebuild a data/attr fork mapping btree is:
+
+1. Walk the reverse mapping records to generate ``struct xfs_bmbt_rec``
+   records from the reverse mapping records for that inode and fork.
+   Append these records to an xfarray.
+   Compute the bitmap of the old bmap btree blocks from the ``BMBT_BLOCK``
+   records.
+
+2. Use the ``xfs_btree_bload_compute_geometry`` function to compute the number
+   of blocks needed for the new tree.
+
+3. Sort the records in file offset order.
+
+4. If the extent records would fit in the inode fork immediate area, commit the
+   records to that immediate area and skip to step 8.
+
+5. Allocate the number of blocks computed in the previous step.
+
+6. Use ``xfs_btree_bload`` to write the xfarray records to btree blocks and
+   generate the internal node blocks.
+
+7. Commit the new btree root block to the inode fork immediate area.
+
+8. Reap the old btree blocks using the bitmap created in step 1.
+
+There are some complications here:
+First, it's possible to move the fork offset to adjust the sizes of the
+immediate areas if the data and attr forks are not both in BMBT format.
+Second, if there are sufficiently few fork mappings, it may be possible to use
+EXTENTS format instead of BMBT, which may require a conversion.
+Third, the incore extent map must be reloaded carefully to avoid disturbing
+any delayed allocation extents.

+.. _reaping:
+
+Reaping Old Metadata Blocks
+---------------------------
+
+Whenever online fsck builds a new data structure to replace one that is
+suspect, there is a question of how to find and dispose of the blocks that
+belonged to the old structure.
+The laziest method of course is not to deal with them at all, but this slowly
+leads to service degradations as space leaks out of the filesystem.
+Hopefully, someone will schedule a rebuild of the free space information to
+plug all those leaks.
+Offline repair rebuilds all space metadata after recording the usage of
+the files and directories that it decides not to clear, hence it can build new
+structures in the discovered free space and avoid the question of reaping.
+
+As part of a repair, online fsck relies heavily on the reverse mapping records
+to find space that is owned by the corresponding rmap owner yet truly free.
+Cross referencing rmap records with other rmap records is necessary because
+there may be other data structures that also think they own some of those
+blocks (e.g. crosslinked trees).
+Permitting the block allocator to hand them out again will not push the system
+towards consistency.
+
+For space metadata, the process of finding extents to dispose of generally
+follows this format:
+
+1. Create a bitmap of space used by data structures that must be preserved.
+   The space reservations used to create the new metadata can be used here if
+   the same rmap owner code is used to denote all of the objects being rebuilt.
+
+2. Survey the reverse mapping data to create a bitmap of space owned by the
+   same ``XFS_RMAP_OWN_*`` number for the metadata that is being preserved.
+
+3. Use the bitmap disunion operator to subtract (1) from (2).
+   The remaining set bits represent candidate extents that could be freed.
+   The process moves on to step 4 below.
+
+Repairs for file-based metadata such as extended attributes, directories,
+symbolic links, quota files and realtime bitmaps are performed by building a
+new structure attached to a temporary file and swapping the forks.
+Afterward, the mappings in the old file fork are the candidate blocks for
+disposal.
+
+The process for disposing of old extents is as follows:
+
+4. For each candidate extent, count the number of reverse mapping records for
+   the first block in that extent that do not have the same rmap owner for the
+   data structure being repaired.
+
+   - If zero, the block has a single owner and can be freed.
+
+   - If not, the block is part of a crosslinked structure and must not be
+     freed.
+
+5. Starting with the next block in the extent, figure out how many more blocks
+   have the same zero/nonzero other owner status as that first block.
+
+6. If the region is crosslinked, delete the reverse mapping entry for the
+   structure being repaired and move on to the next region.
+
+7. If the region is to be freed, mark any corresponding buffers in the buffer
+   cache as stale to prevent log writeback.
+
+8. Free the region and move on.
+
+However, there is one complication to this procedure.
+Transactions are of finite size, so the reaping process must be careful to roll
+the transactions to avoid overruns.
+Overruns come from two sources:
+
+a. EFIs logged on behalf of space that is no longer occupied
+
+b. Log items for buffer invalidations
+
+This is also a window in which a crash during the reaping process can leak
+blocks.
+As stated earlier, online repair functions use very large transactions to
+minimize the chances of this occurring.

+Old reference count and inode btrees are the easiest to reap because they have
+rmap records with special owner codes: ``XFS_RMAP_OWN_REFC`` for the refcount
+btree, and ``XFS_RMAP_OWN_INOBT`` for the inode and free inode btrees.
+Creating a list of extents to reap the old btree blocks is quite simple,
+conceptually:
+
+1. Lock the relevant AGI/AGF header buffers to prevent allocation and frees.
+
+2. For each reverse mapping record with an rmap owner corresponding to the
+   metadata structure being rebuilt, set the corresponding range in a bitmap.
+
+3. Walk the current data structures that have the same rmap owner.
+   For each block visited, clear that range in the above bitmap.
+
+4. Each set bit in the bitmap represents a block that could be a block from the
+   old data structures and hence is a candidate for reaping.
+   In other words, ``(rmap_records_owned_by & ~blocks_reachable_by_walk)``
+   are the blocks that might be freeable.
+
+If it is possible to maintain the AGF lock throughout the repair (which is the
+common case), then step 2 can be performed at the same time as the reverse
+mapping record walk that creates the records for the new btree.
+
+Case Study: Rebuilding the Free Space Indices
+`````````````````````````````````````````````
+
+The high level process to rebuild the free space indices is:
+
+1. Walk the reverse mapping records to generate ``struct xfs_alloc_rec_incore``
+   records from the gaps in the reverse mapping btree.
+
+2. Append the records to an xfarray.
+
+3. Use the ``xfs_btree_bload_compute_geometry`` function to compute the number
+   of blocks needed for each new tree.
+
+4. Allocate the number of blocks computed in the previous step from the free
+   space information collected.
+
+5. Use ``xfs_btree_bload`` to write the xfarray records to btree blocks and
+   generate the internal node blocks for the free space by length index.
+   Call it again for the free space by block number index.
+
+6. Commit the locations of the new btree root blocks to the AGF.
+
+7. Reap the old btree blocks by looking for space that is not recorded by the
+   reverse mapping btree, the new free space btrees, or the AGFL.
+
+Repairing the free space btrees has three key complications over a regular
+btree repair:
+
+First, free space is not explicitly tracked in the reverse mapping records.
+Hence, the new free space records must be inferred from gaps in the physical
+space component of the keyspace of the reverse mapping btree.
+
+Second, free space repairs cannot use the common btree reservation code because
+new blocks are reserved out of the free space btrees.
+This is impossible when repairing the free space btrees themselves.
+However, repair holds the AGF buffer lock for the duration of the free space
+index reconstruction, so it can use the collected free space information to
+supply the blocks for the new free space btrees.
+It is not necessary to back each reserved extent with an EFI because the new
+free space btrees are constructed in what the ondisk filesystem thinks is
+unowned space.
+However, if reserving blocks for the new btrees from the collected free space
+information changes the number of free space records, repair must re-estimate
+the new free space btree geometry with the new record count until the
+reservation is sufficient.
+As part of committing the new btrees, repair must ensure that reverse mappings
+are created for the reserved blocks and that unused reserved blocks are
+inserted into the free space btrees.
+Deferrred rmap and freeing operations are used to ensure that this transition
+is atomic, similar to the other btree repair functions.
+
+Third, finding the blocks to reap after the repair is not overly
+straightforward.
+Blocks for the free space btrees and the reverse mapping btrees are supplied by
+the AGFL.
+Blocks put onto the AGFL have reverse mapping records with the owner
+``XFS_RMAP_OWN_AG``.
+This ownership is retained when blocks move from the AGFL into the free space
+btrees or the reverse mapping btrees.
+When repair walks reverse mapping records to synthesize free space records, it
+creates a bitmap (``ag_owner_bitmap``) of all the space claimed by
+``XFS_RMAP_OWN_AG`` records.
+The repair context maintains a second bitmap corresponding to the rmap btree
+blocks and the AGFL blocks (``rmap_agfl_bitmap``).
+When the walk is complete, the bitmap disunion operation ``(ag_owner_bitmap &
+~rmap_agfl_bitmap)`` computes the extents that are used by the old free space
+btrees.
+These blocks can then be reaped using the methods outlined above.

+Case Study: Reaping After Repairing Reverse Mapping Btrees
+``````````````````````````````````````````````````````````
+
+Old reverse mapping btrees are less difficult to reap after a repair.
+As mentioned in the previous section, blocks on the AGFL, the two free space
+btree blocks, and the reverse mapping btree blocks all have reverse mapping
+records with ``XFS_RMAP_OWN_AG`` as the owner.
+The full process of gathering reverse mapping records and building a new btree
+are described in the case study of
+:ref:`live rebuilds of rmap data <rmap_repair>`, but a crucial point from that
+discussion is that the new rmap btree will not contain any records for the old
+rmap btree, nor will the old btree blocks be tracked in the free space btrees.
+The list of candidate reaping blocks is computed by setting the bits
+corresponding to the gaps in the new rmap btree records, and then clearing the
+bits corresponding to extents in the free space btrees and the current AGFL
+blocks.
+The result ``(new_rmapbt_gaps & ~(agfl | bnobt_records))`` are reaped using the
+methods outlined above.

+```````````````````````````````
+
+The allocation group free block list (AGFL) is repaired as follows:
+
+1. Create a bitmap for all the space that the reverse mapping data claims is
+   owned by ``XFS_RMAP_OWN_AG``.
+
+2. Subtract the space used by the two free space btrees and the rmap btree.
+
+3. Subtract any space that the reverse mapping data claims is owned by any
+   other owner, to avoid re-adding crosslinked blocks to the AGFL.
+
+4. Once the AGFL is full, reap any blocks leftover.
+
+5. The next operation to fix the freelist will right-size the list.

+
+Inode Record Repairs
+--------------------
+
+Inode records must be handled carefully, because they have both ondisk records
+("dinodes") and an in-memory ("cached") representation.
+There is a very high potential for cache coherency issues if online fsck is not
+careful to access the ondisk metadata *only* when the ondisk metadata is so
+badly damaged that the filesystem cannot load the in-memory representation.
+When online fsck wants to open a damaged file for scrubbing, it must use
+specialized resource acquisition functions that return either the in-memory
+representation *or* a lock on whichever object is necessary to prevent any
+update to the ondisk location.
+
+The only repairs that should be made to the ondisk inode buffers are whatever
+is necessary to get the in-core structure loaded.
+This means fixing whatever is caught by the inode cluster buffer and inode fork
+verifiers, and retrying the ``iget`` operation.
+If the second ``iget`` fails, the repair has failed.
+
+Once the in-memory representation is loaded, repair can lock the inode and can
+subject it to comprehensive checks, repairs, and optimizations.
+Most inode attributes are easy to check and constrain, or are user-controlled
+arbitrary bit patterns; these are both easy to fix.
+Dealing with the data and attr fork extent counts and the file block counts is
+more complicated, because computing the correct value requires traversing the
+forks, or if that fails, leaving the fields invalid and waiting for the fork
+fsck functions to run.
+
+The proposed patchset is the
+`inode

+repair series.
+
+Quota Record Repairs
+--------------------
+
+Similar to inodes, quota records ("dquots") also have both ondisk records and
+an in-memory representation, and hence are subject to the same cache coherency
+issues.
+Somewhat confusingly, both are known as dquots in the XFS codebase.
+
+The only repairs that should be made to the ondisk quota record buffers are
+whatever is necessary to get the in-core structure loaded.
+Once the in-memory representation is loaded, the only attributes needing
+checking are obviously bad limits and timer values.
+
+Quota usage counters are checked, repaired, and discussed separately in the
+section about :ref:`live quotacheck <quotacheck>`.

+
+.. _fscounters:
+
+Freezing to Fix Summary Counters
+--------------------------------
+
+Filesystem summary counters track availability of filesystem resources such
+as free blocks, free inodes, and allocated inodes.
+This information could be compiled by walking the free space and inode indexes,
+but this is a slow process, so XFS maintains a copy in the ondisk superblock
+that should reflect the ondisk metadata, at least when the filesystem has been
+unmounted cleanly.
+For performance reasons, XFS also maintains incore copies of those counters,
+which are key to enabling resource reservations for active transactions.
+Writer threads reserve the worst-case quantities of resources from the
+incore counter and give back whatever they don't use at commit time.
+It is therefore only necessary to serialize on the superblock when the
+superblock is being committed to disk.
+
+The lazy superblock counter feature introduced in XFS v5 took this even further
+by training log recovery to recompute the summary counters from the AG headers,
+which eliminated the need for most transactions even to touch the superblock.
+The only time XFS commits the summary counters is at filesystem unmount.
+To reduce contention even further, the incore counter is implemented as a
+percpu counter, which means that each CPU is allocated a batch of blocks from a
+global incore counter and can satisfy small allocations from the local batch.
+
+The high-performance nature of the summary counters makes it difficult for
+online fsck to check them, since there is no way to quiesce a percpu counter
+while the system is running.
+Although online fsck can read the filesystem metadata to compute the correct
+values of the summary counters, there's no way to hold the value of a percpu
+counter stable, so it's quite possible that the counter will be out of date by
+the time the walk is complete.
+Earlier versions of online scrub would return to userspace with an incomplete
+scan flag, but this is not a satisfying outcome for a system administrator.
+For repairs, the in-memory counters must be stabilized while walking the
+filesystem metadata to get an accurate reading and install it in the percpu
+counter.
+
+To satisfy this requirement, online fsck must prevent other programs in the
+system from initiating new writes to the filesystem, it must disable background
+garbage collection threads, and it must wait for existing writer programs to
+exit the kernel.
+Once that has been established, scrub can walk the AG free space indexes, the
+inode btrees, and the realtime bitmap to compute the correct value of all
+four summary counters.
+This is very similar to a filesystem freeze, though not all of the pieces are
+necessary:
+
+- The final freeze state is set one higher than ``SB_FREEZE_COMPLETE`` to
+  prevent other threads from thawing the filesystem, or other scrub threads
+  from initiating another fscounters freeze.
+
+- It does not quiesce the log.
+
+With this code in place, it is now possible to pause the filesystem for just
+long enough to check and correct the summary counters.
+

+| The initial implementation used the actual VFS filesystem freeze         |
+| mechanism to quiesce filesystem activity.                                |
+| With the filesystem frozen, it is possible to resolve the counter values |
+| with exact precision, but there are many problems with calling the VFS   |
+| methods directly:                                                        |
+|                                                                          |
+| - Other programs can unfreeze the filesystem without our knowledge.      |
+|   This leads to incorrect scan results and incorrect repairs.            |
+|                                                                          |
+| - Adding an extra lock to prevent others from thawing the filesystem     |
+|   required the addition of a ``->freeze_super`` function to wrap         |
+|   ``freeze_fs()``.                                                       |
+|   This in turn caused other subtle problems because it turns out that    |
+|   the VFS ``freeze_super`` and ``thaw_super`` functions can drop the     |
+|   last reference to the VFS superblock, and any subsequent access        |
+|   becomes a UAF bug!                                                     |
+|   This can happen if the filesystem is unmounted while the underlying    |
+|   block device has frozen the filesystem.                                |
+|   This problem could be solved by grabbing extra references to the       |
+|   superblock, but it felt suboptimal given the other inadequacies of     |
+|   this approach.                                                         |

+| - The log need not be quiesced to check the summary counters, but a VFS  |
+|   freeze initiates one anyway.                                           |
+|   This adds unnecessary runtime to live fscounter fsck operations.       |
+|                                                                          |
+| - Quiescing the log means that XFS flushes the (possibly incorrect)      |
+|   counters to disk as part of cleaning the log.                          |
+|                                                                          |

+Full Filesystem Scans
+---------------------
+
+Certain types of metadata can only be checked by walking every file in the
+entire filesystem to record observations and comparing the observations against
+what's recorded on disk.
+Like every other type of online repair, repairs are made by writing those
+observations to disk in a replacement structure and committing it atomically.
+However, it is not practical to shut down the entire filesystem to examine
+hundreds of billions of files because the downtime would be excessive.
+Therefore, online fsck must build the infrastructure to manage a live scan of
+all the files in the filesystem.
+There are two questions that need to be solved to perform a live walk:
+
+- How does scrub manage the scan while it is collecting data?
+
+- How does the scan keep abreast of changes being made to the system by other
+  threads?
+

+
+Coordinated Inode Scans
+```````````````````````
+
+In the original Unix filesystems of the 1970s, each directory entry contained
+an index number (*inumber*) which was used as an index into on ondisk array
+(*itable*) of fixed-size records (*inodes*) describing a file's attributes and
+its data block mapping.
+This system is described by J. Lions, `"inode (5659)"
+<http://www.lemis.com/grog/Documentation/Lions/>`_ in *Lions' Commentary on
+UNIX, 6th Edition*, (Dept. of Computer Science, the University of New South
+Wales, November 1977), pp. 18-2; and later by D. Ritchie and K. Thompson,
+`"Implementation of the File System"
+<https://archive.org/details/bstj57-6-1905/page/n8/mode/1up>`_, from *The UNIX
+Time-Sharing System*, (The Bell System Technical Journal, July 1978), pp.
+1913-4.
+
+XFS retains most of this design, except now inumbers are search keys over all
+the space in the data section filesystem.
+They form a continuous keyspace that can be expressed as a 64-bit integer,
+though the inodes themselves are sparsely distributed within the keyspace.
+Scans proceed in a linear fashion across the inumber keyspace, starting from
+``0x0`` and ending at ``0xFFFFFFFFFFFFFFFF``.
+Naturally, a scan through a keyspace requires a scan cursor object to track the
+scan progress.
+Because this keyspace is sparse, this cursor contains two parts.
+The first part of this scan cursor object tracks the inode that will be
+examined next; call this the examination cursor.
+Somewhat less obviously, the scan cursor object must also track which parts of
+the keyspace have already been visited, which is critical for deciding if a
+concurrent filesystem update needs to be incorporated into the scan data.
+Call this the visited inode cursor.
+
+Advancing the scan cursor is a multi-step process encapsulated in
+``xchk_iscan_iter``:
+
+1. Lock the AGI buffer of the AG containing the inode pointed to by the visited
+   inode cursor.
+   This guarantee that inodes in this AG cannot be allocated or freed while
+   advancing the cursor.
+
+2. Use the per-AG inode btree to look up the next inumber after the one that
+   was just visited, since it may not be keyspace adjacent.
+
+3. If there are no more inodes left in this AG:
+
+   a. Move the examination cursor to the point of the inumber keyspace that
+      corresponds to the start of the next AG.
+
+   b. Adjust the visited inode cursor to indicate that it has "visited" the
+      last possible inode in the current AG's inode keyspace.
+      XFS inumbers are segmented, so the cursor needs to be marked as having
+      visited the entire keyspace up to just before the start of the next AG's
+      inode keyspace.
+
+   c. Unlock the AGI and return to step 1 if there are unexamined AGs in the
+      filesystem.
+
+   d. If there are no more AGs to examine, set both cursors to the end of the
+      inumber keyspace.
+      The scan is now complete.
+
+4. Otherwise, there is at least one more inode to scan in this AG:
+
+   a. Move the examination cursor ahead to the next inode marked as allocated
+      by the inode btree.
+
+   b. Adjust the visited inode cursor to point to the inode just prior to where
+      the examination cursor is now.
+      Because the scanner holds the AGI buffer lock, no inodes could have been
+      created in the part of the inode keyspace that the visited inode cursor
+      just advanced.
+
+5. Get the incore inode for the inumber of the examination cursor.
+   By maintaining the AGI buffer lock until this point, the scanner knows that
+   it was safe to advance the examination cursor across the entire keyspace,
+   and that it has stabilized this next inode so that it cannot disappear from
+   the filesystem until the scan releases the incore inode.
+
+6. Drop the AGI lock and return the incore inode to the caller.
+
+Online fsck functions scan all files in the filesystem as follows:
+
+1. Start a scan by calling ``xchk_iscan_start``.
+
+2. Advance the scan cursor (``xchk_iscan_iter``) to get the next inode.
+   If one is provided:
+
+   a. Lock the inode to prevent updates during the scan.
+
+   b. Scan the inode.
+
+   c. While still holding the inode lock, adjust the visited inode cursor
+      (``xchk_iscan_mark_visited``) to point to this inode.
+
+   d. Unlock and release the inode.
+
+8. Call ``xchk_iscan_teardown`` to complete the scan.
+
+There are subtleties with the inode cache that complicate grabbing the incore
+inode for the caller.
+Obviously, it is an absolute requirement that the inode metadata be consistent
+enough to load it into the inode cache.
+Second, if the incore inode is stuck in some intermediate state, the scan
+coordinator must release the AGI and push the main filesystem to get the inode
+back into a loadable state.

+
+Inode Management
+````````````````
+
+In regular filesystem code, references to allocated XFS incore inodes are
+always obtained (``xfs_iget``) outside of transaction context because the
+creation of the incore context for an existing file does not require metadata
+updates.
+However, it is important to note that references to incore inodes obtained as
+part of file creation must be performed in transaction context because the
+filesystem must ensure the atomicity of the ondisk inode btree index updates
+and the initialization of the actual ondisk inode.
+
+References to incore inodes are always released (``xfs_irele``) outside of
+transaction context because there are a handful of activities that might
+require ondisk updates:
+
+- The VFS may decide to kick off writeback as part of a ``DONTCACHE`` inode
+  release.
+
+- Speculative preallocations need to be unreserved.
+
+- An unlinked file may have lost its last reference, in which case the entire
+  file must be inactivated, which involves releasing all of its resources in
+  the ondisk metadata and freeing the inode.
+
+These activities are collectively called inode inactivation.
+Inactivation has two parts -- the VFS part, which initiates writeback on all
+dirty file pages, and the XFS part, which cleans up XFS-specific information
+and frees the inode if it was unlinked.
+If the inode is unlinked (or unconnected after a file handle operation), the
+kernel drops the inode into the inactivation machinery immediately.
+
+During normal operation, resource acquisition for an update follows this order
+to avoid deadlocks:
+
+1. Inode reference (``iget``).
+
+2. Filesystem freeze protection, if repairing (``mnt_want_write_file``).
+
+3. Inode ``IOLOCK`` (VFS ``i_rwsem``) lock to control file IO.
+
+4. Inode ``MMAPLOCK`` (page cache ``invalidate_lock``) lock for operations that
+   can update page cache mappings.
+
+5. Log feature enablement.
+
+6. Transaction log space grant.
+
+7. Space on the data and realtime devices for the transaction.
+
+8. Incore dquot references, if a file is being repaired.
+   Note that they are not locked, merely acquired.
+
+9. Inode ``ILOCK`` for file metadata updates.
+
+10. AG header buffer locks / Realtime metadata inode ILOCK.
+
+11. Realtime metadata buffer locks, if applicable.
+
+12. Extent mapping btree blocks, if applicable.
+
+Resources are often released in the reverse order, though this is not required.
+However, online fsck differs from regular XFS operations because it may examine
+an object that normally is acquired in a later stage of the locking order, and
+then decide to cross-reference the object with an object that is acquired
+earlier in the order.
+The next few sections detail the specific ways in which online fsck takes care
+to avoid deadlocks.
+
+iget and irele During a Scrub
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+An inode scan performed on behalf of a scrub operation runs in transaction
+context, and possibly with resources already locked and bound to it.
+This isn't much of a problem for ``iget`` since it can operate in the context
+of an existing transaction, as long as all of the bound resources are acquired
+before the inode reference in the regular filesystem.
+
+When the VFS ``iput`` function is given a linked inode with no other
+references, it normally puts the inode on an LRU list in the hope that it can
+save time if another process re-opens the file before the system runs out
+of memory and frees it.
+Filesystem callers can short-circuit the LRU process by setting a ``DONTCACHE``
+flag on the inode to cause the kernel to try to drop the inode into the
+inactivation machinery immediately.
+
+In the past, inactivation was always done from the process that dropped the
+inode, which was a problem for scrub because scrub may already hold a
+transaction, and XFS does not support nesting transactions.
+On the other hand, if there is no scrub transaction, it is desirable to drop
+otherwise unused inodes immediately to avoid polluting caches.
+To capture these nuances, the online fsck code has a separate ``xchk_irele``
+function to set or clear the ``DONTCACHE`` flag to get the required release
+behavior.
+
+Proposed patchsets include fixing
+`scrub iget usage

+in a well-known order: parent → child when updating the directory tree, and
+in numerical order of the addresses of their ``struct inode`` object otherwise.
+For regular files, the MMAPLOCK can be acquired after the IOLOCK to stop page
+faults.
+If two MMAPLOCKs must be acquired, they are acquired in numerical order of
+the addresses of their ``struct address_space`` objects.
+Due to the structure of existing filesystem code, IOLOCKs and MMAPLOCKs must be
+acquired before transactions are allocated.
+If two ILOCKs must be acquired, they are acquired in inumber order.
+
+Inode lock acquisition must be done carefully during a coordinated inode scan.
+Online fsck cannot abide these conventions, because for a directory tree
+scanner, the scrub process holds the IOLOCK of the file being scanned and it
+needs to take the IOLOCK of the file at the other end of the directory link.
+If the directory tree is corrupt because it contains a cycle, ``xfs_scrub``
+cannot use the regular inode locking functions and avoid becoming trapped in an
+ABBA deadlock.
+
+Solving both of these problems is straightforward -- any time online fsck
+needs to take a second lock of the same class, it uses trylock to avoid an ABBA
+deadlock.
+If the trylock fails, scrub drops all inode locks and use trylock loops to
+(re)acquire all necessary resources.
+Trylock loops enable scrub to check for pending fatal signals, which is how
+scrub avoids deadlocking the filesystem or becoming an unresponsive process.
+However, trylock loops means that online fsck must be prepared to measure the
+resource being scrubbed before and after the lock cycle to detect changes and
+react accordingly.
+
+.. _dirparent:
+
+Case Study: Finding a Directory Parent
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Consider the directory parent pointer repair code as an example.
+Online fsck must verify that the dotdot dirent of a directory points up to a
+parent directory, and that the parent directory contains exactly one dirent
+pointing down to the child directory.
+Fully validating this relationship (and repairing it if possible) requires a
+walk of every directory on the filesystem while holding the child locked, and
+while updates to the directory tree are being made.
+The coordinated inode scan provides a way to walk the filesystem without the
+possibility of missing an inode.
+The child directory is kept locked to prevent updates to the dotdot dirent, but
+if the scanner fails to lock a parent, it can drop and relock both the child
+and the prospective parent.
+If the dotdot entry changes while the directory is unlocked, then a move or
+rename operation must have changed the child's parentage, and the scan can
+exit early.
+
+The proposed patchset is the
+`directory repair

+series.
+
+.. _fshooks:
+
+Filesystem Hooks
+`````````````````
+
+The second piece of support that online fsck functions need during a full
+filesystem scan is the ability to stay informed about updates being made by
+other threads in the filesystem, since comparisons against the past are useless
+in a dynamic environment.
+Two pieces of Linux kernel infrastructure enable online fsck to monitor regular
+filesystem operations: filesystem hooks and :ref:`static keys<jump_labels>`.
+
+Filesystem hooks convey information about an ongoing filesystem operation to
+a downstream consumer.
+In this case, the downstream consumer is always an online fsck function.
+Because multiple fsck functions can run in parallel, online fsck uses the Linux
+notifier call chain facility to dispatch updates to any number of interested
+fsck processes.
+Call chains are a dynamic list, which means that they can be configured at
+run time.
+Because these hooks are private to the XFS module, the information passed along
+contains exactly what the checking function needs to update its observations.
+
+The current implementation of XFS hooks uses SRCU notifier chains to reduce the
+impact to highly threaded workloads.
+Regular blocking notifier chains use a rwsem and seem to have a much lower
+overhead for single-threaded applications.
+However, it may turn out that the combination of blocking chains and static
+keys are a more performant combination; more study is needed here.
+
+The following pieces are necessary to hook a certain point in the filesystem:
+
+- A ``struct xfs_hooks`` object must be embedded in a convenient place such as
+  a well-known incore filesystem object.
+
+- Each hook must define an action code and a structure containing more context
+  about the action.
+
+- Hook providers should provide appropriate wrapper functions and structs
+  around the ``xfs_hooks`` and ``xfs_hook`` objects to take advantage of type
+  checking to ensure correct usage.
+
+- A callsite in the regular filesystem code must be chosen to call
+  ``xfs_hooks_call`` with the action code and data structure.
+  This place should be adjacent to (and not earlier than) the place where
+  the filesystem update is committed to the transaction.
+  In general, when the filesystem calls a hook chain, it should be able to
+  handle sleeping and should not be vulnerable to memory reclaim or locking
+  recursion.
+  However, the exact requirements are very dependent on the context of the hook
+  caller and the callee.
+
+- The online fsck function should define a structure to hold scan data, a lock
+  to coordinate access to the scan data, and a ``struct xfs_hook`` object.
+  The scanner function and the regular filesystem code must acquire resources
+  in the same order; see the next section for details.
+
+- The online fsck code must contain a C function to catch the hook action code
+  and data structure.
+  If the object being updated has already been visited by the scan, then the
+  hook information must be applied to the scan data.
+
+- Prior to unlocking inodes to start the scan, online fsck must call
+  ``xfs_hooks_setup`` to initialize the ``struct xfs_hook``, and
+  ``xfs_hooks_add`` to enable the hook.
+
+- Online fsck must call ``xfs_hooks_del`` to disable the hook once the scan is
+  complete.
+
+The number of hooks should be kept to a minimum to reduce complexity.
+Static keys are used to reduce the overhead of filesystem hooks to nearly
+zero when online fsck is not running.
+
+.. _liveupdate:
+
+Live Updates During a Scan

+
+The code paths of the online fsck scanning code and the :ref:`hooked<fshooks>`

+
+These rules must be followed to ensure correct interactions between the
+checking code and the code making an update to the filesystem:
+
+- Prior to invoking the notifier call chain, the filesystem function being
+  hooked must acquire the same lock that the scrub scanning function acquires
+  to scan the inode.
+
+- The scanning function and the scrub hook function must coordinate access to
+  the scan data by acquiring a lock on the scan data.
+
+- Scrub hook function must not add the live update information to the scan
+  observations unless the inode being updated has already been scanned.
+  The scan coordinator has a helper predicate (``xchk_iscan_want_live_update``)
+  for this.
+
+- Scrub hook functions must not change the caller's state, including the
+  transaction that it is running.
+  They must not acquire any resources that might conflict with the filesystem
+  function being hooked.
+
+- The hook function can abort the inode scan to avoid breaking the other rules.
+
+The inode scan APIs are pretty simple:
+
+- ``xchk_iscan_start`` starts a scan
+
+- ``xchk_iscan_iter`` grabs a reference to the next inode in the scan or
+  returns zero if there is nothing left to scan
+
+- ``xchk_iscan_want_live_update`` to decide if an inode has already been
+  visited in the scan.
+  This is critical for hook functions to decide if they need to update the
+  in-memory scan information.
+
+- ``xchk_iscan_mark_visited`` to mark an inode as having been visited in the
+  scan
+
+- ``xchk_iscan_teardown`` to finish the scan
+

+
+.. _quotacheck:
+
+Case Study: Quota Counter Checking
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is useful to compare the mount time quotacheck code to the online repair
+quotacheck code.
+Mount time quotacheck does not have to contend with concurrent operations, so
+it does the following:
+
+1. Make sure the ondisk dquots are in good enough shape that all the incore
+   dquots will actually load, and zero the resource usage counters in the
+   ondisk buffer.
+
+2. Walk every inode in the filesystem.
+   Add each file's resource usage to the incore dquot.
+
+3. Walk each incore dquot.
+   If the incore dquot is not being flushed, add the ondisk buffer backing the
+   incore dquot to a delayed write (delwri) list.
+
+4. Write the buffer list to disk.
+
+Like most online fsck functions, online quotacheck can't write to regular
+filesystem objects until the newly collected metadata reflect all filesystem
+state.
+Therefore, online quotacheck records file resource usage to a shadow dquot
+index implemented with a sparse ``xfarray``, and only writes to the real dquots
+once the scan is complete.
+Handling transactional updates is tricky because quota resource usage updates
+are handled in phases to minimize contention on dquots:
+
+1. The inodes involved are joined and locked to a transaction.
+
+2. For each dquot attached to the file:
+
+   a. The dquot is locked.
+
+   b. A quota reservation is added to the dquot's resource usage.
+      The reservation is recorded in the transaction.
+
+   c. The dquot is unlocked.
+
+3. Changes in actual quota usage are tracked in the transaction.
+
+4. At transaction commit time, each dquot is examined again:
+
+   a. The dquot is locked again.
+
+   b. Quota usage changes are logged and unused reservation is given back to
+      the dquot.
+
+   c. The dquot is unlocked.
+
+For online quotacheck, hooks are placed in steps 2 and 4.
+The step 2 hook creates a shadow version of the transaction dquot context
+(``dqtrx``) that operates in a similar manner to the regular code.
+The step 4 hook commits the shadow ``dqtrx`` changes to the shadow dquots.
+Notice that both hooks are called with the inode locked, which is how the
+live update coordinates with the inode scanner.
+
+The quotacheck scan looks like this:
+
+1. Set up a coordinated inode scan.
+
+2. For each inode returned by the inode scan iterator:
+
+   a. Grab and lock the inode.
+
+   b. Determine that inode's resource usage (data blocks, inode counts,
+      realtime blocks) and add that to the shadow dquots for the user, group,
+      and project ids associated with the inode.
+
+   c. Unlock and release the inode.
+
+3. For each dquot in the system:
+
+   a. Grab and lock the dquot.
+
+   b. Check the dquot against the shadow dquots created by the scan and updated
+      by the live hooks.
+
+Live updates are key to being able to walk every quota record without
+needing to hold any locks for a long duration.
+If repairs are desired, the real and shadow dquots are locked and their
+resource counts are set to the values in the shadow dquot.
+
+The proposed patchset is the
+`online quotacheck
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=repair-quotacheck>`_
+series.
+
+.. _nlinks:
+
+Case Study: File Link Count Checking
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+File link count checking also uses live update hooks.
+The coordinated inode scanner is used to visit all directories on the
+filesystem, and per-file link count records are stored in a sparse ``xfarray``
+indexed by inumber.
+During the scanning phase, each entry in a directory generates observation
+data as follows:
+
+1. If the entry is a dotdot (``'..'``) entry of the root directory, the
+   directory's parent link count is bumped because the root directory's dotdot
+   entry is self referential.
+
+2. If the entry is a dotdot entry of a subdirectory, the parent's backref
+   count is bumped.
+
+3. If the entry is neither a dot nor a dotdot entry, the target file's parent
+   count is bumped.
+
+4. If the target is a subdirectory, the parent's child link count is bumped.
+
+A crucial point to understand about how the link count inode scanner interacts
+with the live update hooks is that the scan cursor tracks which *parent*
+directories have been scanned.
+In other words, the live updates ignore any update about ``A → B`` when A has
+not been scanned, even if B has been scanned.
+Furthermore, a subdirectory A with a dotdot entry pointing back to B is
+accounted as a backref counter in the shadow data for A, since child dotdot
+entries affect the parent's link count.
+Live update hooks are carefully placed in all parts of the filesystem that
+create, change, or remove directory entries, since those operations involve
+bumplink and droplink.
+
+For any file, the correct link count is the number of parents plus the number
+of child subdirectories.
+Non-directories never have children of any kind.
+The backref information is used to detect inconsistencies in the number of
+links pointing to child subdirectories and the number of dotdot entries
+pointing back.
+
+After the scan completes, the link count of each file can be checked by locking
+both the inode and the shadow data, and comparing the link counts.
+A second coordinated inode scan cursor is used for comparisons.
+Live updates are key to being able to walk every inode without needing to hold
+any locks between inodes.
+If repairs are desired, the inode's link count is set to the value in the
+shadow information.
+If no parents are found, the file must be :ref:`reparented <orphanage>` to the
+orphanage to prevent the file from being lost forever.
+
+The proposed patchset is the
+`file link count repair
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=scrub-nlinks>`_
+series.
+
+.. _rmap_repair:
+
+Case Study: Rebuilding Reverse Mapping Records
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Most repair functions follow the same pattern: lock filesystem resources,
+walk the surviving ondisk metadata looking for replacement metadata records,
+and use an :ref:`in-memory array <xfarray>` to store the gathered observations.
+The primary advantage of this approach is the simplicity and modularity of the
+repair code -- code and data are entirely contained within the scrub module,
+do not require hooks in the main filesystem, and are usually the most efficient
+in memory use.
+A secondary advantage of this repair approach is atomicity -- once the kernel
+decides a structure is corrupt, no other threads can access the metadata until
+the kernel finishes repairing and revalidating the metadata.
+
+For repairs going on within a shard of the filesystem, these advantages
+outweigh the delays inherent in locking the shard while repairing parts of the
+shard.
+Unfortunately, repairs to the reverse mapping btree cannot use the "standard"
+btree repair strategy because it must scan every space mapping of every fork of
+every file in the filesystem, and the filesystem cannot stop.
+Therefore, rmap repair foregoes atomicity between scrub and repair.
+It combines a :ref:`coordinated inode scanner <iscan>`, :ref:`live update hooks
+<liveupdate>`, and an :ref:`in-memory rmap btree <xfbtree>` to complete the
+scan for reverse mapping records.
+
+1. Set up an xfbtree to stage rmap records.
+
+2. While holding the locks on the AGI and AGF buffers acquired during the
+   scrub, generate reverse mappings for all AG metadata: inodes, btrees, CoW
+   staging extents, and the internal log.
+
+3. Set up an inode scanner.
+
+4. Hook into rmap updates for the AG being repaired so that the live scan data
+   can receive updates to the rmap btree from the rest of the filesystem during
+   the file scan.
+
+5. For each space mapping found in either fork of each file scanned,
+   decide if the mapping matches the AG of interest.
+   If so:
+
+   a. Create a btree cursor for the in-memory btree.
+
+   b. Use the rmap code to add the record to the in-memory btree.
+
+   c. Use the :ref:`special commit function <xfbtree_commit>` to write the
+      xfbtree changes to the xfile.
+
+6. For each live update received via the hook, decide if the owner has already
+   been scanned.
+   If so, apply the live update into the scan data:
+
+   a. Create a btree cursor for the in-memory btree.
+
+   b. Replay the operation into the in-memory btree.
+
+   c. Use the :ref:`special commit function <xfbtree_commit>` to write the
+      xfbtree changes to the xfile.
+      This is performed with an empty transaction to avoid changing the
+      caller's state.
+
+7. When the inode scan finishes, create a new scrub transaction and relock the
+   two AG headers.
+
+8. Compute the new btree geometry using the number of rmap records in the
+   shadow btree, like all other btree rebuilding functions.
+
+9. Allocate the number of blocks computed in the previous step.
+
+10. Perform the usual btree bulk loading and commit to install the new rmap
+    btree.
+
+11. Reap the old rmap btree blocks as discussed in the case study about how
+    to :ref:`reap after rmap btree repair <rmap_reap>`.
+
+12. Free the xfbtree now that it not needed.

+
+Staging Repairs with Temporary Files on Disk
+--------------------------------------------
+
+XFS stores a substantial amount of metadata in file forks: directories,
+extended attributes, symbolic link targets, free space bitmaps and summary
+information for the realtime volume, and quota records.
+File forks map 64-bit logical file fork space extents to physical storage space
+extents, similar to how a memory management unit maps 64-bit virtual addresses
+to physical memory addresses.
+Therefore, file-based tree structures (such as directories and extended
+attributes) use blocks mapped in the file fork offset address space that point
+to other blocks mapped within that same address space, and file-based linear
+structures (such as bitmaps and quota records) compute array element offsets in
+the file fork offset address space.
+
+Because file forks can consume as much space as the entire filesystem, repairs
+cannot be staged in memory, even when a paging scheme is available.
+Therefore, online repair of file-based metadata createas a temporary file in
+the XFS filesystem, writes a new structure at the correct offsets into the
+temporary file, and atomically swaps the fork mappings (and hence the fork
+contents) to commit the repair.
+Once the repair is complete, the old fork can be reaped as necessary; if the
+system goes down during the reap, the iunlink code will delete the blocks
+during log recovery.
+
+**Note**: All space usage and inode indices in the filesystem *must* be
+consistent to use a temporary file safely!
+This dependency is the reason why online repair can only use pageable kernel
+memory to stage ondisk space usage information.
+
+Swapping metadata extents with a temporary file requires the owner field of the
+block headers to match the file being repaired and not the temporary file.  The
+directory, extended attribute, and symbolic link functions were all modified to
+allow callers to specify owner numbers explicitly.
+
+There is a downside to the reaping process -- if the system crashes during the
+reap phase and the fork extents are crosslinked, the iunlink processing will
+fail because freeing space will find the extra reverse mappings and abort.
+
+Temporary files created for repair are similar to ``O_TMPFILE`` files created
+by userspace.
+They are not linked into a directory and the entire file will be reaped when
+the last reference to the file is lost.
+The key differences are that these files must have no access permission outside
+the kernel at all, they must be specially marked to prevent them from being
+opened by handle, and they must never be linked into the directory tree.

+| In the initial iteration of file metadata repair, the damaged metadata   |

+| fork would be reaped; and then a new structure would be built in its     |
+| place.                                                                   |

+| The second iteration explored building a second structure at a high      |

+| using a ``COLLAPSE_RANGE`` operation to slide the new extents into       |

+| - Array structures are linearly addressed, and the regular filesystem    |

+| - Even if repair could build an alternate copy of a data structure in a  |

+| - A crash after construction of the secondary tree but before the range  |

+|   in the header area of each block.                                      |
+|   An atomic range collapse operation would have to rewrite this part of  |
+|   each block header.                                                     |
+|   Rewriting a single field in block headers is not a huge problem, but   |
+|   it's something to be aware of.                                         |
+|                                                                          |
+| - Each block in a directory or extended attributes btree index contains  |
+|   sibling and child block pointers.                                      |
+|   Were the atomic commit to use a range collapse operation, each block   |
+|   would have to be rewritten very carefully to preserve the graph        |
+|   structure.                                                             |
+|   Doing this as part of a range collapse means rewriting a large number  |
+|   of blocks repeatedly, which is not conducive to quick repairs.         |
+|                                                                          |
+| This lead to the introduction of temporary file staging.                 |
++--------------------------------------------------------------------------+
+
+Using a Temporary File
+``````````````````````
+
+Online repair code should use the ``xrep_tempfile_create`` function to create a
+temporary file inside the filesystem.
+This allocates an inode, marks the in-core inode private, and attaches it to
+the scrub context.
+These files are hidden from userspace, may not be added to the directory tree,
+and must be kept private.
+
+Temporary files only use two inode locks: the IOLOCK and the ILOCK.
+The MMAPLOCK is not needed here, because there must not be page faults from
+userspace for data fork blocks.
+The usage patterns of these two locks are the same as for any other XFS file --
+access to file data are controlled via the IOLOCK, and access to file metadata
+are controlled via the ILOCK.
+Locking helpers are provided so that the temporary file and its lock state can
+be cleaned up by the scrub context.
+To comply with the nested locking strategy laid out in the :ref:`inode
+locking<ilocking>` section, it is recommended that scrub functions use the
+xrep_tempfile_ilock*_nowait lock helpers.
+
+Data can be written to a temporary file by two means:
+
+1. ``xrep_tempfile_copyin`` can be used to set the contents of a regular
+   temporary file from an xfile.
+
+2. The regular directory, symbolic link, and extended attribute functions can
+   be used to write to the temporary file.
+
+Once a good copy of a data file has been constructed in a temporary file, it
+must be conveyed to the file being repaired, which is the topic of the next
+section.
+
+The proposed patches are in the
+`repair temporary files
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=repair-tempfiles>`_
+series.
+
+Atomic Extent Swapping
+----------------------
+
+Once repair builds a temporary file with a new data structure written into
+it, it must commit the new changes into the existing file.
+It is not possible to swap the inumbers of two files, so instead the new
+metadata must replace the old.
+This suggests the need for the ability to swap extents, but the existing extent
+swapping code used by the file defragmenting tool ``xfs_fsr`` is not sufficient
+for online repair because:
+
+a. When the reverse-mapping btree is enabled, the swap code must keep the
+   reverse mapping information up to date with every exchange of mappings.
+   Therefore, it can only exchange one mapping per transaction, and each
+   transaction is independent.
+
+b. Reverse-mapping is critical for the operation of online fsck, so the old
+   defragmentation code (which swapped entire extent forks in a single
+   operation) is not useful here.
+
+c. Defragmentation is assumed to occur between two files with identical
+   contents.
+   For this use case, an incomplete exchange will not result in a user-visible
+   change in file contents, even if the operation is interrupted.
+
+d. Online repair needs to swap the contents of two files that are by definition
+   *not* identical.
+   For directory and xattr repairs, the user-visible contents might be the
+   same, but the contents of individual blocks may be very different.
+
+e. Old blocks in the file may be cross-linked with another structure and must
+   not reappear if the system goes down mid-repair.
+
+These problems are overcome by creating a new deferred operation and a new type
+of log intent item to track the progress of an operation to exchange two file
+ranges.
+The new deferred operation type chains together the same transactions used by
+the reverse-mapping extent swap code.
+The new log item records the progress of the exchange to ensure that once an
+exchange begins, it will always run to completion, even there are
+interruptions.
+The new ``XFS_SB_FEAT_INCOMPAT_LOG_ATOMIC_SWAP`` log-incompatible feature flag
+in the superblock protects these new log item records from being replayed on
+old kernels.
+
+The proposed patchset is the
+`atomic extent swap
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=atomic-file-updates>`_
+series.

++--------------------------------------------------------------------------+
+| **Sidebar: Using Log-Incompatible Feature Flags**                        |
++--------------------------------------------------------------------------+
+| Starting with XFS v5, the superblock contains a                          |
+| ``sb_features_log_incompat`` field to indicate that the log contains     |
+| records that might not readable by all kernels that could mount this     |
+| filesystem.                                                              |
+| In short, log incompat features protect the log contents against kernels |
+| that will not understand the contents.                                   |
+| Unlike the other superblock feature bits, log incompat bits are          |
+| ephemeral because an empty (clean) log does not need protection.         |
+| The log cleans itself after its contents have been committed into the    |
+| filesystem, either as part of an unmount or because the system is        |
+| otherwise idle.                                                          |
+| Because upper level code can be working on a transaction at the same     |
+| time that the log cleans itself, it is necessary for upper level code to |
+| communicate to the log when it is going to use a log incompatible        |
+| feature.                                                                 |
+|                                                                          |
+| The log coordinates access to incompatible features through the use of   |
+| one ``struct rw_semaphore`` for each feature.                            |
+| The log cleaning code tries to take this rwsem in exclusive mode to      |
+| clear the bit; if the lock attempt fails, the feature bit remains set.   |
+| Filesystem code signals its intention to use a log incompat feature in a |
+| transaction by calling ``xlog_use_incompat_feat``, which takes the rwsem |
+| in shared mode.                                                          |
+| The code supporting a log incompat feature should create wrapper         |
+| functions to obtain the log feature and call                             |
+| ``xfs_add_incompat_log_feature`` to set the feature bits in the primary  |
+| superblock.                                                              |
+| The superblock update is performed transactionally, so the wrapper to    |
+| obtain log assistance must be called just prior to the creation of the   |
+| transaction that uses the functionality.                                 |
+| For a file operation, this step must happen after taking the IOLOCK      |
+| and the MMAPLOCK, but before allocating the transaction.                 |
+| When the transaction is complete, the ``xlog_drop_incompat_feat``        |
+| function is called to release the feature.                               |
+| The feature bit will not be cleared from the superblock until the log    |
+| becomes clean.                                                           |
+|                                                                          |
+| Log-assisted extended attribute updates and atomic extent swaps both use |
+| log incompat features and provide convenience wrappers around the        |
+| functionality.                                                           |

+
+Mechanics of an Atomic Extent Swap
+``````````````````````````````````
+
+Swapping entire file forks is a complex task.
+The goal is to exchange all file fork mappings between two file fork offset
+ranges.
+There are likely to be many extent mappings in each fork, and the edges of
+the mappings aren't necessarily aligned.
+Furthermore, there may be other updates that need to happen after the swap,
+such as exchanging file sizes, inode flags, or conversion of fork data to local
+format.
+This is roughly the format of the new deferred extent swap work item:
+
+.. code-block:: c
+
+	struct xfs_swapext_intent {
+	    /* Inodes participating in the operation. */
+	    struct xfs_inode    *sxi_ip1;
+	    struct xfs_inode    *sxi_ip2;
+
+	    /* File offset range information. */
+	    xfs_fileoff_t       sxi_startoff1;
+	    xfs_fileoff_t       sxi_startoff2;
+	    xfs_filblks_t       sxi_blockcount;
+
+	    /* Set these file sizes after the operation, unless negative. */
+	    xfs_fsize_t         sxi_isize1;
+	    xfs_fsize_t         sxi_isize2;
+
+	    /* XFS_SWAP_EXT_* log operation flags */
+	    uint64_t            sxi_flags;
+	};
+
+The new log intent item contains enough information to track two logical fork
+offset ranges: ``(inode1, startoff1, blockcount)`` and ``(inode2, startoff2,
+blockcount)``.
+Each step of a swap operation exchanges the largest file range mapping possible
+from one file to the other.
+After each step in the swap operation, the two startoff fields are incremented
+and the blockcount field is decremented to reflect the progress made.
+The flags field captures behavioral parameters such as swapping the attr fork
+instead of the data fork and other work to be done after the extent swap.
+The two isize fields are used to swap the file size at the end of the operation
+if the file data fork is the target of the swap operation.
+
+When the extent swap is initiated, the sequence of operations is as follows:
+
+1. Create a deferred work item for the extent swap.
+   At the start, it should contain the entirety of the file ranges to be
+   swapped.
+
+2. Call ``xfs_defer_finish`` to process the exchange.
+   This is encapsulated in ``xrep_tempswap_contents`` for scrub operations.
+   This will log an extent swap intent item to the transaction for the deferred
+   extent swap work item.
+
+3. Until ``sxi_blockcount`` of the deferred extent swap work item is zero,
+
+   a. Read the block maps of both file ranges starting at ``sxi_startoff1`` and
+      ``sxi_startoff2``, respectively, and compute the longest extent that can
+      be swapped in a single step.
+      This is the minimum of the two ``br_blockcount`` s in the mappings.
+      Keep advancing through the file forks until at least one of the mappings
+      contains written blocks.
+      Mutual holes, unwritten extents, and extent mappings to the same physical
+      space are not exchanged.
+
+      For the next few steps, this document will refer to the mapping that came
+      from file 1 as "map1", and the mapping that came from file 2 as "map2".
+
+   b. Create a deferred block mapping update to unmap map1 from file 1.
+
+   c. Create a deferred block mapping update to unmap map2 from file 2.
+
+   d. Create a deferred block mapping update to map map1 into file 2.
+
+   e. Create a deferred block mapping update to map map2 into file 1.
+
+   f. Log the block, quota, and extent count updates for both files.
+
+   g. Extend the ondisk size of either file if necessary.
+
+   h. Log an extent swap done log item for the extent swap intent log item
+      that was read at the start of step 3.
+
+   i. Compute the amount of file range that has just been covered.
+      This quantity is ``(map1.br_startoff + map1.br_blockcount -
+      sxi_startoff1)``, because step 3a could have skipped holes.
+
+   j. Increase the starting offsets of ``sxi_startoff1`` and ``sxi_startoff2``
+      by the number of blocks computed in the previous step, and decrease
+      ``sxi_blockcount`` by the same quantity.
+      This advances the cursor.
+
+   k. Log a new extent swap intent log item reflecting the advanced state of
+      the work item.
+
+   l. Return the proper error code (EAGAIN) to the deferred operation manager
+      to inform it that there is more work to be done.
+      The operation manager completes the deferred work in steps 3b-3e before
+      moving back to the start of step 3.
+
+4. Perform any post-processing.
+   This will be discussed in more detail in subsequent sections.
+
+If the filesystem goes down in the middle of an operation, log recovery will
+find the most recent unfinished extent swap log intent item and restart from
+there.
+This is how extent swapping guarantees that an outside observer will either see
+the old broken structure or the new one, and never a mismash of both.
+
+Preparation for Extent Swapping
+```````````````````````````````
+
+There are a few things that need to be taken care of before initiating an
+atomic extent swap operation.
+First, regular files require the page cache to be flushed to disk before the
+operation begins, and directio writes to be quiesced.
+Like any filesystem operation, extent swapping must determine the maximum
+amount of disk space and quota that can be consumed on behalf of both files in
+the operation, and reserve that quantity of resources to avoid an unrecoverable
+out of space failure once it starts dirtying metadata.
+The preparation step scans the ranges of both files to estimate:
+
+- Data device blocks needed to handle the repeated updates to the fork
+  mappings.
+- Change in data and realtime block counts for both files.
+- Increase in quota usage for both files, if the two files do not share the
+  same set of quota ids.
+- The number of extent mappings that will be added to each file.
+- Whether or not there are partially written realtime extents.
+  User programs must never be able to access a realtime file extent that maps
+  to different extents on the realtime volume, which could happen if the
+  operation fails to run to completion.
+
+The need for precise estimation increases the run time of the swap operation,
+but it is very important to maintain correct accounting.
+The filesystem must not run completely out of free space, nor can the extent
+swap ever add more extent mappings to a fork than it can support.
+Regular users are required to abide the quota limits, though metadata repairs
+may exceed quota to resolve inconsistent metadata elsewhere.
+
+Special Features for Swapping Metadata File Extents
+```````````````````````````````````````````````````
+
+Extended attributes, symbolic links, and directories can set the fork format to
+"local" and treat the fork as a literal area for data storage.
+Metadata repairs must take extra steps to support these cases:
+
+- If both forks are in local format and the fork areas are large enough, the
+  swap is performed by copying the incore fork contents, logging both forks,
+  and committing.
+  The atomic extent swap mechanism is not necessary, since this can be done
+  with a single transaction.
+
+- If both forks map blocks, then the regular atomic extent swap is used.
+
+- Otherwise, only one fork is in local format.
+  The contents of the local format fork are converted to a block to perform the
+  swap.
+  The conversion to block format must be done in the same transaction that
+  logs the initial extent swap intent log item.
+  The regular atomic extent swap is used to exchange the mappings.
+  Special flags are set on the swap operation so that the transaction can be
+  rolled one more time to convert the second file's fork back to local format
+  so that the second file will be ready to go as soon as the ILOCK is dropped.
+
+Extended attributes and directories stamp the owning inode into every block,
+but the buffer verifiers do not actually check the inode number!
+Although there is no verification, it is still important to maintain
+referential integrity, so prior to performing the extent swap, online repair
+builds every block in the new data structure with the owner field of the file
+being repaired.
+
+After a successful swap operation, the repair operation must reap the old fork
+blocks by processing each fork mapping through the standard :ref:`file extent
+reaping <reaping>` mechanism that is done post-repair.
+If the filesystem should go down during the reap part of the repair, the
+iunlink processing at the end of recovery will free both the temporary file and
+whatever blocks were not reaped.
+However, this iunlink processing omits the cross-link detection of online
+repair, and is not completely foolproof.
+
+Swapping Temporary File Extents
+```````````````````````````````
+
+To repair a metadata file, online repair proceeds as follows:
+
+1. Create a temporary repair file.
+
+2. Use the staging data to write out new contents into the temporary repair
+   file.
+   The same fork must be written to as is being repaired.
+
+3. Commit the scrub transaction, since the swap estimation step must be
+   completed before transaction reservations are made.
+
+4. Call ``xrep_tempswap_trans_alloc`` to allocate a new scrub transaction with
+   the appropriate resource reservations, locks, and fill out a ``struct
+   xfs_swapext_req`` with the details of the swap operation.
+
+5. Call ``xrep_tempswap_contents`` to swap the contents.
+
+6. Commit the transaction to complete the repair.

+
+Case Study: Repairing the Realtime Summary File
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In the "realtime" section of an XFS filesystem, free space is tracked via a
+bitmap, similar to Unix FFS.
+Each bit in the bitmap represents one realtime extent, which is a multiple of
+the filesystem block size between 4KiB and 1GiB in size.
+The realtime summary file indexes the number of free extents of a given size to
+the offset of the block within the realtime free space bitmap where those free
+extents begin.
+In other words, the summary file helps the allocator find free extents by
+length, similar to what the free space by count (cntbt) btree does for the data
+section.
+
+The summary file itself is a flat file (with no block headers or checksums!)
+partitioned into ``log2(total rt extents)`` sections containing enough 32-bit
+counters to match the number of blocks in the rt bitmap.
+Each counter records the number of free extents that start in that bitmap block
+and can satisfy a power-of-two allocation request.
+
+To check the summary file against the bitmap:
+
+1. Take the ILOCK of both the realtime bitmap and summary files.
+
+2. For each free space extent recorded in the bitmap:
+
+   a. Compute the position in the summary file that contains a counter that
+      represents this free extent.
+
+   b. Read the counter from the xfile.
+
+   c. Increment it, and write it back to the xfile.
+
+3. Compare the contents of the xfile against the ondisk file.
+
+To repair the summary file, write the xfile contents into the temporary file
+and use atomic extent swap to commit the new contents.
+The temporary file is then reaped.
+
+The proposed patchset is the
+`realtime summary repair

+series.
+
+Case Study: Salvaging Extended Attributes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In XFS, extended attributes are implemented as a namespaced name-value store.
+Values are limited in size to 64KiB, but there is no limit in the number of
+names.
+The attribute fork is unpartitioned, which means that the root of the attribute
+structure is always in logical block zero, but attribute leaf blocks, dabtree
+index blocks, and remote value blocks are intermixed.
+Attribute leaf blocks contain variable-sized records that associate
+user-provided names with the user-provided values.
+Values larger than a block are allocated separate extents and written there.
+If the leaf information expands beyond a single block, a directory/attribute
+btree (``dabtree``) is created to map hashes of attribute names to entries
+for fast lookup.
+
+Salvaging extended attributes is done as follows:
+
+1. Walk the attr fork mappings of the file being repaired to find the attribute
+   leaf blocks.
+   When one is found,
+
+   a. Walk the attr leaf block to find candidate keys.
+      When one is found,
+
+      1. Check the name for problems, and ignore the name if there are.
+
+      2. Retrieve the value.
+         If that succeeds, add the name and value to the staging xfarray and
+         xfblob.
+
+2. If the memory usage of the xfarray and xfblob exceed a certain amount of
+   memory or there are no more attr fork blocks to examine, unlock the file and
+   add the staged extended attributes to the temporary file.
+
+3. Use atomic extent swapping to exchange the new and old extended attribute
+   structures.
+   The old attribute blocks are now attached to the temporary file.
+
+4. Reap the temporary file.

+The proposed patchset is the
+`extended attribute repair

+
+Fixing Directories
+------------------
+
+Fixing directories is difficult with currently available filesystem features,
+since directory entries are not redundant.
+The offline repair tool scans all inodes to find files with nonzero link count,
+and then it scans all directories to establish parentage of those linked files.
+Damaged files and directories are zapped, and files with no parent are
+moved to the ``/lost+found`` directory.
+It does not try to salvage anything.
+
+The best that online repair can do at this time is to read directory data
+blocks and salvage any dirents that look plausible, correct link counts, and
+move orphans back into the directory tree.
+The salvage process is discussed in the case study at the end of this section.
+The :ref:`file link count fsck <nlinks>` code takes care of fixing link counts
+and moving orphans to the ``/lost+found`` directory.
+
+Case Study: Salvaging Directories
+`````````````````````````````````
+
+Unlike extended attributes, directory blocks are all the same size, so
+salvaging directories is straightforward:
+
+1. Find the parent of the directory.
+   If the dotdot entry is not unreadable, try to confirm that the alleged
+   parent has a child entry pointing back to the directory being repaired.
+   Otherwise, walk the filesystem to find it.
+
+2. Walk the first partition of data fork of the directory to find the directory
+   entry data blocks.
+   When one is found,
+
+   a. Walk the directory data block to find candidate entries.
+      When an entry is found:
+
+      i. Check the name for problems, and ignore the name if there are.
+
+      ii. Retrieve the inumber and grab the inode.
+          If that succeeds, add the name, inode number, and file type to the
+          staging xfarray and xblob.
+
+3. If the memory usage of the xfarray and xfblob exceed a certain amount of
+   memory or there are no more directory data blocks to examine, unlock the
+   directory and add the staged dirents into the temporary directory.
+   Truncate the staging files.
+
+4. Use atomic extent swapping to exchange the new and old directory structures.
+   The old directory blocks are now attached to the temporary file.
+
+5. Reap the temporary file.
+
+**Future Work Question**: Should repair revalidate the dentry cache when
+rebuilding a directory?
+
+*Answer*: Yes, it should.
+
+In theory it is necessary to scan all dentry cache entries for a directory to
+ensure that one of the following apply:
+
+1. The cached dentry reflects an ondisk dirent in the new directory.
+
+2. The cached dentry no longer has a corresponding ondisk dirent in the new
+   directory and the dentry can be purged from the cache.

+Parent Pointers
+```````````````
+
+A parent pointer is a piece of file metadata that enables a user to locate the
+file's parent directory without having to traverse the directory tree from the
+root.
+Without them, reconstruction of directory trees is hindered in much the same
+way that the historic lack of reverse space mapping information once hindered
+reconstruction of filesystem space metadata.
+The parent pointer feature, however, makes total directory reconstruction
+possible.
+
+XFS parent pointers include the dirent name and location of the entry within
+the parent directory.
+In other words, child files use extended attributes to store pointers to
+parents in the form ``(parent_inum, parent_gen, dirent_pos) → (dirent_name)``.
+The directory checking process can be strengthened to ensure that the target of
+each dirent also contains a parent pointer pointing back to the dirent.
+Likewise, each parent pointer can be checked by ensuring that the target of
+each parent pointer is a directory and that it contains a dirent matching
+the parent pointer.
+Both online and offline repair can use this strategy.
+
+**Note**: The ondisk format of parent pointers is not yet finalized.

++--------------------------------------------------------------------------+
+| Directory parent pointers were first proposed as an XFS feature more     |
+| than a decade ago by SGI.                                                |
+| Each link from a parent directory to a child file is mirrored with an    |
+| extended attribute in the child that could be used to identify the       |
+| parent directory.                                                        |
+| Unfortunately, this early implementation had major shortcomings and was  |
+| never merged into Linux XFS:                                             |
+|                                                                          |
+| 1. The XFS codebase of the late 2000s did not have the infrastructure to |
+|    enforce strong referential integrity in the directory tree.           |
+|    It did not guarantee that a change in a forward link would always be  |
+|    followed up with the corresponding change to the reverse links.       |
+|                                                                          |
+| 2. Referential integrity was not integrated into offline repair.         |
+|    Checking and repairs were performed on mounted filesystems without    |
+|    taking any kernel or inode locks to coordinate access.                |
+|    It is not clear how this actually worked properly.                    |
+|                                                                          |
+| 3. The extended attribute did not record the name of the directory entry |
+|    in the parent, so the SGI parent pointer implementation cannot be     |
+|    used to reconnect the directory tree.                                 |
+|                                                                          |
+| 4. Extended attribute forks only support 65,536 extents, which means     |
+|    that parent pointer attribute creation is likely to fail at some      |
+|    point before the maximum file link count is achieved.                 |
+|                                                                          |
+| The original parent pointer design was too unstable for something like   |
+| a file system repair to depend on.                                       |
+| Allison Henderson, Chandan Babu, and Catherine Hoang are working on a    |
+| second implementation that solves all shortcomings of the first.         |
+| During 2022, Allison introduced log intent items to track physical       |
+| manipulations of the extended attribute structures.                      |
+| This solves the referential integrity problem by making it possible to   |
+| commit a dirent update and a parent pointer update in the same           |
+| transaction.                                                             |
+| Chandan increased the maximum extent counts of both data and attribute   |
+| forks, thereby ensuring that the extended attribute structure can grow   |
+| to handle the maximum hardlink count of any file.                        |

+Case Study: Repairing Directories with Parent Pointers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Directory rebuilding uses a :ref:`coordinated inode scan <iscan>` and
+a :ref:`directory entry live update hook <liveupdate>` as follows:
+
+1. Set up a temporary directory for generating the new directory structure,
+   an xfblob for storing entry names, and an xfarray for stashing directory
+   updates.
+
+2. Set up an inode scanner and hook into the directory entry code to receive
+   updates on directory operations.
+
+3. For each parent pointer found in each file scanned, decide if the parent
+   pointer references the directory of interest.
+   If so:
+
+   a. Stash an addname entry for this dirent in the xfarray for later.
+
+   b. When finished scanning that file, flush the stashed updates to the
+      temporary directory.
+
+4. For each live directory update received via the hook, decide if the child
+   has already been scanned.
+   If so:
+
+   a. Stash an addname or removename entry for this dirent update in the
+      xfarray for later.
+      We cannot write directly to the temporary directory because hook
+      functions are not allowed to modify filesystem metadata.
+      Instead, we stash updates in the xfarray and rely on the scanner thread
+      to apply the stashed updates to the temporary directory.
+
+5. When the scan is complete, atomically swap the contents of the temporary
+   directory and the directory being repaired.
+   The temporary directory now contains the damaged directory structure.
+
+6. Reap the temporary directory.
+
+7. Update the dirent position field of parent pointers as necessary.
+   This may require the queuing of a substantial number of xattr log intent
+   items.
+
+The proposed patchset is the
+`parent pointers directory repair
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=pptrs-online-dir-repair>`_
+series.
+
+**Unresolved Question**: How will repair ensure that the ``dirent_pos`` fields
+match in the reconstructed directory?
+
+*Answer*: There are a few ways to solve this problem:
+
+1. The field could be designated advisory, since the other three values are
+   sufficient to find the entry in the parent.
+   However, this makes indexed key lookup impossible while repairs are ongoing.
+
+2. We could allow creating directory entries at specified offsets, which solves
+   the referential integrity problem but runs the risk that dirent creation
+   will fail due to conflicts with the free space in the directory.
+
+   These conflicts could be resolved by appending the directory entry and
+   amending the xattr code to support updating an xattr key and reindexing the
+   dabtree, though this would have to be performed with the parent directory
+   still locked.
+
+3. Same as above, but remove the old parent pointer entry and add a new one
+   atomically.
+
+4. Change the ondisk xattr format to ``(parent_inum, name) → (parent_gen)``,
+   which would provide the attr name uniqueness that we require, without
+   forcing repair code to update the dirent position.
+   Unfortunately, this requires changes to the xattr code to support attr
+   names as long as 263 bytes.
+
+5. Change the ondisk xattr format to ``(parent_inum, hash(name)) →
+   (name, parent_gen)``.
+   If the hash is sufficiently resistant to collisions (e.g. sha256) then
+   this should provide the attr name uniqueness that we require.
+   Names shorter than 247 bytes could be stored directly.
+
+Discussion is ongoing under the `parent pointers patch deluge
+<https://www.spinics.net/lists/linux-xfs/msg69397.html>`_.
+
+Case Study: Repairing Parent Pointers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Online reconstruction of a file's parent pointer information works similarly to
+directory reconstruction:
+
+1. Set up a temporary file for generating a new extended attribute structure,
+   an `xfblob<xfblob>` for storing parent pointer names, and an xfarray for
+   stashing parent pointer updates.
+
+2. Set up an inode scanner and hook into the directory entry code to receive
+   updates on directory operations.
+
+3. For each directory entry found in each directory scanned, decide if the
+   dirent references the file of interest.
+   If so:
+
+   a. Stash an addpptr entry for this parent pointer in the xfblob and xfarray
+      for later.
+
+   b. When finished scanning the directory, flush the stashed updates to the
+      temporary directory.
+
+4. For each live directory update received via the hook, decide if the parent
+   has already been scanned.
+   If so:
+
+   a. Stash an addpptr or removepptr entry for this dirent update in the
+      xfarray for later.
+      We cannot write parent pointers directly to the temporary file because
+      hook functions are not allowed to modify filesystem metadata.
+      Instead, we stash updates in the xfarray and rely on the scanner thread
+      to apply the stashed parent pointer updates to the temporary file.
+
+5. Copy all non-parent pointer extended attributes to the temporary file.
+
+6. When the scan is complete, atomically swap the attribute fork of the
+   temporary file and the file being repaired.
+   The temporary file now contains the damaged extended attribute structure.
+
+7. Reap the temporary file.
+
+The proposed patchset is the

+series.
+
+Digression: Offline Checking of Parent Pointers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Examining parent pointers in offline repair works differently because corrupt
+files are erased long before directory tree connectivity checks are performed.
+Parent pointer checks are therefore a second pass to be added to the existing
+connectivity checks:
+
+1. After the set of surviving files has been established (i.e. phase 6),
+   walk the surviving directories of each AG in the filesystem.
+   This is already performed as part of the connectivity checks.
+
+2. For each directory entry found, record the name in an xfblob, and store
+   ``(child_ag_inum, parent_inum, parent_gen, dirent_pos)`` tuples in a
+   per-AG in-memory slab.
+
+3. For each AG in the filesystem,
+
+   a. Sort the per-AG tuples in order of child_ag_inum, parent_inum, and
+      dirent_pos.
+
+   b. For each inode in the AG,
+
+      1. Scan the inode for parent pointers.
+         Record the names in a per-file xfblob, and store ``(parent_inum,
+         parent_gen, dirent_pos)`` tuples in a per-file slab.
+
+      2. Sort the per-file tuples in order of parent_inum, and dirent_pos.
+
+      3. Position one slab cursor at the start of the inode's records in the
+         per-AG tuple slab.
+         This should be trivial since the per-AG tuples are in child inumber
+         order.
+
+      4. Position a second slab cursor at the start of the per-file tuple slab.
+
+      5. Iterate the two cursors in lockstep, comparing the parent_ino and
+         dirent_pos fields of the records under each cursor.
+
+         a. Tuples in the per-AG list but not the per-file list are missing and
+            need to be written to the inode.
+
+         b. Tuples in the per-file list but not the per-AG list are dangling
+            and need to be removed from the inode.
+
+         c. For tuples in both lists, update the parent_gen and name components
+            of the parent pointer if necessary.
+
+4. Move on to examining link counts, as we do today.
+
+The proposed patchset is the
+`offline parent pointers repair
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=pptrs-repair>`_
+series.
+
+Rebuilding directories from parent pointers in offline repair is very
+challenging because it currently uses a single-pass scan of the filesystem
+during phase 3 to decide which files are corrupt enough to be zapped.
+This scan would have to be converted into a multi-pass scan:
+
+1. The first pass of the scan zaps corrupt inodes, forks, and attributes
+   much as it does now.
+   Corrupt directories are noted but not zapped.
+
+2. The next pass records parent pointers pointing to the directories noted
+   as being corrupt in the first pass.
+   This second pass may have to happen after the phase 4 scan for duplicate
+   blocks, if phase 4 is also capable of zapping directories.
+
+3. The third pass resets corrupt directories to an empty shortform directory.
+   Free space metadata has not been ensured yet, so repair cannot yet use the
+   directory building code in libxfs.
+
+4. At the start of phase 6, space metadata have been rebuilt.
+   Use the parent pointer information recorded during step 2 to reconstruct
+   the dirents and add them to the now-empty directories.
+
+This code has not yet been constructed.
+
+.. _orphanage:
+
+The Orphanage
+-------------
+
+Filesystems present files as a directed, and hopefully acyclic, graph.
+In other words, a tree.
+The root of the filesystem is a directory, and each entry in a directory points
+downwards either to more subdirectories or to non-directory files.
+Unfortunately, a disruption in the directory graph pointers result in a
+disconnected graph, which makes files impossible to access via regular path
+resolution.
+
+Without parent pointers, the directory parent pointer online scrub code can
+detect a dotdot entry pointing to a parent directory that doesn't have a link
+back to the child directory and the file link count checker can detect a file
+that isn't pointed to by any directory in the filesystem.
+If such a file has a positive link count, the file is an orphan.
+
+With parent pointers, directories can be rebuilt by scanning parent pointers
+and parent pointers can be rebuilt by scanning directories.
+This should reduce the incidence of files ending up in ``/lost+found``.
+
+When orphans are found, they should be reconnected to the directory tree.
+Offline fsck solves the problem by creating a directory ``/lost+found`` to
+serve as an orphanage, and linking orphan files into the orphanage by using the
+inumber as the name.
+Reparenting a file to the orphanage does not reset any of its permissions or
+ACLs.
+
+This process is more involved in the kernel than it is in userspace.
+The directory and file link count repair setup functions must use the regular
+VFS mechanisms to create the orphanage directory with all the necessary
+security attributes and dentry cache entries, just like a regular directory
+tree modification.
+
+Orphaned files are adopted by the orphanage as follows:
+
+1. Call ``xrep_orphanage_try_create`` at the start of the scrub setup function
+   to try to ensure that the lost and found directory actually exists.
+   This also attaches the orphanage directory to the scrub context.
+
+2. If the decision is made to reconnect a file, take the IOLOCK of both the
+   orphanage and the file being reattached.
+   The ``xrep_orphanage_iolock_two`` function follows the inode locking
+   strategy discussed earlier.
+
+3. Call ``xrep_orphanage_compute_blkres`` and ``xrep_orphanage_compute_name``
+   to compute the new name in the orphanage and the block reservation required.
+
+4. Use ``xrep_orphanage_adoption_prep`` to reserve resources to the repair
+   transaction.
+
+5. Call ``xrep_orphanage_adopt`` to reparent the orphaned file into the lost
+   and found, and update the kernel dentry cache.
+
+The proposed patches are in the
+`orphanage adoption

+
+6. Userspace Algorithms and Data Structures
+===========================================
+
+This section discusses the key algorithms and data structures of the userspace
+program, ``xfs_scrub``, that provide the ability to drive metadata checks and
+repairs in the kernel, verify file data, and look for other potential problems.
+
+.. _scrubcheck:
+
+Checking Metadata
+-----------------
+
+Recall the :ref:`phases of fsck work<scrubphases>` outlined earlier.
+That structure follows naturally from the data dependencies designed into the
+filesystem from its beginnings in 1993.
+In XFS, there are several groups of metadata dependencies:
+
+a. Filesystem summary counts depend on consistency within the inode indices,
+   the allocation group space btrees, and the realtime volume space
+   information.
+
+b. Quota resource counts depend on consistency within the quota file data
+   forks, inode indices, inode records, and the forks of every file on the
+   system.
+
+c. The naming hierarchy depends on consistency within the directory and
+   extended attribute structures.
+   This includes file link counts.
+
+d. Directories, extended attributes, and file data depend on consistency within
+   the file forks that map directory and extended attribute data to physical
+   storage media.
+
+e. The file forks depends on consistency within inode records and the space
+   metadata indices of the allocation groups and the realtime volume.
+   This includes quota and realtime metadata files.
+
+f. Inode records depends on consistency within the inode metadata indices.
+
+g. Realtime space metadata depend on the inode records and data forks of the
+   realtime metadata inodes.
+
+h. The allocation group metadata indices (free space, inodes, reference count,
+   and reverse mapping btrees) depend on consistency within the AG headers and
+   between all the AG metadata btrees.
+
+i. ``xfs_scrub`` depends on the filesystem being mounted and kernel support
+   for online fsck functionality.
+
+Therefore, a metadata dependency graph is a convenient way to schedule checking
+operations in the ``xfs_scrub`` program:
+
+- Phase 1 checks that the provided path maps to an XFS filesystem and detect
+  the kernel's scrubbing abilities, which validates group (i).
+
+- Phase 2 scrubs groups (g) and (h) in parallel using a threaded workqueue.
+
+- Phase 3 scans inodes in parallel.
+  For each inode, groups (f), (e), and (d) are checked, in that order.
+
+- Phase 4 repairs everything in groups (i) through (d) so that phases 5 and 6
+  may run reliably.
+
+- Phase 5 starts by checking groups (b) and (c) in parallel before moving on
+  to checking names.
+
+- Phase 6 depends on groups (i) through (b) to find file data blocks to verify,
+  to read them, and to report which blocks of which files are affected.
+
+- Phase 7 checks group (a), having validated everything else.
+
+Notice that the data dependencies between groups are enforced by the structure
+of the program flow.
+
+Parallel Inode Scans
+--------------------
+
+An XFS filesystem can easily contain hundreds of millions of inodes.
+Given that XFS targets installations with large high-performance storage,
+it is desirable to scrub inodes in parallel to minimize runtime, particularly
+if the program has been invoked manually from a command line.
+This requires careful scheduling to keep the threads as evenly loaded as
+possible.
+
+Early iterations of the ``xfs_scrub`` inode scanner naïvely created a single
+workqueue and scheduled a single workqueue item per AG.
+Each workqueue item walked the inode btree (with ``XFS_IOC_INUMBERS``) to find
+inode chunks and then called bulkstat (``XFS_IOC_BULKSTAT``) to gather enough
+information to construct file handles.
+The file handle was then passed to a function to generate scrub items for each
+metadata object of each inode.
+This simple algorithm leads to thread balancing problems in phase 3 if the
+filesystem contains one AG with a few large sparse files and the rest of the
+AGs contain many smaller files.
+The inode scan dispatch function was not sufficiently granular; it should have
+been dispatching at the level of individual inodes, or, to constrain memory
+consumption, inode btree records.
+
+Thanks to Dave Chinner, bounded workqueues in userspace enable ``xfs_scrub`` to
+avoid this problem with ease by adding a second workqueue.
+Just like before, the first workqueue is seeded with one workqueue item per AG,
+and it uses INUMBERS to find inode btree chunks.
+The second workqueue, however, is configured with an upper bound on the number
+of items that can be waiting to be run.
+Each inode btree chunk found by the first workqueue's workers are queued to the
+second workqueue, and it is this second workqueue that queries BULKSTAT,
+creates a file handle, and passes it to a function to generate scrub items for
+each metadata object of each inode.
+If the second workqueue is too full, the workqueue add function blocks the
+first workqueue's workers until the backlog eases.
+This doesn't completely solve the balancing problem, but reduces it enough to
+move on to more pressing issues.
+
+The proposed patchsets are the scrub
+`performance tweaks
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=scrub-performance-tweaks>`_
+and the
+`inode scan rebalance
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=scrub-iscan-rebalance>`_
+series.
+
+.. _scrubrepair:
+
+Scheduling Repairs
+------------------
+
+During phase 2, corruptions and inconsistencies reported in any AGI header or
+inode btree are repaired immediately, because phase 3 relies on proper
+functioning of the inode indices to find inodes to scan.
+Failed repairs are rescheduled to phase 4.
+Problems reported in any other space metadata are deferred to phase 4.
+Optimization opportunities are always deferred to phase 4, no matter their
+origin.
+
+During phase 3, corruptions and inconsistencies reported in any part of a
+file's metadata are repaired immediately if all space metadata were validated
+during phase 2.
+Repairs that fail or cannot be repaired immediately are scheduled for phase 4.
+
+In the original design of ``xfs_scrub``, it was thought that repairs would be
+so infrequent that the ``struct xfs_scrub_metadata`` objects used to
+communicate with the kernel could also be used as the primary object to
+schedule repairs.
+With recent increases in the number of optimizations possible for a given
+filesystem object, it became much more memory-efficient to track all eligible
+repairs for a given filesystem object with a single repair item.
+Each repair item represents a single lockable object -- AGs, metadata files,
+individual inodes, or a class of summary information.
+
+Phase 4 is responsible for scheduling a lot of repair work in as quick a
+manner as is practical.
+The :ref:`data dependencies <scrubcheck>` outlined earlier still apply, which
+means that ``xfs_scrub`` must try to complete the repair work scheduled by
+phase 2 before trying repair work scheduled by phase 3.
+The repair process is as follows:
+
+1. Start a round of repair with a workqueue and enough workers to keep the CPUs
+   as busy as the user desires.
+
+   a. For each repair item queued by phase 2,
+
+      i.   Ask the kernel to repair everything listed in the repair item for a
+           given filesystem object.
+
+      ii.  Make a note if the kernel made any progress in reducing the number
+           of repairs needed for this object.
+
+      iii. If the object no longer requires repairs, revalidate all metadata
+           associated with this object.
+           If the revalidation succeeds, drop the repair item.
+           If not, requeue the item for more repairs.
+
+   b. If any repairs were made, jump back to 1a to retry all the phase 2 items.
+
+   c. For each repair item queued by phase 3,
+
+      i.   Ask the kernel to repair everything listed in the repair item for a
+           given filesystem object.
+
+      ii.  Make a note if the kernel made any progress in reducing the number
+           of repairs needed for this object.
+
+      iii. If the object no longer requires repairs, revalidate all metadata
+           associated with this object.
+           If the revalidation succeeds, drop the repair item.
+           If not, requeue the item for more repairs.
+
+   d. If any repairs were made, jump back to 1c to retry all the phase 3 items.
+
+2. If step 1 made any repair progress of any kind, jump back to step 1 to start
+   another round of repair.
+
+3. If there are items left to repair, run them all serially one more time.
+   Complain if the repairs were not successful, since this is the last chance
+   to repair anything.
+
+Corruptions and inconsistencies encountered during phases 5 and 7 are repaired
+immediately.
+Corrupt file data blocks reported by phase 6 cannot be recovered by the
+filesystem.

+
+Checking Names for Confusable Unicode Sequences
+-----------------------------------------------
+
+If ``xfs_scrub`` succeeds in validating the filesystem metadata by the end of
+phase 4, it moves on to phase 5, which checks for suspicious looking names in
+the filesystem.
+These names consist of the filesystem label, names in directory entries, and
+the names of extended attributes.
+Like most Unix filesystems, XFS imposes the sparest of constraints on the
+contents of a name:
+
+- Slashes and null bytes are not allowed in directory entries.
+
+- Null bytes are not allowed in userspace-visible extended attributes.
+
+- Null bytes are not allowed in the filesystem label.
+
+Directory entries and attribute keys store the length of the name explicitly
+ondisk, which means that nulls are not name terminators.
+For this section, the term "naming domain" refers to any place where names are
+presented together -- all the names in a directory, or all the attributes of a
+file.
+
+Although the Unix naming constraints are very permissive, the reality of most
+modern-day Linux systems is that programs work with Unicode character code
+points to support international languages.
+These programs typically encode those code points in UTF-8 when interfacing
+with the C library because the kernel expects null-terminated names.
+In the common case, therefore, names found in an XFS filesystem are actually
+UTF-8 encoded Unicode data.
+
+To maximize its expressiveness, the Unicode standard defines separate control
+points for various characters that render similarly or identically in writing
+systems around the world.
+For example, the character "Cyrillic Small Letter A" U+0430 "а" often renders
+identically to "Latin Small Letter A" U+0061 "a".
+
+The standard also permits characters to be constructed in multiple ways --
+either by using a defined code point, or by combining one code point with
+various combining marks.
+For example, the character "Angstrom Sign U+212B "Å" can also be expressed
+as "Latin Capital Letter A" U+0041 "A" followed by "Combining Ring Above"
+U+030A "◌̊".
+Both sequences render identically.
+
+Like the standards that preceded it, Unicode also defines various control
+characters to alter the presentation of text.
+For example, the character "Right-to-Left Override" U+202E can trick some
+programs into rendering "moo\\xe2\\x80\\xaegnp.txt" as "mootxt.png".
+A second category of rendering problems involves whitespace characters.
+If the character "Zero Width Space" U+200B is encountered in a file name, the
+name will render identically to a name that does not have the zero width
+space.
+
+If two names within a naming domain have different byte sequences but render
+identically, a user may be confused by it.
+The kernel, in its indifference to upper level encoding schemes, permits this.
+Most filesystem drivers persist the byte sequence names that are given to them
+by the VFS.
+
+Techniques for detecting confusable names are explained in great detail in
+sections 4 and 5 of the
+`Unicode Security Mechanisms <https://unicode.org/reports/tr39/>`_
+document.
+When ``xfs_scrub`` detects UTF-8 encoding in use on a system, it uses the
+Unicode normalization form NFD in conjunction with the confusable name
+detection component of
+`libicu <https://github.com/unicode-org/icu>`_
+to identify names with a directory or within a file's extended attributes that
+could be confused for each other.
+Names are also checked for control characters, non-rendering characters, and
+mixing of bidirectional characters.
+All of these potential issues are reported to the system administrator during
+phase 5.
+
+Media Verification of File Data Extents
+---------------------------------------
+
+The system administrator can elect to initiate a media scan of all file data
+blocks.
+This scan after validation of all filesystem metadata (except for the summary
+counters) as phase 6.
+The scan starts by calling ``FS_IOC_GETFSMAP`` to scan the filesystem space map
+to find areas that are allocated to file data fork extents.
+Gaps betweeen data fork extents that are smaller than 64k are treated as if
+they were data fork extents to reduce the command setup overhead.
+When the space map scan accumulates a region larger than 32MB, a media
+verification request is sent to the disk as a directio read of the raw block
+device.
+
+If the verification read fails, ``xfs_scrub`` retries with single-block reads
+to narrow down the failure to the specific region of the media and recorded.
+When it has finished issuing verification requests, it again uses the space
+mapping ioctl to map the recorded media errors back to metadata structures
+and report what has been lost.
+For media errors in blocks owned by files, parent pointers can be used to
+construct file paths from inode numbers for user-friendly reporting.
+
+7. Conclusion and Future Work
+=============================
+
+It is hoped that the reader of this document has followed the designs laid out
+in this document and now has some familiarity with how XFS performs online
+rebuilding of its metadata indices, and how filesystem users can interact with
+that functionality.
+Although the scope of this work is daunting, it is hoped that this guide will
+make it easier for code readers to understand what has been built, for whom it
+has been built, and why.
+Please feel free to contact the XFS mailing list with questions.
+
+FIEXCHANGE_RANGE
+----------------
+
+As discussed earlier, a second frontend to the atomic extent swap mechanism is
+a new ioctl call that userspace programs can use to commit updates to files
+atomically.
+This frontend has been out for review for several years now, though the
+necessary refinements to online repair and lack of customer demand mean that
+the proposal has not been pushed very hard.
+
+Extent Swapping with Regular User Files
+```````````````````````````````````````
+
+As mentioned earlier, XFS has long had the ability to swap extents between
+files, which is used almost exclusively by ``xfs_fsr`` to defragment files.
+The earliest form of this was the fork swap mechanism, where the entire
+contents of data forks could be exchanged between two files by exchanging the
+raw bytes in each inode fork's immediate area.
+When XFS v5 came along with self-describing metadata, this old mechanism grew
+some log support to continue rewriting the owner fields of BMBT blocks during
+log recovery.
+When the reverse mapping btree was later added to XFS, the only way to maintain
+the consistency of the fork mappings with the reverse mapping index was to
+develop an iterative mechanism that used deferred bmap and rmap operations to
+swap mappings one at a time.
+This mechanism is identical to steps 2-3 from the procedure above except for
+the new tracking items, because the atomic extent swap mechanism is an
+iteration of an existing mechanism and not something totally novel.
+For the narrow case of file defragmentation, the file contents must be
+identical, so the recovery guarantees are not much of a gain.
+
+Atomic extent swapping is much more flexible than the existing swapext
+implementations because it can guarantee that the caller never sees a mix of
+old and new contents even after a crash, and it can operate on two arbitrary
+file fork ranges.
+The extra flexibility enables several new use cases:
+
+- **Atomic commit of file writes**: A userspace process opens a file that it
+  wants to update.
+  Next, it opens a temporary file and calls the file clone operation to reflink
+  the first file's contents into the temporary file.
+  Writes to the original file should instead be written to the temporary file.
+  Finally, the process calls the atomic extent swap system call
+  (``FIEXCHANGE_RANGE``) to exchange the file contents, thereby committing all
+  of the updates to the original file, or none of them.
+
+.. _swapext_if_unchanged:
+
+- **Transactional file updates**: The same mechanism as above, but the caller
+  only wants the commit to occur if the original file's contents have not
+  changed.
+  To make this happen, the calling process snapshots the file modification and
+  change timestamps of the original file before reflinking its data to the
+  temporary file.
+  When the program is ready to commit the changes, it passes the timestamps
+  into the kernel as arguments to the atomic extent swap system call.
+  The kernel only commits the changes if the provided timestamps match the
+  original file.
+
+- **Emulation of atomic block device writes**: Export a block device with a
+  logical sector size matching the filesystem block size to force all writes
+  to be aligned to the filesystem block size.
+  Stage all writes to a temporary file, and when that is complete, call the
+  atomic extent swap system call with a flag to indicate that holes in the
+  temporary file should be ignored.
+  This emulates an atomic device write in software, and can support arbitrary
+  scattered writes.
+
+Vectorized Scrub
+----------------
+
+As it turns out, the :ref:`refactoring <scrubrepair>` of repair items mentioned
+earlier was a catalyst for enabling a vectorized scrub system call.
+Since 2018, the cost of making a kernel call has increased considerably on some
+systems to mitigate the effects of speculative execution attacks.
+This incentivizes program authors to make as few system calls as possible to
+reduce the number of times an execution path crosses a security boundary.
+
+With vectorized scrub, userspace pushes to the kernel the identity of a
+filesystem object, a list of scrub types to run against that object, and a
+simple representation of the data dependencies between the selected scrub
+types.
+The kernel executes as much of the caller's plan as it can until it hits a
+dependency that cannot be satisfied due to a corruption, and tells userspace
+how much was accomplished.
+It is hoped that ``io_uring`` will pick up enough of this functionality that
+online fsck can use that instead of adding a separate vectored scrub system
+call to XFS.
+
+The relevant patchsets are the
+`kernel vectorized scrub
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=vectorized-scrub>`_
+and
+`userspace vectorized scrub
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=vectorized-scrub>`_
+series.
+
+Quality of Service Targets for Scrub
+------------------------------------
+
+One serious shortcoming of the online fsck code is that the amount of time that
+it can spend in the kernel holding resource locks is basically unbounded.
+Userspace is allowed to send a fatal signal to the process which will cause
+``xfs_scrub`` to exit when it reaches a good stopping point, but there's no way
+for userspace to provide a time budget to the kernel.
+Given that the scrub codebase has helpers to detect fatal signals, it shouldn't
+be too much work to allow userspace to specify a timeout for a scrub/repair
+operation and abort the operation if it exceeds budget.
+However, most repair functions have the property that once they begin to touch
+ondisk metadata, the operation cannot be cancelled cleanly, after which a QoS
+timeout is no longer useful.
+
+Defragmenting Free Space
+------------------------
+
+Over the years, many XFS users have requested the creation of a program to
+clear a portion of the physical storage underlying a filesystem so that it
+becomes a contiguous chunk of free space.
+Call this free space defragmenter ``clearspace`` for short.
+
+The first piece the ``clearspace`` program needs is the ability to read the
+reverse mapping index from userspace.
+This already exists in the form of the ``FS_IOC_GETFSMAP`` ioctl.
+The second piece it needs is a new fallocate mode
+(``FALLOC_FL_MAP_FREE_SPACE``) that allocates the free space in a region and
+maps it to a file.
+Call this file the "space collector" file.
+The third piece is the ability to force an online repair.
+
+To clear all the metadata out of a portion of physical storage, clearspace
+uses the new fallocate map-freespace call to map any free space in that region
+to the space collector file.
+Next, clearspace finds all metadata blocks in that region by way of
+``GETFSMAP`` and issues forced repair requests on the data structure.
+This often results in the metadata being rebuilt somewhere that is not being
+cleared.
+After each relocation, clearspace calls the "map free space" function again to
+collect any newly freed space in the region being cleared.
+
+To clear all the file data out of a portion of the physical storage, clearspace
+uses the FSMAP information to find relevant file data blocks.
+Having identified a good target, it uses the ``FICLONERANGE`` call on that part
+of the file to try to share the physical space with a dummy file.
+Cloning the extent means that the original owners cannot overwrite the
+contents; any changes will be written somewhere else via copy-on-write.
+Clearspace makes its own copy of the frozen extent in an area that is not being
+cleared, and uses ``FIEDEUPRANGE`` (or the :ref:`atomic extent swap
+<swapext_if_unchanged>` feature) to change the target file's data extent
+mapping away from the area being cleared.
+When all other mappings have been moved, clearspace reflinks the space into the
+space collector file so that it becomes unavailable.
+
+There are further optimizations that could apply to the above algorithm.
+To clear a piece of physical storage that has a high sharing factor, it is
+strongly desirable to retain this sharing factor.
+In fact, these extents should be moved first to maximize sharing factor after
+the operation completes.
+To make this work smoothly, clearspace needs a new ioctl
+(``FS_IOC_GETREFCOUNTS``) to report reference count information to userspace.
+With the refcount information exposed, clearspace can quickly find the longest,
+most shared data extents in the filesystem, and target them first.
+
+**Future Work Question**: How might the filesystem move inode chunks?
+
+*Answer*: To move inode chunks, Dave Chinner constructed a prototype program
+that creates a new file with the old contents and then locklessly runs around
+the filesystem updating directory entries.
+The operation cannot complete if the filesystem goes down.
+That problem isn't totally insurmountable: create an inode remapping table
+hidden behind a jump label, and a log item that tracks the kernel walking the
+filesystem to update directory entries.
+The trouble is, the kernel can't do anything about open files, since it cannot
+revoke them.
+
+**Future Work Question**: Can static keys be used to minimize the cost of
+supporting ``revoke()`` on XFS files?
+
+*Answer*: Yes.
+Until the first revocation, the bailout code need not be in the call path at
+all.
+
+The relevant patchsets are the
+`kernel freespace defrag
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=defrag-freespace>`_
+and
+`userspace freespace defrag
+<https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=defrag-freespace>`_
+series.
+
+Shrinking Filesystems
+---------------------
+
+Removing the end of the filesystem ought to be a simple matter of evacuating
+the data and metadata at the end of the filesystem, and handing the freed space
+to the shrink code.
+That requires an evacuation of the space at end of the filesystem, which is a
+use of free space defragmentation!

+False Sharing
+=============
+
+What is False Sharing
+=====================
+False sharing is related with cache mechanism of maintaining the data
+coherence of one cache line stored in multiple CPU's caches; then
+academic definition for it is in [1]_. Consider a struct with a
+refcount and a string::
+
+	struct foo {
+		refcount_t refcount;
+		...
+		char name[16];
+	} ____cacheline_internodealigned_in_smp;
+
+Member 'refcount'(A) and 'name'(B) _share_ one cache line like below::
+
+                +-----------+                     +-----------+
+                |   CPU 0   |                     |   CPU 1   |

+
+'refcount' is modified frequently, but 'name' is set once at object
+creation time and is never modified.  When many CPUs access 'foo' at
+the same time, with 'refcount' being only bumped by one CPU frequently
+and 'name' being read by other CPUs, all those reading CPUs have to
+reload the whole cache line over and over due to the 'sharing', even
+though 'name' is never changed.
+
+There are many real-world cases of performance regressions caused by
+false sharing.  One of these is a rw_semaphore 'mmap_lock' inside
+mm_struct struct, whose cache line layout change triggered a
+regression and Linus analyzed in [2]_.
+
+There are two key factors for a harmful false sharing:
+
+* A global datum accessed (shared) by many CPUs
+* In the concurrent accesses to the data, there is at least one write
+  operation: write/write or write/read cases.
+
+The sharing could be from totally unrelated kernel components, or
+different code paths of the same kernel component.
+
+
+False Sharing Pitfalls
+======================
+Back in time when one platform had only one or a few CPUs, hot data
+members could be purposely put in the same cache line to make them
+cache hot and save cacheline/TLB, like a lock and the data protected
+by it.  But for recent large system with hundreds of CPUs, this may
+not work when the lock is heavily contended, as the lock owner CPU
+could write to the data, while other CPUs are busy spinning the lock.
+
+Looking at past cases, there are several frequently occurring patterns
+for false sharing:
+
+* lock (spinlock/mutex/semaphore) and data protected by it are
+  purposely put in one cache line.
+* global data being put together in one cache line. Some kernel
+  subsystems have many global parameters of small size (4 bytes),
+  which can easily be grouped together and put into one cache line.
+* data members of a big data structure randomly sitting together
+  without being noticed (cache line is usually 64 bytes or more),
+  like 'mem_cgroup' struct.
+
+Following 'mitigation' section provides real-world examples.
+
+False sharing could easily happen unless they are intentionally
+checked, and it is valuable to run specific tools for performance
+critical workloads to detect false sharing affecting performance case
+and optimize accordingly.
+
+
+How to detect and analyze False Sharing
+========================================
+perf record/report/stat are widely used for performance tuning, and
+once hotspots are detected, tools like 'perf-c2c' and 'pahole' can
+be further used to detect and pinpoint the possible false sharing
+data structures.  'addr2line' is also good at decoding instruction
+pointer when there are multiple layers of inline functions.
+
+perf-c2c can capture the cache lines with most false sharing hits,
+decoded functions (line number of file) accessing that cache line,
+and in-line offset of the data. Simple commands are::
+
+  $ perf c2c record -ag sleep 3
+  $ perf c2c report --call-graph none -k vmlinux
+
+When running above during testing will-it-scale's tlb_flush1 case,
+perf reports something like::
+
+  Total records                     :    1658231
+  Locked Load/Store Operations      :      89439
+  Load Operations                   :     623219
+  Load Local HITM                   :      92117
+  Load Remote HITM                  :        139

+
+A nice introduction for perf-c2c is [3]_.
+
+'pahole' decodes data structure layouts delimited in cache line
+granularity.  Users can match the offset in perf-c2c output with
+pahole's decoding to locate the exact data members.  For global
+data, users can search the data address in System.map.
+
+
+Possible Mitigations
+====================
+False sharing does not always need to be mitigated.  False sharing
+mitigations should balance performance gains with complexity and
+space consumption.  Sometimes, lower performance is OK, and it's
+unnecessary to hyper-optimize every rarely used data structure or
+a cold data path.
+
+False sharing hurting performance cases are seen more frequently with
+core count increasing.  Because of these detrimental effects, many
+patches have been proposed across variety of subsystems (like
+networking and memory management) and merged.  Some common mitigations
+(with examples) are:
+
+* Separate hot global data in its own dedicated cache line, even if it
+  is just a 'short' type. The downside is more consumption of memory,
+  cache line and TLB entries.
+
+  - Commit 91b6d3256356 ("net: cache align tcp_memory_allocated, tcp_sockets_allocated")
+
+* Reorganize the data structure, separate the interfering members to
+  different cache lines.  One downside is it may introduce new false
+  sharing of other members.
+
+  - Commit 802f1d522d5f ("mm: page_counter: re-layout structure to reduce false sharing")
+
+* Replace 'write' with 'read' when possible, especially in loops.
+  Like for some global variable, use compare(read)-then-write instead
+  of unconditional write. For example, use::
+
+	if (!test_bit(XXX))
+		set_bit(XXX);
+
+  instead of directly "set_bit(XXX);", similarly for atomic_t data::
+
+	if (atomic_read(XXX) == AAA)
+		atomic_set(XXX, BBB);
+
+  - Commit 7b1002f7cfe5 ("bcache: fixup bcache_dev_sectors_dirty_add() multithreaded CPU false sharing")
+  - Commit 292648ac5cf1 ("mm: gup: allow FOLL_PIN to scale in SMP")
+
+* Turn hot global data to 'per-cpu data + global data' when possible,
+  or reasonably increase the threshold for syncing per-cpu data to
+  global data, to reduce or postpone the 'write' to that global data.
+
+  - Commit 520f897a3554 ("ext4: use percpu_counters for extent_status cache hits/misses")
+  - Commit 56f3547bfa4d ("mm: adjust vm_committed_as_batch according to vm overcommit policy")
+
+Surely, all mitigations should be carefully verified to not cause side
+effects.  To avoid introducing false sharing when coding, it's better
+to:
+
+* Be aware of cache line boundaries
+* Group mostly read-only fields together
+* Group things that are written at the same time together
+* Separate frequently read and frequently written fields on
+  different cache lines.
+
+and better add a comment stating the false sharing consideration.
+
+One note is, sometimes even after a severe false sharing is detected
+and solved, the performance may still have no obvious improvement as
+the hotspot switches to a new place.
+
+
+Miscellaneous
+=============
+One open issue is that kernel has an optional data structure
+randomization mechanism, which also randomizes the situation of cache
+line sharing of data members.

+=========================================
+
+Description
+-----------
+
+The MT6370 integrates a four-channel RGB LED driver, designed to provide a
+variety of lighting effect for mobile device applications. The RGB LED devices
+includes a smart LED string controller and it can drive 3 channels of LEDs with
+a sink current up to 24mA and a CHG_VIN power good indicator LED with sink
+current up to 6mA. It provides three operation modes for RGB LEDs:
+PWM Dimming mode, breath pattern mode, and constant current mode. The device
+can increase or decrease the brightness of the RGB LED via an I2C interface.
+
+The breath pattern for a channel can be programmed using the "pattern" trigger,
+using the hw_pattern attribute.
+
+/sys/class/leds/<led>/hw_pattern
+--------------------------------
+
+Specify a hardware breath pattern for a MT6370 RGB LED.
+
+The breath pattern is a series of timing pairs, with the hold-time expressed in
+milliseconds. And the brightness is controlled by
+'/sys/class/leds/<led>/brightness'. The pattern doesn't include the brightness
+setting. Hardware pattern only controls the timing for each pattern stage
+depending on the current brightness setting.

+Implementation notes
+====================
+
+We specifically decided not to use VMA information in order to avoid relying on
+MM states (except for limited "struct page" info). The page table check is a
+separate from Linux-MM state machine that verifies that the user accessible
+pages are not falsely shared.
+
+PAGE_TABLE_CHECK depends on EXCLUSIVE_SYSTEM_RAM. The reason is that without
+EXCLUSIVE_SYSTEM_RAM, users are allowed to map arbitrary physical memory
+regions into the userspace via /dev/mem. At the same time, pages may change
+their properties (e.g., from anonymous pages to named pages) while they are
+still being mapped in the userspace, leading to "corruption" detected by the
+page table check.
+
+Even with EXCLUSIVE_SYSTEM_RAM, I/O pages may be still allowed to be mapped via
+/dev/mem. However, these pages are always considered as named pages, so they
+won't break the logic used in the page table check.

+
+Firmware Management
+===================
+
+The ``flash`` command can update a the DSC firmware.  The downloaded firmware
+will be saved into either of firmware bank 1 or bank 2, whichever is not
+currently in use, and that bank will used for the next boot::
+
+  # devlink dev flash pci/0000:b5:00.0 \
+            file pensando/dsc_fw_1.63.0-22.tar
+
+Health Reporters
+================
+
+The driver supports a devlink health reporter for FW status::
+
+  # devlink health show pci/0000:2b:00.0 reporter fw
+  pci/0000:2b:00.0:
+    reporter fw
+      state healthy error 0 recover 0
+  # devlink health diagnose pci/0000:2b:00.0 reporter fw
+   Status: healthy State: 1 Generation: 0 Recoveries: 0
+
+Enabling the driver
+===================
+
+The driver is enabled via the standard kernel configuration system,
+using the make command::
+
+  make oldconfig/menuconfig/etc.
+
+The driver is located in the menu structure at:

-In This Release
-===============
-
-This file describes the ixgb Linux Base Driver for the 10 Gigabit Intel(R)
-Network Connection.  This driver includes support for Itanium(R)2-based
-systems.
-
-For questions related to hardware requirements, refer to the documentation
-supplied with your 10 Gigabit adapter.  All hardware requirements listed apply
-to use with Linux.
-
-The following features are available in this kernel:
- - Native VLANs
- - Channel Bonding (teaming)
- - SNMP
-
-Channel Bonding documentation can be found in the Linux kernel source:
-/Documentation/networking/bonding.rst
-
-The driver information previously displayed in the /proc filesystem is not
-supported in this release.  Alternatively, you can use ethtool (version 1.6
-or later), lspci, and iproute2 to obtain the same information.
-
-Instructions on updating ethtool can be found in the section "Additional
-Configurations" later in this document.
-
-
-Identifying Your Adapter
-========================
-
-The following Intel network adapters are compatible with the drivers in this
-release:
-
-+------------+------------------------------+----------------------------------+
-| Controller | Adapter Name                 | Physical Layer                   |
-+============+==============================+==================================+
-| 82597EX    | Intel(R) PRO/10GbE LR/SR/CX4 | - 10G Base-LR (fiber)            |

-+------------+------------------------------+----------------------------------+
-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
-    https://support.intel.com
-
-
-Command Line Parameters
-=======================
-
-If the driver is built as a module, the  following optional parameters are
-used by entering them on the command line with the modprobe command using
-this syntax::
-
-    modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
-
-For example, with two 10GbE PCI adapters, entering::
-
-    modprobe ixgb TxDescriptors=80,128
-
-loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
-resources for the second adapter.
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-Copybreak
----------
-:Valid Range: 0-XXXX
-:Default Value: 256
-
-    This is the maximum size of packet that is copied to a new buffer on
-    receive.
-
-Debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-    This parameter adjusts the level of debug messages displayed in the
-    system logs.
-
-FlowControl
------------
-:Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
-:Default Value: 1 if no EEPROM, otherwise read from EEPROM
-
-    This parameter controls the automatic generation(Tx) and response(Rx) to
-    Ethernet PAUSE frames.  There are hardware bugs associated with enabling
-    Tx flow control so beware.
-
-RxDescriptors
--------------
-:Valid Range: 64-4096
-:Default Value: 1024
-
-    This value is the number of receive descriptors allocated by the driver.
-    Increasing this value allows the driver to buffer more incoming packets.
-    Each descriptor is 16 bytes.  A receive buffer is also allocated for
-    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
-    depending on the MTU setting.  When the MTU size is 1500 or less, the
-    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
-    receive buffer size will be either 4056, 8192, or 16384 bytes.  The
-    maximum MTU size is 16114.
-
-TxDescriptors
--------------
-:Valid Range: 64-4096
-:Default Value: 256
-
-    This value is the number of transmit descriptors allocated by the driver.
-    Increasing this value allows the driver to queue more transmits.  Each
-    descriptor is 16 bytes.
-
-RxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 72
-
-    This value delays the generation of receive interrupts in units of
-    0.8192 microseconds.  Receive interrupt reduction can improve CPU
-    efficiency if properly tuned for specific network traffic.  Increasing
-    this value adds extra latency to frame reception and can end up
-    decreasing the throughput of TCP traffic.  If the system is reporting
-    dropped receives, this value may be set too high, causing the driver to
-    run out of available receive descriptors.
-
-TxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 32
-
-    This value delays the generation of transmit interrupts in units of
-    0.8192 microseconds.  Transmit interrupt reduction can improve CPU
-    efficiency if properly tuned for specific network traffic.  Increasing
-    this value adds extra latency to frame transmission and can end up
-    decreasing the throughput of TCP traffic.  If this value is set too high,
-    it will cause the driver to run out of available transmit descriptors.
-
-XsumRX
-------
-:Valid Range: 0-1
-:Default Value: 1
-
-    A value of '1' indicates that the driver should enable IP checksum
-    offload for received packets (both UDP and TCP) to the adapter hardware.
-
-RxFCHighThresh
---------------
-:Valid Range: 1,536-262,136 (0x600 - 0x3FFF8, 8 byte granularity)
-:Default Value: 196,608 (0x30000)
-
-    Receive Flow control high threshold (when we send a pause frame)
-
-RxFCLowThresh
--------------
-:Valid Range: 64-262,136 (0x40 - 0x3FFF8, 8 byte granularity)
-:Default Value: 163,840 (0x28000)
-
-    Receive Flow control low threshold (when we send a resume frame)
-
-FCReqTimeout
-------------
-:Valid Range: 1-65535
-:Default Value: 65535
-
-    Flow control request timeout (how long to pause the link partner's tx)
-
-IntDelayEnable
---------------
-:Value Range: 0,1
-:Default Value: 1
-
-    Interrupt Delay, 0 disables transmit interrupt delay and 1 enables it.
-
-
-Improving Performance
-=====================
-
-With the 10 Gigabit server adapters, the default Linux configuration will
-very likely limit the total available throughput artificially.  There is a set
-of configuration changes that, when applied together, will increase the ability
-of Linux to transmit and receive data.  The following enhancements were
-originally acquired from settings published at https://www.spec.org/web99/ for
-various submitted results using Linux.
-
-NOTE:
-  These changes are only suggestions, and serve as a starting point for
-  tuning your network performance.
-
-The changes are made in three major ways, listed in order of greatest effect:
-
-- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
-  parameter.
-- Use sysctl to modify /proc parameters (essentially kernel tuning)
-- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
-  transmit burst lengths on the bus.
-
-NOTE:
-  setpci modifies the adapter's configuration registers to allow it to read
-  up to 4k bytes at a time (for transmits).  However, for some systems the
-  behavior after modifying this register may be undefined (possibly errors of
-  some kind).  A power-cycle, hard reset or explicitly setting the e6 register
-  back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
-  stable configuration.
-
-- COPY these lines and paste them into ixgb_perf.sh:
-
-::
-
-  #!/bin/bash
-  echo "configuring network performance , edit this file to change the interface
-  or device ID of 10GbE card"
-  # set mmrbc to 4k reads, modify only Intel 10GbE device IDs
-  # replace 1a48 with appropriate 10GbE device's ID installed on the system,
-  # if needed.
-  setpci -d 8086:1a48 e6.b=2e
-  # set the MTU (max transmission unit) - it requires your switch and clients
-  # to change as well.
-  # set the txqueuelen
-  # your ixgb adapter should be loaded as eth1 for this to work, change if needed
-  ip li set dev eth1 mtu 9000 txqueuelen 1000 up
-  # call the sysctl utility to modify /proc/sys entries
-  sysctl -p ./sysctl_ixgb.conf
-
-- COPY these lines and paste them into sysctl_ixgb.conf:
-
-::
-
-  # some of the defaults may be different for your kernel
-  # call this file with sysctl -p <this file>
-  # these are just suggested values that worked well to increase throughput in
-  # several network benchmark tests, your mileage may vary
-
-  ### IPV4 specific settings
-  # turn TCP timestamp support off, default 1, reduces CPU use
-  net.ipv4.tcp_timestamps = 0
-  # turn SACK support off, default on
-  # on systems with a VERY fast bus -> memory interface this is the big gainer
-  net.ipv4.tcp_sack = 0
-  # set min/default/max TCP read buffer, default 4096 87380 174760
-  net.ipv4.tcp_rmem = 10000000 10000000 10000000
-  # set min/pressure/max TCP write buffer, default 4096 16384 131072
-  net.ipv4.tcp_wmem = 10000000 10000000 10000000
-  # set min/pressure/max TCP buffer space, default 31744 32256 32768
-  net.ipv4.tcp_mem = 10000000 10000000 10000000
-
-  ### CORE settings (mostly for socket and UDP effect)
-  # set maximum receive socket buffer size, default 131071
-  net.core.rmem_max = 524287
-  # set maximum send socket buffer size, default 131071
-  net.core.wmem_max = 524287
-  # set default receive socket buffer size, default 65535
-  net.core.rmem_default = 524287
-  # set default send socket buffer size, default 65535
-  net.core.wmem_default = 524287
-  # set maximum amount of option memory buffers, default 10240
-  net.core.optmem_max = 524287
-  # set number of unprocessed input packets before kernel starts dropping them; default 300
-  net.core.netdev_max_backlog = 300000
-
-Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
-your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
-ID installed on the system.
-
-NOTE:
-  Unless these scripts are added to the boot process, these changes will
-  only last only until the next system reboot.
-
-
-Resolving Slow UDP Traffic
---------------------------
-If your server does not seem to be able to receive UDP traffic as fast as it
-can receive TCP traffic, it could be because Linux, by default, does not set
-the network stack buffers as large as they need to be to support high UDP
-transfer rates.  One way to alleviate this problem is to allow more memory to
-be used by the IP stack to store incoming data.
-
-For instance, use the commands::
-
-    sysctl -w net.core.rmem_max=262143
-
-and::
-
-    sysctl -w net.core.rmem_default=262143
-
-to increase the read buffer memory max and default to 262143 (256k - 1) from
-defaults of max=131071 (128k - 1) and default=65535 (64k - 1).  These variables
-will increase the amount of memory used by the network stack for receives, and
-can be increased significantly more if necessary for your application.
-
-
-Additional Configurations
-=========================
-
-Configuring the Driver on Different Distributions
--------------------------------------------------
-Configuring a network driver to load properly when the system is started is
-distribution dependent. Typically, the configuration process involves adding
-an alias line to /etc/modprobe.conf as well as editing other system startup
-scripts and/or configuration files.  Many popular Linux distributions ship
-with tools to make these changes for you.  To learn the proper way to
-configure a network device for your system, refer to your distribution
-documentation.  If during this process you are asked for the driver or module
-name, the name for the Linux Base Driver for the Intel 10GbE Family of
-Adapters is ixgb.
-
-Viewing Link Messages
----------------------
-Link messages will not be displayed to the console if the distribution is
-restricting system messages. In order to see network driver link messages on
-your console, set dmesg to eight by entering the following::
-
-    dmesg -n 8
-
-NOTE: This setting is not saved across reboots.
-
-Jumbo Frames
-------------
-The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
-enabled by changing the MTU to a value larger than the default of 1500.
-The maximum value for the MTU is 16114.  Use the ip command to
-increase the MTU size.  For example::
-
-    ip li set dev ethx mtu 9000
-
-The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
-with the maximum Jumbo Frames size of 16128.
-
-Ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information.  The ethtool
-version 1.6 or later is required for this functionality.
-
-The latest release of ethtool can be found from
-https://www.kernel.org/pub/software/network/ethtool/
-
-NOTE:
-  The ethtool version 1.6 only supports a limited set of ethtool options.
-  Support for a more complete ethtool feature set can be enabled by
-  upgrading to the latest version.
-
-NAPI

-NAPI (Rx polling mode) is supported in the ixgb driver.
-
-See https://wiki.linuxfoundation.org/networking/napi for more information on
-NAPI.
-
-
-Known Issues/Troubleshooting
-============================
-
-NOTE:
-  After installing the driver, if your Intel Network Connection is not
-  working, verify in the "In This Release" section of the readme that you have
-  installed the correct driver.
-
-Cable Interoperability Issue with Fujitsu XENPAK Module in SmartBits Chassis
-----------------------------------------------------------------------------
-Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
-Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
-chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
-The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
-Server adapter or the SmartBits. If this situation occurs using a different
-cable assembly may resolve the issue.
-
-Cable Interoperability Issues with HP Procurve 3400cl Switch Port
------------------------------------------------------------------
-Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
-adapter is connected to an HP Procurve 3400cl switch port using short cables
-(1 m or shorter). If this situation occurs, using a longer cable may resolve
-the issue.
-
-Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
-Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
-errors may be received either by the CX4 Server adapter or at the switch. If
-this situation occurs, using a different cable assembly may resolve the issue.
-
-Jumbo Frames System Requirement
--------------------------------
-Memory allocation failures have been observed on Linux systems with 64 MB
-of RAM or less that are running Jumbo Frames.  If you are using Jumbo
-Frames, your system may require more than the advertised minimum
-requirement of 64 MB of system memory.
-
-Performance Degradation with Jumbo Frames
------------------------------------------
-Degradation in throughput performance may be observed in some Jumbo frames
-environments.  If this is observed, increasing the application's socket buffer
-size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
-See the specific application manual and /usr/src/linux*/Documentation/
-networking/ip-sysctl.txt for more details.
-
-Allocating Rx Buffers when Using Jumbo Frames
----------------------------------------------
-Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
-the available memory is heavily fragmented. This issue may be seen with PCI-X
-adapters or with packet split disabled. This can be reduced or eliminated
-by changing the amount of available memory for receive buffer allocation, by
-increasing /proc/sys/vm/min_free_kbytes.
-
-Multiple Interfaces on Same Ethernet Broadcast Network
-------------------------------------------------------
-Due to the default ARP behavior on Linux, it is not possible to have
-one system on two IP networks in the same Ethernet broadcast domain
-(non-partitioned switch) behave as expected.  All Ethernet interfaces
-will respond to IP traffic for any IP address assigned to the system.
-This results in unbalanced receive traffic.
-
-If you have multiple interfaces in a server, do either of the following:
-
-  - Turn on ARP filtering by entering::
-
-      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
-
-  - Install the interfaces in separate broadcast domains - either in
-    different switches or in a switch partitioned to VLANs.
-
-UDP Stress Test Dropped Packet Issue
---------------------------------------
-Under small packets UDP stress test with 10GbE driver, the Linux system
-may drop UDP packets due to the fullness of socket buffers. You may want
-to change the driver's Flow Control variables to the minimum value for
-controlling packet reception.
-
-Tx Hangs Possible Under Stress
-------------------------------
-Under stress conditions, if TX hangs occur, turning off TSO
-"ethtool -K eth0 tso off" may resolve the problem.

+NAPI
+====
+
+NAPI is the event handling mechanism used by the Linux networking stack.
+The name NAPI no longer stands for anything in particular [#]_.
+
+In basic operation the device notifies the host about new events
+via an interrupt.
+The host then schedules a NAPI instance to process the events.
+The device may also be polled for events via NAPI without receiving
+interrupts first (:ref:`busy polling<poll>`).
+
+NAPI processing usually happens in the software interrupt context,
+but there is an option to use :ref:`separate kernel threads<threaded>`
+for NAPI processing.
+
+All in all NAPI abstracts away from the drivers the context and configuration
+of event (packet Rx and Tx) processing.
+
+Driver API
+==========
+
+The two most important elements of NAPI are the struct napi_struct
+and the associated poll method. struct napi_struct holds the state
+of the NAPI instance while the method is the driver-specific event
+handler. The method will typically free Tx packets that have been
+transmitted and process newly received packets.
+
+.. _drv_ctrl:
+
+Control API
+-----------
+
+netif_napi_add() and netif_napi_del() add/remove a NAPI instance
+from the system. The instances are attached to the netdevice passed
+as argument (and will be deleted automatically when netdevice is
+unregistered). Instances are added in a disabled state.
+
+napi_enable() and napi_disable() manage the disabled state.
+A disabled NAPI can't be scheduled and its poll method is guaranteed
+to not be invoked. napi_disable() waits for ownership of the NAPI
+instance to be released.
+
+The control APIs are not idempotent. Control API calls are safe against
+concurrent use of datapath APIs but an incorrect sequence of control API
+calls may result in crashes, deadlocks, or race conditions. For example,
+calling napi_disable() multiple times in a row will deadlock.
+
+Datapath API
+------------
+
+napi_schedule() is the basic method of scheduling a NAPI poll.
+Drivers should call this function in their interrupt handler
+(see :ref:`drv_sched` for more info). A successful call to napi_schedule()
+will take ownership of the NAPI instance.
+
+Later, after NAPI is scheduled, the driver's poll method will be
+called to process the events/packets. The method takes a ``budget``
+argument - drivers can process completions for any number of Tx
+packets but should only process up to ``budget`` number of
+Rx packets. Rx processing is usually much more expensive.
+
+In other words, it is recommended to ignore the budget argument when
+performing TX buffer reclamation to ensure that the reclamation is not
+arbitrarily bounded; however, it is required to honor the budget argument
+for RX processing.
+
+.. warning::
+
+   The ``budget`` argument may be 0 if core tries to only process Tx completions
+   and no Rx packets.
+
+The poll method returns the amount of work done. If the driver still
+has outstanding work to do (e.g. ``budget`` was exhausted)
+the poll method should return exactly ``budget``. In that case,
+the NAPI instance will be serviced/polled again (without the
+need to be scheduled).
+
+If event processing has been completed (all outstanding packets
+processed) the poll method should call napi_complete_done()
+before returning. napi_complete_done() releases the ownership
+of the instance.
+
+.. warning::
+
+   The case of finishing all events and using exactly ``budget``
+   must be handled carefully. There is no way to report this
+   (rare) condition to the stack, so the driver must either
+   not call napi_complete_done() and wait to be called again,
+   or return ``budget - 1``.
+
+   If the ``budget`` is 0 napi_complete_done() should never be called.
+
+Call sequence
+-------------
+
+Drivers should not make assumptions about the exact sequencing
+of calls. The poll method may be called without the driver scheduling
+the instance (unless the instance is disabled). Similarly,
+it's not guaranteed that the poll method will be called, even
+if napi_schedule() succeeded (e.g. if the instance gets disabled).
+
+As mentioned in the :ref:`drv_ctrl` section - napi_disable() and subsequent
+calls to the poll method only wait for the ownership of the instance
+to be released, not for the poll method to exit. This means that
+drivers should avoid accessing any data structures after calling
+napi_complete_done().
+
+.. _drv_sched:
+
+Scheduling and IRQ masking
+--------------------------
+
+Drivers should keep the interrupts masked after scheduling
+the NAPI instance - until NAPI polling finishes any further
+interrupts are unnecessary.
+
+Drivers which have to mask the interrupts explicitly (as opposed
+to IRQ being auto-masked by the device) should use the napi_schedule_prep()
+and __napi_schedule() calls:
+
+.. code-block:: c
+
+  if (napi_schedule_prep(&v->napi)) {
+      mydrv_mask_rxtx_irq(v->idx);
+      /* schedule after masking to avoid races */
+      __napi_schedule(&v->napi);
+  }
+
+IRQ should only be unmasked after a successful call to napi_complete_done():
+
+.. code-block:: c
+
+  if (budget && napi_complete_done(&v->napi, work_done)) {
+    mydrv_unmask_rxtx_irq(v->idx);
+    return min(work_done, budget - 1);
+  }
+
+napi_schedule_irqoff() is a variant of napi_schedule() which takes advantage
+of guarantees given by being invoked in IRQ context (no need to
+mask interrupts). Note that PREEMPT_RT forces all interrupts
+to be threaded so the interrupt may need to be marked ``IRQF_NO_THREAD``
+to avoid issues on real-time kernel configurations.
+
+Instance to queue mapping
+-------------------------
+
+Modern devices have multiple NAPI instances (struct napi_struct) per
+interface. There is no strong requirement on how the instances are
+mapped to queues and interrupts. NAPI is primarily a polling/processing
+abstraction without specific user-facing semantics. That said, most networking
+devices end up using NAPI in fairly similar ways.
+
+NAPI instances most often correspond 1:1:1 to interrupts and queue pairs
+(queue pair is a set of a single Rx and single Tx queue).
+
+In less common cases a NAPI instance may be used for multiple queues
+or Rx and Tx queues can be serviced by separate NAPI instances on a single
+core. Regardless of the queue assignment, however, there is usually still
+a 1:1 mapping between NAPI instances and interrupts.
+
+It's worth noting that the ethtool API uses a "channel" terminology where
+each channel can be either ``rx``, ``tx`` or ``combined``. It's not clear
+what constitutes a channel; the recommended interpretation is to understand
+a channel as an IRQ/NAPI which services queues of a given type. For example,
+a configuration of 1 ``rx``, 1 ``tx`` and 1 ``combined`` channel is expected
+to utilize 3 interrupts, 2 Rx and 2 Tx queues.
+
+User API
+========
+
+User interactions with NAPI depend on NAPI instance ID. The instance IDs
+are only visible to the user thru the ``SO_INCOMING_NAPI_ID`` socket option.
+It's not currently possible to query IDs used by a given device.
+
+Software IRQ coalescing
+-----------------------
+
+NAPI does not perform any explicit event coalescing by default.
+In most scenarios batching happens due to IRQ coalescing which is done
+by the device. There are cases where software coalescing is helpful.
+
+NAPI can be configured to arm a repoll timer instead of unmasking
+the hardware interrupts as soon as all packets are processed.
+The ``gro_flush_timeout`` sysfs configuration of the netdevice
+is reused to control the delay of the timer, while
+``napi_defer_hard_irqs`` controls the number of consecutive empty polls
+before NAPI gives up and goes back to using hardware IRQs.
+
+.. _poll:
+
+Busy polling
+------------
+
+Busy polling allows a user process to check for incoming packets before
+the device interrupt fires. As is the case with any busy polling it trades
+off CPU cycles for lower latency (production uses of NAPI busy polling
+are not well known).
+
+Busy polling is enabled by either setting ``SO_BUSY_POLL`` on
+selected sockets or using the global ``net.core.busy_poll`` and
+``net.core.busy_read`` sysctls. An io_uring API for NAPI busy polling
+also exists.
+
+IRQ mitigation
+---------------
+
+While busy polling is supposed to be used by low latency applications,
+a similar mechanism can be used for IRQ mitigation.
+
+Very high request-per-second applications (especially routing/forwarding
+applications and especially applications using AF_XDP sockets) may not
+want to be interrupted until they finish processing a request or a batch
+of packets.
+
+Such applications can pledge to the kernel that they will perform a busy
+polling operation periodically, and the driver should keep the device IRQs
+permanently masked. This mode is enabled by using the ``SO_PREFER_BUSY_POLL``
+socket option. To avoid system misbehavior the pledge is revoked
+if ``gro_flush_timeout`` passes without any busy poll call.
+
+The NAPI budget for busy polling is lower than the default (which makes
+sense given the low latency intention of normal busy polling). This is
+not the case with IRQ mitigation, however, so the budget can be adjusted
+with the ``SO_BUSY_POLL_BUDGET`` socket option.
+
+.. _threaded:
+
+Threaded NAPI
+-------------
+
+Threaded NAPI is an operating mode that uses dedicated kernel
+threads rather than software IRQ context for NAPI processing.
+The configuration is per netdevice and will affect all
+NAPI instances of that device. Each NAPI instance will spawn a separate
+thread (called ``napi/${ifc-name}-${napi-id}``).
+
+It is recommended to pin each kernel thread to a single CPU, the same
+CPU as the CPU which services the interrupt. Note that the mapping
+between IRQs and NAPI instances may not be trivial (and is driver
+dependent). The NAPI instance IDs will be assigned in the opposite
+order than the process IDs of the kernel threads.
+
+Threaded NAPI is controlled by writing 0/1 to the ``threaded`` file in
+netdev's sysfs directory.

+=======================
+In-Kernel TLS Handshake
+=======================
+
+Overview
+========
+
+Transport Layer Security (TLS) is a Upper Layer Protocol (ULP) that runs
+over TCP. TLS provides end-to-end data integrity and confidentiality in
+addition to peer authentication.
+
+The kernel's kTLS implementation handles the TLS record subprotocol, but
+does not handle the TLS handshake subprotocol which is used to establish
+a TLS session. Kernel consumers can use the API described here to
+request TLS session establishment.
+
+There are several possible ways to provide a handshake service in the
+kernel. The API described here is designed to hide the details of those
+implementations so that in-kernel TLS consumers do not need to be
+aware of how the handshake gets done.
+
+
+User handshake agent
+====================
+
+As of this writing, there is no TLS handshake implementation in the
+Linux kernel. To provide a handshake service, a handshake agent
+(typically in user space) is started in each network namespace where a
+kernel consumer might require a TLS handshake. Handshake agents listen
+for events sent from the kernel that indicate a handshake request is
+waiting.
+
+An open socket is passed to a handshake agent via a netlink operation,
+which creates a socket descriptor in the agent's file descriptor table.
+If the handshake completes successfully, the handshake agent promotes
+the socket to use the TLS ULP and sets the session information using the
+SOL_TLS socket options. The handshake agent returns the socket to the
+kernel via a second netlink operation.
+
+
+Kernel Handshake API
+====================
+
+A kernel TLS consumer initiates a client-side TLS handshake on an open
+socket by invoking one of the tls_client_hello() functions. First, it
+fills in a structure that contains the parameters of the request:
+
+.. code-block:: c
+
+  struct tls_handshake_args {
+        struct socket   *ta_sock;
+        tls_done_func_t ta_done;
+        void            *ta_data;
+        const char      *ta_peername;
+        unsigned int    ta_timeout_ms;
+        key_serial_t    ta_keyring;
+        key_serial_t    ta_my_cert;
+        key_serial_t    ta_my_privkey;
+        unsigned int    ta_num_peerids;
+        key_serial_t    ta_my_peerids[5];
+  };
+
+The @ta_sock field references an open and connected socket. The consumer
+must hold a reference on the socket to prevent it from being destroyed
+while the handshake is in progress. The consumer must also have
+instantiated a struct file in sock->file.
+
+
+@ta_done contains a callback function that is invoked when the handshake
+has completed. Further explanation of this function is in the "Handshake
+Completion" sesction below.
+
+The consumer can provide a NUL-terminated hostname in the @ta_peername
+field that is sent as part of ClientHello. If no peername is provided,
+the DNS hostname associated with the server's IP address is used instead.
+
+The consumer can fill in the @ta_timeout_ms field to force the servicing
+handshake agent to exit after a number of milliseconds. This enables the
+socket to be fully closed once both the kernel and the handshake agent
+have closed their endpoints.
+
+Authentication material such as x.509 certificates, private certificate
+keys, and pre-shared keys are provided to the handshake agent in keys
+that are instantiated by the consumer before making the handshake
+request. The consumer can provide a private keyring that is linked into
+the handshake agent's process keyring in the @ta_keyring field to prevent
+access of those keys by other subsystems.
+
+To request an x.509-authenticated TLS session, the consumer fills in
+the @ta_my_cert and @ta_my_privkey fields with the serial numbers of
+keys containing an x.509 certificate and the private key for that
+certificate. Then, it invokes this function:
+
+.. code-block:: c
+
+  ret = tls_client_hello_x509(args, gfp_flags);
+
+The function returns zero when the handshake request is under way. A
+zero return guarantees the callback function @ta_done will be invoked
+for this socket. The function returns a negative errno if the handshake
+could not be started. A negative errno guarantees the callback function
+@ta_done will not be invoked on this socket.
+
+
+To initiate a client-side TLS handshake with a pre-shared key, use:
+
+.. code-block:: c
+
+  ret = tls_client_hello_psk(args, gfp_flags);
+
+However, in this case, the consumer fills in the @ta_my_peerids array
+with serial numbers of keys containing the peer identities it wishes
+to offer, and the @ta_num_peerids field with the number of array
+entries it has filled in. The other fields are filled in as above.
+
+
+To initiate an anonymous client-side TLS handshake use:
+
+.. code-block:: c
+
+  ret = tls_client_hello_anon(args, gfp_flags);
+
+The handshake agent presents no peer identity information to the remote
+during this type of handshake. Only server authentication (ie the client
+verifies the server's identity) is performed during the handshake. Thus
+the established session uses encryption only.
+
+
+Consumers that are in-kernel servers use:
+
+.. code-block:: c
+
+  ret = tls_server_hello_x509(args, gfp_flags);
+
+or
+
+.. code-block:: c
+
+  ret = tls_server_hello_psk(args, gfp_flags);
+
+The argument structure is filled in as above.
+
+
+If the consumer needs to cancel the handshake request, say, due to a ^C
+or other exigent event, the consumer can invoke:
+
+.. code-block:: c
+
+  bool tls_handshake_cancel(sock);
+
+This function returns true if the handshake request associated with
+@sock has been canceled. The consumer's handshake completion callback
+will not be invoked. If this function returns false, then the consumer's
+completion callback has already been invoked.
+
+
+Handshake Completion
+====================
+
+When the handshake agent has completed processing, it notifies the
+kernel that the socket may be used by the consumer again. At this point,
+the consumer's handshake completion callback, provided in the @ta_done
+field in the tls_handshake_args structure, is invoked.
+
+The synopsis of this function is:
+
+.. code-block:: c
+
+  typedef void	(*tls_done_func_t)(void *data, int status,
+                                   key_serial_t peerid);
+
+The consumer provides a cookie in the @ta_data field of the
+tls_handshake_args structure that is returned in the @data parameter of
+this callback. The consumer uses the cookie to match the callback to the
+thread waiting for the handshake to complete.
+
+The success status of the handshake is returned via the @status
+parameter:

+The @peerid parameter contains the serial number of a key containing the
+remote peer's identity or the value TLS_NO_PEERID if the session is not
+authenticated.
+
+A best practice is to close and destroy the socket immediately if the
+handshake failed.
+
+
+Other considerations
+--------------------
+
+While a handshake is under way, the kernel consumer must alter the
+socket's sk_data_ready callback function to ignore all incoming data.
+Once the handshake completion callback function has been invoked, normal
+receive operation can be resumed.
+
+Once a TLS session is established, the consumer must provide a buffer
+for and then examine the control message (CMSG) that is part of every
+subsequent sock_recvmsg(). Each control message indicates whether the
+received message data is TLS record data or session metadata.
+
+See tls.rst for details on how a kTLS consumer recognizes incoming
+(decrypted) application data, alerts, and handshake packets once the
+socket has been promoted to use the TLS ULP.

+========================================
+Linux Kernel Contribution Maturity Model
+========================================
+
+
+Background
+==========
+
+As a part of the 2021 Linux Kernel Maintainers’ Summit, there was a
+`discussion <https://lwn.net/Articles/870581/>`_ about the challenges in
+recruiting kernel maintainers as well as maintainer succession.  Some of
+the conclusions from that discussion included that companies which are a
+part of the Linux Kernel community need to allow engineers to be
+maintainers as part of their job, so they can grow into becoming
+respected leaders and eventually, kernel maintainers.  To support a
+strong talent pipeline, developers should be allowed and encouraged to
+take on upstream contributions such as reviewing other people’s patches,
+refactoring kernel infrastructure, and writing documentation.
+
+To that end, the Linux Foundation Technical Advisory Board (TAB)
+proposes this Linux Kernel Contribution Maturity Model. These common
+expectations for upstream community engagement aim to increase the
+influence of individual developers, increase the collaboration of
+organizations, and improve the overall health of the Linux Kernel
+ecosystem.
+
+The TAB urges organizations to continuously evaluate their Open Source
+maturity model and commit to improvements to align with this model.  To
+be effective, this evaluation should incorporate feedback from across
+the organization, including management and developers at all seniority
+levels.  In the spirit of Open Source, we encourage organizations to
+publish their evaluations and plans to improve their engagement with the
+upstream community.
+
+Level 0
+=======
+
+* Software Engineers are not allowed to contribute patches to the Linux
+  kernel.
+
+
+Level 1
+=======
+
+* Software Engineers are allowed to contribute patches to the Linux
+  kernel, either as part of their job responsibilities or on their own
+  time.
+
+Level 2
+=======
+
+* Software Engineers are expected to contribute to the Linux Kernel as
+  part of their job responsibilities.
+* Software Engineers will be supported to attend Linux-related
+  conferences as a part of their job.
+* A Software Engineer’s upstream code contributions will be considered
+  in promotion and performance reviews.
+
+Level 3
+=======
+
+* Software Engineers are expected to review patches (including patches
+  authored by engineers from other companies) as part of their job
+  responsibilities
+* Contributing presentations or papers to Linux-related or academic
+  conferences (such those organized by the Linux Foundation, Usenix,
+  ACM, etc.), are considered part of an engineer’s work.
+* A Software Engineer’s community contributions will be considered in
+  promotion and performance reviews.
+* Organizations will regularly report metrics of their open source
+  contributions and track these metrics over time.  These metrics may be
+  published only internally within the organization, or at the
+  organization’s discretion, some or all may be published externally.
+  Metrics that are strongly suggested include:
+
+  * The number of upstream kernel contributions by team or organization
+    (e.g., all people reporting up to a manager, director, or VP).
+  * The percentage of kernel developers who have made upstream
+    contributions relative to the total kernel developers in the
+    organization.
+  * The time interval between kernels used in the organization’s servers
+    and/or products, and the publication date of the upstream kernel
+    upon which the internal kernel is based.
+  * The number of out-of-tree commits present in internal kernels.
+
+Level 4
+=======
+
+* Software Engineers are encouraged to spend a portion of their work
+  time focused on Upstream Work, which is defined as reviewing patches,
+  serving on program committees, improving core project infrastructure
+  such as writing or maintaining tests, upstream tech debt reduction,
+  writing documentation, etc.
+* Software Engineers are supported in helping to organize Linux-related
+  conferences.
+* Organizations will consider community member feedback in official
+  performance reviews.
+
+Level 5
+=======
+
+* Upstream kernel development is considered a formal job position, with
+  at least a third of the engineer’s time spent doing Upstream Work.
+* Organizations will actively seek out community member feedback as a
+  factor in official performance reviews.
+* Organizations will regularly report internally on the ratio of
+  Upstream Work to work focused on directly pursuing business goals.

+
+The arguments are split into three groups: an array of key-value pairs, a CPU
+set, and some flags. The key-value pairs are supplied with a count. Userspace
+must prepopulate the key field for each element, and the kernel will fill in the
+value if the key is recognized. If a key is unknown to the kernel, its key field
+will be cleared to -1, and its value set to 0. The CPU set is defined by
+CPU_SET(3). For value-like keys (eg. vendor/arch/impl), the returned value will
+be only be valid if all CPUs in the given set have the same value. Otherwise -1
+will be returned. For boolean-like keys, the value returned will be a logical
+AND of the values for the specified CPUs. Usermode can supply NULL for cpus and
+0 for cpu_count as a shortcut for all online CPUs. There are currently no flags,
+this value must be zero for future compatibility.
+
+On success 0 is returned, on failure a negative error code is returned.
+
+The following keys are defined:
+
+* :c:macro:`RISCV_HWPROBE_KEY_MVENDORID`: Contains the value of ``mvendorid``,
+  as defined by the RISC-V privileged architecture specification.
+
+* :c:macro:`RISCV_HWPROBE_KEY_MARCHID`: Contains the value of ``marchid``, as
+  defined by the RISC-V privileged architecture specification.
+
+* :c:macro:`RISCV_HWPROBE_KEY_MIMPLID`: Contains the value of ``mimplid``, as
+  defined by the RISC-V privileged architecture specification.
+
+* :c:macro:`RISCV_HWPROBE_KEY_BASE_BEHAVIOR`: A bitmask containing the base
+  user-visible behavior that this kernel supports.  The following base user ABIs
+  are defined:
+
+  * :c:macro:`RISCV_HWPROBE_BASE_BEHAVIOR_IMA`: Support for rv32ima or
+    rv64ima, as defined by version 2.2 of the user ISA and version 1.10 of the
+    privileged ISA, with the following known exceptions (more exceptions may be
+    added, but only if it can be demonstrated that the user ABI is not broken):
+
+    * The :fence.i: instruction cannot be directly executed by userspace
+      programs (it may still be executed in userspace via a
+      kernel-controlled mechanism such as the vDSO).
+
+* :c:macro:`RISCV_HWPROBE_KEY_IMA_EXT_0`: A bitmask containing the extensions
+  that are compatible with the :c:macro:`RISCV_HWPROBE_BASE_BEHAVIOR_IMA`:
+  base system behavior.
+
+  * :c:macro:`RISCV_HWPROBE_IMA_FD`: The F and D extensions are supported, as
+    defined by commit cd20cee ("FMIN/FMAX now implement
+    minimumNumber/maximumNumber, not minNum/maxNum") of the RISC-V ISA manual.
+
+  * :c:macro:`RISCV_HWPROBE_IMA_C`: The C extension is supported, as defined
+    by version 2.2 of the RISC-V ISA manual.
+
+* :c:macro:`RISCV_HWPROBE_KEY_CPUPERF_0`: A bitmask that contains performance
+  information about the selected set of processors.
+
+  * :c:macro:`RISCV_HWPROBE_MISALIGNED_UNKNOWN`: The performance of misaligned
+    accesses is unknown.
+
+  * :c:macro:`RISCV_HWPROBE_MISALIGNED_EMULATED`: Misaligned accesses are
+    emulated via software, either in or below the kernel.  These accesses are
+    always extremely slow.
+
+  * :c:macro:`RISCV_HWPROBE_MISALIGNED_SLOW`: Misaligned accesses are supported
+    in hardware, but are slower than the cooresponding aligned accesses
+    sequences.
+
+  * :c:macro:`RISCV_HWPROBE_MISALIGNED_FAST`: Misaligned accesses are supported
+    in hardware and are faster than the cooresponding aligned accesses

+    not supported at all and will generate a misaligned address fault.

+Patchwork
+---------
+
+RISC-V has a patchwork instance, where the status of patches can be checked:
+
+  https://patchwork.kernel.org/project/linux-riscv/list/
+
+If your patch does not appear in the default view, the RISC-V maintainers have
+likely either requested changes, or expect it to be applied to another tree.
+
+Automation runs against this patchwork instance, building/testing patches as
+they arrive. The automation applies patches against the current HEAD of the
+RISC-V `for-next` and `fixes` branches, depending on whether the patch has been
+detected as a fix. Failing those, it will use the RISC-V `master` branch.
+The exact commit to which a series has been applied will be noted on patchwork.
+Patches for which any of the checks fail are unlikely to be applied and in most
+cases will need to be resubmitted.

+This file documents the 'multi-link structure' introduced in 2015 with
+the Skylake processor and recently extended in newer Intel platforms
+
+HDaudio existing link mapping (2015 addition in SkyLake)
+========================================================
+
+External HDAudio codecs are handled with link #0, while iDISP codec
+for HDMI/DisplayPort is handled with link #1.
+
+The only change to the 2015 definitions is the declaration of the
+LCAP.ALT=0x0 - since the ALT bit was previously reserved, this is a
+backwards-compatible change.
+
+LCTL.SPA and LCTL.CPA are automatically set when exiting reset. They
+are only used in existing drivers when the SCF value needs to be
+corrected.

+OPTEE_INSECURE_LOAD_IMAGE Kconfig option
+----------------------------------------
+
+The OPTEE_INSECURE_LOAD_IMAGE Kconfig option enables the ability to load the
+BL32 OP-TEE image from the kernel after the kernel boots, rather than loading
+it from the firmware before the kernel boots. This also requires enabling the
+corresponding option in Trusted Firmware for Arm. The Trusted Firmware for Arm
+documentation [8] explains the security threat associated with enabling this as
+well as mitigations at the firmware and platform level.
+
+There are additional attack vectors/mitigations for the kernel that should be
+addressed when using this option.
+
+1. Boot chain security.
+
+   * Attack vector: Replace the OP-TEE OS image in the rootfs to gain control of
+     the system.
+
+   * Mitigation: There must be boot chain security that verifies the kernel and
+     rootfs, otherwise an attacker can modify the loaded OP-TEE binary by
+     modifying it in the rootfs.
+
+2. Alternate boot modes.
+
+   * Attack vector: Using an alternate boot mode (i.e. recovery mode), the
+     OP-TEE driver isn't loaded, leaving the SMC hole open.
+
+   * Mitigation: If there are alternate methods of booting the device, such as a
+     recovery mode, it should be ensured that the same mitigations are applied
+     in that mode.
+
+3. Attacks prior to SMC invocation.
+
+   * Attack vector: Code that is executed prior to issuing the SMC call to load
+     OP-TEE can be exploited to then load an alternate OS image.
+
+   * Mitigation: The OP-TEE driver must be loaded before any potential attack
+     vectors are opened up. This should include mounting of any modifiable
+     filesystems, opening of network ports or communicating with external
+     devices (e.g. USB).
+
+4. Blocking SMC call to load OP-TEE.
+
+   * Attack vector: Prevent the driver from being probed, so the SMC call to
+     load OP-TEE isn't executed when desired, leaving it open to being executed
+     later and loading a modified OS.
+
+   * Mitigation: It is recommended to build the OP-TEE driver as builtin driver
+     rather than as a module to prevent exploits that may cause the module to
+     not be loaded.

 event (in both user and kernel space). User programs should use a separate file
 to request deletes than the one used for registration due to this.
 
-Status
-------
-When tools attach/record user based events the status of the event is updated
-in realtime. This allows user programs to only incur the cost of the write() or
-writev() calls when something is actively attached to the event.
-
-User programs call mmap() on /sys/kernel/tracing/user_events_status to
-check the status for each event that is registered. The bit to check in the
-file is given back after the register ioctl() via user_reg.status_bit. The bit
-is always in little-endian format. Programs can check if the bit is set either
-using a byte-wise index with a mask or a long-wise index with a little-endian
-mask.
+**NOTE:** By default events will auto-delete when there are no references left
+to the event. Flags in the future may change this logic.
 
-Currently the size of user_events_status is a single page, however, custom
-kernel configurations can change this size to allow more user based events. In
-all cases the size of the file is a multiple of a page size.
+Unregistering
+-------------
+If after registering an event it is no longer wanted to be updated then it can
+be disabled via ioctl() out to the /sys/kernel/tracing/user_events_data file.
+The command to issue is DIAG_IOCSUNREG. This is different than deleting, where
+deleting actually removes the event from the system. Unregistering simply tells
+the kernel your process is no longer interested in updates to the event.
 
-For example, if the register ioctl() gives back a status_bit of 3 you would
-check byte 0 (3 / 8) of the returned mmap data and then AND the result with 8
-(1 << (3 % 8)) to see if anything is attached to that event.
+This command takes a packed struct user_unreg as an argument::

+Status
+------
+When tools attach/record user based events the status of the event is updated
+in realtime. This allows user programs to only incur the cost of the write() or
+writev() calls when something is actively attached to the event.
 
-  if (status_page[index] & mask) {
-        /* Enabled */
-  }
+The kernel will update the specified bit that was registered for the event as
+tools attach/detach from the event. User programs simply check if the bit is set
+to see if something is attached or not.
 
 Administrators can easily check the status of all registered events by reading
 the user_events_status file directly via a terminal. The output is as follows::
 
-  Byte:Name [# Comments]
+  Name [# Comments]
   ...
 
   Active: ActiveCount
   Busy: BusyCount
-  Max: MaxCount
 
 For example, on a system that has a single event the output looks like this::
 
-  1:test
+  test
 
   Active: 1
   Busy: 0
-  Max: 32768
 
 If a user enables the user event via ftrace, the output would change to this::
 
-  1:test # Used by ftrace
+  test # Used by ftrace
 
   Active: 1
   Busy: 1
-  Max: 32768
-
-**NOTE:** *A status bit of 0 will never be returned. This allows user programs
-to have a bit that can be used on error cases.*
