 is, uncharge task's pages from the old cgroup and charge them to the new cgroup.

+Cross-Thread Return Address Predictions
+=======================================
+
+Certain AMD and Hygon processors are subject to a cross-thread return address
+predictions vulnerability. When running in SMT mode and one sibling thread
+transitions out of C0 state, the other sibling thread could use return target
+predictions from the sibling thread that transitioned out of C0.
+
+The Spectre v2 mitigations protect the Linux kernel, as it fills the return
+address prediction entries with safe targets when context switching to the idle
+thread. However, KVM does allow a VMM to prevent exiting guest mode when
+transitioning out of C0. This could result in a guest-controlled return target

+
+The following CVE entry is related to this issue:
+
+   ==============  =======================================
+   CVE-2022-27672  Cross-Thread Return Address Predictions
+   ==============  =======================================
+
+Problem
+-------
+
+Affected SMT-capable processors support 1T and 2T modes of execution when SMT
+is enabled. In 2T mode, both threads in a core are executing code. For the
+processor core to enter 1T mode, it is required that one of the threads
+requests to transition out of the C0 state. This can be communicated with the
+HLT instruction or with an MWAIT instruction that requests non-C0.
+When the thread re-enters the C0 state, the processor transitions back
+to 2T mode, assuming the other thread is also still in C0 state.
+
+In affected processors, the return address predictor (RAP) is partitioned
+depending on the SMT mode. For instance, in 2T mode each thread uses a private
+16-entry RAP, but in 1T mode, the active thread uses a 32-entry RAP. Upon
+transition between 1T/2T mode, the RAP contents are not modified but the RAP
+pointers (which control the next return target to use for predictions) may
+change. This behavior may result in return targets from one SMT thread being
+used by RET predictions in the sibling thread following a 1T/2T switch. In
+particular, a RET instruction executed immediately after a transition to 1T may
+use a return target from the thread that just became idle. In theory, this
+could lead to information disclosure if the return targets used do not come
+from trustworthy code.
+
+Attack scenarios
+----------------
+
+An attack can be mounted on affected processors by performing a series of CALL
+instructions with targeted return locations and then transitioning out of C0
+state.
+
+Mitigation mechanism
+--------------------
+
+Before entering idle state, the kernel context switches to the idle thread. The
+context switch fills the RAP entries (referred to as the RSB in Linux) with safe
+targets by performing a sequence of CALL instructions.
+
+Prevent a guest VM from directly putting the processor into an idle state by
+intercepting HLT and MWAIT instructions.
+
+Both mitigations are required to fully address this issue.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+
+Use existing Spectre v2 mitigations that will fill the RSB on context switch.
+
+Mitigation control for KVM - module parameter
+---------------------------------------------
+
+By default, the KVM hypervisor mitigates this issue by intercepting guest
+attempts to transition out of C0. A VMM can use the KVM_CAP_X86_DISABLE_EXITS
+capability to override those interceptions, but since this is not common, the
+mitigation that covers this path is not enabled by default.
+
+The mitigation for the KVM_CAP_X86_DISABLE_EXITS capability can be turned on
+using the boolean module parameter mitigate_smt_rsb, e.g.:
+        kvm.mitigate_smt_rsb=1

+GDS - Gather Data Sampling
+==========================
+
+Gather Data Sampling is a hardware vulnerability which allows unprivileged
+speculative access to data which was previously stored in vector registers.
+
+Problem
+-------
+When a gather instruction performs loads from memory, different data elements
+are merged into the destination vector register. However, when a gather
+instruction that is transiently executed encounters a fault, stale data from
+architectural or internal vector registers may get transiently forwarded to the
+destination vector register instead. This will allow a malicious attacker to
+infer stale data using typical side channel techniques like cache timing
+attacks. GDS is a purely sampling-based attack.
+
+The attacker uses gather instructions to infer the stale vector register data.
+The victim does not need to do anything special other than use the vector
+registers. The victim does not need to use gather instructions to be
+vulnerable.
+
+Because the buffers are shared between Hyper-Threads cross Hyper-Thread attacks
+are possible.
+
+Attack scenarios
+----------------
+Without mitigation, GDS can infer stale data across virtually all
+permission boundaries:
+
+	Non-enclaves can infer SGX enclave data
+	Userspace can infer kernel data
+	Guests can infer data from hosts
+	Guest can infer guest from other guests
+	Users can infer data from other users
+
+Because of this, it is important to ensure that the mitigation stays enabled in
+lower-privilege contexts like guests and when running outside SGX enclaves.
+
+The hardware enforces the mitigation for SGX. Likewise, VMMs should  ensure
+that guests are not allowed to disable the GDS mitigation. If a host erred and
+allowed this, a guest could theoretically disable GDS mitigation, mount an
+attack, and re-enable it.
+
+Mitigation mechanism
+--------------------
+This issue is mitigated in microcode. The microcode defines the following new
+bits:
+
+ ================================   ===   ============================
+ IA32_ARCH_CAPABILITIES[GDS_CTRL]   R/O   Enumerates GDS vulnerability
+                                          and mitigation support.
+ IA32_ARCH_CAPABILITIES[GDS_NO]     R/O   Processor is not vulnerable.
+ IA32_MCU_OPT_CTRL[GDS_MITG_DIS]    R/W   Disables the mitigation
+                                          0 by default.
+ IA32_MCU_OPT_CTRL[GDS_MITG_LOCK]   R/W   Locks GDS_MITG_DIS=0. Writes
+                                          to GDS_MITG_DIS are ignored
+                                          Can't be cleared once set.
+ ================================   ===   ============================
+
+GDS can also be mitigated on systems that don't have updated microcode by
+disabling AVX. This can be done by setting gather_data_sampling="force" or
+"clearcpuid=avx" on the kernel command-line.
+
+If used, these options will disable AVX use by turning off XSAVE YMM support.
+However, the processor will still enumerate AVX support.  Userspace that
+does not follow proper AVX enumeration to check both AVX *and* XSAVE YMM
+support will break.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The mitigation can be disabled by setting "gather_data_sampling=off" or
+"mitigations=off" on the kernel command line. Not specifying either will default
+to the mitigation being enabled. Specifying "gather_data_sampling=force" will
+use the microcode mitigation when available or disable AVX on affected systems
+where the microcode hasn't been updated to include the mitigation.
+
+GDS System Information
+------------------------
+The kernel provides vulnerability status information through sysfs. For
+GDS this can be accessed by the following sysfs file:
+
+/sys/devices/system/cpu/vulnerabilities/gather_data_sampling
+
+The possible values contained in this file are:

+Register File Data Sampling (RFDS)
+==================================
+
+Register File Data Sampling (RFDS) is a microarchitectural vulnerability that
+only affects Intel Atom parts(also branded as E-cores). RFDS may allow
+a malicious actor to infer data values previously used in floating point
+registers, vector registers, or integer registers. RFDS does not provide the
+ability to choose which data is inferred. CVE-2023-28746 is assigned to RFDS.
+
+Affected Processors
+===================
+Below is the list of affected Intel processors [#f1]_:
+
+   ===================  ============
+   Common name          Family_Model
+   ===================  ============
+   ATOM_GOLDMONT           06_5CH
+   ATOM_GOLDMONT_D         06_5FH

+   ATOM_GRACEMONT          06_BEH
+   RAPTORLAKE_S            06_BFH
+   ===================  ============
+
+As an exception to this table, Intel Xeon E family parts ALDERLAKE(06_97H) and
+RAPTORLAKE(06_B7H) codenamed Catlow are not affected. They are reported as
+vulnerable in Linux because they share the same family/model with an affected
+part. Unlike their affected counterparts, they do not enumerate RFDS_CLEAR or
+CPUID.HYBRID. This information could be used to distinguish between the
+affected and unaffected parts, but it is deemed not worth adding complexity as
+the reporting is fixed automatically when these parts enumerate RFDS_NO.
+
+Mitigation
+==========
+Intel released a microcode update that enables software to clear sensitive
+information using the VERW instruction. Like MDS, RFDS deploys the same
+mitigation strategy to force the CPU to clear the affected buffers before an
+attacker can extract the secrets. This is achieved by using the otherwise
+unused and obsolete VERW instruction in combination with a microcode update.
+The microcode clears the affected CPU buffers when the VERW instruction is
+executed.
+
+Mitigation points
+-----------------
+VERW is executed by the kernel before returning to user space, and by KVM
+before VMentry. None of the affected cores support SMT, so VERW is not required
+at C-state transitions.
+
+New bits in IA32_ARCH_CAPABILITIES
+----------------------------------
+Newer processors and microcode update on existing affected processors added new
+bits to IA32_ARCH_CAPABILITIES MSR. These bits can be used to enumerate
+vulnerability and mitigation capability:
+
+- Bit 27 - RFDS_NO - When set, processor is not affected by RFDS.
+- Bit 28 - RFDS_CLEAR - When set, processor is affected by RFDS, and has the
+  microcode that clears the affected buffers on VERW execution.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The kernel command line allows to control RFDS mitigation at boot time with the
+parameter "reg_file_data_sampling=". The valid arguments are:
+
+  ==========  =================================================================
+  on          If the CPU is vulnerable, enable mitigation; CPU buffer clearing
+              on exit to userspace and before entering a VM.
+  off         Disables mitigation.
+  ==========  =================================================================
+
+Mitigation default is selected by CONFIG_MITIGATION_RFDS.
+
+Mitigation status information
+-----------------------------
+The Linux kernel provides a sysfs interface to enumerate the current
+vulnerability status of the system: whether the system is vulnerable, and
+which mitigations are active. The relevant sysfs file is:
+
+	/sys/devices/system/cpu/vulnerabilities/reg_file_data_sampling
+
+The possible values in this file are:
+
+  .. list-table::
+

+       - The processor is not vulnerable
+     * - 'Vulnerable'
+       - The processor is vulnerable, but no mitigation enabled
+     * - 'Vulnerable: No microcode'
+       - The processor is vulnerable but microcode is not updated.

+Speculative Return Stack Overflow (SRSO)
+========================================
+
+This is a mitigation for the speculative return stack overflow (SRSO)
+vulnerability found on AMD processors. The mechanism is by now the well
+known scenario of poisoning CPU functional units - the Branch Target
+Buffer (BTB) and Return Address Predictor (RAP) in this case - and then
+tricking the elevated privilege domain (the kernel) into leaking
+sensitive data.
+
+AMD CPUs predict RET instructions using a Return Address Predictor (aka
+Return Address Stack/Return Stack Buffer). In some cases, a non-architectural
+CALL instruction (i.e., an instruction predicted to be a CALL but is
+not actually a CALL) can create an entry in the RAP which may be used
+to predict the target of a subsequent RET instruction.
+
+The specific circumstances that lead to this varies by microarchitecture
+but the concern is that an attacker can mis-train the CPU BTB to predict
+non-architectural CALL instructions in kernel space and use this to
+control the speculative target of a subsequent kernel RET, potentially
+leading to information disclosure via a speculative side-channel.
+
+The issue is tracked under CVE-2023-20569.

+
+In order to exploit vulnerability, an attacker needs to:
+
+ - gain local access on the machine
+
+ - break kASLR
+
+ - find gadgets in the running kernel in order to use them in the exploit
+
+ - potentially create and pin an additional workload on the sibling
+   thread, depending on the microarchitecture (not necessary on fam 0x19)
+
+ - run the exploit
+
+Considering the performance implications of each mitigation type, the
+default one is 'Mitigation: safe RET' which should take care of most
+attack vectors, including the local User->Kernel one.
+
+As always, the user is advised to keep her/his system up-to-date by
+applying software updates regularly.
+
+The default setting will be reevaluated when needed and especially when
+new attack vectors appear.
+
+As one can surmise, 'Mitigation: safe RET' does come at the cost of some
+performance depending on the workload. If one trusts her/his userspace
+and does not want to suffer the performance impact, one can always
+disable the mitigation with spec_rstack_overflow=off.
+
+Similarly, 'Mitigation: IBPB' is another full mitigation type employing
+an indrect branch prediction barrier after having applied the required
+microcode patch for one's system. This mitigation comes also at
+a performance cost.
+
+Mitigation: safe RET
+--------------------
+
+The mitigation works by ensuring all RET instructions speculate to
+a controlled location, similar to how speculation is controlled in the
+retpoline sequence.  To accomplish this, the __x86_return_thunk forces
+the CPU to mispredict every function return using a 'safe return'
+sequence.
+
+To ensure the safety of this mitigation, the kernel must ensure that the
+safe return sequence is itself free from attacker interference.  In Zen3
+and Zen4, this is accomplished by creating a BTB alias between the
+untraining function srso_alias_untrain_ret() and the safe return
+function srso_alias_safe_ret() which results in evicting a potentially
+poisoned BTB entry and using that safe one for all function returns.
+
+In older Zen1 and Zen2, this is accomplished using a reinterpretation
+technique similar to Retbleed one: srso_untrain_ret() and
+srso_safe_ret().

+Coordination with other groups
+------------------------------
+
+The kernel security team strongly recommends that reporters of potential
+security issues NEVER contact the "linux-distros" mailing list until
+AFTER discussing it with the kernel security team.  Do not Cc: both
+lists at once.  You may contact the linux-distros mailing list after a
+fix has been agreed on and you fully understand the requirements that
+doing so will impose on you and the kernel community.

-may delay the bug handling. If a reporter wishes to have a CVE identifier
-assigned ahead of public disclosure, they will need to contact the private

-before a patch is provided, it is desirable to mention it in the commit
-message if the reporter agrees.

+penalties: forcing them to wait and only allowing one core to execute split
+locks at a time.
+
+These mitigations can make those bad applications unbearably slow. Setting
+split_lock_mitigate=0 may restore some application performance, but will also
+increase system exposure to denial of service attacks from split lock users.

+0 Disable the mitigation mode - just warns the split lock on kernel log

+1 Enable the mitigation mode (this is the default) - penalizes the split
+  lockers with intentional performance degradation.

+=====================
+BPF_MAP_TYPE_LPM_TRIE
+=====================
+
+.. note::
+   - ``BPF_MAP_TYPE_LPM_TRIE`` was introduced in kernel version 4.11
+
+``BPF_MAP_TYPE_LPM_TRIE`` provides a longest prefix match algorithm that
+can be used to match IP addresses to a stored set of prefixes.
+Internally, data is stored in an unbalanced trie of nodes that uses
+``prefixlen,data`` pairs as its keys. The ``data`` is interpreted in
+network byte order, i.e. big endian, so ``data[0]`` stores the most
+significant byte.
+
+LPM tries may be created with a maximum prefix length that is a multiple
+of 8, in the range from 8 to 2048. The key used for lookup and update
+operations is a ``struct bpf_lpm_trie_key_u8``, extended by
+``max_prefixlen/8`` bytes.
+
+- For IPv4 addresses the data length is 4 bytes
+- For IPv6 addresses the data length is 16 bytes
+
+The value type stored in the LPM trie can be any user defined type.
+
+.. note::
+   When creating a map of type ``BPF_MAP_TYPE_LPM_TRIE`` you must set the
+   ``BPF_F_NO_PREALLOC`` flag.
+
+Usage
+=====
+
+Kernel BPF
+----------
+
+.. c:function::
+   void *bpf_map_lookup_elem(struct bpf_map *map, const void *key)
+
+The longest prefix entry for a given data value can be found using the
+``bpf_map_lookup_elem()`` helper. This helper returns a pointer to the
+value associated with the longest matching ``key``, or ``NULL`` if no
+entry was found.
+
+The ``key`` should have ``prefixlen`` set to ``max_prefixlen`` when
+performing longest prefix lookups. For example, when searching for the
+longest prefix match for an IPv4 address, ``prefixlen`` should be set to
+``32``.
+
+.. c:function::
+   long bpf_map_update_elem(struct bpf_map *map, const void *key, const void *value, u64 flags)
+
+Prefix entries can be added or updated using the ``bpf_map_update_elem()``
+helper. This helper replaces existing elements atomically.
+
+``bpf_map_update_elem()`` returns ``0`` on success, or negative error in
+case of failure.
+
+ .. note::
+    The flags parameter must be one of BPF_ANY, BPF_NOEXIST or BPF_EXIST,
+    but the value is ignored, giving BPF_ANY semantics.
+
+.. c:function::
+   long bpf_map_delete_elem(struct bpf_map *map, const void *key)
+
+Prefix entries can be deleted using the ``bpf_map_delete_elem()``
+helper. This helper will return 0 on success, or negative error in case
+of failure.
+
+Userspace
+---------
+
+Access from userspace uses libbpf APIs with the same names as above, with
+the map identified by ``fd``.
+
+.. c:function::
+   int bpf_map_get_next_key (int fd, const void *cur_key, void *next_key)
+
+A userspace program can iterate through the entries in an LPM trie using
+libbpf's ``bpf_map_get_next_key()`` function. The first key can be
+fetched by calling ``bpf_map_get_next_key()`` with ``cur_key`` set to
+``NULL``. Subsequent calls will fetch the next key that follows the
+current key. ``bpf_map_get_next_key()`` returns ``0`` on success,
+``-ENOENT`` if ``cur_key`` is the last key in the trie, or negative
+error in case of failure.
+
+``bpf_map_get_next_key()`` will iterate through the LPM trie elements
+from leftmost leaf first. This means that iteration will return more
+specific keys before less specific ones.
+
+Examples
+========
+
+Please see ``tools/testing/selftests/bpf/test_lpm_map.c`` for examples
+of LPM trie usage from userspace. The code snippets below demonstrate
+API usage.
+
+Kernel BPF
+----------
+
+The following BPF code snippet shows how to declare a new LPM trie for IPv4
+address prefixes:
+
+.. code-block:: c
+
+    #include <linux/bpf.h>
+    #include <bpf/bpf_helpers.h>
+
+    struct ipv4_lpm_key {
+            __u32 prefixlen;
+            __u32 data;
+    };
+
+    struct {
+            __uint(type, BPF_MAP_TYPE_LPM_TRIE);
+            __type(key, struct ipv4_lpm_key);
+            __type(value, __u32);
+            __uint(map_flags, BPF_F_NO_PREALLOC);
+            __uint(max_entries, 255);
+    } ipv4_lpm_map SEC(".maps");
+
+The following BPF code snippet shows how to lookup by IPv4 address:
+
+.. code-block:: c
+
+    void *lookup(__u32 ipaddr)
+    {
+            struct ipv4_lpm_key key = {
+                    .prefixlen = 32,
+                    .data = ipaddr
+            };
+
+            return bpf_map_lookup_elem(&ipv4_lpm_map, &key);
+    }
+
+Userspace
+---------
+
+The following snippet shows how to insert an IPv4 prefix entry into an
+LPM trie:
+
+.. code-block:: c
+
+    int add_prefix_entry(int lpm_fd, __u32 addr, __u32 prefixlen, struct value *value)
+    {
+            struct ipv4_lpm_key ipv4_key = {
+                    .prefixlen = prefixlen,
+                    .data = addr
+            };
+            return bpf_map_update_elem(lpm_fd, &ipv4_key, value, BPF_ANY);
+    }
+
+The following snippet shows a userspace program walking through the entries
+of an LPM trie:
+
+
+.. code-block:: c
+
+    #include <bpf/libbpf.h>
+    #include <bpf/bpf.h>
+
+    void iterate_lpm_trie(int map_fd)
+    {
+            struct ipv4_lpm_key *cur_key = NULL;
+            struct ipv4_lpm_key next_key;
+            struct value value;
+            int err;
+
+            for (;;) {
+                    err = bpf_map_get_next_key(map_fd, cur_key, &next_key);
+                    if (err)
+                            break;
+
+                    bpf_map_lookup_elem(map_fd, &next_key, &value);
+
+                    /* Use key and value here */
+
+                    cur_key = &next_key;
+            }
+    }

 --------------
 
-A client driver typically only has to conditionally change its DMA map
-routine to use the mapping function :c:func:`pci_p2pdma_map_sg()` instead
-of the usual :c:func:`dma_map_sg()` function. Memory mapped in this

-The client may also, optionally, make use of
-:c:func:`is_pci_p2pdma_page()` to determine when to use the P2P mapping
-functions and when to use the regular mapping functions. In some
-situations, it may be more appropriate to use a flag to indicate a
-given request is P2P memory and map appropriately. It is important to
-ensure that struct pages that back P2P memory stay out of code that
-does not have support for them as other code may treat the pages as
-regular memory which may not be appropriate.
+A client driver only has to use the mapping API :c:func:`dma_map_sg()`

+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.

+Dynamic RX Buffers (DRB)
+------------------------
+
+Each RX descriptor in the RX ring is a single memory page (which is either 4KB

+
+   **Corner case not handled**
+   Interrupts returning to kernel don't clear CPUs buffers since the

+   a case when an NMI is generated in kernel after the exit-to-user path

+   kernel don't clear CPU buffers because:
+
+   1. It is rare to get an NMI after VERW, but before returning to userspace.
+   2. For an unprivileged user, there is no known way to make that NMI
+      less rare or target it.
+   3. It would take a large number of these precisely-timed NMIs to mount
+      an actual attack.  There's presumably not enough bandwidth.
+   4. The NMI in question occurs after a VERW, i.e. when user state is
+      restored and most interesting data is already scrubbed. Whats left
+      is only the data that NMI touches, and that may or may not be of
+      any interest.

+	  Binutils-2.38 and GCC-12.1.0 bumped the default ISA spec to the newer

+	  and Zifencei are supported in binutils from version 2.36 onwards.
+	  To make life easier, and avoid forcing toolchains that default to a

+	  For clang < 17 or GCC < 11.3.0, for which this is not possible or need

- *
- * This entry point can be used by 32-bit and 64-bit programs to perform
- * 32-bit system calls.  Instances of INT $0x80 can be found inline in

- *
- * This is considered a slow path.  It is not used by most libc
- * implementations on modern hardware except during process startup.

- * Arguments:
- * eax  system call number
- * ebx  arg1
- * ecx  arg2
- * edx  arg3
- * esi  arg4
- * edi  arg5
- * ebp  arg6
+ * int 0x80 is used by 32 bit mode as a system call entry. Normally idt entries

+/* In Clause 5 of IEEE Std 802-2014, two sublayers of the data link layer (DLL)
+ * of the Open Systems Interconnection basic reference model (OSI/RM) are
+ * described; the medium access control (MAC) and logical link control (LLC)
+ * sublayers. The MAC sublayer is the one facing the physical layer.
+ *
+ * In 8.2 of IEEE Std 802.1Q-2022, the Bridge architecture is described. A
+ * Bridge component comprises a MAC Relay Entity for interconnecting the Ports
+ * of the Bridge, at least two Ports, and higher layer entities with at least a
+ * Spanning Tree Protocol Entity included.
+ *
+ * Each Bridge Port also functions as an end station and shall provide the MAC
+ * Service to an LLC Entity. Each instance of the MAC Service is provided to a
+ * distinct LLC Entity that supports protocol identification, multiplexing, and
+ * demultiplexing, for protocol data unit (PDU) transmission and reception by
+ * one or more higher layer entities.
+ *
+ * It is described in 8.13.9 of IEEE Std 802.1Q-2022 that in a Bridge, the LLC
+ * Entity associated with each Bridge Port is modeled as being directly
+ * connected to the attached Local Area Network (LAN).
+ *
+ * On the switch with CPU port architecture, CPU port functions as Management
+ * Port, and the Management Port functionality is provided by software which
+ * functions as an end station. Software is connected to an IEEE 802 LAN that is
+ * wholly contained within the system that incorporates the Bridge. Software
+ * provides access to the LLC Entity associated with each Bridge Port by the
+ * value of the source port field on the special tag on the frame received by
+ * software.
+ *
+ * We call frames that carry control information to determine the active
+ * topology and current extent of each Virtual Local Area Network (VLAN), i.e.,
+ * spanning tree or Shortest Path Bridging (SPB) and Multiple VLAN Registration
+ * Protocol Data Units (MVRPDUs), and frames from other link constrained
+ * protocols, such as Extensible Authentication Protocol over LAN (EAPOL) and
+ * Link Layer Discovery Protocol (LLDP), link-local frames. They are not
+ * forwarded by a Bridge. Permanently configured entries in the filtering
+ * database (FDB) ensure that such frames are discarded by the Forwarding
+ * Process. In 8.6.3 of IEEE Std 802.1Q-2022, this is described in detail:
+ *
+ * Each of the reserved MAC addresses specified in Table 8-1
+ * (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]) shall be
+ * permanently configured in the FDB in C-VLAN components and ERs.
+ *
+ * Each of the reserved MAC addresses specified in Table 8-2
+ * (01-80-C2-00-00-[01,02,03,04,05,06,07,08,09,0A,0E]) shall be permanently
+ * configured in the FDB in S-VLAN components.
+ *
+ * Each of the reserved MAC addresses specified in Table 8-3
+ * (01-80-C2-00-00-[01,02,04,0E]) shall be permanently configured in the FDB in
+ * TPMR components.
+ *
+ * The FDB entries for reserved MAC addresses shall specify filtering for all
+ * Bridge Ports and all VIDs. Management shall not provide the capability to
+ * modify or remove entries for reserved MAC addresses.
+ *
+ * The addresses in Table 8-1, Table 8-2, and Table 8-3 determine the scope of
+ * propagation of PDUs within a Bridged Network, as follows:
+ *
+ *   The Nearest Bridge group address (01-80-C2-00-00-0E) is an address that no
+ *   conformant Two-Port MAC Relay (TPMR) component, Service VLAN (S-VLAN)
+ *   component, Customer VLAN (C-VLAN) component, or MAC Bridge can forward.
+ *   PDUs transmitted using this destination address, or any other addresses
+ *   that appear in Table 8-1, Table 8-2, and Table 8-3
+ *   (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]), can
+ *   therefore travel no further than those stations that can be reached via a
+ *   single individual LAN from the originating station.
+ *
+ *   The Nearest non-TPMR Bridge group address (01-80-C2-00-00-03), is an
+ *   address that no conformant S-VLAN component, C-VLAN component, or MAC
+ *   Bridge can forward; however, this address is relayed by a TPMR component.
+ *   PDUs using this destination address, or any of the other addresses that
+ *   appear in both Table 8-1 and Table 8-2 but not in Table 8-3
+ *   (01-80-C2-00-00-[00,03,05,06,07,08,09,0A,0B,0C,0D,0F]), will be relayed by
+ *   any TPMRs but will propagate no further than the nearest S-VLAN component,
+ *   C-VLAN component, or MAC Bridge.
+ *
+ *   The Nearest Customer Bridge group address (01-80-C2-00-00-00) is an address
+ *   that no conformant C-VLAN component, MAC Bridge can forward; however, it is
+ *   relayed by TPMR components and S-VLAN components. PDUs using this
+ *   destination address, or any of the other addresses that appear in Table 8-1
+ *   but not in either Table 8-2 or Table 8-3 (01-80-C2-00-00-[00,0B,0C,0D,0F]),
+ *   will be relayed by TPMR components and S-VLAN components but will propagate
+ *   no further than the nearest C-VLAN component or MAC Bridge.
+ *
+ * Because the LLC Entity associated with each Bridge Port is provided via CPU
+ * port, we must not filter these frames but forward them to CPU port.
+ *
+ * In a Bridge, the transmission Port is majorly decided by ingress and egress
+ * rules, FDB, and spanning tree Port State functions of the Forwarding Process.
+ * For link-local frames, only CPU port should be designated as destination port
+ * in the FDB, and the other functions of the Forwarding Process must not
+ * interfere with the decision of the transmission Port. We call this process
+ * trapping frames to CPU port.
+ *
+ * Therefore, on the switch with CPU port architecture, link-local frames must
+ * be trapped to CPU port, and certain link-local frames received by a Port of a
+ * Bridge comprising a TPMR component or an S-VLAN component must be excluded
+ * from it.
+ *
+ * A Bridge of the switch with CPU port architecture cannot comprise a Two-Port
+ * MAC Relay (TPMR) component as a TPMR component supports only a subset of the
+ * functionality of a MAC Bridge. A Bridge comprising two Ports (Management Port
+ * doesn't count) of this architecture will either function as a standard MAC
+ * Bridge or a standard VLAN Bridge.
+ *
+ * Therefore, a Bridge of this architecture can only comprise S-VLAN components,
+ * C-VLAN components, or MAC Bridge components. Since there's no TPMR component,
+ * we don't need to relay PDUs using the destination addresses specified on the
+ * Nearest non-TPMR section, and the proportion of the Nearest Customer Bridge
+ * section where they must be relayed by TPMR components.
+ *
+ * One option to trap link-local frames to CPU port is to add static FDB entries
+ * with CPU port designated as destination port. However, because that
+ * Independent VLAN Learning (IVL) is being used on every VID, each entry only
+ * applies to a single VLAN Identifier (VID). For a Bridge comprising a MAC
+ * Bridge component or a C-VLAN component, there would have to be 16 times 4096
+ * entries. This switch intellectual property can only hold a maximum of 2048
+ * entries. Using this option, there also isn't a mechanism to prevent
+ * link-local frames from being discarded when the spanning tree Port State of
+ * the reception Port is discarding.
+ *
+ * The remaining option is to utilise the BPC, RGAC1, RGAC2, RGAC3, and RGAC4
+ * registers. Whilst this applies to every VID, it doesn't contain all of the
+ * reserved MAC addresses without affecting the remaining Standard Group MAC
+ * Addresses. The REV_UN frame tag utilised using the RGAC4 register covers the
+ * remaining 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F] destination
+ * addresses. It also includes the 01-80-C2-00-00-22 to 01-80-C2-00-00-FF
+ * destination addresses which may be relayed by MAC Bridges or VLAN Bridges.
+ * The latter option provides better but not complete conformance.
+ *
+ * This switch intellectual property also does not provide a mechanism to trap
+ * link-local frames with specific destination addresses to CPU port by Bridge,
+ * to conform to the filtering rules for the distinct Bridge components.
+ *
+ * Therefore, regardless of the type of the Bridge component, link-local frames
+ * with these destination addresses will be trapped to CPU port:
+ *
+ * 01-80-C2-00-00-[00,01,02,03,0E]
+ *
+ * In a Bridge comprising a MAC Bridge component or a C-VLAN component:
+ *
+ *   Link-local frames with these destination addresses won't be trapped to CPU
+ *   port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ *   01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F]
+ *
+ * In a Bridge comprising an S-VLAN component:
+ *
+ *   Link-local frames with these destination addresses will be trapped to CPU
+ *   port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ *   01-80-C2-00-00-00
+ *
+ *   Link-local frames with these destination addresses won't be trapped to CPU
+ *   port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ *   01-80-C2-00-00-[04,05,06,07,08,09,0A]
+ *
+ * To trap link-local frames to CPU port as conformant as this switch
+ * intellectual property can allow, link-local frames are made to be regarded as
+ * Bridge Protocol Data Units (BPDUs). This is because this switch intellectual
+ * property only lets the frames regarded as BPDUs bypass the spanning tree Port
+ * State function of the Forwarding Process.
+ *
+ * The only remaining interference is the ingress rules. When the reception Port
+ * has no PVID assigned on software, VLAN-untagged frames won't be allowed in.
+ * There doesn't seem to be a mechanism on the switch intellectual property to
+ * have link-local frames bypass this function of the Forwarding Process.

- * Description:
- * The mdio bus will be allocated in case of a phy transceiver is on board;
- * it will be NULL if the fixed-link is configured.
- * If there is the "snps,dwmac-mdio" sub-node the mdio will be allocated

- *	-------------------------------
- *	phy-handle	|     Y
- *	-------------------------------

- *	fixed-link	|
- *	-------------------------------
+ * stmmac_of_get_mdio() - Gets the MDIO bus from the devicetree.
+ * @np: devicetree node
+ *
+ * The MDIO bus will be searched for in the following ways:
+ * 1. The compatible is "snps,dwc-qos-ethernet-4.10" && a "mdio" named
+ *    child node exists
+ * 2. A child node with the "snps,dwmac-mdio" compatible is present

+	  KMSAN, and other memory debug facilities, increase the size of
+	  'struct page' to contain extra metadata. This collides with
+	  the NVDIMM capability to store a potentially
+	  larger-than-"System RAM" size 'struct page' array in a
+	  reservation of persistent memory rather than limited /
+	  precious DRAM. However, that reservation needs to persist for
+	  the life of the given NVDIMM namespace. If you are using KMSAN
+	  to debug an issue unrelated to NVDIMMs or DAX then say N to this
+	  option. Otherwise, say Y but understand that any namespaces
+	  (with the page array stored pmem) created with this build of
+	  the kernel will permanently reserve and strand excess
+	  capacity compared to the CONFIG_KMSAN=n case.
+
+	  Select N if unsure.

+	 *
+	 * Description:
+	 * When the PWM FIFO is empty, a new value programmed to the PWM Sample
+	 * register (PWM_PWMSAR) will be directly applied even if the current
+	 * timer period has not expired.
+	 *
+	 * If the new SAMPLE value programmed in the PWM_PWMSAR register is
+	 * less than the previous value, and the PWM counter register
+	 * (PWM_PWMCNR) that contains the current COUNT value is greater than
+	 * the new programmed SAMPLE value, the current period will not flip
+	 * the level. This may result in an output pulse with a duty cycle of
+	 * 100%.
+	 *
+	 * Consider a change from
+	 *     ________
+	 *    /        \______/
+	 *    ^      *        ^
+	 * to
+	 *     ____
+	 *    /    \__________/
+	 *    ^               ^
+	 * At the time marked by *, the new write value will be directly applied
+	 * to SAR even the current period is not over if FIFO is empty.
+	 *
+	 *     ________        ____________________
+	 *    /        \______/                    \__________/

+	 *
+	 * That is the output is active for a whole period.
+	 *
+	 * Workaround:
+	 * Check new SAR less than old SAR and current counter is in errata
+	 * windows, write extra old SAR into FIFO and new SAR will effect at
+	 * next period.
+	 *
+	 * Sometime period is quite long, such as over 1 second. If add old SAR
+	 * into FIFO unconditional, new SAR have to wait for next period. It
+	 * may be too long.
+	 *
+	 * Turn off the interrupt to ensure that not IRQ and schedule happen
+	 * during above operations. If any irq and schedule happen, counter
+	 * in PWM will be out of data and take wrong action.
+	 *
+	 * Add a safety margin 1.5us because it needs some time to complete
+	 * IO write.
+	 *
+	 * Use writel_relaxed() to minimize the interval between two writes to

+ * When we leave the debug trap handler we need to reset the keyboard status

+ *
+ * The path to deliver the reset is somewhat circuitous.

+ * To deliver the reset we register an input handler, reset the keyboard and
+ * then deregister the input handler. However, to get this done right, we do
+ * have to carefully manage the calling context because we can only register
+ * input handlers from task context.
+ *
+ * In particular we need to trigger the action from the debug trap handler with
+ * all its NMI and/or NMI-like oddities. To solve this the kgdboc trap exit code
+ * (the "post_exception" callback) uses irq_work_queue(), which is NMI-safe, to
+ * schedule a callback from a hardirq context. From there we have to defer the
+ * work again, this time using schedule_work(), to get a callback using the

- *
- * Issue a %DWC3_DEPCMD_DEPSTARTCFG command to @dep. After the command's
- * completion, it will set Transfer Resource for all available endpoints.
- *
- * The assignment of transfer resources cannot perfectly follow the data book
- * due to the fact that the controller driver does not have all knowledge of the
- * configuration in advance. It is given this information piecemeal by the
- * composite gadget framework after every SET_CONFIGURATION and
- * SET_INTERFACE. Trying to follow the databook programming model in this
- * scenario can cause errors. For two reasons:
- *
- * 1) The databook says to do %DWC3_DEPCMD_DEPSTARTCFG for every
- * %USB_REQ_SET_CONFIGURATION and %USB_REQ_SET_INTERFACE (8.1.5). This is
- * incorrect in the scenario of multiple interfaces.
- *
- * 2) The databook does not mention doing more %DWC3_DEPCMD_DEPXFERCFG for new
- * endpoint on alt setting (8.1.6).
- *
- * The following simplified method is used instead:
+ * dwc3_gadget_start_config - reset endpoint resources
+ * @dwc: pointer to the DWC3 context
+ * @resource_index: DEPSTARTCFG.XferRscIdx value (must be 0 or 2)
  *
- * All hardware endpoints can be assigned a transfer resource and this setting
- * will stay persistent until either a core reset or hibernation. So whenever we
- * do a %DWC3_DEPCMD_DEPSTARTCFG(0) we can go ahead and do
- * %DWC3_DEPCMD_DEPXFERCFG for every hardware endpoint as well. We are
- * guaranteed that there are as many transfer resources as endpoints.
+ * Set resource_index=0 to reset all endpoints' resources allocation. Do this as
+ * part of the power-on/soft-reset initialization.
  *
- * This function is called for each endpoint when it is being enabled but is
- * triggered only when called for EP0-out, which always happens first, and which
- * should only happen in one of the above conditions.
+ * Set resource_index=2 to reset only non-control endpoints' resources. Do this
+ * on receiving the SET_CONFIGURATION request or hibernation resume.

+ * As we are scanning the page cache for data, we don't need to reimplement the
+ * wheel - mapping_seek_hole_data() does exactly what we need to identify the
+ * start and end of data ranges correctly even for sub-folio block sizes. This

+ * don't have to care about variable size folios, nor where the start or end of
+ * the data range lies within a folio, if they lie within the same folio or even
+ * if there are multiple discontiguous data ranges within the folio.
+ *
+ * It should be noted that mapping_seek_hole_data() is not aware of EOF, and so
+ * can return data ranges that exist in the cache beyond EOF. e.g. a page fault
+ * spanning EOF will initialise the post-EOF data to zeroes and mark it up to
+ * date. A write page fault can then mark it dirty. If we then fail a write()
+ * beyond EOF into that up to date cached range, we allocate a delalloc block
+ * beyond EOF and then have to punch it out. Because the range is up to date,
+ * mapping_seek_hole_data() will return it, and we will skip the punch because
+ * the folio is dirty. THis is incorrect - we always need to punch out delalloc
+ * beyond EOF in this case as writeback will never write back and covert that
+ * delalloc block beyond EOF. Hence we limit the cached data scan range to EOF,
+ * resulting in always punching out the range from the EOF to the end of the
+ * range the iomap spans.
+ *
+ * Intervals are of the form [start_byte, end_byte) (i.e. open ended) because it
+ * matches the intervals returned by mapping_seek_hole_data(). i.e. SEEK_DATA
+ * returns the start of a data range (start_byte), and SEEK_HOLE(start_byte)
+ * returns the end of the data range (data_end). Using closed intervals would

+ * DOC: Lockless queue stopping / waking helpers.
+ *
+ * The netif_txq_maybe_stop() and __netif_txq_completed_wake()
+ * macros are designed to safely implement stopping
+ * and waking netdev queues without full lock protection.
+ *
+ * We assume that there can be no concurrent stop attempts and no concurrent
+ * wake attempts. The try-stop should happen from the xmit handler,
+ * while wake up should be triggered from NAPI poll context.
+ * The two may run concurrently (single producer, single consumer).
+ *
+ * The try-stop side is expected to run from the xmit handler and therefore
+ * it does not reschedule Tx (netif_tx_start_queue() instead of
+ * netif_tx_wake_queue()). Uses of the ``stop`` macros outside of the xmit
+ * handler may lead to xmit queue being enabled but not run.
+ * The waking side does not have similar context restrictions.
+ *
+ * The macros guarantee that rings will not remain stopped if there's
+ * space available, but they do *not* prevent false wake ups when
+ * the ring is full! Drivers should check for ring full at the start
+ * for the xmit handler.
+ *
+ * All descriptor ring indexes (and other relevant shared state) must
+ * be updated before invoking the macros.

+ * assembly instructions (see backtrack_insns() for exact instruction handling
+ * logic). This backtracking relies on recorded jmp_history and is able to
+ * traverse entire chain of parent states. This process ends only when all the
+ * necessary registers/slots and their transitive dependencies are marked as
+ * precise.
+ *
+ * One important and subtle aspect is that precise marks *do not matter* in
+ * the currently verified state (current state). It is important to understand
+ * why this is the case.
+ *
+ * First, note that current state is the state that is not yet "checkpointed",
+ * i.e., it is not yet put into env->explored_states, and it has no children
+ * states as well. It's ephemeral, and can end up either a) being discarded if
+ * compatible explored state is found at some point or BPF_EXIT instruction is
+ * reached or b) checkpointed and put into env->explored_states, branching out
+ * into one or more children states.
+ *
+ * In the former case, precise markings in current state are completely
+ * ignored by state comparison code (see regsafe() for details). Only
+ * checkpointed ("old") state precise markings are important, and if old
+ * state's register/slot is precise, regsafe() assumes current state's
+ * register/slot as precise and checks value ranges exactly and precisely. If
+ * states turn out to be compatible, current state's necessary precise
+ * markings and any required parent states' precise markings are enforced
+ * after the fact with propagate_precision() logic, after the fact. But it's
+ * important to realize that in this case, even after marking current state
+ * registers/slots as precise, we immediately discard current state. So what
+ * actually matters is any of the precise markings propagated into current
+ * state's parent states, which are always checkpointed (due to b) case above).
+ * As such, for scenario a) it doesn't matter if current state has precise
+ * markings set or not.
+ *
+ * Now, for the scenario b), checkpointing and forking into child(ren)
+ * state(s). Note that before current state gets to checkpointing step, any
+ * processed instruction always assumes precise SCALAR register/slot
+ * knowledge: if precise value or range is useful to prune jump branch, BPF
+ * verifier takes this opportunity enthusiastically. Similarly, when
+ * register's value is used to calculate offset or memory address, exact
+ * knowledge of SCALAR range is assumed, checked, and enforced. So, similar to
+ * what we mentioned above about state comparison ignoring precise markings
+ * during state comparison, BPF verifier ignores and also assumes precise
+ * markings *at will* during instruction verification process. But as verifier
+ * assumes precision, it also propagates any precision dependencies across
+ * parent states, which are not yet finalized, so can be further restricted
+ * based on new knowledge gained from restrictions enforced by their children
+ * states. This is so that once those parent states are finalized, i.e., when
+ * they have no more active children state, state comparison logic in
+ * is_state_visited() would enforce strict and precise SCALAR ranges, if
+ * required for correctness.
+ *
+ * To build a bit more intuition, note also that once a state is checkpointed,
+ * the path we took to get to that state is not important. This is crucial
+ * property for state pruning. When state is checkpointed and finalized at
+ * some instruction index, it can be correctly and safely used to "short
+ * circuit" any *compatible* state that reaches exactly the same instruction
+ * index. I.e., if we jumped to that instruction from a completely different
+ * code path than original finalized state was derived from, it doesn't
+ * matter, current state can be discarded because from that instruction
+ * forward having a compatible state will ensure we will safely reach the
+ * exit. States describe preconditions for further exploration, but completely
+ * forget the history of how we got here.
+ *
+ * This also means that even if we needed precise SCALAR range to get to
+ * finalized state, but from that point forward *that same* SCALAR register is
+ * never used in a precise context (i.e., it's precise value is not needed for
+ * correctness), it's correct and safe to mark such register as "imprecise"
+ * (i.e., precise marking set to false). This is what we rely on when we do
+ * not set precise marking in current state. If no child state requires
+ * precision for any given SCALAR register, it's safe to dictate that it can
+ * be imprecise. If any child state does require this register to be precise,
+ * we'll mark it precise later retroactively during precise markings
+ * propagation from child state to parent states.
+ *
+ * Skipping precise marking setting in current state is a mild version of
+ * relying on the above observation. But we can utilize this property even
+ * more aggressively by proactively forgetting any precise marking in the
+ * current state (which we inherited from the parent state), right before we
+ * checkpoint it and branch off into new child state. This is done by
+ * mark_all_scalars_imprecise() to hopefully get more permissive and generic
+ * finalized states which help in short circuiting more future states.

-	 *
-	 * One perfect invariant is that number of allocated vectors for

-	 *
-	 * 1) suppose there are two nodes: A and B
-	 * 	ncpu(X) is CPU count of node X
-	 * 	vecs(X) is the vector count allocated to node X via this
-	 * 	algorithm
-	 *
-	 * 	ncpu(A) <= ncpu(B)
-	 * 	ncpu(A) + ncpu(B) = N
-	 * 	vecs(A) + vecs(B) = V
-	 *
-	 * 	vecs(A) = max(1, round_down(V * ncpu(A) / N))
-	 * 	vecs(B) = V - vecs(A)
-	 *
-	 * 	both N and V are integer, and 2 <= V <= N, suppose
-	 * 	V = N - delta, and 0 <= delta <= N - 2
-	 *
-	 * 2) obviously vecs(A) <= ncpu(A) because:
-	 *
-	 * 	if vecs(A) is 1, then vecs(A) <= ncpu(A) given
-	 * 	ncpu(A) >= 1
-	 *
-	 * 	otherwise,
-	 * 		vecs(A) <= V * ncpu(A) / N <= ncpu(A), given V <= N
-	 *
-	 * 3) prove how vecs(B) <= ncpu(B):
-	 *
-	 * 	if round_down(V * ncpu(A) / N) == 0, vecs(B) won't be
-	 * 	over-allocated, so vecs(B) <= ncpu(B),
-	 *
-	 * 	otherwise:
-	 *
-	 * 	vecs(A) =
-	 * 		round_down(V * ncpu(A) / N) =
-	 * 		round_down((N - delta) * ncpu(A) / N) =
-	 * 		round_down((N * ncpu(A) - delta * ncpu(A)) / N)	 >=
-	 * 		round_down((N * ncpu(A) - delta * N) / N)	 =
-	 * 		cpu(A) - delta
-	 *
-	 * 	then:
-	 *
-	 * 	vecs(A) - V >= ncpu(A) - delta - V
-	 * 	=>
-	 * 	V - vecs(A) <= V + delta - ncpu(A)
-	 * 	=>
-	 * 	vecs(B) <= N - ncpu(A)
-	 * 	=>
-	 * 	vecs(B) <= cpu(B)

+	 * 	G = N - delta, and 0 <= delta <= N - 2
+	 *
+	 * 2) obviously grps(A) <= ncpu(A) because:
+	 *
+	 * 	if grps(A) is 1, then grps(A) <= ncpu(A) given
+	 * 	ncpu(A) >= 1
+	 *
+	 * 	otherwise,
+	 * 		grps(A) <= G * ncpu(A) / N <= ncpu(A), given G <= N
+	 *
+	 * 3) prove how grps(B) <= ncpu(B):
+	 *
+	 * 	if round_down(G * ncpu(A) / N) == 0, vecs(B) won't be
+	 * 	over-allocated, so grps(B) <= ncpu(B),
+	 *
+	 * 	otherwise:
+	 *
+	 * 	grps(A) =
+	 * 		round_down(G * ncpu(A) / N) =
+	 * 		round_down((N - delta) * ncpu(A) / N) =

-	 *
-	 * or to b4., which, preceded by a3., means we already traversed one or
-	 * more existing intervals entirely, from the right.
-	 *
-	 * For a new, rightmost pair of elements, we'll hit cases b3. and b2.,
-	 * in that order.
-	 *
-	 * The flag is also cleared in two special cases:

-	 * b5. |__ _ _!|<_ _ _   (insert start right before existing end)

-	 *

-	 * overlapping is possible.
-	 *
-	 * Another special case comes from the fact that start elements matching
-	 * an already existing start element are allowed: insertion is not
-	 * performed but we return -EEXIST in that case, and the error will be
-	 * cleared by the caller if NLM_F_EXCL is not present in the request.
-	 * This way, request for insertion of an exact overlap isn't reported as
-	 * error to userspace if not desired.
-	 *
-	 * However, if the existing start matches a pre-existing start, but the
-	 * end element doesn't match the corresponding pre-existing end element,
-	 * we need to report a partial overlap. This is a local condition that
-	 * can be noticed without need for a tracking flag, by checking for a
-	 * local duplicated end for a corresponding start, from left and right,
-	 * separately.

-   Comparing to general packet classification problem,
-   RSVP needs only several relatively simple rules:
-
-   * (dst, protocol) are always specified,
-     so that we are able to hash them.
-   * src may be exact, or may be wildcard, so that
-     we can keep a hash table plus one wildcard entry.
-   * source port (or flow label) is important only if src is given.
-
-   IMPLEMENTATION.
-
-   We use a two level hash table: The top level is keyed by
-   destination address and protocol ID, every bucket contains a list
-   of "rsvp sessions", identified by destination address, protocol and
-   DPI(="Destination Port ID"): triple (key, mask, offset).
-
-   Every bucket has a smaller hash table keyed by source address
-   (cf. RSVP flowspec) and one wildcard entry for wildcard reservations.
-   Every bucket is again a list of "RSVP flows", selected by
-   source address and SPI(="Source Port ID" here rather than
-   "security parameter index"): triple (key, mask, offset).
-
-
-   NOTE 1. All the packets with IPv6 extension headers (but AH and ESP)
-   and all fragmented packets go to the best-effort traffic class.
-
-
-   NOTE 2. Two "port id"'s seems to be redundant, rfc2207 requires
-   only one "Generalized Port Identifier". So that for classic
-   ah, esp (and udp,tcp) both *pi should coincide or one of them
-   should be wildcard.
-
-   At first sight, this redundancy is just a waste of CPU
-   resources. But DPI and SPI add the possibility to assign different
-   priorities to GPIs. Look also at note 4 about tunnels below.
-
-
-   NOTE 3. One complication is the case of tunneled packets.
-   We implement it as following: if the first lookup
-   matches a special session with "tunnelhdr" value not zero,
-   flowid doesn't contain the true flow ID, but the tunnel ID (1...255).
-   In this case, we pull tunnelhdr bytes and restart lookup
-   with tunnel ID added to the list of keys. Simple and stupid 8)8)
-   It's enough for PIMREG and IPIP.
-
-
-   NOTE 4. Two GPIs make it possible to parse even GRE packets.
-   F.e. DPI can select ETH_P_IP (and necessary flags to make
-   tunnelhdr correct) in GRE protocol field and SPI matches
-   GRE key. Is it not nice? 8)8)
-
-
-   Well, as result, despite its simplicity, we get a pretty
-   powerful classification engine.  */

- * The ATM queuing discipline provides a framework for invoking classifiers
- * (aka "filters"), which in turn select classes of this queuing discipline.
- * Each class maps the flow(s) it is handling to a given VC. Multiple classes
- * may share the same VC.
- *
- * When creating a class, VCs are specified by passing the number of the open
- * socket descriptor by which the calling process references the VC. The kernel
- * keeps the VC open at least until all classes using it are removed.
- *
- * In this file, most functions are named atm_tc_* to avoid confusion with all
- * the atm_* in net/atm. This naming convention differs from what's used in the
- * rest of net/sched.
- *
- * Known bugs:
- *  - sometimes messes up the IP stack
- *  - any manipulations besides the few operations described in the README, are
- *    untested and likely to crash the system
- *  - should lock the flow while there is data in the queue (?)

-
-	-----------------------------------------------------------------------
-
-	Algorithm skeleton was taken from NS simulator cbq.cc.
-	If someone wants to check this code against the LBL version,
-	he should take into account that ONLY the skeleton was borrowed,
-	the implementation is different. Particularly:
-
-	--- The WRR algorithm is different. Our version looks more
-	reasonable (I hope) and works when quanta are allowed to be
-	less than MTU, which is always the case when real time classes
-	have small rates. Note, that the statement of [3] is
-	incomplete, delay may actually be estimated even if class
-	per-round allotment is less than MTU. Namely, if per-round
-	allotment is W*r_i, and r_1+...+r_k = r < 1
-
-	delay_i <= ([MTU/(W*r_i)]*W*r + W*r + k*MTU)/B
-
-	In the worst case we have IntServ estimate with D = W*r+k*MTU
-	and C = MTU*r. The proof (if correct at all) is trivial.
-
-
-	--- It seems that cbq-2.0 is not very accurate. At least, I cannot
-	interpret some places, which look like wrong translations
-	from NS. Anyone is advised to find these differences
-	and explain to me, why I am wrong 8).
-
-	--- Linux has no EOI event, so that we cannot estimate true class
-	idle time. Workaround is to consider the next dequeue event
-	as sign that previous packet is finished. This is wrong because of
-	internal device queueing, but on a permanently loaded link it is true.
-	Moreover, combined with clock integrator, this scheme looks
-	very close to an ideal solution.  */

+Pipe mode
+---------
+Pipe mode is a problem for Intel PT and possibly other auxtrace users.
+It's not recommended to use a pipe as data output with Intel PT because
+of the following reason.
+
+Essentially the auxtrace buffers do not behave like the regular perf
+event buffers.  That is because the head and tail are updated by
+software, but in the auxtrace case the data is written by hardware.
+So the head and tail do not get updated as data is written.
+
+In the Intel PT case, the head and tail are updated only when the trace
+is disabled by software, for example:
+    - full-trace, system wide : when buffer passes watermark
+    - full-trace, not system-wide : when buffer passes watermark or
+                                    context switches
+    - snapshot mode : as above but also when a snapshot is made
+    - sample mode : as above but also when a sample is made
+
+That means finished-round ordering doesn't work.  An auxtrace buffer
+can turn up that has data that extends back in time, possibly to the
+very beginning of tracing.
+
+For a perf.data file, that problem is solved by going through the trace
+and queuing up the auxtrace buffers in advance.
+
+For pipe mode, the order of events and timestamps can presumably
+be messed up.
