SELinux — The Linux Kernel 6.14.0-gnu-rt3-parabola1-1-rt documentation

# SELinux

If you want to use SELinux, chances are you will want to use the distro-provided policies, or install the latest reference policy release from

> https://github.com/SELinuxProject/refpolicy

However, if you want to install a dummy policy for testing, you can do using `mdp` provided under scripts/selinux. Note that this requires the selinux userspace to be installed - in particular you will need checkpolicy to compile a kernel, and setfiles and fixfiles to label the filesystem.

> 1. Compile the kernel with selinux enabled.

> 2. Type `make` to compile `mdp`.

> 3. Make sure that you are not running with SELinux enabled and a real policy. If you are, reboot with selinux disabled before continuing.

> 4. Run install_policy.sh:

>        cd scripts/selinux
>        sh install_policy.sh

Step 4 will create a new dummy policy valid for your kernel, with a single selinux user, role, and type. It will compile the policy, will set your `SELINUXTYPE` to `dummy` in `/etc/selinux/config`, install the compiled policy as `dummy`, and relabel your filesystem.
