Hi Linus,
A decent number of SELinux patches for v5.10, twenty two in total.
The highlights are listed below, but all of the patches pass our test
suite and merge cleanly against your tree. Please merge for v5.10.
- A number of changes to how the SELinux policy is loaded and managed
inside the kernel with the goal of improving the atomicity of a
SELinux policy load operation. These changes account for the bulk of
the diffstat as well as the patch count. A special thanks to everyone
who contributed patches and fixes for this work.
- Convert the SELinux policy read-write lock to RCU.
- A tracepoint was added for audited SELinux access control events;
this should help provide a more unified backtrace across kernel and
userspace.
- Allow the removal of security.selinux xattrs when a SELinux policy
is not loaded.
- Enable policy capabilities in SELinux policies created with the
scripts/selinux/mdp tool.
- Provide some "no sooner than" dates for the SELinux checkreqprot
sysfs deprecation.
Thanks,
-Paul
