Subject: [GIT PULL] AppArmor updates for 6.7
Hi Linus,
Please pull the following apparmor for patches for the 6.7 merge
window.
This PR adds initial support for mediating io_uring and userns
creation. Adds a new restriction that tightens the use of
change_profile, and a couple of optimizations to reduce performance
bottle necks that have been found when retrieving the current task's
secid and allocating work buffers.
The majority of the patch set continues cleaning up and simplifying
the code (fixing comments, removing now dead functions, and macros
etc). Finally there are 4 bug fixes, with the regression fix having
had a couple months of testing.
These patches have been in linux-next and been tested while in there,
and have also had a merge and regression test against your current
tree as of a day ago.
thanks
- john
