[GIT PULL] AppArmor updates for 6.8

[GIT PULL] AppArmor updates for 6.8

[John Johansen]

Hi Linus,

Please pull the following apparmor for patches for the 6.8 merge
window.

This PR adds a single feature, switch the hash used to check policy
from sha1 to sha256

There are fixes for two memory leaks, and refcount bug and a potential
crash when a profile name is empty. Along with a couple minor code
cleanups.

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 this morning.

thanks
- john
