Merge tag 'selinux-pr-20210629' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull SELinux updates from Paul Moore:

 - The slow_avc_audit() function is now non-blocking so we can remove
   the AVC_NONBLOCKING tricks; this also includes the 'flags' variant of
   avc_has_perm().

 - Use kmemdup() instead of kcalloc()+copy when copying parts of the
   SELinux policydb.

 - The InfiniBand device name is now passed by reference when possible
   in the SELinux code, removing a strncpy().

 - Minor cleanups including: constification of avtab function args,
   removal of useless LSM/XFRM function args, SELinux kdoc fixes, and
   removal of redundant assignments.
