Merge tag 'safesetid-6.0' of https://github.com/micah-morton/linux

Pull SafeSetID updates from Micah Morton:
 "This contains one commit that touches common kernel code, one that
  adds functionality internal to the SafeSetID LSM code, and a few other
  commits that only modify the SafeSetID LSM selftest.

  The commit that touches common kernel code simply adds an LSM hook in
  the setgroups() syscall that mirrors what is done for the existing LSM
  hooks in the setuid() and setgid() syscalls. This commit combined with
  the SafeSetID-specific one allow the LSM to filter setgroups() calls
  according to configured rule sets in the same way that is already done
  for setuid() and setgid()"
