Pull selinux updates from Paul Moore:
 "A relatively small set of patches for SELinux this time, eight patches
  in total with really only one significant change.

  The highlights are:

   - Add support for proper labeling of memfd_secret anonymous inodes.

     This will allow LSMs that implement the anonymous inode hooks to
     apply security policy to memfd_secret() fds.

   - Various small improvements to memory management: fixed leaks, freed
     memory when needed, boundary checks.

   - Hardened the selinux_audit_data struct with __randomize_layout.

   - A minor documentation tweak to fix a formatting/style issue"
