Merge tag 'selinux-pr-20190702' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:
 "Like the audit pull request this is a little early due to some
  upcoming vacation plans and uncertain network access while I'm away.
  Also like the audit PR, the list of patches here is pretty minor, the
  highlights include:

   - Explicitly use __le variables to make sure "sparse" can verify
     proper byte endian handling.

   - Remove some BUG_ON()s that are no longer needed.

   - Allow zero-byte writes to the "keycreate" procfs attribute without
     requiring key:create to make it easier for userspace to reset the
     keycreate label.

   - Consistently log the "invalid_context" field as an untrusted string
     in the AUDIT_SELINUX_ERR audit records"
