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

Pull audit updates from Paul Moore:
 "This pull request is a bit early, but with some vacation time coming
  up I wanted to send this out now just in case the remote Internet Gods
  decide not to smile on me once the merge window opens. The patchset
  for v5.3 is pretty minor this time, the highlights include:

   - When the audit daemon is sent a signal, ensure we deliver
     information about the sender even when syscall auditing is not
     enabled/supported.

   - Add the ability to filter audit records based on network address
     family.

   - Tighten the audit field filtering restrictions on string based
     fields.

   - Cleanup the audit field filtering verification code.

   - Remove a few BUG() calls from the audit code"
