Merge tag 'audit-pr-20180814' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit patches from Paul Moore:
 "Twelve audit patches for v4.19 and they run the full gamut from fixes
  to features.

  Notable changes include the ability to use the "exe" audit filter
  field in a wider variety of filter types, a fix for our comparison of
  GID/EGID in audit filter rules, better association of related audit
  records (connecting related audit records together into one audit
  event), and a fix for a potential use-after-free in audit_add_watch().

  All the patches pass the audit-testsuite and merge cleanly on your
  current master branch"
