Merge branch 'stable-4.13' of git://git.infradead.org/users/pcmoore/audit

Browse source 
Pull audit updates from Paul Moore:
 "Things are relatively quiet on the audit front for v4.13, just five
  patches for a total diffstat of 102 lines.

  There are two patches from Richard to consistently record the POSIX
  capabilities and add the ambient capability information as well.

  I also chipped in two patches to fix a race condition with the auditd
  tracking code and ensure we don't skip sending any records to the
  audit multicast group.

  Finally a single style fix that I accepted because I must have been in
  a good mood that day.

  Everything passes our test suite, and should be relatively harmless,
  please merge for v4.13"

* 'stable-4.13' of git://git.infradead.org/users/pcmoore/audit:
  audit: make sure we never skip the multicast broadcast
  audit: fix a race condition with the auditd tracking code
  audit: style fix
  audit: add ambient capabilities to CAPSET and BPRM_FCAPS records
  audit: unswing cap_* fields in PATH records
