Merge tag 'audit-pr-20200601' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "Summary of the significant patches:

   - Record information about binds/unbinds to the audit multicast
     socket. This helps identify which processes have/had access to the
     information in the audit stream.

   - Cleanup and add some additional information to the netfilter
     configuration events collected by audit.

   - Fix some of the audit error handling code so we don't leak network
     namespace references"
