Merge tag 'audit-pr-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "Another relatively small pull request for audit, nine patches total.

  The only real new bit of functionality is the patch from Richard which
  adds the ability to filter records based on the filesystem type.

  The remainder are bug fixes and cleanups; the bug fix highlights
  include:

   - ensuring that we properly audit init/PID-1 (me)

   - allowing the audit daemon to shutdown the kernel/auditd connection
     cleanly by setting the audit PID to zero (Steve)"

* tag 'audit-pr-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:
  audit: filter PATH records keyed on filesystem magic
  Audit: remove unused audit_log_secctx function
  audit: Allow auditd to set pid to 0 to end auditing
  audit: Add new syscalls to the perm=w filter
  audit: use audit_set_enabled() in audit_enable()
  audit: convert audit_ever_enabled to a boolean
  audit: don't use simple_strtol() anymore
  audit: initialize the audit subsystem as early as possible
  audit: ensure that 'audit=1' actually enables audit for PID 1
