Pull AppArmor updates from John Johansen:
 "The biggest functional change is Jann Horn's fix for how aparmor is
  doing stale cred updates after a policy replacement.

     apparmor: fix cred UAF caused by begin_current_label_crit_section()

  It moves the update to be done during task_work at the end of the
  syscall.

  One major feature is allowing policy to be compressed in userspace
  instead of after the fact (in kernel) if we need to hold onto it for
  CRIU/introspection.

  The other major change is to do with network mediation. It is a lot of
  code churn but does not do any functional changes to mediation. It
  moves the code around, and refactors it to use newer patterns for
  consistency, and in preparation for some improvements in mediation in
  a future patchset.

  Features:
   - support loading compressed policies
   - add audit mode to provide a mechanism to silence complain messages
   - refactor network mediation to use new patterns, and prepare to for
     extended inet mediation (no functional change)

  Cleanups:
   - switch website link to https
   - make include headers self-contained, and fix circular include
   - constify aa_label, aa_dfa, aa_profile, and aa_perms paraneters
   - mark static tables and structs as read only
   - drop use of _confined variant for iteration
   - refactory mount to use check_perms
   - refactor network mediation code to be together
   - refactor xattr attachment, to take the file path
   - optimize current_label_crit_section()
   - leverage audit_log_n_untrustedstring() when possible

  Bug Fixes:
   - initialized policy lists heads before fail path
   - fix deadlock in complain-mode change_hat
   - auditing of mount binary data
   - fix error debug output in fn_label_build
   - fix race condition in label replacement
   - fix unconfined user namespace restriction forced stack
   - fix error handling for copy_from_user in policy_update
   - fix out-of-bounds write when null terminating a label vec
   - fix integer overflow in verify_tags() bounds check
   - fix cred UAF caused by begin_current_label_crit_section()
   - use SEND_SIG_NOINFO instead of NULL in aa_audit()"
