Merge tag 'audit-pr-20250926' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:

 - Proper audit support for multiple LSMs

   As the audit subsystem predated the work to enable multiple LSMs,
   some additional work was needed to support logging the different LSM
   labels for the subjects/tasks and objects on the system. Casey's
   patches add new auxillary records for subjects and objects that
   convey the additional labels.

 - Ensure fanotify audit events are always generated

   Generally speaking security relevant subsystems always generate audit
   events, unless explicitly ignored. However, up to this point fanotify
   events had been ignored by default, but starting with this pull
   request fanotify follows convention and generates audit events by
   default.

 - Replace an instance of strcpy() with strscpy()

 - Minor indentation, style, and comment fixes
