[GIT PULL] audit/audit-pr-20250926

[Paul Moore]

Linus,

Here are the audit patches for the upcoming Linux v6.18 merge window:

- 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
