Merge tag 'audit-pr-20211101' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit
Pull audit updates from Paul Moore:
"Add some additional audit logging to capture the openat2() syscall
open_how struct info.
Previous variations of the open()/openat() syscalls allowed audit
admins to inspect the syscall args to get the information contained in
the new open_how struct used in openat2()"
* tag 'audit-pr-20211101' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:
audit: return early if the filter rule has a lower priority
audit: add OPENAT2 record to list "how" info
audit: add support for the openat2 syscall
audit: replace magic audit syscall class numbers with macros
lsm_audit: avoid overloading the "key" audit field
audit: Convert to SPDX identifier
audit: rename struct node to struct audit_node to prevent future name collisions
