The next patch series will also contain a new kind of audit rule to specifically identify the origin of the policy that created this denied event, which should make more sense.Generally speaking audit only wants to support a small number of message types dedicated to a specific LSM. If you're aware of additional message types that you plan to propose in a future patchset, it's probably a time to discuss those now.The only other audit record type I'm thinking about would be one dedicated to "potentially denied access", something similar to SELinux's permissive mode.
In this case the "audit way" to handle this would be to add a "permissive=[0|1]" field, or similar, to the AUDIT_LANDLOCK_ACCESS message. If this is something you are definitely going to add to Landlock, I might suggest adding the "permissive=" field now so it is present from the start. -- paul-moore.com
