It would be great to get a stacktrace on apparmor "events" - maybe add a tracepoint

Hi,
as just discussed it would be a great help to add a tracepoint(s) at intersting spots like the DENY message.
If that is a common place give it an argument for the message so people cna filter on it.
If these are different places add them as multiple tracepoints.

Then people could easily with perf do the tracing and get all they need (backtraces, but also much more if needed).

We all kind of agreed so this is mostly to track so I get a ping once you do something on it.
