I posted initial change that allows auditd to log BPF program
load/unload events, it's in here:

Thanks for the patch...but we probably should have talked a bit more before
undertaking this effort. We normally do not audit from user space what happens
in the kernel. Doing this can be racy and it keeps auditd from doing the one
job it has - which is to grab events and record them to disk and send them
out the realtime interface.
We tried to push pure AUDIT interface for BPF program notification,
but it was denied, the discussion is in here:

Hmm. The email I remember was here:
https://www.redhat.com/archives/linux-audit/2018-October/msg00053.html
and was only 2 emails long with no answer to my question. :-)
The outcome of the discussion was to use perf event interface
for BPF notification and use it in some deamon.. audit was our
first choice.
thoughts?
I'd like to understand what the basic problem is that needs to be solved.
