RE: listening to /dev/audit in a pthread program



(Ignore my comment about /dev/audit - I wasn't thinking, yes I call
audit_open)
Thanks

In fact I was wrong. In both cases the listener loop is in a secondary
thread (gotta read my own code more closely). The differntiator is where the
audit_open is called relative to the other threads.

So a bit more hacking based on your reply shows the real rule :-
The pid passed to audit_set_pid must be the pid that called audit_open not
the pid that's listening

Thanks agin. All working now

There isn't a /dev/audit in linux.org kernels.

The important detail is where the audit_open call is made. Netlink want to
send it to the same tid.
