Should be possible, but it requires a kernel patch to really be right. I think
the patch is landing in the RHEL5.3 kernel and 2.6.28. What it does is gives
2 event records on fork/clone.
I've been trying to use the audit subsystem to do this, but no
matter
which way I tried, so far I hadn't been successful.
I've tried these for task creation:
- auditctl -a entry,always -S fork -S vfork -S clone
This way I can't know the pid of the new process, just the
caller;
This rule should do it. That is what the kernel patch fixes. You would get 2
records now. This was fixed under, bz#461831
And this for task destruction:
- auditctl -a entry,always -S exit -S exit_group
Works most of the time, but doesn't catch "killall sshd"
(doesn't get the "sshd is dying" part).
Some tasks exit in a strange way. Have you tried stracing sshd to see how it
exits?
