reporting loginuid on AUDIT_USER message

Based on earlier discussion, we have a few options: 1. hack netlink to send loginuid along with credentials 2. Get the loginuid from the task struct by pid at audit_receive_msg (), and require the programs sending AUDIT_USER messages to make sure that the process does not exit until a reply has been received. 3. Have the user-space programs send loginuid (as received from /proc/$$/loginuid) in the actual AUDIT_USER message. Do we have a preference? (1) is the most invasive, and would require going through netdev, but seems the cleanest to me. On the other hand, we could just say we're going with (3) as a way to put off having to make a decision... thanks, -serge -- Serge Hallyn <serue(a)us.ibm.com&gt;
