Suggestions based on my experiences so far

I'd first like to say that I am a big fan of this auditing software, and it has made life good for me (I am currently working on a project where we are investigating system call behavior to see if any optimizations are possible). I know this project is still in its early stages, but I do have some suggestions: 1. I tried to do 'kill -HUP auditd' to get the daemon to re-read the configuration file (in order to make it write to a new log file in case the original got too big), but this did not work. As I understand it, this is should be the expected behavior for daemons. 2. The name of the process (or command) which invoked the system call is not logged (tsk->comm). I think it would not only be good to know exactly what invoked it, but to know if the process associated with a particular PID changes (if process P1 has PID N, invokes some system calls, exits, and then process P2 gets PID N, invokes other system calls, then P1 and P2 will be indistinguishable). 3. Maybe a way to set the log format would be helpful, so that you could include only the information you need and keep log sizes to a minimum. 4. Since we can trace both entries and exits, there should be a way to know what is an entry and what is an exit (I'm pretty sure you can't do this right now). Also, it would be good if you could somehow correlate entries and exits. Avishay Traeger
