| * PR10016: Purge stap of all pgrp and system() usageJosh Stone2009-04-011-73/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We hereby no longer try to manipulate process groups in any way. We don't set a private process group, and we never kill() our entire group either. Instead of using system(), we now have a stap_system() which saves the child PID, so when we get a terminating signal we can pass it along to the child. Signals sent through the TTY have always worked, since the TTY sends it to the entire pgrp. However, if we're running as part of a wrapper script or GUI, which may not have a separate process group for stap, we still would like to allow "kill -TERM $STAPPID" to terminate stap nicely. There's still a short window of failure in the time that staprun is active, because we can't kill a setuid process from a user process. Once staprun drops privileges and execs to stapio though, everything should work fine.
