Definitely is WRONG from my point of view. If the tracer goes away, then -9 should work. Principle of least surprise. I tend to believe that -9 should also override being traced as well. I can sort of understand that someone might think they can trace through a -9, but since that signal is never delivered to the process, nor can it be ignored, I can't understand why it matters. Sure, let the ptrace'r know that the process got a -9. - -- ] "Elmo went to the wrong fundraiser" - The Simpson | firewalls [ ] Michael Richardson, Xelerance Corporation, Ottawa, ON |net architect[ ] mcr@xelerance.com http://www.sandelman.ottawa.on.ca/mcr/ |device driver[ ] panic("Just another Debian GNU/Linux using, kernel hacking, security guy"); [ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) Comment: Finger me for keys iQCVAwUBQXb6sYqHRg3pndX9AQEC/AQAujSBVJh0Qel5I6fJkHTS6YWrCWk7XtQf i8tVsxrxmyE6baWvhfCm/QRZMozxxdQhRA9dIdPEa9/DMewnshAkMG+Ltg8n9q9p QJuKz/6XqbK7locR/48pp96X3y1/4+xdlvb5J276jOwG8wKkYdqlmqvuKD10pn8e aRPPq20vmBM= =/4b6 -----END PGP SIGNATURE----- ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
