Subject: [PATCH 0/3][RFC] x86: Catch stray non-kprobe breakpoints
Date: Sun, 27 Jan 2008 14:38:56 +0530	[thread overview]
Message-ID: <> (raw)


Non kprobe breakpoints in the kernel might lie inside the .kprobes.text section. Such breakpoints can easily be identified by in_kprobes_functions and can be caught early. These are problematic and a warning should be emitted to discourage them (in any rare case, if they actually occur).

For this, a check can route the trap handling of such breakpoints away from kprobe_handler (which ends up calling even more functions marked as __kprobes) from inside kprobe_exceptions_notify.

All comments/suggestions are welcome.

Thanks & Regards,
Abhishek Sagar
