Hi,
This is the 3rd version of bugfix series for kprobes on arm.
This series fixes 4 different issues which I found.
- Fix to use smp_processor_id() after disabling preemption.
- Prohibit probing on optimized_callback() for avoiding
recursive probe.
- Prohibit kprobes on do_undefinstr() by same reason.
- Prohibit kprobes on get_user() by same reason.
>From v2, I included another 2 bugfixes (1/4 and 2/4)
which are not merged yet, and added "Cc: stable@xxxxxxxxxxxxxxx",
since there are obvious bugs.
Thanks,
