Subject: [BUGFIX PATCH v3 0/4] arm: kprobes: Fix to prohibit probing on unsafe functions
Date: Fri,  4 May 2018 13:14:31 +0900	[thread overview]
Message-ID: <152540727123.29650.13679359124038587629.stgit@devbox> (raw)

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@vger.kernel.org",
since there are obvious bugs.

Thanks,

---
