Subject: [PATCH v2 0/6] uprobes: fix fork() with the pending ret-probe(s)
Date: Fri, 18 Oct 2013 17:49:47 +0200 [thread overview]
Message-ID: <20131018154947.GA15002@redhat.com> (raw)
Hello.
This series fixes the serious bug reported by Martin and David
and cc's stable. See the changelog in 5/6.
The changes are minimal, I am sending v2 just in case before I
ask to pull.
v2:
2/6: whitespace fix
4/6: update the changelog to explain why we do not cleanup
the child's stack instead
5/6: check area != NULL before dup xol_area
1-5: add the acks from Srikar. I assume he agrees with 6/6
as well.
Oleg.
