Subject: [Bridge] [Regression][3.12] bridge: fix NULL pointer deref of br_port_get_rcu
Date: Tue, 03 Dec 2013 14:12:20 -0500	[thread overview]
Message-ID: <529E2D14.9000303@canonical.com> (raw)

Hi Hong,

A kernel bug was opened against Ubuntu [0].  After a kernel bisect, it
was found that reverting the following commit resolved
this bug:

commit 716ec052d2280d511e10e90ad54a86f5b5d4dcc2
Author: Hong Zhiguo <zhiguohong@tencent.com>
Date:   Sat Sep 14 22:42:28 2013 +0800

    bridge: fix NULL pointer deref of br_port_get_rcu


The regression was introduced as of v3.12-rc2 and has made it into some
of the stable trees(3.10 and 3.11).

I was thinking of requesting a revert for this commit, but I wanted to
get your feedback first, since you are the patch author.


Thanks,

Joe
