Message-Id: <1376476624-10011-3-git-send-email-luis.henriques@canonical.com> Date: Wed, 14 Aug 2013 11:35:51 +0100 From: Luis Henriques <luis.henriques@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Johannes Berg <johannes@...solutions.net>, Luis Henriques <luis.henriques@...onical.com> Subject: [PATCH 02/75] mac80211: fix ethtool stats for non-station interfaces 3.5.7.19 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Johannes Berg <johannes@...solutions.net> commit e13bae4f807401729b3f27c7e882a96b8b292809 upstream. As reported in https://bugzilla.kernel.org/show_bug.cgi?id=60514, the station loop never initialises 'sinfo' and therefore adds up a stack values, leaking stack information (the number of times it adds values is easily obtained another way.) Fix this by initialising the sinfo for each station to add.
