Subject: [PATCH] mac80211: fix ethtool stats for non-station interfaces
Date: Mon, 8 Jul 2013 10:46:31 +0200 [thread overview]
Message-ID: <1373273191-16251-1-git-send-email-johannes@sipsolutions.net> (raw)
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.
