From: Christian Lamparter Date: Tue, 24 Aug 2010 17:22:42 +0000 (+0200) Subject: mac80211: fix rcu-unsafe pointer dereference X-Git-Tag: v2.6.37-rc1~147^2~584^2^2~41 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2c15a0cf27a74213a714cc7be31685b841f7c1ac;p=pandora-kernel.git mac80211: fix rcu-unsafe pointer dereference This patch fixes a potential crash (null-pointer de- reference) which was introduced in my previous patch: "mac80211: AMPDU rx reorder timeout timer" During a BA teardown, the pointer to the soon-to-be-gone tid_ampdu_rx element will be nullified. Therefore the release timer mechanism has to be careful not to accidentally access the item without any RCU protection. Signed-off-by: Christian Lamparter Signed-off-by: John W.
