From 1f6fc43e621167492ed4b7f3b4269c584c3d6ccc Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Thu, 2 Aug 2012 18:41:48 +0100 Subject: cfg80211: process pending events when unregistering net device libertas currently calls cfg80211_disconnected() when it is being brought down. This causes an event to be allocated, but since the wdev is already removed from the rdev by the time that the event processing work executes, the event is never processed or freed. http://article.gmane.org/gmane.linux.kernel.wireless.general/95666 Fix this leak, and other possible situations, by processing the event queue when a device is being unregistered. Thanks to Johannes Berg for the suggestion. Signed-off-by: Daniel Drake Cc: stable@vger.kernel.org Reviewed-by: Johannes Berg Signed-off-by: John W.
