From 0e0a228398cc967c922759be36c69d32e4f62701 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Fri, 26 Feb 2010 08:13:41 +0200 Subject: [PATCH] mac80211: fix direct probe loop on ieee80211_work_purge If authentication has already been performed when the WLAN interface is stopped, (sometimes) the ieee80211_work_purge would corrupt some ieee80211_work-structures. The outcome is this (cleaned up): [ 2252.398681] WARNING: at net/mac80211/work.c:995 ieee80211_work_purge [ 2252.466430] Backtrace: [ 2252.529266] (ieee80211_work_purge+0x0/0xcc [mac80211]) [ 2252.546875] (ieee80211_stop+0x0/0x4c0 [mac80211]) Additionally, one would get this, going on regarless of the WLAN interface state, going on forever: [ 2252.859985] wlan0: direct probe to 00:90:4c:60:04:00 (try -996717525) [ 2253.055419] wlan0: direct probe to 00:90:4c:60:04:00 (try -996717524) [ 2253.250610] wlan0: direct probe to 00:90:4c:60:04:00 (try -996717523) [ 2253.446014] wlan0: direct probe to 00:90:4c:60:04:00 (try -996717522) [ 2253.641357] wlan0: direct probe to 00:90:4c:60:04:00 (try -996717521) Signed-off-by: Juuso Oikarinen Reviewed-by: Johannes Berg Signed-off-by: John W.
