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 <juuso.oikarinen@xxxxxxxxx> Reviewed-by: Johannes Berg <johannes@xxxxxxxxxxxxxxxx> --- net/mac80211/work.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/net/mac80211/work.c b/net/mac80211/work.c index 7e708d5..1e1ea30 100644 --- a/net/mac80211/work.c +++ b/net/mac80211/work.c @@ -869,6 +869,7 @@ static void ieee80211_work_work(struct work_struct *work) break; case IEEE80211_WORK_ABORT: rma = WORK_ACT_TIMEOUT; + break; case IEEE80211_WORK_DIRECT_PROBE: rma = ieee80211_direct_probe(wk); break; -- 1.6.3.3 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
