From d57336e3f2dd7c2d1fbe4a8323029869fb6e1f00 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Sun, 30 Apr 2006 22:09:07 +0100 Subject: [PATCH] softmac: make non-operational after being stopped zd1211 with softmac and wpa_supplicant revealed an issue with softmac and the use of workqueues. Some of the work functions actually reschedule themselves, so this meant that there could still be pending work after flush_scheduled_work() had been called during ieee80211softmac_stop(). This patch introduces a "running" flag which is used to ensure that rescheduling does not happen in this situation. I also used this flag to ensure that softmac's hooks into ieee80211 are non-operational once the stop operation has been started. This simply makes softmac a little more robust, because I could crash it easily by receiving frames in the short timeframe after shutting down softmac and before turning off the ZD1211 radio. (ZD1211 is now fixed as well!) Signed-off-by: Daniel Drake Acked-by: Johannes Berg Signed-off-by: John W.
