Hi, I found a race condition in my previous patches when scan results where queued and we got a stop request before processing them. I have now fixed this by checking whether we're scanning before sending results and by not queuing new scan results after we have stopped. Two new changes from v2: * make sure we still have sched_scan_req when trying to send scan results; * don't queue scan results events if the scheduled scan is not running; And the previous changes, from v1 were: * fixed @ssid description in cfg80211_sched_scan_request(); * cleaned the 'out_free' inside an else block; * use a trace event class for sched_scan_start/_stop and hw_scan; * a couple of patches sent separately with more common trace classes; * removed the FIF_BCN_PRBRESP_PROMISC flag on sched_scanning; * moved conditions a bit around in ieee80211_rx_h_passive_scan(), so the IEEE80211_RX_IN_SCAN flag is not needed in sched_scan; * sent a separate patch not to drop skb->len < 24 frames in scans; * fixed freeing the ies array when the sched_scan_start driver callback fails; Cheers, Luca.
