      cfg80211: sched_scan_mtx lock in cfg80211_conn_work() · 90e0970f

      ("cfg80211: always check for scan end on P2P device")
      
      cfg80211_conn_scan() which requires sched_scan_mtx to be held can be called
      from cfg80211_conn_work(). Without this we are hitting multiple warnings like
      the following:

      iwlwifi: dvm: fix the passive-no-RX workaround · b8730b40
      Johannes Berg authored
      Alex Romosan reported that since the mac80211 changes in
      "mac80211: start auth/assoc timeout on frame status" and
      the subsequent fixes in "mac80211: fix auth/assoc timeout
      handling" (commits 1672c0e3 and 89afe614) there's
      sometimes an issue connecting to a 5 GHz network with the
      iwlwifi DVM driver.
      
      The reason appears to be that since these commits any bad
      TX status makes mac80211 immediately try again, causing
      all of the authentication attempts to be quickly rejected
      by the firmware as it hasn't heard a beacon yet. Before,
      it would wait for the timeout regardless of status.
      
      To fix this, invoke the passive-no-RX workaround when not
      associated yet as well. This will cause the first frame
      to get lost, but then the driver will stop the queues and
      the second attempt will only be transmitted after hearing
      a beacon, thus delaying it appropriately to not make the
      firmware reject it again.

      mac80211: Don't restart sta-timer if not associated. · 370bd005
      Ben Greear authored
      I found another crash when deleting lots of virtual stations
      in a congested environment.  I think the problem is that
      the ieee80211_mlme_notify_scan_completed could call
      ieee80211_restart_sta_timer for a stopped interface
      that was about to be deleted.
      
      With the following patch I am unable to reproduce the
      crash.

      cfg80211: always check for scan end on P2P device · f9f47529
      Johannes Berg authored
      If a P2P device wdev is removed while it has a scan, then the
      scan completion might crash later as it is already freed by
      that time. To avoid the crash always check the scan completion
      when the P2P device is being removed for some reason. If the
      driver already canceled it, don't want and free it, otherwise
      warn and leak it to avoid later crashes.
      
      In order to do this, locking needs to be changed away from the
      rdev mutex (which can't always be guaranteed). For now, use
      the sched_scan_mtx instead, I'll rename it to just scan_mtx in
      a later patch.
