      iwlagn: fix command queue timeout · 282cdb32
      Johannes Berg authored
      If the command queue is constantly busy,
      which can happen in P2P, the hangcheck
      timer will frequently find a command in
      it and will eventually reset the device
      because nothing sets the timestamp for
      this queue when commands are processed.
      
      Fix this by setting the timestamp when
      a command completes.

      iwlagn: fix stack corruption · 456fc37e
      Johannes Berg authored
      Alexander reported a strange crash in iwlagn that
      Meenakshi and Wey couldn't reproduce. I just ran
      into the same issue and tracked it down to stack
      corruption. This fixes it.
      
      The problem was introduced in
      commit 4b8b99b6e650d0527f3a123744b7459976581d14

      ath9k: Fix kernel panic on unplugging the device · 6a6b3f3e
      Mohammed Shafi Shajakhan authored
      when the device is yanked out ath_pci_remove starts doing the cleanups,
      unregistering the hardware etc. so we should bail out immediately when
      we get drv_flush callback from mac80211 when the card is being unplugged.
      the panic occurs after we had associated to an AP.

      mac80211: fix missing sta_lock in __sta_info_destroy · 4bae7d97
      Johannes Berg authored
      Since my commit 34e89507
      ("mac80211: allow station add/remove to sleep") there is
      a race in mac80211 when it clears the TIM bit because a
      sleeping station disconnected, the spinlock isn't held
      around the relevant code any more. Use the right API to
      acquire the spinlock correctly.
