      ath9k: Fix kernel panic during driver initilization · 07445f68
      Mohammed Shafi Shajakhan 提交于
      all works need to be initialized before ieee80211_register_hw
      to prevent mac80211 call backs such as drv_start, drv_config
      getting started. otherwise we would queue/cancel works before
      initializing them and it leads to kernel panic.
      this issue can be recreated with the following script
      in Chrome laptops with AR928X cards, with background scan
      running (or) Network manager is running
      
      while true
      do
      sudo modprobe -v ath9k
      sleep 3
      sudo modprobe -r ath9k
      sleep 3
      done

      mwifiex: handle association failure case correctly · b7097eb7
      Amitkumar Karwar 提交于
      Currently even if association is failed "iw link" shows some
      information about connected BSS and "Tx timeout" error is seen in
      dmesg log.
      
      This patch fixes below issues in the code to handle assoc failure
      case correctly.
      1) "status" variable in mwifiex_wait_queue_complete() is not
      correctly updated. Hence driver doesn't inform cfg80211 stack
      about association failure.
      2) During association network queues are stopped but carrier is
      not cleared, which gives Tx timeout error in failure case
