      ipw2100: register pm_qos request before registering pci driver · 2f81b471
      John W. Linville authored
      It is necessary to call pm_qos_add_request prior to calling
      pm_qos_update_request.  It was revealed that ipw2100 has been
      doing this wrong since "pm_qos: Get rid of the allocation in
      pm_qos_add_request()" (commit 82f68251)
      added a WARN that results in the following backtrace:
      
      WARNING: at kernel/pm_qos_params.c:264 pm_qos_update_request+0x5e/0x70()

      iwlagn: fix rts cts protection · 94597ab2
      Johannes Berg authored
      Currently the driver will try to protect all frames,
      which leads to a lot of odd things like sending an
      RTS with a zeroed RA before multicast frames, which
      is clearly bogus.
      
      In order to fix all of this, we need to take a step
      back and see what we need to achieve:
       * we need RTS/CTS protection if requested by
         the AP for the BSS, mac80211 tells us this
       * in that case, CTS-to-self should only be
         enabled when mac80211 tells us
       * additionally, as a hardware workaround, on
         some devices we have to protect aggregated
         frames with RTS
      
      To achieve the first two items, set up the RXON
      accordingly and set the protection required flag
      in the transmit command when mac80211 requests
      protection for the frame.
      
      To achieve the last item, set the rate-control
      RTS-requested flag for all stations that we have
      aggregation sessions with, and set the protection
      required flag when sending aggregated frames (on
      those devices where this is required).
      
      Since otherwise bugs can occur, do not allow the
      user to override the RTS-for-aggregation setting
      from sysfs any more.
      
      Finally, also clean up the way all these flags get
      set in the driver and move everything into the
      device-specific functions.

      cfg80211: fix locking in action frame TX · fe100acd
      Johannes Berg authored
      Accesses to "wdev->current_bss" must be
      locked with the wdev lock, which action
      frame transmission is missing.
