      mac80211: fix another race in aggregation start · 15062e6a
      Johannes Berg authored
      Emmanuel noticed that when mac80211 stops the queues
      for aggregation that can leave a packet pending. This
      packet will be given to the driver after the AMPDU
      callback, but as a non-aggregated packet which messes
      up the sequence number etc.
      I also noticed by looking at the code that if packets
      are being processed while we clear the WANT_START bit,
      they might see it cleared already and queue up on
      tid_tx->pending. If the driver then rejects the new
      aggregation session we leak the packet.
      Fix both of these issues by changing this code to not
      stop the queues at all. Instead, let packets queue up
      on the tid_tx->pending queue instead of letting them
      get to the driver, and add code to recover properly
      in case the driver rejects the session.
      (The patch looks large because it has to move two
      functions to before their new use.)
