      mwl8k: fix firmware command serialisation · 618952a7
      Lennert Buytenhek authored
      The current mwl8k_priv->fw_lock spinlock doesn't actually protect
      against multiple commands being submitted at once, as it is not kept
      held over the entire firmware command submission.  And since waiting
      for command completion sleeps, we can't use a spinlock anyway.
      
      To fix mwl8k firmware command serialisation properly, we have the
      following requirements:
      - Some commands require that the packet transmit path is idle when
        the command is issued.  (For simplicity, we'll just quiesce the
        transmit path for every command.)
      - There are certain sequences of commands that need to be issued to
        the hardware sequentially, with no other intervening commands.
      
      This leads to an implementation of a "firmware lock" as a mutex that
      can be taken recursively, and which is taken by both the low-level
      command submission function (mwl8k_post_cmd) as well as any users of
      that function that require issuing of an atomic sequence of commands,
      and quiesces the transmit path whenever it's taken.

      mwl8k: mwl8k_queue_work() cleanup · 950d5b01
      Lennert Buytenhek authored
      Delete most of the mwl8k_work_struct fields and options, since most
      of them are unused or never changed from their defaults:
      - We always use priv->config_wq, so delete the wqueue argument from
        mwl8k_queue_work().
      - MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all
        callers sleep for request completion, so sleep unconditionally.
      - MWL8K_WQ_FREE_WORKSTRUCT is never used.
      - MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally.
      - timeout_ms/txwait_attempts/tx_timeout_ms are never changed from
        their defaults, so just hardcode these in the workqueue worker.
      - step is never used.

      mwl8k: mwl8k_txq_xmit() rework · 23b33906
      Lennert Buytenhek authored
      Various mwl8k_txq_xmit changes:
      - Extract the QoS field before adding the DMA header.
      - Only write to tx->status once, and only after all the other
        descriptor fields have been set.
      - Do all tx state manipulation under the tx spinlock.
      - Remove the priv->inconfig check, as all transmit queues will
        be frozen during config cycles, so we won't ever be asked to
        transmit if a config cycle is running.
      - Remove some more dead code.

      mwl8k: don't touch 'command done' interrupt during firmware load · d4b70570
      Lennert Buytenhek authored
      Since firmware load commands don't generate 'command done' interrupts
      like normal commands do, polling for command done interrupts just
      unnecessarily slows down the firmware load process.  Removing this bit
      of code speeds up loading a typical firmware image from 840 msec to
      180 msec.

      mwl8k: dma header manipulations can't fail · 76266b2a
      Lennert Buytenhek authored
      Adding and removing the DMA header that the mwl8k hardware requires
      on tx and provides on rx can never fail, since we are guaranteed to
      have enough headroom on the tx path to expand the packet, and we only
      ever shrink the packet on the rx path.  (And on both paths we are
      guaranteed to be the only user of the skb we are handling.)
      
      This allows removing all of the skb clone handling in the tx and tx
      reclaim paths, and eliminates error checks in both the tx and rx
      paths, simplifying the code a bit more.

      mwl8k: fix mwl8k_configure_filter() parameter lifetime issue · e81cd2d6
      Lennert Buytenhek authored
      mwl8k_configure_filter() passes pointers to total_flags and the
      multicast address list to a workqueue function, while there is no
      guarantee that those pointers will still be valid by the time the
      workqueue function runs.
      
      Solve this by passing total_flags by value, and by passing an
      already built multicast address setup command packet to the workqueue
      function so that we don't have to look at the multicast address list
      itself outside of mwl8k_configure_filter().
      
      Also, since ->configure_filter() can sleep now, wait synchronously
      for the worker to finish.

      ath9k: Fix bug in retrieving average beacon rssi · ff360416
      Vasanthakumar Thiagarajan authored
      Currently the beacon rssi that LPF gives is divided and rounded
      up by ATH_RSSI_EP_MULTIPLIER twice. This will leave the incorrect rssi
      in ANI. Having correct rssi in ANI fixes the connection stability at
      < 30dB rssi range. This patch removes the unncessary computation of average
      rssi over already valid average rssi. Also removes the redundant macros to
      find average rssi.

      cfg80211: fix dangling scan request checking · ad002395
      Johannes Berg authored
      My patch "cfg80211: fix deadlock" broke the code it
      was supposed to fix, the scan request checking. But
      it's not trivial to put it back the way it was, since
      the original patch had a deadlock.
      
      Now do it in a completely new way: queue the check
      off to a work struct, where we can freely lock. But
      that has some more complications, like needing to
      wait for it to be done before the wiphy/rdev can be
      destroyed, so some code is required to handle that.

      This expands on the current fwded_frames stat counter which should be equal to
      the total of these two new counters.  The new counters are called "fwded_mcast"
      and "fwded_unicast".

      wl1251: halt the embedded CPU before loading firmware · bcd64e0c
      Bob Copeland authored
      After initial power-up, the embedded cpu is usually halted.  However,
      if we down the interface and only do a soft reset before bringing
      the interface back up, it will still be running and the firmware
      loading code will bail out.  This change halts the CPU before loading
      the firmware, enabling a second call to wl1251_boot() to succeed
      without a hard reset.

      mac80211: Decouple fail_avg stats used by mesh from rate control algorithm. · bfc32e6a
      Javier Cardona authored
      Mesh uses the tx failure average to compute the (m)path metric.  This used to
      be done inside the rate control module.  This patch breaks the dependency
      between the mesh stack and the rate control algorithm.  Mesh will now work
      independently of the chosen rate control algorithm.
      
      The mesh stack keeps a moving average of the average transmission losses for
      each mesh peer station.  If the fail average exceeds a certain threshold, the
      peer link is marked as broken.
