      ath9k_htc: Fix probe failure if CONFIG_USB_DEBUG enabled · 490b3f4e
      Rajkumar Manoharan authored
      Since the endpoint descriptors (EP3 & EP4) were changed from Interrupt
      to Bulk type by firmware, the urb submission done on Bulk pipes.
      And the recent commit "check the endpoint type against the pipe type"
      added aditional error checking against pipe types under CONFIG_USB_DEBUG.
      
      So bmAttribute has to be updated for both EP3 & EP4 before submitting
      urbs on that pipe. This patch resolves the following failure.

      ath9k_hw: Fix AR9280 surprise removal during frequent idle on/off · f119da30
      Vasanthakumar Thiagarajan authored
      Bit 22 of AR_WA should be set to fix the situation where chip reset
      is asynchronous to clock of analog shift registers, such that when
      reset is released, it could mess up the values of analog shift registers
      and cause some hw issue on AR9280.
      
      This bit is write only, but the driver does a read-modify-write
      on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave()
      during radio disable. This causes surprise removal of hw. It can
      never recover from this state and the hw will become usable only
      after a power on/off cycle, and sometimes only during a cold reboot.
      
      This issue can be triggered by doing frequent roaming with the
      simple/test-roam script available from the wifi-test project [1]
      when roaming between APs quickly. When roaming there is a is a high
      possibility that the device being put into idle (radio disable) state
      by mac80211 during AUTH->ASSOC. A device hardware reset would fail
      and the kernel would output:

      This is currently only reproducible with some HB92 (Half Mini-PCIE)
      cards but the fix applies to all AR9280 cards. This patch fixes this
      issue by setting bit 22 during radio disable.
      
      This patch has fixes for all kernels that has ath9k.

      libertas: terminate scan when stopping interface · 2e30168b
      Daniel Drake authored
      There are currently no provisions in place to ensure that the scanning
      task has been stopped when the interface is stopped or removed.
      
      This can result in a WARNING at net/wireless/core.c:643 and other badness
      when you remove the module while a scan is happening.
      
      Terminate the scanning task during interface stop.

      mac80211: unset SDATA_STATE_OFFCHANNEL when cancelling a scan · 352ffad6
      Brian Cavagnolo authored
      For client STA interfaces, ieee80211_do_stop unsets the relevant
      interface's SDATA_STATE_RUNNING state bit prior to cancelling an
      interrupted scan.  When ieee80211_offchannel_return is invoked as
      part of cancelling the scan, it doesn't bother unsetting the
      SDATA_STATE_OFFCHANNEL bit because it sees that the interface is
      down.  Normally this doesn't matter because when the client STA
      interface is brought back up, it will probably issue a scan.  But
      in some cases (e.g., the user changes the interface type while it
      is down), the SDATA_STATE_OFFCHANNEL bit will remain set.  This
      prevents the interface queues from being started.  So we
      cancel the scan before unsetting the SDATA_STATE_RUNNING bit.

      ath9k: check old power mode before clearing cycle counters · fbb078fc
      Felix Fietkau authored
      ath9k_ps_wakeup() clears the cycle counters after waking up the
      hardware using ath9k_hw_setpower, however if power save is disabled,
      then the counters will contain useful data, which then gets discarded.
      Fix this by checking the old power mode before discarding any data.
