      iwlwifi: disable WoWLAN if !CONFIG_PM_SLEEP · fcb6ff5e
      Johannes Berg authored
      If CONFIG_PM_SLEEP is disabled, then iwlwifi doesn't
      support suspend/resume handlers and thus mac80211
      (correctly) refuses advertising WoWLAN. Disable
      WoWLAN in the driver in this case.

      mac80211: fix non RCU-safe sta_list manipulation · 794454ce
      Arik Nemtsov authored
      sta_info_cleanup locks the sta_list using rcu_read_lock however
      the delete operation isn't rcu safe. A race between sta_info_cleanup
      timer being called and a STA being removed can occur which leads
      to a panic while traversing sta_list. Fix this by switching to the
      RCU-safe versions.

      bcma: add ext PA workaround for BCM4331 and BCM43431 · 69aaedd3
      Seth Forshee authored
      MacBook Pro models with BCM4331 wireless have been found to have the ext
      PA lines disabled after resuming from S3 without external power attach.
      This causes them to be unable to transmit. Add a workaround to ensure
      that the ext PA lines are enabled on BCM4331. Also extend all handling
      of ext PA line muxing to BCM43431 as is done in the Broadcom SDK.

      Remove spinlock as atomic_t can be used instead. Note we use only 16
      lower bits, upper bits are changed but we impilcilty cast to u16.

      mac80211: clean up remain-on-channel on interface stop · 71ecfa18
      Johannes Berg authored
      When any interface goes down, it could be the one that we
      were doing a remain-on-channel with. We therefore need to
      cancel the remain-on-channel and flush the related work
      structs so they don't run after the interface has been
      removed or even destroyed.
      
      It's also possible in this case that an off-channel SKB
      was never transmitted, so free it if this is the case.
      Note that this can also happen if the driver finishes
      the off-channel period without ever starting it.

      Since my commit
        iwlwifi: use valid TX/RX antenna from hw_params
      the config values are pure overrides, not the
      real values for all hardware. Therefore, the
      EEPROM TX power reading code checks the wrong
      values, it should check the hw_params values.

      mac80211: Fix Unreachable Mesh Station Problem when joining to another MBSS · b8bacc18
      Chun-Yeow Yeoh authored
      Mesh station that joins an MBSS is reachable using mesh portal with 6
      address frame by mesh stations from another MBSS if these two different
      MBSSes are bridged. However, if the mesh station later moves into the
      same MBSS of those mesh stations, it is unreachable by mesh stations
      in the MBSS due to the mpp_paths table is not deleted. A quick fix
      is to perform mesh_path_lookup, if it is available for the target
      destination, mpp_path_lookup is not performed. When the mesh station
      moves back to its original MBSS, the mesh_paths will be deleted once
      expired. So, it will be reachable using mpp_path_lookup again.

      when cfg80211_ibss_joined() is called by driver inside
      .join_ibss handler.
      
      This patch fixes the problem by changing 'sme_state' in ibss path
      and having WARN_ON() check for 'sme_state' similar to infra

      mwifiex: invalidate bss config before setting channel for uAP · f0e3bd23
      Avinash Patil authored
      Mark bss_config parameters as invalid before setting AP channel.
      This prevents from setting invalid parameters while setting AP
      channel to FW.

      mac80211: run scan after finish connection monitoring · 925e64c3

      commit 133d40f9
      Author: Stanislaw Gruszka <sgruszka@redhat.com>
      Date:   Wed Mar 28 16:01:19 2012 +0200
      
          mac80211: do not scan and monitor connection in parallel
      
      add bug, which make possible to start a scan and never finish it, so
      make every new scanning request finish with -EBUSY error. This can
      happen on code paths where we finish connection monitoring and clear
      IEEE80211_STA_*_POLL flags, but do not check if scan was deferred.
      This patch fixes those code paths.
