      mac80211: minstrel: avoid accessing negative indices in rix_to_ndx() · 3938b45c
      Luciano Coelho authored
      If rix is not found in mi->r[], i will become -1 after the loop.  This value
      is eventually used to access arrays, so we were accessing arrays with a
      negative index, which is obviously not what we want to do.  This patch fixes
      this potential problem.

      cfg80211: fix refcount leak · 2dce4c2b
      Johannes Berg authored
      The code in cfg80211's cfg80211_bss_update erroneously
      grabs a reference to the BSS, which means that it will
      never be freed.

      mac80211: fix allocation in mesh_queue_preq · 59615b5f
      Andrey Yurovsky authored
      We allocate a PREQ queue node in mesh_queue_preq, however the allocation
      may cause us to sleep.  Use GFP_ATOMIC to prevent this.

      ath9k: Fix leak in tx descriptor · cbfe89c6
      Vasanthakumar Thiagarajan authored
      When we reclaim the tx desc, we always assume that the
      last desc is a holding desc, which is not true, and skip it.
      If the tx queue is drained during channel change, internal
      reset and etc, the last descriptor may not be the holding
      descriptor and we fail to reclaim them. This results in the
      following two issues.
      
      1. Tx stuck - We drop all the frames coming from upper layer
      due to shortage in tx desc.
      
      2. Crash - If we fail to reclaim a tx descriptor, we miss to
      update the tx BA window with the seq number of the frame
      associated to that desc, which, at some point, result in
      the following crash due to an assert failure in ath_tx_addto_baw().
      
      This patch fixes these two issues.

      After the recent changes in rfkill, the radio LED used by b43/b43legacy
      did not always initialize correctly.
      
      Both b43 and b43legacy used the deprecated variable radio_enabled in

      fec: fix definition of 5272 version of FEC_X_DES_ACTIVE register
      
      The ColdFire 5272 FEC driver has a different register address map
      than other users of the FEC driver. And its definition of the
      FEC_X_DES_ACTIVE register is incorrect, it should be 0x14.
      The fec interface cannot transmit data with the old value.
