      iwlwifi: disable tx on beacon update notification · c91c3efc
      Abhijeet Kolekar authored
      On beacon change update notification from mac we are not disabling
      the tx in adhoc mode. Mac sends BSS_CHANGED_BEACON_ENABLED when
      station leaves IBSS. Driver should indicate uCode to not to send
      anything on receiving this notification.
      
      Functionality to indicate uCode is duplicated across
      two notifications so created a common function called iwl_set_no_assoc.
      
      Fix the issue at
      http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2133.

      iwlwifi: fix iwl_queue_used bug when read_ptr == write_ptr · c8106d76
      Zhu Yi authored
      When txq read_ptr equals to write_ptr, iwl_queue_used should
      always return false. Because there is no used TFD in this case.
      
      This is a complementary fix to the fix already included in commit "iwl3945:
      fix panic in iwl3945 driver". Both fixes are needed to address the panic
      below.
      
      This problem was discussed on linux-wireless in

      mac80211: add missing sanity checks for action frames · d7907448
      Felix Fietkau authored
      Various missing sanity checks caused rejected action frames to be
      interpreted as channel switch announcements, which can cause a client
      mode interface to switch away from its operating channel, thereby losing
      connectivity. This patch ensures that only spectrum management action
      frames are processed by the CSA handling function and prevents rejected
      action frames from getting processed by the MLME code.

      mac80211: fix queue selection for packets injected via monitor interface · 045cfb71
      Lennert Buytenhek authored
      Commit 'mac80211: fix skb buffering issue' added an ->ndo_select_queue()
      for monitor interfaces which can end up dereferencing ieee802_1d_to_ac[]
      beyond the end of the array for injected data packets (as skb->priority
      isn't guaranteed to be zero or within [0:7]), which then triggers the
      WARN_ON in net/core/dev.c:dev_cap_txqueue().  Fix this by always setting
      the priority to zero on injected data frames.
