      mac80211: preserve more bits when building QoS header · 32910bb9
      Johannes Berg authored
      Michael Braun reported that when trying to inject A-MSDUs over
      monitor interfaces, the frame doesn't come out right since the
      QoS header A-MSDU bit is overwritten.
      
      Rather than adding that bit specifically simply preserve those
      bits that we don't set here, since we typically get here with
      a zeroed-out QoS header anyway.

      mac80211: filter multicast data packets on AP / AP_VLAN · 72f15d53
      Michael Braun authored
      This patch adds filtering for multicast data packets on AP_VLAN
      interfaces that have no authorized station connected and changes
      filtering on AP interfaces to not count stations assigned to
      AP_VLAN interfaces.
      
      This saves airtime and avoids waking up other stations currently
      authorized in this BSS. When using WPA, the packets dropped could
      not be decrypted by any station.
      
      The behaviour when there are no AP_VLAN interfaces is left unchanged.
      
      When there are AP_VLAN interfaces, this patch
      1. adds filtering multicast data packets sent on AP_VLAN interfaces
         that have no authorized station connected.
         No filtering happens on 4addr AP_VLAN interfaces.
      2. makes filtering of multicast data packets sent on AP interfaces
         depend on the number of authorized stations in this bss not
         assigned to an AP_VLAN interface.
      
      Therefore, a new num_mcast_sta counter is added for AP_VLAN interfaces.
      The existing one for AP interfaces is altered to not track stations
      assigned to an AP_VLAN interface.
      
      The new counter is exposed in debugfs.

      mac80211: remove unnecessary num_mcast_sta check · 5f9994bd
      Michael Braun authored
      Checking for num_mcast_sta in __ieee80211_request_smps_ap() is
      unnecessary as sta list will be empty in this case anyway, so
      the list iteration will just exit immediately. Since this isn't
      a "hot" code path, it doesn't really matter, and the next patch
      will redefine num_mcast_sta to make this check invalid.

      mac80211_hwsim: make multi-channel ops const · 246ad56e
      Johannes Berg authored
      Instead of building the multi-channel ops at runtime, declare
      the common ops with a macro and build both that way, so that
      the multi-channel ops can also be const.
      
      As a side effect, due to the removed code, this decreases the
      size of the module (while shifting data from .bss to .text
      due to the newly added const).

      mac80211: remove unnecessary mesh check · 850092db
      Johannes Berg authored
      sta_info_get_bss() is equivalent to sta_info_get() in the
      mesh case, since sta->sdata->bss will be NULL (it's only
      set for AP/AP_VLAN interfaces.) Thus, the mesh check here
      isn't actually needed - remove it.

      mm: split gfp_mask and mapping flags into separate fields · 9c5d760b
      Michal Hocko authored
      mapping->flags currently encodes two different things into a single flag.
      It contains sticky gfp_mask for page cache allocations and AS_ codes used
      to report errors/enospace and other states which are mapping specific.
      Condensing the two semantically unrelated things saves few bytes but it
      also complicates other things.  For one thing the gfp flags space is
      reduced and in fact we are already running out of available bits.  It can
      be assumed that more gfp flags will be necessary later on.
      
      To not introduce the address_space grow (at least on x86_64) we can stick
      it right after private_lock because we have a hole there.
      
      struct address_space {
