      cfg80211: add vlan to station add/change tracing · 5d8325ec
      Johannes Berg authored
      
      
      This helps debug issues with VLAN modifications that are otherwise
      not really visible in any tracing/debugging.

      mac80211: avoid duplicate TX path station lookup · 7c10770f
      Johannes Berg authored
      
      
      Instead of looking up the destination station twice in the TX path
      (first to build the header, and then for control processing), save
      it when building the header and use it later in the TX path.
      
      To avoid having to look up the station in the many callers, allow
      those to pass %NULL which keeps the existing lookup.

      mac80211: mesh: avoid pointless station lookup · e33f5569
      Johannes Berg authored
      
      
      In ieee80211_build_hdr(), the station is looked up to build the
      header correctly (QoS field) and to check for authorization. For
      mesh, authorization isn't checked here, and QoS capability is
      mandatory, so the station lookup can be avoided.

      mac80211: drop 4-addr VLAN frames earlier if not connected · a8d15ff0
      Johannes Berg authored
      
      
      If there's no station on the 4-addr VLAN interface, then frames
      cannot be transmitted. Drop such frames earlier, before setting
      up all the information for them.
      
      We should keep the old check though since that code might be used
      for other internally-generated frames.

      mac80211: don't look up destination station twice · 5041006c
      Johannes Berg authored
      
      
      There's no need to look up the destination station twice while
      building the 802.11 header for a given frame if the frame will
      actually be transmitted to the station we initially looked up.
      
      This happens for 4-addr VLAN interfaces and TDLS connections, which
      both directly send the frame to the station they looked up, though
      in the case of TDLS some station conditions need to be checked.
      
      To avoid that, add a variable indicating that we've looked up the
      station that the frame is going to be transmitted to, and avoid the
      lookup/flag checking if it already has been done.
      
      In the TDLS case, also move the authorized/wme_sta flag assignment
      to the correct place, i.e. only when that station is really used.
      Before this change, the new lookup should always have succeeded so
      that the potentially erroneous data would be overwritten.

      mac80211: remove drop_unencrypted code · e8f4fb7c
      Johannes Berg authored
      
      
      This mechanism was historic, and only ever used by IBSS, which
      also doesn't need to have it as it properly manages station's
      802.1X PAE state (or, with WEP, always has a key.)
      
      Remove the mechanism to clean up the code.

      cfg80211: Schedule timeout for all CRDA calls · eeca9fce
      Ilan peer authored
      
      
      Timeout was scheduled only in case CRDA was called due to user hints,
      but was not scheduled for other cases. This can result in regulatory
      hint processing getting stuck in case that there is no CRDA configured.
      
      Change this by scheduling a timeout every time CRDA is called. In
      addition, in restore_regulatory_settings() all pending requests are
      restored (and not only the user ones).

      cfg80211: Add API to change the indoor regulatory setting · 05050753
      Ilan peer authored
      
      
      Previously, the indoor setting configuration assumed that as
      long as a station interface is connected, the indoor environment
      setting does not change. However, this assumption is problematic
      as:
      
      - It is possible that a station interface is connected to a mobile
        AP, e.g., softAP or a P2P GO, where it is possible that both the
        station and the mobile AP move out of the indoor environment making
        the indoor setting invalid. In such a case, user space has no way to
        invalidate the setting.
      - A station interface disconnection does not necessarily imply that
        the device is no longer operating in an indoor environment, e.g.,
        it is possible that the station interface is roaming but is still
        stays indoor.
      
      To handle the above, extend the indoor configuration API to allow
      user space to indicate a change of indoor settings, and allow it to
      indicate weather it controls the indoor setting, such that:
      
      1. If the user space process explicitly indicates that it is going
         to control the indoor setting, do not clear the indoor setting
         internally, unless the socket is released. The user space process
         should use the NL80211_ATTR_SOCKET_OWNER attribute in the command
         to state that it is going to control the indoor setting.
      2. Reset the indoor setting when restoring the regulatory settings in
         case it is not owned by a user space process.
      
      Based on the above, a user space tool that continuously monitors the
      indoor settings, i.e., tracking power setting, location etc., can
      indicate environment changes to the regulatory core.
      
      It should be noted that currently user space is the only provided mechanism
      used to hint to the regulatory core over the indoor/outdoor environment --
      while the country IEs do have an environment setting this has been completely
      ignored by the regulatory core by design for a while now since country IEs
      typically can contain bogus data.

      a regulatory request, to simplify the processing.
