      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.

      cfg80211: Simplify the handling of regulatory indoor setting · 0c4ddcd2

      Directly update the indoor setting without wrapping it as
      a regulatory request, to simplify the processing.

      bridge: add vlan info to bridge setlink and dellink notification messages · b7853d73
      Roopa Prabhu authored
      
      
      vlan add/deletes are not notified to userspace today. This patch adds
      vlan info to bridge newlink/dellink notifications generated from the
      bridge driver. Notifications use the RTEXT_FILTER_BRVLAN_COMPRESSED
      flag to compress vlans into ranges whereever applicable.
      
      The size calculations does not take ranges into account for
      simplicity.  This has the potential for allocating a larger skb than
      required.
      
      There is an existing inconsistency with bridge NEWLINK and DELLINK
      change notifications. Both generate NEWLINK notifications.  Since its
      always a NEWLINK notification, this patch includes all vlans the port
      belongs to in the notification. The NEWLINK and DELLINK request
      messages however only include the vlans to be added and deleted.
