      cfg80211: make aware of net namespaces · 463d0183
      Johannes Berg authored
      In order to make cfg80211/nl80211 aware of network namespaces,
      we have to do the following things:
      
       * del_virtual_intf method takes an interface index rather
         than a netdev pointer - simply change this
      
       * nl80211 uses init_net a lot, it changes to use the sender's
         network namespace
      
       * scan requests use the interface index, hold a netdev pointer
         and reference instead
      
       * we want a wiphy and its associated virtual interfaces to be
         in one netns together, so
          - we need to be able to change ns for a given interface, so
            export dev_change_net_namespace()
          - for each virtual interface set the NETIF_F_NETNS_LOCAL
            flag, and clear that flag only when the wiphy changes ns,
            to disallow breaking this invariant
      
       * when a network namespace goes away, we need to reparent the
         wiphy to init_net
      
       * cfg80211 users that support creating virtual interfaces must
         create them in the wiphy's namespace, currently this affects
         only mac80211
      
      The end result is that you can now switch an entire wiphy into
      a different network namespace with the new command
      	iw phy#<idx> set netns <pid>
      and all virtual interfaces will follow (or the operation fails).

      nl80211: Check iftype in cfg80211 code · eec60b03
      Jouni Malinen authored
      We do not want to require all the drivers using cfg80211 to need to do
      this. In addition, make the error values consistent by using
      EOPNOTSUPP instead of semi-random assortment of errno values.

      nl80211: Remove NL80211_CMD_SET_MGMT_EXTRA_IE · 65fc73ac
      Jouni Malinen authored
      The functionality that NL80211_CMD_SET_MGMT_EXTRA_IE provided can now
      be achieved with cleaner design by adding IE(s) into
      NL80211_CMD_TRIGGER_SCAN, NL80211_CMD_AUTHENTICATE,
      NL80211_CMD_ASSOCIATE, NL80211_CMD_DEAUTHENTICATE, and
      NL80211_CMD_DISASSOCIATE.
      
      Since this is a very recently added command and there are no known (or
      known planned) applications using NL80211_CMD_SET_MGMT_EXTRA_IE and
      taken into account how much extra complexity it adds to the IE
      processing we have now (and need to add in the future to fix IE order
      in couple of frames), it looks like the best option is to just remove
      the implementation of this command for now. The enum values themselves
      are left to avoid changing the nl80211 command or attribute numbers.

      nl80211: Add MLME primitives to support external SME · 636a5d36
      Jouni Malinen authored
      This patch adds new nl80211 commands to allow user space to request
      authentication and association (and also deauthentication and
      disassociation). The commands are structured to allow separate
      authentication and association steps, i.e., the interface between
      kernel and user space is similar to the MLME SAP interface in IEEE
      802.11 standard and an user space application takes the role of the
      SME.
      
      The patch introduces MLME-AUTHENTICATE.request,
      MLME-{,RE}ASSOCIATE.request, MLME-DEAUTHENTICATE.request, and
      MLME-DISASSOCIATE.request primitives. The authentication and
      association commands request the actual operations in two steps
      (assuming the driver supports this; if not, separate authentication
      step is skipped; this could end up being a separate "connect"
      command).
      
      The initial implementation for mac80211 uses the current
      net/mac80211/mlme.c for actual sending and processing of management
      frames and the new nl80211 commands will just stop the current state
      machine from moving automatically from authentication to association.
      Future cleanup may move more of the MLME operations into cfg80211.
      
      The goal of this design is to provide more control of authentication and
      association process to user space without having to move the full MLME
      implementation. This should be enough to allow IEEE 802.11r FT protocol
      and 802.11s SAE authentication to be implemented. Obviously, this will
      also bring the extra benefit of not having to use WEXT for association
      requests with mac80211. An example implementation of a user space SME
      using the new nl80211 commands is available for wpa_supplicant.
      
      This patch is enough to get IEEE 802.11r FT protocol working with
      over-the-air mechanism (over-the-DS will need additional MLME
      primitives for handling the FT Action frames).

      nl80211: Provide access to STA TX/RX packet counters · 98c8a60a
      Jouni Malinen authored
      The TX/RX packet counters are needed to fill in RADIUS Accounting
      attributes Acct-Output-Packets and Acct-Input-Packets. We already
      collect the needed information, but only the TX/RX bytes were
      previously exposed through nl80211. Allow applications to fetch the
      packet counters, too, to provide more complete support for accounting.

      mac80211: split IBSS/managed code · 46900298
      Johannes Berg authored
      This patch splits out the ibss code and data from managed (station) mode.
      The reason to do this is to better separate the state machines, and have
      the code be contained better so it gets easier to determine what exactly
      a given change will affect, that in turn makes it easier to understand.
      
      This is quite some churn, especially because I split sdata->u.sta into
      sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that
      way. I've also shuffled around some code -- null function sending is only
      applicable to managed interfaces so put that into that file, some other
      functions are needed from various places so put them into util, and also
      rearranged the prototypes in ieee80211_i.h accordingly.
