      cfg80211: Allow TDLS peer AID to be configured for VHT · 5e4b6f56
      Jouni Malinen authored
      VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current
      design for TDLS is to first add a dummy STA entry before completing TDLS
      Setup and then update information on this STA entry based on what was
      received from the peer during the setup exchange.
      In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just
      like this is used in AP mode to set the AID of an association station.
      However, existing cfg80211 validation rules prevent this attribute from
      being used with set_station operation. To avoid interoperability issues
      between different kernel and user space version combinations, introduce
      a new nl80211 attribute for the purpose of setting TDLS peer AID. This
      attribute can be used in both the new_station and set_station
      operations. It is not supposed to be allowed to change the AID value
      during the lifetime of the STA entry, but that validation is left for
      drivers to do in the change_station callback.

      nl80211: explicit userspace MPM · bb2798d4
      Thomas Pedersen authored
      Secure mesh had the implicit requirement that the Mesh
      Peering Management entity be in userspace.  However
      userspace might want to implement an open MPM as well, so
      specify a mesh setup parameter to indicate this.

      cfg80211: Extend support for IEEE 802.11r Fast BSS Transition · 355199e0
      Jouni Malinen authored
      Add NL80211_CMD_UPDATE_FT_IES to support update of FT IEs to the WLAN
      driver and NL80211_CMD_FT_EVENT to send FT events from the WLAN driver.
      This will carry the target AP's MAC address along with the relevant
      Information Elements. This event is used to report received FT IEs
      (MDIE, FTIE, RSN IE, TIE, RICIE). These changes allow FT to be supported
      with drivers that use an internal SME instead of user space option (like
      FT implementation in wpa_supplicant with mac80211-based drivers).

      nl80211: allow splitting wiphy information in dumps · 3713b4e3
      Johannes Berg authored
      The per-wiphy information is getting large, to the point
      where with more than the typical number of channels it's
      too large and overflows, and userspace can't get any of
      the information at all.
      To address this (in a way that doesn't require making all
      messages bigger) allow userspace to specify that it can
      deal with wiphy information split across multiple parts
      of the dump, and if it can split up the data. This also
      splits up each channel separately so an arbitrary number
      of channels can be supported.
      Additionally, since GET_WIPHY has the same problem, add
      support for filtering the wiphy dump and get information
      for a single wiphy only, this allows userspace apps to
      use dump in this case to retrieve all data from a single
      As userspace needs to know if all this this is supported,
      add a global nl80211 feature set and include a bit for
      this behaviour in it.

      cfg80211: comprehensively check station changes · 77ee7c89
      Johannes Berg authored
      The station change API isn't being checked properly before
      drivers are called, and as a result it is difficult to see
      what should be allowed and what not.
      In order to comprehensively check the API parameters parse
      everything first, and then have the driver call a function
      (cfg80211_check_station_change()) with the additionally
      information about the kind of station that is being changed;
      this allows the function to make better decisions than the
      old code could.
      While at it, also add a few checks, particularly in mesh
      and clarify the TDLS station lifetime in documentation.
      To be able to reduce a few checks, ignore any flag set bits
      when the mask isn't set, they shouldn't be applied then.

      nl80211: renumber NL80211_FEATURE_FULL_AP_CLIENT_STATE · 932dd97c
      Johannes Berg authored
      Adding the flag to mac80211 already without testing was
      clearly a mistake, one that we now pay for by having to
      reserve bit 13 forever. The problem is cfg80211 doesn't
      allow capability/rate changes for station entries that
      were added unassociated, so the station entries cannot
      be set up properly when marked associated.
      Change the NL80211_FEATURE_FULL_AP_CLIENT_STATE value
      to make it clear to userspace implementations that all
      current kernels don't actually support it, even though
      the previous bit is set, and of course also remove the
      flag from mac80211 until we test and fix the issues.

      cfg80211: Pass station (extended) capability info to kernel · 9d62a986
      Jouni Malinen authored
      The information of the peer's capabilities and extended capabilities are
      required for the driver to perform TDLS Peer UAPSD operations and off
      channel operations. This information of the peer is passed from user space
      using NL80211_CMD_SET_STATION command. This commit enhances
      the function nl80211_set_station to pass the capability information of
      the peer to the driver.
      Similarly, there may be need for capability information for other modes,
      so allow this to be provided with both add_station and change_station.

      cfg80211: expand per-station byte counters to 64bit · 42745e03
      Vladimir Kondratiev authored
      In per-station statistics, present 32bit counters are too small
      for practical purposes - with gigabit speeds, it get overlapped
      every few seconds.
      Expand counters in the struct station_info to be 64-bit.
      Driver can still fill only 32-bit and indicate in @filled
      only bits like STATION_INFO_[TR]X_BYTES; in case driver provides
      full 64-bit counter, it should also set in @filled
      Netlink sends both 32-bit and 64-bit counters, if present, to not
      break userspace.

      nl80211/mac80211: support full station state in AP mode · d582cffb
      Johannes Berg authored
      Today, stations are added already associated. That is
      inefficient if, for example, the driver has no room
      for stations any more because then the station will
      go through the entire auth/assoc handshake, only to
      be kicked out afterwards.
      To address this a bit better, at least with drivers
      using the new station state callback, allow hostapd
      to add stations in unauthenticated mode, just after
      receiving the AUTH frame, before even replying. Thus
      if there's no more space at that point, it can send
      a negative auth frame back. It still needs to handle
      later state transition errors though, of course.

      nl80211/cfg80211: support VHT channel configuration · 3d9d1d66
      Johannes Berg authored
      Change nl80211 to support specifying a VHT (or HT)
      using the control channel frequency (as before) and
      new attributes for the channel width and first and
      second center frequency. The old channel type is of
      course still supported for HT.
      Also change the cfg80211 channel definition struct
      to support these by adding the relevant fields to
      it (and removing the _type field.)
      This also adds new helper functions:
       - cfg80211_chandef_create to create a channel def
         struct given the control channel and channel type,
       - cfg80211_chandef_identical to check if two channel
         definitions are identical
       - cfg80211_chandef_compatible to check if the given
         channel definitions are compatible, and return the
         wider of the two
      This isn't entirely complete, but that doesn't matter
      until we have a driver using it. In particular, it's
       - regulatory checks on the usable bandwidth (if that
         even makes sense)
       - regulatory TX power (database can't deal with it)
       - a proper channel compatibility calculation for the
         new channel types
