      nl80211: Add notification for dropped Deauth/Disassoc · cf4e594e
      Jouni Malinen 提交于
      Add a new notification to indicate that a received, unprotected
      Deauthentication or Disassociation frame was dropped due to
      management frame protection being in use. This notification is
      needed to allow user space (e.g., wpa_supplicant) to implement
      SA Query procedure to recover from association state mismatch
      between an AP and STA.
      
      This is needed to avoid getting stuck in non-working state when MFP
      (IEEE 802.11w) is used and a protected Deauthentication or
      Disassociation frame is dropped for any reason. After that, the
      station would silently discard any unprotected Deauthentication or
      Disassociation frame that could be indicating that the AP does not
      have association for the STA (when the Reason Code would be 6 or 7).
      IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism.

      cfg80211: Add connection quality monitoring support to nl80211 · d6dc1a38
      Juuso Oikarinen 提交于
      Add support for basic configuration of a connection quality monitoring to the
      nl80211 interface, and basic support for notifying about triggered monitoring
      events.
      
      Via this interface a user-space connection manager may configure and receive
      pre-warning events of deteriorating WLAN connection quality, and start
      preparing for roaming in advance, before the connection is already lost.
      
      An example usage of such a trigger is starting scanning for nearby AP's in
      an attempt to find one with better connection quality, and associate to it
      before the connection characteristics of the existing connection become too bad
      or the association is even lost, leading in a prolonged delay in connectivity.
      
      The interface currently supports only RSSI, but it could be later extended
      to include other parameters, such as signal-to-noise ratio, if need for that
      arises.

      cfg80211/mac80211: allow registering for and sending action frames · 026331c4
      Jouni Malinen 提交于
      This implements a new command to register for action frames
      that userspace wants to handle instead of the in-kernel
      rejection. It is then responsible for rejecting ones that
      it decided not to handle. There is no unregistration, but
      the socket can be closed for that.
      
      Frames that are not registered for will not be forwarded
      to userspace and will be rejected by the kernel, the
      cfg80211 API helps implementing that.
      
      Additionally, this patch adds a new command that allows
      doing action frame transmission from userspace. It can be
      used either to exchange action frames on the current
      operational channel (e.g., with the AP with which we are
      currently associated) or to exchange off-channel Public
      Action frames with the remain-on-channel command.

      nl80211: Event notifications for MLME events · 6039f6d2
      Jouni Malinen 提交于
      Add new nl80211 event notifications (and a new multicast group, "mlme")
      for informing user space about received and processed Authentication,
      (Re)Association Response, Deauthentication, and Disassociation frames in
      station and IBSS modes (i.e., MLME SAP interface primitives
      MLME-AUTHENTICATE.confirm, MLME-ASSOCIATE.confirm,
      MLME-REASSOCIATE.confirm, MLME-DEAUTHENTICATE.indicate, and
      MLME-DISASSOCIATE.indication). The event data is encapsulated as the 802.11
      management frame since we already have the frame in that format and it
      includes all the needed information.
      
      This is the initial step in providing MLME SAP interface for
      authentication and association with nl80211. In other words, kernel code
      will act as the MLME and a user space application can control it as the
      SME.

      cfg80211/nl80211: remove usage of CONFIG_NL80211 · 633e24ed
      Reinette Chatre 提交于
      The scan capability added to cfg80211/nl80211 introduced a
      dependency on nl80211 by cfg80211. We can thus no longer have
      just cfg80211 without nl80211. Specifically, cfg80211_scan_done()
      calls nl80211_send_scan_aborted() or nl80211_send_scan_done().
      
      Now we remove the option for user to select nl80211. It will always
      be compiled if user selects cfg80211.
