      ath5k: Fix survey · f15a4bb2
      Bruno Randolf authored
      
      
      The old survey implementation was broken and returned nonsense data.
      
      Clear cycle counters and survey data on reset. Since the cycle counters easily
      overflow it's better to keep a local version of collected survey data (in ms
      resolution, instead of clockrate) and update this every time survey is
      retrieved. If survey is retrieved often enough to avoid cycle counter overflows
      this works fine, otherwise we could update survey more often, like ath9k does.
      Still only the survey for the current channel is kept.

      After merge of the rtl8192ce driver, a powerpc build fails with:

      The problem is fixed by explicitly including the appropriate header.

      cfg80211: fix null pointer dereference with a custom regulatory request · 2784fe91
      Luis R. Rodriguez authored
      
      
      Once we moved the core regulatory request to the queue and let
      the scheduler process it last_request will have been left NULL
      until the schedular decides to process the first request. When
      this happens and we are loading a driver with a custom regulatory
      request like all Atheros drivers we end up with a NULL pointer
      dereference. We fix this by checking if the request was a
      custom one.

      nl80211: Add notification for dropped Deauth/Disassoc · cf4e594e
      Jouni Malinen authored
      
      
      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.
