      ath9k: Fix STA disconnect issue due to received MIC failed bcast frames · 916448e7
      Senthil Balasubramanian authored
      AR_RxKeyIdxValid will not be set for bcast/mcast frames and so relying
      this status for MIC failed frames is buggy.
      
      Due to this, MIC failure events for broadcast frames are not sent to
      supplicant resulted in AP disconnecting the STA.
      
      Able to pass Wifi Test case 5.2.18 with this fix.

      mac80211: Fix STA disconnect due to MIC failure · 8e26d5ad
      Senthil Balasubramanian authored
      Th commit titled "mac80211: clean up rx handling wrt. found_sta"
      removed found_sta variable which caused a MIC failure event
      to be reported twice for a single failure to supplicant resulted
      in STA disconnect.
      
      This should fix WPA specific countermeasures WiFi test case (5.2.17)
      issues with mac80211 based drivers which report MIC failure events in
      rx status.

      mac80211: ignore non-bcast mcast deauth/disassoc franes · 2c31333a
      Christian Lamparter authored
      This patch fixes an curious issue due to insufficient
      rx frame filtering.
      
      Saqeb Akhter reported frequent disconnects while streaming
      videos over samba: <http://marc.info/?m=128600031109136>
      > [ 1166.512087] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7)
      > [ 1526.059997] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7)
      > [ 2125.324356] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7)
      > [...]
      
      The reason is that the device generates frames with slightly
      bogus SA/TA addresses.
      
      e.g.:
       [ 2314.402316] Ignore 9f:1f:31:f8:64:ff
       [ 2314.402321] Ignore 9f:1f:31:f8:64:ff
       [ 2352.453804] Ignore 0d:1f:31:f8:64:ff
       [ 2352.453808] Ignore 0d:1f:31:f8:64:ff
       					   ^^ the group-address flag is set!
       (the correct SA/TA would be: 00:1f:31:f8:64:ff)
      
      Since the AP does not know from where the frames come, it
      generates a DEAUTH response for the (invalid) mcast address.
      This mcast deauth frame then passes through all filters and
      tricks the stack into thinking that the AP brutally kicked
      us!
      
      This patch fixes the problem by simply ignoring
      non-broadcast, group-addressed deauth/disassoc frames.
