      wcn36xx: Check DXE IRQ reason · 6767b302
      Ramon Fried authored
      IRQ reason was not cheked for errors.
      Although error handing is not currently supported, it
      will be nice to output an error value to the log if the
      DMA operation failed.

      wcn36xx: calculate DXE default channel values · e5d04670
      Ramon Fried authored
      DXE channel defaults used hardcoded magic values.
      Added bit definitions of the control register and
      calculate this values in compilation for clarity.

      ath10k: Fix kernel panic while using worker (ath10k_sta_rc_update_wk) · 8b2d93dd
      Karthikeyan Periyasamy authored
      When attempt to run worker (ath10k_sta_rc_update_wk) after the station object
      (ieee80211_sta) delete will trigger the kernel panic.
      
      This problem arise in AP + Mesh configuration, Where the current node AP VAP
      and neighbor node mesh VAP MAC address are same. When the current mesh node
      try to establish the mesh link with neighbor node, driver peer creation for
      the neighbor mesh node fails due to duplication MAC address. Already the AP
      VAP created with same MAC address.
      
      It is caused by the following scenario steps.
      
      Steps:
      1. In above condition, ath10k driver sta_state callback (ath10k_sta_state)
         fails to do the state change for a station from IEEE80211_STA_NOTEXIST
         to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is
         called from ieee80211_add_station() to handle the new station
         (neighbor mesh node) request from the wpa_supplicant.
      2. Concurrently ath10k receive the sta_rc_update callback notification from
         the mesh_neighbour_update() to handle the beacon frames of the above
         neighbor mesh node. since its atomic callback, ath10k driver queue the
         work (ath10k_sta_rc_update_wk) to handle rc update.
      3. Due to driver sta_state callback fails (step 1), mac80211 free the station
         object.
      4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access
         the station object which is already deleted. so it will trigger kernel
         panic.
      
      Added the peer exist check in sta_rc_update callback before queue the work.

      ath10k: fix use-after-free in ath10k_wmi_cmd_send_nowait · 9ef0f58e
      Carl Huang authored
      The skb may be freed in tx completion context before
      trace_ath10k_wmi_cmd is called. This can be easily captured when
      KASAN(Kernel Address Sanitizer) is enabled. The fix is to move
      trace_ath10k_wmi_cmd before the send operation. As the ret has no
      meaning in trace_ath10k_wmi_cmd then, so remove this parameter too.

      ath10k: add sta rx packet stats per tid · caee728a
      Vasanthakumar Thiagarajan authored
      Added per tid sta counters for the following
      
      - Total number MSDUs received from firmware
      - Number of MSDUs received with errors like decryption, crc, mic ,etc.
      - Number of MSDUs dropped in the driver
      - A-MPDU/A-MSDU subframe stats
      - Number of MSDUS passed to mac80211
      
      All stats other than A-MPDU stats are only for received data frames.
      A-MPDU stats might have stats for management frames when monitor
      interface is active where management frames are notified both in wmi
      and HTT interfaces.
      
      These per tid stats can be enabled with tid bitmask through a debugfs
      like below
      
       echo <tid_bitmask> > /sys/kernel/debug/ieee80211/phyX/ath10k/sta_tid_stats_mask
      
       tid 16 (tid_bitmask 0x10000) is used for non-qos data/management frames
      
      The stats are read from
      /sys/kernel/debug/ieee80211/phyX/netdev\:wlanX/stations/<sta_mac>/dump_tid_stats
      
      Sample output:
      
       To enable rx stats for tid 0, 5 and 6,
      
       echo 0x00000061 > /sys/kernel/debug/ieee80211/phy0/ath10k/sta_tid_stats_mask
