Avinash Patil authored
This patch fixes an issue wherein association would fail on P2P interfaces. This happened because we are checking priv->mode against NL80211_IFTYPE_STATION. While this check is correct for infrastructure stations, it would fail P2P clients for which mode is NL80211_IFTYPE_P2P_CLIENT. Better check would be bss_role which has only 2 values: STA/AP.

Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following call to rt2x00queue_pause_queue() reduce to noop, i.e we do not stop queue in mac80211. To fix that introduce rt2x00queue_pause_queue_nocheck() function, which will stop queue in mac80211 directly. Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit. Note also that reordering operations i.e. first call to rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue() directly is the only available solution to fix the problem without major rework.

In certain circumstances, such as an HCI driver using __hci_cmd_sync_ev with HCI_EV_CMD_COMPLETE as the expected completion event there is the chance that hci_event_packet will call hci_req_cmd_complete twice (once for the explicitly looked after event and another time in the actual handler of cmd_complete). In the case of __hci_cmd_sync_ev this introduces a race where the first call wakes up the blocking __hci_cmd_sync_ev and lets it complete. However, by the time that a second __hci_cmd_sync_ev call is already in progress the second hci_req_cmd_complete call (from the previous operation) will wake up the blocking function prematurely and cause it to fail, as witnessed by the following log: [ 639.232195] hci_rx_work: hci0 Event packet [ 639.232201] hci_req_cmd_complete: opcode 0xfc8e status 0x00 [ 639.232205] hci_sent_cmd_data: hci0 opcode 0xfc8e [ 639.232210] hci_req_sync_complete: hci0 result 0x00 [ 639.232220] hci_cmd_complete_evt: hci0 opcode 0xfc8e [ 639.232225] hci_req_cmd_complete: opcode 0xfc8e status 0x00 [ 639.232228] __hci_cmd_sync_ev: hci0 end: err 0 [ 639.232234] __hci_cmd_sync_ev: hci0 [ 639.232238] hci_req_add_ev: hci0 opcode 0xfc8e plen 250 [ 639.232242] hci_prepare_cmd: skb len 253 [ 639.232246] hci_req_run: length 1 [ 639.232250] hci_sent_cmd_data: hci0 opcode 0xfc8e [ 639.232255] hci_req_sync_complete: hci0 result 0x00 [ 639.232266] hci_cmd_work: hci0 cmd_cnt 1 cmd queued 1 [ 639.232271] __hci_cmd_sync_ev: hci0 end: err 0 [ 639.232276] Bluetooth: hci0 sending Intel patch command (0xfc8e) failed (-61) Signed-off-by:

Unfortunately, the firmware only supports replay counters for a single GTK in D3, so that we should only upload the last key and use its replay counters. Since mac80211 key iteration will walk through the keys in order of their addition, simply use the same HW key index (1) for all GTKs, thus overwriting previous ones with newer ones. The replay counters for it are already used. Reviewed-by:

In monitor mode, priv->vif is NULL, but at one point in the receive path we blindly attempt to dereference it. Add a test to prevent this. Signed-off-by:

Currently ath9k_htc will reboot firmware only if interface was ever started. Which lead to the problem in case where interface was never started but module need to be reloaded. This patch will partially fix bug "ath9k_htc: Target is unresponsive" https://github.com/qca/open-ath9k-htc-firmware/issues/1 Reproduction case: - plug adapter - make sure nothing will touch it. Stop Networkmanager or blacklist mac address of this adapter. - rmmod ath9k_htc; sleep 1; modprobe ath9k_htc Signed-off-by:

Currently we configure harwdare and clock, only after interface start. In this case, if we reload module or reboot PC without configuring adapter, firmware will freeze. There is no software way to reset adpter. This patch add initial configuration and set it in disabled state, to avoid this freeze. Behaviour of this patch should be similar to: ifconfig wlan0 up; ifconfig wlan0 down. Bug: https://github.com/qca/open-ath9k-htc-firmware/issues/1Tested-by:

During tear down (e.g. mwifiex_sdio_remove during system suspend), mwifiex left IRQs enabled for a significant period of time when it was unable to handle them correctly. This caused interrupt storms and interfered with the bluetooth interface on the same SDIO card. Solve this by disabling interrupts at the point when they can no longer be handled correctly, which is at the start of mwifiex_remove_card(). For cleanliness, we now enable interrupts in the mwifiex_add_card() path, to be symmetrical with the disabling of interrupts. We also couple the registration of the sdio IRQ handler with the actual enable/disable of interrupts at the hardware level. I also removed a write to this register in mwifiex_init_sdio which seemed pointless and won't cause any ill effects now that we only register the SDIO IRQ handler when we are ready to accept interrupts. Includes some corrections from Amitkumar Karwar. Signed-off-by:

This patch is intended to avoid the buffering to non-assoc mesh STA and also to avoid the triggering of frame to non-assoc mesh STA which could cause kernel panic in specific hw. One of the examples, is kernel panic happens to ath9k if user space inserts the mesh STA and not proceed with the SAE and AMPE, and later the same mesh STA is detected again. The sta_state of the mesh STA remains at IEEE80211_STA_NONE and if the ieee80211_sta_ps_deliver_wakeup is called and subsequently the ath_tx_aggr_wakeup, the kernel panic due to ath_tx_node_init is not called before to initialize the require data structures. This issue is reported by Cedric Voncken before. http://www.spinics.net/lists/linux-wireless/msg106342.html [<831ea6b4>] ath_tx_aggr_wakeup+0x44/0xcc [ath9k] [<83084214>] ieee80211_sta_ps_deliver_wakeup+0xb8/0x208 [mac80211] [<830b9824>] ieee80211_mps_sta_status_update+0x94/0x108 [mac80211] [<83099398>] ieee80211_sta_ps_transition+0xc94/0x34d8 [mac80211] [<8022399c>] nf_iterate+0x98/0x104 [<8309bb60>] ieee80211_sta_ps_transition+0x345c/0x34d8 [mac80211] Signed-off-by:
