2023-10-05wifi: ath12k: fix debug messagesKalle Valo
In ath12k the debug messages were broken, no matter setting what value to the debug_mask module parameter would not get the debug messages printed. The issue is that __ath12k_dbg() uses dev_dbg() to print the debug messages which requires either enabling CONFIG_DYNAMIC_DEBUG or DEBUG symbol in the driver. ath12k is supposed to use debug_mask module to control whether debug messages are printed or not. Using both CONFIG_DYNAMIC_DEBUG and debug_mask parameter does not make any sense so switch to using dev_printk(), just like ath11k does. Now it's enough just to debug_mask module parameter to get the debug messages.

2023-10-05wifi: ath11k: fix Tx power value during active CACAditya Kumar Singh
Tx power is fetched from firmware's pdev stats. However, during active CAC, firmware does not fill the current Tx power and sends the max initialised value filled during firmware init. If host sends this power to user space, this is wrong since in certain situations, the Tx power could be greater than the max allowed by the regulatory. Hence, host should not be fetching the Tx power during an active CAC. Fix this issue by returning -EAGAIN error so that user space knows that there's no valid value available.

2023-10-05wifi: ath11k: fix CAC running state during virtual interface startAditya Kumar Singh
Currently channel definition's primary channel's DFS CAC time as well as primary channel's state i.e usable are used to set the CAC_RUNNING flag for the ath11k radio structure. However, this is wrong since certain channel definition are possbile where primary channel may not be a DFS channel but, secondary channel is a DFS channel. For example - channel 36 with 160 MHz bandwidth. In such cases, the flag will not be set which is wrong. Fix this issue by using cfg80211_chandef_dfs_usable() function from cfg80211 which return trues if at least one channel is in usable state. While at it, modify the CAC running debug log message to print the CAC time as well in milli-seconds.

2023-10-02wifi: ath10k: indicate to mac80211 scan complete with aborted flag for ↵Wen Gong
ATH10K_SCAN_STARTING state Scan failure can not be recovered from when running a loop of the following steps: 1. run scan: "iw wlan scan". 2. run command: echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash immediately after step 1. result: scan failed and can not recover even when wlan recovery succeeds: command failed: Device or resource busy (-16) reason: When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and function ath10k_hw_scan() returns, then simulate_fw_crash arrives and the scan started event does not arrive, and then it starts to do recovery of wlan. __ath10k_scan_finish() which is called from ath10k_halt() is one step of recovery, it will not call ieee80211_scan_completed() by logic currently because the scan state is ATH10K_SCAN_STARTING. Thus it leads the scan not being completed in mac80211, and leads all consecutive scans failing with -EBUSY in nl80211_trigger_scan even after wlan recovery success. Indicate scan complete with aborted flag to mac80211 for ATH10K_SCAN_STARTING to allow recovery from scan failed with "Device or resource busy (-16)" after wlan recovery.

At the time of the writing, the value of 'num_radar_types' is 7 or 9. So on a 64 bits system, only 56 or 72 bytes are allocated for the 'detectors' array.

2023-10-02wifi: ath10k: Don't touch the CE interrupt registers after power upDouglas Anderson
As talked about in commit d66d24ac300c ("ath10k: Keep track of which interrupts fired, don't poll them"), if we access the copy engine register at a bad time then ath10k can go boom. However, it's not necessarily easy to know when it's safe to access them. The ChromeOS test labs saw a crash that looked like this at shutdown/reboot time (on a chromeos-5.15 kernel, but likely the problem could also reproduce upstream): Internal error: synchronous external abort: 96000010 [#1] PREEMPT SMP ...

Let's fix this by changing how we "disable" the interrupts. Instead of tweaking the copy engine registers we'll just use disable_irq() and enable_irq(). Then we'll configure the interrupts once at power up time.

2023-10-02wifi: ath12k: add keep backward compatibility of PHY mode to avoid firmware ↵Wen Gong
crash In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has been disabled for size reduction. Currently ath12k always enables EHT PHY mode during vdev start but with the special firmware that will cause a firmware crash during vdev start in firmware initialisation. This is because the firmware will use the EHT mode to allocate resources but as the EHT mode is not available in the firmware, there's an internal conflict and the firmware will crash. To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware supports EHT. If EHT is not supported downgrade the PHY mode to HE (IEEE 802.11ax). This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled for QCN9274, then eht_cap->has_eht will always set for it, and the logic of this patch will not take effect and the PHY mode will not down grade for it.

2023-10-02wifi: ath12k: do not drop data frames from unassociated stationsHari Chandrakanthan
>From 'IEEE Std 802.11-2020 section 11.3.4.1': If STA A in an infrastructure BSS receives a Class 2 or Class 3 frame from STA B that is not authenticated with STA A (i.e., the state for STA B is State 1), STA A shall discard the frame. If the frame has an individual address in the Address 1 field, the MLME of STA A shall send a Deauthentication frame to STA B. When data frames from unassociated stations are received by an AP, the AP is supposed to send a deauthentication/disassociation frame with reason code "Class 2 frame received from nonauthenticated STA" or "Class 3 frame received from nonassociated STA". But ath12k AP doesn't send deauthentication/disassociation frames, when it receives data frames from unassociated stations. The ath12k driver drops the data frames from unassociated station and the upper layer(mac80211/hostapd) is not aware of such event. Hence deauthentication/disassociation frame is not sent to that particular station by the AP. To address this issue, allow the data frames from the unassociated stations to reach mac80211 so that mac80211 can send NL80211_CMD_UNEXPECTED_FRAME event to userspace(hostapd) and hostapd upon receiving the event will send the deauthentication/disassociation frame with proper reason code. The data frame from unassociated stations gets dropped in mac80211.

The two cases would expect to operate the channel to which they want. However, during MCC, channels are scheduled by FW MCC state mechanism. So, channels cannot be controlled explicitly.

Under TDMA-based MCC (multi-channel concurrency), there are two roles, reference and auxiliary. We arrange MCC timeline based on time domain of reference role. Then, we calculate NoA start time according to MCC timeline. Besides, when MCC runs GO+STA mode, we plan an offset between GO time domain and STA time domain to make their TBTTs have a time gap. However, if GO is auxiliary role instead of reference role, NoA start time is described by STA time domain instead of GO time domain. To fix this, we apply the offset mentioned above to NoA start time to convert time domain from STA to GO.

2023-09-28wifi: ath12k: call ath12k_mac_fils_discovery() without conditionAloka Dixit
Mac80211 does not set flags BSS_CHANGED_FILS_DISCOVERY and BSS_CHANGED_UNSOL_BCAST_PROBE_RESP if there are no updates to FILS discovery and unsolicited broadcast probe response transmission configurations respectively. For BSS change operations such as channel switch, this results in the transmissions getting stopped because the driver does not send WMI command to firmware if the flags are not set.

2023-09-28wifi: ath12k: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850Wen Gong
Currently mac80211 will send 3 scan request for each scan of WCN7850, they are 2.4 GHz/5 GHz/6 GHz band scan. Firmware of WCN7850 will cache the RNR IE(Reduced Neighbor Report element) which exist in the beacon of 2.4 GHz/5 GHz of the AP which is co-located with 6 GHz, and then use the cache to scan in 6 GHz band scan if the 6 GHz scan is in the same scan with the 2.4 GHz/5 GHz band, this will helpful to search more AP of 6 GHz. Also it will decrease the time cost of scan because firmware will use dual-band scan for the 2.4 GHz/5 GHz, it means the 2.4 GHz and 5 GHz scans are doing simultaneously. Set the flag IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850 since it supports 2.4 GHz/5 GHz/6 GHz in a single wiphy/ieee80211_hw. This does not impact QCN9274, because it is not single_phy, so does not have 2.4 GHz/5 GHz/6 GHz in the same wiphy, then it does not match the condition and then IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS will not set for QCN9274.

ath12k prints "Received scan event for unknown vdev" when doing the following test: 1. trigger scan 2. wait 0.2 second 3. iw reg set is issued or 11d scan complete event is sent from firmware Reason is: When iw reg set is issues or the 11d scan complete event is received, the new country code will be set to the firmware, and the new regdomain info indicated to ath12k, then the new channel list will be sent to the firmware. The firmware will cancel the current scan after receiving WMI_SCAN_CHAN_LIST_CMDID which is used for the new channel list, and the state of ath12k is ATH12K_SCAN_RUNNING, then ath12k_get_ar_on_scan_abort() returns NULL and ath12k_scan_event() returns at this point and does not indicate scan completion to mac80211. Indicate scan completion to mac80211 and get rid of the "Received scan event for unknown vdev" print for the above case.

2023-09-28wifi: ath12k: indicate to mac80211 scan complete with aborted flag for ↵Wen Gong
ATH12K_SCAN_STARTING state Scan failure can not be recovered from when running a loop of the following steps: 1. run scan: "iw wlan scan". 2. run command: echo assert > /sys/kernel/debug/ath12k/wcn7850\ hw2.0/simulate_fw_crash immediately after step 1. result: scan failed and can not recover even when wlan recovery succeeds: command failed: Device or resource busy (-16) reason: When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and function ath12k_mac_op_hw_scan() returns, then simulate_fw_crash arrives and the scan started event does not arrive, and then it starts to do recovery of wlan. __ath12k_mac_scan_finish() which is called from ath12k_core_halt() is one step of recovery, it will not call ieee80211_scan_completed() by logic currently because the scan state is ATH12K_SCAN_STARTING. Thus it leads the scan not being completed in mac80211, and leads all consecutive scans failing with -EBUSY in nl80211_trigger_scan even after wlan recovery success. Indicate scan complete with aborted flag to mac80211 for ATH12K_SCAN_STARTING to allow recovery from scan failed with "Device or resource busy (-16)" after wlan recovery.

2023-09-28wifi: ath12k: fix recovery fail while firmware crash when doing channel switchWen Gong
When firmware crashed while channel switch running, recovery starts in ath12k. Then ieee80211_sta_connection_lost() will be called by function ieee80211_restart_work() in mac80211. And then many WMI command timeout because firmware is crashed. Each WMI command cost 3 seconds, then the total time will be large and leads recovery fail. Hence change to set value ATH12K_FLAG_CRASH_FLUSH early and then ath12k_wmi_cmd_send() will not wait 3 seconds, then recovery will be started quickly and success.

2023-09-28wifi: ath12k: add support for hardware rfkill for WCN7850Lingbo Kong
When hardware rfkill is enabled in the firmware, it will report the capability using WMI_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY event to the host. Currently ath12k does not process this service capability. In order to support this, update ath12k to check if the capability is enabled, if so, send the GPIO information to firmware. When the firmware detects hardware rfkill is enabled by the user, it will report it using WMI_RFKILL_STATE_CHANGE_EVENTID. When ath12k receive the event, it will set the value of rfkill_radio_on based on whether radio_state is equal to WMI_RFKILL_RADIO_STATE_ON, then send WMI_PDEV_PARAM_RFKILL_ENABLE to firmware.
