kzalloc() is used to allocate memory for cd->detectors, and if it fails, channel_detector_exit() behind the label fail will be called: channel_detector_exit(dpd, cd); In channel_detector_exit(), cd->detectors is dereferenced through: struct pri_detector *de = cd->detectors[i]; To fix this possible null-pointer dereference, check cd->detectors before the for loop to dereference cd->detectors.

This replaces the existing .txt binding file. Furthermore, this also helps with validating DTS files. Introduced binding changes: 1. added inherited mac-address nvmem property 2. added inherited ieee80211-freq-limit property 3. added new calibration nvmem property 4. added second example (taken from the Netgear WNDR3700v2) Reason: Setting qca,no-eeprom; takes presedence over nvmem-cells. I think a different example is needed, because the driver can only reads from one calibration source per device. 5.

In tests with two Lima boards from 8devices (QCA4531 based) on OpenWrt 19.07 we could force a silent restart of a device with no serial output when we were sending a high amount of UDP traffic (iperf3 at 80 MBit/s in both directions from external hosts, saturating the wifi and causing a load of about 4.5 to 6) and were then triggering an ath9k_queue_reset(). Further debugging showed that the restart was caused by the ath79 watchdog. With disabled watchdog we could observe that the device was constantly going into ath_isr() interrupt handler and was returning early after the ATH_OP_HW_RESET flag test, without clearing any interrupts. Even though ath9k_queue_reset() calls ath9k_hw_kill_interrupts(). With JTAG we could observe the following race condition: 1) ath9k_queue_reset() ... -> ath9k_hw_kill_interrupts() -> set_bit(ATH_OP_HW_RESET, &common->op_flags); ... <- returns 2) ath9k_tasklet() ... -> ath9k_hw_resume_interrupts() ... <- returns 3) loops around: ... handle_int() -> ath_isr() ... -> if (test_bit(ATH_OP_HW_RESET, &common->op_flags)) return IRQ_HANDLED; x) ath_reset_internal(): => never reached <= And in ath_isr() we would typically see the following interrupts / interrupt causes: * status: 0x00111030 or 0x00110030 * async_cause: 2 (AR_INTR_MAC_IPQ) * sync_cause: 0 So the ath9k_tasklet() reenables the ath9k interrupts through ath9k_hw_resume_interrupts() which ath9k_queue_reset() had just disabled. And ath_isr() then keeps firing because it returns IRQ_HANDLED without actually clearing the interrupt. To fix this IRQ storm also clear/disable the interrupts again when we are in reset state.

Sometimes, in yet unknown cases the wifi chip stops working. To allow a watchdog in userspace to easily and quickly reset the wifi chip, add the according functionality to userspace. A reset can then be triggered via: $ echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/reset The number of user resets can further be tracked in the row "User reset" in the same file. So far people usually used "iw scan" to fix ath9k chip hangs from userspace. Which triggers the ath9k_queue_reset(), too. The reset file however has the advantage of less overhead, which makes debugging bugs within ath9k_queue_reset() easier. Signed-off-by:

When rebooting on sc7180 Trogdor devices I see the following crash from the wifi driver. ath10k_snoc 18800000.wifi: firmware crashed! (guid 83493570-29a2-4e98-a83e-70048c47669c) This is because a modem stop event looks just like a firmware crash to the driver, the qmi connection is closed in both cases. Use the qcom ssr notifier block to stop treating the qmi connection close event as a firmware crash signal when the modem hasn't actually crashed. See ath10k_qmi_event_server_exit() for more details. This silences the crash message seen during every reboot.

According to the Realtek propritary driver and the rtw88 driver, the tx rates of the ack (includes block ack) are initialized with lower tx rates (no HT rates) which is set by the RRSR register value. In real cases, ack rate higher than current tx rate could lead to difficulty for the receiving end to receive management/control frames. The retransmission rate would be higher then expected when the driver is acting as receiver and the RSSI is not good. Cross out higer rates for ack packet before implementing dynamic rrsr configuration like the commit 48308726 ("rtw88: add dynamic rrsr configuration"). Signed-off-by:

The usage of fw_crash debugfs is to write 1 to it to trigger fw crash simulation and to read from it to check the state. When zero is read, it is supposed to mean fw crash/restart process is done. Then, some test plans can be designed for crash/restart. e.g. step 1. trigger fw crash simulation step 2. poll the state until zero is read step 3. check connection by ping test However, in certain connection cases, triggering fw crash simulation will take a while. If the state is queried too early before restart begins processing, it may mistakenly think restart process has been done. If some tests are started at this time, something unexpected might happen due to the follow-up restart process. To avoid that, let fw_crash also show non-zero when a simulation is still triggering.

For fragmented packets, ath11k reassembles each fragment as a normal packet and then reinjects it into HW ring. In this case, the DMA direction should be DMA_TO_DEVICE, not DMA_FROM_DEVICE, otherwise invalid payload will be reinjected to HW and then delivered to host. What is more, since arbitrary memory could be allocated to the frame, we don't know what kind of data is contained in the buffer reinjected. Thus, as a bad result, private info may be leaked.

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/ath11k/qca6490\ 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 ath11k_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. __ath11k_mac_scan_finish() which is called from ath11k_core_halt() is one step of recovery, it will not call ieee80211_scan_completed() by logic currently because the scan state is ATH11K_SCAN_STARTING.

When wlan interface is up, 11d scan is sent to the firmware, and the firmware needs to spend couple of seconds to complete the 11d scan. If immediately a normal scan from user space arrives to ath11k, then the normal scan request is also sent to the firmware, but the scan started event will be reported to ath11k until the 11d scan complete. When timed out for the scan started in ath11k, ath11k stops the normal scan and the firmware reports WMI_SCAN_EVENT_DEQUEUED to ath11k for the normal scan. ath11k has no handler for the event and then timed out for the scan completed in ath11k_scan_stop(), and ath11k prints the following error message.

To support the HTT Stats DebugFS interface a single large buffer that contains the stats must be provided to the DebugFS infrastructure. In the current code, for each class of stats, the stats are first formatted in a local on-stack buffer, and then the local buffer is copied to the large DebugFS buffer. This logic has a problem when, for a given class, the formatted stats exceed the size of the on-stack buffer. When this occurs the stats for this class is truncated. In addition, this logic is inefficient since it introduces an unnecessary memory copy. To address these issues, update the logic to no longer use a local on-stack buffer, and instead write the formatted data directly into the large DebugFS buffer.

However at that time those registers are not accessible due to reset, thus they are actually not cleared at all. For WCN6855, it may cause target fail to initialize.

For some chips such as WCN6855, single_pdev_only is set in struct ath11k_hw_params which means ath11k calls ieee80211_register_hw() only once and create only one device interface, and that device interface supports all 2G/5G/6G channels. ath11k_mac_setup_channels_rates() sets up the channels and it is called for each device interface. It is called only once for single_pdev_only, and then set up all channels for 2G/5G/6G. The logic of ath11k_mac_setup_channels_rates() is not suitable for single_pdev_only, it leads to all 6G channels being disabled for the device interface which is single_pdev_only such as WCN6855. Add channel frequency checks for the 6G band and enable the 6G channels properly based on what is supported by the chip.

WCN6855 uses single_pdev_only, so it supports both the 5G and 6G bands in the same ath11k/pdev and it needs to enable ht_cap/vht_cap for the 5G band, otherwise it will downgrade to non-HT mode for the 5G band. Some chips like QCN9074 only support the 6G band, not the 5G band, and use the flag ar->supports_6ghz which is true to discard ht_cap/vht_cap.

Add WMI_PEER_CREATE_CONF_EVENTID in wmi_tlv_event_id and handle the same as unsupported event id under wmi logs. warning prints: [ 4382.230817] ath11k_pci 0000:01:00.0: Unknown eventid: 0x601a Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01695-QCAHKSWPL_SILICONZ-1 Signed-off-by:
