2025-10-15wifi: ath10k: move recovery check logic into a new workKang Yang
Currently, ath10k has a recovery check logic. It will wait for the last recovery to finish by wait_for_completion_timeout(); But in SDIO scenarios, the recovery function may be invoked from interrupt context, where long blocking waits are undesirable and can lead to system instability. Additionally, Linux’s ordered workqueue processes one task at a time. If a previous recovery is still queued or executing, new triggers are ignored. This prevents accurate tracking of consecutive failures and delays transition to the WEDGED state. To address this, move the recovery check logic into a different workqueue.

It appears that not all hardware/firmware implementations support group key deletion correctly, which can lead to connection hangs and deauthentication following GTK rekeying (delete and install). To avoid this issue, instead of attempting to delete the key using the special WMI_CIPHER_NONE value, we now replace the key with an invalid (random) value. This behavior has been observed with WCN39xx chipsets.

2025-09-18wifi: ath10k: avoid unnecessary wait for service ready messageBaochen Qiang
Commit e57b7d62a1b2 ("wifi: ath10k: poll service ready message before failing") works around the failure in waiting for the service ready message by active polling. Note the polling is triggered after initial wait timeout, which means that the wait-till-timeout can not be avoided even the message is ready. A possible fix is to do polling once before wait as well, however this can not handle the race that the message arrives right after polling. So the solution is to do periodic polling until timeout.

2025-09-18wifi: ath: Use of_reserved_mem_region_to_resource() for "memory-region"Rob Herring (Arm)
Use the newly added of_reserved_mem_region_to_resource() function to handle "memory-region" properties. The error handling is a bit different for ath10k. "memory-region" is optional, so failed lookup is not an error. But then an error in of_address_to_resource() is treated as an error. However, that distinction is not really important. Either the region is available and usable or it is not. So now, it is just of_reserved_mem_region_to_resource() which is checked for an error.

In rare cases, ath10k may lose connection with the PCIe bus due to some unknown reasons, which could further lead to system crashes during resuming due to watchdog timeout: ath10k_pci 0000:01:00.0: wmi command 20486 timeout, restarting hardware ath10k_pci 0000:01:00.0: already restarting ath10k_pci 0000:01:00.0: failed to stop WMI vdev 0: -11 ath10k_pci 0000:01:00.0: failed to stop vdev 0: -11 ieee80211 phy0: PM: **** DPM device timeout **** Call Trace: panic+0x125/0x315 dpm_watchdog_set+0x54/0x54 dpm_watchdog_handler+0x57/0x57 call_timer_fn+0x31/0x13c At this point, all WMI commands will timeout and attempt to restart device. So set a threshold for consecutive restart failures. If the threshold is exceeded, consider the hardware is unreliable and all ath10k operations should be skipped to avoid system crash. fail_cont_count and pending_recovery are atomic variables, and do not involve complex conditional logic. Therefore, even if recovery check and reconfig complete are executed concurrently, the recovery mechanism will not be broken.

2025-06-24wifi: cfg80211/mac80211: Add support to get radio indexRoopni Devanathan
Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.

2025-06-07wifi: ath10k: Avoid vdev delete timeout when firmware is already downLoic Poulain
In some scenarios, the firmware may be stopped before the interface is removed, either due to a crash or because the remoteproc (e.g., MPSS) is shut down early during system reboot or shutdown. This leads to a delay during interface teardown, as the driver waits for a vdev delete response that never arrives, eventually timing out. Example (SNOC): $ echo stop > /sys/class/remoteproc/remoteproc0/state [ 71.64] remoteproc remoteproc0: stopped remote processor modem $ reboot [ 74.84] ath10k_snoc c800000.wifi: failed to transmit packet, dropping: -108 [ 74.84] ath10k_snoc c800000.wifi: failed to submit frame: -108 [...] [ 82.39] ath10k_snoc c800000.wifi: Timeout in receiving vdev delete response To avoid this, skip waiting for the vdev delete response if the firmware is already marked as unreachable (`ATH10K_FLAG_CRASH_FLUSH`), similar to how `ath10k_mac_wait_tx_complete()` and `ath10k_vdev_setup_sync()` handle this case.

2025-06-07ath10k: snoc: fix unbalanced IRQ enable in crash recoveryCaleb Connolly
In ath10k_snoc_hif_stop() we skip disabling the IRQs in the crash recovery flow, but we still unconditionally call enable again in ath10k_snoc_hif_start(). We can't check the ATH10K_FLAG_CRASH_FLUSH bit since it is cleared before hif_start() is called, so instead check the ATH10K_SNOC_FLAG_RECOVERY flag and skip enabling the IRQs during crash recovery. This fixes unbalanced IRQ enable splats that happen after recovering from a crash.

2025-04-17wifi: ath10k: Don't use %pK through printkThomas Weißschuh
In the past %pK was preferable to %p as it would not leak raw pointer values into the kernel log. Since commit ad67b74d2469 ("printk: hash addresses printed with %p") the regular %p has been improved to avoid this issue. Furthermore, restricted pointers ("%pK") were never meant to be used through printk(). They can still unintentionally leak raw pointers or acquire sleeping looks in atomic contexts. Switch to the regular pointer formatting which is safer and easier to reason about. There are still a few users of %pK left, but these use it through seq_file, for which its usage is safe.

2024-11-11wifi: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/net/wireless to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. En passant several whitespace changes are done to make indentation consistent in the struct initializers.

The software rate control still doesn't support it, but that'll be skipped by not having a rate control ref. Since it now operates on a link sta, rename the driver method.

2024-10-16wifi: ath10k: avoid NULL pointer error during sdio removeKang Yang
When running 'rmmod ath10k', ath10k_sdio_remove() will free sdio workqueue by destroy_workqueue(). But if CONFIG_INIT_ON_FREE_DEFAULT_ON is set to yes, kernel panic will happen: Call trace: destroy_workqueue+0x1c/0x258 ath10k_sdio_remove+0x84/0x94 sdio_bus_remove+0x50/0x16c device_release_driver_internal+0x188/0x25c device_driver_detach+0x20/0x2c This is because during 'rmmod ath10k', ath10k_sdio_remove() will call ath10k_core_destroy() before destroy_workqueue(). wiphy_dev_release() will finally be called in ath10k_core_destroy(). This function will free struct cfg80211_registered_device *rdev and all its members, including wiphy, dev and the pointer of sdio workqueue. Then the pointer of sdio workqueue will be set to NULL due to CONFIG_INIT_ON_FREE_DEFAULT_ON. After device release, destroy_workqueue() will use NULL pointer then the kernel panic happen. Call trace: ath10k_sdio_remove ->ath10k_core_unregister …… ->ath10k_core_stop ->ath10k_hif_stop ->ath10k_sdio_irq_disable ->ath10k_hif_power_down ->del_timer_sync(&ar_sdio->sleep_timer) ->ath10k_core_destroy ->ath10k_mac_destroy ->ieee80211_free_hw ->wiphy_free …… ->wiphy_dev_release ->destroy_workqueue Need to call destroy_workqueue() before ath10k_core_destroy(), free the work queue buffer first and then free pointer of work queue by ath10k_core_destroy(). This order matches the error path order in ath10k_sdio_probe(). No work will be queued on sdio workqueue between it is destroyed and ath10k_core_destroy() is called. Based on the call_stack above, the reason is: Only ath10k_sdio_sleep_timer_handler(), ath10k_sdio_hif_tx_sg() and ath10k_sdio_irq_disable() will queue work on sdio workqueue. Sleep timer will be deleted before ath10k_core_destroy() in ath10k_hif_power_down(). ath10k_sdio_irq_disable() only be called in ath10k_hif_stop(). ath10k_core_unregister() will call ath10k_hif_power_down() to stop hif bus, so ath10k_sdio_hif_tx_sg() won't be called anymore.

2024-09-06wifi: mac80211: handle ieee80211_radar_detected() for MLOAditya Kumar Singh
Currently DFS works under assumption there could be only one channel context in the hardware. Hence, drivers just calls the function ieee80211_radar_detected() passing the hardware structure. However, with MLO, this obviously will not work since number of channel contexts will be more than one and hence drivers would need to pass the channel information as well on which the radar is detected. Also, when radar is detected in one of the links, other link's CAC should not be cancelled. Hence, in order to support DFS with MLO, do the following changes - * Add channel context conf pointer as an argument to the function ieee80211_radar_detected(). During MLO, drivers would have to pass on which channel context conf radar is detected. Otherwise, drivers could just pass NULL. * ieee80211_radar_detected() will iterate over all channel contexts present and * if channel context conf is passed, only mark that as radar detected * if NULL is passed, then mark all channel contexts as radar detected * Then as usual, schedule the radar detected work. * In the worker, go over all the contexts again and for all such context which is marked with radar detected, cancel the ongoing CAC by calling ieee80211_dfs_cac_cancel() and then notify cfg80211 via cfg80211_radar_event(). * To cancel the CAC, pass the channel context as well where radar is detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is canceled only on the links using the provided context, leaving other links unaffected. This would also help in scenarios where there is split phy 5 GHz radio, which is capable of DFS channels in both lower and upper band. In this case, simultaneous radars can be detected.
