2025-10-23wifi: ath11k: fix peer HE MCS assignmentBaochen Qiang
In ath11k_wmi_send_peer_assoc_cmd(), peer's transmit MCS is sent to firmware as receive MCS while peer's receive MCS sent as transmit MCS, which goes against firmwire's definition. While connecting to a misbehaved AP that advertises 0xffff (meaning not supported) for 160 MHz transmit MCS map, firmware crashes due to 0xffff is assigned to he_mcs->rx_mcs_set field. Ext Tag: HE Capabilities [...] Supported HE-MCS and NSS Set [...] Rx and Tx MCS Maps 160 MHz [...] Tx HE-MCS Map 160 MHz: 0xffff Swap the assignment to fix this issue. As the HE rate control mask is meant to limit our own transmit MCS, it needs to go via he_mcs->rx_mcs_set field. With the aforementioned swapping done, change is needed as well to apply it to the peer's receive MCS.

2025-10-23wifi: ath11k: fix VHT MCS assignmentBaochen Qiang
While associating, firmware needs to know peer's receive capability to calculate its own VHT transmit MCS, currently host sends this information to firmware via mcs->rx_mcs_set field, this is wrong as firmware actually takes it from mcs->tx_mcs_set field. Till now there is no failure seen due to this, most likely because almost all peers are advertising the same capability for both transmit and receive. Swap the assignment to fix it. Besides, rate control mask is meant to limit our own transmit MCS, hence need to go via mcs->tx_mcs_set field. With the aforementioned swapping done, change is needed as well to apply it to the peer's receive capability rather than transmit capability.

2025-10-20wifi: brcmfmac: fix crash while sending Action Frames in standalone AP ModeGokul Sivakumar
Currently, whenever there is a need to transmit an Action frame, the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to firmware. The P2P interfaces were available when wpa_supplicant is managing the wlan interface. However, the P2P interfaces are not created/initialized when only hostapd is managing the wlan interface. And if hostapd receives an ANQP Query REQ Action frame even from an un-associated STA, the brcmfmac driver tries to use an uninitialized P2P vif pointer for sending the IOVAR to firmware. This NULL pointer dereferencing triggers a driver crash.

This way, even if P2P vif is not available, the IOVAR is sent to firmware on AP vif and the ANQP Query RESP Action frame is transmitted without crashing the driver. Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev() to brcmf_p2p_attach(). Because the former function would not get executed when only hostapd is managing wlan interface, and it is not safe to do reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior init_completion(). And in the brcmf_p2p_tx_action_frame() function, the condition check for P2P Presence response frame is not needed, since the wpa_supplicant is properly sending the P2P Presense Response frame on the P2P-GO vif instead of the P2P-Device vif.

While associating, firmware needs the peer's receive capability to calculate its own VHT transmit MCS. Currently, the host sends this information via mcs->rx_mcs_set field, but firmware actually reads it from mcs->tx_mcs_set field. This mismatch is incorrect. This issue has not caused failures so far because most peers advertise identical TX and RX capabilities. Fix this by assigning the value to tx_mcs_set as expected. Additionally, the rate control mask is intended to limit our transmit MCS, so it should also apply to the peer's receive capability. Update the logic accordingly.

2025-10-15wifi: ath12k: Defer vdev bring-up until CSA finalize to avoid stale beaconAditya Kumar Singh
Mac80211 schedules CSA finalize work twice during a channel switch: first during the reserved switch phase and again during the finalize phase. The beacon content is updated only during the second schedule, which occurs after the reserved switch completes. However, the ath12k driver attempts to bring up the VDEV during the channel switch callback (ath12k_mac_update_vif_chan()), which leads to premature installation of stale beacon templates before the updated content is available. This premature VDEV bring-up causes outdated beacon information to be broadcast, which can result in updated channel parameters during the transition. In MBSSID scenarios, this behavior is particularly problematic because the transmitting interface's beacon must be updated before non-transmitting interfaces are brought up. Failing to do so can lead to beacon mismatches across interfaces. Introduce a is_csa_in_progress flag to defer VDEV_UP until CSA finalize is complete. Set this flag during the channel switch callback when CSA is active. In bss_info_changed(), check this flag and issue VDEV_UP only after the beacon template has been updated. Ensure that in MBSSID cases, the transmitting interface is brought up first, followed by all non-transmitting interfaces. This ordering makes sure correct beacon propagation and avoids stale beacon installation during CSA transitions. Additionally, move the call to ath12k_mac_update_peer_puncturing_width() before VDEV bring-up during CSA handling. This ensures that the puncturing bitmap and bandwidth settings are applied before the VDEV is brought up.

2025-10-15wifi: ath12k: Fix MSDU buffer types handling in RX error pathSarika Sharma
Currently, packets received on the REO exception ring from unassociated peers are of MSDU buffer type, while the driver expects link descriptor type packets. These packets are not parsed further due to a return check on packet type in ath12k_hal_desc_reo_parse_err(), but the associated skb is not freed. This may lead to kernel crashes and buffer leaks. Hence to fix, update the RX error handler to explicitly drop MSDU buffer type packets received on the REO exception ring.

2025-10-15wifi: ath11k: restore register window after global resetBaochen Qiang
Hardware target implements an address space larger than that PCI BAR can map. In order to be able to access the whole target address space, the BAR space is split into 4 segments, of which the last 3, called windows, can be dynamically mapped to the desired area. This is achieved by updating window register with appropriate window value. Currently each time when accessing a register that beyond ATH11K_PCI_WINDOW_START, host calculates the window value and caches it after window update, this way next time when accessing a register falling in the same window, host knows that the window is already good hence no additional update needed. However this mechanism breaks after global reset is triggered in ath11k_pci_soc_global_reset(), because with global reset hardware resets window register hence the window is not properly mapped any more. Current host does nothing about this, as a result a subsequent register access may not work as expected if it falls in a window same as before. Although there is no obvious issue seen now, better to fix it to avoid future problem. The fix is done by restoring the window register after global reset.

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.

2025-10-08wifi: ath12k: Refactor data path pdev structRipan Deuri
Refactor struct ath12k_pdev_dp to encapsulate all DP related fields of radio (ar) and rely on this single pdev object in per packet DP operations to optimize cache usage. Introduce an array of RCU-protected ath12k_pdev_dp in DP device object to find DP pdev directly from the DP device object. RCU on dp_pdevs[] provides a teardown synchronization mechanism by ensuring all in-flight access to dp_pdev pointers complete before reclaim. Once a dp_pdev pointer is obtained, its internal fields can be accessed as follows: - Writers update internal fields using their own synchronization. - Readers may perform lockless reads if occasional inconsistency is acceptable, or use additional synchronization (e.g., spin_lock, atomic_t) for a coherent view between readers and writers. Please note that RCU is used for dp_pdevs[] at this stage to align with ab->pdevs_active[]. However, if the teardown paths ensure quiescence, both dp_pdevs[] and pdevs_active[] can be converted to plain pointers, removing RCU synchronization overhead. This will be evaluated separately.

2025-10-06wifi: ath11k: avoid bit operation on key flagsRameshkumar Sundaram
Bitwise operations with WMI_KEY_PAIRWISE (defined as 0) are ineffective and misleading. This results in pairwise key validations added in commit 97acb0259cc9 ("wifi: ath11k: fix group data packet drops during rekey") to always evaluate false and clear key commands for pairwise keys are not honored. Since firmware supports overwriting the new key without explicitly clearing the previous one, there is no visible impact currently. However, to restore consistency with the previous behavior and improve clarity, replace bitwise operations with direct assignments and comparisons for key flags.

2025-10-06wifi: ath12k: free skb during idr cleanup callbackKarthik M
ath12k just like ath11k [1] did not handle skb cleanup during idr cleanup callback. Both ath12k_mac_vif_txmgmt_idr_remove() and ath12k_mac_tx_mgmt_pending_free() performed idr cleanup and DMA unmapping for skb but only ath12k_mac_tx_mgmt_pending_free() freed skb. As a result, during vdev deletion a memory leak occurs. Refactor all clean up steps into a new function. New function ath12k_mac_tx_mgmt_free() creates a centralized area where idr cleanup, DMA unmapping for skb and freeing skb is performed. Utilize skb pointer given by idr_remove(), instead of passed as a function argument because IDR will be protected by locking. This will prevent concurrent modification of the same IDR. Now ath12k_mac_tx_mgmt_pending_free() and ath12k_mac_vif_txmgmt_idr_remove() call ath12k_mac_tx_mgmt_free().
