2025-04-07wifi: ath12k: Fix memory corruption during MLO multicast txP Praneesh
The struct sk_buff's control buffer is shared by mac80211's struct ieee80211_tx_info and ath12k's struct ath12k_skb_cb. When the driver wants to transmit an skb, it caches all the mac80211-specific information from struct ieee80211_tx_info, then performs a memset on the control buffer before writing the ath12k-specific information using struct ath12k_skb_cb. However, during multicast tx, the key is being filled into the driver data, which overwrites some crucial members like link_id and flags in struct ath12k_skb_cb. This causes invalid information retrieval when the driver accesses these fields during ath12k_dp_tx(). Fix this issue by removing the key filling logic during MLO multicast tx, as it is not used anywhere in the tx path.

2025-04-07wifi: ath12k: Fix memory leak during vdev_id mismatchP Praneesh
Currently driver enables vdev_id check as part of the bank configuration in ath12k_dp_tx_get_vdev_bank_config(). This check ensures that the vdev_id configured in the bank register aligns with the vdev_id in the packet's address search table within the firmware. If there is a mismatch, the firmware forwards the packet with the HTT status HAL_WBM_REL_HTT_TX_COMP_STATUS_VDEVID_MISMATCH. Since driver does not handle this vdev_id mismatch HTT status, the corresponding buffers are not freed properly, causing a memory leak. Fix this issue by adding handling to free the buffers when a vdev_id mismatch HTT status is encountered.

2025-04-07wifi: ath12k: Fix incorrect rates sent to firmwarePradeep Kumar Chitrapu
Before firmware assert, if there is a station interface in the device which is not associated with an AP, the basic rates are set to zero. Following this, during firmware recovery, when basic rates are zero, ath12k driver is sending invalid rate codes, which are negative values, to firmware. This results in firmware assert. Fix this by checking if rate codes are valid, before sending them to the firmware.

Currently ath12k does not send the country code to firmware after device recovery. As a result the country code will be the default one which is reported from firmware.

2025-04-02wifi: ath12k: add 11d scan offload supportWen Gong
The flow of 11d scan is: 1. trigger 11d scan. 2. receive, parse, and update 11d scan result. 3. stop 11d scan. So need to add handler for WMI_11D_SCAN_START_CMDID and WMI_11D_SCAN_STOP_CMDID to trigger/stop 11d scan. Add process of WMI event WMI_11D_NEW_COUNTRY_EVENTID for 11d scan result. There are two points that need to be noted: 1. The 11d scan priority is 'MEDIUM' in firmware, the hw scan priority is 'LOW'. When 11d scan is running, hw scan will be canceled. To avoid this, change the hw scan priority to 'MEDIUM' when 11d scan is running. 2. Need to add wait_for_completion_timeout() for scan.complete in ath12k_reg_update_chan_list() because 11d scan will cost more than 5 seconds. Due to another existing wait in ath12k_scan_stop(), there will be two scan.complete in different threads. Therefore use complete_all() instead of complete() for scan.complete. complete_all() can work well when it is only one thread wait for scan.complete.

When userspace tries to set country code by NL80211_REGDOM_SET_BY_USER hint(like iw reg set XX), it will pass new country code to ath12k. Then ath12k will set this new country code to firmware by WMI_SET_INIT_COUNTRY_CMDID. For AP based chips(QCN92xx), WMI_SET_INIT_COUNTRY_CMDID is the correct command. However, for STATION based chips(WCN7850), it need to use WMI_SET_CURRENT_COUNTRY_CMDID. Add flag current_cc_support in hardware parameters. It is used to distinguish AP/STA platform. After that, the firmware will work normally and the regulatory feature works well for WCN7850.

2025-04-02wifi: ath12k: Fix memory leak due to multiple rx_stats allocationSidhanta Sahu
rx_stats for each arsta is allocated when adding a station. arsta->rx_stats will be freed when a station is removed. Redundant allocations are occurring when the same station is added multiple times. This causes ath12k_mac_station_add() to be called multiple times, and rx_stats is allocated each time. As a result there is memory leaks. Prevent multiple allocations of rx_stats when ath12k_mac_station_add() is called repeatedly by checking if rx_stats is already allocated before allocating again. Allocate arsta->rx_stats if arsta->rx_stats is NULL respectively.

Extend the DMA mask to 36 bits to avoid using bounce buffers on machines without an iommu (under OS control) similar to what was done for ath11k in commit dbd73acb22d8 ("wifi: ath11k: enable 36 bit mask for stream DMA"). This specifically avoids using bounce buffers on Qualcomm Snapdragon X Elite machines like the Lenovo ThinkPad T14s when running at EL1. Note that the mask could possibly be extended further but unresolved DMA issues with 64 GiB X Elite machines currently prevents that from being tested. Also note that the driver is limited to 32 bits for coherent allocations and that there is no need to check for errors when setting masks larger than 32 bits.

2025-03-17wifi: ath12k: add get_txpower mac opsAditya Kumar Singh
Driver does not support get_txpower mac ops because of which cfg80211 returns vif->bss_conf.txpower to user space. bss_conf.txpower gets its value from ieee80211_channel->max_reg_power. However, the final txpower is dependent on few other parameters apart from max regulatory supported power. It is the firmware which knows about all these parameters and considers the minimum for each packet transmission. All ath12k firmware reports the final TX power in firmware pdev stats which falls under fw_stats. add get_txpower mac ops to get the TX power from firmware leveraging fw_stats and return it accordingly. While at it, there is a possibility that repeated stats request WMI commands are queued to FW if mac80211/userspace does get tx power back to back(in Multiple BSS cases). This could potentially consume the WMI queue completely. Hence limit this by fetching the power only for every 5 seconds and reusing the value until the refresh timeout or when there is a change in channel. Also remove init_completion(&ar->fw_stats_complete) in ath12k_mac_hw_register() as ath12k_fw_stats_init() takes care of it for each ar.

In case of mesh this invalid tx status report might trigger mpath broken issue due to increase in mpath fail average.

2025-02-28wifi: ath12k: pass tx arvif for MBSSID and EMA beacon generationAloka Dixit
Add new input parameter to ath12k_mac_setup_bcn_tmpl_ema() for 'tx_arvif' as the caller ath12k_mac_setup_bcn_tmpl() already stores it locally. Avoid duplicate retrieval.

2025-02-28wifi: ath12k: refactor transmitted arvif retrievalAloka Dixit
Create a new function ath12k_mac_get_tx_arvif() to retrieve 'arvif' for the transmitted interface of the MBSSID set. This clean up will help modifying the same code path for MLO changes.

2025-02-27wifi: ath11k/ath12k: Replace irq_set_affinity_hint() with ↵Manivannan Sadhasivam
irq_set_affinity_and_hint() irq_set_affinity_hint() API is deprecated now, so let's use the recommended equivalent irq_set_affinity_and_hint(). Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-05266-QCAHSTSWPLZ_V2_TO_X86-1 Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Link: https://patch.msgid.link/20250225053447.16824-4-manivannan.sadhasivam@linaro.org Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>
2025-02-27wifi: ath12k: Clear affinity hint before calling ath12k_pci_free_irq() in ↵Manivannan Sadhasivam
error path If a shared IRQ is used by the driver due to platform limitation, then the IRQ affinity hint is set right after the allocation of IRQ vectors in ath12k_pci_msi_alloc(). This does no harm unless one of the functions requesting the IRQ fails and attempt to free the IRQ. This may end up with a warning from the IRQ core that is expecting the affinity hint to be cleared before freeing the IRQ: kernel/irq/manage.c: /* make sure affinity_hint is cleaned up */ if (WARN_ON_ONCE(desc->affinity_hint)) desc->affinity_hint = NULL; So to fix this issue, clear the IRQ affinity hint before calling ath12k_pci_free_irq() in the error path. The affinity will be cleared once again further down the error path due to code organization, but that does no harm.
