9 dayswifi: ath12k: Correct tid cleanup when tid setup failsSarika Sharma
Currently, if any error occurs during ath12k_dp_rx_peer_tid_setup(), the tid value is already incremented, even though the corresponding TID is not actually allocated. Proceed to ath12k_dp_rx_peer_tid_delete() starting from unallocated tid, which might leads to freeing unallocated TID and cause potential crash or out-of-bounds access. Hence, fix by correctly decrementing tid before cleanup to match only the successfully allocated TIDs. Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(), as decrementing the tid before cleanup in loop will take care of this. Compile tested only.

9 dayswifi: ath12k: bring DFS support back for WCN7850Baochen Qiang
Due to the restrict in MAC80211 that DFS (Dynamic Frequency Selection) can't be enabled on multiple channels, commit 176f3009ae59 ("wifi: ath12k: support 2 channels for single pdev device") removes DFS support in order to support 2 channels concurrently, making AP mode not working on DFS channels [1]. Revert portions of that commit to bring DFS back, and add a new combination to support 2-channels concurrency. This is valid because the MAC80211 restrict works on each individual combination, but does not care about them as a whole, as far as DFS is concerned. This change applies to WCN7850 only, other chips are not affected.

11 dayswifi: ath12k: Fix TX status reporting to mac80211 when offload is enabledNithyanantham Paramasivam
Currently, the ath12k driver supports only the native Wi-Fi frame format. In this mode, the ieee80211_tx_status() function works correctly to report transmission status to mac80211, as it retrieves station information using sta_info_get_by_addrs(). However, this method is not applicable for Ethernet-converted packets, since sta_info_get_by_addrs() cannot extract station information from such formats. Retrieve station information using ath12k_peer_find_by_id() to support all frame formats, including native Wi-Fi, raw, and Ethernet.

2025-07-15wifi: ath12k: Use HTT_TCL_METADATA_VER_V1 in FTM modeAaradhana Sahu
Currently host sends HTT_TCL_METADATA_VER_V2 to the firmware regardless of the operating mode (Mission or FTM). Firmware expects additional software information (like peer ID, vdev ID, and link ID) in Tx packets when HTT_TCL_METADATA_VER_V2 is set. However, in FTM (Factory Test Mode) mode, no vdev is created on the host side (this is expected). As a result, the firmware fails to find the expected vdev during packet processing and ends up dropping packets. To fix this, send HTT_TCL_METADATA_VER_V1 in FTM mode because FTM mode doesn't support HTT_TCL_METADATA_VER_V2.

2025-07-14wifi: ath12k: Add support to enqueue management frame at MLD levelSriram R
A multi-link client can use any link for transmissions. It can decide to put one link in power save mode for longer periods while listening on the other links as per MLD listen interval. Unicast management frames sent to that link station might get dropped if that link station is in power save mode or inactive. In such cases, firmware can take decision on which link to use. Allow the firmware to decide on which link management frame should be sent on, by filling the hardware link with maximum value of u32, so that the firmware will not have a specific link to transmit data on and so the management frames will be link agnostic. For QCN devices, all action frames are marked as link agnostic. For WCN devices, if the device is configured as an AP, then all frames other than probe response frames, authentication frames, association response frames, re-association response frames and ADDBA response frames are marked as link agnostic and if the device is configured as a station, then all frames other than probe request frames, authentication frames, de-authentication frames and ADDBA response frames are marked as link agnostic.

2025-07-10wifi: ath12k: update unsupported bandwidth flags in reg rulesHarshitha Prem
The maximum bandwidth an interface can operate in is defined by the configured country. However, currently, it is able to operate in bandwidths greater than the allowed bandwidth. For example, the Central African Republic (CF) supports a maximum bandwidth of 40 MHz in both the 2 GHz and 5 GHz bands, but an interface is still able to operate in bandwidths higher than 40 MHz. This issue arises because the regulatory rules in the regd are not updated with these restrictions received from firmware on the maximum bandwidth. Hence, update the regulatory rules with unsupported bandwidth flags based on the maximum bandwidth to ensure compliance with country-specific regulations.

2025-07-07wifi: ath12k: properly set bit for pdev mask for firmware PPDU_STATS requestSarika Sharma
Currently, the HTT_H2T_MSG_TYPE_PPDU_STATS_CFG request uses bits 8 to 15 as the bitmask for HTT_PPDU_STATS_CFG_PDEV_ID for firmware PPDU_STATS. However, bit 8 is reserved for SOC stats, and the actual PDEV ID should be encoded using bits 9 to 15. This leads to incorrect PDEV ID encoding in the request, causing it to either ignore the request or apply it to the wrong PDEV. Additionally, pdev_mask calculation is done as pdev_mask = 1 << (i + 1); (i.e. i= num_rxmda_per_pdev) but this is not valid for multiple pdevs(multi-MAC configurations) with 1 rxdma per pdev, as this will mask the same value for all pdevs. To correctly identify each and exact MAC in multi-MAC configurations, the calculation should include ar->pdev_idx: pdev_mask = 1 << i + ar->pdev_idx; Due to these issues, the firmware does not send PPDU_STATS for the intended PDEV, leading to inaccurate and incomplete statistics on the host. This might trigger certain WARN_ON() conditions in host that rely on these statistics. Hence, change the bitmask for HTT_PPDU_STATS_CFG_PDEV_ID as bit 9 to 15 to properly fill the pdev id in request message and change the pdev_mask calculation to consider ar->pdev_idx to mask pdev correctly.

Ensure that all radios remain down when the driver operates in Factory Test Mode (FTM). Reject any userspace attempts to bring up an interface in this mode. Currently, the driver allows userspace to bring up the interface even though it operates in FTM mode, which violates FTM constraints and leads to FTM command failures. Hence, block the radio start when the driver is in FTM mode.

Currently rx and tx MCS map for 160 MHz under HE capabilities are not updating properly, when 160 MHz is configured with NSS lesser than max NSS support. Fix this by utilizing nss_ratio_enabled and nss_ratio_info fields sent by firmware in service ready event. However, if firmware advertises EXT NSS BW support in VHT caps as 1(1x2) and when nss_ratio_info indicates 1:1, reset the EXT NSS BW Support in VHT caps to 0 which indicates 1x1. This is to avoid incorrectly choosing 1:2 NSS ratio when using the default VHT caps advertised by firmware.

2025-06-27wifi: ath12k: fix timeout while waiting for regulatory update during ↵Aditya Kumar Singh
interface creation During interface creation, following print is observed on the console - Timeout while waiting for regulatory update This occurs due to commit 906619a00967 ("wifi: ath12k: handle regulatory hints during mac registration"), which introduced a completion mechanism to synchronize the regulatory update process. The intent behind this change is to coordinate the timing between when the firmware sends regulatory data to the driver and when the driver processes that data. However, during interface addition, if the 6 GHz band is active, the driver invokes ath12k_regd_update() to apply the appropriate 6 GHz power mode regulatory settings. At this point, there is no interaction with the firmware, so the completion object is not reinitialized. As a result, wait_for_completion() eventually times out, leading to the observed error log message. Hence to fix this, move all complete() on regd_update_completed to complete_all(). The complete() function signals only once, causing any subsequent waits without reinitialization to timeout. In this scenario, since waiting is unnecessary, complete_all() can be used instead, ensuring that subsequent calls to wait without reinitialization will simply bail out and not actually wait. This approach is ideal because if the firmware is not involved, there is no need to wait for the completion event. However, if the firmware is involved, it is guaranteed that the completion will be reinitialized, and thus, it would wait.

2025-06-26wifi: ath12k: Clear auth flag only for actual association in security modeThiraviyam Mariyappan
When setting a new bitrate, WMI peer association command is sent from the host without the peer authentication bit set in peer_flags for security mode, which causes ping failure. The firmware handles peer_flags when the client is associating, as the peer authentication bit in peer_flags is set after the key exchange. When the WMI peer association command is sent from the host to update the new bitrate for an associated STA, the firmware expects the WMI peer authentication bit to be set in peer_flags. Fix this issue by ensuring that the WMI peer auth bit is set in peer_flags in WMI peer association command when updating the new bitrate.

2025-06-26wifi: ath12k: fix dest ring-buffer corruption when ring is fullJohan Hovold
Add the missing memory barriers to make sure that destination ring descriptors are read before updating the tail pointer (and passing ownership to the device) to avoid memory corruption on weakly ordered architectures like aarch64 when the ring is full.

Add the missing memory barrier to make sure that LMAC source ring descriptors are written before updating the head pointer to avoid passing stale data to the firmware on weakly ordered architectures like aarch64. Note that non-LMAC rings use MMIO write accessors which have the required write memory barrier.
