* wifi: ath12k: fix WMI TLV header misalignmentMiaoqing Pan2025-09-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | When buf_len is not 4-byte aligned in ath12k_wmi_mgmt_send(), the firmware asserts and triggers a recovery. The following error messages are observed: ath12k_pci 0004:01:00.0: failed to submit WMI_MGMT_TX_SEND_CMDID cmd ath12k_pci 0004:01:00.0: failed to send mgmt frame: -108 ath12k_pci 0004:01:00.0: failed to tx mgmt frame, vdev_id 0 :-108 ath12k_pci 0004:01:00.0: waiting recovery start... This issue was observed when running 'iw wlanx set power_save off/on' in MLO station mode, which triggers the sending of an SMPS action frame with a length of 27 bytes to the AP. To resolve the misalignment, use buf_len_aligned instead of buf_len when constructing the WMI TLV header.

* wifi: ath12k: Fix missing station power save configurationMiaoqing Pan2025-09-081-55/+67
| | | | | | | | | | | | | | | | | | | | Commit afbab6e4e88d ("wifi: ath12k: modify ath12k_mac_op_bss_info_changed() for MLO") replaced the bss_info_changed() callback with vif_cfg_changed() and link_info_changed() to support Multi-Link Operation (MLO). As a result, the station power save configuration is no longer correctly applied in ath12k_mac_bss_info_changed(). Move the handling of 'BSS_CHANGED_PS' into ath12k_mac_op_vif_cfg_changed() to align with the updated callback structure introduced for MLO, ensuring proper power-save behavior for station interfaces.

* wifi: ath12k: Set EMLSR support flag in MLO flags for EML-capable stationsRamya Gnanasekar2025-09-021-0/+1
| | | | | | | | | | | | | | | | | | | | | Currently, when updating EMLSR capabilities of a multi-link (ML) station, only the EMLSR parameters (e.g., padding delay, transition delay, and timeout) are sent to firmware. However, firmware also requires the EMLSR support flag to be set in the MLO flags of the peer assoc WMI command to properly handle EML operating mode notification frames. Set the ATH12K_WMI_FLAG_MLO_EMLSR_SUPPORT flag in the peer assoc WMI command when the ML station is EMLSR-capable, so that the firmware can respond to EHT EML action frames from associated stations.

| * wifi: ath12k: Correct tid cleanup when tid setup failsSarika Sharma2025-07-211-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the mac80211 layer handles construction and parsing of 802.11 headers during packet transmission and reception.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

As a result, mac80211 performs unnecessary monitor mode checks on each packet, even though these packets are not intended for monitor mode processing. In regular rx path, this flag is explicitly set to avoid such overhead. Align the WBM error path behavior by setting RX_FLAG_SKIP_MONITOR to prevent redundant per-packet checks in mac80211.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

| * wifi: ath12k: Clear auth flag only for actual association in security modeThiraviyam Mariyappan2025-06-262-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
