wifi: iwlwifi: pcie: fix byte count table for some devices

2025-09-15T08:20:47Z

In my previous fix for this condition, I erroneously listed 9000 instead of 7000 family, when 7000/8000 were already using iwlmvm. Thus the condition ended up wrong, causing the issue I had fixed for older devices to suddenly appear on 7000/8000 family devices. Correct the condition accordingly.

wifi: iwlwifi: fix 130/1030 configs

2025-09-09T10:54:26Z

The 130/1030 devices are really derivatives of 6030, with some small differences not pertaining to the MAC, so they must use the 6030 MAC config.

wifi: ath12k: fix WMI TLV header misalignment

2025-09-08T16:45:18Z

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 configuration

2025-09-08T16:45:18Z

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: wilc1000: avoid buffer overflow in WID string configuration

2025-09-03T07:39:32Z

Fix the following copy overflow warning identified by Smatch checker. drivers/net/wireless/microchip/wilc1000/wlan_cfg.c:184 wilc_wlan_parse_response_frame() error: '__memcpy()' 'cfg->s[i]->str' copy overflow (512 vs 65537) This patch introduces size check before accessing the memory buffer. The checks are base on the WID type of received data from the firmware. For WID string configuration, the size limit is determined by individual element size in 'struct wilc_cfg_str_vals' that is maintained in 'len' field of 'struct wilc_cfg_str'.
