2025-03-27wifi: ath12k: Replace band define G with GHZ where appropriateKarthikeyan Periyasamy
Currently, band define and enum are with the word 'G'. Replace it with more appropriate 'GHZ' for clarity and correctness. No functional changes. Only compile tested.

2025-03-27wifi: ath12k: Avoid fetch Error bitmap and decap format from Rx TLVP Praneesh
Currently, error bitmap and decap format information are fetched from the MSDU Rx TLV data. This logic is inherited from ath11k. However, for ath12k 802.11be hardware, the Rx TLV will not be present in the MSDU data. Instead, this information is reported separately under the MSDU END TLV tag. Therefore, remove the existing fetch code, handle the MSDU END TLV tag and fetch the above information to store it in the mon_mpdu data structure for use in the merge MSDU procedure.

2025-03-27wifi: ath12k: Add extra TLV tag parsing support in monitor Rx pathP Praneesh
Currently, the monitor Rx parser handler is inherited from the ath11k. However, the ath12k 802.11be hardware does not report the Rx TLV header in the MSDU data. Instead, the hardware reports those TLVs under the following TLV tags: 1. Buffer address 2. MPDU start 3. MPDU end 4. MSDU end Therefore, add support for parsing the above TLVs in the Rx monitor path and use this information for MSDU buffer and status updates.

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.

2025-02-28wifi: ath12k: Fix invalid data access in ath12k_dp_rx_h_undecap_nwifiManish Dharanenthiran
In certain cases, hardware might provide packets with a length greater than the maximum native Wi-Fi header length. This can lead to accessing and modifying fields in the header within the ath12k_dp_rx_h_undecap_nwifi function for DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and potentially resulting in invalid data access and memory corruption. Add a sanity check before processing the SKB to prevent invalid data access in the undecap native Wi-Fi function for the DP_RX_DECAP_TYPE_NATIVE_WIFI decap type.

2025-02-28wifi: ath12k: Report proper tx completion status to mac80211Vinith Kumar R
Currently Tx completion for few exception packets are received from firmware and the tx status updated to mac80211. The tx status values of HAL_WBM_REL_HTT_TX_COMP_STATUS_DROP and HAL_WBM_REL_HTT_TX_COMP_STATUS_TTL are considered as tx failure and reported as tx failure to mac80211. But these failure status is due to internal firmware tx drop and these packets were not tried to transmit in the air. In case of mesh this invalid tx status report might trigger mpath broken issue due to increase in mpath fail average. So do not report these tx status as tx failure instead free the skb by calling ieee80211_free_txskb(), and that will be accounted as dropped frame.

2025-02-26wifi: ath12k: Improve BSS discovery with hidden SSID in 6 GHz bandRamasamy Kaliappan
Currently, sometimes, the station is unable to identify the configured AP SSID in its scan results when the AP is not broadcasting its name publicly and has a hidden SSID. Currently, channel dwell time for an ath12k station is 30 ms. Sometimes, station can send broadcast probe request to AP close to the end of dwell time. In some of these cases, before AP sends a response to the received probe request, the dwell time on the station side would come to an end. So, the station will move to scan next channel and will not be able to acknowledge the unicast probe response. Resolve this issue by increasing station's channel dwell time to 70 ms, so that the it remains on the same channel for a longer period. This would increase the station's chance of receiving probe response from the AP. The station will then send a response acknowledgment back to the AP, thus leading to successful scan and BSS discovery. With an increased dwell time, scan would take longer than it takes now. But, this fix is an improvement for hidden SSID scan issue.

2025-02-24wifi: ath12k: Add NULL check to validate tpc_statsRoopni Devanathan
While processing TPC stats received from firmware, there are chances that the tpc_stats might not be filled and the data is not available. This can happen under two scenarios. First, when firmware sends a non-zero event count before event count 0. When this happens, tpc_stats will be checked for data before memory allocation and the tpc_stats will be unavailable. Second, when memory allocation failed when event count received is 0 and the firmware still sends a non-zero event. When this happens, memory will not be allocated for tpc_stats though event count is 0, so when non-zero event count is received, tpc_stats will be empty. There are checks to validate if tpc_stats variable is filled that are used in two subsequent places, but these are placed after tpc_stats is dereference without checking if it is NULL or has valid data. Fix this by removing the mentioned checks and adding a NULL check after assigning tpc_stats to check if it is valid.
