The previous implementation included an unnecessary else condition paired with a continue statement. Since a check is already performed to determine if the band is either 2G or 5G, the else condition will never be triggered. We can remove this check.

2024-10-25wifi: rtw89: add thermal protectionPing-Ke Shih13-5/+138
To prevent chip overheating, reduce TX duty as the mechanism of thermal protection. When temperature is raising over a threshold, send a firmware command to reduce TX duty. If temperature is still raising, higher level is adopted to have lower active duration. The equation and unit of thermal values are different from chip to chip, so define constant thresholds of thermal value to corresponding absolute temperature of 110 and 120 degree Celsius. Latter patch will decide which thermal threshold is adopted, and current is still not enable thermal protection. For debugging, add a flag to disable_dm that thermal protection can be disabled to clarify low throughput in field.

2024-10-23wifi: ath12k: fix A-MSDU indication in monitor modeKang Yang1-2/+13
In monitor mode, host will reap MSDUs and then the MSDUs with same PPDU ID will be aggregated into an A-MSDU in ath12k_dp_mon_rx_merg_msdus(). However, ath12k_dp_mon_rx_merg_msdus() doesn't calculate the total length of the A-MSDU. This causes Wireshark to display the A-MSDU incorrectly. Therefore, need to add calculation of the A-MSDU length.

2024-10-23wifi: ath12k: use tail MSDU to get MSDU informationKang Yang1-18/+23
When receiving a packet in monitor mode, hardware will fill status information msdu_end for MSDUs. Then host can use these status information to get specific information about this packet, such as l3 offset, bandwidth, mcs, packet type. If this packet is composed of multiple MSDUs, then hardware will only fill status information for the last(tail) MSDU. At this time, MSDU information is uncertain for others MSDUs. But current code use the first MSDU in monitor mode, so will get the wrong information. Fix it by getting msdu information from last(tail) msdu.

2024-10-23wifi: mac80211: re-order assigning channel in activate linksAditya Kumar Singh2-24/+19
The current flow in _ieee80211_set_active_links() does not align with the operational requirements of drivers that groups multiple hardware under a single wiphy. These drivers (e.g ath12k) rely on channel assignment to determine the appropriate hardware for each link. Without this, the drivers cannot correctly establish the link interface. Currently in _ieee80211_set_active_links(), after calling drv_change_vif_links() on the driver, the state of all connected stations is updated via drv_change_sta_links(). This is followed by handling keys in the links, and finally, assigning the channel to the links. Consequently, drv_change_sta_links() prompts drivers to create the station entry at their level and within their firmware. However, since channels have not yet been assigned to links at this stage, drivers have not created the necessary link interface for establishing link stations, leading to failures in activating the links. Therefore, re-order the logic so that after drv_change_vif_links() and removing the old links, channels are assigned to newly added links. Following this, the flow proceeds to station handling.

Instead of hrtimer_is_queued(), use hrtimer_active() since it might be running concurrently, and then it's not queued at that point in time, as suggested by Thomas Gleixner in https://lore.kernel.org/87plqn5psu.ffs@tglx, I just never got to this for ages. I think the concurrency is otherwise fine since we'll get to cancel if we're actually removing things, and otherwise we just send a beacon at slightly the wrong time or so.

In practice, userspace hasn't been able to set this for many years, and mac80211 has already rejected it (which is now no longer needed), so reject SMPS mode (other than "OFF" to be a bit more compatible) in AP mode. Also remove the parameter from the AP settings struct.

If there is an error during some initialization related to firmware, the buffers dp->tx_ring[i].tx_status are released. However this is released again when the device is unbinded (ath12k_pci), and we get: WARNING: CPU: 0 PID: 2098 at mm/slub.c:4689 free_large_kmalloc+0x4d/0x80 Call Trace: free_large_kmalloc ath12k_dp_free ath12k_core_deinit ath12k_pci_remove ... The issue is always reproducible from a VM because the MSI addressing initialization is failing. In order to fix the issue, just set the buffers to NULL after releasing in order to avoid the double free. cc: stable@vger.kernel.org Fixes: d889913205cf ("wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices") Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> Link: https://patch.msgid.link/20241017181004.199589-3-jtornosm@redhat.com Signed-off-by: Jeff Johnson <quic_jjohnson@quicinc.com>

2024-10-22wifi: ath12k: remove msdu_end structure for WCN7850Lingbo Kong2-80/+20
Currently, when ath12k retrieves values from the structure rx_msdu_end_wcn7850, the information obtained is incorrect. This is because the definition of the rx_msdu_end_wcn7850 structure in ath12k is incorrect. In fact, the rx_msdu_end structure used by WCN7850 is the same as the rx_msdu_end structure of QCN9274. Commit ed823fd113b7 ("wifi: ath12k: add msdu_end structure for WCN7850") introduced this structure. The original issue trying to be fixed with that commit is that the TID information retrieved from the rx_msdu_end structure was incorrect, and it was thought that the structure wasn't correct, so a supposedly correct structure was introduced. However it was subsequently discovered that the TID information is only guaranteed to be valid in the rx_msdu_start structure, so that commit added the logic to retrieve the TID from the rx_msdu_start, but unfortunately kept the rx_msdu_end_wcn7850 structure. To address this issue, revert the code related to the rx_msdu_end_wcn7850 structure, retaining the TID retrieval logic. This patch does not affect QCN9274.

2024-10-20wifi: rtw89: wow: cast nd_config->delay to u64 in tsf arithmeticPing-Ke Shih1-1/+1
The type of tsf arithmetic is u64 += u16 * int; When (u16 * int) is larger than 0x7FFFFFFF, the value casting to u64 with sign-extension will become all 1 in upper 32 bits part. To meet the case, u16 value should be larger than 20491 (0x7FFFFFFF / 104800). Fortunately the meaning of 20491 is delay time of WoWLAN net detection in unit of second, so 20491 seconds (5.7 hours) might not a real case we can meet.
