2025-07-08wifi: ath12k: fill link station statistics for MLOSarika Sharma1-0/+78
Introduce ath12k_mac_op_link_sta_statistics(), to report link level station statistics for MLO. The link_station_info structure is filled from arsta and arsta is fetch from corresponding ahsta->link[link_id]. Therefore, this will be helpful to check the link related statistics.

2025-07-07wifi: mt76: mt7925: prevent NULL pointer dereference in ↵Deren Wu1-0/+6
mt7925_sta_set_decap_offload() Add a NULL check for msta->vif before accessing its members to prevent a kernel panic in AP mode deployment. This also fix the issue reported in [1]. The crash occurs when this function is triggered before the station is fully initialized. The call trace shows a page fault at mt7925_sta_set_decap_offload() due to accessing resources when msta->vif is NULL. Fix this by adding an early return if msta->vif is NULL and also check wcid.sta is ready. This ensures we only proceed with decap offload configuration when the station's state is properly initialized.

2025-07-07wifi: mwifiex: discard erroneous disassoc frames on STA interfaceVitor Soares1-1/+3
When operating in concurrent STA/AP mode with host MLME enabled, the firmware incorrectly sends disassociation frames to the STA interface when clients disconnect from the AP interface. This causes kernel warnings as the STA interface processes disconnect events that don't apply to it: [ 1303.240540] WARNING: CPU: 0 PID: 513 at net/wireless/mlme.c:141 cfg80211_process_disassoc+0x78/0xec [cfg80211] [ 1303.250861] Modules linked in: 8021q garp stp mrp llc rfcomm bnep btnxpuart nls_iso8859_1 nls_cp437 onboard_us [ 1303.327651] CPU: 0 UID: 0 PID: 513 Comm: kworker/u9:2 Not tainted 6.16.0-rc1+ #3 PREEMPT [ 1303.335937] Hardware name: Toradex Verdin AM62 WB on Verdin Development Board (DT) [ 1303.343588] Workqueue: MWIFIEX_RX_WORK_QUEUE mwifiex_rx_work_queue [mwifiex] [ 1303.350856] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 1303.357904] pc : cfg80211_process_disassoc+0x78/0xec [cfg80211] [ 1303.364065] lr : cfg80211_process_disassoc+0x70/0xec [cfg80211] [ 1303.370221] sp : ffff800083053be0 [ 1303.373590] x29: ffff800083053be0 x28: 0000000000000000 x27: 0000000000000000 [ 1303.380855] x26: 0000000000000000 x25: 00000000ffffffff x24: ffff000002c5b8ae [ 1303.388120] x23: ffff000002c5b884 x22: 0000000000000001 x21: 0000000000000008 [ 1303.395382] x20: ffff000002c5b8ae x19: ffff0000064dd408 x18: 0000000000000006 [ 1303.402646] x17: 3a36333a61623a30 x16: 32206d6f72662063 x15: ffff800080bfe048 [ 1303.409910] x14: ffff000003625300 x13: 0000000000000001 x12: 0000000000000000 [ 1303.417173] x11: 0000000000000002 x10: ffff000003958600 x9 : ffff000003625300 [ 1303.424434] x8 : ffff00003fd9ef40 x7 : ffff0000039fc280 x6 : 0000000000000002 [ 1303.431695] x5 : ffff0000038976d4 x4 : 0000000000000000 x3 : 0000000000003186 [ 1303.438956] x2 : 000000004836ba20 x1 : 0000000000006986 x0 : 00000000d00479de [ 1303.446221] Call trace: [ 1303.448722] cfg80211_process_disassoc+0x78/0xec [cfg80211] (P) [ 1303.454894] cfg80211_rx_mlme_mgmt+0x64/0xf8 [cfg80211] [ 1303.460362] mwifiex_process_mgmt_packet+0x1ec/0x460 [mwifiex] [ 1303.466380] mwifiex_process_sta_rx_packet+0x1bc/0x2a0 [mwifiex] [ 1303.472573] mwifiex_handle_rx_packet+0xb4/0x13c [mwifiex] [ 1303.478243] mwifiex_rx_work_queue+0x158/0x198 [mwifiex] [ 1303.483734] process_one_work+0x14c/0x28c [ 1303.487845] worker_thread+0x2cc/0x3d4 [ 1303.491680] kthread+0x12c/0x208 [ 1303.495014] ret_from_fork+0x10/0x20 Add validation in the STA receive path to verify that disassoc/deauth frames originate from the connected AP.

This filtering logic is similar with that used in the ieee80211_rx_mgmt_disassoc() function in mac80211, which drops disassoc frames that don't match the current BSSID (!ether_addr_equal(mgmt->bssid, sdata->vif.cfg.ap_addr)), ensuring only relevant frames are processed.

There are a few differences in the power on/off functions between PCIE and USB. The changes in the power off function in particular are needed for the RTL8832BU to be able to power on again after it's powered off. While the RTL8832BU appears to work without the changes in the power on function, it's probably best to implement them, in case they are needed in some situations.

CONFIG_RFS_ACCEL I received a kernel-test-bot report[1] that shows the [-Wunused-but-set-variable] warning. Since the previous commit I made, as the 'Fixes' tag shows, gives users an option to turn on and off the CONFIG_RFS_ACCEL, the issue then can be discovered and reproduced with GCC specifically. Like Simon and Jakub suggested, use fewer #ifdefs which leads to fewer bugs.

2025-07-04wifi: rtw89: enter power save mode aggressivelyChin-Yen Lee6-29/+123
Currently the driver allows the WiFi chip enter power save mode by checking the transmitting and receiving traffic is very low per two seconds. But it's hard for some applications to enter power save mode, like video streaming, which sends burst traffic regularly for other side to buffer and only send little traffic at most time. So adjust the criteria to enter power save while lower than 10Mbps and check it per 100ms. Thus WiFi chip could reduce power consumption under these applications.
