2025-11-06wifi: rtw89: refine rtw89_core_tx_wait_complete()Fedor Pchelkin
Pass TX status value directly into rtw89_core_tx_wait_complete(). This will make it a bit in sync with further patches and will give flexibility in future work. Also use scope based RCU locking which simplifies the code of the function. Found by Linux Verification Center (linuxtesting.org).

2025-11-05wifi: mac80211_hwsim: Limit destroy_on_close radio removal to netgroupMartin Willi
hwsim radios marked destroy_on_close are removed when the Netlink socket that created them is closed. As the portid is not unique across network namespaces, closing a socket in one namespace may remove radios in another if it has the destroy_on_close flag set. Instead of matching the network namespace, match the netgroup of the radio to limit radio removal to those that have been created by the closing Netlink socket. The netgroup of a radio identifies the network namespace it was created in, and matching on it removes a destroy_on_close radio even if it has been moved to another namespace.

2025-11-05wifi: ath12k: Move DP specific link stats to DP link peerHarsh Kumar Bijlani
As part of peer modularization in the Driver Framework, the station view is as follows: Common Path Data Path ------------------------------------------------------------------- ath12k_sta ath12k_dp_peer | | |-> ath12k_link_sta <----> |-> ath12k_dp_link_peer | | |-> ath12k_link_sta <----> |-> ath12k_dp_link_peer | | |-> ath12k_link_sta <----> |-> ath12k_dp_link_peer Currently ath12k_link_sta has data path stats updated in tx_htt and rx monitor path. Move those stats from ath12_link_sta to ath12k_dp_link_peer to align with peer modularization model as shown above. This allows datapath to use only ath12k_dp_link_peer without having to reach out to other objects for updating stats, thereby improving the cache locality. Add following API to fetch rate info from DP link peer: ath12k_dp_link_peer_get_sta_rate_info_stats() This wrapper API populates link stats in 'struct ath12k_dp_link_peer_rate_info', which can be extended to support out-of-band retrieval of various rate stats.

2025-11-04wifi: rtw89: 8852c: Fix rtw8852c_pwr_{on,off}_func() for USBBitterblue Smith
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 RTL8832CU to be able to power on again after it's powered off. While the RTL8832CU 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.

2025-10-30wifi: ath12k: unassign arvif on scan vdev create failureRameshkumar Sundaram
During scan and remain-on-channel requests, a scan link vif (arvif) is assigned and a temporary vdev is created. If vdev creation fails, the assigned arvif is left attached until the virtual interface is removed, leaving a stale link in ahvif. Fix this by freeing the stale arvif and resetting the corresponding link in ahvif by calling ath12k_mac_unassign_link_vif() when vdev creation fails. While at it, propagate the actual error code from ath12k_mac_vdev_create() instead of returning -EINVAL in ath12k_mac_initiate_hw_scan().

Currently, vdev limit check is performed only in ath12k_mac_assign_vif_to_vdev(). If the host has already created maximum number of vdevs for the radio (ar) and a scan request arrives for the same radio, ath12k_mac_initiate_hw_scan() attempts to create a vdev without checking the limit, causing firmware asserts. Centralize the vdev limit guard by moving the check into ath12k_mac_vdev_create() so that all callers obey the limit. While doing this, update the condition from `num_created_vdevs > (TARGET_NUM_VDEVS(ab) - 1)` to `num_created_vdevs >= TARGET_NUM_VDEVS(ab)` for clarity and to eliminate unnecessary arithmetic.

During firmware recovery or suspend/resume, m3 memory could be reused if the size of the new m3 binary is equal to or less than that of the existing memory. There will be issues for the latter case, since m3_mem->size will be updated with a smaller value and this value is eventually used in the free path, where the original total size should be used instead.
