11 dayswifi: iwlwifi: mld: Move regulatory domain initializationIlan Peer
The regulatory domain information was initialized every time the FW was loaded and the device was restarted. This was unnecessary and useless as at this stage the wiphy channels information was not setup yet so while the regulatory domain was set to the wiphy, the channel information was not updated. In case that a specific MCC was configured during FW initialization then following updates with this MCC are ignored, and thus the wiphy channels information is left with information not matching the regulatory domain. This commit moves the regulatory domain initialization to after the operational firmware is started, i.e., after the wiphy channels were configured and the regulatory information is needed.

11 dayswifi: iwlwifi: mld: avoid panic on init failureMiri Korenblit
In case of an error during init, in_hw_restart will be set, but it will never get cleared. Instead, we will retry to init again, and then we will act like we are in a restart when we are actually not. This causes (among others) to a NULL pointer dereference when canceling rx_omi::finished_work, that was not even initialized, because we thought that we are in hw_restart. Set in_hw_restart to true only if the fw is running, then we know that FW was loaded successfully and we are not going to the retry loop.

2025-05-27wifi: iwlwifi: mld: Work around Clang loop unrolling bugKees Cook
The nested loop in iwl_mld_send_proto_offload() confuses Clang into thinking there could be a final loop iteration past the end of the "nsc" array (which is only 4 entries). The FORTIFY checking in memcmp() (via ipv6_addr_cmp()) notices this (due to the available bytes in the out-of-bounds position of &nsc[4] being 0), and errors out, failing the build. For some reason (likely due to architectural loop unrolling configurations), this is only exposed on ARM builds currently. Due to Clang's lack of inline tracking[1], the warning is not very helpful: include/linux/fortify-string.h:719:4: error: call to '__read_overflow' declared with 'error' attribute: detected read beyond size of object (1st parameter) 719 | __read_overflow(); | ^ 1 error generated. But this was tracked down to iwl_mld_send_proto_offload()'s ipv6_addr_cmp() call. An upstream Clang bug has been filed[2] to track this. For now fix the build by explicitly bounding the inner loop by "n_nsc", which is what "c" is already limited to.

2025-05-22wifi: mt76: mt7996: fix RX buffer size of MCU eventShayne Chen
Some management frames are first processed by the firmware and then passed to the driver through the MCU event rings. In CONNAC3, event rings do not support scatter-gather and have a size limitation of 2048 bytes. If a packet sized between 1728 and 2048 bytes arrives from an event ring, the ring will hang because the driver attempts to use scatter-gather to process it. To fix this, include the size of struct skb_shared_info in the MCU RX buffer size to prevent scatter-gather from being used for event skb in mt76_dma_rx_fill_buf().

2025-05-21wifi: ath12k: fix regdomain update failure when connection establishesBaochen Qiang
Commit 7ed3e88664e3 ("wifi: ath12k: update regulatory rules when connection established") introduced a call to ath12k_reg_handle_chan_list() upon connection to update the regulatory domain in cfg80211 based on the power type received from the AP. However, this update fails because ah->regd_updated was already set to true during the earlier regulatory update triggered when the interface was added. To resolve this, reset ah->regd_updated before calling ath12k_reg_handle_chan_list() to ensure the update proceeds correctly.

2025-05-21wifi: ath12k: fix regdomain update failure when adding interfaceBaochen Qiang
Commit 4c546023d71a ("wifi: ath12k: update regulatory rules when interface added"), introduced a call to ath12k_reg_handle_chan_list() during interface addition to update the regulatory domain based on the interface type. While this works initially, subsequent updates (e.g., after an interface delete/re-add cycle) fail because ah->regd_updated is never reset. To address this, reset ah->regd_updated before calling ath12k_reg_handle_chan_list() to allow the update to proceed. However, this change exposes another issue: a timeout occurs when waiting for the 11D scan to complete, as seen in the log: ath12k_pci 0000:05:00.0: failed to receive 11d scan complete: timed out This happens because during interface down, ar->state_11d is set to ATH12K_11D_PREPARING, and during interface up, the host waits for ar->completed_11d_scan even though the scan hasn't started yet. Fix this by updating the wait condition to check for ATH12K_11D_RUNNING, which is the only state where a scan complete event is expected. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1 Fixes: 4c546023d71a ("wifi: ath12k: update regulatory rules when interface added") Signed-off-by: Baochen Qiang <quic_bqiang@quicinc.com> Signed-off-by: Aditya Kumar Singh <aditya.kumar.singh@oss.qualcomm.com> Link: https://patch.msgid.link/20250521-ath12k-fix-ah-regd_updated-v1-2-9737de5bf98e@oss.qualcomm.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>
2025-05-21wifi: ath12k: fix regdomain update failure after 11D scan completesBaochen Qiang
In the current implementation of ath12k_regd_update(), the ah->regd_updated flag is used to ensure that the regulatory domain is updated only once per radio. During MAC registration, this function is called to push the default regulatory domain to cfg80211. At that point, the hardware state is not on and hence ah->regd_updated remains false. However, after commit 4c546023d71a ("wifi: ath12k: update regulatory rules when interface added"), ath12k_reg_handle_chan_list() is invoked when an interface is added, which in turn calls ath12k_regd_update(). By this time, hardware state is on and consecutively ah->regd_updated becomes true. Later, when the 11D scan completes and a new regulatory domain is received from the firmware, the host attempts to update cfg80211 again via ath12k_regd_update(). But since ah->regd_updated is already true, the update is skipped. >From the user's perspective, this results in a failure to connect to 6 GHz APs, as the default regulatory domain (the only one pushed to cfg80211) does not include 6 GHz support. To resolve this, reset the ah->regd_updated flag when handling the 11D regulatory domain update.
