From d662c14a51910ba0ad66afd248b601ba30b9f7f1 Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Wed, 21 May 2025 22:29:29 +0530 Subject: [PATCH] wifi: ath12k: fix regdomain update failure after 11D scan completes 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.
