This is a note to let you know that I've just added the patch titled ath11k: fix AP mode for QCA6390 to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: ath11k-fix-ap-mode-for-qca6390.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b1670b113b0c23315d3fc95af7f119378084459d Author: Kalle Valo <kvalo@xxxxxxxxxxxxxx> Date: Mon Feb 22 17:14:09 2021 +0200 ath11k: fix AP mode for QCA6390 [ Upstream commit 77d7e87128d4dfb400df4208b2812160e999c165 ] Commit c134d1f8c436 ("ath11k: Handle errors if peer creation fails") completely broke AP mode on QCA6390: kernel: [ 151.230734] ath11k_pci 0000:06:00.0: failed to create peer after vdev start delay: -22 wpa_supplicant[2307]: Failed to set beacon parameters wpa_supplicant[2307]: Interface initialization failed wpa_supplicant[2307]: wlan0: interface state UNINITIALIZED->DISABLED wpa_supplicant[2307]: wlan0: AP-DISABLED wpa_supplicant[2307]: wlan0: Unable to setup interface. wpa_supplicant[2307]: Failed to initialize AP interface This was because commit c134d1f8c436 ("ath11k: Handle errors if peer creation fails") added error handling for ath11k_peer_create(), which had been failing all along but was unnoticed due to the missing error handling. The actual bug was introduced already in commit aa44b2f3ecd4 ("ath11k: start vdev if a bss peer is already created"). ath11k_peer_create() was failing because for AP mode the peer is created already earlier op_add_interface() and we should skip creation here, but the check for modes was wrong. Fixing that makes AP mode work again. This shouldn't affect IPQ8074 nor QCN9074 as they have hw_params.vdev_start_delay disabled.
