Patch 2 fixes that. Patch 1 is new: with the firmware down, a key whose removal failed stayed in peer->keys[] although mac80211 had freed it. I used Claude (Anthropic) to help write these patches. Tested on an IPQ8074 AP (hw2.0 AHB, WLAN.HK.2.12-01460): the firmware was crashed through debugfs and the station deleted at once. In 3 of 3 runs with this series station del returned 0 with no mac80211 warning and no key removal error, and the station re-associated. With the v1 patch alone, one run logged "failed to remove peer key 0: -108" and "failed to clear all peer keys for vdev 0: -108". Changes in v2: - New patch 1. - Patch 2: continue the host cleanup after a failed early vdev stop and a failed RTS/CTS update instead of returning from them (Sashiko review of v1). v1: https://lore.kernel.org/all/20261101174422.1275413-1-julius@bairaktaris.de/ Julius Bairaktaris (2): wifi: ath11k: forget a key the firmware failed to remove wifi: ath11k: do not fail down transitions of the station state drivers/net/wireless/ath/ath11k/mac.c | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) base-commit: 1be6c8d3027d4a421dc46b93a89a196c61945614 -- 2.53.0
