Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix atomic calls in ath12k_mac_op_set_bitrate_mask() When I try to manually set bitrates: iw wlan0 set bitrates legacy-2.4 1 I get sleeping from invalid context error, see below. Fix that by switching to use recently introduced ieee80211_iterate_stations_mtx(). Do note that WCN6855 firmware is still crashing, I'm not sure if that firmware even supports bitrate WMI commands and should we consider disabling ath12k_mac_op_set_bitrate_mask() for WCN6855? But that's for another patch.
