charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit I'm trying to investigate a WARN_ON() in subject, seen at least once with 5.10.200 under syzkaller. Surely this may be a weird artifact of using the syzkaller itself, but is there a scenario to trigger this WARN_ON() in a "real" environment? And, looking through the code, is it a good idea to call 'cfg80211_get_bss()' without checking whether the corresponding BSSID is non-zero? Thanks, Dmitry
