WARN_ON(!cbss) at net/mac80211/ibss.c:488

[Dmitry Antipov <dmantipov@xxxxxxxxx>]

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
