In cfg80211_send_rx_auth function there was a warning if bssid of the received authentication message was not found from the authtry_bsses table. During the beginning of the authentication there is a small time window, when handling of the received deauthentication message can cause information for the access point to be removed from the authtry_bsses table before authentication response is received. This triggers the warning. This has been seen happening with several access points occasionally. At least one of those (Asus) has been seen to send spurious deauthentication messages after deauthentication. Possibly this warning could be triggered also by forged deauthentication messages sent at a correct time.
