[B.A.T.M.A.N.] ibss.c backtrace when batman-adv adds wireless interface
by Josh Boyer 03 Feb '16

03 Feb '16

Hi All, We've had a user report the backtrace below when loading batman-adv on his machine. It looks like the cfg80211 layer is complaining about a null bss returned, but I cannot tell if the rtlwifi driver or batman-adv is in error here.
