    mac80211: fix direct probe loop on ieee80211_work_purge · 0e0a2283
    Juuso Oikarinen authored
    If authentication has already been performed when the WLAN interface is
    stopped, (sometimes) the ieee80211_work_purge would corrupt some
    ieee80211_work-structures. The outcome is this (cleaned up):
    
    [ 2252.398681] WARNING: at net/mac80211/work.c:995 ieee80211_work_purge
    [ 2252.466430] Backtrace:
    [ 2252.529266] (ieee80211_work_purge+0x0/0xcc [mac80211])
    [ 2252.546875] (ieee80211_stop+0x0/0x4c0 [mac80211])
    
    Additionally, one would get this, going on regarless of the WLAN interface
    state, going on forever:
