    cfg80211/mac80211: fix BSS leaks when abandoning assoc attempts · e6f462df
    Johannes Berg authored
    When mac80211 abandons an association attempt, it may free
    all the data structures, but inform cfg80211 and userspace
    about it only by sending the deauth frame it received, in
    which case cfg80211 has no link to the BSS struct that was
    used and will not cfg80211_unhold_bss() it.
    
    Fix this by providing a way to inform cfg80211 of this with
    the BSS entry passed, so that it can clean up properly, and
    use this ability in the appropriate places in mac80211.
    
    This isn't ideal: some code is more or less duplicated and
    tracing is missing. However, it's a fairly small change and
    it's thus easier to backport - cleanups can come later.
