Subject: [PATCH] cfg80211: free sme on connection failures
cfg80211 is notified about connection failures by
__cfg80211_connect_result() call. However, this
function currently does not free cfg80211 sme.
This results in hanging connection attempts in some cases
e.g. when mac80211 authentication attempt is denied,
we have this function call:
ieee80211_rx_mgmt_auth() -> cfg80211_rx_mlme_mgmt() ->
cfg80211_process_auth() -> cfg80211_sme_rx_auth() ->
__cfg80211_connect_result()
but cfg80211_sme_free() is never get called.
Fixes: ceca7b712 ("cfg80211: separate internal SME implementation")
