From c1fbb258846dfc425507a093922d2d001e54c3ea Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Wed, 30 Apr 2014 15:58:13 +0300 Subject: 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.
