From 1a1cb744de160ee70086a77afff605bbc275d291 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 19 Mar 2014 09:55:55 +0100 Subject: mac80211: fix suspend vs. authentication race Since Stanislaw's patch removing the quiescing code, mac80211 had a race regarding suspend vs. authentication: as cfg80211 doesn't track authentication attempts, it can't abort them. Therefore the attempts may be kept running while suspending, which can lead to all kinds of issues, in at least some cases causing an error in iwlmvm firmware. Fix this by aborting the authentication attempt when suspending.
