Subject: [PATCH 0/3] mac80211: fix csa counters
Date: Thu, 22 May 2014 15:28:11 +0200 [thread overview]
Message-ID: <1400765294-14732-1-git-send-email-michal.kazior@tieto.com> (raw)
Hi,
I was seeing strange WARN_ON splat loops and
crashes while I was testing my multi-vif CSA.
CSA counters weren't properly reset and on some
failpaths this caused a mess. There were also
possible SMP inconsitencies/races.
Michal Kazior (3):
mac80211: move csa counters from sdata to beacon/presp
mac80211: use csa counter offsets instead of csa_active
mac80211: make csa_currnet_counter atomic
