Subject: [PATCH 4.4 24/36] mac80211: flush delayed work when entering suspend
Date: Mon, 13 Mar 2017 16:39:24 +0800 [thread overview]
Message-ID: <20170313083353.966059125@linuxfoundation.org> (raw)
In-Reply-To: <20170313083352.550085638@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matt Chen <matt.chen@intel.com>
commit a9e9200d8661c1a0be8c39f93deb383dc940de35 upstream.
The issue was found when entering suspend and resume.
It triggers a warning in:
mac80211/key.c: ieee80211_enable_keys()
...
WARN_ON_ONCE(sdata->crypto_tx_tailroom_needed_cnt ||
sdata->crypto_tx_tailroom_pending_dec);
...
It points out sdata->crypto_tx_tailroom_pending_dec isn't cleaned up successfully
in a delayed_work during suspend. Add a flush_delayed_work to fix it.
