Subject: [added to the 4.1 stable tree] qla2xxx: added sess generations to detect RSCN update races
Date: Wed, 2 Mar 2016 15:13:19 -0500 [thread overview]
Message-ID: <1456949673-25036-12-git-send-email-sasha.levin@oracle.com> (raw)
In-Reply-To: <1456949673-25036-1-git-send-email-sasha.levin@oracle.com>
From: Alexei Potashnik <alexei@purestorage.com>
This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit df673274fa4896f25f0bf348d2a3535d74b4cbec ]
RSCN processing in qla2xxx driver can run in parallel with ELS/IO
processing. As such the decision to remove disappeared fc port's
session could be stale, because a new login sequence has occurred
since and created a brand new session.
Previous mechanism of dealing with this by delaying deletion request
was prone to erroneous deletions if the event that was supposed to
cancel the deletion never arrived or has been delayed in processing.
New mechanism relies on a time-like generation counter to serialize
RSCN updates relative to ELS/IO updates.
