Subject: [ 16/27] target: Fix incorrect fallthrough of ALUA Standby/Offline/Transition CDBs
Date: Sun, 14 Apr 2013 19:43:15 -0700	[thread overview]
Message-ID: <20130415024232.569495413@linuxfoundation.org> (raw)
In-Reply-To: <20130415024231.351969241@linuxfoundation.org>

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Bellinger <nab@linux-iscsi.org>

commit 30f359a6f9da65a66de8cadf959f0f4a0d498bba upstream.

This patch fixes a bug where a handful of informational / control CDBs
that should be allowed during ALUA access state Standby/Offline/Transition
where incorrectly returning CHECK_CONDITION + ASCQ_04H_ALUA_TG_PT_*.

This includes INQUIRY + REPORT_LUNS, which would end up preventing LUN
registration when LUN scanning occured during these ALUA access states.
