Subject: [scsi] be2iscsi: upstream driver refresh for rhel5.5
Message-id: <1264540087-2454-1-git-send-email-mchristi@redhat.com>

O-Subject: [PATCH PATCH RHEL 5.5]: Sync be2iscsi with upstream
Bugzilla: 554545
RH-Acked-by: Tomas Henzl <thenzl@redhat.com>
From: Mike Christie <mchristi@redhat.com>
This is for BZ 554545.
This patch syncs the driver with what is upstream/going-upstream.
It is mostly bug fixes found while testing the driver, but also
some noise for copyright updates. I am sending everything so
the driver is in sync with what is upstream.
Here is a list of patches in the scsi maintainer's tree.
Some of the code in this patch is in the scsi maitainer's tree:
http://git.kernel.org/?p=linux/kernel/git/jejb/scsi-misc-2.6.git;a=commit;h=756d

fb3aa4cc4e42241e194ef64931321fa72196
And some has been sent to the linux scsi list:

For be2iscsi, I have compile tested the patch and done a insmod, and
have tried to do IO, but I am still having trouble with the card. We are relying
on Emulex and Server Engines for testing.
For the other iscsi drivers that are affected (iser, iscsi_tcp,
cxgb3i and bnx2i) due to the addition of a new argument to
iscsi2_session_setup(), I ran the upstream regression test
script which creates and destroys sessions while setting
iscsi params to almost all valid values. I also did some
connection recvery tests where I rebooted the target, restarted
nics, or pulled cables and made sure we could reconnect.
The be2iscsi driver is new to 5.5, so this patch should not cause
regressions with that driver, and Emulex and ServerEngines are
doing all the QE so this patch will cause any issues with
invalidating partner testing.
The iscsi2_session_setup change is very small. It adds
a argument to iscsi2_session_setup, and has it allocate some
private driver space based on that value. Only be2iscsi uses
the new arg in this patch. This change has been upstream
for a kernel release and is tested upstream as well has
here.
