[Bug 26992] New: iscsi session re-establishment by client does not work (auth method rejected by target)

           Summary: iscsi session re-establishment by client does not work
                    (auth method rejected by target)
           Product: IO/Storage
           Version: 2.5
    Kernel Version: >=2.6.33
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: SCSI
        AssignedTo: linux-scsi@vger.kernel.org
        ReportedBy: bugzilla-kernel-org-sux2k0@mstier.de
                CC: bugzilla-kernel-org-sux2k0@mstier.de
        Regression: No


Latest client kernel version known to work: 2.6.32.27 (vanilla)
First client kernel version known NOT to work: 2.6.33 (vanilla)

I'm doing sanboot via iSCSI/TCP using gPXE 1.0.1 from etherboot.org. The gPXE
chain boot loader registers the iSCSI target lun as boot disk and when the
Ubuntu OS starts iscsid, session re-establishment fails when using kernel
2.6.33 or higher on the client (session startup configured as manual). Works
perfectly with 2.6.32.27 on the client.

The client machine uses open-iscsi v2.0-871 (Ubuntu 10.04/Lucid).

Tested against:
iscsi-target v1.4.20.2
and
stgt v1.0.12
(running on kernel 2.6.35.8)

FYI: to reproduce the bug, it should be sufficient to kill -KILL iscsid on the
client, and then restart it.

Are these kernel.org/open-iscsi.org open-iscsi tools ir distro build ones?

I think this is due to a sysfs issue. If I am right it should be fixed 
in 872 
(http://kernel.org/pub/linux/kernel/people/mnc/open-iscsi/releases/open-iscsi-2.0-872.tar.gz) 
or I think you can change the SYSFS DEPRECIATED and SYSFS V2 DEPRECIATED 
settings. I cannot remember if you need to turn it on or off (I think 
you need to turn it on with older tools). Send your .config.

Also could you send the log messages for when it fails? And does normal 
login work? If you just boot from a local drive and run iscsiadm to 
login does it fail? What is the error message and what is the 
/var/log/message output?

Thanks!

v872 works.

BTW: v872 is not available at open-iscsi.org/bits. Otherwise I would have found
it before filing this bug. :-)

I'll enter an Ubuntu bug -- maybe they didn't find it either.

Ah yeah, sorry about that. We are having trouble with access to 
open-iscsi.org. I cannot access it to update it, so I have been putting 
updates on http://kernel.org/pub/linux/kernel/people/mnc/open-iscsi/.
