Now we have three parts related with tgt in -mm kernels (through
scsi-target git tree).
o tgt core : we have only one not-merged patch in the svn tree
o ibmvscsi target driver
o libsrp : provides SRP library functions, ibmvscsi target driver
depends on this
So almost everything that ibmvscsi target driver needs is in -mm
About iSCSI (and iSER), we need three following parts in addition to
the above parts.
o libiscsi : we add to target support to the current code.
o scsi_transport_iscsi : ditto
o iscsi_tcp : we takes initiator specific stuff out of this and move
it to iscsi_tcp_initiator.
o iscsi_tcp_initiator : see above
o iscsi_tcp_target : provies target specific stuff
You can see them at:
They got a bit out of data. They are based on open-iscsi r596 code.
Mike has been reviewing them and we will post them to scsi-ml. We need
to get permission to put them into mainline.
iSER needs modifications to libiscsi and iscsi_iser. Possibly, we have
something like iscsi_target.
About schedule, please ask James. :) I think that tgt core and
ibmvscsi driver is not so far. Andrew said last month, "SCSI target
patches are being worked on - perhaps a 2.6.18/2.6.19 feature" (though
we already missed 2.6.18).

I made the tgt patch for 2.6.17. Would it help?
Sorry. There is no instruction about it yet. I will write something
As you said, it's complicated to run tgt right now. I've been working
on it because some people might be interested in tgt after OLS. I want
to make sure that everyone can run tgt without effort. I'm in the
middle of large user-space rewrite (I've commited some last night).
Sorry for delay about iSER tgt stuff. I will work on it after OLS. If
you guys teach me how to setup Chelsio T3 at OLS, I can work on it
right after OLS. :)
