Modules.Symvers update for open-iscsi

[mani.subramaniyan]

Has anybody come across this issue?

Since the downloaded open-iscsi's make or "make install" doesn't seem
to update the current kernel's Modules.symvers file (/usr/src/linux),
trying to add a new open-iscsi transport (similar to iscsi_tcp) leads
to link errors (symbol version mismatch...).
I deleted the open-iscsi symbols from the Modules.symvers file to
workaround this so I can build (in spite of LD warnings), and I can
load the newly built transport.
But the better way is to update the Modules files based on the kernel
we are building the open-iscsi for, right?
I believe OpenIB does this; if the make install option of open-iscsi
also takes care of this it will be great.
I can come up with a patch for this, if needed.

I saw this problem on SLES 10 with Open-iscsi 2.0.865-15 (semi-stable)
on x86_64 arch.

Thanks

This problem was discussed here a year ago:

http://groups.google.com/group/open-iscsi/browse_thread/thread/f6f87467967e3dd5#08abdcad25e0fd28

You can use the script that I attached to one of the messages in that thread. Instead, you can build a kernel with your transport (is it iSER?) and use the userspace code from open-iscsi.org (this is what I always do).

I hope it helps.

Hi Erez,
Thanks for the response. We did manage to do a patch. But the reason I
posted this was to say that many will have this same need of patching
and so it can be folded in to open-iscsi makefiles, so that it will
help a lot of people.

Our patch was also very similar to the one you pointed out, but we did
the patch before seeing this earlier post! (reinventing
unnecessarily..)

Thanks
