iscsitarget-dkms package won't compile kernel module

[Martin]

I'm trying to set up a Raspberry Pi running Raspbian Jessie as an iSCSI-target but installing the package iscsitarget-dkms yields the following error:

make KERNELRELEASE=4.1.13-v7+ -C /lib/modules/4.1.13-v7+/build M=/var/lib/dkms/iscsitarget/1.4.20.3+svn502/build........(bad exit status: 2)
Error! Bad return status for module build on kernel: 4.1.13-v7+ (armv7l)
Consult /var/lib/dkms/iscsitarget/1.4.20.3+svn502/build/make.log for more information.

I attached the make.log file.

The patch at https://github.com/openembedded/meta-openembedded/blob/master/meta-networking/recipes-extended/iscsitarget/files/fix-errors-observed-with-linux-3.19-and-greater.patch looks promising. However, I have yet to try this patch.

How did you get/setup the /usr/src/linux-headers-4.1.13-v7+ directory (and contents)?
Be as specific as you can be.

[Diederik (didi-debian)]

And have you tried it with the patch applied? Did that change anything?

[Diederik (didi-debian)]

Just found https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=786611 and that seems to confirm your issue.

And I have just been able to confirm the issue myself, see the attached iscsitarget.build.log

With the attached patch, from the link in the OP, you can get it to compile, although with several warnings.

The question is whether you want to use this, because the driver seems to be in a BAD state. Trying to compile it on my host PC (Debian Sid, amd64) failed horribly and the linked Debian bug is mostly about abandoning the driver (and possible take over of maintainership).

If you're REALLY interested in this driver, you should try to activate upstream first. If that fails, which has a reasonable chance, you could try to fork it and put the code on GitHub/GitLab for example and start working on it and try to find other people interested in this driver to help you with it.
When you do, please also work on the Makefile so it's easy to compile for different kernel versions ;-)

Also linked to the ubuntu package:
https://bugs.launchpad.net/ubuntu/+source/iscsitarget

And there you can see several BIG bugs (too).

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "deb-bug786611.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

Linking it with the Ubuntu package has consequences which I don't understand, thus I removed the bug link.
But in message 8 you can still see the link so you can see/follow the status/bugs there too.
