I added a

make user
make user install

to git the other day because I hit the same problem. I did not make it 
the default, because I was thinking most users are using older kernels 
and if they are grabbing the tarballs on open-iscsi.prg want the updated 
kernel modules built.

Is this ok?

What about splitting up the kernel from the userspace parts in different 
tarballs/trees?

Actually your info helps a lot.

I'll try the git code in the enviroment test.

Thank you !!!

Hi mike, if we are already at the subject. Something I wanted for a while.

It is expected for out-of-tree Kernel modules to constantly break at the
development edge. What happens today is that I can't finish compiling and
installing user-mode tools, if Kernel does not compile.

I want to submit a patch that will not force Kernel module compilation
by default, but only if say we do "make kernel". Since for me 99% of the
time I just want to update on the user-mode, and I'm using the Kernel
modules that come from the Kernel I'm using. Is that OK?

Boaz

Yeah, that is not going to work, because the 2.6.28 kernel changed some 
kernel APIs. The kernel modules need to be updated for the new APIs. I 
have done this to the code in git:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/mnc/open-iscsi.git

I am preparing to do a new release when I finish up integrating some 
patches from Fedora, converting code to use strlcat and strlcpy, and fix 
some bugs in the iface printing code. I was planning on having this done 
by 2.6.29 (so the new release will have 2.6.28 and .29 support). I know 
this does not help you much.

But the upstream 2.6.28.2 kernel is up to date with 870.1 (.2 just has 
one fix that 2.6.28 does not for memory leak), so you could just use 
those kernel modules and then use the userspace tools from 
open-iscsi-2.0-870.2 and you would probably be fine.
