Conflicts: kernel < 2.6.23

otherwise you end up with a non-functional system, because even the lo interface
cannot be brought up.
Comment 1 Marcela Mašláňová 2008-02-01 06:24:34 EST
Thank you for your report. The build of iproute is at the moment dependent on
the rhbz#431182. I hope that I'll build it soon with updated spec file.

Now I fix the building problem in rawhide, but add conflicts into spec isn't
Testcase on my computer:
rpm -q iproute kernel

but I have reported problems in KVM with
kernel-2.6.21 and iproute-2.6.23

Iproute should be backward compatible. Could you tell me more about versions,
which were tested and aren't working?
rpm -q kernel kernel-xen iproute
uname -a

I've hit the bug in current Rawhide in Xen.

    It seems it fails to properly detect that your kernel is missing
    RTM_NEWLINK support. Apparently the reason is that the kernels
    I tested with return a different error in this situation.

Happy testing.
