Hi, after Updating my Gentoo-System yesterday the Network didn't start up any longer. For each Interface there were RTNETLINK: Invalid Argument errors. When issuing ifconfig -a all Interfaces were there and configured OK (i.e. IP Address was set); however, I was unable to get a link. Issuing a ifconfig eth0|eth1|lo up brought up the Interfaces. I then reverted my /etc/conf.d/net to use ifconfig and the System almost started up, however, lo was not up, i.e. "ping localhost" didn't work. I added a "ifconfig lo up" at the end of the start-Function in /etc/nit.d/net.lo and then also got Loopback during start. However, my Xen Domains didn't start -- the came up with the status "P" and then died after a while. I then reverted to sys-apps/iproute2-2.6.22.20070710 and the System bootet fine, i.e. I re-commented the #modules=( "iproute2" ) and removed my "ifconfig lo up" code from /etc/init.d/net.lo and the System still came up 1a, incl. the Xen Domains. I checked /etc/conf.d/net.examples but it was dated 01/24/08. I also checked /var/log/portage/elog/summary.log to look if I forgot a Migration-step but didn't find any. The System runs on Gentoo since ~2005, so probably I did forgot a Migration-Step at any time in the Past that leads to this desastrous result -- however, I have no idea where to look. Reproducible: Always Steps to Reproduce: 1. Emerge to the iproute2-2.6.23.20071016.ebuild 2. Restart the System Actual Results: Network Interfaces are not being brought up. Expected Results: The Interfaces should be brought up. When "downgrading" iproute2 Networking runs fine again.
Attach your /etc/conf.d/net here and post emerge --info output; thanks.

Created attachment 146401 [details] emerge --info Hi, here's my /etc/conf.d/net and the output of emerge --info. Sorry, I should at least have included the last. Cheers, _ralf_
Same here. After upgrading to iproute2-2.6.23.20071016 all interfaces are configured, but not brought up. Every call of /etc/init.d/net.* shows a lot of "RTNETLINK answers: Invalid argument"-Errors. Calling "ip link set lo up" from bash returns also a "RTNETLINK answers: Invalid argument"-error, "ifconfig lo up" works fine. I think this is only a bug in iproute2 and not related to any init-scripts. sys-apps/iproute2-2.6.23.20071016 should be masked meanwhile. Using this version on a remote box without physical access locks you out.
I yesterday updated my @home System; on that maschine, the iproute2-2.6.23-20071016 indeed does work 1a. Not sure, maybe a Kernel-related issue (on the machine where the problem occured I tried Kernels 2.6.21-xen, 2.6.20-r2-xen, and 2.6.18-gentoo, i.e. 2 Xen Kernels and one rather old "normal" Kernel). On the @home-Machine I don't use Xen and it runs with Kernel 2.6.24-gentoo-r3.
One more note: On my @home-System, to check my assumption the Problem is Kernel-related I just emerged & compiled a 2.6.19-gentoo-r5 Kernel. Upon booting this "old" Kernel I got exactly the same errors (i.e, RTNETLINK: invalid argument and no usable Interfaces) as on the Xen-Host @work. So it seems the "new" iproute2 needs either a more recent Kernel OR some feature turned on on an "old" Kernel...
Confirmed here. Working configuration: sys-apps/iproute2-2.6.22.20070710 sys-kernel/xen-sources-2.6.20-r6 or: sys-apps/iproute2-2.6.23.20071016 sys-kernel/gentoo-sources-2.6.23-r8 Not working configuration: sys-apps/iproute2-2.6.23.20071016 sys-kernel/xen-sources-2.6.20-r6 Vincent
I confirm also: everything works fine for me with: sys-apps/iproute2-2.6.22.20070710 sys-kernel/gentoo-sources-2.6.19-r5 and I get "RTNETLINK: Invalid Argument" errors if I upgrade to sys-apps/iproute2-2.6.23.20071016 (same kernel, which I cannot upgrade for other reasons) (In reply to comment #7) > Confirmed here. > Working configuration: > > sys-apps/iproute2-2.6.22.20070710 > sys-kernel/xen-sources-2.6.20-r6 > or: > sys-apps/iproute2-2.6.23.20071016 > sys-kernel/gentoo-sources-2.6.23-r8 > > Not working configuration: > > sys-apps/iproute2-2.6.23.20071016 > sys-kernel/xen-sources-2.6.20-r6 > > Vincent >
re-open if iproute2-2.6.24.20080108 doesnt work
