--- Begin Message ---Package: ifmetric Version: 0.3-4 Severity: normal Tags: patch Hi, My /etc/network/interfaces includes this: auto eth1 iface eth1 inet static address 192.168.0.2 netmask 255.255.255.0 metric 50 I don't have a network cable plugged in right now, so the link is down. When I run "ifup eth1" I get: NETLINK: Error: Invalid argument And the corresponding entry in the routing table is missing. This is due to this new check in Linux kernel 4.7 (also part of the stable series 4.4 at least): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=80610229ef7b26615dbb6cb6e873709a60bacc9f - ifmetric reads the original route, which contains RTNH_F_LINKDOWN flag - ifmetric deletes the original route - ifmetric modifies the metric - ifmetric tries to create the new modified route - the kernel rejects it because the RTNH_F_LINKDOWN flag shouldn't be set from userspace The fix is to clear RTNH_F_DEAD and RTNH_F_LINKDOWN. Patch attached.
