Hi
It looks like conf.c:instanciate_veth() was rewritten; the result is
that lxc-start is failing when setting up the veth pair MTUs. I rewrote
a very small section of the code and it seems to be working fine now:
1) Move the following block (unchanged) before the block that's
getting/setting the MTU
< netdev->ifindex = if_nametoindex(veth2);
< if (!netdev->ifindex) {
< ERROR("failed to retrieve the index for %s", veth2);
< goto out_delete;
2) Replace
< mtu = netdev_get_mtu(if_nametoindex(netdev->link));
by
> mtu = netdev_get_mtu(netdev->ifindex);
The whole code diff is as follows:
# diff lxc-master/src/lxc/conf.c lxc-steph/src/lxc/conf.c
2602a2603,2608
> netdev->ifindex = if_nametoindex(veth2);
> if (!netdev->ifindex) {
> ERROR("failed to retrieve the index for %s", veth2);
> goto out_delete;
> }

< mtu = netdev_get_mtu(if_nametoindex(netdev->link));
---
> mtu = netdev_get_mtu(netdev->ifindex);

< }
<
< netdev->ifindex = if_nametoindex(veth2);
< if (!netdev->ifindex) {
< ERROR("failed to retrieve the index for %s", veth2);
< goto out_delete;
Was there a reason why the interface index was searched after the MTU
get/set which actually depends on the interface index?
Thanks
Stephane
