*** This bug is a duplicate of bug 930962 *** https://bugs.launchpad.net/bugs/930962 Hi Robert, so you'd say this was a bug in lxc versus linux because lxc should detect the kernel version and add this iptables rule in lxc-net.conf? I guess I don't really see a downside to that... -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1254338 Title: lxc containers failing dhcp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1254338/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Indeed - running sudo iptables -t mangle -A POSTROUTING -o lxcbr0 -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill In the host permits networking to work correctly. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1254338 Title: lxc containers failing dhcp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1254338/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Adding
iptables -t mangle -A POSTROUTING -o ${LXC_NETWORK} -p udp -m udp
--dport 68 -j CHECKSUM --checksum-fill
to /etc/init/lxc-net.conf
will fix it on boot for anyone suffering this - I'm happy to wrap that
up in a debdiff if this is considered an appropriate fix.

I can see this: dhcp3 (3.1.3-2ubuntu3.5) lucid-proposed; urgency=low * Include patch from RedHat/Fedora to deal with hardware/xen/virtio offload of UDP checksums. (LP: #930962) * Update apparmor profile to add required the network packet raw rule for the checksum change. -- Stéphane Graber stgra...@ubuntu.com Thu, 23 May 2013 19:58:28 -0400 In the dhcp3-client changelog, but this won't help anyone with existing containers: surely the thing to do is to wait for that to be in the default for all new containers (e.g. 5 years) then remove the checksum-fill support? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1254338 Title: lxc containers failing dhcp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1254338/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
