net: add ability to set names for outside links of veth devices When restoring a container crtools create veth pair inside it and then pushed one end to the namespaces crtools live in (outside). To facilitate the subsequent management of the otter end of the veth pair this option is added -- one can specifu a name by which the respective end would be visible.

Allow the veth-pair option to specify a bridge When restoring a pair of veth devices that had one end inside a namespace or container and the other end outside, CRIU creates a new veth pair, puts one end in the namespace/container, and names the other end from what's specified in the --veth-pair IN=OUT command line option. This patch allows for appending a bridge name to the OUT string in the form of OUT@<BRIDGE-NAME> in order for CRIU to move the outside veth to the named bridge. For example, --veth-pair eth0=veth1@br0 tells CRIU to name the peer of eth0 veth1 and move it to bridge br0. This is a simple and handy extension of the --veth-pair option that obviates the need for an action script although one can still do the same (and possibly more) if they prefer to use action scripts.

predump: Collect mnt and net namespaces properly On pre-dump we collect only two namespaces -- the mnt one for criu and mnt one again for root task. This is not correct. We need all mount namespaces to make the irmap generation work properly and we need all net namespaces to have parasite sockets created. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
