* | [NETNS][IPV6] addrconf - make addrconf per namespaceBenjamin Thery2008-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the infrastructure to propagate the network namespace information is ready. Make use of it. There is a special case here between the initial network namespace and the other namespaces: * When ipv6 is initialized at boot time (aka in the init_net), it registers to the notifier callback. So addrconf_notify will be called as many time as there are network devices setup on the system and the function will add ipv6 addresses to the network devices. But the first device which needs to have its ipv6 address setup is the loopback, unfortunatly this is not the case. So the loopback address is setup manually in the ipv6 init function. * With the network namespace, this ordering problem does not appears because notifier is already setup and active, so as soon as we register the loopback the ipv6 address is setup and it will be the first device.
