From: ebiederm@xxxxxxxxxxxx (Eric W. Biederman) Date: Sat, 08 Sep 2007 15:38:46 -0600 > > This patch introduces NETIF_F_NETNS_LOCAL a flag to indicate > a network device is local to a single network namespace and > should never be moved. Useful for pseudo devices that we > need an instance in each network namespace (like the loopback > device) and for any device we find that cannot handle multiple > network namespaces so we may trap them in the initial network > namespace. > > This patch introduces the function dev_change_net_namespace > a function used to move a network device from one network > namespace to another. To the network device nothing > special appears to happen, to the components of the network > stack it appears as if the network device was unregistered > in the network namespace it is in, and a new device > was registered in the network namespace the device > was moved to. > > This patch sets up a namespace device destructor that > upon the exit of a network namespace moves all of the > movable network devices to the initial network namespace > so they are not lost. > > Signed-off-by: Eric W.
