DEV_CHANGE_NET_NAMES(9) 				      Network device support					   DEV_CHANGE_NET_NAMES(9)

NAME

       dev_change_net_namespace - move device to different nethost namespace

SYNOPSIS

       int dev_change_net_namespace(struct net_device * dev, struct net * net, const char * pat);

ARGUMENTS

       dev
	   device

       net
	   network namespace

       pat
	   If not NULL name pattern to try if the current device name is already taken in the destination network namespace.

DESCRIPTION

       This function shuts down a device interface and moves it to a new network namespace. On success 0 is returned, on a failure a netagive
       errno code is returned.

       Callers must hold the rtnl semaphore.

NAME

       network_namespaces - overview of Linux network namespaces

DESCRIPTION

       Network namespaces provide isolation of the system resources associated with networking: network devices, IPv4 and IPv6 protocol stacks, IP
       routing tables, firewall rules, the /proc/net directory (which is a symbolic link to /proc/PID/net), the /sys/class/net directory,  various
       files under /proc/sys/net, port numbers (sockets), and so on.

       A physical network device can live in exactly one network namespace.  When a network namespace is freed (i.e., when the last process in the
       namespace terminates), its physical network devices are moved back to the initial network namespace (not to the parent of the process).

       A virtual network (veth(4)) device pair provides a pipe-like abstraction that can be used to create tunnels between network namespaces, and
       can  be	used to create a bridge to a physical network device in another namespace.  When a namespace is freed, the veth(4) devices that it
       contains are destroyed.

       Use of network namespaces requires a kernel that is configured with the CONFIG_NET_NS option.
