lxc-user-nic is a setuid-root program with which unprivileged users
may manage network interfaces for use by a lxc container.
It will consult the configuration file /usr/local/etc/lxc/lxc-usernet
to determine the number of interfaces which the calling user is
allowed to create, and which bridge he may attach them to. It tracks
the number of interfaces each user has created using the file
/run/lxc/nics. It ensures that the calling user is privileged over
the network namespace to which the interface will be attached. lxc-
user-nic also allows one to delete network devices. Currently only
ovs ports can be deleted.
lxcpath
The path of the container. This is currently not used.
name The name of the container. This is currently not used.
pid The process id for the task to whose network namespace the
interface should be attached.
type The network interface type to attach. Currently only veth is
supported. With this type, two interfaces representing each
tunnel endpoint are created. One endpoint will be attached to
the specified bridge, while the other will be passed into the
container.
bridge The bridge to which to attach the network interface, for
instance lxcbr0.
container nicname
The desired interface name in the container. This will be eth0
if unspecified.
path to network namespace
A path to open to get a file descriptor for the target network
namespace. This is only relevant when an veth device is
deleted.
