# SYNOPSIS:
|
|
# netns_comm.sh <NS_EXEC_PROGRAM> <IP_VERSION> <COMM_TYPE>
|
|
#
|
|
# OPTIONS:
|
|
# * NS_EXEC_PROGRAM (ns_exec|ip)
|
|
# Program which will be used to enter and run other commands
|
|
# inside a network namespace.
|
|
# * IP_VERSION (ipv4|ipv6)
|
|
# Version of IP. (ipv4|ipv6)
|
|
# * COMM_TYPE (netlink|ioctl)
|
|
# Communication type between kernel and user space
|
|
# for basic setup: enabling and assigning IP addresses
|
|
# to the virtual ethernet devices. (Uses 'ip' command for netlink
|
|
# and 'ifconfig' for ioctl.)
|
|
#
|
|
# Tests that a separate network namespace can configure and communicate
|
|
# over the devices it sees. Tests are done using netlink(7) ('ip' command)
|
|
# or ioctl(2) ('ifconfig' command) for controlling devices.
|
|
#
|
|
# There are three test cases:
|
|
# 1,2. communication over paired veth (virtual ethernet) devices
|
|
# from two different network namespaces (each namespace has
|
|
# one device)
|
|
# 3. communication over the lo (localhost) device in a separate
|
|
# network namespace
