Management of network namespaces

Test case 1

Objective: Determine if NetworkManager, properly manages root namespace when started

Steps:

  1. Start NetworkManager

Expected state:

  1. In /var/run/netns there should be "rootns" file

Test case 2

Objective: Determine if NetworkManager, properly manages root namespace when stopped

Steps:

  1. Stop NetworkManager using Ctrl+C

Expected state:

  1. In /var/run/netns there shouldn't be "rootns" file anymore

Test case 3

Objective: Determine if NetworkManager properly creates a new network namespace

Steps:

  1. Start NetworkManager

  2. Invoke method over dbus to create a new network namespace:

dbus-send --system \
	--print-reply \
	--dest=org.freedesktop.NetworkManager \
	/org/freedesktop/NetworkManager/NetworkNamespacesController \
	org.freedesktop.NetworkManager.NetworkNamespacesController.AddNetworkNamespace \
	string:"testns"

Expected state:

  1. The expected response from method invocation should be like follows:
method return time=1455099674.081185 sender=:1.1046 -> destination=:1.1050 serial=2763 reply_serial=2
   object path "/org/freedesktop/NetworkManager/NetworkNamespace/1"

  1. In /var/run/netns there should be "testns" file

  2. Enter the network namespace and check that loopback interace is present and active:

ip netns exec testns bash
ip addr sh

TC3: Moving device to another namespace

Objective: Determine if NetworkManager properly registers that some device is moved to another network namespace

Steps:

  1. Start NetworkManager

Expected result: NetworkManager running

  1. Create new test device:
ip tuntap add dev tun0 mode tun

Expected result: new network device with name tun0 visible in root network namespace

  1. Create new network namespace:
dbus-send --system \
	--print-reply \
	--dest=org.freedesktop.NetworkManager \
	/org/freedesktop/NetworkManager/NetworkNamespacesController \
	org.freedesktop.NetworkManager.NetworkNamespacesController.AddNetworkNamespace \
	string:"testns"

Expected result: new network namespace visible using ip netns list

  1. Move device to the new network namespace:
ip link dev tun0 netns testns

Expected result: network manager removes device
