node: kill entire process group in terminate

mnexec already puts the shell into its own process group. Killing the entire
process group cleans up after any background processes the user left running.

Add tests for OVS user switch (skipping hifi test for now)

0a543602 07/19/2013 12:50 AM Rich Lane

IVSSwitch: support running IVS in a namespace

This change uses the `Node.cmd` method instead of `Popen`. The `cmd` method
sends the input to a shell which may be in another namespace (if --innamespace
is in use), while `Popen` would always run in the root namespace.

5c242637 07/18/2013 08:50 PM Rich Lane

clean: send SIGTERM before SIGKILL

IVS needs to be sent SIGTERM so it has a chance to clean up the kernel
datapath.

Fix issue with mountCgroups not recognizing mounted cgroup

Changed mountCgroups to use the file /proc/mounts (instead of the

Clean up intfs in root NS, and avoid deleting HW intfs

It appears that under certain conditions, such as when a
namespace exits, both ends of a veth pair may get dumped
into the root namespace. We therefore now remove an interface
both from its home namespace and from the root namespace.

71ffb002 07/01/2013 11:05 PM Rich Lane

IVSSwitch: remove namespace warnings

IVS works fine using --innamespace.

IVSSwitch: use ovs-ofctl for dpctl functionality

91261b27 06/28/2013 12:56 AM Rich Lane

IVSSwitch: add support for dpctl

dpctl is not included with IVS. The user will need to obtain it from the
OpenFlow reference repository.

test_hifi: use SWITCH to pick the switch class

27da832d 06/27/2013 09:50 PM Rich Lane

add support for the IVS virtual switch

IVS is an open source virtual switch available for download at
https://github.com/floodlight/ivs. It uses the openvswitch
kernel module.

Workaround: add default dpopts='--no-slicing' to UserSwitch

This disables slicing by default but fixes bandwidth limits.
Eventually we want to enable both to work together, but for now
this enables one or the other depending on the dpopts setting.

804c4bbf 06/26/2013 01:14 PM Bob Lantz

Workaround: add dpopts to UserSwitch

Currently, slicing on the user switch breaks bandwidth limits.
We don't yet have a good way of using both of them at the same time.
I'm inclined to turn off slicing by default, but I have to think
about it and also see if any one is using it...

topo: make new minimal Graph object a Graph, not a DiGraph

Fixes another Graph regression relative to NetworkX.

RipL broke because the NetworkX Graph object that was used previously
for topologies is an undirected graph:

import networkx as nx
g=nx.Graph()...

4e1630e1 06/20/2013 11:27 PM Brandon Heller

topo: add getitem for Graph

Commit 65c35b65 'Remove networkx dependency' broke this line from RipL:

nodes = [n for n in self.g[name] if self.layer(n)  layer]

To work around this, RipL code would have to be changed to something
like this:

nodes = [n for n in self.g.data[name] if self.layer(n)  layer]...

node: Make OVS switches reconnect quickly

Ordinarily, OVS switches back off when they can't reach their controllers.
Under the type of scenarios where Mininet is used, I think this is
probably just inconvenient. This patch set controllers to attempt to
reconnect every second.

153d598d 06/06/2013 11:23 PM Murphy McCauley

node: Allow OVSSwitch to run in userspace mode

This adds a datapath parameter to OVSSwitch which allows one to tell OVS to
run in userspace mode rather than kernel mode. From the commandline, this
is --switch=ovsk,datapath=user.

Note that this makes "ovsk" and the OVSKernelSwitch alias misnomers. Since...

topo: Add host count param to LinearTopo

Previously, LinearTopo took one parameter (k), which controlled the number
of switches; each of these got one host. This adds a second parameter (j),
which controls the number of hosts per switch, defaulting to 1 (as before)....

Change OVSSwitch.dpctl() to call ovs-ofctl

e5a15ced 03/29/2013 01:14 AM Bob Lantz

Change popen() to detach from terminal/process group.
This may or may not be the right thing to do - an alternative
would be to ignore SIGINT, but that would make the popen()
job unkillable by normal means! So we'll try this and see
how well it works.
Fixes #124

c771b2d7 03/24/2013 11:14 PM Bob Lantz

Add source node option to moveIntf() (note: low-level API!!)
In the future we may wish to enable moving interfaces across
nodes which are not in the root NS, and this would provide
the low-level mechanism to do so.

Change makeTerm() to tunnel X11 using socat if needed
For local display, allow local root access
For remote display, tunnel with socat/mnexec
This should enable wireshark in hosts and fix #119
