Rich Lane 876e66e555 net: allow batch shutdown of multiple types of switches 
Each switch class will be called to shutdown its own instances.

Rich Lane 93cd5583eb IVSSwitch: support batch shutdown 
Not a single command like the OVS one, but it still greatly decreases the
shutdown time.

This does assume that stop() is called after batchShutdown(), which is true in
the current mininet code.

Gregory Gee 5cb4a5424d Add ability for for OVS switch start connect to controllers using protocols other than TCP. 
net.addController( 'c0', protocol='ssl' )

This now allows OVS to connect to a controller using SSL.  The default of protocol is 'tcp'
as it currently is.

Rich Lane a7eb557680 IVSSwitch: wait for ivs to terminate before tearing down node 
This was a problem when running IVS in a container. IVS would begin the process
of closing controller connections on receiving SIGTERM, but often mininet would
have continued on and removed the control network interface from the container
before it could send the FIN. The controller wouldn't know the connection had
been closed until it timed out much later.

Rich Lane 2200d8d173 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.

Rich Lane 0a54360211 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.

Bob Lantz 10be691b86 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.

Rich Lane 91261b2757 IVSSwitch: add support for dpctl 
dpctl is not included with IVS. The user will need to obtain it from the
OpenFlow reference repository.

kernel module.

Bob Lantz aa554d985d 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.
 2013-06-26 06:21:59 -07:00
Bob Lantz 804c4bbfa6 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...
