secchan: Make sure fail-open doesn't drop the first messages from connection.

Fail-open mode is entered or left in a secchan "periodic" callback, which
may not be called immediately after the connection to the controller
actually comes up.  This can cause the fail-open local-packet CB to
locally handle messages from the datapath and drop them, causing the
controller to think that it's being ignore and drop the connection.

16 years agoRework STP implementation in controller.
Ben Pfaff [Tue, 14 Oct 2008 23:48:47 +0000 (16:48 -0700)]
Rework STP implementation in controller.

Before, we tried to use the port configuration bits to implement STP; e.g.
if a port was in LISTEN state we turned off sending and receiving frame
other than BPDUs.  Unfortunately this interacts very badly with in-band
control: when the switch connects to the controller, it can be connected
to the controller over a port that is not in FORWARD, and so then the
controller disabled that port, and the connection eventually dropped when
an echo request/reply failed to get through.

Now, we implement STP by querying the flows on the switch and killing
off the ones that STP does not allow.  This works much better because,
although we still kill off the in-band control connection, the in-band
hook in secchan is then able to resurrect it.

--no-stp is still the default since this has not been tested very much.
