ofproto-dpif: Cleanup STP on ports when disabled on their bridge.
When STP is enabled on a bridge, the STP module puts its ports in
an STP_LISTENING state until STP converges. This causes all
traffic destined for these ports to be dropped. If STP is disabled
on the bridge, but not explicitly disabled on its ports, the bridge
fails to remove the STP state from these ports. Therefore, if a
port is in an STP_LISTENING state, it will remain in that state and
continue to drop all traffic indefinitely. This patch fixes the

configure: Try to extract kernel source directory from build Makefile.
OVS needs to inspect the headers in the kernel source directory at build
time. Debian keeps moving the source directory relative to the build
directory and doesn't provide an obvious way to find the source directory,
so in the past we've used some name-based heuristics to essentially guess
where it is.
This commit introduces a new heuristic that I hope will be more reliable:
extracting the source directory from the Makefile in the build directory.
In Debian's case, it looks like the Makefile generally contains a line of
the form "MAKEARGS := -C <srcdir> O=<outdir>". This commit extracts the
source directory from that line.
To avoid regressions this commit retains the older heuristics as fallbacks.

vswitchd: Always configure a default queue for QoS.
When an interface has QoS configured but no default queue (queue 0), OVS
has until now installed that QoS configuration literally, which causes all
packets destined for this default queue to be dropped. This behavior is
usually both unexpected and undesirable.
This commit changes behavior so that, when no default queue is configured,
OVS uses a default "empty" configuration for the default queue. This
behavior should be more acceptable when QoS is slightly misconfigured.
I tested that, without this patch, configuring only queue 1 causes "tc
class show" to show only queue 1 (handle 1:2) for linux-htb and linux-hfsc,
and that with this patch it shows configurations for both queue 0 (handle

tests: Reduce risk of port collision and remove bash dependency.
A few tests need a random TCP port on which to listen for connections.
Until now, the tests have used the $RANDOM bash extension to do this, but
this runs the risk of occasionally colliding with an in-use port. This
commit removes the bash dependency by switching to using a small Perl
program to pick random ports and reduces the risk of collision by
attempting to bind the port that it chooses.

ovs-xapi-sync: Always set iface-id, not just when xs-vif-uuid changes.
When XAPI moves an interface from one bridge to another, the vif script
removes the vif from one bridge and adds it to (possibly) a different
bridge in a single transaction. The new record does not have an iface-id
initially (because the vif script never adds the iface-id initially) but
it has the same name and xs-vif-uuid as the old one, so the caching logic
in ovs-xapi-sync failed to add a new iface-id. This commit fixes the
caching logic.
Observed on XenServer 5.6.100. It's possible that XAPI behavior changed in

mac-learning: Increase MAC learning timeout to 300 seconds.
When Cisco (and other?) routers are configured in high-availability modes,
they use two different MAC addresses. The router uses MAC 1 only for ARP
replies. The router uses MAC 2 for forwarding IP packets to end hosts.
When a MAC learning switch is attached to the router, therefore, it will
only learn the location of MAC 1 from ARP replies. If the end host's ARP
cache refresh timer is longer than the switch's MAC learning timeout, then
packets to the router will be flooded from the MAC learning timeout until
the next ARP reply.
This commit fixes the problem by increasing the MAC learning timeout from
60 seconds to 300 seconds. According to research by Sanjay Sane, this is
always sufficient, even with operating systems that use ARP timeouts
longer than 300 seconds (such as FreeBSD and Mac OS, which have 1200
seconds ARP timeouts) because the routers that cause this problem send
unsolicited ARP replies every 180 seconds.
This issue arises in any situation where traffic between two hosts flows
only in one direction. The explanation above describes only one special
case.
