xenserver: use ovs-vsctl for VIF VLANs instead of separate state files
ovs-vsctl did not exist when this code was originally written, but it
provides exactly what is needed to get rid of those separate state
files.
The vif hotplug script diff is against the xs5.7 branch but I think is
applicable to master and/or citrix with just context changes.
I was thinking of using ovs-vsctl exclusively for configuration
modifications from the vif hotplug script but that would need a
mechanism to pass the additional vif details to ovs-vsctl add-port as
well as perhaps making the bridge optional to del-port. The other option
would be to use the --no-reload option and split the config mods into
two parts, but I don't like that idea much.

xenserver: Include bridge.*.xs-network-uuids for all networks
Previously I advised that only networks which were currently attached to
the host be listed in /etc/ovs-vswitchd.conf. However I've just realised
that this interacts badly with the slightly ugly special case used for
PIF.currently-attached when reading from dbcache instead of talking to
Xapi. This bites on boot when /etc/init.d/management-interface tries to
plug a selection of PIFs which are deemed to be somehow required by
xapi. (not helped by a bug in XenServer 5.7.0 which can cause this list
to be larger than it should be and not internally consistent).
For now I think it prudent to simply list all networks which could
potentially be attached to a given datapath, until I can figure out what
the sane fix is on the XenServer end.
(I think there are two options for a proper fix, either inspect the
current state of the network devices or assume dbcache represents the
desired final state after devices are plugged on boot. I'm leaning
towards the later since the dbcache should indicate the set of PIFs
which were attached on shutdown, which xapi will likely be trying to
replug on boot... Needs more thought though).

vswitch: Allow user to set Ethernet address of any internal interface.
Until now the vswitch configuration file has allowed the user to configure
the MAC address on bridge local ports only. This commit adds the ability
to configure them on any internal interface.
It would be logical to extend this to any bridge port, period, but many

vconn-unix: Unlink Unix sockets for vconns at close and free memory.
The make_unix_socket() function that Unix vconns use to create their
bindings calls fatal_signal_add_file_to_unlink() to make sure that the
binding socket gets unlinked from the file system if the process is killed
by a fatal signal. However, this doesn't happen until the process is
actually killed, even if the vconn that owns the socket is actually closed.
This wasn't a problem when the vconn-unix code was written, because all
of the unix vconns were created at process start time and never destroyed
during the normal process runtime. However, these days the vswitch can
create and destroy unix vconns at runtime depending on the contents of its
configuration file, so it's better to clean up the file system and free
the memory required to keep track of these sockets.
This commit makes unix vconns and pvconns delete their files and free
the memory used to track them when the (p)vconns are closed.

secchan: Better tolerate failing controller admission control in fail-open.
When the switch is configured to connect to a controller that accepts
connections, waits a few seconds, and then disconnects without setting up
flows, currently this causes "fail-open" to flush the flow table and
stop setting up new flows during the connection duration. This is OK if
it happens once, but it can easily happen every 8 seconds with typical

ovs-vsctl: additional commands for querying VLAN fake bridges.
Our test automation needs to be able to validate that a VLAN bridge and
for this I needed two new operations in ovs-vsctl:
* The ability to query the VLAN tag for a bridge.
* The ability to query the 'parent' of a bridge. The parent is the
non-VLAN/untagged bridge with the same physical devices and
could be a bond.
So given xenbr0 (containing eth0) + xapi2 (VLAN 42 on eth0) and xapi1
(containing bond0 == eth2+eth3) + xapi3 (VLAN 23 on the bonded
interface):
[root@warlock ~]# ovs-vsctl br-to-vlan xapi2
42
[root@warlock ~]# ovs-vsctl br-to-vlan xapi3
23
[root@warlock ~]# ovs-vsctl br-to-parent xapi2
xenbr0
[root@warlock ~]# ovs-vsctl br-to-parent xapi3
xapi1

vswitch: Correctly identify slave status in /proc compatibility layer
In the /proc compatibility layer, the bond member was reported as up
immediately after link recovery, regardless of the updelay. I believe
the compatibility code was correct if the check had been done with carrier,
but since 'iface->enabled' already does that calculation, we can use it
directly.
Additinally, when a bond slave was enabled or disabled, the bond
compatibility code was not being told to update its state. This commit
makes that call.

Raise MAC learning table capacity from 1,024 to 2,048 entries per bridge.
Given a possible 1,024 ports on a bridge the previous limit of 2,048
entries seems low.
If we want to increase this further we should introduce dynamic allocation
of table entries to avoid wasting memory in the common case.

/usr is the standard location for installation, so use that instead of our

One possibly surprising change is that the manpages listed in the %files

seems to be because RPM automatically compresses manpages, but only if they
are installed in a standard system location.

xenserver: Make RPM install work again.
The RPM install was generating a database cache in Python pickle format in
/etc/ovs-vswitchd.conf, but interface-reconfigure was looking for it in
XML format in /var/lib/openvswitch/dbcache. This fixes the problem, by
adding an init-dbcache command to interface-reconfigure and then using that
at RPM install time.
This moves the database cache creation from %pre to %post. This is
necessary so that interface-reconfigure is available from the install
script.

logging: Lower logging level for coverage messages due to slow poll loops
By default, many OVS processes keep track of their time through a poll
loop. If it takes an unusually long time (measured as some distance
from the mean), the processes will log stats it has been keeping about
coverage. It was doing this at level WARN.
On Xen systems, syslog messages written at level INFO and higher are
written to /var/log/messages synchronously. This would mean that there
would be dire messages that it took a few dozen milliseconds to go
through the loop, meanwhile, it would take up to 6(!) seconds writing
those. Meanwhile, the process would do no other processing, which could
be quite serious in the case of a process such as ovs-vswitchd.
This problem was somewhat masked because the time used by this logging
was not used in the calculations for determining how long it was taking
to get through the loop.
This commit lowers the default log level for those coverage messages to
INFO. On Xen systems, it raises the default level at which messages are
written to syslog to WARN.
Diagnosed and fixed with the help of Ian Campbell.
