xenserver: Update interface-reconfigure and vif integration scripts.
This patch updates the versions of the host integration scripts to
what is present in the recent XCP update and the next release of
XenServer (5.6). I think it probably works on 5.5 as well but I
haven't verified that.
These new versions support runtime selection of the Linux bridging vs
vswitch through the toolstack. The patch includes the necessary
reconfiguration (rewriting /etc/xensource/network.conf) to enable
vswitch in the RPM %post stage.
The RPM spec file integration is only lightly tested, seems to work
for me.
This commit is as provided by Ian Campbell, with a few minor tweaks:
- Updated xenserver/automake.mk to distribute the added files.
- Updated RPM spec file not to complain if the added files do
not already exist (since they do not exist on XenServer 5.5.0).
- Change location of dbcache back to /var/lib/openvswitch/dbcache
so that this can coexist with our other internal builds.
(Undoubtedly we will have to adopt the new location chosen by Ian
eventually, however.)

sflow: Fix sFlow sampling structure.
According to Neil McKee, in an email archived at
http://openvswitch.org/pipermail/dev_openvswitch.org/2010-January/000934.html:
The containment rule is that a given sflow-datasource (sampler or
poller) should be scoped within only one sflow-agent (or
sub-agent). So the issue arrises when you have two
switches/datapaths defined on the same host being managed with
the same IP address: each switch is a separate sub-agent, so they
can run independently (e.g. with their own sequence numbers) but
they can't both claim to speak for the same sflow-datasource.
Specifically, they can't both represent the <ifindex>:0
data-source. This containment rule is necessary so that the
sFlow collector can scale and combine the results accurately.
One option would be to stick with the <ifindex>:0 data-source but
elevate it to be global across all bridges, with a global
sample_pool and a global sflow_agent. Not tempting. Better to
go the other way and allow each interface to have it's own
sampler, just as it already has it's own poller. The ifIndex
numbers are globally unique across all switches/datapaths on the
host, so the containment is now clean. Datasource <ifindex>:5
might be on one switch, whille <ifindex>:7 can be on another.
Other benefits are that 1) you can support the option of
overriding the default sampling-rate on an interface-by-interface
basis, and 2) this is how most sFlow implementations are coded,
so there will be no surprises or interoperability issues with any
sFlow collectors out there.
This commit implements the approach suggested by Neil.
This commit uses an atomic_t to represent the sampling pool. This is
because we do want access to it to be atomic, but we expect that it will
"mostly" be accessed from a single CPU at a time. Perhaps this is a bad
assumption; we can always switch to another form of synchronization later.

datapath: Fix build with kernel header layout recently adopted by Debian.
Recent Debian kernel-header packages divide kernel headers into two
directories: the "common" headers that are not architecture-specific,
which go in a directory named like
/usr/src/kernel-headers-2.6.31-1-common,
and architecture-specific headers in a directory named, e.g.
/usr/src/kernel-headers-2.6.31-1-686.
OVS needs to look at the ones in the "common" directory as part of its
configuration process, but the build directory provided on --with-l26 is
the architecture-specific directory. We also need the
architecture-specific directory, since it is the one that we use as part
of the "make", so we can't simply make the user specify the common
directory on --with-l26. Furthermore, there is no easy-to-see link
between the two directories, except as part of the text in a Makefile,
which is not the easiest language to parse.
This commit attempts to kluge around the problem by using the Debian
directory naming. If the build directory does not contain the headers,
then we replace the last component of its name by "-common" and check
for the headers there. This is not ideal, but it does solve the actual
problem at hand.
Tested with Debian's linux-headers-2.6.31-1-686 and with a few older
sets of headers that do not use this scheme.

xenserver: interface-reconfigure and vif hotplug relicensing.
As part of the Open Sourcing of xapi (the XenServer toolstack) via the
XenCloud project (announcement in [0]). The upstream versions of
interface-reconfigure and the vif hotplug script have been re-licensed
under an LGPL v2.1 + exception license. The exception applies to other
files in the upstream repository and doesn't particularly make sense for
these scripts but it is included to maintain the uniformity of the
license for the upstream repository.
This patch synchronises the licenses headers on those scripts with the
upstream version. Since those headers refer to a file called LICENSE in
the upstream repository I have included a copy here, slightly modified
to indicate precisely which files it applies to.
Git shows[1] that only myself and Nicira employees have made
modifications to these scripts in the openvswitch repository. The
licensing change has been okayed by Keith Amidon on behalf of Nicira.

Make ovs-appctl easier to use and synchronize its interface with ovs-vsctl.
It is inconvenient to type the whole path to the Unix daemon socket when
using ovs-appctl. Allow the name of the daemon to be used instead when
a pidfile exists in the default location, and contact ovs-vswitchd by
default.
Also, the various options for manipulating vlog were invented before the
general-purpose command mechanism existed. Get rid of all of the action
options in favor of just specifying the command to be executed as
non-option arguments.
Finally, there simply wasn't much value in allowing multiple targets or
options to be specified; these variations were never used in practice. So
simplify the interface by making it one target, one action per invocation.
Also, make ovs-vsctl use the same syntax for its --target option.
Based on work by Justin Pettit.

bonding: Ignore updelay if there is no active slave.
If all slaves on a bond are down but some are waiting for an updelay,
enable the slave with the shortest amount of delay remaining. This
would already occur if all other slaves were disabled at the time the
delay was to begin but not if a delay was already in progress. This
also immediately sends learning packets out in both situations, which
prevents incoming packets to disabled slaves from being blackholed.
