The tcpdump output format differs slightly from one version to another, so
this test that runs tcpdump would fail depending on the system it was run
on. This commit fixes the problem by using "sed" to trim off the part of
the line that can differ.

cls_rule_format() prints register values are printed in hex, but the "load"
action was printing them in decimal. This makes it consistent.

Bug #4249.
It's become clear over the past few weeks that some people really depend
on the formatting of ofp-print output. It has also become clear that OVS
doesn't have anything that actually checks or enforces the formatting of
the output. The former is not something I want to encourage, but the
latter is somewhat worrisome because the formatting does change from time
to time and I want to make sure that that is intentional.
So this commit adds at least one test for each supported OpenFlow and
Nicira extension message, so that we can better keep track of changes.
The tests have been failing for a few days now, because the PKI expired a
few days into 2011. This commit instead generates the PKI at "make check"
time, which has the additional benefit of getting some test exposure for
the ovs-pki program.

We have a need to identify tunnels with keys longer than 32 bits. This
commit adds basic datapath and OpenFlow support for such keys. It doesn't
actually add any tunnel protocols that support 64-bit keys, so this is not
very useful yet.
The 'arg' member of struct odp_msg had to be expanded to 64-bits also,
because it sometimes contains a tunnel ID. This member also contains the
argument passed to ODPAT_CONTROLLER, so I expanded that action's argument
to 64 bits also so that it can use the full width of the expanded 'arg'.
Userspace doesn't take advantage of the new space though (it was only
using 16 bits anyhow).
This commit has been tested only to the extent that it doesn't disrupt
basic Open vSwitch operation. I have not tested it with tunnel traffic.

Feature #3976.
This fixes OpenFlow 1.0 flow stats reporting of flows added via NXM.
I noticed this problem while implementing 64-bit tunnel IDs, hence the
positioning. The following commit adds a test.

"ovs-ofctl del-flows br0" segfaulted because do_flow_mod__() assumed that
it always had a "flow" argument, which is not true for the del-flows
command.
Beyond that, parse_ofp_flow_mod_str() rejected "ovs-ofctl del-flows
br0" because no actions were supplied, even though supplying actions
doesn't make sense for deleting flows.
This commit fixes both problems and adds a simple test that would have
caught both problems.
Bug #4112.
Open vSwitch contains a few different chunks of code that need to decode
an OpenFlow message to determine its type and then validate that it is
long enough. Until now, the code for doing this has been more or less
scattered across the tree. Whenever a new piece of code needed to do this,
it generally needed to reimplement at least part of it.
This commit centralizes all of that work into a single function,
ofputil_decode_msg_type(), and helper functions, and converts all of the
code that was decoding messages by hand to use the new function.
Since the Nicira Extended Match was specified nicira-ext.h has claimed that
arbitrary masks are allowed, but in fact only certain masks were actually
implemented. This commit implements general masking for the 802.1Q VLAN
TCI field.
Originally, wildcards were just the OpenFlow OFPFW_* bits. Then, when
OpenFlow added CIDR masks for IP addresses, struct flow_wildcards was born
with additional members for those masks, derived from the wildcard bits.
Then, when OVS added support for tunnels, we added another bit
NXFW_TUN_ID that coexisted with the OFPFW_*. Later we added even more bits
that do not appear in the OpenFlow 1.0 match structure at all. This had
become really confusing, and the difficulties were especially visible in
the long list of invariants in comments on struct flow_wildcards.
This commit cleanly separates the OpenFlow 1.0 wildcard bits from the
bits used inside Open vSwitch, by defining a new set of bits that are
used only internally to Open vSwitch and converting to and from those
wildcard bits at the point where data comes off or goes onto the wire.
It also moves those functions into ofp-util.[ch] since they are only for
dealing with OpenFlow wire protocol now.
The flow_from_match() and flow_to_match() functions have to deal with most
of the state in a cls_rule anyhow, and this will increase in upcoming
commits, to the point that we might as well just use a cls_rule anyhow.
This commit therefore deletes flow_from_match() and flow_to_match(),
integrating their code into cls_rule_from_match() and the new function
cls_rule_to_match(), respectively. It also changes each of the functions'
callers to use the new cls_rule_*() function.
When CLS_CURSOR_FOR_EACH(_SAFE) iterated through a classifier, the
cls_cursor_next() function did not properly handle the case where there was
more than a single rule on a list. This commit fixes the problem.
The addition to the testsuite would have found the problem earlier.

The wrong prerequisite function was being called for set-br-external-id, so
it didn't set up to monitor the right columns, so an assertion failed.
This fixes the problem.
Also, change the test for external IDs so that it will find the regression.
(Running all of the ovs-vsctl commands together caused the column to be
monitored due to another command's intervention.)

Bug #4095.
Until now, by default the IDL replicated all tables and all columns in the
database, and a few functions made it possible to avoid replicating
selected columns. This commit adds a mode in which nothing is replicated
by default and the client code is responsible for specifying each column
and table that it is interested in. The following commit adds a user for
this mode.
Our controller group at Nicira has requested a way to annotate flows with
extra information beyond the flow cookie. The new NXAST_NOTE action
provides such a way.
This new action is somewhat controversial. Some have suggested that it
should be added another way (either as part of the Nicira Extended Match
or as a new component of the flow_mod and related messages). Others think
that it has no place in the OpenFlow protocol at all and that an equivalent
should be implemented using the already available features of OVSDB. So
it is possible that this extension will be deleted and the feature will
be reimplemented some other way (or not at all).

This type and these parameters were useful when ofproto had the need to
separately traverse exact-match rules looking for subrules, but it no
longer does that because subrules (now called "facets") are not kept in
the classifier any longer. All the callers are now passing CLS_INC_ALL
anyhow, so we might as well delete this feature and simplify the code.
Many Open vSwitch tests fail on Debian's automatic build machines because
the builds occur in deeply nested directories with long names. OVS tries
to bind and connect to Unix domain sockets using absolute path names, which
in combination with long directory names means that the socket's name
exceeds the limit for Unix domain socket names (108 bytes on Linux).
This commit works around the problem on Linux by indirecting through
/proc/self/fd/<dirfd>/<basename> when names exceed the maximum that can be
used directly.
