This utility isn't going to be as portable as most of the Open vSwitch
utilities, unfortunately. I'm happy to take improvements to make it
able to work with, e.g., the "man" program from BSD. (I haven't tested
with that program, but I suspect that it is somewhat different from the
GNU version.)
The output of this program can already be viewed at:

Following patch adds support for userspace tunneling. Tunneling
needs three more component first is routing table which is configured by
caching kernel routes and second is ARP cache which build automatically
by snooping arp. And third is tunnel protocol table which list all
listening protocols which is populated by vswitchd as tunnel ports
are added. GRE and VXLAN protocol support is added in this patch.
Tunneling works as follows:
On packet receive vswitchd check if this packet is targeted to tunnel
port. If it is then vswitchd inserts tunnel pop action which pops
header and sends packet to tunnel port.
On packet xmit rather than generating Set tunnel action it generate
tunnel push action which has tunnel header data. datapath can use
tunnel-push action data to generate header for each packet and
forward this packet to output port. Since tunnel-push action
contains most of packet header vswitchd needs to lookup routing
table and arp table to build this action.

The option is documented for ovsdb-server but not for ovs-vswitchd.
This commit adds the documentation for ovs-vswitchd too.

This commit introduces multiple appctl commands (dpctl/*)
They are needed to interact with userspace datapaths (dpif-netdev), because the
ovs-dpctl command runs in a separate process and cannot see the userspace
datapaths inside vswitchd.
This change moves most of the code of utilities/ovs-dpctl.c in lib/dpctl.c.
Both the ovs-dpctl command and the ovs-appctl dpctl/* commands make calls to
lib/dpctl.c functions, to interact with datapaths.
The code from utilities/ovs-dpctl.c has been moved to lib/dpctl.c and has been
changed for different reasons:
- An exit() call in the old code made perfectly sense. Now (since the code
can be run inside vswitchd) it would terminate the daemon. Same reasoning
can be applied to ovs_fatal_*() calls.
- The lib/dpctl.c code _should_ not leak memory.
- All the print* have been replaced with a function pointer provided by the
caller, since this code can be run in the ovs-dpctl process (in which
case we need to print to stdout) or in response to a unixctl request (and
in this case we need to send everything through a socket, using JSON
encapsulation).
The syntax is
ovs-appctl dpctl/(COMMAND) [OPTIONS] [PARAMETERS]
while the ovs-dpctl syntax (which _should_ remain the same after this change)
is
ovs-dpctl [OPTIONS] (COMMAND) [PARAMETERS]

Too many users have incorrectly assumed that ovs-controller is a necessary
or desirable part of an Open vSwitch deployment. This commit should fix
the problem by renaming it test-controller and removing it from the
default install and from packaging.

We have a controller that puts many rules with different metadata values
into the flow table, where metadata is used (by "resubmit"s) to distinguish
stages in a pipeline. Thus, any given flow only needs to be hashed into
classifier "cls_table"s that contain a match for the flow's metadata value.
This commit optimizes the classifier lookup by (probabilistically) skipping
the "cls_table"s that can't possibly match.
(The "metadata" referred to here is the OpenFlow 1.1+ "metadata" field,
which is a 64-bit field similar in purpose to the "registers" defined by
Open vSwitch.)
Previous versions of this patch, with earlier versions of the controller in
question, improved flow setup performance by about 19%.
Bug #14282.

This python script summarizes ovs-dpctl dump-flows content by aggregating
the number of packets, total bytes and occurrence of the following fields:
- Datapath in_port
- Ethernet type
- Source and destination MAC addresses
- IP protocol
- Source and destination IPv4 addresses
- Source and destination IPv6 addresses
- UDP and TCP destination port
- Tunnel source and destination addresses
Testing included confirming both mega-flows and non-megaflows are
properly parsed. Bit masks are applied in the case of mega-flows
prior to aggregation. Test --script parameter which runs in
non-interactive mode. Tested syntax against python 2.4.3, 2.6 and 2.7.
Confirmed script passes pep8 and pylint run as:
pylint --disable=I0011 --include-id=y --reports=n
This tool has been added to these distribution:
- add ovs-dpctl-top to debian distribution
- add ovs-dpctl-top to rpm distribution.
- add ovs-dpctl-top to XenServer RPM.

The "stress" library was introduced years ago. We intended at the time to
start using it to provoke errors in testing, to make sure that Open vSwitch
was resilient against those errors. The intention was good, but there were
few actual implementations of stress options, and the testing never
materialized.
Rather than adapt the stress library for thread safety, this seems like a
good opportunity to remove it, so this commit does so.

--protocols allows configuration of the versions
that may be used when establishing an OpenFlow connection.
The default is 'OpenFlow10' which is consistent with
the behaviour prior to this patch.
The useful values at this time are:
'OpenFlow10', 'OpenFlow12', 'OpenFlow13',
Values may be combined in a comma delimited list.
e.g.: --protocols 'OpenFlow10,OpenFlow12,OpenFlow13'

These commands will be useful in a future commit that makes multiple
bridges share a single backing datapath. The ovs-dpctl commands will
show information about the backing datapath, so it will be difficult to
determine which information belongs to which bridge. The new "dpif/*"
ovs-appctl commands return information about the bridge--regardless of
how the backing datapath is configured.

ovs-l3ping is similar to ovs-test, but the main difference
is that it does not require administrator to open firewall
holes for the XML/RPC control connection. This is achieved
by encapsulating the Control Connection over the L3 tunnel
itself.
This tool is not intended as a replacement for ovs-test,
because ovs-test covers much broader set of test cases.
Sample usage:
Node1: ovs-l3ping -s 192.168.122.236,10.1.1.1 -t gre
Node2: ovs-l3ping -c 192.168.122.220,10.1.1.2,10.1.1.1 -t gre

I've had a few complaints that ovs-vswitchd logs its coverage counters
at WARN level, but this is mainly wrong: ovs-vswitchd only logs coverage
counters at WARN level when the "coverage/log" command is used through
ovs-appctl. This was even documented.
The reason to log at such a high level was to make it fairly certain that
these messages specifically requested by the admin would not be filtered
out before making it to the log. But it's even better if the admin just
gets the coverage counters as a reply to the ovs-appctl command. So that
is what this commit does.
This commit also improves the documentation of the ovs-appctl command.

This tool will be a replacement for the current ovs-vlan-test
utility. Besides from connectivity issues it will also be able
to detect performance related issues in Open vSwitch setups.
Currently it uses UDP and TCP protocols for stressing.

The version of groff on RHEL 5 doesn't include the .SY, .OP, or .YS macros
that ovs-benchmark.1 uses, so the manpage-check target fails on that
platform. This commit adds the groff definitions of those macros to a
file and includes it into ovs-benchmark.1.
I tested that this allows RHEL 5 to pass manpage-check.
|

This ensures that manpages actually get rebuilt if any of the lib/*.man
fragments that they depend upon are modified.
