openflow: Add extension to flush CT by generic match.

2023-01-16T18:58:08+00:00

Add extension that allows to flush connections from CT
by specifying fields that the connections should be
matched against. This allows to match only some fields
of the connection e.g. source address for orig direction.

ofp-monitor: Support flow monitoring for OpenFlow 1.3, 1.4+.

2022-04-28T19:27:11+00:00

Extended OpenFlow monitoring support
* OpenFlow 1.3 with ONF extensions
* OpenFlow 1.4+ as defined in OpenFlow specification 1.4+.

ONF extensions are similar to Nicira extensions except for onf_flow_monitor_request{}
where out_port is defined as 32-bit number OF(1.1) number, oxm match formats are
used in update and request messages.

Flow monitoring support in 1.4+ is slightly different from Nicira and ONF
extensions.
 * More flow monitoring flags are defined.
 * Monitor add/modify/delete command is introduced in flow_monitor
   request message.
 * Addition of out_group as part of flow_monitor request message

Description of changes:
1. Generate ofp-msgs.inc to be able to support 1.3, 1.4+ flow Monitoring messages.
    include/openvswitch/ofp-msgs.h

2. Modify openflow header files with protocol specific headers.
    include/openflow/openflow-1.3.h
    include/openflow/openflow-1.4.h

3. Modify OvS abstraction of openflow headers. ofp-monitor.h leverages  enums
   from on nicira extensions for creating protocol abstraction headers. OF(1.4+)
   enums are superset of nicira extensions.
    include/openvswitch/ofp-monitor.h

4. Changes to these files reflect encoding and decoding of new protocol messages.
    lib/ofp-monitor.c

5. Changes to modules using ofp-monitor APIs. Most of the changes here are to
   migrate enums from nicira to OF 1.4+ versions.
    ofproto/connmgr.c
    ofproto/connmgr.h
    ofproto/ofproto-provider.h
    ofproto/ofproto.c

6. Extended protocol decoding tests to verify all protocol versions
        FLOW_MONITOR_CANCEL
        FLOW_MONITOR_PAUSED
        FLOW_MONITOR_RESUMED
        FLOW_MONITOR request
        FLOW_MONITOR reply
    tests/ofp-print.at

7. Modify flow monitoring tests to be able executed by all protocol versions.
    tests/ofproto.at

7. Modified documentation highlighting the change
    utilities/ovs-ofctl.8.in

Require Python 3 and remove support for Python 2.

2019-09-27T16:23:50+00:00

Python 2 reaches end-of-life on January 1, 2020, which is only
a few months away.  This means that OVS needs to stop depending
on in the next release that should occur roughly that same time.
Therefore, this commit removes all support for Python 2.  It
also makes Python 3 a mandatory build dependency.

Some of the interesting consequences:

- HAVE_PYTHON, HAVE_PYTHON2, and HAVE_PYTHON3 conditionals have
  been removed, since we now know that Python3 is available.

- $PYTHON and $PYTHON2 are removed, and $PYTHON3 is always
  available.

- Many tests for Python 2 support have been removed, and the ones
  that depended on Python 3 now run unconditionally.  This allowed
  several macros in the testsuite to be removed, making the code
  clearer.  This does make some of the changes to the testsuite
  files large due to indentation level changes.

- #! lines for Python now use /usr/bin/python3 instead of
  /usr/bin/python.

- Packaging depends on Python 3 packages.

Remove support for OpenFlow 1.6 (draft).

2019-02-05T17:21:19+00:00

ONF abandoned the OpenFlow specification, so that OpenFlow 1.6 will never
be completed.  It did not contain much in the way of useful features, so
remove what support Open vSwitch already had.

Add support for OpenFlow 1.5 statistics (OXS).

2018-05-16T22:29:46+00:00

This patch provides implementation Existing flow entry statistics are
redefined as standard OXS(OpenFlow Extensible Statistics) fields for
displaying the arbitrary flow stats.

To support this implementation below messages are newly added

OFPRAW_OFPT15_FLOW_REMOVED,
OFPRAW_OFPST15_AGGREGATE_REQUEST,
OFPRAW_OFPST15_FLOW_REPLY,
OFPRAW_OFPST15_AGGREGATE_REPLY,

The current commit adds support for the new feature in flow statistics
multipart messages, aggregate multipart messages and OXS support for flow
removal message, individual flow description messages.

ofp-packet: Better abstract packet-in format.

2018-03-14T18:34:41+00:00

This commit relieves the caller of code that deals with the format of
packet-in messages from some of the burden of understanding the packet
format.  It also renames the constants to appear to be at a higher level of
abstraction.
