10 * New upstream version
11 - Dropped support for Python older than version 2.7. As a consequence,
12 using Open vSwitch 2.5 or later on XenServer 6.5 or earlier (which
13 have Python 2.4) requires first installing Python 2.7.
15 * Group chaining (where one OpenFlow group triggers another) is
17 * OpenFlow 1.4+ "importance" is now considered for flow eviction.
18 * OpenFlow 1.4+ OFPTC_EVICTION is now implemented.
19 * OpenFlow 1.4+ OFPTC_VACANCY_EVENTS is now implemented.
20 * OpenFlow 1.4+ OFPMP_TABLE_DESC is now implemented.
21 * Allow modifying the ICMPv4/ICMPv6 type and code fields.
22 * OpenFlow 1.4+ OFPT_SET_ASYNC_CONFIG and OFPT_GET_ASYNC_CONFIG are
25 * New "out_group" keyword for OpenFlow 1.1+ matching on output group.
27 * Geneve tunnels can now match and set options and the OAM bit.
28 * The nonstandard GRE64 tunnel extension has been dropped.
29 - Support Multicast Listener Discovery (MLDv1 and MLDv2).
30 - Add 'symmetric_l3l4' and 'symmetric_l3l4+udp' hash functions.
31 - sFlow agent now reports tunnel and MPLS structures.
32 - New 'check-system-userspace', 'check-kmod' and 'check-kernel' Makefile
33 targets to run a new system testsuite. These tests can be run inside
34 a Vagrant box. See INSTALL.md for details
35 - Mark --syslog-target argument as deprecated. It will be removed in
37 - Added --user option to all daemons
38 - Add support for connection tracking through the new "ct" action
39 and "ct_state"/"ct_zone"/"ct_mark"/"ct_label" match fields. Only
40 available on Linux kernels with the connection tracking module loaded.
41 - Add experimental version of OVN. OVN, the Open Virtual Network, is a
42 system to support virtual network abstraction. OVN complements the
43 existing capabilities of OVS to add native support for virtual network
44 abstractions, such as virtual L2 and L3 overlays and security groups.

48 openvswitch (2.4.0-1) unstable; urgency=low
50 * New upstream version
51 - Flow table modifications are now atomic, meaning that each packet
52 now sees a coherent version of the OpenFlow pipeline. For
53 example, if a controller removes all flows with a single OpenFlow
54 "flow_mod", no packet sees an intermediate version of the OpenFlow
55 pipeline where only some of the flows have been deleted.
56 - Added support for SFQ, FQ_CoDel and CoDel qdiscs.
57 - Add bash command-line completion support for ovs-vsctl Please check
58 utilities/ovs-command-compgen.INSTALL.md for how to use.
59 - The MAC learning feature now includes per-port fairness to mitigate
61 - New support for a "conjunctive match" OpenFlow extension, which
62 allows constructing OpenFlow matches of the form "field1 in
63 {a,b,c...} AND field2 in {d,e,f...}" and generalizations. For details,
64 see documentation for the "conjunction" action in ovs-ofctl(8).
65 - Add bash command-line completion support for ovs-appctl/ovs-dpctl/
66 ovs-ofctl/ovsdb-tool commands. Please check
67 utilities/ovs-command-compgen.INSTALL.md for how to use.
68 - The "learn" action supports a new flag "delete_learned" that causes
69 the learned flows to be deleted when the flow with the "learn" action
71 - Basic support for the Geneve tunneling protocol. It is not yet
72 possible to generate or match options. This is planned for a future
73 release. The protocol is documented at
74 http://tools.ietf.org/html/draft-gross-geneve-00
75 - The OVS database now reports controller rate limiting statistics.
76 - sflow now exports information about LACP-based bonds, port names, and
77 OpenFlow port numbers, as well as datapath performance counters.
78 - ovs-dpctl functionality is now available for datapaths integrated
79 into ovs-vswitchd, via ovs-appctl. Some existing ovs-appctl
80 commands are now redundant and will be removed in a future
81 release. See ovs-vswitchd(8) for details.
83 * OpenFlow 1.4 bundles are now supported for flow mods and port
84 mods. For flow mods, both 'atomic' and 'ordered' bundle flags
85 are trivially supported, as all bundled messages are executed
86 in the order they were added and all flow table modifications
87 are now atomic to the datapath. Port mods may not appear in
88 atomic bundles, as port status modifications are not atomic.
89 * IPv6 flow label and neighbor discovery fields are now modifiable.
90 * OpenFlow 1.5 extended registers are now supported.
91 * The OpenFlow 1.5 actset_output field is now supported.
92 * OpenFlow 1.5 Copy-Field action is now supported.
93 * OpenFlow 1.5 masked Set-Field action is now supported.
94 * OpenFlow 1.3+ table features requests are now supported (read-only).
95 * Nicira extension "move" actions may now be included in action sets.
96 * "resubmit" actions may now be included in action sets. The resubmit
97 is executed last, and only if the action set has no "output" or "group"
99 * OpenFlow 1.4+ flow "importance" is now maintained in the flow table.
100 * A new Netronome extension to OpenFlow 1.5+ allows control over the
101 fields hashed for OpenFlow select groups. See "selection_method" and
102 related options in ovs-ofctl(8) for details.
103 - ovs-ofctl has a new '--bundle' option that makes the flow mod commands
104 ('add-flow', 'add-flows', 'mod-flows', 'del-flows', and 'replace-flows')
105 use an OpenFlow 1.4 bundle to operate the modifications as a single
106 atomic transaction. If any of the flow mods in a transaction fail, none
107 of them are executed. All flow mods in a bundle appear to datapath
108 lookups simultaneously.
109 - ovs-ofctl 'add-flow' and 'add-flows' commands now accept arbitrary flow
110 mods as an input by allowing the flow specification to start with an
111 explicit 'add', 'modify', 'modify_strict', 'delete', or 'delete_strict'
112 keyword. A missing keyword is treated as 'add', so this is fully
113 backwards compatible. With the new '--bundle' option all the flow mods
114 are executed as a single atomic transaction using an OpenFlow 1.4 bundle.
115 - ovs-pki: Changed message digest algorithm from MD5 to SHA-1 because
116 MD5 is no longer secure and some operating systems have started to disable
118 - ovsdb-server: New OVSDB protocol extension allows inequality tests on
119 "optional scalar" columns. See ovsdb-server(1) for details.
120 - ovs-vsctl now permits immutable columns in a new row to be modified in
121 the same transaction that creates the row.
122 - test-controller has been renamed ovs-testcontroller at request of users
123 who find it useful for testing basic OpenFlow setups. It is still not
124 a necessary or desirable part of most Open vSwitch deployments.
125 - Support for travis-ci.org based continuous integration builds has been
126 added. Build failures are reported to build@openvswitch.org. See INSTALL.md
127 file for additional details.
128 - Support for the Rapid Spanning Tree Protocol (IEEE 802.1D-2004).
129 The implementation has been tested successfully against the Ixia Automated
130 Network Validation Library (ANVL).
131 - Stats are no longer updated on fake bond interface.
132 - Keep active bond slave selection across OVS restart.
133 - A simple wrapper script, 'ovs-docker', to integrate OVS with Docker
134 containers. If and when there is a native integration of Open vSwitch
135 with Docker, the wrapper script will be retired.
136 - Added support for DPDK Tunneling. VXLAN, GRE, and Geneve are supported
137 protocols. This is generic tunneling mechanism for userspace datapath.
138 - Support for multicast snooping (IGMPv1, IGMPv2 and IGMPv3)
139 - Support for Linux kernels up to 4.0.x
140 - The documentation now use the term 'destination' to mean one of syslog,
141 console or file for vlog logging instead of the previously used term
143 - Support for VXLAN Group Policy extension
144 - Initial support for the IETF Auto-Attach SPBM draft standard. This
145 contains rudimentary support for the LLDP protocol as needed for
147 - The default OpenFlow and OVSDB ports are now the IANA-assigned
148 numbers. OpenFlow is 6653 and OVSDB is 6640.
149 - Support for DPDK vHost.
150 - Support for outer UDP checksums in Geneve and VXLAN.
151 - The kernel vports with dependencies are no longer part of the overall
152 openvswitch.ko but built and loaded automatically as individual kernel
153 modules (vport-*.ko).
154 - Support for STT tunneling.
155 - Support to configure method (--syslog-method argument) that determines
156 how daemons will talk with syslog.
157 - Support for "ovs-appctl vlog/list-pattern" command that lets to query
158 logging message format for each destination.
159 - GRE64 and ipsec_gre64 tunnel protocol is deprecated and will be removed
160 from OVS v2.5 release.
161 * The openvswitch-testcontroller package is new. It reintroduces the
162 simple OpenFlow controller that was packaged with Open vSwitch prior to
163 version 2.1, at request of users who find it useful for testing basic
164 OpenFlow setups. It is still not a necessary or desirable part of most
165 Open vSwitch deployments.

172 - OpenFlow 1.1, 1.2, and 1.3 are now enabled by default in
174 - Linux kernel datapath now has an exact match cache optimizing the
175 flow matching process.
176 - Datapath flows now have partially wildcarded tranport port field
177 matches. This reduces userspace upcalls, but increases the
178 number of different masks in the datapath. The kernel datapath
179 exact match cache removes the overhead of matching the incoming
180 packets with the larger number of masks, but when paired with an
181 older kernel module, some workloads may perform worse with the

188 * New upstream version
189 - Internal ports are no longer brought up by default, because it
190 should be an administrator task to bring up devices as they are
192 - ovs-vsctl now reports when ovs-vswitchd fails to create a new port or
194 - The "ovsdbmonitor" graphical tool has been removed, because it was
195 poorly maintained and not widely used.
196 - New "check-ryu" Makefile target for running Ryu tests for OpenFlow
197 controllers against Open vSwitch. See INSTALL for details.
198 - Added IPFIX support for SCTP flows and templates for ICMPv4/v6 flows.
199 - Upon the receipt of a SIGHUP signal, ovs-vswitchd no longer reopens its
200 log file (it will terminate instead). Please use 'ovs-appctl vlog/reopen'
202 - Support for Linux kernels up to 3.14. From Kernel 3.12 onwards OVS uses
203 tunnel API for GRE and VXLAN.
204 - Added DPDK support.
205 - Added support for custom vlog patterns in Python

209 openvswitch (2.1.0-1) unstable; urgency=low
210 [ Open vSwitch team ]
211 * New upstream version
212 - Address prefix tracking support for flow tables. New columns
213 "prefixes" in OVS-DB table "Flow_Table" controls which packet
214 header fields are used for address prefix tracking. Prefix
215 tracking allows the classifier to skip rules with longer than
216 necessary prefixes, resulting in better wildcarding for datapath
217 flows. Default configuration is to not use any fields for prefix
218 tracking. However, if any flow tables contain both exact matches
219 and masked matches for IP address fields, OVS performance may be
220 increased by using this feature.
221 * As of now, the fields for which prefix lookup can be enabled
222 are: 'tun_id', 'tun_src', 'tun_dst', 'nw_src', 'nw_dst' (or
223 aliases 'ip_src' and 'ip_dst'), 'ipv6_src', and 'ipv6_dst'.
224 (Using this feature for 'tun_id' would only make sense if the
225 tunnel IDs have prefix structure similar to IP addresses.)
226 * There is a maximum number of fields that can be enabled for any
227 one flow table. Currently this limit is 3.
229 $ ovs-vsctl set Bridge br0 flow_tables:0=@N1 -- \
230 --id=@N1 create Flow_Table name=table0
231 $ ovs-vsctl set Bridge br0 flow_tables:1=@N1 -- \
232 --id=@N1 create Flow_Table name=table1
233 $ ovs-vsctl set Flow_Table table0 prefixes=ip_dst,ip_src
234 $ ovs-vsctl set Flow_Table table1 prefixes=[]
235 - TCP flags matching: OVS now supports matching of TCP flags. This
236 has an adverse performance impact when using OVS userspace 1.10
237 or older (no megaflows support) together with the new OVS kernel
238 module. It is recommended that the kernel and userspace modules
239 both are upgraded at the same time.
240 - The default OpenFlow and OVSDB ports will change to
241 IANA-assigned numbers in a future release. Consider updating
242 your installations to specify port numbers instead of using the
245 * The OpenFlow 1.1+ "Write-Actions" instruction is now supported.
246 * OVS limits the OpenFlow port numbers it assigns to port 32767 and
247 below, leaving port numbers above that range free for assignment
249 * ovs-vswitchd now honors changes to the "ofport_request" column
250 in the Interface table by changing the port's OpenFlow port
252 - ovs-vswitchd.conf.db.5 man page will contain graphviz/dot
253 diagram only if graphviz package was installed at the build time.
254 - Support for Linux kernels up to 3.11
256 The "show" command also displays mega flow mask stats.
258 * New command "ofp-parse-pcap" to dump OpenFlow from PCAP files.
259 - ovs-controller has been renamed test-controller. It is no longer
260 packaged or installed by default, because too many users assumed
261 incorrectly that ovs-controller was a necessary or desirable part
262 of an Open vSwitch deployment.
263 - Added vlog option to export to a UDP syslog sink.
265 * The "monitor" command can now monitor all tables in a database,
266 instead of being limited to a single table.
267 - The flow-eviction-threshold has been replaced by the flow-limit which is a
268 hard limit on the number of flows in the datapath. It defaults to 200,000
269 flows. OVS automatically adjusts this number depending on network
271 * The openvswitch-controller package has been removed, because too many
272 users assumed incorrectly that ovs-controller was a necessary or
273 desirable part of an Open vSwitch deployment.

281 threads are now used to handle flow set up and asynchronous
284 * Experimental support for OpenFlow 1.1 (in addition to 1.2 and
285 1.3, which had experimental support in 1.10).
286 * New support for matching outer source and destination IP address
287 of tunneled packets, for tunnel ports configured with the newly

296 vSwitch. See README-OFTest for details.
297 - The flow eviction threshold has been moved to the Open_vSwitch table.
298 - Database names are now mandatory when specifying ovsdb-server options
299 through database paths (e.g. Private key option with the database name
300 should look like "--private-key=db:Open_vSwitch,SSL,private_key").
301 - Added ovs-dev.py, a utility script helpful for Open vSwitch developers.
302 - Support for Linux kernels up to 3.10
304 * New "ofp-parse" for printing OpenFlow messages read from a file.
305 - Added configurable flow caching support to IPFIX exporter.

317 any dpif implementation that supports wildcards). Depending on
318 the flow table and switch configuration, flow set up rates are
319 close to the Linux bridge.
320 - The "tutorial" directory contains a new tutorial for some advanced
321 Open vSwitch features.
322 - Stable bond mode has been removed.
323 - The autopath action has been removed.
324 - New support for the data encapsulation format of the LISP tunnel
325 protocol (RFC 6830). An external control plane or manual flow
326 setup is required for EID-to-RLOC mapping.
328 * The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow
329 1.1 and later are now implemented.
330 * New "stack" extension for use in actions, to push and pop from
332 * The "load" and "set_field" actions can now modify the "in_port". (This
333 allows one to enable output to a flow's input port by setting the
334 in_port to some unused value, such as OFPP_NONE.)
336 * New debugging commands "add-flow", "mod-flow", "del-flow".
337 - In dpif-based bridges, cache action translations, which can improve
338 flow set up performance by 80% with a complicated flow table.
339 - New syslog format, prefixed with "ovs|", to be easier to filter.
340 - RHEL: Removes the default firewall rule that allowed GRE traffic to
341 pass through. Any users that relied on this automatic firewall hole
342 will have to manually configure it. The ovs-ctl(8) manpage documents
343 the "enable-protocol" command that can be used as an alternative.

356 - The maximum size of the MAC learning table is now configurable.
357 - With the Linux datapath, packets for new flows are now queued
358 separately on a per-port basis, so it should no longer be
359 possible for a large number of new flows arriving on one port to
360 prevent new flows from being processed on other ports.
361 - Many "ovs-vsctl" database commands now accept an --if-exists option.
362 Please refer to the ovs-vsctl manpage for details.
364 - Experimental support for newer versions of OpenFlow. See
365 the "What versions of OpenFlow does Open vSwitch support?"
366 question in the FAQ for more details.
367 - The OpenFlow "dp_desc" may now be configured by setting the
368 value of other-config:dp-desc in the Bridge table.
369 - It is possible to request the OpenFlow port number with the
370 "ofport_request" column in the Interface table.
372 - New support for the VXLAN tunnel protocol (see the IETF draft here:
373 http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03).
374 - Tunneling requires the version of the kernel module paired with
375 Open vSwitch 1.9.0 or later.
376 - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit)
377 is no longer supported.
378 - Path MTU discovery is no longer supported.
380 - The "dump-flows" and "del-flows" no longer require an argument
381 if only one datapath exists.
383 - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit"
384 commands available allow control over logging rate limits.
385 - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command
386 that mimic the equivalent ovs-dpctl commands.
387 - The ofproto library is now responsible for assigning OpenFlow port
388 numbers. An ofproto implementation should assign them when
389 port_construct() is called.
390 - All dpif-based bridges of a particular type share a common
391 datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl
392 commands will now return information on that shared datapath. To
393 get the equivalent bridge-specific information, use the new
394 "ovs-appctl dpif/*" commands.
395 - Backward-incompatible changes:
396 - Earlier Open vSwitch versions treated ANY as a wildcard in flow
397 syntax. OpenFlow 1.1 adds a port named ANY, which introduces a
398 conflict. ANY was rarely used in flow syntax, so we chose to
399 retire that meaning of ANY in favor of the OpenFlow 1.1 meaning.
400 - Patch ports no longer require kernel support, so they now work
401 with FreeBSD and the kernel module built into Linux 3.3 and later.

413 Gaetano Catalli, Ed Maste, and Giuseppe Lettieri.
414 - ovs-bugtool: New --ovs option to report only OVS related information.

420 fields in IPv6 neighbor discovery messages, and IPv6 flow label.
421 - Adds support for writing to the metadata field for a flow.
423 - The tunneling code no longer assumes input and output keys are

425 tunneling to work. Note this only applies to flow-based keys.
426 - New support for a nonstandard form of GRE that supports a 64-bit key.
427 - Tunnel Path MTU Discovery default value was set to 'disabled'.
428 This feature is deprecated and will be removed soon.
429 - Tunnel header caching removed.
431 - Commands and actions that accept port numbers now also accept keywords
432 that represent those ports (such as LOCAL, NONE, and ALL). This is
433 also the recommended way to specify these ports, for compatibility
434 with OpenFlow 1.1 and later (which use the OpenFlow 1.0 numbers
435 for these ports for different purposes).
437 - Support requesting the port number with the "port_no" option in
438 the "add-if" command.
439 - ovs-pki: The "online PKI" features have been removed, along with
440 the ovs-pki-cgi program that facilitated it, because of some
441 alarmist insecurity claims. We do not believe that these claims
442 are true, but because we do not know of any users for this
443 feature it seems better on balance to remove it. (The ovs-pki-cgi
444 program was not included in distribution packaging.)

481 the multicast bit in the destination address could be individually
483 - New field OXM_OF_METADATA, to align with OpenFlow 1.1.
484 - The OFPST_QUEUE request now reports an error if a specified port or
485 queue does not exist, or for requests for a specific queue on all

505 - Increased the number of NXM registers to 8.
506 - Added ability to configure dscp setting for manager and controller
507 connections. By default, these connections have a DSCP value of
508 Internetwork Control (0xc0).

538 * New upstream version
540 - LACP bonds no longer fall back to balance-slb when negotiations fail.
541 Instead they drop traffic.
542 - The default bond_mode changed from SLB to active-backup, to protect
543 unsuspecting users from the significant risks of SLB bonds (which are
544 documented in vswitchd/INTERNALS).
545 - Load balancing can be disabled by setting the bond-rebalance-interval
548 - Added support for bitwise matching on TCP and UDP ports.
549 See ovs-ofctl(8) for more information.
550 - NXM flow dumps now include times elapsed toward idle and hard
552 - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows
553 controllers more precise control over which OpenFlow messages they
554 receive asynchronously.
555 - New "fin_timeout" action.
556 - Added "fin_timeout" support to "learn" action.
557 - The default MAC learning timeout has been increased from 60 seconds
558 to 300 seconds. The MAC learning timeout is now configurable.
559 - When QoS settings for an interface do not configure a default queue
560 (queue 0), Open vSwitch now uses a default configuration for that
561 queue, instead of dropping all packets as in previous versions.
562 - Logging to console and file will have UTC timestamp as a default for all
563 the daemons. An example of the default format is 2012-01-27T16:35:17Z.
564 ovs-appctl can be used to change the default format as before.
565 - New support for limiting the number of flows in an OpenFlow flow
566 table, with configurable policy for evicting flows upon
567 overflow. See the Flow_Table table in ovs-vswitch.conf.db(5)
568 for more information.
569 - New "enable-async-messages" column in the Controller table. If set to
570 false, OpenFlow connections to the controller will initially have all
571 asynchronous messages disabled, overriding normal OpenFlow behavior.
572 - ofproto-provider interface:
573 - "struct rule" has a new member "used" that ofproto implementations
574 should maintain by updating with ofproto_rule_update_used().
576 - The new option --timestamp causes the "monitor" command to print
577 a timestamp with every update.
578 - CFM module CCM broadcasts can now be tagged with an 802.1p priority.

745 of just one. By default, only table 0 is consulted, but the
746 new NXAST_RESUBMIT_TABLE action can look up in additional
747 tables. Tables 128 and above are reserved for use by the
