1 | post-v1.10.0 |
2 | --------------------- | |
df53d41c | 3 | - Stable bond mode has been removed. |
1bda9b9e | 4 | - The autopath action has been removed. |
a6ae068b LJ |
5 | - New support for the data encapsulation format of the LISP tunnel |
6 | protocol (RFC 6830). An external control plane or manual flow | |
7 | setup is required for EID-to-RLOC mapping. | |
b676167a | 8 | - OpenFlow: |
0f3f3c3d SH |
9 | * The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow |
10 | 1.1 and later are now implemented. | |
bd85dac1 AZ |
11 | * New "stack" extension for use in actions, to push and pop from |
12 | NXM fields. | |
186afbfe BP |
13 | - ovs-dpctl: |
14 | * New debugging commands "add-flow", "mod-flow", "del-flow". | |

17 | v1.10.0 - xx xxx xxxx |
18 | --------------------- | |
685e46da BP |
19 | - Bridge compatibility support has been removed. Any uses that |
20 | rely on ovs-brcompatd will have to stick with Open vSwitch 1.9.x | |
21 | or adapt to native Open vSwitch support (e.g. use ovs-vsctl instead | |
22 | of brctl). | |
c4069512 | 23 | - The maximum size of the MAC learning table is now configurable. |
989fd548 JP |
24 | - With the Linux datapath, packets for new flows are now queued |
25 | separately on a per-port basis, so it should no longer be | |
26 | possible for a large number of new flows arriving on one port to | |
27 | prevent new flows from being processed on other ports. | |
43d18dc1 BP |
28 | - ovs-vsctl: |
29 | * Previously ovs-vsctl would retry connecting to the database forever, | |
30 | causing it to hang if ovsdb-server was not running. Now, ovs-vsctl | |
31 | only tries once by default (use --retry to try forever). This change | |
32 | means that you may want to remove uses of --timeout to avoid hangs | |
33 | in ovs-vsctl calls. | |
34 | * Many "ovs-vsctl" database commands now accept an --if-exists option. | |
35 | Please refer to the ovs-vsctl manpage for details. | |
e6024057 | 36 | - OpenFlow: |
d6123831 JP |
37 | - Experimental support for newer versions of OpenFlow. See |
38 | the "What versions of OpenFlow does Open vSwitch support?" | |
39 | question in the FAQ for more details. | |
e6024057 JP |
40 | - The OpenFlow "dp_desc" may now be configured by setting the |
41 | value of other-config:dp-desc in the Bridge table. | |
42 | - It is possible to request the OpenFlow port number with the | |
43 | "ofport_request" column in the Interface table. | |
c9accf5b BP |
44 | - The NXM flow_removed message now reports the OpenFlow table ID |
45 | from which the flow was removed. | |
3c23e920 JP |
46 | - Tunneling: |
47 | - New support for the VXLAN tunnel protocol (see the IETF draft here: | |
238bc978 | 48 | http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03). |
3c23e920 JP |
49 | - Tunneling requires the version of the kernel module paired with |
50 | Open vSwitch 1.9.0 or later. | |
51 | - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit) | |
52 | is no longer supported. | |
53 | - Path MTU discovery is no longer supported. | |
ccd989e0 JG |
54 | - CAPWAP tunneling support removed. |
55 | - Tunnels with multicast destination ports are no longer supported. | |
e6024057 JP |
56 | - ovs-dpctl: |
57 | - The "dump-flows" and "del-flows" no longer require an argument | |
58 | if only one datapath exists. | |
59 | - ovs-appctl: | |
60 | - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit" | |
61 | commands available allow control over logging rate limits. | |
62 | - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command | |
63 | that mimic the equivalent ovs-dpctl commands. | |
e6024057 JP |
64 | - The ofproto library is now responsible for assigning OpenFlow port |
65 | numbers. An ofproto implementation should assign them when | |
66 | port_construct() is called. | |
67 | - All dpif-based bridges of a particular type share a common | |
68 | datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl | |
69 | commands will now return information on that shared datapath. To | |
70 | get the equivalent bridge-specific information, use the new | |
71 | "ovs-appctl dpif/*" commands. | |
bedde04c GS |
72 | - Backward-incompatible changes: |
73 | - Earlier Open vSwitch versions treated ANY as a wildcard in flow | |
74 | syntax. OpenFlow 1.1 adds a port named ANY, which introduces a | |
75 | conflict. ANY was rarely used in flow syntax, so we chose to | |
76 | retire that meaning of ANY in favor of the OpenFlow 1.1 meaning. | |
3c23e920 JP |
77 | - Patch ports no longer require kernel support, so they now work |
78 | with FreeBSD and the kernel module built into Linux 3.3 and later. | |
f07ee64c | 79 | |
e5f77cc3 | 80 | |
fdfe872d JP |
81 | v1.9.0 - 26 Feb 2013 |
82 | ------------------------ | |
72e8bf28 AA |
83 | - Datapath: |
84 | - Support for ipv6 set action. | |
85 | - SKB mark matching and setting. | |
64807dfb | 86 | - support for Linux kernels up to 3.8 |
f6eb6b20 GL |
87 | - FreeBSD is now a supported platform, thanks to code contributions from |
88 | Gaetano Catalli, Ed Maste, and Giuseppe Lettieri. | |
b592e726 | 89 | - ovs-bugtool: New --ovs option to report only OVS related information. |
781dee08 BP |
90 | - New %t and %T log escapes to identify the subprogram within a |
91 | cooperating group of processes or threads that emitted a log message. | |
92 | The default log patterns now include this information. | |
32455024 | 93 | - OpenFlow: |
e878338b SH |
94 | - Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL |
95 | fields in IPv6 neighbor discovery messages, and IPv6 flow label. | |
4cceacb9 | 96 | - Adds support for writing to the metadata field for a flow. |
3c23e920 JP |
97 | - Tunneling: |
98 | - The tunneling code no longer assumes input and output keys are | |
99 | symmetric. If they are not, PMTUD needs to be disabled for | |
100 | tunneling to work. Note this only applies to flow-based keys. | |
101 | - New support for a nonstandard form of GRE that supports a 64-bit key. | |
102 | - Tunnel Path MTU Discovery default value was set to 'disabled'. | |
103 | This feature is deprecated and will be removed soon. | |
104 | - Tunnel header caching removed. | |
c6100d92 BP |
105 | - ovs-ofctl: |
106 | - Commands and actions that accept port numbers now also accept keywords | |
107 | that represent those ports (such as LOCAL, NONE, and ALL). This is | |
108 | also the recommended way to specify these ports, for compatibility | |
109 | with OpenFlow 1.1 and later (which use the OpenFlow 1.0 numbers | |
110 | for these ports for different purposes). | |
2562714a | 111 | - ovs-dpctl: |
4b3b8d8f JP |
112 | - Support requesting the port number with the "port_no" option in |
113 | the "add-if" command. | |
2562714a BP |
114 | - ovs-pki: The "online PKI" features have been removed, along with |
115 | the ovs-pki-cgi program that facilitated it, because of some | |
116 | alarmist insecurity claims. We do not believe that these claims | |
117 | are true, but because we do not know of any users for this | |
118 | feature it seems better on balance to remove it. (The ovs-pki-cgi | |
119 | program was not included in distribution packaging.) | |
341c4e59 BP |
120 | - ovsdb-server now enforces the immutability of immutable columns. This |
121 | was not enforced in earlier versions due to an oversight. | |
fd38af85 BP |
122 | - The following features are now deprecated. They will be removed no |
123 | earlier than February 2013. Please email dev@openvswitch.org with | |
124 | concerns. | |
a8643e44 | 125 | - Bridge compatibility. |
fd38af85 BP |
126 | - Stable bond mode. |
127 | - The autopath action. | |
128 | - Interface type "null". | |
129 | - Numeric values for reserved ports (see "ovs-ofctl" note above). | |
85340733 | 130 | - Tunnel Path MTU Discovery. |
1280bf0e | 131 | - CAPWAP tunnel support. |
f07ee64c MM |
132 | - The data in the RARP packets can now be matched in the same way as the |
133 | data in ARP packets. | |
945cad7f | 134 | |
79f827fa | 135 | |
fdfe872d | 136 | v1.8.0 - 26 Feb 2013 |
c8d5d22c | 137 | ------------------------ |

c483d489 | 139 | - New FAQ. Please send updates and additions! |
f25d0cf3 BP |
140 | - Authors of controllers, please read the new section titled "Action |
141 | Reproduction" in DESIGN, which describes an Open vSwitch change in | |
142 | behavior in corner cases that may affect some controllers. | |
2d8bdd8f AA |
143 | - ovs-l3ping: |
144 | - A new test utility that can create L3 tunnel between two Open | |
145 | vSwitches and detect connectivity issues. | |
5498c01f | 146 | - ovs-ofctl: |
bdcc5925 | 147 | - New --sort and --rsort options for "dump-flows" command. |

c08201d6 | 149 | - OpenFlow: |
ff0b06ee BP |
150 | - Allow general bitwise masking for IPv4 and IPv6 addresses in |
151 | IPv4, IPv6, and ARP packets. (Previously, only CIDR masks | |
c08201d6 BP |
152 | were allowed.) |
153 | - Allow support for arbitrary Ethernet masks. (Previously, only | |
154 | the multicast bit in the destination address could be individually | |
155 | masked.) | |
969fc56c | 156 | - New field OXM_OF_METADATA, to align with OpenFlow 1.1. |
0414d158 BP |
157 | - The OFPST_QUEUE request now reports an error if a specified port or |
158 | queue does not exist, or for requests for a specific queue on all | |
159 | ports, if the specified queue does not exist on any port. (Previous | |
160 | versions generally reported an empty set of results.) | |
2b07c8b1 BP |
161 | - New "flow monitor" feature to allow controllers to be notified of |
162 | flow table changes as they happen. | |
c93f9a78 EJ |

164 | false. For a full list, see the ovs-vswitchd.conf.db man page. | |
38f7147c EJ |
165 | - Open vSwitch now sends RARP packets in situations where it previously |
166 | sent a custom protocol, making it consistent with behavior of QEMU and | |
167 | VMware. | |
969e46a2 AS |
168 | - All Open vSwitch programs and log files now show timestamps in UTC, |
169 | instead the local timezone, by default. | |
c8d5d22c JP |

3b4ab170 | 172 | v1.7.0 - 30 Jul 2012 |
dd1ba5b3 | 173 | ------------------------ |
9b80f761 CW |
174 | - kernel modules are renamed. openvswitch_mod.ko is now |
175 | openvswitch.ko and brcompat_mod.ko is now brcompat.ko. | |

179 | Internetwork Control (0xc0). | |
3967a833 MM |
180 | - Added the granular link health statistics, 'cfm_health', to an |
181 | interface. | |
47284b1f AA |
182 | - OpenFlow: |
183 | - Added support to mask nd_target for ICMPv6 neighbor discovery flows. | |

185 | multipart messages. | |
186 | - ovs-ofctl: | |
187 | - Added the "dump-ports-desc" command to retrieve port | |
188 | information using the new port description multipart messages. | |
8d25d9a2 AA |
189 | - ovs-test: |
190 | - Added support for spawning ovs-test server from the client. | |
191 | - Now ovs-test is able to automatically create test bridges and ports. | |
7393104d | 192 | - "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows. |
22dd5cec | 193 | - Tripled flow setup performance. |
a5f607bc BP |
194 | - The "coverage/log" command previously available through ovs-appctl |
195 | has been replaced by "coverage/show". The new command replies with | |
196 | coverage counter values, instead of logging them. | |
dd1ba5b3 JP |

202 | ||
203 | ||
204 | v1.6.0 - 24 Feb 2012 | |
205 | ------------------------ | |
206 | *** Internal only release *** | |
4df08875 | 207 | - bonding |
bdebeece EJ |
208 | - LACP bonds no longer fall back to balance-slb when negotiations fail. |
209 | Instead they drop traffic. | |
4df08875 EJ |
210 | - The default bond_mode changed from SLB to active-backup, to protect |
211 | unsuspecting users from the significant risks of SLB bonds (which are | |
212 | documented in vswitchd/INTERNALS). | |
bc1b010c EJ |
213 | - Load balancing can be disabled by setting the bond-rebalance-interval |
214 | to zero. | |
73f33563 BP |
215 | - OpenFlow: |
216 | - Added support for bitwise matching on TCP and UDP ports. | |
217 | See ovs-ofctl(8) for more information. | |
80d5aefd BP |
218 | - NXM flow dumps now include times elapsed toward idle and hard |
219 | timeouts. | |
220 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |
221 | controllers more precise control over which OpenFlow messages they | |
222 | receive asynchronously. | |
0e553d9c BP |
223 | - New "fin_timeout" action. |
224 | - Added "fin_timeout" support to "learn" action. | |
a7349929 BP |
225 | - New Nicira action NXAST_CONTROLLER that offers additional features |
226 | over output to OFPP_CONTROLLER. | |
2c999774 BP |
227 | - When QoS settings for an interface do not configure a default queue |
228 | (queue 0), Open vSwitch now uses a default configuration for that | |
229 | queue, instead of dropping all packets as in previous versions. | |
2a3e30b2 BP |
230 | - Logging: |
231 | - Logging to console and file will have UTC timestamp as a default for | |
232 | all the daemons. An example of the default format is | |
233 | 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default | |
234 | format as before. | |
235 | - The syntax of commands and options to set log levels was simplified, | |
236 | to make it easier to remember. | |
254750ce BP |
237 | - New support for limiting the number of flows in an OpenFlow flow |
238 | table, with configurable policy for evicting flows upon | |
239 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
240 | for more information. | |
9886b662 BP |
241 | - New "enable-async-messages" column in the Controller table. If set to |
242 | false, OpenFlow connections to the controller will initially have all | |
243 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
1745cd08 BP |
244 | - ofproto-provider interface: |
245 | - "struct rule" has a new member "used" that ofproto implementations | |
246 | should maintain by updating with ofproto_rule_update_used(). | |
8f46c9bb BP |
247 | - ovsdb-client: |
248 | - The new option --timestamp causes the "monitor" command to print | |
249 | a timestamp with every update. | |
a7aa2d3c | 250 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. |
d0a8c2e0 JP |

e729e793 JP |
255 | - OpenFlow: |
256 | - Added support for querying, modifying, and deleting flows | |
257 | based on flow cookie when using NXM. | |
b4b7f827 | 258 | - Added new NXM_PACKET_IN format. |
f0fd1a17 | 259 | - Added new NXAST_DEC_TTL action. |
1eb85ef5 EJ |
260 | - ovs-ofctl: |
261 | - Added daemonization support to the monitor and snoop commands. | |

266 | directories as defaults. | |
d1add61d JP |
267 | - The default MAC learning timeout has been increased from 60 seconds |
268 | to 300 seconds. The MAC learning timeout is now configurable. | |
e68bfcfc JP |

ef13dc11 | 271 | v1.4.0 - 30 Jan 2012 |
b6a9a95b | 272 | ------------------------ |
50bf17cd | 273 | - Compatible with Open vSwitch kernel module included in Linux 3.3. |
52a90c29 BP |
274 | - New "VLAN splinters" feature to work around buggy device drivers |
275 | in old Linux versions. (This feature is deprecated. When | |
276 | broken device drivers are no longer in widespread use, we will | |
277 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
278 | information. | |
fa8223b7 JP |
279 | - OpenFlow: |
280 | - Added ability to match on IPv6 flow label through NXM. | |
530180fd | 281 | - Added ability to match on ECN bits in IPv4 and IPv6 through NXM. |
a61680c6 | 282 | - Added ability to match on TTL in IPv4 and IPv6 through NXM. |
530180fd | 283 | - Added ability to modify ECN bits in IPv4. |
a61680c6 | 284 | - Added ability to modify TTL in IPv4. |
9d24de3b | 285 | - ovs-vswitchd: |
c06bba01 JP |
286 | - Don't require the "normal" action to use mirrors. Traffic will |
287 | now be properly mirrored for any flows, regardless of their | |
288 | actions. | |
9d24de3b | 289 | - Track packet and byte statistics sent on mirrors. |
733adf2a LG |
290 | - The sFlow implementation can now usually infer the correct agent |
291 | device instead of having to be told explicitly. | |
f0a3aa2e AA |
292 | - ovs-appctl: |
293 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
0be6140a AA |
294 | - ovs-test: |
295 | - A new distributed testing tool that allows one to diagnose performance | |
296 | and connectivity issues. This tool currently is not included in RH or | |
297 | Xen packages. | |
0fb42626 | 298 | - RHEL packaging now supports integration with Red Hat network scripts. |
4c57c3bc EJ |
299 | - bonding: |
300 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
301 | to active-backup. SLB bonds carry significant risks with them | |
302 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
303 | users from running into. Users are advised to update any scripts or | |
304 | configuration which may be negatively impacted by explicitly setting | |
305 | the bond mode which they want to use. | |
b6a9a95b | 306 | |
0be6140a | 307 | |
ddc29387 | 308 | v1.3.0 - 09 Dec 2011 |

310 | - OpenFlow: |
311 | - Added an OpenFlow extension which allows the "output" action to accept | |
312 | NXM fields. | |
75a75043 | 313 | - Added an OpenFlow extension for flexible learning. |
d2c0fed9 | 314 | - Bumped number of NXM registers from four to five. |
d5e1e5ed | 315 | - ovs-appctl: |
ae75dae3 JP |
316 | - New "version" command to determine version of running daemon. |
317 | - If no argument is provided for "cfm/show", displays detailed | |
318 | information about all interfaces with CFM enabled. | |
5dab8ece JP |
319 | - If no argument is provided for "lacp/show", displays detailed |
320 | information about all ports with LACP enabled. | |
10500639 BP |
321 | - ovs-dpctl: |
322 | - New "set-if" command to modify a datapath port's configuration. | |
29901626 BP |
323 | - ovs-vswitchd: |
324 | - The software switch now supports 255 OpenFlow tables, instead | |
325 | of just one. By default, only table 0 is consulted, but the | |
326 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
327 | tables. Tables 128 and above are reserved for use by the | |
328 | switch itself; please use only tables 0 through 127. | |
21f7563c | 329 | - Add support for 802.1D spanning tree (STP). |
7257b535 BP |
330 | - Fragment handling extensions: |
331 | - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4 | |
332 | fields are made available for matching in fragments with | |
333 | offset 0. | |
334 | - New NXM_NX_IP_FRAG match field for matching IP fragments (usable | |
335 | via "ip_frag" in ovs-ofctl). | |
336 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
337 | fragment handling policy. | |
2f4bc10d BP |
338 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. |
339 | By default it remains compatible with the old version and other | |
c87112ca | 340 | standards-based implementations. |
17411ecf JG |
341 | - Flow setups are now processed in a round-robin manner across ports |
342 | to prevent any single client from monopolizing the CPU and conducting | |
343 | a denial of service attack. | |

b78f6b77 | 350 | ------------------------ |
1a142ced JP |
351 | - New "ofproto" abstraction layer to ease porting to hardware |
352 | switching ASICs. | |

359 | - Support cooperative locking between callers. | |
360 | - ovs-dpctl: | |
361 | - New "-s" option for "show" command prints packet and byte | |
362 | counters for each port. | |
c4ea79bf BP |
363 | - ovs-ofctl: |
364 | - New "--readd" option for "replace-flows". | |
9b1735a7 BP |

045b2e5c BP |
369 | - ovs-openflowd has been renamed test-openflowd and moved into the |
370 | tests directory. Its presence confused too many users. Please | |
371 | use ovs-vswitchd instead. | |
1a142ced JP |
372 | - New ovs-benchmark utility to test flow setup performance. |
373 | - A new log level "off" has been added. Configuring a log facility | |
374 | "off" prevents any messages from being logged to it. Previously, | |
375 | "emer" was effectively "off" because no messages were ever logged at | |
376 | level "emer". Now, errors that cause a process to exit are logged | |
377 | at "emer" level. | |
8a2d6596 BP |
378 | - "configure" option --with-l26 has been renamed --with-linux, and |
379 | --with-l26-source has been renamed --with-linux-source. The old | |

440 | sending to an output port. | |
441 | - Open vSwitch now reports a single flow table, instead of | |
442 | separate hash and wildcard tables. This better models the | |
443 | current implementation. | |

445 | - New "ofproto/trace" ovs-appctl command and associated utilities | |
446 | to ease debugging complex flow tables. | |
