1 | post-v1.12.0 | |
2 | --------------------- | |
3 | - OpenFlow: | |
4 | * Support matching, rewriting SCTP ports | |
5 | ||
6 | ||
7 | v1.12.0 - xx xxx xxxx | |
8 | --------------------- | |
9 | - OpenFlow: | |
10 | * Experimental support for OpenFlow 1.1 (in addition to 1.2 and | |
11 | 1.3, which had experimental support in 1.10). | |
12 | * New support for matching outer source and destination IP address | |
13 | of tunneled packets, for tunnel ports configured with the newly | |
14 | added "remote_ip=flow" and "local_ip=flow" options. | |
15 | * Support for matching on metadata 'pkt_mark' for interacting with | |
16 | other system components. On Linux this corresponds to the skb | |
17 | mark. | |
18 | - The Interface table in the database has a new "ifindex" column to | |
19 | report the interface's OS-assigned ifindex. | |
20 | - New "check-oftest" Makefile target for running OFTest against Open | |
21 | vSwitch. See README-OFTest for details. | |
22 | - The flow eviction threshold has been moved to the Open_vSwitch table. | |
23 | - Database names are now mandatory when specifying ovsdb-server options | |
24 | through database paths (e.g. Private key option with the database name | |
25 | should look like "--private-key=db:Open_vSwitch,SSL,private_key"). | |
26 | - Added ovs-dev.py, a utility script helpful for Open vSwitch developers. | |
27 | - Support for Linux kernels up to 3.10 | |
28 | - ovs-ofctl: | |
29 | * New "ofp-parse" for printing OpenFlow messages read from a file. | |
30 | - Added configurable flow caching support to IPFIX exporter. | |
31 | ||
32 | ||
33 | v1.11.0 - xx xxx xxxx | |
34 | --------------------- | |
35 | - Support for megaflows, which allows wildcarding in the kernel (and | |
36 | any dpif implementation that supports wildcards). Depending on | |
37 | the flow table and switch configuration, flow set up rates are | |
38 | close to the Linux bridge. | |
39 | - The "tutorial" directory contains a new tutorial for some advanced | |
40 | Open vSwitch features. | |
41 | - Stable bond mode has been removed. | |
42 | - The autopath action has been removed. | |
43 | - New support for the data encapsulation format of the LISP tunnel | |
44 | protocol (RFC 6830). An external control plane or manual flow | |
45 | setup is required for EID-to-RLOC mapping. | |
46 | - OpenFlow: | |
47 | * The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow | |
48 | 1.1 and later are now implemented. | |
49 | * New "stack" extension for use in actions, to push and pop from | |
50 | NXM fields. | |
51 | * The "load" and "set_field" actions can now modify the "in_port". (This | |
52 | allows one to enable output to a flow's input port by setting the | |
53 | in_port to some unused value, such as OFPP_NONE.) | |
54 | - ovs-dpctl: | |
55 | * New debugging commands "add-flow", "mod-flow", "del-flow". | |
56 | * "dump-flows" now has a -m option to increase output verbosity. | |
57 | - In dpif-based bridges, cache action translations, which can improve | |
58 | flow set up performance by 80% with a complicated flow table. | |
59 | - New syslog format, prefixed with "ovs|", to be easier to filter. | |
60 | - RHEL: Removes the default firewall rule that allowed GRE traffic to | |
61 | pass through. Any users that relied on this automatic firewall hole | |
62 | will have to manually configure it. The ovs-ctl(8) manpage documents | |
63 | the "enable-protocol" command that can be used as an alternative. | |
64 | - New CFM demand mode which uses data traffic to indicate interface | |
65 | liveness. | |
66 | ||
67 | v1.10.0 - 01 May 2013 | |
68 | --------------------- | |
69 | - Bridge compatibility support has been removed. Any uses that | |
70 | rely on ovs-brcompatd will have to stick with Open vSwitch 1.9.x | |
71 | or adapt to native Open vSwitch support (e.g. use ovs-vsctl instead | |
72 | of brctl). | |
73 | - The maximum size of the MAC learning table is now configurable. | |
74 | - With the Linux datapath, packets for new flows are now queued | |
75 | separately on a per-port basis, so it should no longer be | |
76 | possible for a large number of new flows arriving on one port to | |
77 | prevent new flows from being processed on other ports. | |
78 | - ovs-vsctl: | |
79 | * Previously ovs-vsctl would retry connecting to the database forever, | |
80 | causing it to hang if ovsdb-server was not running. Now, ovs-vsctl | |
81 | only tries once by default (use --retry to try forever). This change | |
82 | means that you may want to remove uses of --timeout to avoid hangs | |
83 | in ovs-vsctl calls. | |
84 | * Many "ovs-vsctl" database commands now accept an --if-exists option. | |
85 | Please refer to the ovs-vsctl manpage for details. | |
86 | - OpenFlow: | |
87 | - Experimental support for newer versions of OpenFlow. See | |
88 | the "What versions of OpenFlow does Open vSwitch support?" | |
89 | question in the FAQ for more details. | |
90 | - The OpenFlow "dp_desc" may now be configured by setting the | |
91 | value of other-config:dp-desc in the Bridge table. | |
92 | - It is possible to request the OpenFlow port number with the | |
93 | "ofport_request" column in the Interface table. | |
94 | - The NXM flow_removed message now reports the OpenFlow table ID | |
95 | from which the flow was removed. | |
96 | - Tunneling: | |
97 | - New support for the VXLAN tunnel protocol (see the IETF draft here: | |
98 | http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03). | |
99 | - Tunneling requires the version of the kernel module paired with | |
100 | Open vSwitch 1.9.0 or later. | |
101 | - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit) | |
102 | is no longer supported. | |
103 | - Path MTU discovery is no longer supported. | |
104 | - CAPWAP tunneling support removed. | |
105 | - Tunnels with multicast destination ports are no longer supported. | |
106 | - ovs-dpctl: | |
107 | - The "dump-flows" and "del-flows" no longer require an argument | |
108 | if only one datapath exists. | |
109 | - ovs-appctl: | |
110 | - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit" | |
111 | commands available allow control over logging rate limits. | |
112 | - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command | |
113 | that mimic the equivalent ovs-dpctl commands. | |
114 | - The ofproto library is now responsible for assigning OpenFlow port | |
115 | numbers. An ofproto implementation should assign them when | |
116 | port_construct() is called. | |
117 | - All dpif-based bridges of a particular type share a common | |
118 | datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl | |
119 | commands will now return information on that shared datapath. To | |
120 | get the equivalent bridge-specific information, use the new | |
121 | "ovs-appctl dpif/*" commands. | |
122 | - Backward-incompatible changes: | |
123 | - Earlier Open vSwitch versions treated ANY as a wildcard in flow | |
124 | syntax. OpenFlow 1.1 adds a port named ANY, which introduces a | |
125 | conflict. ANY was rarely used in flow syntax, so we chose to | |
126 | retire that meaning of ANY in favor of the OpenFlow 1.1 meaning. | |
127 | - Patch ports no longer require kernel support, so they now work | |
128 | with FreeBSD and the kernel module built into Linux 3.3 and later. | |
129 | - New "sample" action. | |
130 | ||
131 | ||
132 | v1.9.0 - 26 Feb 2013 | |
133 | ------------------------ | |
134 | - Datapath: | |
135 | - Support for ipv6 set action. | |
136 | - SKB mark matching and setting. | |
137 | - support for Linux kernels up to 3.8 | |
138 | - FreeBSD is now a supported platform, thanks to code contributions from | |
139 | Gaetano Catalli, Ed Maste, and Giuseppe Lettieri. | |
140 | - ovs-bugtool: New --ovs option to report only OVS related information. | |
141 | - New %t and %T log escapes to identify the subprogram within a | |
142 | cooperating group of processes or threads that emitted a log message. | |
143 | The default log patterns now include this information. | |
144 | - OpenFlow: | |
145 | - Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL | |
146 | fields in IPv6 neighbor discovery messages, and IPv6 flow label. | |
147 | - Adds support for writing to the metadata field for a flow. | |
148 | - Tunneling: | |
149 | - The tunneling code no longer assumes input and output keys are | |
150 | symmetric. If they are not, PMTUD needs to be disabled for | |
151 | tunneling to work. Note this only applies to flow-based keys. | |
152 | - New support for a nonstandard form of GRE that supports a 64-bit key. | |
153 | - Tunnel Path MTU Discovery default value was set to 'disabled'. | |
154 | This feature is deprecated and will be removed soon. | |
155 | - Tunnel header caching removed. | |
156 | - ovs-ofctl: | |
157 | - Commands and actions that accept port numbers now also accept keywords | |
158 | that represent those ports (such as LOCAL, NONE, and ALL). This is | |
159 | also the recommended way to specify these ports, for compatibility | |
160 | with OpenFlow 1.1 and later (which use the OpenFlow 1.0 numbers | |
161 | for these ports for different purposes). | |
162 | - ovs-dpctl: | |
163 | - Support requesting the port number with the "port_no" option in | |
164 | the "add-if" command. | |
165 | - ovs-pki: The "online PKI" features have been removed, along with | |
166 | the ovs-pki-cgi program that facilitated it, because of some | |
167 | alarmist insecurity claims. We do not believe that these claims | |
168 | are true, but because we do not know of any users for this | |
169 | feature it seems better on balance to remove it. (The ovs-pki-cgi | |
170 | program was not included in distribution packaging.) | |
171 | - ovsdb-server now enforces the immutability of immutable columns. This | |
172 | was not enforced in earlier versions due to an oversight. | |
173 | - The following features are now deprecated. They will be removed no | |
174 | earlier than February 2013. Please email dev@openvswitch.org with | |
175 | concerns. | |
176 | - Bridge compatibility. | |
177 | - Stable bond mode. | |
178 | - The autopath action. | |
179 | - Interface type "null". | |
180 | - Numeric values for reserved ports (see "ovs-ofctl" note above). | |
181 | - Tunnel Path MTU Discovery. | |
182 | - CAPWAP tunnel support. | |
183 | - The data in the RARP packets can now be matched in the same way as the | |
184 | data in ARP packets. | |
185 | ||
186 | ||
187 | v1.8.0 - 26 Feb 2013 | |
188 | ------------------------ | |
189 | *** Internal only release *** | |
190 | - New FAQ. Please send updates and additions! | |
191 | - Authors of controllers, please read the new section titled "Action | |
192 | Reproduction" in DESIGN, which describes an Open vSwitch change in | |
193 | behavior in corner cases that may affect some controllers. | |
194 | - ovs-l3ping: | |
195 | - A new test utility that can create L3 tunnel between two Open | |
196 | vSwitches and detect connectivity issues. | |
197 | - ovs-ofctl: | |
198 | - New --sort and --rsort options for "dump-flows" command. | |
199 | - "mod-port" command can now control all OpenFlow config flags. | |
200 | - OpenFlow: | |
201 | - Allow general bitwise masking for IPv4 and IPv6 addresses in | |
202 | IPv4, IPv6, and ARP packets. (Previously, only CIDR masks | |
203 | were allowed.) | |
204 | - Allow support for arbitrary Ethernet masks. (Previously, only | |
205 | the multicast bit in the destination address could be individually | |
206 | masked.) | |
207 | - New field OXM_OF_METADATA, to align with OpenFlow 1.1. | |
208 | - The OFPST_QUEUE request now reports an error if a specified port or | |
209 | queue does not exist, or for requests for a specific queue on all | |
210 | ports, if the specified queue does not exist on any port. (Previous | |
211 | versions generally reported an empty set of results.) | |
212 | - New "flow monitor" feature to allow controllers to be notified of | |
213 | flow table changes as they happen. | |
214 | - Additional protocols are not mirrored and dropped when forward-bpdu is | |
215 | false. For a full list, see the ovs-vswitchd.conf.db man page. | |
216 | - Open vSwitch now sends RARP packets in situations where it previously | |
217 | sent a custom protocol, making it consistent with behavior of QEMU and | |
218 | VMware. | |
219 | - All Open vSwitch programs and log files now show timestamps in UTC, | |
220 | instead the local timezone, by default. | |
221 | ||
222 | ||
223 | v1.7.0 - 30 Jul 2012 | |
224 | ------------------------ | |
225 | - kernel modules are renamed. openvswitch_mod.ko is now | |
226 | openvswitch.ko and brcompat_mod.ko is now brcompat.ko. | |
227 | - Increased the number of NXM registers to 8. | |
228 | - Added ability to configure DSCP setting for manager and controller | |
229 | connections. By default, these connections have a DSCP value of | |
230 | Internetwork Control (0xc0). | |
231 | - Added the granular link health statistics, 'cfm_health', to an | |
232 | interface. | |
233 | - OpenFlow: | |
234 | - Added support to mask nd_target for ICMPv6 neighbor discovery flows. | |
235 | - Added support for OpenFlow 1.3 port description (OFPMP_PORT_DESC) | |
236 | multipart messages. | |
237 | - ovs-ofctl: | |
238 | - Added the "dump-ports-desc" command to retrieve port | |
239 | information using the new port description multipart messages. | |
240 | - ovs-test: | |
241 | - Added support for spawning ovs-test server from the client. | |
242 | - Now ovs-test is able to automatically create test bridges and ports. | |
243 | - "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows. | |
244 | - Tripled flow setup performance. | |
245 | - The "coverage/log" command previously available through ovs-appctl | |
246 | has been replaced by "coverage/show". The new command replies with | |
247 | coverage counter values, instead of logging them. | |
248 | ||
249 | ||
250 | v1.6.1 - 25 Jun 2012 | |
251 | ------------------------ | |
252 | - Allow OFPP_CONTROLLER as the in_port for packet-out messages. | |
253 | ||
254 | ||
255 | v1.6.0 - 24 Feb 2012 | |
256 | ------------------------ | |
257 | *** Internal only release *** | |
258 | - bonding | |
259 | - LACP bonds no longer fall back to balance-slb when negotiations fail. | |
260 | Instead they drop traffic. | |
261 | - The default bond_mode changed from SLB to active-backup, to protect | |
262 | unsuspecting users from the significant risks of SLB bonds (which are | |
263 | documented in vswitchd/INTERNALS). | |
264 | - Load balancing can be disabled by setting the bond-rebalance-interval | |
265 | to zero. | |
266 | - OpenFlow: | |
267 | - Added support for bitwise matching on TCP and UDP ports. | |
268 | See ovs-ofctl(8) for more information. | |
269 | - NXM flow dumps now include times elapsed toward idle and hard | |
270 | timeouts. | |
271 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |
272 | controllers more precise control over which OpenFlow messages they | |
273 | receive asynchronously. | |
274 | - New "fin_timeout" action. | |
275 | - Added "fin_timeout" support to "learn" action. | |
276 | - New Nicira action NXAST_CONTROLLER that offers additional features | |
277 | over output to OFPP_CONTROLLER. | |
278 | - When QoS settings for an interface do not configure a default queue | |
279 | (queue 0), Open vSwitch now uses a default configuration for that | |
280 | queue, instead of dropping all packets as in previous versions. | |
281 | - Logging: | |
282 | - Logging to console and file will have UTC timestamp as a default for | |
283 | all the daemons. An example of the default format is | |
284 | 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default | |
285 | format as before. | |
286 | - The syntax of commands and options to set log levels was simplified, | |
287 | to make it easier to remember. | |
288 | - New support for limiting the number of flows in an OpenFlow flow | |
289 | table, with configurable policy for evicting flows upon | |
290 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
291 | for more information. | |
292 | - New "enable-async-messages" column in the Controller table. If set to | |
293 | false, OpenFlow connections to the controller will initially have all | |
294 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
295 | - ofproto-provider interface: | |
296 | - "struct rule" has a new member "used" that ofproto implementations | |
297 | should maintain by updating with ofproto_rule_update_used(). | |
298 | - ovsdb-client: | |
299 | - The new option --timestamp causes the "monitor" command to print | |
300 | a timestamp with every update. | |
301 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. | |
302 | ||
303 | ||
304 | v1.5.0 - 01 Jun 2012 | |
305 | ------------------------ | |
306 | - OpenFlow: | |
307 | - Added support for querying, modifying, and deleting flows | |
308 | based on flow cookie when using NXM. | |
309 | - Added new NXM_PACKET_IN format. | |
310 | - Added new NXAST_DEC_TTL action. | |
311 | - ovs-ofctl: | |
312 | - Added daemonization support to the monitor and snoop commands. | |
313 | - ovs-vsctl: | |
314 | - The "find" command supports new set relational operators | |
315 | {=}, {!=}, {<}, {>}, {<=}, and {>=}. | |
316 | - ovsdb-tool now uses the typical database and schema installation | |
317 | directories as defaults. | |
318 | - The default MAC learning timeout has been increased from 60 seconds | |
319 | to 300 seconds. The MAC learning timeout is now configurable. | |
320 | ||
321 | ||
322 | v1.4.0 - 30 Jan 2012 | |
323 | ------------------------ | |
324 | - Compatible with Open vSwitch kernel module included in Linux 3.3. | |
325 | - New "VLAN splinters" feature to work around buggy device drivers | |
326 | in old Linux versions. (This feature is deprecated. When | |
327 | broken device drivers are no longer in widespread use, we will | |
328 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
329 | information. | |
330 | - OpenFlow: | |
331 | - Added ability to match on IPv6 flow label through NXM. | |
332 | - Added ability to match on ECN bits in IPv4 and IPv6 through NXM. | |
333 | - Added ability to match on TTL in IPv4 and IPv6 through NXM. | |
334 | - Added ability to modify ECN bits in IPv4. | |
335 | - Added ability to modify TTL in IPv4. | |
336 | - ovs-vswitchd: | |
337 | - Don't require the "normal" action to use mirrors. Traffic will | |
338 | now be properly mirrored for any flows, regardless of their | |
339 | actions. | |
340 | - Track packet and byte statistics sent on mirrors. | |
341 | - The sFlow implementation can now usually infer the correct agent | |
342 | device instead of having to be told explicitly. | |
343 | - ovs-appctl: | |
344 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
345 | - ovs-test: | |
346 | - A new distributed testing tool that allows one to diagnose performance | |
347 | and connectivity issues. This tool currently is not included in RH or | |
348 | Xen packages. | |
349 | - RHEL packaging now supports integration with Red Hat network scripts. | |
350 | - bonding: | |
351 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
352 | to active-backup. SLB bonds carry significant risks with them | |
353 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
354 | users from running into. Users are advised to update any scripts or | |
355 | configuration which may be negatively impacted by explicitly setting | |
356 | the bond mode which they want to use. | |
357 | ||
358 | ||
359 | v1.3.0 - 09 Dec 2011 | |
360 | ------------------------ | |
361 | - OpenFlow: | |
362 | - Added an OpenFlow extension which allows the "output" action to accept | |
363 | NXM fields. | |
364 | - Added an OpenFlow extension for flexible learning. | |
365 | - Bumped number of NXM registers from four to five. | |
366 | - ovs-appctl: | |
367 | - New "version" command to determine version of running daemon. | |
368 | - If no argument is provided for "cfm/show", displays detailed | |
369 | information about all interfaces with CFM enabled. | |
370 | - If no argument is provided for "lacp/show", displays detailed | |
371 | information about all ports with LACP enabled. | |
372 | - ovs-dpctl: | |
373 | - New "set-if" command to modify a datapath port's configuration. | |
374 | - ovs-vswitchd: | |
375 | - The software switch now supports 255 OpenFlow tables, instead | |
376 | of just one. By default, only table 0 is consulted, but the | |
377 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
378 | tables. Tables 128 and above are reserved for use by the | |
379 | switch itself; please use only tables 0 through 127. | |
380 | - Add support for 802.1D spanning tree (STP). | |
381 | - Fragment handling extensions: | |
382 | - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4 | |
383 | fields are made available for matching in fragments with | |
384 | offset 0. | |
385 | - New NXM_NX_IP_FRAG match field for matching IP fragments (usable | |
386 | via "ip_frag" in ovs-ofctl). | |
387 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
388 | fragment handling policy. | |
389 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. | |
390 | By default it remains compatible with the old version and other | |
391 | standards-based implementations. | |
392 | - Flow setups are now processed in a round-robin manner across ports | |
393 | to prevent any single client from monopolizing the CPU and conducting | |
394 | a denial of service attack. | |
395 | - Added support for native VLAN tagging. A new "vlan_mode" | |
396 | parameter can be set for "port". Possible values: "access", | |
397 | "trunk", "native-tagged" and "native-untagged". | |
398 | - test-openflowd has been removed. Please use ovs-vswitchd instead. | |
399 | ||
400 | v1.2.0 - 03 Aug 2011 | |
401 | ------------------------ | |
402 | - New "ofproto" abstraction layer to ease porting to hardware | |
403 | switching ASICs. | |
404 | - Packaging for Red Hat Enterprise Linux 5.6 and 6.0. | |
405 | - Datapath support for Linux kernels up to 3.0. | |
406 | - OpenFlow: | |
407 | - New "bundle" and "bundle_load" action extensions. | |
408 | - Database: | |
409 | - Implement table unique constraints. | |
410 | - Support cooperative locking between callers. | |
411 | - ovs-dpctl: | |
412 | - New "-s" option for "show" command prints packet and byte | |
413 | counters for each port. | |
414 | - ovs-ofctl: | |
415 | - New "--readd" option for "replace-flows". | |
416 | - ovs-vsctl: | |
417 | - New "show" command to print an overview of configuration. | |
418 | - New "comment" command to add remark that explains intentions. | |
419 | - ovs-brcompatd has been rewritten to fix long-standing bugs. | |
420 | - ovs-openflowd has been renamed test-openflowd and moved into the | |
421 | tests directory. Its presence confused too many users. Please | |
422 | use ovs-vswitchd instead. | |
423 | - New ovs-benchmark utility to test flow setup performance. | |
424 | - A new log level "off" has been added. Configuring a log facility | |
425 | "off" prevents any messages from being logged to it. Previously, | |
426 | "emer" was effectively "off" because no messages were ever logged at | |
427 | level "emer". Now, errors that cause a process to exit are logged | |
428 | at "emer" level. | |
429 | - "configure" option --with-l26 has been renamed --with-linux, and | |
430 | --with-l26-source has been renamed --with-linux-source. The old | |
431 | names will be removed after the next release, so please update | |
432 | your scripts. | |
433 | - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and | |
434 | datapath/linux-2.6/compat-2.6 directories. | |
435 | - Feature removals: | |
436 | - Dropped support for "tun_id_from_cookie" OpenFlow extension. | |
437 | Please use the extensible match extensions instead. | |
438 | - Removed the Maintenance_Point and Monitor tables in an effort | |
439 | to simplify 802.1ag configuration. | |
440 | - Performance and scalability improvements | |
441 | - Bug fixes | |

497 | to ease debugging complex flow tables. | |
498 | - Database: | |
