1 | Post-v2.3.0 |
2 | --------------------- | |
db5076ee | 3 | - Added support for SFQ, FQ_CoDel and CoDel qdiscs. |
557570fa AW |
4 | - Add bash command-line completion support for ovs-vsctl Please check |
5 | utilities/ovs-command-compgen.INSTALL.md for how to use. | |
9d078ec2 BP |
6 | - The MAC learning feature now includes per-port fairness to mitigate |
7 | MAC flooding attacks. | |
18080541 BP |
8 | - New support for a "conjunctive match" OpenFlow extension, which |
9 | allows constructing OpenFlow matches of the form "field1 in | |
10 | {a,b,c...} AND field2 in {d,e,f...}" and generalizations. For details, | |
cc23805c | 11 | see documentation for the "conjunction" action in ovs-ofctl(8). |
423ede18 AW |
12 | - Add bash command-line completion support for ovs-appctl/ovs-dpctl/ |
13 | ovs-ofctl/ovsdb-tool commands. Please check | |
14 | utilities/ovs-command-compgen.INSTALL.md for how to use. | |
35f48b8b BP |
15 | - The "learn" action supports a new flag "delete_learned" that causes |
16 | the learned flows to be deleted when the flow with the "learn" action | |
17 | is deleted. | |
c1fc1411 JG |
18 | - Basic support for the Geneve tunneling protocol. It is not yet |
19 | possible to generate or match options. This is planned for a future | |
20 | release. The protocol is documented at | |
21 | http://tools.ietf.org/html/draft-gross-geneve-00 | |
a413195e | 22 | - The OVS database now reports controller rate limiting statistics. |
50b9699f | 23 | - sflow now exports information about LACP-based bonds, port names, and |
3d2912f2 | 24 | OpenFlow port numbers, as well as datapath performance counters. |
fceef209 DDP |
25 | - ovs-dpctl functionality is now available for datapaths integrated |
26 | into ovs-vswitchd, via ovs-appctl. Some existing ovs-appctl | |
27 | commands are now redundant and will be removed in a future | |
28 | release. See ovs-vswitchd(8) for details. | |
79fe0f46 | 29 | - OpenFlow: |
db5076ee JR |
30 | * OpenFlow 1.4 bundles are now supported, but for flow mod |
31 | messages only. 'atomic' bundles are not yet supported, and | |
32 | 'ordered' bundles are trivially supported, as all bundled | |
33 | messages are executed in the order they were added to the | |
34 | bundle regardless of the presence of the 'ordered' flag. | |
e60e935b | 35 | * IPv6 flow label and neighbor discovery fields are now modifiable. |
d3cb080e BP |
36 | * OpenFlow 1.5 extended registers are now supported. |
37 | * The OpenFlow 1.5 actset_output field is now supported. | |
38 | * OpenFlow 1.5 Copy-Field action is now supported. | |
39 | * OpenFlow 1.5 masked Set-Field action is now supported. | |
3c4e10fb | 40 | * OpenFlow 1.3+ table features requests are now supported (read-only). |
1b0ee636 | 41 | * Nicira extension "move" actions may now be included in action sets. |
2e34a6a3 SS |
42 | * "resubmit" actions may now be included in action sets. The resubmit |
43 | is executed last, and only if the action set has no "output" or "group" | |
44 | action. | |
ca26eb44 | 45 | * OpenFlow 1.4+ flow "importance" is now maintained in the flow table. |
0c4b9393 SH |
46 | * A new Netronome extension to OpenFlow 1.5+ allows control over the |
47 | fields hashed for OpenFlow select groups. See "selection_method" and | |
48 | related options in ovs-ofctl(8) for details. | |
db5076ee JR |
49 | - ovs-ofctl has a new '--bundle' option that makes the flow mod commands |
50 | ('add-flow', 'add-flows', 'mod-flows', 'del-flows', and 'replace-flows') | |
51 | use an OpenFlow 1.4 bundle to operate the modifications as a single | |
52 | transaction. If any of the flow mods in a transaction fail, none of | |
53 | them are executed. | |
54 | - ovs-ofctl 'add-flow' and 'add-flows' commands now accept arbitrary flow | |
55 | mods as an input by allowing the flow specification to start with an | |
56 | explicit 'add', 'modify', 'modify_strict', 'delete', or 'delete_strict' | |
57 | keyword. A missing keyword is treated as 'add', so this is fully | |
58 | backwards compatible. With the new '--bundle' option all the flow mods | |
59 | are executed as a single transaction using the new OpenFlow 1.4 bundles | |
60 | support. | |
4a1f9610 | 61 | - ovs-pki: Changed message digest algorithm from MD5 to SHA-1 because |
9ff33ca7 BP |
62 | MD5 is no longer secure and some operating systems have started to disable |
63 | it in OpenSSL. | |
09e25603 TW |
64 | - ovsdb-server: New OVSDB protocol extension allows inequality tests on |
65 | "optional scalar" columns. See ovsdb-server(1) for details. | |
ff495b63 BP |
66 | - ovs-vsctl now permits immutable columns in a new row to be modified in |
67 | the same transaction that creates the row. | |
0bc1b46a BP |
68 | - test-controller has been renamed ovs-testcontroller at request of users |
69 | who find it useful for testing basic OpenFlow setups. It is still not | |
70 | a necessary or desirable part of most Open vSwitch deployments. | |
cccf7e9d | 71 | - Support for travis-ci.org based continuous integration builds has been |
542cc9bb | 72 | added. Build failures are reported to build@openvswitch.org. See INSTALL.md |
cccf7e9d | 73 | file for additional details. |
bbda3a2f DV |
74 | - Support for the Rapid Spanning Tree Protocol (IEEE 802.1D-2004). |
75 | The implementation has been tested successfully against the Ixia Automated | |
76 | Network Validation Library (ANVL). | |
2f9dd77f | 77 | - Stats are no longer updated on fake bond interface. |
3e5aeeb5 | 78 | - Keep active bond slave selection across OVS restart. |
ec8f0f0c | 79 | - A simple wrapper script, 'ovs-docker', to integrate OVS with Docker |
62dbc5bd GS |
80 | containers. If and when there is a native integration of Open vSwitch |
81 | with Docker, the wrapper script will be retired. | |
e5a1caee JG |
82 | - Added support for DPDK Tunneling. VXLAN, GRE, and Geneve are supported |
83 | protocols. This is generic tunneling mechanism for userspace datapath. | |
962f9fa4 | 84 | - Support for multicast snooping (IGMPv1 and IGMPv2) |
3afcde43 | 85 | - Support for Linux kernels up to 4.0.x |
d5460484 GS |
86 | - The documentation now use the term 'destination' to mean one of syslog, |
87 | console or file for vlog logging instead of the previously used term | |
88 | 'facility'. | |
ac6073e3 | 89 | - Support for VXLAN Group Policy extension |
99eef98b DF |
90 | - Initial support for the IETF Auto-Attach SPBM draft standard. This |
91 | contains rudimentary support for the LLDP protocol as needed for | |
92 | Auto-Attach. | |
d4763d1d JP |
93 | - The default OpenFlow and OVSDB ports are now the IANA-assigned |
94 | numbers. OpenFlow is 6653 and OVSDB is 6640. | |
58397e6c | 95 | - Support for DPDK vHost. |
4752cc0c | 96 | - Support for outer UDP checksums in Geneve and VXLAN. |
d0d986a5 TG |
97 | - The kernel vports with dependencies are no longer part of the overall |
98 | openvswitch.ko but built and loaded automatically as individual kernel | |
99 | modules (vport-*.ko). | |
4237026e | 100 | - Support for STT tunneling. |
2c7ea589 JP |

e13440fc | 103 | v2.3.0 - 14 Aug 2014 |
c5cf1059 | 104 | --------------------- |
6dc53744 BP |
105 | - OpenFlow 1.1, 1.2, and 1.3 are now enabled by default in |
106 | ovs-vswitchd. | |
69d6040e JR |
107 | - Linux kernel datapath now has an exact match cache optimizing the |
108 | flow matching process. | |
109 | - Datapath flows now have partially wildcarded tranport port field | |
110 | matches. This reduces userspace upcalls, but increases the | |
111 | number of different masks in the datapath. The kernel datapath | |
112 | exact match cache removes the overhead of matching the incoming | |
113 | packets with the larger number of masks, but when paired with an | |
114 | older kernel module, some workloads may perform worse with the | |
115 | new userspace. | |
0877a018 | 116 | - Compatibility with autoconf 2.63 (previously >=2.64) |
c5cf1059 | 117 | |
012c3a52 | 118 | v2.2.0 - Internal Release |
bff46ebb | 119 | --------------------- |
1839c356 FL |
120 | - Internal ports are no longer brought up by default, because it |
121 | should be an administrator task to bring up devices as they are | |
122 | configured properly. | |
c3ccfe98 AZ |
123 | - ovs-vsctl now reports when ovs-vswitchd fails to create a new port or |
124 | bridge. | |
9500f505 TG |
125 | - Port creation and configuration errors are now stored in a new error |
126 | column of the Interface table and included in 'ovs-vsctl show'. | |
7868fbc6 BP |
127 | - The "ovsdbmonitor" graphical tool has been removed, because it was |
128 | poorly maintained and not widely used. | |
e3c7ed29 | 129 | - New "check-ryu" Makefile target for running Ryu tests for OpenFlow |
542cc9bb | 130 | controllers against Open vSwitch. See INSTALL.md for details. |
f51e8ccb | 131 | - Added IPFIX support for SCTP flows and templates for ICMPv4/v6 flows. |
0b114fa0 GS |
132 | - Upon the receipt of a SIGHUP signal, ovs-vswitchd no longer reopens its |
133 | log file (it will terminate instead). Please use 'ovs-appctl vlog/reopen' | |
134 | instead. | |
e2f3178f | 135 | - Support for Linux kernels up to 3.14. From Kernel 3.12 onwards OVS uses |
cb25142c | 136 | tunnel API for GRE and VXLAN. |
8a9562d2 | 137 | - Added DPDK support. |
a5ed8fe3 | 138 | - Added support for custom vlog patterns in Python |
f51e8ccb | 139 | |
bff46ebb | 140 | |
a3aabcd2 | 141 | v2.1.0 - 19 Mar 2014 |
b366c1f4 | 142 | --------------------- |
13751fd8 JR |
143 | - Address prefix tracking support for flow tables. New columns |
144 | "prefixes" in OVS-DB table "Flow_Table" controls which packet | |
145 | header fields are used for address prefix tracking. Prefix | |
146 | tracking allows the classifier to skip rules with longer than | |
147 | necessary prefixes, resulting in better wildcarding for datapath | |
148 | flows. Default configuration is to not use any fields for prefix | |
149 | tracking. However, if any flow tables contain both exact matches | |
150 | and masked matches for IP address fields, OVS performance may be | |
151 | increased by using this feature. | |
152 | * As of now, the fields for which prefix lookup can be enabled | |
153 | are: 'tun_id', 'tun_src', 'tun_dst', 'nw_src', 'nw_dst' (or | |
154 | aliases 'ip_src' and 'ip_dst'), 'ipv6_src', and 'ipv6_dst'. | |
155 | (Using this feature for 'tun_id' would only make sense if the | |
156 | tunnel IDs have prefix structure similar to IP addresses.) | |
157 | * There is a maximum number of fields that can be enabled for any | |
158 | one flow table. Currently this limit is 3. | |
159 | * Examples: | |
160 | $ ovs-vsctl set Bridge br0 flow_tables:0=@N1 -- \ | |
161 | --id=@N1 create Flow_Table name=table0 | |
162 | $ ovs-vsctl set Bridge br0 flow_tables:1=@N1 -- \ | |
163 | --id=@N1 create Flow_Table name=table1 | |
164 | $ ovs-vsctl set Flow_Table table0 prefixes=ip_dst,ip_src | |
165 | $ ovs-vsctl set Flow_Table table1 prefixes=[] | |
bcb8bde4 JR |
166 | - TCP flags matching: OVS now supports matching of TCP flags. This |
167 | has an adverse performance impact when using OVS userspace 1.10 | |
168 | or older (no megaflows support) together with the new OVS kernel | |
169 | module. It is recommended that the kernel and userspace modules | |
170 | both are upgraded at the same time. | |
36359150 JP |
171 | - The default OpenFlow and OVSDB ports will change to |
172 | IANA-assigned numbers in a future release. Consider updating | |
173 | your installations to specify port numbers instead of using the | |
174 | defaults. | |
7fdb60a7 SH |
175 | - OpenFlow: |
176 | * The OpenFlow 1.1+ "Write-Actions" instruction is now supported. | |
484c8355 BP |
177 | * OVS limits the OpenFlow port numbers it assigns to port 32767 and |
178 | below, leaving port numbers above that range free for assignment | |
179 | by the controller. | |
4abb8608 BP |
180 | * ovs-vswitchd now honors changes to the "ofport_request" column |
181 | in the Interface table by changing the port's OpenFlow port | |
182 | number. | |
5dc6f8e1 | 183 | * The Open vSwitch software switch now supports OpenFlow groups. |
a5ae88ff AA |
184 | - ovs-vswitchd.conf.db.5 man page will contain graphviz/dot |
185 | diagram only if graphviz package was installed at the build time. | |
54af97ad | 186 | - Support for Linux kernels up to 3.11 |
847108dc AZ |
187 | - ovs-dpctl: |
188 | The "show" command also displays mega flow mask stats. | |
60e46251 BP |
189 | - ovs-ofctl: |
190 | * New command "ofp-parse-pcap" to dump OpenFlow from PCAP files. | |
1d5aaa61 BP |
191 | - ovs-controller has been renamed test-controller. It is no longer |
192 | packaged or installed by default, because too many users assumed | |
193 | incorrectly that ovs-controller was a necessary or desirable part | |
194 | of an Open vSwitch deployment. | |
afc9f547 | 195 | - Added vlog option to export to a UDP syslog sink. |
4227b221 BP |
196 | - ovsdb-client: |
197 | * The "monitor" command can now monitor all tables in a database, | |
198 | instead of being limited to a single table. | |
e79a6c83 EJ |
199 | - The flow-eviction-threshold has been replaced by the flow-limit which is a |
200 | hard limit on the number of flows in the datapath. It defaults to 200,000 | |
201 | flows. OVS automatically adjusts this number depending on network | |
202 | conditions. | |
e731d71b | 203 | - Added IPv6 support for active and passive socket communications. |
b366c1f4 JP |
204 | |
205 | ||
2fdb1879 | 206 | v2.0.0 - 15 Oct 2013 |
9f31efc7 | 207 | --------------------- |
d27705ea JP |
208 | - The ovs-vswitchd process is no longer single-threaded. Multiple |
209 | threads are now used to handle flow set up and asynchronous | |
210 | logging. | |
0ad90c84 | 211 | - OpenFlow: |
75fa58f8 BP |
212 | * Experimental support for OpenFlow 1.1 (in addition to 1.2 and |
213 | 1.3, which had experimental support in 1.10). | |
7395c052 NZ |
214 | * Experimental protocol support for OpenFlow 1.1+ groups. This |
215 | does not yet include an implementation in the Open vSwitch | |
216 | software switch. | |
217 | * Experimental protocol support for OpenFlow 1.2+ meters. This | |
218 | does not yet include an implementation in the Open vSwitch | |
219 | software switch. | |
0ad90c84 JR |
220 | * New support for matching outer source and destination IP address |
221 | of tunneled packets, for tunnel ports configured with the newly | |
e0eeeca5 | 222 | added "remote_ip=flow" and "local_ip=flow" options. |
ac923e91 JG |
223 | * Support for matching on metadata 'pkt_mark' for interacting with |
224 | other system components. On Linux this corresponds to the skb | |
225 | mark. | |
fe8a1798 | 226 | * Support matching, rewriting SCTP ports |
ea401d9a NM |
227 | - The Interface table in the database has a new "ifindex" column to |
228 | report the interface's OS-assigned ifindex. | |
81a114e5 BP |
229 | - New "check-oftest" Makefile target for running OFTest against Open |
230 | vSwitch. See README-OFTest for details. | |
380f49c4 | 231 | - The flow eviction threshold has been moved to the Open_vSwitch table. |
fb6de52c GS |
232 | - Database names are now mandatory when specifying ovsdb-server options |
233 | through database paths (e.g. Private key option with the database name | |
234 | should look like "--private-key=db:Open_vSwitch,SSL,private_key"). | |
fef5244f | 235 | - Added ovs-dev.py, a utility script helpful for Open vSwitch developers. |
9b764edf | 236 | - Support for Linux kernels up to 3.10 |
1ac0e975 BP |
237 | - ovs-ofctl: |
238 | * New "ofp-parse" for printing OpenFlow messages read from a file. | |
7395c052 | 239 | * New commands for OpenFlow 1.1+ groups. |
978427a5 | 240 | - Added configurable flow caching support to IPFIX exporter. |
37418c86 | 241 | - Dropped support for Linux pre-2.6.32. |
7c018033 BP |
242 | - Log file timestamps and ovsdb commit timestamps are now reported |
243 | with millisecond resolution. (Previous versions only reported | |
244 | whole seconds.) | |
9f31efc7 JP |
245 | |
246 | ||
03c8f0b7 | 247 | v1.11.0 - 28 Aug 2013 |
d224e350 | 248 | --------------------- |
d445cc16 JP |
249 | - Support for megaflows, which allows wildcarding in the kernel (and |
250 | any dpif implementation that supports wildcards). Depending on | |
251 | the flow table and switch configuration, flow set up rates are | |
252 | close to the Linux bridge. | |
eeecce05 BP |
253 | - The "tutorial" directory contains a new tutorial for some advanced |
254 | Open vSwitch features. | |
df53d41c | 255 | - Stable bond mode has been removed. |
1bda9b9e | 256 | - The autopath action has been removed. |
a6ae068b LJ |
257 | - New support for the data encapsulation format of the LISP tunnel |
258 | protocol (RFC 6830). An external control plane or manual flow | |
259 | setup is required for EID-to-RLOC mapping. | |
b676167a | 260 | - OpenFlow: |
0f3f3c3d SH |
261 | * The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow |
262 | 1.1 and later are now implemented. | |
bd85dac1 AZ |
263 | * New "stack" extension for use in actions, to push and pop from |
264 | NXM fields. | |
a7b07d4c BP |
265 | * The "load" and "set_field" actions can now modify the "in_port". (This |
266 | allows one to enable output to a flow's input port by setting the | |
267 | in_port to some unused value, such as OFPP_NONE.) | |
186afbfe BP |
268 | - ovs-dpctl: |
269 | * New debugging commands "add-flow", "mod-flow", "del-flow". | |
041e7168 | 270 | * "dump-flows" now has a -m option to increase output verbosity. |
bcd2633a JP |
271 | - In dpif-based bridges, cache action translations, which can improve |
272 | flow set up performance by 80% with a complicated flow table. | |
ca03aae0 | 273 | - New syslog format, prefixed with "ovs|", to be easier to filter. |
f9ee9dcb GS |
274 | - RHEL: Removes the default firewall rule that allowed GRE traffic to |
275 | pass through. Any users that relied on this automatic firewall hole | |
276 | will have to manually configure it. The ovs-ctl(8) manpage documents | |
277 | the "enable-protocol" command that can be used as an alternative. | |
90967e95 EJ |
278 | - New CFM demand mode which uses data traffic to indicate interface |
279 | liveness. | |
d224e350 | 280 | |
b82b19e9 | 281 | v1.10.0 - 01 May 2013 |
4191f435 | 282 | --------------------- |
685e46da BP |
283 | - Bridge compatibility support has been removed. Any uses that |
284 | rely on ovs-brcompatd will have to stick with Open vSwitch 1.9.x | |
285 | or adapt to native Open vSwitch support (e.g. use ovs-vsctl instead | |
286 | of brctl). | |
c4069512 | 287 | - The maximum size of the MAC learning table is now configurable. |
989fd548 JP |
288 | - With the Linux datapath, packets for new flows are now queued |
289 | separately on a per-port basis, so it should no longer be | |
290 | possible for a large number of new flows arriving on one port to | |
291 | prevent new flows from being processed on other ports. | |
43d18dc1 BP |
292 | - ovs-vsctl: |
293 | * Previously ovs-vsctl would retry connecting to the database forever, | |
294 | causing it to hang if ovsdb-server was not running. Now, ovs-vsctl | |
295 | only tries once by default (use --retry to try forever). This change | |
296 | means that you may want to remove uses of --timeout to avoid hangs | |
297 | in ovs-vsctl calls. | |
298 | * Many "ovs-vsctl" database commands now accept an --if-exists option. | |
299 | Please refer to the ovs-vsctl manpage for details. | |
e6024057 | 300 | - OpenFlow: |
d6123831 JP |
301 | - Experimental support for newer versions of OpenFlow. See |
302 | the "What versions of OpenFlow does Open vSwitch support?" | |
303 | question in the FAQ for more details. | |
e6024057 JP |
304 | - The OpenFlow "dp_desc" may now be configured by setting the |
305 | value of other-config:dp-desc in the Bridge table. | |
306 | - It is possible to request the OpenFlow port number with the | |
307 | "ofport_request" column in the Interface table. | |
c9accf5b BP |
308 | - The NXM flow_removed message now reports the OpenFlow table ID |
309 | from which the flow was removed. | |
3c23e920 JP |
310 | - Tunneling: |
311 | - New support for the VXLAN tunnel protocol (see the IETF draft here: | |
238bc978 | 312 | http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03). |
3c23e920 JP |
313 | - Tunneling requires the version of the kernel module paired with |
314 | Open vSwitch 1.9.0 or later. | |
315 | - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit) | |
316 | is no longer supported. | |
317 | - Path MTU discovery is no longer supported. | |
ccd989e0 JG |
318 | - CAPWAP tunneling support removed. |
319 | - Tunnels with multicast destination ports are no longer supported. | |
e6024057 JP |
320 | - ovs-dpctl: |
321 | - The "dump-flows" and "del-flows" no longer require an argument | |
322 | if only one datapath exists. | |
323 | - ovs-appctl: | |
324 | - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit" | |
325 | commands available allow control over logging rate limits. | |
326 | - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command | |
327 | that mimic the equivalent ovs-dpctl commands. | |
e6024057 JP |
328 | - The ofproto library is now responsible for assigning OpenFlow port |
329 | numbers. An ofproto implementation should assign them when | |
330 | port_construct() is called. | |
331 | - All dpif-based bridges of a particular type share a common | |
332 | datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl | |
333 | commands will now return information on that shared datapath. To | |
334 | get the equivalent bridge-specific information, use the new | |
335 | "ovs-appctl dpif/*" commands. | |
bedde04c GS |
336 | - Backward-incompatible changes: |
337 | - Earlier Open vSwitch versions treated ANY as a wildcard in flow | |
338 | syntax. OpenFlow 1.1 adds a port named ANY, which introduces a | |
339 | conflict. ANY was rarely used in flow syntax, so we chose to | |
340 | retire that meaning of ANY in favor of the OpenFlow 1.1 meaning. | |
3c23e920 JP |
341 | - Patch ports no longer require kernel support, so they now work |
342 | with FreeBSD and the kernel module built into Linux 3.3 and later. | |
29089a54 | 343 | - New "sample" action. |
f07ee64c | 344 | |
e5f77cc3 | 345 | |
fdfe872d JP |
346 | v1.9.0 - 26 Feb 2013 |
347 | ------------------------ | |
72e8bf28 AA |
348 | - Datapath: |
349 | - Support for ipv6 set action. | |
350 | - SKB mark matching and setting. | |
64807dfb | 351 | - support for Linux kernels up to 3.8 |
f6eb6b20 GL |
352 | - FreeBSD is now a supported platform, thanks to code contributions from |
353 | Gaetano Catalli, Ed Maste, and Giuseppe Lettieri. | |
b592e726 | 354 | - ovs-bugtool: New --ovs option to report only OVS related information. |
781dee08 BP |
355 | - New %t and %T log escapes to identify the subprogram within a |
356 | cooperating group of processes or threads that emitted a log message. | |
357 | The default log patterns now include this information. | |
32455024 | 358 | - OpenFlow: |
e878338b SH |
359 | - Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL |
360 | fields in IPv6 neighbor discovery messages, and IPv6 flow label. | |
4cceacb9 | 361 | - Adds support for writing to the metadata field for a flow. |
3c23e920 JP |
362 | - Tunneling: |
363 | - The tunneling code no longer assumes input and output keys are | |
364 | symmetric. If they are not, PMTUD needs to be disabled for | |
365 | tunneling to work. Note this only applies to flow-based keys. | |
366 | - New support for a nonstandard form of GRE that supports a 64-bit key. | |
367 | - Tunnel Path MTU Discovery default value was set to 'disabled'. | |
368 | This feature is deprecated and will be removed soon. | |
369 | - Tunnel header caching removed. | |
c6100d92 BP |
370 | - ovs-ofctl: |
371 | - Commands and actions that accept port numbers now also accept keywords | |
372 | that represent those ports (such as LOCAL, NONE, and ALL). This is | |
373 | also the recommended way to specify these ports, for compatibility | |
374 | with OpenFlow 1.1 and later (which use the OpenFlow 1.0 numbers | |
375 | for these ports for different purposes). | |
2562714a | 376 | - ovs-dpctl: |
4b3b8d8f JP |
377 | - Support requesting the port number with the "port_no" option in |
378 | the "add-if" command. | |
2562714a BP |
379 | - ovs-pki: The "online PKI" features have been removed, along with |
380 | the ovs-pki-cgi program that facilitated it, because of some | |
381 | alarmist insecurity claims. We do not believe that these claims | |
382 | are true, but because we do not know of any users for this | |
383 | feature it seems better on balance to remove it. (The ovs-pki-cgi | |
384 | program was not included in distribution packaging.) | |
341c4e59 BP |
385 | - ovsdb-server now enforces the immutability of immutable columns. This |
386 | was not enforced in earlier versions due to an oversight. | |
fd38af85 BP |
387 | - The following features are now deprecated. They will be removed no |
388 | earlier than February 2013. Please email dev@openvswitch.org with | |
389 | concerns. | |
a8643e44 | 390 | - Bridge compatibility. |
fd38af85 BP |
391 | - Stable bond mode. |
392 | - The autopath action. | |
393 | - Interface type "null". | |
394 | - Numeric values for reserved ports (see "ovs-ofctl" note above). | |
85340733 | 395 | - Tunnel Path MTU Discovery. |
1280bf0e | 396 | - CAPWAP tunnel support. |
f07ee64c MM |
397 | - The data in the RARP packets can now be matched in the same way as the |
398 | data in ARP packets. | |
945cad7f | 399 | |
79f827fa | 400 | |
fdfe872d | 401 | v1.8.0 - 26 Feb 2013 |

406 | Reproduction" in DESIGN, which describes an Open vSwitch change in | |
407 | behavior in corner cases that may affect some controllers. | |
2d8bdd8f AA |
408 | - ovs-l3ping: |
409 | - A new test utility that can create L3 tunnel between two Open | |
410 | vSwitches and detect connectivity issues. | |

ff0b06ee BP |
415 | - Allow general bitwise masking for IPv4 and IPv6 addresses in |
416 | IPv4, IPv6, and ARP packets. (Previously, only CIDR masks | |
c08201d6 BP |
417 | were allowed.) |
418 | - Allow support for arbitrary Ethernet masks. (Previously, only | |
419 | the multicast bit in the destination address could be individually | |
420 | masked.) | |
969fc56c | 421 | - New field OXM_OF_METADATA, to align with OpenFlow 1.1. |
0414d158 BP |
422 | - The OFPST_QUEUE request now reports an error if a specified port or |
423 | queue does not exist, or for requests for a specific queue on all | |
424 | ports, if the specified queue does not exist on any port. (Previous | |
425 | versions generally reported an empty set of results.) | |
2b07c8b1 BP |
426 | - New "flow monitor" feature to allow controllers to be notified of |
427 | flow table changes as they happen. | |
c93f9a78 EJ |
428 | - Additional protocols are not mirrored and dropped when forward-bpdu is |
429 | false. For a full list, see the ovs-vswitchd.conf.db man page. | |
38f7147c EJ |
430 | - Open vSwitch now sends RARP packets in situations where it previously |
431 | sent a custom protocol, making it consistent with behavior of QEMU and | |
432 | VMware. | |
969e46a2 AS |
433 | - All Open vSwitch programs and log files now show timestamps in UTC, |
434 | instead the local timezone, by default. | |
c8d5d22c JP |
435 | |
436 | ||
3b4ab170 | 437 | v1.7.0 - 30 Jul 2012 |
dd1ba5b3 | 438 | ------------------------ |
9b80f761 CW |

444 | Internetwork Control (0xc0). | |
3967a833 MM |
445 | - Added the granular link health statistics, 'cfm_health', to an |
446 | interface. | |
47284b1f AA |
447 | - OpenFlow: |
448 | - Added support to mask nd_target for ICMPv6 neighbor discovery flows. | |
2be393ed JP |
449 | - Added support for OpenFlow 1.3 port description (OFPMP_PORT_DESC) |
450 | multipart messages. | |
451 | - ovs-ofctl: | |
452 | - Added the "dump-ports-desc" command to retrieve port | |
453 | information using the new port description multipart messages. | |
8d25d9a2 AA |
454 | - ovs-test: |
455 | - Added support for spawning ovs-test server from the client. | |
456 | - Now ovs-test is able to automatically create test bridges and ports. | |
7393104d | 457 | - "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows. |
22dd5cec | 458 | - Tripled flow setup performance. |
a5f607bc BP |
459 | - The "coverage/log" command previously available through ovs-appctl |
460 | has been replaced by "coverage/show". The new command replies with | |
461 | coverage counter values, instead of logging them. | |
dd1ba5b3 JP |
462 | |
463 | ||
9d564cb2 | 464 | v1.6.1 - 25 Jun 2012 |

470 | ------------------------ | |
471 | *** Internal only release *** | |
4df08875 | 472 | - bonding |
bdebeece EJ |
473 | - LACP bonds no longer fall back to balance-slb when negotiations fail. |
474 | Instead they drop traffic. | |
4df08875 EJ |
475 | - The default bond_mode changed from SLB to active-backup, to protect |
476 | unsuspecting users from the significant risks of SLB bonds (which are | |
477 | documented in vswitchd/INTERNALS). | |
bc1b010c EJ |
478 | - Load balancing can be disabled by setting the bond-rebalance-interval |
479 | to zero. | |
73f33563 BP |
480 | - OpenFlow: |
481 | - Added support for bitwise matching on TCP and UDP ports. | |
482 | See ovs-ofctl(8) for more information. | |
80d5aefd BP |
483 | - NXM flow dumps now include times elapsed toward idle and hard |
484 | timeouts. | |
485 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |
486 | controllers more precise control over which OpenFlow messages they | |
487 | receive asynchronously. | |
0e553d9c BP |
488 | - New "fin_timeout" action. |
489 | - Added "fin_timeout" support to "learn" action. | |
a7349929 BP |
490 | - New Nicira action NXAST_CONTROLLER that offers additional features |
491 | over output to OFPP_CONTROLLER. | |
2c999774 BP |
492 | - When QoS settings for an interface do not configure a default queue |
493 | (queue 0), Open vSwitch now uses a default configuration for that | |
494 | queue, instead of dropping all packets as in previous versions. | |
2a3e30b2 BP |
495 | - Logging: |
496 | - Logging to console and file will have UTC timestamp as a default for | |
497 | all the daemons. An example of the default format is | |
498 | 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default | |
499 | format as before. | |
500 | - The syntax of commands and options to set log levels was simplified, | |
501 | to make it easier to remember. | |
254750ce BP |
502 | - New support for limiting the number of flows in an OpenFlow flow |
503 | table, with configurable policy for evicting flows upon | |
504 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
505 | for more information. | |
9886b662 BP |
506 | - New "enable-async-messages" column in the Controller table. If set to |
507 | false, OpenFlow connections to the controller will initially have all | |
508 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
1745cd08 BP |
509 | - ofproto-provider interface: |
510 | - "struct rule" has a new member "used" that ofproto implementations | |
511 | should maintain by updating with ofproto_rule_update_used(). | |
8f46c9bb BP |
512 | - ovsdb-client: |
513 | - The new option --timestamp causes the "monitor" command to print | |
514 | a timestamp with every update. | |
a7aa2d3c | 515 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. |
d0a8c2e0 JP |

531 | directories as defaults. | |
d1add61d JP |
532 | - The default MAC learning timeout has been increased from 60 seconds |
533 | to 300 seconds. The MAC learning timeout is now configurable. | |
e68bfcfc JP |
534 | |

ef13dc11 | 536 | v1.4.0 - 30 Jan 2012 |
b6a9a95b | 537 | ------------------------ |
50bf17cd | 538 | - Compatible with Open vSwitch kernel module included in Linux 3.3. |
52a90c29 BP |
539 | - New "VLAN splinters" feature to work around buggy device drivers |
540 | in old Linux versions. (This feature is deprecated. When | |
541 | broken device drivers are no longer in widespread use, we will | |
542 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
543 | information. | |
fa8223b7 JP |
544 | - OpenFlow: |
545 | - Added ability to match on IPv6 flow label through NXM. | |

a61680c6 | 547 | - Added ability to match on TTL in IPv4 and IPv6 through NXM. |
530180fd | 548 | - Added ability to modify ECN bits in IPv4. |
a61680c6 | 549 | - Added ability to modify TTL in IPv4. |
9d24de3b | 550 | - ovs-vswitchd: |
c06bba01 JP |
551 | - Don't require the "normal" action to use mirrors. Traffic will |
552 | now be properly mirrored for any flows, regardless of their | |
553 | actions. | |
9d24de3b | 554 | - Track packet and byte statistics sent on mirrors. |
733adf2a LG |
555 | - The sFlow implementation can now usually infer the correct agent |
556 | device instead of having to be told explicitly. | |
f0a3aa2e AA |
557 | - ovs-appctl: |
558 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
0be6140a AA |
559 | - ovs-test: |
560 | - A new distributed testing tool that allows one to diagnose performance | |
561 | and connectivity issues. This tool currently is not included in RH or | |
562 | Xen packages. | |
0fb42626 | 563 | - RHEL packaging now supports integration with Red Hat network scripts. |
4c57c3bc EJ |
564 | - bonding: |
565 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
566 | to active-backup. SLB bonds carry significant risks with them | |
567 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
568 | users from running into. Users are advised to update any scripts or | |
569 | configuration which may be negatively impacted by explicitly setting | |
570 | the bond mode which they want to use. | |
b6a9a95b | 571 | |
0be6140a | 572 | |

577 | NXM fields. | |
75a75043 | 578 | - Added an OpenFlow extension for flexible learning. |
d2c0fed9 | 579 | - Bumped number of NXM registers from four to five. |
d5e1e5ed | 580 | - ovs-appctl: |
ae75dae3 JP |
581 | - New "version" command to determine version of running daemon. |
582 | - If no argument is provided for "cfm/show", displays detailed | |
583 | information about all interfaces with CFM enabled. | |
5dab8ece JP |
584 | - If no argument is provided for "lacp/show", displays detailed |
585 | information about all ports with LACP enabled. | |

587 | - New "set-if" command to modify a datapath port's configuration. | |
29901626 BP |
588 | - ovs-vswitchd: |
589 | - The software switch now supports 255 OpenFlow tables, instead | |
590 | of just one. By default, only table 0 is consulted, but the | |
591 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
592 | tables. Tables 128 and above are reserved for use by the | |
593 | switch itself; please use only tables 0 through 127. | |
21f7563c | 594 | - Add support for 802.1D spanning tree (STP). |
7257b535 BP |
595 | - Fragment handling extensions: |
596 | - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4 | |
597 | fields are made available for matching in fragments with | |
598 | offset 0. | |
599 | - New NXM_NX_IP_FRAG match field for matching IP fragments (usable | |
600 | via "ip_frag" in ovs-ofctl). | |
601 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
602 | fragment handling policy. | |
2f4bc10d BP |
603 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. |
604 | By default it remains compatible with the old version and other | |
c87112ca | 605 | standards-based implementations. |
17411ecf JG |
606 | - Flow setups are now processed in a round-robin manner across ports |
607 | to prevent any single client from monopolizing the CPU and conducting | |
608 | a denial of service attack. | |
ecac4ebf BP |
609 | - Added support for native VLAN tagging. A new "vlan_mode" |
610 | parameter can be set for "port". Possible values: "access", | |
611 | "trunk", "native-tagged" and "native-untagged". | |
023e1e0a | 612 | - test-openflowd has been removed. Please use ovs-vswitchd instead. |

616 | - New "ofproto" abstraction layer to ease porting to hardware |
617 | switching ASICs. | |
618 | - Packaging for Red Hat Enterprise Linux 5.6 and 6.0. | |
619 | - Datapath support for Linux kernels up to 3.0. | |
620 | - OpenFlow: | |
621 | - New "bundle" and "bundle_load" action extensions. | |
622 | - Database: | |
623 | - Implement table unique constraints. | |
624 | - Support cooperative locking between callers. | |
625 | - ovs-dpctl: | |
626 | - New "-s" option for "show" command prints packet and byte | |
627 | counters for each port. | |
c4ea79bf BP |
628 | - ovs-ofctl: |
629 | - New "--readd" option for "replace-flows". | |
9b1735a7 BP |

631 | - New "show" command to print an overview of configuration. | |
1a142ced | 632 | - New "comment" command to add remark that explains intentions. |
2b01925c | 633 | - ovs-brcompatd has been rewritten to fix long-standing bugs. |
045b2e5c BP |
634 | - ovs-openflowd has been renamed test-openflowd and moved into the |
635 | tests directory. Its presence confused too many users. Please | |
636 | use ovs-vswitchd instead. | |
1a142ced JP |
637 | - New ovs-benchmark utility to test flow setup performance. |
638 | - A new log level "off" has been added. Configuring a log facility | |
639 | "off" prevents any messages from being logged to it. Previously, | |
640 | "emer" was effectively "off" because no messages were ever logged at | |
641 | level "emer". Now, errors that cause a process to exit are logged | |
642 | at "emer" level. | |
8a2d6596 BP |
643 | - "configure" option --with-l26 has been renamed --with-linux, and |
644 | --with-l26-source has been renamed --with-linux-source. The old | |
645 | names will be removed after the next release, so please update | |
646 | your scripts. | |
22bcc0e7 JG |
647 | - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and |
648 | datapath/linux-2.6/compat-2.6 directories. | |
b78f6b77 BP |
649 | - Feature removals: |
650 | - Dropped support for "tun_id_from_cookie" OpenFlow extension. | |
0be6140a | 651 | Please use the extensible match extensions instead. |
93b8df38 EJ |
652 | - Removed the Maintenance_Point and Monitor tables in an effort |
653 | to simplify 802.1ag configuration. | |
1a142ced JP |
654 | - Performance and scalability improvements |
655 | - Bug fixes | |
b78f6b77 | 656 | |
d4da3acc JP |

727 | - Many "name" columns are now immutable. | |
728 | - Feature removals: | |
729 | - Dropped support for XenServer pre-5.6.100. | |
730 | - Dropped support for Linux pre-2.6.18. | |
731 | - Dropped controller discovery support. | |

733 | Statistics reporting in the database is a rough equivalent. | |
734 | - Dropped the "corekeeper" package (now separate, at | |
735 | http://openvswitch.org/cgi-bin/gitweb.cgi?p=corekeeper). | |
