1 | post-v1.7.0 | |
2 | ------------------------ | |
3 | - New FAQ. Please send updates and additions! | |
4 | - ovs-ofctl: | |
5 | - "mod-port" command can now control all OpenFlow config flags. | |
6 | - OpenFlow: | |
7 | - Allow general bitwise masking for IPv4 and IPv6 addresses in | |
8 | IPv4, IPv6, and ARP packets. (Previously, only CIDR masks | |
9 | were allowed.) | |
10 | - Allow support for arbitrary Ethernet masks. (Previously, only | |
11 | the multicast bit in the destination address could be individually | |
12 | masked.) | |
13 | - New field OXM_OF_METADATA, to align with OpenFlow 1.1. | |
14 | - Additional protocols are not mirrored and dropped when forward-bpdu is | |
15 | false. For a full list, see the ovs-vswitchd.conf.db man page. | |
16 | - Open vSwitch now sends RARP packets in situations where it previously | |
17 | sent a custom protocol, making it consistent with behavior of QEMU and | |
18 | VMware. | |
19 | ||
20 | ||
21 | v1.7.0 - xx xxx xxxx | |
22 | ------------------------ | |
23 | - kernel modules are renamed. openvswitch_mod.ko is now | |
24 | openvswitch.ko and brcompat_mod.ko is now brcompat.ko. | |
25 | - Increased the number of NXM registers to 8. | |
26 | - Added ability to configure dscp setting for manager and controller | |
27 | connections. By default, these connections have a DSCP value of | |
28 | Internetwork Control (0xc0). | |
29 | - Added the granular link health statistics, 'cfm_health', to an | |
30 | interface. | |
31 | - OpenFlow: | |
32 | - Added support to mask nd_target for ICMPv6 neighbor discovery flows. | |
33 | - Added support for OpenFlow 1.3 port description (OFPMP_PORT_DESC) | |
34 | multipart messages. | |
35 | - ovs-ofctl: | |
36 | - Added the "dump-ports-desc" command to retrieve port | |
37 | information using the new port description multipart messages. | |
38 | - ovs-test: | |
39 | - Added support for spawning ovs-test server from the client. | |
40 | - Now ovs-test is able to automatically create test bridges and ports. | |
41 | - "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows. | |
42 | - The "coverage/log" command previously available through ovs-appctl | |
43 | has been replaced by "coverage/show". The new command replies with | |
44 | coverage counter values, instead of logging them. | |
45 | ||
46 | ||
47 | v1.6.1 - 25 Jun 2012 | |
48 | ------------------------ | |
49 | - Allow OFPP_CONTROLLER as the in_port for packet-out messages. | |
50 | ||
51 | ||
52 | v1.6.0 - 24 Feb 2012 | |
53 | ------------------------ | |
54 | *** Internal only release *** | |
55 | - bonding | |
56 | - LACP bonds no longer fall back to balance-slb when negotiations fail. | |
57 | Instead they drop traffic. | |
58 | - The default bond_mode changed from SLB to active-backup, to protect | |
59 | unsuspecting users from the significant risks of SLB bonds (which are | |
60 | documented in vswitchd/INTERNALS). | |
61 | - Load balancing can be disabled by setting the bond-rebalance-interval | |
62 | to zero. | |
63 | - OpenFlow: | |
64 | - Added support for bitwise matching on TCP and UDP ports. | |
65 | See ovs-ofctl(8) for more information. | |
66 | - NXM flow dumps now include times elapsed toward idle and hard | |
67 | timeouts. | |
68 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |
69 | controllers more precise control over which OpenFlow messages they | |
70 | receive asynchronously. | |
71 | - New "fin_timeout" action. | |
72 | - Added "fin_timeout" support to "learn" action. | |
73 | - New Nicira action NXAST_CONTROLLER that offers additional features | |
74 | over output to OFPP_CONTROLLER. | |
75 | - When QoS settings for an interface do not configure a default queue | |
76 | (queue 0), Open vSwitch now uses a default configuration for that | |
77 | queue, instead of dropping all packets as in previous versions. | |
78 | - Logging: | |
79 | - Logging to console and file will have UTC timestamp as a default for | |
80 | all the daemons. An example of the default format is | |
81 | 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default | |
82 | format as before. | |
83 | - The syntax of commands and options to set log levels was simplified, | |
84 | to make it easier to remember. | |
85 | - New support for limiting the number of flows in an OpenFlow flow | |
86 | table, with configurable policy for evicting flows upon | |
87 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
88 | for more information. | |
89 | - New "enable-async-messages" column in the Controller table. If set to | |
90 | false, OpenFlow connections to the controller will initially have all | |
91 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
92 | - ofproto-provider interface: | |
93 | - "struct rule" has a new member "used" that ofproto implementations | |
94 | should maintain by updating with ofproto_rule_update_used(). | |
95 | - ovsdb-client: | |
96 | - The new option --timestamp causes the "monitor" command to print | |
97 | a timestamp with every update. | |
98 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. | |
99 | ||
100 | ||
101 | v1.5.0 - 01 Jun 2012 | |
102 | ------------------------ | |
103 | - OpenFlow: | |
104 | - Added support for querying, modifying, and deleting flows | |
105 | based on flow cookie when using NXM. | |
106 | - Added new NXM_PACKET_IN format. | |
107 | - Added new NXAST_DEC_TTL action. | |
108 | - ovs-ofctl: | |
109 | - Added daemonization support to the monitor and snoop commands. | |
110 | - ovs-vsctl: | |
111 | - The "find" command supports new set relational operators | |
112 | {=}, {!=}, {<}, {>}, {<=}, and {>=}. | |
113 | - ovsdb-tool now uses the typical database and schema installation | |
114 | directories as defaults. | |
115 | - The default MAC learning timeout has been increased from 60 seconds | |
116 | to 300 seconds. The MAC learning timeout is now configurable. | |
117 | ||
118 | ||
119 | v1.4.0 - 30 Jan 2012 | |
120 | ------------------------ | |
121 | - Compatible with Open vSwitch kernel module included in Linux 3.3. | |
122 | - New "VLAN splinters" feature to work around buggy device drivers | |
123 | in old Linux versions. (This feature is deprecated. When | |
124 | broken device drivers are no longer in widespread use, we will | |
125 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
126 | information. | |
127 | - OpenFlow: | |
128 | - Added ability to match on IPv6 flow label through NXM. | |
129 | - Added ability to match on ECN bits in IPv4 and IPv6 through NXM. | |
130 | - Added ability to match on TTL in IPv4 and IPv6 through NXM. | |
131 | - Added ability to modify ECN bits in IPv4. | |
132 | - Added ability to modify TTL in IPv4. | |
133 | - ovs-vswitchd: | |
134 | - Don't require the "normal" action to use mirrors. Traffic will | |
135 | now be properly mirrored for any flows, regardless of their | |
136 | actions. | |
137 | - Track packet and byte statistics sent on mirrors. | |
138 | - The sFlow implementation can now usually infer the correct agent | |
139 | device instead of having to be told explicitly. | |
140 | - ovs-appctl: | |
141 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
142 | - ovs-test: | |
143 | - A new distributed testing tool that allows one to diagnose performance | |
144 | and connectivity issues. This tool currently is not included in RH or | |
145 | Xen packages. | |
146 | - RHEL packaging now supports integration with Red Hat network scripts. | |
147 | - bonding: | |
148 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
149 | to active-backup. SLB bonds carry significant risks with them | |
150 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
151 | users from running into. Users are advised to update any scripts or | |
152 | configuration which may be negatively impacted by explicitly setting | |
153 | the bond mode which they want to use. | |
154 | ||
155 | ||
156 | v1.3.0 - 09 Dec 2011 | |
157 | ------------------------ | |
158 | - OpenFlow: | |
159 | - Added an OpenFlow extension which allows the "output" action to accept | |
160 | NXM fields. | |
161 | - Added an OpenFlow extension for flexible learning. | |
162 | - Bumped number of NXM registers from four to five. | |
163 | - ovs-appctl: | |
164 | - New "version" command to determine version of running daemon. | |
165 | - If no argument is provided for "cfm/show", displays detailed | |
166 | information about all interfaces with CFM enabled. | |
167 | - If no argument is provided for "lacp/show", displays detailed | |
168 | information about all ports with LACP enabled. | |
169 | - ovs-dpctl: | |
170 | - New "set-if" command to modify a datapath port's configuration. | |
171 | - ovs-vswitchd: | |
172 | - The software switch now supports 255 OpenFlow tables, instead | |
173 | of just one. By default, only table 0 is consulted, but the | |
174 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
175 | tables. Tables 128 and above are reserved for use by the | |
176 | switch itself; please use only tables 0 through 127. | |
177 | - Add support for 802.1D spanning tree (STP). | |
178 | - Fragment handling extensions: | |
179 | - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4 | |
180 | fields are made available for matching in fragments with | |
181 | offset 0. | |
182 | - New NXM_NX_IP_FRAG match field for matching IP fragments (usable | |
183 | via "ip_frag" in ovs-ofctl). | |
184 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
185 | fragment handling policy. | |
186 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. | |
187 | By default it remains compatible with the old version and other | |
188 | standards-based implementations. | |
189 | - Flow setups are now processed in a round-robin manner across ports | |
190 | to prevent any single client from monopolizing the CPU and conducting | |
191 | a denial of service attack. | |
192 | - Added support for native VLAN tagging. A new "vlan_mode" | |
193 | parameter can be set for "port". Possible values: "access", | |
194 | "trunk", "native-tagged" and "native-untagged". | |
195 | - test-openflowd has been removed. Please use ovs-vswitchd instead. | |
196 | ||
197 | v1.2.0 - 03 Aug 2011 | |
198 | ------------------------ | |
199 | - New "ofproto" abstraction layer to ease porting to hardware | |
200 | switching ASICs. | |
201 | - Packaging for Red Hat Enterprise Linux 5.6 and 6.0. | |
202 | - Datapath support for Linux kernels up to 3.0. | |
203 | - OpenFlow: | |
204 | - New "bundle" and "bundle_load" action extensions. | |
205 | - Database: | |
206 | - Implement table unique constraints. | |
207 | - Support cooperative locking between callers. | |
208 | - ovs-dpctl: | |
209 | - New "-s" option for "show" command prints packet and byte | |
210 | counters for each port. | |
211 | - ovs-ofctl: | |
212 | - New "--readd" option for "replace-flows". | |
213 | - ovs-vsctl: | |
214 | - New "show" command to print an overview of configuration. | |
215 | - New "comment" command to add remark that explains intentions. | |
216 | - ovs-brcompatd has been rewritten to fix long-standing bugs. | |
217 | - ovs-openflowd has been renamed test-openflowd and moved into the | |
218 | tests directory. Its presence confused too many users. Please | |
219 | use ovs-vswitchd instead. | |
220 | - New ovs-benchmark utility to test flow setup performance. | |
221 | - A new log level "off" has been added. Configuring a log facility | |
222 | "off" prevents any messages from being logged to it. Previously, | |
223 | "emer" was effectively "off" because no messages were ever logged at | |
224 | level "emer". Now, errors that cause a process to exit are logged | |
225 | at "emer" level. | |
226 | - "configure" option --with-l26 has been renamed --with-linux, and | |
227 | --with-l26-source has been renamed --with-linux-source. The old | |
228 | names will be removed after the next release, so please update | |
229 | your scripts. | |
230 | - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and | |
231 | datapath/linux-2.6/compat-2.6 directories. | |
232 | - Feature removals: | |
233 | - Dropped support for "tun_id_from_cookie" OpenFlow extension. | |
234 | Please use the extensible match extensions instead. | |
235 | - Removed the Maintenance_Point and Monitor tables in an effort | |
236 | to simplify 802.1ag configuration. | |
237 | - Performance and scalability improvements | |
238 | - Bug fixes | |
239 | ||

279 | bugs. New ovs-vlan-bug-workaround command for enabling and | |
280 | disabling a workaround for these driver bugs. | |
281 | - OpenFlow support: | |
282 | - "Resubmit" actions now update flow statistics. | |
283 | - New "register" extension for use in matching and actions, via NXM. | |
284 | - New "multipath" experimental action extension. | |
285 | - New support for matching multicast Ethernet frames, via NXM. | |
286 | - New extension for OpenFlow vendor error codes. | |
287 | - New extension to set the QoS output queue without actually | |
288 | sending to an output port. | |
289 | - Open vSwitch now reports a single flow table, instead of | |
290 | separate hash and wildcard tables. This better models the | |
291 | current implementation. | |
292 | - New experimental "note" action. | |
293 | - New "ofproto/trace" ovs-appctl command and associated utilities | |
294 | to ease debugging complex flow tables. | |
295 | - Database: | |
296 | - Schema documentation now includes an entity-relationship diagram. | |
297 | - The database is now garbage collected. In most tables, | |
298 | unreferenced rows will be deleted automatically. | |
299 | - Many tables now include statistics updated periodically by | |
300 | ovs-vswitchd or ovsdb-server. | |
301 | - Every table now has an "external-ids" column for use by OVS | |
302 | integrators. | |
303 | - There is no default controller anymore. Each bridge must have its | |
304 | controller individually specified. | |
