2 | ------------------------ | |
c483d489 | 3 | - New FAQ. Please send updates and additions! |
f25d0cf3 BP |
4 | - Authors of controllers, please read the new section titled "Action |
5 | Reproduction" in DESIGN, which describes an Open vSwitch change in | |
6 | behavior in corner cases that may affect some controllers. | |
2d8bdd8f AA |
7 | - ovs-l3ping: |
8 | - A new test utility that can create L3 tunnel between two Open | |
9 | vSwitches and detect connectivity issues. | |
5498c01f | 10 | - ovs-ofctl: |
bdcc5925 | 11 | - New --sort and --rsort options for "dump-flows" command. |
5498c01f | 12 | - "mod-port" command can now control all OpenFlow config flags. |
c08201d6 | 13 | - OpenFlow: |
ff0b06ee BP |
14 | - Allow general bitwise masking for IPv4 and IPv6 addresses in |
15 | IPv4, IPv6, and ARP packets. (Previously, only CIDR masks | |
c08201d6 BP |
16 | were allowed.) |
17 | - Allow support for arbitrary Ethernet masks. (Previously, only | |
18 | the multicast bit in the destination address could be individually | |
19 | masked.) | |
969fc56c | 20 | - New field OXM_OF_METADATA, to align with OpenFlow 1.1. |
0414d158 BP |
21 | - The OFPST_QUEUE request now reports an error if a specified port or |
22 | queue does not exist, or for requests for a specific queue on all | |
23 | ports, if the specified queue does not exist on any port. (Previous | |
24 | versions generally reported an empty set of results.) | |
2b07c8b1 BP |
25 | - New "flow monitor" feature to allow controllers to be notified of |
26 | flow table changes as they happen. | |
c93f9a78 EJ |
27 | - Additional protocols are not mirrored and dropped when forward-bpdu is |
28 | false. For a full list, see the ovs-vswitchd.conf.db man page. | |
38f7147c EJ |
29 | - Open vSwitch now sends RARP packets in situations where it previously |
30 | sent a custom protocol, making it consistent with behavior of QEMU and | |
31 | VMware. | |
969e46a2 AS |
32 | - All Open vSwitch programs and log files now show timestamps in UTC, |
33 | instead the local timezone, by default. | |
c8d5d22c JP |

39 | openvswitch.ko and brcompat_mod.ko is now brcompat.ko. | |
e9358af6 | 40 | - Increased the number of NXM registers to 8. |
f125905c MM |
41 | - Added ability to configure dscp setting for manager and controller |
42 | connections. By default, these connections have a DSCP value of | |
43 | Internetwork Control (0xc0). | |

51 | - Added the "dump-ports-desc" command to retrieve port | |
52 | information using the new port description multipart messages. | |
8d25d9a2 AA |
53 | - ovs-test: |
54 | - Added support for spawning ovs-test server from the client. | |
55 | - Now ovs-test is able to automatically create test bridges and ports. | |
7393104d | 56 | - "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows. |
a5f607bc BP |
57 | - The "coverage/log" command previously available through ovs-appctl |
58 | has been replaced by "coverage/show". The new command replies with | |
59 | coverage counter values, instead of logging them. | |

68 | ------------------------ | |
69 | *** Internal only release *** | |
4df08875 | 70 | - bonding |
bdebeece EJ |
71 | - LACP bonds no longer fall back to balance-slb when negotiations fail. |
72 | Instead they drop traffic. | |
4df08875 EJ |
73 | - The default bond_mode changed from SLB to active-backup, to protect |
74 | unsuspecting users from the significant risks of SLB bonds (which are | |
75 | documented in vswitchd/INTERNALS). | |
bc1b010c EJ |
76 | - Load balancing can be disabled by setting the bond-rebalance-interval |
77 | to zero. | |
73f33563 BP |
78 | - OpenFlow: |
79 | - Added support for bitwise matching on TCP and UDP ports. | |
80 | See ovs-ofctl(8) for more information. | |
80d5aefd BP |
81 | - NXM flow dumps now include times elapsed toward idle and hard |
82 | timeouts. | |
83 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |
84 | controllers more precise control over which OpenFlow messages they | |
85 | receive asynchronously. | |
0e553d9c BP |
86 | - New "fin_timeout" action. |
87 | - Added "fin_timeout" support to "learn" action. | |

88 | - New Nicira action NXAST_CONTROLLER that offers additional features |
89 | over output to OFPP_CONTROLLER. | |
2c999774 BP |
90 | - When QoS settings for an interface do not configure a default queue |
91 | (queue 0), Open vSwitch now uses a default configuration for that | |
92 | queue, instead of dropping all packets as in previous versions. | |
2a3e30b2 BP |
93 | - Logging: |
94 | - Logging to console and file will have UTC timestamp as a default for | |
95 | all the daemons. An example of the default format is | |
96 | 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default | |
97 | format as before. | |
98 | - The syntax of commands and options to set log levels was simplified, | |
99 | to make it easier to remember. | |
254750ce BP |
100 | - New support for limiting the number of flows in an OpenFlow flow |
101 | table, with configurable policy for evicting flows upon | |
102 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
103 | for more information. | |
9886b662 BP |
104 | - New "enable-async-messages" column in the Controller table. If set to |
105 | false, OpenFlow connections to the controller will initially have all | |
106 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
1745cd08 BP |
107 | - ofproto-provider interface: |
108 | - "struct rule" has a new member "used" that ofproto implementations | |
109 | should maintain by updating with ofproto_rule_update_used(). | |
8f46c9bb BP |
110 | - ovsdb-client: |
111 | - The new option --timestamp causes the "monitor" command to print | |
112 | a timestamp with every update. | |
a7aa2d3c | 113 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. |
d0a8c2e0 JP |

129 | directories as defaults. | |
d1add61d JP |
130 | - The default MAC learning timeout has been increased from 60 seconds |
131 | to 300 seconds. The MAC learning timeout is now configurable. | |
e68bfcfc JP |
132 | |
133 | ||
ef13dc11 | 134 | v1.4.0 - 30 Jan 2012 |
b6a9a95b | 135 | ------------------------ |

52a90c29 BP |
137 | - New "VLAN splinters" feature to work around buggy device drivers |
138 | in old Linux versions. (This feature is deprecated. When | |
139 | broken device drivers are no longer in widespread use, we will | |
140 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
141 | information. | |
fa8223b7 JP |
142 | - OpenFlow: |
143 | - Added ability to match on IPv6 flow label through NXM. | |

9d24de3b | 148 | - ovs-vswitchd: |
c06bba01 JP |
149 | - Don't require the "normal" action to use mirrors. Traffic will |
150 | now be properly mirrored for any flows, regardless of their | |
151 | actions. | |
9d24de3b | 152 | - Track packet and byte statistics sent on mirrors. |
733adf2a LG |
153 | - The sFlow implementation can now usually infer the correct agent |
154 | device instead of having to be told explicitly. | |
f0a3aa2e AA |
155 | - ovs-appctl: |
156 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
0be6140a AA |

159 | and connectivity issues. This tool currently is not included in RH or | |
160 | Xen packages. | |
0fb42626 | 161 | - RHEL packaging now supports integration with Red Hat network scripts. |
4c57c3bc EJ |
162 | - bonding: |
163 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
164 | to active-backup. SLB bonds carry significant risks with them | |
165 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
166 | users from running into. Users are advised to update any scripts or | |
167 | configuration which may be negatively impacted by explicitly setting | |
168 | the bond mode which they want to use. | |
b6a9a95b | 169 | |

29901626 BP |
186 | - ovs-vswitchd: |
187 | - The software switch now supports 255 OpenFlow tables, instead | |
188 | of just one. By default, only table 0 is consulted, but the | |
189 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
190 | tables. Tables 128 and above are reserved for use by the | |
191 | switch itself; please use only tables 0 through 127. | |
21f7563c | 192 | - Add support for 802.1D spanning tree (STP). |
7257b535 BP |
193 | - Fragment handling extensions: |

198 | via "ip_frag" in ovs-ofctl). | |
199 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
200 | fragment handling policy. | |
2f4bc10d BP |
201 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. |
202 | By default it remains compatible with the old version and other | |
c87112ca | 203 | standards-based implementations. |
17411ecf JG |
204 | - Flow setups are now processed in a round-robin manner across ports |
205 | to prevent any single client from monopolizing the CPU and conducting | |
206 | a denial of service attack. | |
ecac4ebf BP |
207 | - Added support for native VLAN tagging. A new "vlan_mode" |
208 | parameter can be set for "port". Possible values: "access", | |
209 | "trunk", "native-tagged" and "native-untagged". | |
023e1e0a | 210 | - test-openflowd has been removed. Please use ovs-vswitchd instead. |
3e60856b | 211 | |
5e9c5b61 | 212 | v1.2.0 - 03 Aug 2011 |

234 | use ovs-vswitchd instead. | |
1a142ced JP |
235 | - New ovs-benchmark utility to test flow setup performance. |
236 | - A new log level "off" has been added. Configuring a log facility | |
237 | "off" prevents any messages from being logged to it. Previously, | |
238 | "emer" was effectively "off" because no messages were ever logged at | |
239 | level "emer". Now, errors that cause a process to exit are logged | |
240 | at "emer" level. | |
8a2d6596 BP |
241 | - "configure" option --with-l26 has been renamed --with-linux, and |
242 | --with-l26-source has been renamed --with-linux-source. The old | |

244 | your scripts. | |
22bcc0e7 JG |
245 | - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and |
246 | datapath/linux-2.6/compat-2.6 directories. | |

248 | - Dropped support for "tun_id_from_cookie" OpenFlow extension. | |
0be6140a | 249 | Please use the extensible match extensions instead. |
93b8df38 EJ |
250 | - Removed the Maintenance_Point and Monitor tables in an effort |
251 | to simplify 802.1ag configuration. | |
1a142ced JP |
252 | - Performance and scalability improvements |

284 | - New "find" command. | |
285 | - ovs-ofctl: | |
286 | - New "queue-stats" command for printing queue stats. | |
287 | - New commands "replace-flows" and "diff-flows". | |
288 | - Commands to add and remove flows can now read from files. | |

302 | - New extension to set the QoS output queue without actually | |
303 | sending to an output port. | |
304 | - Open vSwitch now reports a single flow table, instead of | |
305 | separate hash and wildcard tables. This better models the | |
306 | current implementation. | |
307 | - New experimental "note" action. | |
308 | - New "ofproto/trace" ovs-appctl command and associated utilities | |
309 | to ease debugging complex flow tables. | |
310 | - Database: | |
311 | - Schema documentation now includes an entity-relationship diagram. | |
