1 | post-v1.8.0 |
2 | ------------------------ | |
f6eb6b20 GL |
3 | - FreeBSD is now a supported platform, thanks to code contributions from |
4 | Gaetano Catalli, Ed Maste, and Giuseppe Lettieri. | |
b592e726 | 5 | - ovs-bugtool: New --ovs option to report only OVS related information. |
781dee08 BP |
6 | - New %t and %T log escapes to identify the subprogram within a |
7 | cooperating group of processes or threads that emitted a log message. | |
8 | The default log patterns now include this information. | |
32455024 | 9 | - OpenFlow: |
e878338b SH |
10 | - Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL |
11 | fields in IPv6 neighbor discovery messages, and IPv6 flow label. | |
2562714a | 12 | - ovs-dpctl: |
4b3b8d8f JP |
13 | - Support requesting the port number with the "port_no" option in |
14 | the "add-if" command. | |
2562714a BP |
15 | - ovs-pki: The "online PKI" features have been removed, along with |
16 | the ovs-pki-cgi program that facilitated it, because of some | |
17 | alarmist insecurity claims. We do not believe that these claims | |
18 | are true, but because we do not know of any users for this | |
19 | feature it seems better on balance to remove it. (The ovs-pki-cgi | |
20 | program was not included in distribution packaging.) | |
f6af6c0e EJ |
21 | - Stable bond mode is deprecated and will be removed no earlier than |
22 | February 2013. Please email dev@openvswitch.org with concerns. | |
c51c638a EJ |
23 | - The autopath action is deprecated and will be removed no earlier than |
24 | February 2013. Please email dev@openvswitch.org with concerns. | |
0faed346 EJ |
25 | - The null interface type is deprecated and will be removed no earlier |
26 | than February 2013. Please email dev@openvswitch.org with concerns. | |

f25d0cf3 BP |
32 | - Authors of controllers, please read the new section titled "Action |
33 | Reproduction" in DESIGN, which describes an Open vSwitch change in | |
34 | behavior in corner cases that may affect some controllers. | |
2d8bdd8f AA |
35 | - ovs-l3ping: |
36 | - A new test utility that can create L3 tunnel between two Open | |

ff0b06ee BP |
42 | - Allow general bitwise masking for IPv4 and IPv6 addresses in |
43 | IPv4, IPv6, and ARP packets. (Previously, only CIDR masks | |
c08201d6 BP |
44 | were allowed.) |
45 | - Allow support for arbitrary Ethernet masks. (Previously, only | |
46 | the multicast bit in the destination address could be individually | |
47 | masked.) | |
969fc56c | 48 | - New field OXM_OF_METADATA, to align with OpenFlow 1.1. |
0414d158 BP |
49 | - The OFPST_QUEUE request now reports an error if a specified port or |
50 | queue does not exist, or for requests for a specific queue on all | |
51 | ports, if the specified queue does not exist on any port. (Previous | |
52 | versions generally reported an empty set of results.) | |
2b07c8b1 BP |
53 | - New "flow monitor" feature to allow controllers to be notified of |
54 | flow table changes as they happen. | |
c93f9a78 EJ |
55 | - Additional protocols are not mirrored and dropped when forward-bpdu is |
56 | false. For a full list, see the ovs-vswitchd.conf.db man page. | |
38f7147c EJ |
57 | - Open vSwitch now sends RARP packets in situations where it previously |
58 | sent a custom protocol, making it consistent with behavior of QEMU and | |
59 | VMware. | |
969e46a2 AS |
60 | - All Open vSwitch programs and log files now show timestamps in UTC, |
61 | instead the local timezone, by default. | |

98 | *** Internal only release *** | |
4df08875 | 99 | - bonding |
bdebeece EJ |
100 | - LACP bonds no longer fall back to balance-slb when negotiations fail. |
101 | Instead they drop traffic. | |
4df08875 EJ |
102 | - The default bond_mode changed from SLB to active-backup, to protect |
103 | unsuspecting users from the significant risks of SLB bonds (which are | |
104 | documented in vswitchd/INTERNALS). | |
bc1b010c EJ |
105 | - Load balancing can be disabled by setting the bond-rebalance-interval |
106 | to zero. | |
73f33563 BP |
107 | - OpenFlow: |
108 | - Added support for bitwise matching on TCP and UDP ports. | |
109 | See ovs-ofctl(8) for more information. | |
80d5aefd BP |
110 | - NXM flow dumps now include times elapsed toward idle and hard |
111 | timeouts. | |
112 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |

118 | over output to OFPP_CONTROLLER. | |
2c999774 BP |
119 | - When QoS settings for an interface do not configure a default queue |
120 | (queue 0), Open vSwitch now uses a default configuration for that | |
121 | queue, instead of dropping all packets as in previous versions. | |
2a3e30b2 BP |
122 | - Logging: |
123 | - Logging to console and file will have UTC timestamp as a default for | |
124 | all the daemons. An example of the default format is | |

126 | format as before. | |
127 | - The syntax of commands and options to set log levels was simplified, | |
128 | to make it easier to remember. | |
254750ce BP |
129 | - New support for limiting the number of flows in an OpenFlow flow |
130 | table, with configurable policy for evicting flows upon | |
131 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
132 | for more information. | |
9886b662 BP |
133 | - New "enable-async-messages" column in the Controller table. If set to |
134 | false, OpenFlow connections to the controller will initially have all | |
135 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
1745cd08 BP |
136 | - ofproto-provider interface: |
137 | - "struct rule" has a new member "used" that ofproto implementations | |
138 | should maintain by updating with ofproto_rule_update_used(). | |
8f46c9bb BP |
139 | - ovsdb-client: |
140 | - The new option --timestamp causes the "monitor" command to print | |
141 | a timestamp with every update. | |
a7aa2d3c | 142 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. |
d0a8c2e0 JP |

158 | directories as defaults. | |
d1add61d JP |
159 | - The default MAC learning timeout has been increased from 60 seconds |
160 | to 300 seconds. The MAC learning timeout is now configurable. | |

52a90c29 BP |
166 | - New "VLAN splinters" feature to work around buggy device drivers |
167 | in old Linux versions. (This feature is deprecated. When | |
168 | broken device drivers are no longer in widespread use, we will | |
169 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
170 | information. | |

9d24de3b | 177 | - ovs-vswitchd: |
c06bba01 JP |
178 | - Don't require the "normal" action to use mirrors. Traffic will |
179 | now be properly mirrored for any flows, regardless of their | |
180 | actions. | |
9d24de3b | 181 | - Track packet and byte statistics sent on mirrors. |
733adf2a LG |
182 | - The sFlow implementation can now usually infer the correct agent |
183 | device instead of having to be told explicitly. | |

4c57c3bc EJ |
191 | - bonding: |
192 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
193 | to active-backup. SLB bonds carry significant risks with them | |
194 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
195 | users from running into. Users are advised to update any scripts or | |
196 | configuration which may be negatively impacted by explicitly setting | |
197 | the bond mode which they want to use. | |
b6a9a95b | 198 | |

217 | of just one. By default, only table 0 is consulted, but the | |
218 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
219 | tables. Tables 128 and above are reserved for use by the | |
220 | switch itself; please use only tables 0 through 127. | |

229 | fragment handling policy. | |
2f4bc10d BP |
230 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. |
231 | By default it remains compatible with the old version and other | |
c87112ca | 232 | standards-based implementations. |
17411ecf JG |
233 | - Flow setups are now processed in a round-robin manner across ports |
234 | to prevent any single client from monopolizing the CPU and conducting | |
235 | a denial of service attack. | |
ecac4ebf BP |
236 | - Added support for native VLAN tagging. A new "vlan_mode" |
237 | parameter can be set for "port". Possible values: "access", | |

263 | use ovs-vswitchd instead. | |
1a142ced JP |
264 | - New ovs-benchmark utility to test flow setup performance. |
265 | - A new log level "off" has been added. Configuring a log facility | |
266 | "off" prevents any messages from being logged to it. Previously, | |
267 | "emer" was effectively "off" because no messages were ever logged at | |
268 | level "emer". Now, errors that cause a process to exit are logged | |
269 | at "emer" level. | |
8a2d6596 BP |
270 | - "configure" option --with-l26 has been renamed --with-linux, and |
271 | --with-l26-source has been renamed --with-linux-source. The old | |

313 | - New "find" command. | |
314 | - ovs-ofctl: | |
315 | - New "queue-stats" command for printing queue stats. | |
316 | - New commands "replace-flows" and "diff-flows". | |
317 | - Commands to add and remove flows can now read from files. | |

331 | - New extension to set the QoS output queue without actually | |
332 | sending to an output port. | |
333 | - Open vSwitch now reports a single flow table, instead of | |
334 | separate hash and wildcard tables. This better models the | |
335 | current implementation. | |
336 | - New experimental "note" action. | |
337 | - New "ofproto/trace" ovs-appctl command and associated utilities | |
338 | to ease debugging complex flow tables. | |
339 | - Database: | |
