-post-v1.3.0
+post-v1.8.0
------------------------
+ - ovs-bugtool: New --ovs option to report only OVS related information.
+ - New %t and %T log escapes to identify the subprogram within a
+ cooperating group of processes or threads that emitted a log message.
+ The default log patterns now include this information.
+ - OpenFlow:
+ - Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL
+ fields in IPv6 neighbor discovery messages, and IPv6 flow label.
+
+
+v1.8.0 - xx xxx xxxx
+------------------------
+ - New FAQ. Please send updates and additions!
+ - Authors of controllers, please read the new section titled "Action
+ Reproduction" in DESIGN, which describes an Open vSwitch change in
+ behavior in corner cases that may affect some controllers.
+ - ovs-l3ping:
+ - A new test utility that can create L3 tunnel between two Open
+ vSwitches and detect connectivity issues.
+ - ovs-ofctl:
+ - New --sort and --rsort options for "dump-flows" command.
+ - "mod-port" command can now control all OpenFlow config flags.
+ - OpenFlow:
+ - Allow general bitwise masking for IPv4 and IPv6 addresses in
+ IPv4, IPv6, and ARP packets. (Previously, only CIDR masks
+ were allowed.)
+ - Allow support for arbitrary Ethernet masks. (Previously, only
+ the multicast bit in the destination address could be individually
+ masked.)
+ - New field OXM_OF_METADATA, to align with OpenFlow 1.1.
+ - The OFPST_QUEUE request now reports an error if a specified port or
+ queue does not exist, or for requests for a specific queue on all
+ ports, if the specified queue does not exist on any port. (Previous
+ versions generally reported an empty set of results.)
+ - New "flow monitor" feature to allow controllers to be notified of
+ flow table changes as they happen.
+ - Additional protocols are not mirrored and dropped when forward-bpdu is
+ false. For a full list, see the ovs-vswitchd.conf.db man page.
+ - Open vSwitch now sends RARP packets in situations where it previously
+ sent a custom protocol, making it consistent with behavior of QEMU and
+ VMware.
+ - All Open vSwitch programs and log files now show timestamps in UTC,
+ instead the local timezone, by default.
+
+
+v1.7.0 - xx xxx xxxx
+------------------------
+ - kernel modules are renamed. openvswitch_mod.ko is now
+ openvswitch.ko and brcompat_mod.ko is now brcompat.ko.
+ - Increased the number of NXM registers to 8.
+ - Added ability to configure dscp setting for manager and controller
+ connections. By default, these connections have a DSCP value of
+ Internetwork Control (0xc0).
+ - Added the granular link health statistics, 'cfm_health', to an
+ interface.
+ - OpenFlow:
+ - Added support to mask nd_target for ICMPv6 neighbor discovery flows.
+ - Added support for OpenFlow 1.3 port description (OFPMP_PORT_DESC)
+ multipart messages.
+ - ovs-ofctl:
+ - Added the "dump-ports-desc" command to retrieve port
+ information using the new port description multipart messages.
+ - ovs-test:
+ - Added support for spawning ovs-test server from the client.
+ - Now ovs-test is able to automatically create test bridges and ports.
+ - "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows.
+ - The "coverage/log" command previously available through ovs-appctl
+ has been replaced by "coverage/show". The new command replies with
+ coverage counter values, instead of logging them.
+
+
+v1.6.1 - 25 Jun 2012
+------------------------
+ - Allow OFPP_CONTROLLER as the in_port for packet-out messages.
+
+
+v1.6.0 - 24 Feb 2012
+------------------------
+ *** Internal only release ***
+ - bonding
+ - LACP bonds no longer fall back to balance-slb when negotiations fail.
+ Instead they drop traffic.
+ - The default bond_mode changed from SLB to active-backup, to protect
+ unsuspecting users from the significant risks of SLB bonds (which are
+ documented in vswitchd/INTERNALS).
+ - Load balancing can be disabled by setting the bond-rebalance-interval
+ to zero.
+ - OpenFlow:
+ - Added support for bitwise matching on TCP and UDP ports.
+ See ovs-ofctl(8) for more information.
+ - NXM flow dumps now include times elapsed toward idle and hard
+ timeouts.
+ - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows
+ controllers more precise control over which OpenFlow messages they
+ receive asynchronously.
+ - New "fin_timeout" action.
+ - Added "fin_timeout" support to "learn" action.
+ - New Nicira action NXAST_CONTROLLER that offers additional features
+ over output to OFPP_CONTROLLER.
+ - When QoS settings for an interface do not configure a default queue
+ (queue 0), Open vSwitch now uses a default configuration for that
+ queue, instead of dropping all packets as in previous versions.
+ - Logging:
+ - Logging to console and file will have UTC timestamp as a default for
+ all the daemons. An example of the default format is
+ 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default
+ format as before.
+ - The syntax of commands and options to set log levels was simplified,
+ to make it easier to remember.
+ - New support for limiting the number of flows in an OpenFlow flow
+ table, with configurable policy for evicting flows upon
+ overflow. See the Flow_Table table in ovs-vswitch.conf.db(5)
+ for more information.
+ - New "enable-async-messages" column in the Controller table. If set to
+ false, OpenFlow connections to the controller will initially have all
+ asynchronous messages disabled, overriding normal OpenFlow behavior.
+ - ofproto-provider interface:
+ - "struct rule" has a new member "used" that ofproto implementations
+ should maintain by updating with ofproto_rule_update_used().
+ - ovsdb-client:
+ - The new option --timestamp causes the "monitor" command to print
+ a timestamp with every update.
+ - CFM module CCM broadcasts can now be tagged with an 802.1p priority.
+
+
+v1.5.0 - 01 Jun 2012
+------------------------
+ - OpenFlow:
+ - Added support for querying, modifying, and deleting flows
+ based on flow cookie when using NXM.
+ - Added new NXM_PACKET_IN format.
+ - Added new NXAST_DEC_TTL action.
+ - ovs-ofctl:
+ - Added daemonization support to the monitor and snoop commands.
+ - ovs-vsctl:
+ - The "find" command supports new set relational operators
+ {=}, {!=}, {<}, {>}, {<=}, and {>=}.
+ - ovsdb-tool now uses the typical database and schema installation
+ directories as defaults.
+ - The default MAC learning timeout has been increased from 60 seconds
+ to 300 seconds. The MAC learning timeout is now configurable.
+
+
+v1.4.0 - 30 Jan 2012
+------------------------
+ - Compatible with Open vSwitch kernel module included in Linux 3.3.
+ - New "VLAN splinters" feature to work around buggy device drivers
+ in old Linux versions. (This feature is deprecated. When
+ broken device drivers are no longer in widespread use, we will
+ delete this feature.) See ovs-vswitchd.conf.db(5) for more
+ information.
- OpenFlow:
- Added ability to match on IPv6 flow label through NXM.
+ - Added ability to match on ECN bits in IPv4 and IPv6 through NXM.
+ - Added ability to match on TTL in IPv4 and IPv6 through NXM.
+ - Added ability to modify ECN bits in IPv4.
+ - Added ability to modify TTL in IPv4.
+ - ovs-vswitchd:
+ - Don't require the "normal" action to use mirrors. Traffic will
+ now be properly mirrored for any flows, regardless of their
+ actions.
+ - Track packet and byte statistics sent on mirrors.
+ - The sFlow implementation can now usually infer the correct agent
+ device instead of having to be told explicitly.
- ovs-appctl:
- New "fdb/flush" command to flush bridge's MAC learning table.
+ - ovs-test:
+ - A new distributed testing tool that allows one to diagnose performance
+ and connectivity issues. This tool currently is not included in RH or
+ Xen packages.
+ - RHEL packaging now supports integration with Red Hat network scripts.
+ - bonding:
+ - Post 1.4.*, OVS will be changing the default bond mode from balance-slb
+ to active-backup. SLB bonds carry significant risks with them
+ (documented vswitchd/INTERNALS) which we want to prevent unsuspecting
+ users from running into. Users are advised to update any scripts or
+ configuration which may be negatively impacted by explicitly setting
+ the bond mode which they want to use.

- New ovs-ofctl "get-frags" and "set-frags" commands to get and set
fragment handling policy.
- - CAPWAP tunneling now supports an extension to transport a 64-key. By

+ - CAPWAP tunneling now supports an extension to transport a 64-bit key.
+ By default it remains compatible with the old version and other
standards-based implementations.
- Flow setups are now processed in a round-robin manner across ports
to prevent any single client from monopolizing the CPU and conducting
datapath/linux-2.6/compat-2.6 directories.
- Feature removals:
- Dropped support for "tun_id_from_cookie" OpenFlow extension.
- Please use the extensible match extensions instead.
