-post-v1.9.0
---------------------
+v2.0.0 - 15 Oct 2013
+---------------------
+ - The ovs-vswitchd process is no longer single-threaded. Multiple
+ threads are now used to handle flow set up and asynchronous
+ logging.
+ - OpenFlow:
+ * Experimental support for OpenFlow 1.1 (in addition to 1.2 and
+ 1.3, which had experimental support in 1.10).
+ * New support for matching outer source and destination IP address
+ of tunneled packets, for tunnel ports configured with the newly
+ added "remote_ip=flow" and "local_ip=flow" options.
+ * Support for matching on metadata 'pkt_mark' for interacting with
+ other system components. On Linux this corresponds to the skb
+ mark.
+ * Support matching, rewriting SCTP ports
+ - The Interface table in the database has a new "ifindex" column to
+ report the interface's OS-assigned ifindex.
+ - New "check-oftest" Makefile target for running OFTest against Open
+ vSwitch. See README-OFTest for details.
+ - The flow eviction threshold has been moved to the Open_vSwitch table.
+ - Database names are now mandatory when specifying ovsdb-server options
+ through database paths (e.g. Private key option with the database name
+ should look like "--private-key=db:Open_vSwitch,SSL,private_key").
+ - Added ovs-dev.py, a utility script helpful for Open vSwitch developers.
+ - Support for Linux kernels up to 3.10
+ - ovs-ofctl:
+ * New "ofp-parse" for printing OpenFlow messages read from a file.
+ - Added configurable flow caching support to IPFIX exporter.
+ - Dropped support for Linux pre-2.6.32.
+ - Log file timestamps and ovsdb commit timestamps are now reported
+ with millisecond resolution. (Previous versions only reported
+ whole seconds.)
-v1.9.0 - xx xxx xxxx
---------------------
- - The tunneling code no longer assumes input and output keys are symmetric.
- If they are not, PMTUD needs to be disabled for tunneling to work. Note
- this only applies to flow-based keys.
+v1.11.0 - 28 Aug 2013
+---------------------
+ - Support for megaflows, which allows wildcarding in the kernel (and
+ any dpif implementation that supports wildcards). Depending on
+ the flow table and switch configuration, flow set up rates are
+ close to the Linux bridge.
+ - The "tutorial" directory contains a new tutorial for some advanced
+ Open vSwitch features.
+ - Stable bond mode has been removed.
+ - The autopath action has been removed.
+ - New support for the data encapsulation format of the LISP tunnel
+ protocol (RFC 6830). An external control plane or manual flow
+ setup is required for EID-to-RLOC mapping.
+ - OpenFlow:
+ * The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow
+ 1.1 and later are now implemented.
+ * New "stack" extension for use in actions, to push and pop from
+ NXM fields.
+ * The "load" and "set_field" actions can now modify the "in_port". (This
+ allows one to enable output to a flow's input port by setting the
+ in_port to some unused value, such as OFPP_NONE.)
+ - ovs-dpctl:
+ * New debugging commands "add-flow", "mod-flow", "del-flow".
+ * "dump-flows" now has a -m option to increase output verbosity.
+ - In dpif-based bridges, cache action translations, which can improve
+ flow set up performance by 80% with a complicated flow table.
+ - New syslog format, prefixed with "ovs|", to be easier to filter.
+ - RHEL: Removes the default firewall rule that allowed GRE traffic to
+ pass through. Any users that relied on this automatic firewall hole
+ will have to manually configure it. The ovs-ctl(8) manpage documents
+ the "enable-protocol" command that can be used as an alternative.
+ - New CFM demand mode which uses data traffic to indicate interface
+ liveness.
+
+v1.10.0 - 01 May 2013
+---------------------
+ - Bridge compatibility support has been removed. Any uses that
+ rely on ovs-brcompatd will have to stick with Open vSwitch 1.9.x
+ or adapt to native Open vSwitch support (e.g. use ovs-vsctl instead
+ of brctl).
+ - The maximum size of the MAC learning table is now configurable.
+ - With the Linux datapath, packets for new flows are now queued
+ separately on a per-port basis, so it should no longer be
+ possible for a large number of new flows arriving on one port to
+ prevent new flows from being processed on other ports.
+ - ovs-vsctl:
+ * Previously ovs-vsctl would retry connecting to the database forever,
+ causing it to hang if ovsdb-server was not running. Now, ovs-vsctl
+ only tries once by default (use --retry to try forever). This change
+ means that you may want to remove uses of --timeout to avoid hangs
+ in ovs-vsctl calls.
+ * Many "ovs-vsctl" database commands now accept an --if-exists option.
+ Please refer to the ovs-vsctl manpage for details.
+ - OpenFlow:
+ - Experimental support for newer versions of OpenFlow. See
+ the "What versions of OpenFlow does Open vSwitch support?"
+ question in the FAQ for more details.
+ - The OpenFlow "dp_desc" may now be configured by setting the
+ value of other-config:dp-desc in the Bridge table.
+ - It is possible to request the OpenFlow port number with the
+ "ofport_request" column in the Interface table.
+ - The NXM flow_removed message now reports the OpenFlow table ID
+ from which the flow was removed.
+ - Tunneling:
+ - New support for the VXLAN tunnel protocol (see the IETF draft here:
+ http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03).
+ - Tunneling requires the version of the kernel module paired with
+ Open vSwitch 1.9.0 or later.
+ - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit)
+ is no longer supported.
+ - Path MTU discovery is no longer supported.
+ - CAPWAP tunneling support removed.
+ - Tunnels with multicast destination ports are no longer supported.
+ - ovs-dpctl:
+ - The "dump-flows" and "del-flows" no longer require an argument
+ if only one datapath exists.
+ - ovs-appctl:
+ - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit"
+ commands available allow control over logging rate limits.
+ - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command
+ that mimic the equivalent ovs-dpctl commands.
+ - The ofproto library is now responsible for assigning OpenFlow port
+ numbers. An ofproto implementation should assign them when
+ port_construct() is called.
+ - All dpif-based bridges of a particular type share a common
+ datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl
+ commands will now return information on that shared datapath. To
+ get the equivalent bridge-specific information, use the new
+ "ovs-appctl dpif/*" commands.
+ - Backward-incompatible changes:
+ - Earlier Open vSwitch versions treated ANY as a wildcard in flow
+ syntax. OpenFlow 1.1 adds a port named ANY, which introduces a
+ conflict. ANY was rarely used in flow syntax, so we chose to
+ retire that meaning of ANY in favor of the OpenFlow 1.1 meaning.
+ - Patch ports no longer require kernel support, so they now work
+ with FreeBSD and the kernel module built into Linux 3.3 and later.
+ - New "sample" action.
+
+
+v1.9.0 - 26 Feb 2013
+------------------------
+ - Datapath:
+ - Support for ipv6 set action.
+ - SKB mark matching and setting.
+ - support for Linux kernels up to 3.8
- FreeBSD is now a supported platform, thanks to code contributions from
Gaetano Catalli, Ed Maste, and Giuseppe Lettieri.
- ovs-bugtool: New --ovs option to report only OVS related information.
- Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL
fields in IPv6 neighbor discovery messages, and IPv6 flow label.
- Adds support for writing to the metadata field for a flow.
- - It is possible to request the OpenFlow port number with the
- "ofport_request" column in the Interface table.
+ - Tunneling:
+ - The tunneling code no longer assumes input and output keys are
+ symmetric. If they are not, PMTUD needs to be disabled for
+ tunneling to work. Note this only applies to flow-based keys.
+ - New support for a nonstandard form of GRE that supports a 64-bit key.
+ - Tunnel Path MTU Discovery default value was set to 'disabled'.
+ This feature is deprecated and will be removed soon.
+ - Tunnel header caching removed.
- ovs-ofctl:
- Commands and actions that accept port numbers now also accept keywords
that represent those ports (such as LOCAL, NONE, and ALL). This is
are true, but because we do not know of any users for this
feature it seems better on balance to remove it. (The ovs-pki-cgi
program was not included in distribution packaging.)
- - Tunnel Path MTU Discovery default value was set to 'disabled'. This
- feature is deprecated and will be removed soon.
- ovsdb-server now enforces the immutability of immutable columns. This
was not enforced in earlier versions due to an oversight.
- - New support for a nonstandard form of GRE that supports a 64-bit key.
- - The ofproto library is now responsible for assigning OpenFlow port
- numbers. An ofproto implementation should assign them when
- port_construct() is called.
- The following features are now deprecated. They will be removed no
earlier than February 2013. Please email dev@openvswitch.org with
concerns.
+ - Bridge compatibility.
- Stable bond mode.
- The autopath action.
- Interface type "null".
- Numeric values for reserved ports (see "ovs-ofctl" note above).
- Tunnel Path MTU Discovery.
+ - CAPWAP tunnel support.
+ - The data in the RARP packets can now be matched in the same way as the
+ data in ARP packets.
