-v1.10.0 - xx xxx xxxx
+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".
+ - 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
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.
- - Many "ovs-vsctl" database commands now accept an --if-exists option.
- Please refer to the ovs-vsctl manpage for details.
+ - 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?"
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-02).
+ 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.
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.
