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". + - 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. + +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-", 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. - New %t and %T log escapes to identify the subprogram within a cooperating group of processes or threads that emitted a log message. @@ -7,10 +111,49 @@ post-v1.8.0 - OpenFlow: - 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. + - Tunneling: + - The tunneling code no longer assumes input and output keys are + symmetric.
