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. + - 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.

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. + + +v1.9.0 - xx xxx xxxx +-------------------- + - 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. @@ -9,6 +77,21 @@ 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.
