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.) + + +v1.11.0 - 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. - - New support for the VXLAN tunnel protocol (see the IETF draft here: - http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-02). - 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. + - 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.
