As a consequence, + using Open vSwitch 2.5 or later on XenServer 6.5 or earlier (which + have Python 2.4) requires first installing Python 2.7. + - OpenFlow: + * Group chaining (where one OpenFlow group triggers another) is + now supported. + * OpenFlow 1.4+ "importance" is now considered for flow eviction. + * OpenFlow 1.4+ OFPTC_EVICTION is now implemented. + * OpenFlow 1.4+ OFPTC_VACANCY_EVENTS is now implemented. + * OpenFlow 1.4+ OFPMP_TABLE_DESC is now implemented. + * Allow modifying the ICMPv4/ICMPv6 type and code fields. + * OpenFlow 1.4+ OFPT_SET_ASYNC_CONFIG and OFPT_GET_ASYNC_CONFIG are + now implemented. + - ovs-ofctl: + * New "out_group" keyword for OpenFlow 1.1+ matching on output group. + - Tunnels: + * Geneve tunnels can now match and set options and the OAM bit. + * The nonstandard GRE64 tunnel extension has been dropped. + - Support Multicast Listener Discovery (MLDv1 and MLDv2). + - Add 'symmetric_l3l4' and 'symmetric_l3l4+udp' hash functions. + - sFlow agent now reports tunnel and MPLS structures. + - New 'check-system-userspace', 'check-kmod' and 'check-kernel' Makefile + targets to run a new system testsuite. These tests can be run inside + a Vagrant box. See INSTALL.md for details + - Mark --syslog-target argument as deprecated. It will be removed in + the next OVS release. + - Added --user option to all daemons + - Add support for connection tracking through the new "ct" action + and "ct_state"/"ct_zone"/"ct_mark"/"ct_label" match fields. Only + available on Linux kernels with the connection tracking module loaded. + - Add experimental version of OVN. OVN, the Open Virtual Network, is a + system to support virtual network abstraction. OVN complements the + existing capabilities of OVS to add native support for virtual network + abstractions, such as virtual L2 and L3 overlays and security groups. + - RHEL packaging: + * DPDK ports may now be created via network scripts (see README.RHEL). + - DPDK: + * Requires DPDK 2.2 + * Added multiqueue support to vhost-user + * Note: QEMU 2.5+ required for multiqueue support + +v2.4.0 - 20 Aug 2015 +--------------------- + - Flow table modifications are now atomic, meaning that each packet + now sees a coherent version of the OpenFlow pipeline. For + example, if a controller removes all flows with a single OpenFlow + "flow_mod", no packet sees an intermediate version of the OpenFlow + pipeline where only some of the flows have been deleted. + - Added support for SFQ, FQ_CoDel and CoDel qdiscs. + - Add bash command-line completion support for ovs-vsctl Please check + utilities/ovs-command-compgen.INSTALL.md for how to use. + - The MAC learning feature now includes per-port fairness to mitigate + MAC flooding attacks. + - New support for a "conjunctive match" OpenFlow extension, which + allows constructing OpenFlow matches of the form "field1 in + {a,b,c...} AND field2 in {d,e,f...}" and generalizations. For details, + see documentation for the "conjunction" action in ovs-ofctl(8). + - Add bash command-line completion support for ovs-appctl/ovs-dpctl/ + ovs-ofctl/ovsdb-tool commands. Please check + utilities/ovs-command-compgen.INSTALL.md for how to use. + - The "learn" action supports a new flag "delete_learned" that causes + the learned flows to be deleted when the flow with the "learn" action + is deleted. + - Basic support for the Geneve tunneling protocol. It is not yet + possible to generate or match options. This is planned for a future + release. The protocol is documented at + http://tools.ietf.org/html/draft-gross-geneve-00 + - The OVS database now reports controller rate limiting statistics. + - sflow now exports information about LACP-based bonds, port names, and + OpenFlow port numbers, as well as datapath performance counters. + - ovs-dpctl functionality is now available for datapaths integrated + into ovs-vswitchd, via ovs-appctl. Some existing ovs-appctl + commands are now redundant and will be removed in a future + release. See ovs-vswitchd(8) for details. + - OpenFlow: + * OpenFlow 1.4 bundles are now supported for flow mods and port + mods. For flow mods, both 'atomic' and 'ordered' bundle flags + are trivially supported, as all bundled messages are executed + in the order they were added and all flow table modifications + are now atomic to the datapath. Port mods may not appear in + atomic bundles, as port status modifications are not atomic. + * IPv6 flow label and neighbor discovery fields are now modifiable. + * OpenFlow 1.5 extended registers are now supported. + * The OpenFlow 1.5 actset_output field is now supported. + * OpenFlow 1.5 Copy-Field action is now supported. + * OpenFlow 1.5 masked Set-Field action is now supported. + * OpenFlow 1.3+ table features requests are now supported (read-only). + * Nicira extension "move" actions may now be included in action sets. + * "resubmit" actions may now be included in action sets. The resubmit + is executed last, and only if the action set has no "output" or "group" + action. + * OpenFlow 1.4+ flow "importance" is now maintained in the flow table. + * A new Netronome extension to OpenFlow 1.5+ allows control over the + fields hashed for OpenFlow select groups. See "selection_method" and + related options in ovs-ofctl(8) for details. + - ovs-ofctl has a new '--bundle' option that makes the flow mod commands + ('add-flow', 'add-flows', 'mod-flows', 'del-flows', and 'replace-flows') + use an OpenFlow 1.4 bundle to operate the modifications as a single + atomic transaction. If any of the flow mods in a transaction fail, none + of them are executed. All flow mods in a bundle appear to datapath + lookups simultaneously. + - ovs-ofctl 'add-flow' and 'add-flows' commands now accept arbitrary flow + mods as an input by allowing the flow specification to start with an + explicit 'add', 'modify', 'modify_strict', 'delete', or 'delete_strict' + keyword. A missing keyword is treated as 'add', so this is fully + backwards compatible. With the new '--bundle' option all the flow mods + are executed as a single atomic transaction using an OpenFlow 1.4 bundle. + - ovs-pki: Changed message digest algorithm from MD5 to SHA-1 because + MD5 is no longer secure and some operating systems have started to disable + it in OpenSSL. + - ovsdb-server: New OVSDB protocol extension allows inequality tests on + "optional scalar" columns. See ovsdb-server(1) for details. + - ovs-vsctl now permits immutable columns in a new row to be modified in + the same transaction that creates the row. + - test-controller has been renamed ovs-testcontroller at request of users + who find it useful for testing basic OpenFlow setups. It is still not + a necessary or desirable part of most Open vSwitch deployments. + - Support for travis-ci.org based continuous integration builds has been + added. Build failures are reported to build@openvswitch.org. See INSTALL.md + file for additional details. + - Support for the Rapid Spanning Tree Protocol (IEEE 802.1D-2004). + The implementation has been tested successfully against the Ixia Automated + Network Validation Library (ANVL). + - Stats are no longer updated on fake bond interface. + - Keep active bond slave selection across OVS restart. + - A simple wrapper script, 'ovs-docker', to integrate OVS with Docker + containers. If and when there is a native integration of Open vSwitch + with Docker, the wrapper script will be retired. + - Added support for DPDK Tunneling. VXLAN, GRE, and Geneve are supported + protocols. This is generic tunneling mechanism for userspace datapath. + - Support for multicast snooping (IGMPv1, IGMPv2 and IGMPv3) + - Support for Linux kernels up to 4.0.x + - The documentation now use the term 'destination' to mean one of syslog, + console or file for vlog logging instead of the previously used term + 'facility'. + - Support for VXLAN Group Policy extension + - Initial support for the IETF Auto-Attach SPBM draft standard. This + contains rudimentary support for the LLDP protocol as needed for + Auto-Attach. + - The default OpenFlow and OVSDB ports are now the IANA-assigned + numbers. OpenFlow is 6653 and OVSDB is 6640. + - Support for DPDK vHost. + - Support for outer UDP checksums in Geneve and VXLAN. + - The kernel vports with dependencies are no longer part of the overall + openvswitch.ko but built and loaded automatically as individual kernel + modules (vport-*.ko). + - Support for STT tunneling. + - ovs-sim: New developer tool for simulating multiple OVS instances. + See ovs-sim(1) for more information. + - Support to configure method (--syslog-method argument) that determines + how daemons will talk with syslog. + - Support for "ovs-appctl vlog/list-pattern" command that lets to query + logging message format for each destination. + + +v2.3.0 - 14 Aug 2014 +--------------------- + - OpenFlow 1.1, 1.2, and 1.3 are now enabled by default in + ovs-vswitchd. + - Linux kernel datapath now has an exact match cache optimizing the + flow matching process. + - Datapath flows now have partially wildcarded tranport port field + matches. This reduces userspace upcalls, but increases the + number of different masks in the datapath. The kernel datapath + exact match cache removes the overhead of matching the incoming + packets with the larger number of masks, but when paired with an + older kernel module, some workloads may perform worse with the + new userspace. + - Compatibility with autoconf 2.63 (previously >=2.64) + +v2.2.0 - Internal Release +--------------------- + - Internal ports are no longer brought up by default, because it + should be an administrator task to bring up devices as they are + configured properly. + - ovs-vsctl now reports when ovs-vswitchd fails to create a new port or + bridge. + - Port creation and configuration errors are now stored in a new error + column of the Interface table and included in 'ovs-vsctl show'. + - The "ovsdbmonitor" graphical tool has been removed, because it was + poorly maintained and not widely used. + - New "check-ryu" Makefile target for running Ryu tests for OpenFlow + controllers against Open vSwitch. See INSTALL.md for details. + - Added IPFIX support for SCTP flows and templates for ICMPv4/v6 flows. + - Upon the receipt of a SIGHUP signal, ovs-vswitchd no longer reopens its + log file (it will terminate instead). Please use 'ovs-appctl vlog/reopen' + instead. + - Support for Linux kernels up to 3.14. From Kernel 3.12 onwards OVS uses + tunnel API for GRE and VXLAN. + - Added DPDK support. + - Added support for custom vlog patterns in Python + + +v2.1.0 - 19 Mar 2014 +--------------------- + - Address prefix tracking support for flow tables. New columns + "prefixes" in OVS-DB table "Flow_Table" controls which packet + header fields are used for address prefix tracking. Prefix + tracking allows the classifier to skip rules with longer than + necessary prefixes, resulting in better wildcarding for datapath + flows. Default configuration is to not use any fields for prefix + tracking. However, if any flow tables contain both exact matches + and masked matches for IP address fields, OVS performance may be + increased by using this feature. + * As of now, the fields for which prefix lookup can be enabled + are: 'tun_id', 'tun_src', 'tun_dst', 'nw_src', 'nw_dst' (or + aliases 'ip_src' and 'ip_dst'), 'ipv6_src', and 'ipv6_dst'. + (Using this feature for 'tun_id' would only make sense if the + tunnel IDs have prefix structure similar to IP addresses.) + * There is a maximum number of fields that can be enabled for any + one flow table. Currently this limit is 3. + * Examples: + $ ovs-vsctl set Bridge br0 flow_tables:0=@N1 -- \ + --id=@N1 create Flow_Table name=table0 + $ ovs-vsctl set Bridge br0 flow_tables:1=@N1 -- \ + --id=@N1 create Flow_Table name=table1 + $ ovs-vsctl set Flow_Table table0 prefixes=ip_dst,ip_src + $ ovs-vsctl set Flow_Table table1 prefixes=[] + - TCP flags matching: OVS now supports matching of TCP flags. This + has an adverse performance impact when using OVS userspace 1.10 + or older (no megaflows support) together with the new OVS kernel + module. It is recommended that the kernel and userspace modules + both are upgraded at the same time. + - The default OpenFlow and OVSDB ports will change to + IANA-assigned numbers in a future release. Consider updating + your installations to specify port numbers instead of using the + defaults. + - OpenFlow: + * The OpenFlow 1.1+ "Write-Actions" instruction is now supported. + * OVS limits the OpenFlow port numbers it assigns to port 32767 and + below, leaving port numbers above that range free for assignment + by the controller. + * ovs-vswitchd now honors changes to the "ofport_request" column + in the Interface table by changing the port's OpenFlow port + number. + * The Open vSwitch software switch now supports OpenFlow groups. + - ovs-vswitchd.conf.db.5 man page will contain graphviz/dot + diagram only if graphviz package was installed at the build time. + - Support for Linux kernels up to 3.11 + - ovs-dpctl: + The "show" command also displays mega flow mask stats. + - ovs-ofctl: + * New command "ofp-parse-pcap" to dump OpenFlow from PCAP files. + - ovs-controller has been renamed test-controller. It is no longer + packaged or installed by default, because too many users assumed + incorrectly that ovs-controller was a necessary or desirable part + of an Open vSwitch deployment. + - Added vlog option to export to a UDP syslog sink. + - ovsdb-client: + * The "monitor" command can now monitor all tables in a database, + instead of being limited to a single table. + - The flow-eviction-threshold has been replaced by the flow-limit which is a + hard limit on the number of flows in the datapath. It defaults to 200,000 + flows. OVS automatically adjusts this number depending on network + conditions. + - Added IPv6 support for active and passive socket communications. + + +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). @@ -34,6 +333,10 @@ v2.0.0 - xx xxx xxxx * New "ofp-parse" for printing OpenFlow messages read from a file. * New commands for OpenFlow 1.1+ groups. - 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.
