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. + - 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 1.5 (draft) extended registers are now supported. + * OpenFlow 1.5 (draft) Copy-Field action is now supported. + * OpenFlow 1.5 (draft) 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. + - 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 + file for additional details. + - Experimental support for the Rapid Spanning Tree Protocol + (IEEE 802.1D-2004). More conformance and interoperability testing is + still needed, so this should not be enabled on production environments. + - Stats are no longer updated on fake bond interface. + - Keep active bond slave selection across OVS restart. + + +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. + - Support for multicast snooping (IGMPv1 and IGMPv2) + - 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 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. - 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
