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. + +v2.2.0 - xx xxx xxx +--------------------- + - 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. + - 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 --------------------- + - 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). + * Experimental protocol support for OpenFlow 1.1+ groups. This + does not yet include an implementation in the Open vSwitch + software switch. + * Experimental protocol support for OpenFlow 1.2+ meters. This + does not yet include an implementation in the Open vSwitch + software switch. * 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 @@ -19,12 +127,18 @@ v1.12.0 - xx xxx xxxx 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 3.9 + - Support for Linux kernels up to 3.10 - ovs-ofctl: * 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.
