---------------------
- ovsdb-server:
- * New "monitor2" and "update2" extensions to RFC 7047.
+ * New "monitor_cond" "monitor_cond_update" and "update2" extensions to
+ RFC 7047.
- OpenFlow:
* OpenFlow 1.1+ OFPT_QUEUE_GET_CONFIG_REQUEST now supports OFPP_ANY.
* OpenFlow 1.4+ OFPMP_QUEUE_DESC is now supported.
now implemented. Only flow mod and port mod messages are supported
in bundles.
* New OpenFlow extension NXM_NX_MPLS_TTL to provide access to MPLS TTL.
+ * New output option, output(port=N,max_len=M), to allow truncating a
+ packet to size M bytes when outputting to port N.
+ * New command OFPGC_ADD_OR_MOD for OFPT_GROUP_MOD message that adds a
+ new group or modifies an existing groups
+ - Improved OpenFlow version compatibility for actions:
+ * New OpenFlow extension to support the "group" action in OpenFlow 1.0.
+ * OpenFlow 1.0 "enqueue" action now properly translated to OpenFlow 1.1+.
+ * OpenFlow 1.1 "mod_nw_ecn" and OpenFlow 1.1+ "mod_nw_ttl" actions now
+ properly translated to OpenFlow 1.0.
- ovs-ofctl:
* queue-get-config command now allows a queue ID to be specified.
* '--bundle' option can now be used with OpenFlow 1.3.
* New option "--color" to produce colorized output for some commands.
+ * New option '--may-create' to use OFPGC_ADD_OR_MOD in mod-group command.
+ - IPFIX:
+ * New "sampling_port" option for "sample" action to allow sampling
+ ingress and egress tunnel metadata with IPFIX.
+ * New ovs-ofctl commands "dump-ipfix-bridge" and "dump-ipfix-flow" to
+ dump bridge IPFIX statistics and flow based IPFIX statistics.
+ * New setting other-config:virtual_obs_id to add an arbitrary string
+ to IPFIX records.
+ - Linux:
+ * New QoS type "linux-noop" that prevents Open vSwitch from trying to
+ manage QoS for a given port (useful when other software manages QoS).
- DPDK:
* New option "n_rxq" for PMD interfaces.
Old 'other_config:n-dpdk-rxqs' is no longer supported.
+ Not supported by vHost interfaces. For them number of rx and tx queues
+ is applied from connected virtio device.
* New appctl command 'dpif-netdev/pmd-rxq-show' to check the port/rxq
assignment.
* Type of log messages from PMD threads changed from INFO to DBG.
* QoS functionality with sample egress-policer implementation.
+ * The mechanism for configuring DPDK has changed to use database
+ * Sensible defaults have been introduced for many of the required
+ configuration options
+ * DB entries have been added for many of the DPDK EAL command line
+ arguments. Additional arguments can be passed via the dpdk-extra
+ entry.
+ * Add ingress policing functionality.
+ * PMD threads servicing vHost User ports can now come from the NUMA
+ node that device memory is located on if CONFIG_RTE_LIBRTE_VHOST_NUMA
+ is enabled in DPDK.
+ - Increase number of registers to 16.
- ovs-benchmark: This utility has been removed due to lack of use and
bitrot.
- ovs-appctl:
* New "vlog/close" command.
+ - ovs-ctl:
+ * Added the ability to selectively start the forwarding and database
+ functions (ovs-vswitchd and ovsdb-server, respectively).
- ovsdb-server:
* Remove max number of sessions limit, to enable connection scaling
testing.
* Introduced SELinux policy package.
- Datapath Linux kernel compatibility.
* Dropped support for kernel older than 3.10.
+ * Removed VLAN splinters feature.
+ * Support for truncate action.
+ * Datapath supports kernel upto 4.6.
- Tunnels:
* Flow based tunnel match and action can be used for IPv6 address using
tun_ipv6_src, tun_ipv6_dst fields.
- * Added support for IPv6 tunnels to native tunneling.
+ * Added support for IPv6 tunnels, for details checkout FAQ.
+ - A wrapper script, 'ovs-tcpdump', to easily port-mirror an OVS port and
+ watch with tcpdump
+ - Introduce --no-self-confinement flag that allows daemons to work with
+ sockets outside their run directory.
+ - ovs-pki: Changed message digest algorithm from SHA-1 to SHA-512 because
+ SHA-1 is no longer secure and some operating systems have started to
+ disable it in OpenSSL.
