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. + - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit" commands + available through ovs-appctl allow control over logging rate limits. + - The OpenFlow "dp_desc" may now be configured by setting the value of + other-config:dp-desc in the Bridge table. + - Path MTU discovery is no longer supported. + - Backward-incompatible changes: + - Earlier Open vSwitch versions treated ANY as a wildcard in flow + syntax. OpenFlow 1.1 adds a port named ANY, which introduces a + conflict. ANY was rarely used in flow syntax, so we chose to + retire that meaning of ANY in favor of the OpenFlow 1.1 meaning. + - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit) is + no longer supported. + - Patch ports are implemented in userspace. + - Tunneling requires the version of the kernel module paired with Open + vSwitch 1.9.0 or later. + + +v1.9.0 - xx xxx xxxx +-------------------- + - The tunneling code no longer assumes input and output keys are symmetric. + If they are not, PMTUD needs to be disabled for tunneling to work. Note + this only applies to flow-based keys. + - Datapath: + - Support for ipv6 set action. + - SKB mark matching and setting. + - support for Linux kernels up to 3.8 + - FreeBSD is now a supported platform, thanks to code contributions from + Gaetano Catalli, Ed Maste, and Giuseppe Lettieri. + - ovs-bugtool: New --ovs option to report only OVS related information. + - New %t and %T log escapes to identify the subprogram within a + cooperating group of processes or threads that emitted a log message. + The default log patterns now include this information. + - OpenFlow: + - Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL + fields in IPv6 neighbor discovery messages, and IPv6 flow label. + - Adds support for writing to the metadata field for a flow. + - It is possible to request the OpenFlow port number with the + "ofport_request" column in the Interface table. + - ovs-ofctl: + - Commands and actions that accept port numbers now also accept keywords + that represent those ports (such as LOCAL, NONE, and ALL). This is + also the recommended way to specify these ports, for compatibility + with OpenFlow 1.1 and later (which use the OpenFlow 1.0 numbers + for these ports for different purposes). + - ovs-dpctl: + - Support requesting the port number with the "port_no" option in + the "add-if" command. + - The "dump-flows" and "del-flows" no longer require an argument + if only one datapath exists. + - ovs-appctl: + - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command + that mimic the equivalent ovs-dpctl commands. + - ovs-pki: The "online PKI" features have been removed, along with + the ovs-pki-cgi program that facilitated it, because of some + alarmist insecurity claims. We do not believe that these claims + are true, but because we do not know of any users for this + feature it seems better on balance to remove it. (The ovs-pki-cgi + program was not included in distribution packaging.) + - Tunnel Path MTU Discovery default value was set to 'disabled'. This + feature is deprecated and will be removed soon. + - ovsdb-server now enforces the immutability of immutable columns. This + was not enforced in earlier versions due to an oversight. + - New support for a nonstandard form of GRE that supports a 64-bit key. + - The ofproto library is now responsible for assigning OpenFlow port + numbers. An ofproto implementation should assign them when + port_construct() is called. + - All dpif-based bridges of a particular type share a common + datapath called "ovs-", e.g. "ovs-system". The ovs-dpctl + commands will now return information on that shared datapath. To + get the equivalent bridge-specific information, use the new + "ovs-appctl dpif/*" commands. + - Tunnel header caching removed. + - The following features are now deprecated. They will be removed no + earlier than February 2013. Please email dev@openvswitch.org with + concerns. + - Bridge compatibility. + - Stable bond mode. + - The autopath action. + - Interface type "null". + - Numeric values for reserved ports (see "ovs-ofctl" note above). + - Tunnel Path MTU Discovery. + - CAPWAP tunnel support. + - The data in the RARP packets can now be matched in the same way as the + data in ARP packets. + + +v1.8.0 - xx xxx xxxx ------------------------ + - New FAQ. Please send updates and additions! + - Authors of controllers, please read the new section titled "Action + Reproduction" in DESIGN, which describes an Open vSwitch change in + behavior in corner cases that may affect some controllers. + - ovs-l3ping: + - A new test utility that can create L3 tunnel between two Open + vSwitches and detect connectivity issues. - ovs-ofctl: + - New --sort and --rsort options for "dump-flows" command. - "mod-port" command can now control all OpenFlow config flags. - - Added support for arbitrary ethernet masks + - OpenFlow: + - Allow general bitwise masking for IPv4 and IPv6 addresses in + IPv4, IPv6, and ARP packets. (Previously, only CIDR masks + were allowed.) + - Allow support for arbitrary Ethernet masks. (Previously, only + the multicast bit in the destination address could be individually + masked.) + - New field OXM_OF_METADATA, to align with OpenFlow 1.1. + - The OFPST_QUEUE request now reports an error if a specified port or + queue does not exist, or for requests for a specific queue on all + ports, if the specified queue does not exist on any port. (Previous + versions generally reported an empty set of results.) + - New "flow monitor" feature to allow controllers to be notified of + flow table changes as they happen. + - Additional protocols are not mirrored and dropped when forward-bpdu is + false. For a full list, see the ovs-vswitchd.conf.db man page. + - Open vSwitch now sends RARP packets in situations where it previously + sent a custom protocol, making it consistent with behavior of QEMU and + VMware. + - All Open vSwitch programs and log files now show timestamps in UTC, + instead the local timezone, by default. -v1.7.0 - xx xxx xxxx +v1.7.0 - 30 Jul 2012 ------------------------ - kernel modules are renamed. openvswitch_mod.ko is now openvswitch.ko and brcompat_mod.ko is now brcompat.ko. - Increased the number of NXM registers to 8. - - Added ability to configure dscp setting for manager and controller + - Added ability to configure DSCP setting for manager and controller connections.
