openvswitch (2.6.90-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - Nothing yet! Try NEWS... -- Open vSwitch team Mon, 15 Aug 2016 19:55:47 -0700 openvswitch (2.6.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - First supported release of OVN. See ovn-architecture(7) for more details. - ovsdb-server: * New "monitor_cond" "monitor_cond_update" and "update2" extensions to RFC 7047. - OpenFlow: * OpenFlow 1.3+ bundles are now supported for group mods as well as flow mods and port mods. Both 'atomic' and 'ordered' bundle flags are supported for group mods as well as flow mods. * OpenFlow 1.1+ OFPT_QUEUE_GET_CONFIG_REQUEST now supports OFPP_ANY. * OpenFlow 1.4+ OFPMP_QUEUE_DESC is now supported. * OpenFlow 1.4+ OFPT_TABLE_STATUS is now supported. * New property-based packet-in message format NXT_PACKET_IN2 with support for arbitrary user-provided data and for serializing flow table traversal into a continuation for later resumption. * New extension message NXT_SET_ASYNC_CONFIG2 to allow OpenFlow 1.4-like control over asynchronous messages in earlier versions of OpenFlow. * OpenFlow 1.3 Extension 230, adding OpenFlow Bundles support, is 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 * The optional OpenFlow packet buffering feature is deprecated in this release, and will be removed in the next OVS release (2.7). After the change OVS always sends the 'buffer_id' as 0xffffffff in packet-in messages and will send an error response if any other value of this field is included in packet-out and flow mod sent by a controller. Controllers are already expected to work properly in cases where the switch can not buffer packets, so this change should not affect existing users. * New OpenFlow extension NXT_CT_FLUSH_ZONE to flush conntrack zones. - 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 and with group mods. * New "bundle" command allows executing a mixture of flow and group mods as a single atomic transaction. * 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 'other_config:pmd-rxq-affinity' field for PMD interfaces, that allows to pin port's rx queues to desired cores. * 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. * Basic connection tracking for the userspace datapath (no ALG, fragmentation or NAT support yet) * Support for DPDK 16.07 * Optional support for DPDK pdump enabled. * Jumbo frame support * Remove dpdkvhostcuse port type. * OVS client mode for vHost and vHost reconnect (Requires QEMU 2.7) - 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. - python: * Added support for Python 3.4+ in addition to existing support for 2.7+. - SELinux: * 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, for details checkout FAQ. * Deprecated support for IPsec tunnels ports. - 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. - Add 'mtu_request' column to the Interface table. It can be used to configure the MTU of non-internal ports. -- Open vSwitch team Mon, 15 Aug 2016 19:53:13 -0700 openvswitch (2.5.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - Dropped support for Python older than version 2.7. 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. -- Open vSwitch team Thu, 03 Dec 2015 23:17:44 -0700 openvswitch (2.4.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - 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. - 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. - GRE64 and ipsec_gre64 tunnel protocol is deprecated and will be removed from OVS v2.5 release. * The openvswitch-testcontroller package is new. It reintroduces the simple OpenFlow controller that was packaged with Open vSwitch prior to version 2.1, 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. -- Open vSwitch team Thu, 20 Aug 2015 17:23:43 -0700 openvswitch (2.3.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - 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. -- Open vSwitch team Thu, 14 Aug 2014 11:03:32 -0700 openvswitch (2.2.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - 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 -- Open vSwitch team Wed, 19 Mar 2014 16:08:38 -0700 openvswitch (2.1.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - 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. * The openvswitch-controller package has been removed, because too many users assumed incorrectly that ovs-controller was a necessary or desirable part of an Open vSwitch deployment. -- Open vSwitch team Wed, 19 Mar 2014 16:08:38 -0700 openvswitch (2.0.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - 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). * 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 vSwitch. See README-OFTest for details. - The flow eviction threshold has been moved to the Open_vSwitch table. - Database names are now mandatory when specifying ovsdb-server options 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 3.10 - ovs-ofctl: * New "ofp-parse" for printing OpenFlow messages read from a file. - 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. (Previous versions only reported whole seconds.) -- Open vSwitch team Tue, 15 Oct 2013 15:03:42 -0700 openvswitch (1.11.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - Support for megaflows, which allows wildcarding in the kernel (and any dpif implementation that supports wildcards). Depending on the flow table and switch configuration, flow set up rates are close to the Linux bridge. - The "tutorial" directory contains a new tutorial for some advanced Open vSwitch features. - Stable bond mode has been removed. - The autopath action has been removed. - New support for the data encapsulation format of the LISP tunnel protocol (RFC 6830). An external control plane or manual flow setup is required for EID-to-RLOC mapping. - OpenFlow: * The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow 1.1 and later are now implemented. * New "stack" extension for use in actions, to push and pop from NXM fields. * The "load" and "set_field" actions can now modify the "in_port". (This allows one to enable output to a flow's input port by setting the in_port to some unused value, such as OFPP_NONE.) - ovs-dpctl: * New debugging commands "add-flow", "mod-flow", "del-flow". - In dpif-based bridges, cache action translations, which can improve flow set up performance by 80% with a complicated flow table. - New syslog format, prefixed with "ovs|", to be easier to filter. - RHEL: Removes the default firewall rule that allowed GRE traffic to pass through. Any users that relied on this automatic firewall hole will have to manually configure it. The ovs-ctl(8) manpage documents the "enable-protocol" command that can be used as an alternative. - New CFM demand mode which uses data traffic to indicate interface liveness. -- Open vSwitch team Wed, 28 Aug 2013 14:31:44 -0700 openvswitch (1.10.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - Bridge compatibility support has been removed. 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. - 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. - OpenFlow: - Experimental support for newer versions of OpenFlow. See the "What versions of OpenFlow does Open vSwitch support?" question in the FAQ for more details. - The OpenFlow "dp_desc" may now be configured by setting the value of other-config:dp-desc in the Bridge table. - It is possible to request the OpenFlow port number with the "ofport_request" column in the Interface table. - Tunneling: - New support for the VXLAN tunnel protocol (see the IETF draft here: http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03). - Tunneling requires the version of the kernel module paired with Open vSwitch 1.9.0 or later. - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit) is no longer supported. - Path MTU discovery is no longer supported. - ovs-dpctl: - The "dump-flows" and "del-flows" no longer require an argument if only one datapath exists. - ovs-appctl: - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit" commands available allow control over logging rate limits. - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command that mimic the equivalent ovs-dpctl commands. - 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. - 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. - Patch ports no longer require kernel support, so they now work with FreeBSD and the kernel module built into Linux 3.3 and later. -- Open vSwitch team Wed, 01 May 2013 14:28:21 -0700 openvswitch (1.9.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - 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. - Tunneling: - 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. - New support for a nonstandard form of GRE that supports a 64-bit key. - Tunnel Path MTU Discovery default value was set to 'disabled'. This feature is deprecated and will be removed soon. - Tunnel header caching removed. - 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. - 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.) - ovsdb-server now enforces the immutability of immutable columns. This was not enforced in earlier versions due to an oversight. - 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. -- Open vSwitch team Tue, 26 Feb 2013 11:23:19 -0700 openvswitch (1.8.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version *** Internal only release *** - 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. - 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. -- Open vSwitch team Mon, 16 Jul 2012 16:44:52 +0900 openvswitch (1.7.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - 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 connections. By default, these connections have a DSCP value of Internetwork Control (0xc0). - Added the granular link health statistics, 'cfm_health', to an interface. - OpenFlow: - Added support to mask nd_target for ICMPv6 neighbor discovery flows. - Added support for OpenFlow 1.3 port description (OFPMP_PORT_DESC) multipart messages. - ovs-ofctl: - Added the "dump-ports-desc" command to retrieve port information using the new port description multipart messages. - ovs-test: - Added support for spawning ovs-test server from the client. - Now ovs-test is able to automatically create test bridges and ports. - "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows. - Tripled flow setup performance. - The "coverage/log" command previously available through ovs-appctl has been replaced by "coverage/show". The new command replies with coverage counter values, instead of logging them. -- Open vSwitch team Mon, 30 Jul 2012 17:23:57 +0900 openvswitch (1.6.1-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - Allow OFPP_CONTROLLER as the in_port for packet-out messages. -- Open vSwitch team Mon, 25 Jun 2012 13:52:17 +0900 openvswitch (1.6.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - bonding - LACP bonds no longer fall back to balance-slb when negotiations fail. Instead they drop traffic. - The default bond_mode changed from SLB to active-backup, to protect unsuspecting users from the significant risks of SLB bonds (which are documented in vswitchd/INTERNALS). - Load balancing can be disabled by setting the bond-rebalance-interval to zero. - OpenFlow: - Added support for bitwise matching on TCP and UDP ports. See ovs-ofctl(8) for more information. - NXM flow dumps now include times elapsed toward idle and hard timeouts. - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows controllers more precise control over which OpenFlow messages they receive asynchronously. - New "fin_timeout" action. - Added "fin_timeout" support to "learn" action. - The default MAC learning timeout has been increased from 60 seconds to 300 seconds. The MAC learning timeout is now configurable. - When QoS settings for an interface do not configure a default queue (queue 0), Open vSwitch now uses a default configuration for that queue, instead of dropping all packets as in previous versions. - Logging to console and file will have UTC timestamp as a default for all the daemons. An example of the default format is 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default format as before. - New support for limiting the number of flows in an OpenFlow flow table, with configurable policy for evicting flows upon overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) for more information. - New "enable-async-messages" column in the Controller table. If set to false, OpenFlow connections to the controller will initially have all asynchronous messages disabled, overriding normal OpenFlow behavior. - ofproto-provider interface: - "struct rule" has a new member "used" that ofproto implementations should maintain by updating with ofproto_rule_update_used(). - ovsdb-client: - The new option --timestamp causes the "monitor" command to print a timestamp with every update. - CFM module CCM broadcasts can now be tagged with an 802.1p priority. -- Open vSwitch team Fri, 24 Feb 2012 11:12:48 +0900 openvswitch (1.5.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - OpenFlow: - Added support for querying, modifying, and deleting flows based on flow cookie when using NXM. - Added new NXM_PACKET_IN format. - ovs-ofctl: - Added daemonization support to the monitor and snoop commands. - ovs-vsctl: - The "find" command supports new set relational operators {=}, {!=}, {<}, {>}, {<=}, and {>=}. - ovsdb-tool now uses the typical database and schema installation directories as defaults. -- Open vSwitch team Fri, 01 June 2012 13:06:00 +0900 openvswitch (1.4.0+git20120426-1) unstable; urgency=low * New upstream release fixing the following bugs: o Broken log rotation. o Use-after-free error when ports disappear. o Minor memory leaks. o Testsuite failures on big-endian architectures. -- Ben Pfaff Thu, 26 Apr 2012 13:46:55 -0700 openvswitch (1.4.0+git20120321-1) unstable; urgency=low * New upstream version including: o Features: - ovs-vsctl: Allow "fake bridges" to be created for VLAN 0. - vswitchd: Make the MAC entry aging time configurable. - mac-learning: Increase MAC learning timeout to 300 seconds. o Bug fixes: - netdev-linux: Fix use-after-free when netdev_dump_queues() deletes queues. - netlink-socket: Increase Netlink socket receive buffer size. - ofproto: Fix code that keeps track of MTU. - ovs-monitor-ipsec: Detect correctly IPSEC configuration changes - bond: Incorrectly reported an error in appctl. - socket-util: Unlink Unix domain sockets that bind but fail to connect. - bridge: Remove unwanted ports at time of ofproto creation. - dpif-linux: Make dpif_linux_port_query_by_name() query only one datapath. - ofproto-dpif: Cleanup STP on ports when disabled on their bridge. - configure: Try to extract kernel source directory from build Makefile. - vswitchd: Always configure a default queue for QoS. - ofproto-dpif: Don't output to in_port even if in_port is OFPP_LOCAL. - sflow_agent: Use snprintf() in place of sprintf(). o Packaging: - Move PKI directory to FHS-compliant location.

Traffic will now be properly mirrored for any flows, regardless of their actions. - Track packet and byte statistics sent on mirrors. - ovs-appctl: - New "fdb/flush" command to flush bridge's MAC learning table. - ovs-test: - A new distributed testing tool that allows one to diagnose performance and connectivity issues. This tool currently is not included in RH or Xen packages. - RHEL packaging now supports integration with Red Hat network scripts. - Debian: Depend on python (>= 2.7) | python-argparse instead of python-argparse to avoid pulling in python2.6 (closes: #653645) -- Open vSwitch team Mon, 30 Jan 2012 23:36:00 +0000 openvswitch (1.3.0-1) unstable; urgency=low [ Open vSwitch team ] * New upstream version - OpenFlow: - Added an OpenFlow extension which allows the "output" action to accept NXM fields. - Added an OpenFlow extension for flexible learning. - Bumped number of NXM registers from four to five. - ovs-appctl: - New "version" command to determine version of running daemon. - If no argument is provided for "cfm/show", displays detailed information about all interfaces with CFM enabled. - If no argument is provided for "lacp/show", displays detailed information about all ports with LACP enabled. - ovs-vswitchd: - The software switch now supports 255 OpenFlow tables, instead of just one. By default, only table 0 is consulted, but the new NXAST_RESUBMIT_TABLE action can look up in additional tables. Tables 128 and above are reserved for use by the switch itself; please use only tables 0 through 127. - Add support for 802.1D spanning tree (STP). - Fragment handling extensions: - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4 fields are made available for matching in fragments with offset 0. - New NXM_NX_IP_FRAG match field for matching IP fragments (usable via "ip_frag" in ovs-ofctl). - New ovs-ofctl "get-frags" and "set-frags" commands to get and set fragment handling policy. - CAPWAP tunneling now supports an extension to transport a 64-key.

Its presence confused too many users. Please use ovs-vswitchd instead. - New ovs-benchmark utility to test flow setup performance. - A new log level "off" has been added. Configuring a log facility "off" prevents any messages from being logged to it. Previously, "emer" was effectively "off" because no messages were ever logged at level "emer". Now, errors that cause a process to exit are logged at "emer" level. - "configure" option --with-l26 has been renamed --with-linux, and --with-l26-source has been renamed --with-linux-source. The old names will be removed after the next release, so please update your scripts. - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and datapath/linux-2.6/compat-2.6 directories. - Feature removals: - Dropped support for "tun_id_from_cookie" OpenFlow extension.
