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.
- 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.

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.

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.

* 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.

- 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

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.

- 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.

- 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.

- 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-<type>", 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.

- 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).

- 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

- 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

- ofproto-provider interface:
- "struct rule" has a new member "used" that ofproto implementations
should maintain by updating with ofproto_rule_update_used().

* Many thanks to Thomas Goirand <zigo@debian.org> for contributing many
of the packaging fixes listed above.
* This version fixes most of the lintian errors described in bug
#663051, but a few remain, so this upload does not close that bug. I
believe that this upload should be suitable for downgrading that bug's
severity.

openvswitch (1.4.0-2+nmu1) unstable; urgency=low
* Non maintainer upload.
* Removes all patches in debian/patches, because they are patching stuff
inconditionally in debian/*, and this should be applied by default.
* Uses the correct ${kernel_source_dir} in debian/dkms.conf.in, so that
the kernel module builds as expected (Closes: #659685).

openvswitch (1.4.0-1) unstable; urgency=low
[ Open vSwitch team ]
* New upstream version
- Compatible with Open vSwitch kernel module included in Linux 3.3.
- New "VLAN splinters" feature to work around buggy device drivers
in old Linux versions. (This feature is deprecated. When
broken device drivers are no longer in widespread use, we will
delete this feature.) See ovs-vswitchd.conf.db(5) for more
information.
- OpenFlow:
- Added ability to match on IPv6 flow label through NXM.
- Added ability to match on ECN bits in IPv4 and IPv6 through NXM.
- Added ability to match on TTL in IPv4 and IPv6 through NXM.
- Added ability to modify ECN bits in IPv4.
- Added ability to modify TTL in IPv4.
- ovs-vswitchd:
- Don't require the "normal" action to use mirrors. 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

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. By
default it remains compatible with the old version and other
standards-based implementations.
- Flow setups are now processed in a round-robin manner across ports
to prevent any single client from monopolizing the CPU and conducting
a denial of service attack.
- Added support for native VLAN tagging. A new "vlan_mode"
parameter can be set for "port". Possible values: "access",
"trunk", "native-tagged" and "native-untagged".
- test-openflowd has been removed. Please use ovs-vswitchd instead.

openvswitch (1.2.0-1) unstable; urgency=low
[ Open vSwitch team ]
* New upstream version
- New "ofproto" abstraction layer to ease porting to hardware
switching ASICs.
- Packaging for Red Hat Enterprise Linux 5.6 and 6.0.
- Datapath support for Linux kernels up to 3.0.
- OpenFlow:
- New "bundle" and "bundle_load" action extensions.
- Database:
- Implement table unique constraints.
- Support cooperative locking between callers.
- ovs-dpctl:
- New "-s" option for "show" command prints packet and byte
counters for each port.
- ovs-ofctl:
- New "--readd" option for "replace-flows".
- ovs-vsctl:
- New "show" command to print an overview of configuration.
- New "comment" command to add remark that explains intentions.
- ovs-brcompatd has been rewritten to fix long-standing bugs.
- ovs-openflowd has been renamed test-openflowd and moved into the
tests directory. 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.
Please use the extensible match extensions instead.
- Removed the Maintenance_Point and Monitor tables in an effort
to simplify 802.1ag configuration.
- Performance and scalability improvements
- Bug fixes
