|
|
|
- OpenFlow:
|
2017-04-24 11:49:59 -07:00
|
|
|
* All features required by OpenFlow 1.4 are now implemented, so
|
|
|
|
|
ovs-vswitchd now enables OpenFlow 1.4 by default (in addition to
|
|
|
|
|
OpenFlow 1.0 to 1.3).

ovn: Add a case of policy based routing.
OVN currently supports multiple gateway routers (residing on
different chassis) connected to the same logical topology.
When external traffic enters the logical topology, they can enter
from any gateway routers and reach its eventual destination. This
is achieved with proper static routes configured on the gateway
routers.
But when traffic is initiated in the logical space by a logical
port, we do not have a good way to distribute that traffic across
multiple gateway routers.
This commit introduces one particular way to do it. Based on the
source IP address or source IP network of the packet, we can now
jump to a specific gateway router.
This is very useful for a specific use case of Kubernetes.
When traffic is initiated inside a container heading to outside world,
we want to be able to send such traffic outside the gateway router
residing in the same host as that of the container. Since each
host gets a specific subnet, we can use source IP address based
policy routing to decide on the gateway router.
Rationale for using the same routing table for both source and
destination IP address based routing:
Some hardware network vendors support policy routing in a different table
on arbitrary "match". And when a packet enters, if there is a match
in policy based routing table, the default routing table is not
consulted at all. In case of OVN, we mainly want policy based routing
for north-south traffic. We want east-west traffic to flow as-is. Creating
a separate table for policy based routing complicates the configuration
quite a bit. For e.g., if we have a source IP network based rule added,
to decide a particular gateway router as a next hop, we should add rules at
a higher priority for all the connected routes to make sure that east-west
traffic is not effected in the policy based routing table itself.

|
|
|
* ovn-trace:
|
|
|
|
|
- New --ovs option to also print OpenFlow flows.
|
|

|
2016-12-08 13:12:23 -05:00
|
|
|
* Support for managing SSL and remote connection configuration in
|
2016-12-08 13:12:24 -05:00
|
|
|
northbound and southbound databases.
|
2017-01-03 13:29:10 -05:00
|
|
|
* TCP connections to northbound and southbound databases are no
|
|
|
|

longer enabled by default and must be explicitly configured.
|
|

|
|

|
2016-12-23 16:34:48 -08:00
|
|
|
* New appctl "inject-pkt" command in ovn-controller that allows
|
|
|
|
|
packets to be injected into the connected OVS instance.
|
2017-02-10 15:07:28 -08:00
|
|
|
* Distributed logical routers may now be connected directly to
|
|
|
|
|
logical switches with localnet ports, by specifying a
|
|
|
|
|
"redirect-chassis" on the distributed gateway port of the
|
|
|
|
|
logical router. NAT rules may be specified directly on the
|
|
|
|
|
distributed logical router, and are handled either centrally on
|
|
|
|
|
the "redirect-chassis", or in many cases are handled locally on
|
|
|
|
|
the hypervisor where the corresponding logical port resides.
|
|
|
|
|
Gratuitous ARP for NAT addresses on a distributed logical
|
|
|
|
|
router is not yet supported, but will be added in a future
|
|
|
|
|
version.
|
2016-09-14 16:51:27 -07:00

|
|
- Fixed regression in table stats maintenance introduced in OVS
|
|
|
|
|
2.3.0, wherein the number of OpenFlow table hits and misses was
|
|
|
|
|
not accurate.
|
2016-09-13 14:46:16 -07:00
|
|
|
- OpenFlow:
|
2016-09-14 16:51:27 -07:00
|
|
|
* OFPT_PACKET_OUT messages are now supported in bundles.
|
2016-09-16 09:39:13 -07:00
|
|
|
* A new "selection_method=dp_hash" type for OpenFlow select group
|
|
|
|
|
bucket selection that uses the datapath computed 5-tuple hash
|
|
|
|
|
without making datapath flows match the 5-tuple fields, which
|
|
|
|
|
is useful for more efficient load balancing, for example. This
|
|
|
|
|
uses the Netronome extension to OpenFlow 1.5+ that allows
|
|
|
|
|
control over the OpenFlow select groups selection method. See
|
|
|
|
|
"selection_method" and related options in ovs-ofctl(8) for
|
|
|
|
|
details.

|
|
|
- ovs-ofctl:
|
|
|
|
|
* 'bundle' command now supports packet-out messages.
|
|
|
|
|
* New syntax for 'ovs-ofctl packet-out' command, which uses the
|
|
|
|
|
same string parser as the 'bundle' command. The old 'packet-out'
|
|
|
|
|
syntax is deprecated and will be removed in a later OVS
|
|
|
|
|
release.
|
|
|
|
|
* New unixctl "ofctl/packet-out" command, which can be used to
|
|
|
|
|
instruct a flow monitor to issue OpenFlow packet-out messages.
|
2016-10-25 12:38:48 -04:00

|
- Tunnels:
|
|
|
|
|
* TLV mappings for protocols such as Geneve are now segregated on
|
|
|
|
|
a per-OpenFlow bridge basis rather than globally. (The interface
|
|
|
|
|
has not changed.)
|
2016-09-24 11:44:53 -07:00
|
|
|
* Removed support for IPsec tunnels.
|
2016-10-04 13:58:30 +01:00
|
|
|
- DPDK:
|
|
|
|
|
* New option 'n_rxq_desc' and 'n_txq_desc' fields for DPDK interfaces
|
|
|
|
|
which set the number of rx and tx descriptors to use for the given port.
|
2016-11-25 10:41:11 +00:00
|
|
|
* Support for DPDK v16.11.

netdev-dpdk: Enable Rx checksum offloading feature on DPDK physical ports.
Add Rx checksum offloading feature support on DPDK physical ports. By default,
the Rx checksum offloading is enabled if NIC supports. However,
the checksum offloading can be turned OFF either while adding a new DPDK
physical port to OVS or at runtime.
The rx checksum offloading can be turned off by setting the parameter to
'false'. For eg: To disable the rx checksum offloading when adding a port,
'ovs-vsctl add-port br0 dpdk0 -- \
set Interface dpdk0 type=dpdk options:rx-checksum-offload=false'
OR (to disable at run time after port is being added to OVS)
'ovs-vsctl set Interface dpdk0 options:rx-checksum-offload=false'
Similarly to turn ON rx checksum offloading at run time,
'ovs-vsctl set Interface dpdk0 options:rx-checksum-offload=true'
The Tx checksum offloading support is not implemented due to the following
reasons.
1) Checksum offloading and vectorization are mutually exclusive in DPDK poll
mode driver. Vector packet processing is turned OFF when checksum offloading
is enabled which causes significant performance drop at Tx side.
2) Normally, OVS generates checksum for tunnel packets in software at the
'tunnel push' operation, where the tunnel headers are created. However
enabling Tx checksum offloading involves,
*) Mark every packets for tx checksum offloading at 'tunnel_push' and
recirculate.
*) At the time of xmit, validate the same flag and instruct the NIC to do the
checksum calculation. In case NIC doesnt support Tx checksum offloading,
the checksum calculation has to be done in software before sending out the
packets.
No significant performance improvement noticed with Tx checksum offloading
due to the e overhead of additional validations + non vector packet processing.
In some test scenarios, it introduces performance drop too.
Rx checksum offloading still offers 8-9% of improvement on VxLAN tunneling
decapsulation even though the SSE vector Rx function is disabled in DPDK poll
mode driver.

|
* New property-based packet-in message format NXT_PACKET_IN2 with support
|
Implement serializing the state of packet traversal in "continuations".
One purpose of OpenFlow packet-in messages is to allow a controller to
interpose on the path of a packet through the flow tables. If, for
example, the controller needs to modify a packet in some way that the
switch doesn't directly support, the controller should be able to
program the switch to send it the packet, then modify the packet and
send it back to the switch to continue through the flow table.
That's the theory. In practice, this doesn't work with any but the
simplest flow tables. Packet-in messages simply don't include enough
context to allow the flow table traversal to continue. For example:
* Via "resubmit" actions, an Open vSwitch packet can have an
effective "call stack", but a packet-in can't describe it, and
so it would be lost.
* A packet-in can't preserve the stack used by NXAST_PUSH and
NXAST_POP actions.
* A packet-in can't preserve the OpenFlow 1.1+ action set.
* A packet-in can't preserve the state of Open vSwitch mirroring
or connection tracking.
This commit introduces a solution called "continuations". A continuation
is the state of a packet's traversal through OpenFlow flow tables. A
"controller" action with the "pause" flag, which is newly implemented in
this commit, generates a continuation and sends it to the OpenFlow
controller in a packet-in asynchronous message (only NXT_PACKET_IN2
supports continuations, so the controller must configure them with
NXT_SET_PACKET_IN_FORMAT). The controller processes the packet-in,
possibly modifying some of its data, and sends it back to the switch with
an NXT_RESUME request, which causes flow table traversal to continue. In
principle, a single packet can be paused and resumed multiple times.
Another way to look at it is:
- "pause" is an extension of the existing OFPAT_CONTROLLER
action. It sends the packet to the controller, with full
pipeline context (some of which is switch implementation
dependent, and may thus vary from switch to switch).
- A continuation is an extension of OFPT_PACKET_IN, allowing for
implementation dependent metadata.
- NXT_RESUME is an extension of OFPT_PACKET_OUT, with the
semantics that the pipeline processing is continued with the
original translation context from where it was left at the time

ofp-actions: Add truncate action.
The patch adds a new action to support packet truncation. The new action
is formatted as 'output(port=n,max_len=m)', as output to port n, with
packet size being MIN(original_size, m).
One use case is to enable port mirroring to send smaller packets to the
destination port so that only useful packet information is mirrored/copied,
saving some performance overhead of copying entire packet payload. Example
use case is below as well as shown in the testcases:
- Output to port 1 with max_len 100 bytes.
- The output packet size on port 1 will be MIN(original_packet_size, 100).
# ovs-ofctl add-flow br0 'actions=output(port=1,max_len=100)'
- The scope of max_len is limited to output action itself. The following
packet size of output:1 and output:2 will be intact.
# ovs-ofctl add-flow br0 \
'actions=output(port=1,max_len=100),output:1,output:2'
- The Datapath actions shows:
# Datapath actions: trunc(100),1,1,2

ofproto: Add relaxed group_mod command ADD_OR_MOD
This patch adds support for a new Group Mod command OFPGC_ADD_OR_MOD to
OVS for all OpenFlow versions that support groups (OF11 and higher).
The new ADD_OR_MOD creates a group that does not yet exist (like ADD)
and modifies an existing group (like MODIFY).
Rational: In OpenFlow 1.x the Group Mod commands OFPGC_ADD and
OFPGC_MODIFY have strict semantics: ADD fails if the group exists,
while MODIFY fails if the group does not exist. This requires a
controller to exactly know the state of the switch when programming a
group in order not run the risk of getting an OFP Error message in
response. This is hard to achieve and maintain at all times in view of
possible switch and controller restarts or other connection losses
between switch and controller.
Due to the un-acknowledged nature of the Group Mod message programming
groups safely and efficiently at the same time is virtually impossible
as the controller has to either query the existence of the group prior
to each Group Mod message or to insert a Barrier Request/Reply after
every group to be sure that no Error can be received at a later stage
and require a complicated roll-back of any dependent actions taken
between the failed Group Mod and the Error.
In the ovs-ofctl command line the ADD_OR_MOD command is made available
through the new option --may-create in the mod-group command:
$ ovs-ofctl -Oopenflow13 del-groups br-int group_id=100

Known issues:
|
|
|
|
|
- Using openvswitch module in conjunction with upstream Linux tunnels:
|
|
|
|
|
* When using the openvswitch module distributed with OVS against kernel
|
|
|
|
|
versions 4.4 to 4.6, the openvswitch module cannot be loaded or used at
|
|
|
|
|
the same time as "ip_gre".
|
|
|
|
|
- Conntrack FTP ALGs: When using the openvswitch module distributed with
|
|
|
|
|
OVS, particular Linux distribution kernels versions may provide diminished
|
|
|
|
|
functionality. This typically affects active FTP data connections when
|
|
|
|
|
using "actions=ct(alg=ftp),..." in flow tables. Specifically:
|
|
|
|
|
* Centos 7.1 kernels (3.10.0-2xx) kernels are unable to correctly set
|
|
|
|
|
up expectations for FTP data connections in multiple zones,
|
|
|
|
|
eg "actions=ct(zone=1,alg=ftp),ct(zone=2,alg=ftp),...". Executing the
|
|
|
|
|
"ct" action for subsequent data connections may fail to determine that
|
|
|
|
|
the data connection is "related" to an existing connection.
|
|
|
|
|
* Centos 7.2 kernels (3.10.0-3xx) kernels may not establish FTP ALG state
|
|
|
|
|
correctly for NATed connections. As a result, flows that perform NAT,
|
|
|
|
|
eg "actions=ct(nat,ftp=alg,table=1),..." may fail to NAT the packet,
|
|
|
|
|
and will populate the "ct_state=inv" bit in the flow.

Add support for connection tracking.
This patch adds a new action and fields to OVS that allow connection
tracking to be performed. This support works in conjunction with the
Linux kernel support merged into the Linux-4.3 development cycle.
Packets have two possible states with respect to connection tracking:
Untracked packets have not previously passed through the connection
tracker, while tracked packets have previously been through the
connection tracker. For OpenFlow pipeline processing, untracked packets
can become tracked, and they will remain tracked until the end of the
pipeline. Tracked packets cannot become untracked.
Connections can be unknown, uncommitted, or committed. Packets which are
untracked have unknown connection state. To know the connection state,
the packet must become tracked. Uncommitted connections have no
connection state stored about them, so it is only possible for the
connection tracker to identify whether they are a new connection or
whether they are invalid. Committed connections have connection state
stored beyond the lifetime of the packet, which allows later packets in
the same connection to be identified as part of the same established
connection, or related to an existing connection - for instance ICMP
error responses.
The new 'ct' action transitions the packet from "untracked" to
"tracked" by sending this flow through the connection tracker.
The following parameters are supported initally:
- "commit": When commit is executed, the connection moves from
uncommitted state to committed state. This signals that information
about the connection should be stored beyond the lifetime of the
packet within the pipeline. This allows future packets in the same
connection to be recognized as part of the same "established" (est)
connection, as well as identifying packets in the reply (rpl)
direction, or packets related to an existing connection (rel).
- "zone=[u16|NXM]": Perform connection tracking in the zone specified.
Each zone is an independent connection tracking context. When the
"commit" parameter is used, the connection will only be committed in
the specified zone, and not in other zones. This is 0 by default.
- "table=NUMBER": Fork pipeline processing in two. The original instance
of the packet will continue processing the current actions list as an
untracked packet. An additional instance of the packet will be sent to
the connection tracker, which will be re-injected into the OpenFlow
pipeline to resume processing in the specified table, with the
ct_state and other ct match fields set. If the table is not specified,
then the packet is submitted to the connection tracker, but the
pipeline does not fork and the ct match fields are not populated. It
is strongly recommended to specify a table later than the current
table to prevent loops.
When the "table" option is used, the packet that continues processing in
the specified table will have the ct_state populated. The ct_state may
have any of the following flags set:
- Tracked (trk): Connection tracking has occurred.
- Reply (rpl): The flow is in the reply direction.
- Invalid (inv): The connection tracker couldn't identify the connection.
- New (new): This is the beginning of a new connection.
- Established (est): This is part of an already existing connection.
- Related (rel): This connection is related to an existing connection.
For more information, consult the ovs-ofctl(8) man pages.
Below is a simple example flow table to allow outbound TCP traffic from
port 1 and drop traffic from port 2 that was not initiated by port 1:
table=0,priority=1,action=drop
table=0,arp,action=normal
table=0,in_port=1,tcp,ct_state=-trk,action=ct(commit,zone=9),2
table=0,in_port=2,tcp,ct_state=-trk,action=ct(zone=9,table=1)
table=1,in_port=2,ct_state=+trk+est,tcp,action=1
table=1,in_port=2,ct_state=+trk+new,tcp,action=drop
Based on original design by Justin Pettit, contributions from Thomas
Graf and Daniele Di Proietto.

- Add support for connection tracking through the new "ct" action
|
Add connection tracking label support.
This patch adds a new 128-bit metadata field to the connection tracking
interface. When a label is specified as part of the ct action and the
connection is committed, the value is saved with the current connection.
Subsequent ct lookups with the table specified will expose this metadata
as the "ct_label" field in the flow.
For example, to allow new TCP connections from port 1->2 and only allow
established connections from port 2->1, and to associate a label with
those connections:
table=0,priority=1,action=drop
table=0,arp,action=normal
table=0,in_port=1,tcp,action=ct(commit,exec(set_field:1->ct_label)),2
table=0,in_port=2,ct_state=-trk,tcp,action=ct(table=1)
table=1,in_port=2,ct_state=+trk,ct_label=1,tcp,action=1

mac-learning: Implement per-port MAC learning fairness.
In "MAC flooding", an attacker transmits an overwhelming number of frames
with unique Ethernet source address on a switch port. The goal is to
force the switch to evict all useful MAC learning table entries, so that
its behavior degenerates to that of a hub, flooding all traffic. In turn,
that allows an attacker to eavesdrop on the traffic of other hosts attached
to the switch, with all the risks that that entails.
Before this commit, the Open vSwitch "normal" action that implements its
standalone switch behavior (and that can be used by OpenFlow controllers
as well) was vulnerable to MAC flooding attacks. This commit fixes the
problem by implementing per-port fairness for MAC table entries: when
the MAC table is at its maximum size, MAC table eviction always deletes an
entry from the port with the most entries. Thus, MAC entries will never
be evicted from ports with only a few entries if a port with a huge number
of entries exists.
Controllers could introduce their own MAC flooding vulnerabilities into
OVS. For a controller that adds destination MAC based flows to an OpenFlow
flow table as a reaction to "packet-in" events, such a bug, if it exists,
would be in the controller code itself and would need to be fixed in the
controller. For a controller that relies on the Open vSwitch "learn"
action to add destination MAC based flows, Open vSwitch has existing
support for eviction policy similar to that implemented in this commit
through the "groups" column in the Flow_Table table documented in
ovs-vswitchd.conf.db(5); we recommend that users of "learn" not already
familiar with eviction groups to read that documentation.
In addition to implementation of per-port MAC learning fairness,
this commit includes some closely related changes:
- Access to client-provided "port" data in struct mac_entry
is now abstracted through helper functions, which makes it
easier to ensure that the per-port data structures are maintained
consistently.
- The mac_learning_changed() function, which had become trivial,
vestigial, and confusing, was removed. Its functionality was folded
into the new function mac_entry_set_port().
- Many comments were added and improved; there had been a lot of
comment rot in previous versions.

utilities: Add bash command-line completion script.
This patch adds bash command-line completion script for ovs-appctl,
ovs-dpctl, ovs-ofctl and ovsdb-tool command. Right now, the script
can do the following:
- display available completion or complete on unfinished user input
(long option, subcommand, and argument).
- once the subcommand (e.g. ofproto/trace) has been given, the
script will print the subcommand format.
- the script can convert between keywords like 'bridge/port/interface/dp'
and the available record in ovsdb.
The limitations are:
- only support small set of important keywords
(dp, datapath, bridge, switch, port, interface, iface).
- does not support parsing of nested options
(e.g. ovsdb-tool create [db [schema]]).
- does not support expansion on repeatitive argument
(e.g. ovs-dpctl show [dp...]).
- only support matching on long options, and only in the format
(--option [arg], i.e. should not use --option=[arg]).
To use the script, either copy it inside /etc/bash_completion.d/
or manually run it via . ovs-command-compgen.bash.
Also, a unit testsuite is provided as ovs-command-compgen-test.bash.
It is suggested that this test script be run only inside
tutorial/sandbox directory.

2014-04-28 14:45:07 -07:00
|
|
|
---------------------
|
Enable OpenFlow 1.0, 1.1, 1.2, and 1.3 by default.
The Open vSwitch software switch now supports all the required features of
OpenFlow 1.0 through 1.3, with one known trivial exception[*]. Enable them
by default in ovs-vswitchd.
For now, ovs-ofctl only enables OpenFlow 1.0 by default. This is
because ovs-ofctl implements command such as "add-flow" as raw
OpenFlow requests, but those requests have subtly different semantics
in different OpenFlow versions. For example:
- In OpenFlow 1.0, a "mod-flow" operation that does not find any
existing flow to modify adds a new flow.
- In OpenFlow 1.1, a "mod-flow" operation that does not find any
existing flow to modify adds a new flow, but only if the
mod-flow did not match on the flow cookie.
- In OpenFlow 1.2 and a later, a "mod-flow" operation never adds a
new flow.
[*] OpenFlow 1.1, but not any earlier or later version of OpenFlow,
requires support for VLANs introduced by Ethertype 0x88a8, but Open
vSwitch does not support this Ethertype.

|
|
- OpenFlow 1.1, 1.2, and 1.3 are now enabled by default in
|
|
|
|
|
ovs-vswitchd.
|
2014-04-30 14:09:08 -07:00
|
|
|
- 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.

2013-12-23 16:17:50 -08:00
|
|
|
---------------------
|
2014-04-01 18:05:20 -03:00
|
|
|
- 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: Improve error reporting
ovs-vsctl is a command-line interface to the Open vSwitch database,
and as such it just modifies the desired Open vSwitch configuration in
the database. ovs-vswitchd, on the other hand, monitors the database
and implements the actual configuration specified in the database.
This can lead to surprises when the user makes a change to the
database, with ovs-vsctl, that ovs-vswitchd cannot actually
implement. In such a case, the ovs-vsctl command silently succeeds
(because the database was successfully updated) but its desired
effects don't actually take place. One good example of such a change
is attempting to add a port with a misspelled name (e.g. ``ovs-vsctl
add-port br0 fth0'', where fth0 should be eth0); another is creating
a bridge or a port whose name is longer than supported
(e.g. ``ovs-vsctl add-br'' with a 16-character bridge name on
Linux). It can take users a long time to realize the error, because it
requires looking through the ovs-vswitchd log.
The patch improves the situation by checking whether operations that
ovs executes succeed and report an error when
they do not. This patch only report add-br and add-port
operation errors by examining the `ofport' value that
ovs-vswitchd stores into the database record for the newly created
interface. Until ovs-vswitchd finishes implementing the new
configuration, this column is empty, and after it finishes it is
either -1 (on failure) or a positive number (on success).

2014-03-27 17:10:31 +01:00
|
|
|
- ovs-vsctl now reports when ovs-vswitchd fails to create a new port or
|
|
|
|
|
bridge.
|
2014-04-10 12:50:11 +02:00
|
|
|
- Port creation and configuration errors are now stored in a new error
|
|
|
|
|
column of the Interface table and included in 'ovs-vsctl show'.
|
2014-01-10 15:25:40 -08:00
|
|
|
- The "ovsdbmonitor" graphical tool has been removed, because it was
|
|
|
|
|
poorly maintained and not widely used.
|
2014-02-14 10:34:58 -08:00
|
|
|
- New "check-ryu" Makefile target for running Ryu tests for OpenFlow
|
2014-10-28 11:19:52 +01:00
|
|
|
controllers against Open vSwitch. See INSTALL.md for details.
|
2014-02-19 14:23:39 -08:00
|
|
|
- Added IPFIX support for SCTP flows and templates for ICMPv4/v6 flows.
|
2014-02-20 14:58:36 -08:00
|
|
|
- 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.
|
2014-05-01 15:50:48 -07:00
|
|
|
- Support for Linux kernels up to 3.14. From Kernel 3.12 onwards OVS uses
|
2014-04-01 20:55:21 -07:00
|
|
|
tunnel API for GRE and VXLAN.
|
2014-03-24 19:23:08 -07:00
|
|
|
- Added DPDK support.
|
2014-03-30 12:26:55 +01:00

v2.1.0 - 19 Mar 2014
|
2013-08-28 16:18:05 -07:00
|
|
|
---------------------
|
2013-12-11 11:07:01 -08:00
|
|
|
- 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=[]
|
2013-11-13 11:19:56 -08:00
|
|
|
- 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.
|
2013-09-23 14:20:27 -07:00
|
|
|
- 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.
|
2013-10-11 13:23:29 +09:00
|
|
|
- OpenFlow:
|
|
|
|
|
* The OpenFlow 1.1+ "Write-Actions" instruction is now supported.
|
2013-11-06 16:12:34 -08:00
|
|
|
* 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.
|
2013-12-11 15:40:52 -08:00
|
|
|
* ovs-vswitchd now honors changes to the "ofport_request" column
|
|
|
|
|
in the Interface table by changing the port's OpenFlow port
|
|
|
|
|
number.
|
2015-02-01 13:50:40 -08:00
|
|
|
* The Open vSwitch software switch now supports OpenFlow groups.
|
2013-10-11 13:17:07 -07:00
|
|
|
- ovs-vswitchd.conf.db.5 man page will contain graphviz/dot
|
|
|
|
|
diagram only if graphviz package was installed at the build time.
|
2013-10-14 15:26:40 -07:00
|
|
|
- Support for Linux kernels up to 3.11
|
2013-10-21 14:37:34 -07:00
|
|
|
- ovs-dpctl:
|
|
|
|
|
The "show" command also displays mega flow mask stats.
|
2013-12-23 10:41:14 -08:00
|
|
|
- ovs-ofctl:
|
|
|
|
|
* New command "ofp-parse-pcap" to dump OpenFlow from PCAP files.
|
2013-10-11 16:24:41 -07:00
|
|
|
- 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.
|
2013-12-05 17:01:30 -08:00
|
|
|
- Added vlog option to export to a UDP syslog sink.
|
2013-03-27 14:26:21 -07:00
|
|
|
- ovsdb-client:
|
|
|
|
|
* The "monitor" command can now monitor all tables in a database,
|
|
|
|
|
instead of being limited to a single table.
|
2013-09-24 13:39:56 -07:00
|
|
|
- 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.
|
2014-02-06 16:04:05 -08:00
|
|
|
- Added IPv6 support for active and passive socket communications.

|
|
|
---------------------
|
2013-10-15 15:36:40 -07:00
|
|
|
- The ovs-vswitchd process is no longer single-threaded. Multiple
|
|
|
|
|
threads are now used to handle flow set up and asynchronous
|
|
|
|
|
logging.
|
2013-05-09 15:24:16 +03:00
|
|
|
- OpenFlow:
|
2013-07-08 14:48:05 -07:00
|
|
|
* Experimental support for OpenFlow 1.1 (in addition to 1.2 and
|
|
|
|
|
1.3, which had experimental support in 1.10).
|
2013-09-01 18:30:17 -07:00
|
|
|
* 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.
|
2013-05-09 15:24:16 +03:00
|
|
|
* New support for matching outer source and destination IP address
|
|
|
|
|
of tunneled packets, for tunnel ports configured with the newly
|
2013-07-23 15:03:52 -07:00
|
|
|
added "remote_ip=flow" and "local_ip=flow" options.
|
2013-08-06 12:57:16 -07:00
|
|
|
* Support for matching on metadata 'pkt_mark' for interacting with
|
|
|
|
|
other system components. On Linux this corresponds to the skb
|
|
|
|
|
mark.
|
2013-08-28 16:13:41 -07:00
|
|
|
* Support matching, rewriting SCTP ports
|
2013-07-08 13:36:06 -07:00
|
|
|
- The Interface table in the database has a new "ifindex" column to
|
|
|
|
|
report the interface's OS-assigned ifindex.
|
2013-05-28 11:44:21 -07:00
|
|
|
- New "check-oftest" Makefile target for running OFTest against Open
|
|
|
|
|
vSwitch. See README-OFTest for details.
|
2013-06-04 13:22:46 -07:00
|
|
|
- The flow eviction threshold has been moved to the Open_vSwitch table.
|
2013-06-24 08:38:22 -07:00
|
|
|
- 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").
|
2013-07-06 18:55:45 -07:00
|
|
|
- Added ovs-dev.py, a utility script helpful for Open vSwitch developers.
|
2013-08-02 11:38:51 -07:00
|
|
|
- Support for Linux kernels up to 3.10
|
2013-08-06 09:45:07 -07:00
|
|
|
- ovs-ofctl:
|
|
|
|
|
* New "ofp-parse" for printing OpenFlow messages read from a file.
|
2013-09-01 18:30:17 -07:00
|
|
|
* New commands for OpenFlow 1.1+ groups.
|
2013-08-21 13:49:04 -07:00
|
|
|
- Added configurable flow caching support to IPFIX exporter.
|
2013-09-03 09:54:51 -07:00
|
|
|
- Dropped support for Linux pre-2.6.32.
|
2013-09-17 14:36:41 -07:00
|
|
|
- Log file timestamps and ovsdb commit timestamps are now reported
|
|
|
|
|
with millisecond resolution. (Previous versions only reported
|
|
|
|
|
whole seconds.)

v1.11.0 - 28 Aug 2013
|
2013-02-04 21:55:32 -08:00
|
|
|
---------------------
|
2013-05-20 17:48:49 -07:00
|
|
|
- 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.
|
2013-04-19 16:25:56 -07:00
|
|
|
- The "tutorial" directory contains a new tutorial for some advanced
|
|
|
|
|
Open vSwitch features.
|
2013-02-04 18:28:57 -08:00
|
|
|
- Stable bond mode has been removed.
|
2013-02-04 18:45:54 -08:00
|
|
|
- The autopath action has been removed.
|
2013-02-21 21:52:04 -08:00
|
|
|
- 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.
|
2013-03-06 16:08:23 +09:00
|
|
|
- OpenFlow:
|
2013-03-06 16:08:12 +09:00
|
|
|
* The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow
|
|
|
|
|
1.1 and later are now implemented.
|
2013-03-05 16:27:55 -08:00
|
|
|
* New "stack" extension for use in actions, to push and pop from
|
|
|
|
|
NXM fields.
|
2013-05-08 11:03:06 -07:00
|
|
|
* 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.)
|
2013-03-15 13:47:53 -07:00
|
|
|
- ovs-dpctl:
|
|
|
|
|
* New debugging commands "add-flow", "mod-flow", "del-flow".
|
2013-08-03 12:23:14 -07:00
|
|
|
* "dump-flows" now has a -m option to increase output verbosity.
|
2013-05-14 18:24:43 -07:00
|
|
|
- In dpif-based bridges, cache action translations, which can improve
|
|
|
|
|
flow set up performance by 80% with a complicated flow table.
|
2013-04-04 10:42:47 -07:00
|
|
|
- New syslog format, prefixed with "ovs|", to be easier to filter.
|
2013-04-12 12:58:27 -07:00
|
|
|
- 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.
|
2013-05-15 14:31:06 -07:00
|
|
|
- New CFM demand mode which uses data traffic to indicate interface
|
|
|
|
|
liveness.
|
2013-02-04 21:55:32 -08:00

v1.10.0 - 01 May 2013
|
2013-02-04 15:56:36 -08:00
|
|
|
---------------------
|
2013-01-17 10:32:30 -08:00
|
|
|
- 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).
|
2012-12-08 12:32:33 -08:00
|
|
|
- The maximum size of the MAC learning table is now configurable.
|
2013-01-04 18:34:26 -08:00
|
|
|
- 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.
|
2013-03-18 09:58:47 -07:00
|
|
|
- ovs-vsctl:
|
|
|
|
|
* Previously ovs-vsctl would retry connecting to the database forever,
|
|
|
|
|
causing it to hang if ovsdb-server was not running. Now, ovs-vsctl
|
|
|
|
|
only tries once by default (use --retry to try forever). This change
|
|
|
|
|
means that you may want to remove uses of --timeout to avoid hangs
|
|
|
|
|
in ovs-vsctl calls.
|
|
|
|
|
* Many "ovs-vsctl" database commands now accept an --if-exists option.
|
|
|
|
|
Please refer to the ovs-vsctl manpage for details.
|
2013-02-04 14:13:25 -08:00
|
|
|
- OpenFlow:
|
2013-02-04 14:28:05 -08:00
|
|
|
- Experimental support for newer versions of OpenFlow. See
|
|
|
|
|
the "What versions of OpenFlow does Open vSwitch support?"
|
|
|
|
|
question in the FAQ for more details.
|
2013-02-04 14:13:25 -08:00
|
|
|
- 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.
|
2013-03-08 10:54:13 -08:00
|
|
|
- The NXM flow_removed message now reports the OpenFlow table ID
|
|
|
|
|
from which the flow was removed.
|
2013-02-04 21:45:29 -08:00
|
|
|
- Tunneling:
|
|
|
|
|
- New support for the VXLAN tunnel protocol (see the IETF draft here:
|
2013-02-24 18:58:03 -08:00
|
|
|
http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03).
|
2013-02-04 21:45:29 -08:00
|
|
|
- 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.
|
2013-03-11 16:00:17 -07:00
|
|
|
- CAPWAP tunneling support removed.
|
|
|
|
|
- Tunnels with multicast destination ports are no longer supported.
|
2013-02-04 14:13:25 -08:00
|
|
|
- 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.
|
2013-01-08 15:29:44 -08:00
|
|
|
- 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.
|
2013-02-04 21:45:29 -08:00
|
|
|
- Patch ports no longer require kernel support, so they now work
|
|
|
|
|
with FreeBSD and the kernel module built into Linux 3.3 and later.
|
2013-04-22 10:01:14 -07:00
|
|
|
- New "sample" action.
|
2012-11-05 11:05:18 -08:00

v1.9.0 - 26 Feb 2013
|
|
|
|
|
------------------------
|
2012-11-13 19:19:36 +02:00
|
|
|
- Datapath:
|
|
|
|
|
- Support for ipv6 set action.
|
|
|
|
|
- SKB mark matching and setting.
|
2013-01-16 11:19:21 +00:00
|
|
|
- support for Linux kernels up to 3.8
|
2012-07-25 22:51:05 +02:00
|
|
|
- FreeBSD is now a supported platform, thanks to code contributions from
|
|
|
|
|
Gaetano Catalli, Ed Maste, and Giuseppe Lettieri.
|
2012-07-18 23:50:03 -07:00
|
|
|
- ovs-bugtool: New --ovs option to report only OVS related information.
|
2012-07-18 10:30:47 -07:00
|
|
|
- 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.
|
2012-07-18 12:02:19 +09:00
|
|
|
- OpenFlow:
|
2012-07-19 09:21:49 -07:00
|
|
|
- Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL
|
|
|
|
|
fields in IPv6 neighbor discovery messages, and IPv6 flow label.
|
2012-10-19 02:37:37 +09:00
|
|
|
- Adds support for writing to the metadata field for a flow.
|
2013-02-04 21:45:29 -08:00
|
|
|
- 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.
|
2012-09-20 08:40:29 -07:00
|
|
|
- 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).
|
2012-08-03 11:56:33 -07:00
|
|
|
- ovs-dpctl:
|
2012-07-27 23:59:23 -07:00
|
|
|
- Support requesting the port number with the "port_no" option in
|
|
|
|
|
the "add-if" command.
|
2012-08-03 11:56:33 -07:00
|
|
|
- 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.)
|
2012-09-05 10:35:20 -07:00
|
|
|
- ovsdb-server now enforces the immutability of immutable columns. This
|
|
|
|
|
was not enforced in earlier versions due to an oversight.
|
2012-09-26 09:57:28 -07:00
|
|
|
- The following features are now deprecated. They will be removed no
|
|
|
|
|
earlier than February 2013. Please email dev@openvswitch.org with
|
|
|
|
|
concerns.
|
2012-12-27 13:30:59 -08:00
|
|
|
- Bridge compatibility.
|
2012-09-26 09:57:28 -07:00
|
|
|
- Stable bond mode.
|
|
|
|
|
- The autopath action.
|
|
|
|
|
- Interface type "null".
|
|
|
|
|
- Numeric values for reserved ports (see "ovs-ofctl" note above).
|
2012-10-29 18:12:03 +02:00
|
|
|
- Tunnel Path MTU Discovery.
|
2012-11-05 13:40:17 -08:00
|
|
|
- CAPWAP tunnel support.
|
2012-11-05 11:05:18 -08:00
|
|
|
- The data in the RARP packets can now be matched in the same way as the
|
|
|
|
|
data in ARP packets.
|

|
|
|
- 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.
|
2012-06-28 15:52:40 -07:00
|
|
|
- ovs-l3ping:
|
|
|
|
|
- A new test utility that can create L3 tunnel between two Open
|
|
|
|
|
vSwitches and detect connectivity issues.
|
2012-05-24 14:17:55 -07:00
|
|
|
- ovs-ofctl:
|
2012-07-12 13:32:47 -07:00

|
- "mod-port" command can now control all OpenFlow config flags.
|
2012-05-22 22:06:03 -07:00
|
|
|
- OpenFlow:
|
2012-05-22 22:49:31 -07:00
|
|
|
- Allow general bitwise masking for IPv4 and IPv6 addresses in
|
|
|
|
|
IPv4, IPv6, and ARP packets. (Previously, only CIDR masks
|
2012-05-22 22:06:03 -07:00
|
|
|
were allowed.)
|
|
|
|
|
- Allow support for arbitrary Ethernet masks. (Previously, only
|
|
|
|
|
the multicast bit in the destination address could be individually
|
|
|
|
|
masked.)
|
2012-06-27 01:09:44 +12:00
|
|
|
- New field OXM_OF_METADATA, to align with OpenFlow 1.1.
|
2012-06-11 11:23:06 -07:00
|
|
|
- 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.)
|
2012-07-12 14:18:05 -07:00
|
|
|
- New "flow monitor" feature to allow controllers to be notified of
|
|
|
|
|
flow table changes as they happen.
|
2012-06-06 15:22:52 -07:00
|
|
|
- Additional protocols are not mirrored and dropped when forward-bpdu is
|
|
|
|
|
false. For a full list, see the ovs-vswitchd.conf.db man page.
|
2012-06-07 15:27:22 -07:00
|
|
|
- Open vSwitch now sends RARP packets in situations where it previously
|
|
|
|
|
sent a custom protocol, making it consistent with behavior of QEMU and
|
|
|
|
|
VMware.
|
2012-07-02 04:32:44 -07:00
|
|
|
- All Open vSwitch programs and log files now show timestamps in UTC,
|
|
|
|
|
instead the local timezone, by default.

|
2012-02-24 10:32:36 -08:00
|
|
|
------------------------
|
2012-03-09 09:55:45 -08:00
|
|
|
- kernel modules are renamed. openvswitch_mod.ko is now
|
|
|
|
|
openvswitch.ko and brcompat_mod.ko is now brcompat.ko.
|
2012-03-08 14:44:54 -08:00
|
|
|
- Increased the number of NXM registers to 8.
|
2012-07-23 00:33:32 -07:00
|
|
|
- Added ability to configure DSCP setting for manager and controller
|
2012-03-10 15:58:10 -08:00
|
|
|
connections. By default, these connections have a DSCP value of
|
|
|
|
|
Internetwork Control (0xc0).
|
2012-04-05 14:30:23 -07:00
|
|
|
- Added the granular link health statistics, 'cfm_health', to an
|
|
|
|
|
interface.
|
2012-04-25 15:48:40 -07:00
|
|
|
- OpenFlow:
|
|
|
|
|
- Added support to mask nd_target for ICMPv6 neighbor discovery flows.
|
2012-05-04 14:42:04 -07:00
|
|
|
- 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.
|
2012-03-29 19:03:08 -07:00
|
|
|
- ovs-test:
|
|
|
|
|
- Added support for spawning ovs-test server from the client.
|
|
|
|
|
- Now ovs-test is able to automatically create test bridges and ports.
|
2012-04-05 10:24:56 -07:00
|
|
|
- "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows.
|
2012-07-23 00:33:32 -07:00
|
|
|
- Tripled flow setup performance.
|
2012-04-20 14:09:30 -07:00
|
|
|
- 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.
|
2012-02-24 10:32:36 -08:00

|
|
|
|
|
*** Internal only release ***
|
2012-01-11 17:23:38 -08:00
|
|
|
- bonding
|
2011-11-28 13:54:08 -08:00
|
|
|
- LACP bonds no longer fall back to balance-slb when negotiations fail.
|
|
|
|
|
Instead they drop traffic.
|
2012-01-11 17:23:38 -08:00
|
|
|
- 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).
|
2012-01-25 17:41:44 -08:00
|
|
|
- Load balancing can be disabled by setting the bond-rebalance-interval
|
|
|
|
|
to zero.
|
2012-01-27 17:16:05 -08:00
|
|
|
- OpenFlow:
|
|
|
|
|
- Added support for bitwise matching on TCP and UDP ports.
|
|
|
|
|
See ovs-ofctl(8) for more information.
|
2012-02-09 14:06:35 -08:00
|
|
|
- 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.
|
2012-02-15 10:37:03 -08:00
|
|
|
- New "fin_timeout" action.
|
|
|
|
|
- Added "fin_timeout" support to "learn" action.
|
2012-02-09 14:17:33 -08:00
|
|
|
- New Nicira action NXAST_CONTROLLER that offers additional features
|
|
|
|
|
over output to OFPP_CONTROLLER.
|
2012-02-16 16:33:14 -08:00
|
|
|
- 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.
|
2012-02-08 15:29:15 -08:00
|
|
|
- Logging:
|
|
|
|
|
- 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.
|
|
|
|
|
- The syntax of commands and options to set log levels was simplified,
|
|
|

broken device drivers are no longer in widespread use, we will
|
|
|
|
|
delete this feature.) See ovs-vswitchd.conf.db(5) for more
|
|
|
|
|
information.

|
now be properly mirrored for any flows, regardless of their
|
|
|
|
|
actions.
|
2011-11-20 15:12:36 -08:00

- bonding:
|
|
|
|
|
- Post 1.4.*, OVS will be changing the default bond mode from balance-slb
|
|
|
|
|
to active-backup. SLB bonds carry significant risks with them
|
|
|
|
|
(documented vswitchd/INTERNALS) which we want to prevent unsuspecting
|
|
|
|
|
users from running into. Users are advised to update any scripts or
|
|
|
|
|
configuration which may be negatively impacted by explicitly setting
|
|
|
|
|
the bond mode which they want to use.

|
2011-08-09 09:24:18 -07:00
|
|
|
- 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.
|
2011-10-14 09:48:17 -07:00
|
|
|
- Add support for 802.1D spanning tree (STP).
|
Implement new fragment handling policy.
Until now, OVS has handled IP fragments more awkwardly than necessary. It
has not been possible to match on L4 headers, even in fragments with offset
0 where they are actually present. This means that there was no way to
implement ACLs that treat, say, different TCP ports differently, on
fragmented traffic; instead, all decisions for fragment forwarding had to
be made on the basis of L2 and L3 headers alone.
This commit improves the situation significantly. It is still not possible
to match on L4 headers in fragments with nonzero offset, because that
information is simply not present in such fragments, but this commit adds
the ability to match on L4 headers for fragments with zero offset. This
means that it becomes possible to implement ACLs that drop such "first
fragments" on the basis of L4 headers. In practice, that effectively
blocks even fragmented traffic on an L4 basis, because the receiving IP
stack cannot reassemble a full packet when the first fragment is missing.
This commit works by adding a new "fragment type" to the kernel flow match
and making it available through OpenFlow as a new NXM field named
NXM_NX_IP_FRAG. Because OpenFlow 1.0 explicitly says that the L4 fields
are always 0 for IP fragments, it adds a new OpenFlow fragment handling
mode that fills in the L4 fields for "first fragments". It also enhances
ovs-ofctl to allow users to configure this new fragment handling mode and
to parse the new field.

2011-10-19 21:33:44 -07:00
|
|
|
- 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.
|
2011-12-21 11:01:45 -08:00
|
|
|
- CAPWAP tunneling now supports an extension to transport a 64-bit key.
|
|

|
|
|
standards-based implementations.
|
2011-09-16 15:23:37 -07:00
|
|
|
- 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.
|
2011-09-23 17:03:03 -07:00
|
|
|
- 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".
|
2011-10-24 10:36:01 -07:00
|
|
|
- test-openflowd has been removed. Please use ovs-vswitchd instead.
|

- 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.
|
2011-07-27 14:58:10 -07:00
|
|
|
- ovs-ofctl:

|
|
|
- New "comment" command to add remark that explains intentions.
|
2011-06-08 09:15:38 -07:00
|

|
- ovs-brcompatd has been rewritten to fix long-standing bugs.
|
2011-06-07 09:40:53 -07:00
|
|
|
- ovs-openflowd has been renamed test-openflowd and moved into the
|
|
|
|
|
tests directory. Its presence confused too many users. Please
|
|
|
|
|
use ovs-vswitchd instead.
|
2011-08-02 23:15:30 -07:00
|
|
|
- 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.
|
2011-06-22 11:07:33 -07:00

|
|
|
|
|
names will be removed after the next release, so please update
|
|
|
|
|
your scripts.
|
2011-06-23 17:10:00 -07:00
|
|
|
- The "-2.6" suffix has been dropped from the datapath/linux-2.6 and

|
|
|
- There is no default controller anymore. Each bridge must have its
|
|
|
|
|
controller individually specified.
|
|
|
|
|
- The "fail-mode" is now a property of a Bridge instead of a Controller.
|
|
|
|
|
- New versioning and checksum features.
|
|
|
|
|
- New Managers table and manager_options column in Open_vSwitch table
|
|
|
|
|
for specifying managers. The old "managers" column in the
|
|
|
|
|
Open_vSwitch table has been removed.
|
|
|
|
|
- Many "name" columns are now immutable.
|
|
|
|
|
- Feature removals:
|
|
|
|
|
- Dropped support for XenServer pre-5.6.100.
|
|
|
|
|
- Dropped support for Linux pre-2.6.18.
|
|
|
|
|
- Dropped controller discovery support.
|
|
|
|
|
- Dropped "ovs-ofctl status" and the OpenFlow extension that it used.
|
|
|
|
|
Statistics reporting in the database is a rough equivalent.
|
|
|
|
|
- Dropped the "corekeeper" package (now separate, at
|
|
|
|
|
http://openvswitch.org/cgi-bin/gitweb.cgi?p=corekeeper).
