Release Highlights

There are many excellent new features in this release, however a few of them deserve a special mention.

Linux Control Plane Plugin (linux-cp)

One of the more significant new features included in this release is a linux control plane (linux-cp) plugin. It enables the near-seamless integration of VPP with the host control plane, by mirroring the VPP interfaces into a TUN or TAP device created in the linux kernel. All of the punted packets received on the VPP interface will be sent to the linux counterpart, and in the reverse direction, packets sent by linux kernel will be transmitted out the VPP interface. This plugin lays the foundation for the much easier integration of external software with VPP.

Performance Monitor Plugin (perfmon)

Another interesting feature is the performance monitor (perfmon) plugin. It allows collection of detailed low-level CPU statistics on a per-node basis. It provides a useful advanced troubleshooting tool, should you encounter that a specific node's performance is not on par with what it should be. Note, that the correct functioning of this plugin may require changing the /proc/sys/kernel/perf_event_paranoid setting to enable access to the performance counters.

API CRC Substitution Table Removal

And finally a clarification, not a feature per se. Some messages in the API changes table for this release have a new marking: "message CRC32 fix". The history of this issue goes back to summer of 2020, when it was discovered that for a considerable amount of time (several months) the calculation of the CRC of API messages was incorrect. Specifically, all but the first user-defined types in the message failed to be included in the CRC calculation. In plain words, this means that one might end up with a situation where client and VPP layout of message in memory could be quite different.

At the time of discovery, there were no API changes that were affected by that bug. However, simply fixing it meant the CRC of about half of the VPP API messages would be altered for no reason which would result in a significant amount of pain to the consumers of VPP. A message CRC is just an opague number for anyone using it, and the only property of it for the user is that the messages with the same value of CRC have the same layout on the wire with a sufficiently high certainty.

Therefore a fix (9f84e70c6) was merged that also contained a "band-aid" to avoid this pain. In addition to fixing the CRC generation algorithm, the fix captured the "new" CRC values for those messages that had their CRCs arbitrarily changed by this fix and created a substituion table with [message name, new CRC, old CRC] triplets. For a given message, if the CRC matched the recorded new value, the code would substitute it with the old value, thus trading in a reduction in collision resistance (two values of CRC out of 2^32 space) for not forcing users to adapt to several hundred of messages which changed the CRCs.

This band-aid also had the property that whenever a message did change the definition, it would automatically get a "correct" calculation of CRC32 and no longer use the slot in the table. The table naturally shrinks over time, thus allowing a painless transition, while also preserving the integrity check for the affected messages. If any fields changed, the CRC would no longer match the "new" value thus no substitution would be made. Since the choice of CRC32 is just an implementation detail which is supposed to be opaque to the user, the band-aid was deemed a reasonable approach to avoid a major burden on VPP consumers.

However, in practice this solution was not accepted well. After a notification period, the API CRC Substitution table was removed by the patch (da1b76aa8). Thus all of the API CRC changes that did not happen in 9f84e70c6, happened in da1b76aa8. Hopefully the notification of these changes has reduced the inconvenience. VPP users are asked to not rely on any other property of the message CRC other than changes to its value when the message layout changes.

@page release_notes_2101 Release notes for VPP 21.01

Release Highlights

The FD.io VPP 20.09 release comprises more than 562 commits since the previous release, including 274 fixes. Notable changes in this release were the Virtio driver adding packet buffering on the transmit path to handle slow back-ends which often have jitter and delays in free'ing buffers, and also adding support for Virtio 1.1 packed rings. FD.io VPP IPSEC added support for multi-point on IPSec interfaces, brings the meshed benefits of IP to IPSec tunnels. The FD.io VPP Cloud NAT (CNAT), added support source NAT ICMP and DHCP. The FD.io VPP FIB added support for source address selection (SAS) and flow hashing on the inner packets. Finally the FD.io VPP Perfmon plugin has been substantially rewritten, to support measuring bundles of counters, and reporting statistics per graph node.

Reflecting the API change policy introduced in the 20.09, please review the following sections below:

Newly deprecated API messages: please note that if you are using a deprecated message, they will soon be removed in a subsequent release. Collaborate with the feature maintainer on the best approach to mitigate.
In-progress API messages: They are work-in-progress, and are not subject to the policy, and may change or even be removed at any time. Please collaborate with the feature maintainer on plans to productize the message before using in any product. In-progress APIs must eventually become stable or be removed.

@page release_notes_2009 Release notes for VPP 20.09

More than 458 commits since the previous release, including 266 fixes.

Release Highlights

The FD.io VPP 20.09 release added a number of notable new features. In plugins, the I/O layer added support for the Linux AF_XDP interface with the AF_XDP plugin. New plugins where added supporting both the Wireguard security protocol and CNAT destination based address translation, and the existing IKEv2 plugin added support for NAT-T. In the cryptography layer, support was added for synchronous software crypto engines, enabling users to allocate dedicated crypto worker threads. The flow layer added support for steering IPSEC ESP/AH flows to worker threads. GRO support was added to the packet coalescing library.

This release introduces the new FD.io VPP API change policy to ensure backwards-compatibility. The policy will ensure seamless upgrades to new versions of FD.io VPP in future, provided no "in-progress" or deprecated APIs are in use. Enabling the FD.io community to enjoy the benefits of new releases, while minimizing the work involved in staying current.

If you dive into the implementation, you will note that policy in action. A number of modified API messages have had their original versions maintained to ensure compatibility.

Reflecting the new policy we added two new sections to the release notes describing:

Newly deprecated API messages: please note that if you are using a deprecated message, they will soon be removed in a subsequent release. Collaborate with the feature maintainer on the best approach to mitigate.
In-progress API messages: They are work-in-progress, and are not subject to the policy, and may change or even be removed at any time. Please collaborate with the feature maintainer on plans to productize the message before using in any product. In-progress APIs must eventually become stable or be removed.

Ongoing Work On More Semantic-Typed API

This release, like the 20.01, continues the journey on defining the semantic-based types instead of storage-based types within the API, so you may have noticed this in the API changes.

Some of the changes are related to the infrastructure, and may be bugfixes, they do not change the CRC of the message but affect the representation on the wire. One particular commit we want you to pay attention to, is b5c0d35f, which fixes the bug with the enum representation on the wire - before it, even the enums declared as u8 or u16 were represented as u32 in the API messages.

Another important commit we would like to call out explicitly as well is 7dd63e5c, which pinned the address_family and ip_proto enum types to be u8 instead of the default u32.

The above two commits will be primarily interesting for those who work with the low-level APIs on VPP - the API frameworks should make these under-the-hood changes transparent. However, we decided to call these out, given that for those affected these will be pretty important changes.

Another commit, that does not have the immediate impact at the moment, but that is poised to improve the user interaction with the API is 5c318c70. This adds the tooling and ability to implement a structured process, by which the API messages can evolve, while minimizing the impact to the API users.

@page release_notes_19081 Release notes for VPP 19.08.1

Exceptionally, this release has an API-changing fix introduced via https://gerrit.fd.io/r/#/c/vpp/+/21762/ - documented in VPP-1767. Given the exceptional nature of the change, also including the text here:

Bug: https://gerrit.fd.io/r/c/vpp/+/21492

Variable length strings were committed to VPP in 413f4a5b. The VPP server side of the API does not use a wire encoder/decoder. It maps a C struct directly onto on-the-wire API messages. The client side C language binding is the same, while other language bindings have their own encoder/decoders.

Multiple strings alone or combined with other variable length types turned out to be error prone to manually implement on the VPP side, and not supported by VPP API (VAPI) very well at all.

To avoid having to rewrite VAPI significantly, and to mitigate the risk and error prone server side support of multiple variable length fields, this patch extends strings to have a fixed size (on the wire) and a variable flavour, as well as adding detection in the API compiler to detect multiple variable length fields in a message (or type).

Given that this change breaks the commitment to binary API compatibility, normally present in point builds, ALL 19.08 build artifacts are being deferred.

This means the artifacts for the VPP 19.08.1 will be installed in the release repository (packagecloud.io/fdio/release), then ALL 19.08 build artifacts will be moved into the deferred repository (packagecloud.io/fdio/deferred). The 19.08 artifacts will always be available for archive purposes in the deferred repository.

During the further testing by Networking-VPP team, they discovered another issue documented in VPP-1769 - which requires a CRC-affecting fix in https://gerrit.fd.io/r/#/c/vpp/+/22015/ - so the 19.08.1 will contain the fixes for both issues.

These two changes have resulted in the following 20 messages changing their signatures:

Features

Infrastructure

DPDK 18.02.1
- Complete rework of the dpdk-input node
- Display rx/tx burst function name in "show hardware detail"
- Improve buffer alloc perfomance
  - This is ~50% improvement in buffer alloc performance. For a 256 buffer allocation, it was ~10 clocks/buffer, now is < 5 clocks.
- Add per-numa page allocation info to 'show memory'
- Vectorized bihash_{48,40,24,16}_8 key compare
  - bihash_48_8 case:
    - Scalar code: 6 clocks
    - SSE4.2 code: 3 clocks
    - AVX2 code: 2.27 clocks
    - AVX512 code: 1.5 clocks
- Pollable Stats
  - Stats are now available to a client in a shared memory segment and in the form of a directory, allowing very high performance polling of stats without directly querying VPP.

VNET & Plugins

IGMP improvements
- Enable/Disable an interface for IGMP
- improve logging
- refactor common code

API changes

Python API: To avoid conflicts between VPP API messages names and the Python API binding function names, VPP API methods are put in a separate proxy object. https://gerrit.fd.io/r/#/c/5570/ The api methods are now referenced as: vpp_handle = VPP(jsonfiles) vpp_handle.connect(...) vpp = vpp_handle.api vpp.show_version() vpp_handle.disconnect()

For backwards compatibility VPP API methods are left in the main name space (VPP), but will be removed from 17.07.
- Python API: Change from cPython to CFFI.
create_loopback message to be replaced with create_loopback_instance create_loopback will be removed from 17.07. https://gerrit.fd.io/r/#/c/5572/
