Cryptographic Offloading To DPU/XPU PCI Cards Using Virtio-Crypto and DPDK Ethdev as Transport - Akhil Goyal & Anoob Joseph, Marvell

Wednesday May 13, 2026 09:15 - 09:45 CEST

Rum 17+18 - Floor 3

In this session, we will explore a use case where PCI endpoint card is utilized to offload cryptographic operations from the host machine. The buffers for these operations are transferred to the PCI card via the virtio/ethernet interface between the host and the endpoint over PCI. We will discuss two distinct approaches to manage crypto operations.

Approach 1: Standard Virtio-Crypto Interface - DPDK/kernel virtio-crypto device is used to establish crypto sessions and transmit data across the PCI endpoint. The endpoint performs cryptographic operations and returns processed data to the virtio-crypto device. The application running on the endpoint translates the virtio-crypto sessions and processes the data using the DPDK crypto device on the endpoint, subsequently sending the processed data back to the host.
Approach 2: LiquidCrypto - Due to limited virtio-crypto offload capabilities, second approach is proposed. This method utilizes the DPDK ethernet SDP interface between the host and endpoint for fast path transport and the kernel SDP interface for slow path and management of the PCI card. The sample applications and the interface library are open-source and available on GitHub.

PQC Integration in DPDK: OpenSSL PMD Implementation and Future Offload Roadmap - Gowrishankar Muthukrishnan & Akhil Goyal, Marvell

Wednesday May 13, 2026 10:05 - 10:15 CEST

Rum 17+18 - Floor 3

Post Quantum Cryptography (PQC) requires seamless integration into modern packet frameworks. This work introduces post-quantum cryptography (PQC) support in the Data Plane Development Kit (DPDK) through the OpenSSL Poll Mode Driver (PMD), providing developers with a practical entry point to experiment with PQC primitives using the familiar cryptodev API. The OpenSSL PMD implementation serves as a reference design, demonstrating how PQC algorithms such as key encapsulation and digital signatures can be exposed consistently to applications with minimal changes. For developers, this enables immediate validation, benchmarking, and integration of PQC workloads in software, while establishing a clear API model for future extensions. The long-term vision is for hardware crypto accelerators—including Octeon CNXK and VirtIO crypto drivers—to adopt this reference approach, ensuring interoperability and contributing back to the community. By aligning software and hardware PMDs around a unified PQC API, DPDK fosters a collaborative ecosystem where developers, vendors, and operators can build scalable, quantum resilient applications such as VPNs, TLS termination, IPsec gateways, and 5G cores.

DPDK Integration for DPI: Practical Trade-offs Between Throughput, Portability, and Operations - Harald Bunke, ipoque GmbH, a Rohde & Schwarz company

Wednesday May 13, 2026 10:20 - 10:30 CEST

Rum 17+18 - Floor 3

DPDK is used as the packet-ingest layer for a traffic monitoring system feeding an internal DPI engine.
Today, throughput is maximized by tuning for a specific server/NIC/OS combination, but this reduces portability and increases operational effort.

This lightning talk discusses the throughput impact observed when moving toward a more “generic” deployment.
Results are presented for: (1) optimized (“native”) vs portable (“generic”) builds, (2) CPU isolation, (3) hugepage configuration and (4) PMD/driver configuration.

Beyond Throughput: Exploring the Ambiguities and Limits of rte_flow Offloading - Pavlina Patova, DynaNIC Semiconductors

Wednesday May 13, 2026 10:55 - 11:25 CEST

Rum 17+18 - Floor 3

As network speeds increase, relying on hardware offloading via rte_flow becomes essential. However, the implementation of these APIs varies significantly across vendors. This talk shares findings from an ongoing exploration of NIC performance (NVIDIA, Intel or DYNANIC), with a primary focus on the capabilities and limitations of hardware-offloaded packet filtering using the DPDK rte_flow API. While standard throughput metrics are important, this session moves beyond basic performance to explore the behavior of NICs under stress and in ambiguous scenarios that are often overlooked in standard datasheets.

AI-Assisted Formal Verification of the DPDK eBPF Verifier - Marat Khalili & Claudia Cauli, Huawei Ireland Research Center

Wednesday May 13, 2026 11:30 - 12:00 CEST

Rum 17+18 - Floor 3

eBPF support was added to DPDK in 2018, enabling users to execute custom byte-code to extend application functionality without rebuilding or restarting. Our Data-Plane team aims to make eBPF a first-class citizen in HC data-plane appliances. However, safe usage requires ensuring custom programs won't crash the application. The current DPDK eBPF verifier lacks essential features and isn't as robust as the Linux kernel version. This presentation covers two aspects:
- eBPF Usage in Data-Plane Appliances: Current and planned uses, missing DPDK eBPF functionality, and requirements for wider community adoption.
- Verifying the Verifier: We applied bounded model checking and deductive verification to verify the BPF validator's correctness. We uncovered multiple previously unknown bugs across distinct classes. For each bug, we produced counterexamples, verified fixes, and machine-checked proofs. Using an AI assistant, we formally verified the validator in days. We'll share practical lessons for applying AI-assisted formal verification to DPDK subsystems.

Packet Capture Tool Based on eBPF for DPDK - Tengteng Yang, ByteDance

Wednesday May 13, 2026 12:05 - 12:15 CEST

Rum 17+18 - Floor 3

In the field of high-performance networking, traditional packet capture tools like tcpdump are facing a massive blind spot in observability. tcpdump relies heavily on the kernel protocol stack, whereas modern high-performance applications widely adopt DPDK technology. In DPDK, packets flow directly between userspace drivers and applications via mbuf, completely bypassing the kernel.

To address these pain points, we have introduced an internal open-source network observability tool — netcap.

Netcap not only inherits the ability to trace kernel skbs but also achieves breakthrough support for DPDK mbufs:
- Deep Userspace Introspection: It can delve directly into userspace memory, non-intrusively capturing and parsing mbuf data flowing through critical DPDK processing functions.
- Zero Learning Curve: It perfectly supports tcpdump filter syntax (BPF filters), allowing developers to precisely capture the mbuf traffic they care about, just like using tcpdump.

The emergence of netcap effectively fills the gap in "mbuf observability" within high-performance network development, making black-box debugging of DPDK applications a thing of the past.

Multithreading on Eventdev - Mattias Rönnblom, Ericsson

Wednesday May 13, 2026 12:35 - 12:45 CEST

Rum 17+18 - Floor 3

Events (jobs) in Eventdev are non-preemptive, and thus must be relatively short run time.

One way to deal with this issue is to split large jobs into multiple events.

For legacy code, originally design for POSIX threads, such an exercise may be costly. Also, for certain domains, being able to retain the stack between invocations (events) may results in a simpler program.

This talk briefly introduce this topic and discuss an Ericsson prototype coroutine library running on top of Eventdev, allowing for a code written for a thread-like, cooperative multi-tasking programming model to coexist with native event-driven programs running on the same DPDK lcores, making the coroutine library in combination the event device a task/thread scheduler.

The Little Extras in DPDK - Bruce Richardson, Intel Corporation

Wednesday May 13, 2026 13:55 - 14:25 CEST

Rum 17+18 - Floor 3

As a long-time DPDK developer, I am more used to working on code WITHIN DPDK rather than writing apps USING DPDK. On the odd occasion, when I do need to create an end-user app using DPDK, there are a number of the additional little libraries and tools in DPDK that I reach for to improve the DPDK app development and debug process. These include the cmdline library (including using the new script for cmdline generation), configfile library, telemetry support, and others. While most of these are not likely to be new to many developers, the content here may prove helpful to anyone starting out with green-field DPDK development, or putting together quick apps for packet processing using DPDK.

Yelled at by LLMs: Putting a Megaphone To AI Models in DPDK CI - Aaron Conole, Red Hat & Stephen Hemminger, Independent

Wednesday May 13, 2026 15:55 - 16:25 CEST

Rum 17+18 - Floor 3

Over the past year, the Tech Board has been reviewing how to integrate LLMs into the CI workflow to enact an assisted review cycle for patches. This work has looked at various aspects of adding an AI review assistant to the process that can help maintainers and developers spot difficult to reach issues. The results of the trial-and-error testing have lead to a new AI assistant that helps to review patches and series.
In this talk, we'll cover the various roads we took for analysis, AI review infrastructure that lives in the tree, the policy around getting an LLM review of patches, and future work.

Develop With Confidence: Integrating the DPDK Test Suite With Your Development Workflow - Patrick Robb, DTS Maintainer

Wednesday May 13, 2026 16:30 - 17:00 CEST

Rum 17+18 - Floor 3

Currently, the standard development workflow for DPDK goes something like this: A developer wants to add a new feature or resolve a bug in DPDK, so they write a patch, run the DPDK unit tests against it, and then if those are passing, send it off to the mailing list, where it will get picked up by CI labs that run end to end testing on real hardware using the DPDK Test Suite. Although this solution works fairly well, DPDK developers may also gain some valuable speed and confidence by directly integrating the DPDK Test Suite into their local development workflow. So, I will “demo” the following sequence. First apply a patch to DPDK which either resolves or breaks some DPDK functionality. Then, pass this new DPDK source into the DPDK Test Suite, executing a testcase/testcases on a minimal DTS setup. Then, overview the results produced by DTS, and highlight how the patch applied in step 1 resolved/broke functionality tracked by the testcase/testcases being run. Specifically, I will demonstrate this workflow through the new Flow Offload Testsuite that is arriving to DPDK in DPDK version 26.03.
