0x1A: BoF, Your Fu is Better Than Mine, 3.0!
by Jamal Hadi Salim 15 Jun '26

15 Jun '26

PJ is back with the ever-popular, often-requested, BoF v3! PJ says: This is a safe space, a judgement-free zone. Come with your cool hacks, workflows, test harnesses, whatever. This is a place where all of us who have worked in this space for decades or months can converge, and share knowledge of how we work in this space better. If you’re interested, just bring a short demo. Bonus points this year if we can ride the AI train, and bring a Skill or share effective prompts. Or a simple benchmark that you can show why it’s important to you. No judgements, just pure sharing. Often people in the audience get encouraged by who is presenting, and spontaneously decide to present something of theirs. That’s the spirit of the OG BoF. Let’s do this again, again. cheers, jamal

0x1A: BoF, Could an IPv6-Only Kernel Be a Reality? An Architectural and Performance Evaluation
by Jamal Hadi Salim 15 Jun '26

15 Jun '26

Fernando Fernandez Mancera chairs this BoF which explores the feasibility of a standalone IPv6 Linux kernel, decoupling it from its current mandatory dependency on the IPv4 stack. The BoF presenters will share an experimental implementation, analyze its impact on architecture and performance, and seek community feedback on an upcoming RFC to identify potential blockers for upstream integration. cheers, jamal

0x1A: BoF, Need for Bidirectional Event Handlers in Auxiliary Bus
by Jamal Hadi Salim 15 Jun '26

15 Jun '26

The auxiliary bus enables clean PCI device partitioning into multiple drivers but lacks a native signaling mechanism for bi-directional event notifications. Dave Ertman says this restricts communication to a passive model where the parent merely exposes data for the child to consume, hindering real-time coordination for critical events like resets, configuration changes, or cross-driver resource management. Dave has a proposal to address these challenges but there are open questions. Come and interact and provide your feedback.

0x1A: Tutorial, Making Time Uncertainty a First-Class Concept in Linux Timing
by Jamal Hadi Salim 14 Jun '26

14 Jun '26

Maciek Machnikowski continues his tradition of teaching us about Time. In this session, Maciek reframes timestamps as intervals with quantified uncertainty rather than precise points, arguing that explicit uncertainty windows let applications reason about temporal correctness without hidden accuracy assumptions. He discusses sources of uncertainty such as clock sync offsets, network delay jitter, hardware timestamping limitations, and kernel-to-userspace transfer paths. Ignoring these, argues Maciek, causes errors in ordering, causality detection, and compliance checks. He will describe a time-uncertainty daemon sample and discuss Linux kernel API gaps. Come and grow your knowledge with a real human maestro! More details: https://netdevconf.info/0x1A/sessions/tutorial/making-time-uncertainty-a-fi… cheers, jamal

0x1A: Workshop, What's next for the PSP Security Protocol
by Jamal Hadi Salim 12 Jun '26

12 Jun '26

Willem de Bruijn will chair a workshop on PSP Security Protocol. PSP is an inline cryptography protocol optimized for large-scale datacenter deployments. It scales to high performance and high connection count. PSP is supported by network devices from Broadcom, Intel, Nvidia and others and by the Linux kernel as of v6.18. Current hardware implements the initial PSP Architecture Spec. In this workshop Willem will lead a discussion on candidate extensions for the next version of PSP, such as confidential compute and multi-host support. Future directions for the Linux kernel PSP stack and support infra such as packetdrill test coverage will be covered. cheers, jamal
