AI for Kernel Engineers - Sasha Levin, NVIDIA

Monday June 23, 2025 11:20am - 12:00pm MDT

Bluebird Ballroom 2D

Beyond the hype, AI is already impacting Linux kernel engineering workflows. This talk presents concrete examples from real-world applications in Linux kernel LTS maintenance and CVE assignment processes. We'll examine where AI tools have meaningfully improved development processes and where they fall short.
Drawing from hands-on experience, we'll demonstrate how AI assists in analyzing patches for LTS kernel trees and streamlines vulnerability classification workflows. We'll share specific metrics showing both successes and limitations, focusing on practical applications rather than theoretical possibilities. We'll also explore emerging opportunities where AI could enhance kernel development while maintaining high engineering standards.
This technical session provides kernel developers, maintainers, and engineering leaders with actionable insights for integrating AI tools into their workflows while preserving the rigor of kernel development practices.

Speakers

Navigating the Sea of CVEs: Securing Your Linux Distributions - Jess Lowe & Holly Gong, Google

Monday June 23, 2025 2:25pm - 3:05pm MDT

Bluebird Ballroom 2D

Are you drowning in a sea of vulnerability advisories, wondering why patching one thing doesn't fix everything? Despite a shared origin, a CVE's impact diverges significantly across Linux distributions. Consequently, a fix at the source does not automatically translate to comprehensive protection downstream. Each distribution requires independent patching, leading to a complex web of security advisories stemming from a single flaw.

In this talk, you'll learn how OSV tools can help you navigate this sea of advisories. We'll explore the root causes of advisory proliferation in Linux and demonstrate how OSV.dev aggregates and cross-references vulnerability data at scale to provide a more complete picture. You'll also see how OSV-Scanner accurately identifies vulnerabilities in your Linux systems, considering distribution-specific nuances and offering actionable guidance. By the end of this session, you'll be equipped with the knowledge and tools to patch smarter and secure your Linux infrastructure more effectively.

Intentrace, Making Strace More Human Using Rust - Mohammad Khalid, Independent

Monday June 23, 2025 3:35pm - 3:45pm MDT

Bluebird Ballroom 2D

Understand how all binaries interact with the linux kernel, how the linux kernel sees userspace code, how it expects it to behave, and how you, an author of such programs, should in response interact with it. intentrace is a rewrite of strace in Rust. currently in Beta.

Improve Load Balancing With Machine Learning Techniques Based on the Sched_ext Framework - Jim Huang, National Cheng Kung University

Monday June 23, 2025 4:30pm - 5:10pm MDT

Bluebird Ballroom 2D

This talk presents a method to enhance CPU scheduling by leveraging machine learning (ML) to extract the key features necessary for task migration, allowing for dynamic and stable optimization of workloads in scenarios prone to CPU imbalance. The approach is built on the sched_ext framework, which integrates eBPF to support user-defined scheduling policies within the Linux kernel.

While conventional approaches maximize CPU utilization, they often overlook contention for lower-level hardware resources, leading to performance bottlenecks -- particularly in compute-intensive servers. By using an ML-based, resource-aware load balancer, this method effectively addresses such imbalances. With sched_ext, we can collect training data and run inference on the model without modifying the kernel.

Our experiments demonstrate that, for certain workloads, this ML-driven approach can outperform EEVDF, offering notable performance gains for the CPU scheduler.
