Exploring the Power of eBPF for System Observability - Shaghayegh Tavakoli, IONOS & Zahra Dehghanpour, bol.

Wednesday August 27, 2025 14:10 - 14:50 CEST

G102-103

This talk offers a gentle and practical introduction to eBPF as a powerful framework for Linux and network observability. We’ll walk through real scenarios—like tracing incoming packets, measuring syscall latency, and visualizing kernel behavior using tools like bpftrace and bcc.

While often seen as advanced, eBPF is surprisingly accessible. You don’t need deep kernel knowledge or C programming skills to start using it. Whether you're a developer, sysadmin, or just curious about how Linux works under the hood, this talk shows how eBPF can make observability approachable and even fun.

We'll focus on how eBPF helps answer complex performance and debugging questions in a modern, efficient, and safe way—turning opaque system behavior into actionable insights using just the command line and some well-crafted trace scripts.

Strategies for Rate Limiting Network Packet Ingress - Schuyler Patton & Daolin Qiu, Texas Instruments

Wednesday August 27, 2025 15:05 - 15:45 CEST

G102-103

A major concern of a network connected application on an embedded platform is reducing any impact from high network traffic that is unrelated to the running application. Typically, this is called network broadcast storms and network attacks. Rate limiting packet ingress is a key strategy in preventing high processor bandwidth consumption caused by a network storm. In general, rate limiting packet ingress implies intentionally dropping packets. In order to setup ingress rate limiting, several different options are possible. These options include evaluating the tc Linux utility (e.g. tc qdisc), eBPF, or simply adjusting the Ethernet PHY link speed. A demonstration of these three options in action and how they can be used to prevent high-rate ingress traffic from causing negative processor impact will be showcased. A comparison of the impact from using tc and eBPF will also be discussed. The overall goal is to use these options to drop ingress packets in order to minimize ARM microprocessor bandwidth.

Civil Infrastructure Platform: State of Industrial Grade Linux - Yoshitake Kobayashi & Dinesh Kumar, Toshiba Corporation

Wednesday August 27, 2025 16:20 - 17:00 CEST

G102-103

The Civil Infrastructure Platform (CIP) project continues to advance Industrial Grade Linux for mission-critical systems requiring long-term reliability, security, and regulatory alignment. This talk will provide the latest updates across CIP’s core activities. We’ll begin with progress on the next Super Long-Term Support (SLTS) CIP kernel based on Linux 6.12, designed to offer a robust foundation for products with extended life cycles.

Then, we’ll cover CIP Security Working Group activities, including alignment with IEC 62443-4. Following successful 4-1 process conformance in 2024, efforts now focus on meeting the technical requirements of 4-2. These activities not only support industry best practices but also lay groundwork for compliance with the EU Cyber Resilience Act (CRA). We will also share updates from the Software Update Working Group, which is integrating The Update Framework (TUF) to ensure secure and reliable updates for embedded systems. Finally, we will highlight contribution trends and point to resources for developers and companies looking to engage with CIP and help shape secure, sustainable Linux-based critical infrastructure.
