Greg KH
Linux FoundationThe CRA and what it means for us.
Greg Kroah-Hartman is a Fellow at the Linux Foundation. He is responsible for the stable Linux kernel releases, and is also the maintainer of the USB, driver core, staging drivers, and other portions of the Linux kernel. He spends his time reviewing patches and traveling to conferences to give presentations.
With the ratification of the Cyber Resilience Act (CRA) in Europe, there has been a lot of misunderstanding of what this means for Linux developers, Linux users, and manufacturers of devices with Linux inside of them. This talk will attempt to provide a rough understanding of the issues involved, who is affected, and what this means for everyone in our ecosystem.
Marta Rybczynska
YgrekyElephants in our embedded security room
Marta Rybczynska has PhD in network security, and 20 years of experience in Open Source including 15 in embedded development. She has been working with embedded operating systems like Linux and various real-time ones, system libraries and frameworks up to user interfaces. Her specialties are architecture-specific parts of the Linux kernel. In the last years, she focuses on improving security of Open Source products. She is helping the Eclipse Foundation with security processes for their 400+ open source projects, and also a member of the Security Team of the Yocto Project. In 2024, she founded Ygreky, a company dedicated to making open-source security stronger and more practical. Ygreky equips developers, architects, and tech leaders with top-tier training, expert guidance, and powerful tools to build safer, more resilient embedded software.
Security researchers often assume that embedded developers don’t care about security. But from what Marta hears from her customers - ranging from startups and freelancers to established companies - that’s simply not true. Developers want to build secure products, and managers are increasingly aware of regulations like the Cyber Resilience Act. So why is embedded security still lagging? This talk uncovers the structural barriers holding us back: legacy systems, the late arrival of networking, missing architectural decisions, relentless cost pressures, and more. For each challenge, you’ll walk away with a concrete action to improve security - starting the moment you return from the conference. And no, the Linux kernel CVEs aren’t the real problem.

John Ogness
LinutronixWriting Linux Real-Time Applications
John Ogness studied Computer Science at Utah State University (USA) and has been professionally involved with Linux since 2001. He has been working for the company Linutronix GmbH since 2008. There he specializes in Linux-based board support packages, real-time applications, and training. He is also maintainer of the Minicoredumper project. In the past, he developed software for security applications and autonomous robots.
Real-Time support for Linux has been available for nearly two decades and is even part of the mainline kernel since Linux 6.12. But how do you write real-time applications for Linux? This talk provides an overview of the fundamental concepts of PREEMPT_RT (from a userland perspective) as well as insight into designing and implementing real-time applications. A new upcoming Runtime Verifier (RV) monitor for real-time applications is introduced that can identify patterns of incorrect behavior. This new RV monitor was recently used to detect issues within PipeWire's implementation. Those issues and their solutions will be shown, illustrating the importance of understanding PREEMPT_RT.
Oleksij Rempel
PengutronixPersistent Shutdown Reasons & Hardware Protection: Making Embedded Systems More Resilient
Oleksij Rempel is an embedded Linux developer and part of the kernel hacker team at Pengutronix. With experience in automotive infotainment systems and now working primarily with agricultural and industrial devices, he focuses on diagnostics, networking, and system reliability in embedded environments. Even though he is not directly involved in hardware development, his passion lies in understanding system behavior, debugging complex failures, and ensuring reliable communication between embedded devices.
Embedded systems frequently experience hardware protection events such as undervoltage, overcurrent, and thermal shutdowns, leading to unexpected resets, data corruption, and even hardware failure. However, in many cases, the system does not persistently record the cause of a shutdown or resets, making it difficult to analyze and diagnose failures in the field. Traditional logging to NAND or eMMC is often unreliable in power-critical scenarios due to the risk of sudden power loss, storage wear-out, or corruption. To address this, the Power State Change Reasons Recording (PSCRR) framework enables embedded systems to persist shutdown reasons in alternative non-volatile storage, such as EEPROM, RTC scratchpads, or NVMEM-backed solutions. This talk presents the current state of PSCRR, the challenges encountered, and ongoing efforts to improve power-fault diagnostics in embedded Linux.
Marek Vasut
ConsultantSafe update of firmware blobs in bootloader stack
Marek is an embedded systems consultant, with primary focus on upstream U-Boot bootloader, Linux kernel and OpenEmbedded. Recently, Marek has been working on hardware assisted testing instrumentation for various embedded system components to improve long term maintainability.
Contemporary bootloader stacks are increasingly interleaved by assorted firmware blobs. These blobs often run in the highest privilege levels available in the system. Some of these blobs provide firmware ABI used by follow up software layers, like the U-Boot bootloader or the Linux kernel. Such an ABI exposes an attack surface and therefore turns the blobs into security sensitive software components which have to be safely updateable. However, the firmware ABI in various downstream vendor BSPs is not necessarily stable and not necessarily compatible with mainline expectations of the matching ABIs, which makes updates difficult, dangerous, or otherwise complicated. With the upcoming CRA, ability to update all security-sensitive components will be a strong requirement. This talk covers three key topics. Replacement of external bootloader stages by U-Boot, which provides the necessary facilities to boot and update firmware blobs in a well defined manner. Details of the mechanism used for booting firmware blobs like TFA or OpTee-OS, which provide PSCI and SCMI interfaces, from U-Boot as part of a fitImage container. U-Boot boot time optimization and attack surface reduction by starting both the firmware blobs and Linux kernel directly from U-Boot SPL using Falcon Boot mode.

Igalia⚡ Yocto's hidden gem: OTA and seamless updates with systemd-sysupdate
Martín is a Software Engineer from Paraguay, Open Source contributor for the GNOME project and part of the Core team at Igalia.
Updates are a critical piece of managing your fleet of devices. Nowadays, Yocto-based distributions can utilize layers for well-established update mechanisms [1]. But, did you know that recent releases of Yocto already come with a simple update mechanism? Enter systemd-sysupdate: a mechanism capable of automatically discovering, downloading, and installing A/B-style updates [2]. By combining it with tools like systemd-boot, we can turn it into a comprehensive alternative for common scenarios. In this lightning talk, we will briefly introduce systemd-sysupdate, show how it can be integrated with your Yocto distribution, and share thoughts on how it can be improved further.

Wolfram Sang
Renesas⚡ I3C - the better I2C?
Wolfram became a Linux Kernel developer in 2008. He currently maintains the I2C subsystem and works as a consultant and mentor, mainly for the Renesas Upstream Kernel Team. Programming since his childhood, he still hacks his machines from the 80s, especially the C64. When not using computers, he is interested in ecological topics, enjoys cooking and tries to keep his Japanese alive. He likes to give talks and has done so at various conferences all around the world, mostly about kernel topics.
Announced in 2014 and first specification released in 2017, I3C has been around for a while. The self-proclaimed successor of I2C wants to overcome old limitations whilst adding new features on top. However, most embedded Linux engineers have not been in contact with this technology so far, although there is support for it in the Kernel since 2017. This is also true for the author of this talk who was given the task to upstream an I3C controller driver for a Renesas SoC in late 2024. Despite his experience with I2C (being the maintainer of that subsystem), I3C was quite a different world to enter. Where to get information? Where to find devices? How to test? Why is it hardly known? This talk is basically my travel report. I will present my discoveries, share my experiences, and tell you about my observations about the current state-of-affairs. So, I3C will be a better known and understood territory for fellow travellers afterwards.
