Lightning Talk: A Reusable Zbus Based Architecture, Abstracting Core Application Components - Jaco Liebenberg, Plentify

Tuesday August 26, 2025 10:20 - 10:30 CEST

D202

Porting our products to Zephyr and a common microprocessor presented the opportunity to move to a higher proportion of common reusable code across devices. We present for community use and comment our architectural approach to developing a reusable Zephyr application code base.

We have leveraged zbus to create a standardised interface for inter thread communication, and a layer of zbus listeners (what we call a link layer) to enable our communication, UI, and system control to be reusable across products.

The approach is somewhat analogous to micro-services, in that our applications now each consist of ~5 independent services/modules. Each service delivers a specific independent function, and uses zbus to interface with the rest of the system in a common manner. But this is as far as the analogy goes. The choices were driven by a strong desire for maintaining a separation of concerns and modularity. So far it has proven itself to enhance testability, debugging, and to support significant code reuse and therefore maintainability of multiple code bases.

Bootloaders Under Fire: Real-World Threats and Practical Defenses - Ahmad Fatoum, Pengutronix

Tuesday August 26, 2025 11:00 - 11:40 CEST

Elicium 2

Bootloaders play a critical role in securing embedded systems, especially when implementing verified boot.

But while much attention goes into the cryptographic boot chain and run-time security, other parts of the bootloader are often overlooked — leaving a key component of the system exposed.

This talk outlines practical steps to harden a bootloader against different real-world threats.

Topics include identifying security-critical functionality, avoiding common pitfalls, slimming down the TCB and what kinds of hard- or software misconfiguration can silently undermine your defenses.

Along the way, we’ll use barebox as a practical example to show complementary approaches — like applying fuzzing to core logic, adding runtime hardening, and securely handling unlock scenarios — as well as how these could have mitigated a number of recently reported vulnerabilities.

Attendees will learn how to reduce risk during early system startup and improve the overall security posture of their embedded systems.

CoffeeCaller – a Fully Open Source Product Development Example - Andreas Kurz, TiaC Systems & Stefan Kraus, Independent

Tuesday August 26, 2025 11:00 - 11:40 CEST

D202

CoffeeCaller is an embedded device designed to coordinate coffee breaks between colleagues across an entire building. What began as a fun, free-time idea turned into an exploration of different product development approaches within the constraints of hobby time and budget. The goal wasn’t just to build something functional, but to try out techniques that could scale—from quick iterations to structured hardware-software integration.

We will show our journey from the idea to the finished project, that started with a simple proof of concept to validate the approach, followed by parallel development of hardware and software: While one created a custom hardware design in KiCad, the other development the actual application with Zephyr RTOS at the same time. We describe how we created the device tree as a bridge between both, keeping things modular and maintainable. We first implemented BLE Mesh for communication, later transitioning to openthread for broader connectivity. The entire project, including hardware and firmware, is open source.

Mirror and Control Android Phone With Zephyr on I.MX RT1170 - Phi Bang Nguyen & Trung Hieu Le, NXP Semiconductors

Tuesday August 26, 2025 11:00 - 11:40 CEST

D203

Mirroring and controlling a smartphone via a vehicle’s screen enable hands-free access while ensuring comfort and safety. Existing solutions like Android Auto or CarPlay require high-end MPUs and rich OSes. In this talk, we demonstrate a lightweight and low-cost alternative using the i.MX RT1170 MCU running Zephyr RTOS:

https://www.youtube.com/watch?v=EVt0pZxM8Xg

The Android phone captures its screen, compresses it in MJPEG, and streams it to the MCU. On the Zephyr side, we use ffmpeg for video decoding and send touch events to the phone. Despite no hardware decoder, we achieved 11 fps with 100–200 ms latency. MJPEG was chosen over H.264 for its better performance. Upcoming MCUs like the i.MX RT2660/RT2770 with MJPEG/H.264 hardware decoders will boost this further.

We are currently transitioning to Wi-Fi for a fully wireless set-up and offloading camera-based gesture control to the smartphone for hands-free controls. Finally, to inject touch events into Android without root access, the Android application needs to be launched in a shell by ADB from a laptop. We're working on porting ADB to Zephyr to automate this process for a seamless, plug-and-play user experience.

Cloud Native IoT: OTA Updates and Device Repurposing With K8s - Anastassios Nanos & Charalampos Mainas, Nubis PC

Tuesday August 26, 2025 11:55 - 12:35 CEST

Emerald Room

This session presents an open-source system for integrating resource-constrained IoT devices like ESP32-based MCUs into k8s-managed environments. It covers secure device onboarding using Entity Attestation Tokens (EATs) and OpenDICE, where devices generate cryptographic identities from hardware-embedded secrets and attest their state during registration and OTA updates.

Devices are discovered using Akri, which exposes them as addressable Kubernetes resources. Firmware is built and packaged as OCI artifacts, stored in standard registries, and deployed via a k8s "FlashJob" operator that lives alongside the Akri framework. Upon deployment, prior to joining the cluster, devices are onboarded and validated via Akri's discovery handler. When repurposed, devices are validated again, to ensure end-to-end attestation of both hardware and software components.

The session focuses on concrete mechanisms for OTA management, hardware-rooted identity, and distributed execution targeting constrained systems under k8s control.

Bridging Worlds: Using Device Tree Overlays To Support Complex PCI Devices in Linux - Hervé Codina, Bootlin

Tuesday August 26, 2025 11:55 - 12:35 CEST

Elicium 1

To support complex PCI devices, a new solution landed in Linux kernel (v6.13). It allows to describe hardware within a PCI device using a Device Tree (DT) overlay, taking advantages of the DT such as modularity, clarity, and wide driver support.

The Linux kernel provides a rich set of drivers for hardware blocks found in System-on-Chips (SoC). These drivers typically rely on DT descriptions. Some of those blocks appear in PCI devices. Instead of adapting drivers to the PCI context, why not having PCI devices working in a DT context?

The first driver using this feature is the driver for the Microchip LAN966x PCI device. The LAN966x SoC was already supported in the kernel, with Linux running on its ARM cores. Drivers exist for all its hardware blocks. The PCI device version is made from the SoC version where CPU cores have been replaced by a PCI endpoint. Using a DT overlay for PCI devices allows to reuse existing drivers without any modification.

This talk will delve into motivations and use cases behind this feature, followed by a dive into the implementation. We will present challenges encountered, how they were addressed, and what this means for future PCI device support.

From Backlog To Breakthrough: How FreeBSD and Bitergia Tackled 7k+ Bugs With Data-Driven Dashboards - Alice Sowerby, Rosmarin Ltd; Daniel Izquierdo Cortázar & Miguel Ángel Fernández Sánchez, Bitergia; Moin Rahman, The FreeBSD Project

Tuesday August 26, 2025 14:10 - 14:50 CEST

Auditorium

Every open source project has bugs—but what happens when you have more than 7k bug reports? The FreeBSD Project, a popular Unix-like OS that’s 30+ years old, faced a mounting backlog that risked overwhelming its contributors and users alike. Closing issues at random or based on age wasn’t an option. Instead, as part of work contracted by Germany’s Sovereign Tech Agency, the FreeBSD Foundation teamed up with Bitergia to build a smarter solution.

This panel discusses how the team used the OSS tool GrimoireLab to create customized dashboards to visualize FreeBSD’s Bugzilla backlog in new and actionable ways. You'll hear how metrics like the Backlog Management Index (BMI) and new bug categories like "unattended" and "abandoned" helped the team move from firefighting to focused bug triaging. We’ll also talk about technical challenges, like deploying GrimoireLab on FreeBSD itself, and the broader impact of contributing new features back to the CHAOSS open source community.

Whether you're drowning in bugs or just love data-driven engineering, this session shares practical tips, reusable metrics, and open source tools to improve bug management. Bring your questions—we’re excited to chat!

Identifying Safety Weaknesses and Fault Propagation in the Linux Kernel - Igor Stoppa, NVIDIA

Tuesday August 26, 2025 14:10 - 14:50 CEST

D204

Given the growing desire to use the Linux kernel in safety-relevant applications, like automotive, it is necessary to perform analysis and tests which are a staple of Functional Safety, but fairly new to Open Source Processes.

One of these is the injection of failures aimed at identifying data structures that might be particularly relevant from a safety perspective. This includes types of failures that would not lead to an immediate, clean crash, but rather to more subtle system degradation, that might be identifiable only when safety goals are compromised.

The methodology, and design presented constitute a tool that can be used to advance the understanding of what it entails to use Linux in safety applications. It could even be plugged into the regular upstream kernel post-release process, so that whenever a new Linux release is tagged, the tool will provide data related to how the new release behaves, when subject to controlled corruption.

Test Strategy for Zephyr - Maciej Perkowski, Nordic Semiconductor

Tuesday August 26, 2025 14:10 - 14:50 CEST

D203

In the dynamic world of software development, a well-defined test strategy is very important for ensuring quality and reliability. The Zephyr Project's testing activities have evolved organically to address immediate needs, however it lacked a formalized strategy. As the testing working group we developed a strategy that not only codifies existing practices but also covers new challenges, requiring a shift in our testing paradigm.

During the talk I will present the key elements of our strategy, like its objectives, main testing principles, roles and responsibilities, and other elements it is addressing. I will show how we plan to navigate the complexities of modern testing landscapes with a focus on effectiveness of the testing cycle without compromising the robustness and quality of the Zephyr Project.

Containers Live Migration: What’s There, What’s Missing, What’s Next? - Daniel Simionato, ControlPlane

Tuesday August 26, 2025 15:05 - 15:45 CEST

Emerald Room

Moving a running workload from one host to another transparently without disrupting its execution flow (“live migration”) is a solved problem for virtual machines, but still poses challenges for containers.

Current checkpoint and restore functionalities in both Kubernetes and LXD are somewhat limited or not completely fleshed out, and moving containers from one host to another involves either spinning up new replicas or stopping and restarting the containers, which is undesirable for stateful workloads like databases, machine learning or deep learning jobs.

Projects like CRIU (https://criu.org/Main_Page) and DMTCP (https://github.com/dmtcp/dmtcp) propose different approaches to offer checkpointing and restore functionalities in containers, but there is still no streamlined solution in LXD and Kubernetes.

In this lightning talk, we’ll go over the current state of the art, with a quick demo of what’s currently available, describing what’s missing and what will be the future developments to achieve seamless container live migration.

The Power of the Command Line - How Bash Can Boost Your Productivity - Werner Fischer, Thomas-Krenn.AG

Tuesday August 26, 2025 15:05 - 15:45 CEST

G109

Most Linux users use it every day: the bash shell. While Linux newbies only sporadically access the command line (terminal), their familiarity with it increases with continued use.

However, very few people take advantage of the sheer power of the bash. A basic understanding of the Bash grammar will help you get started: from simple commands, pipelines (|), lists, to compound commands, coprocesses, shell function definitions.

The Bash is incredibly versatile.

Quoting, for example, is used to remove the special meaning of certain characters or words to the shell. Values can be stored in parameters - of which there are several: positional parameters, special parameters, shell variables (e.g. $BASH, $LANG, $PATH, ...), arrays. Functions, arithmetic evaluation, conditional expressions and exit status are features often used in Bash scripts. Last but not least, shell bulletin commands are also part of the bash feature list.

Join Werner's talk and discover many possibilities for your favourite shell that you may have only dreamed of.

Navigating Compliance: What Developers Can Learn From Driving - Kadi McKean & Charlie Jones, ReversingLabs

Tuesday August 26, 2025 15:05 - 15:45 CEST

G105

When driving on a highway, you have to follow the rules of the road—some apply to everyone, while others only apply to commercial drivers. Open source maintainers and software publishers face a similar divide regarding regulatory compliance.

While software manufacturers must meet extensive legal and security obligations, open source maintainers often assume these regulations do not apply directly to them—but do they? In this talk, we’ll separate fact from fiction by breaking down what rules like the EU Cyber Resilience Act require from maintainers versus software vendors.

We’ll explore the limited enforceable obligations for open source projects, including secure development policies and vulnerability reporting, and discuss when (if ever) these rules impact maintainers. By understanding these distinctions, open source contributors can make informed decisions about risk, responsibility, and collaboration with commercial software teams—without unnecessary compliance burdens.

Lightning Talk: Reliable Recovery in Partitioned Embedded Systems Using IVSHMEM and Jailhouse Hypervisor - Paresh Bhagat, Texas Instruments

Tuesday August 26, 2025 16:20 - 16:30 CEST

Elicium 1

In industrial and real-time embedded environments, system uptime and fault recovery are mission critical. This proposal explores a lightweight and effective technique for crash detection and recovery using Inter-VM Shared Memory (IVSHMEM) within the Jailhouse hypervisor. By continuously sharing heartbeat or health status between the root cell and inmate (guest OS) via shared memory, the system can quickly detect unresponsive partitions and trigger recovery mechanisms like automated restarts without a full system reboot. We demonstrate this approach on TI SITARA EVMs, showing how it minimizes downtime without a full system reboot. Through this talk, I aim to share a reusable pattern for enhancing system reliability and show how open-source virtualization can be leveraged for resilient industrial applications. Attendees will gain insights into partitioned system design, shared memory communication, and recovery strategies for embedded systems. I hope to receive feedback on enhancing this approach and hear from others solving similar reliability challenges in embedded systems.

This talk presents our approach to integrating OpenStack cloud infrastructure with NixOS, addressing a significant gap in development workflows for OpenStack Nova.

Our primary motivation was to simplify testing and development processes by leveraging NixOS' declarative and reproducible environment capabilities. We'll demonstrate how our implementation uses NixOS modules to create deterministic OpenStack deployments where components - particularly the Nova compute and the Neutron network service - are defined as NixOS modules within the Nix expression language. This approach eliminates configuration drift during development cycles and enables developers to quickly reproduce specific environments.

We'll share practical insights from our implementation journey, highlighting how this integration streamlines OpenStack development workflows through consistent test environments and easy service configuration manipulation. We'll discuss the qualitative improvements in developer experience and outline future directions for expanding NixOS support across the OpenStack ecosystem.

In this talk we will discuss why people use multi-tenency to run containers from multiple users in the same cluster, the risks of multi-tenency, and what we can do about these risks. We will survey technologies with different levels of container isolation, from relying on namespaces to using virtual machines to using separate hardware. Each level of isolation is right for some use cases, so we will discuss the pros and cons of each.

Data Placement in Linux: Evolving Block and File I/O - Kanchan Joshi, Samsung Semiconductor

Tuesday August 26, 2025 16:20 - 17:00 CEST

G104

As technologies evolve, so must Linux. Flexible Data Placement (FDP) is a new storage capability that gives the host more influence over the physical data layout—crucial for improving performance, usable space, and overall energy efficiency.

While initial Linux support was possible through an io_uring-driven passthrough interface, many real-world deployments require block and file path support, as well as collaboration across the I/O stack.

This talk will present the current state in Linux, dive into key design decisions, and walk through how both block and file I/O paths are being adapted to better take advantage of data placement. Expect discussion around the use of per-file and extended per-I/O interfaces that involve io_uring, filesystems, the block layer, and the NVMe driver.

Travel Retail Disruption Using Open Source - Stu Waldron, Open Travel Alliance

Tuesday August 26, 2025 16:20 - 17:00 CEST

Auditorium

Travel retail, shopping and booking stays, activities, or trips, is ripe for disruption using open source. Fifty years on from its inception, the process of shopping and purchasing travel products has been computerized and exposed online but works largely the same as it always did. Even as some legacy components have been replaced, their limitations are still present embodied in workflows and policy. Stateful, transactional, processing is still the order of the day. It all needs to be overhauled to move into a stateless, cloud based, digital world. Travel retail is unaffordable in its current form, open source is the obvious answer. As a community, make one investment to create the needed foundational capabilities such as offer/order management, security, identity management, event management, rules processing and much more. Noncompetitive functions everyone needs to create traveler solutions such as end to end trip solions and management via an AI powered app. The Open Travel Alliance is working with the Linux Foundation to form the Open Travel Foundation. This session will explain how this new foundation will transform travel retail.

Who maintains the software components everyone uses? Without open source libraries, protocols & tools, the world would grind to a halt. When it comes to sewers, roads & bridges, the government pays. For bits & bytes? There's a German phrase: digitale Daseinsvorsorge.

Who builds and maintains the sewers under our feet? The government! The same goes for the trains we ride and the roads we walk on. When we ask these questions about the basic components that underpin our world's digital infrastructure, the answer is very different. It's Daniel for curl, Piotr, Christian & Volkan for Log4j, a small team for Fortran, Sarah for Nominatim, Richard at Yocto and countless other maintainers.

At a time when software is eating the world, these foundations are terrifyingly precarious. We hope we're paying the right people to do the critical work of maintaining/securing these systems.

Historically, this results in hardware targets embedding chips that are qualified and tolerant to the environment (radiation in particular), but rather old, expensive and produced in small batches.

The expansion of “New Space” has democratized the use of COTS, considerably increasing available onboard computing power and opening up new ways of embedding applications in satellites.

While it can be tedious to port an application onboard (limited to C language, restricted memory and computing power, limited user community...), using Linux minimizes the effort involved in porting an algorithm onboard. However, the world of on-board space applications requires compliance with numerous rules and standards. This presentation aims to provide an overview of the challenges involved in using Linux onboard a space system.

The aim is to give an overview of how we make embedded software at CNES and how Linux can take us to new dimensions. The following topics will be discussed regarding embedded Linux for space applications :

- Real time aspects

- Reliability

- Processes segregation
