FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels.
The ELISA Project Ambassadors will be at FOSDEM 2026, actively participating across the event. They will be giving presentations, joining discussions, and meeting contributors and attendees in various developer rooms throughout the weekend. You can also connect with them at the Linux Foundation Europe stand, where they will be available to talk about ongoing work, community activities, and how to get involved with ELISA.
In addition, Philipp Ahmann, ELISA TSC Chair, Systems and Automotive WG Chair, and Sr. OSS Community Manager at ETAS GmbH (BOSCH), will be giving a talk at FOSDEM 2026. Philipp will also be at the Linux Foundation Europe stand throughout the weekend for anyone who would like to learn more about the ELISA Project, ask technical questions, or discuss collaboration opportunities.
From the TSC, Kate Stewart (VP, Dependable Embedded Systems, The Linux Foundation) and Nicole Pappler (Senior Safety Expert & Founder at AlektoMetis.com) will also be at FOSDEM.
Session Highlight:
Code, Compliance, and Confusion: Open Source in Safety-Critical Products
The integration of Open Source Software (OSS) in functionally safe systems represents a critical intersection of innovation and compliance requirements across multiple industries. This talk examines two complementary aspects of this evolving landscape: the current state of OSS in functional safety applications and the persistent barriers hindering wider adoption.
2024/2025 have marked significant acceleration in the visibility and adoption of OSS in safety-critical environments, with diverse projects demonstrating varying levels of maturity. Foundation-backed initiatives like the ELISA project within the Linux Foundation are establishing frameworks for Linux in safety applications, while specialized operating systems such as Zephyr and Xen continue to gain traction. The Eclipse Foundation’s Safe Open Vehicle Core (S-Core) project represents another significant advancement, aiming to create a common certifiable automotive middleware stack that addresses critical safety requirements. The ecosystem now spans from microkernel solutions like L4Re and seL4 to full-featured platforms, with Linux serving as a prime example of the opportunities and challenges in this space. Infrastructure improvements like the SPDX safety profile address critical aspects of safety documentation in Software Bill of Materials (SBOMs), while safety-certified components like the Ferrocene Rust compiler create new possibilities for language-level safety guarantees.
Despite this progress, substantial barriers impede broader OSS adoption in functionally safe systems. A particularly persistent challenge remains the confusion around terminology and approaches – exemplified by the distinctions between “safety Linux” versus “safe Linux” that illustrate broader issues in how safety responsibility is allocated between OSS components and system-level mitigations. By examining architectural concepts currently implemented in production systems or under development, this talk cuts through marketing rhetoric to provide clear distinctions between approaches across various open source technologies.
The author will address uncertainty around certification pathways, challenges in establishing sufficient evidence for safety arguments, fragmented governance models, and incomplete understanding of OSS development processes among safety assessors.
Attendees will gain practical insights for evaluating safety approaches in OSS-based systems, including key questions to ask when assessing different safety concepts across industries, with particular emphasis on applications where both manufacturers and suppliers are seeking to implement open source software in safety-critical production systems.
