Navigating Security Tradeoffs in Embedded Linux Systems - Olivier Benjamin, Bootlin

Monday August 25, 2025 09:00 - 09:40 CEST

Elicium 2

Embedded systems vary wildly in purpose, characteristics and usage. They are therefore faced with very different adversaries, that engineers and designers must take into account to achieve a secure system or product.
The tradeoff between security and convenience can only be properly arbitrated by evaluating the benefits of each security measure against the cost of its implementation, and the added complexity to the system, which will eventually be surfaced to the user.

In this talk, we will explore the security guarantees of various
security measures popular in embedded Linux systems: Secure Boot, Disk encryption, dm-verity, Secure Enclaves as well as someapplication-level security features from the point of view of what they bring to a system, and what they cost to the implementer or theuser. Ultimately, we will present what type of systems they are a good fit for, and which systems are probably better off not using them.

Open Source for ESIM Integration - Harald Welte, sysmocom GmbH

Monday August 25, 2025 09:00 - 09:40 CEST

D201

When integrating eSIMs into a Linux based embedded device, one of the questions is how to manage that eSIM. In case of SGP.21 consumer eSIM or the new SGP.31 IoT eSIM, some software component for management and download of eSIM profiles (LPA or IPA) is required. In the past, this was mostly achieved by proprietary software.

More recently, Free and Open Source Software alternatives for this have materialized, like the "lpac" software. This talk covers those projects, what you can do with them and how to integrate them in your cellular-enabled embedded device.

The talk will also compare this approach of eSIM integration with other approaches such as the venerable SGP.02 M2M eSIM or using an eUICC-integrated LPA/IPA (LPAe/IPAe).

Why Won't My CPU Sleep? Debugging CPUIdle Mysteries on ARM SoCs - Dhruva Gole, Texas Instruments India Ltd & Kevin Hilman, BayLibre, Inc.

Monday August 25, 2025 09:00 - 09:40 CEST

Elicium 1

Linux power management has relied on CPUIdle to transition CPUs into low-power states for a long time. More recently, suspend-to-idle (s2idle) was added which relies heavily on the CPUidle infrastructure to support system-wide suspend & resume using low-power idle states.

On modern Arm SoCs, deeper idle states can shut down not just the CPU, but also local per-CPU timers, interrupt controllers and peripherals, sometimes leading to unexpected entry-exit failures, scheduling delays, and even system hangs.
Debugging such issues can be complex since common debug methods may not be available in low-power modes and because the kernel, platform-specific firmware and dedicated hardware all interact to enable low-power modes. Therefore, debugging requires a good understanding of the CPUIdle internals, PSCI firmware interactions and wakeup timer behavior.

Through real-world case studies, attendees will learn how to trace idle state transitions, identify CPU wakeup failures, ARM Trusted Firmware's PSCI framework internals and apply effective debugging strategies to ensure correct working of the CPUIdle framework on their ARM Linux systems.

The Hypervisor Hierarchy: Why Architecture Matters for Performance, Security, and Flexibility - Cody Zuschlag, Xen Project (Linux Foundation)

Monday August 25, 2025 11:20 - 12:00 CEST

G001-002

Not all hypervisors are created equal. Some claim to be "bare metal" but rely on an underlying OS, while others truly separate hardware from workloads, enhancing security, stability, and performance. This session breaks down the differences between Type 1 and Type 2 hypervisors, why some architectures blur the lines, and how Xen stands apart as a true, independent Type 1 hypervisor. We’ll explore how Xen can run with dom0 or dom0less, offering flexibility for both dynamic and fixed VM environments. We’ll also discuss how Xen’s streamlined, unified ecosystem avoids the fragmentation seen in other virtualization stacks. Attendees will leave with a clear understanding of why hypervisor design matters and how it impacts security, efficiency, and long-term infrastructure choices.

Clocking Strategies in the Linux Kernel: Optimizing Power and Performance in High-End SoCs - Varada Pavani & Bala Naveena Nivetha M, Samsung Semiconductor India Research

Monday August 25, 2025 11:20 - 12:00 CEST

Elicium 1

Modern System-on-Chips (SoCs) are designed for a wide range of applications, including mobile devices, automotive systems, AI accelerators, and data servers. As SoCs become more powerful with increasing core counts, heterogeneous architectures, higher clock speeds, and enhanced AI processing capabilities, power consumption also rises. This increased power demand introduces challenges such as heat dissipation, battery life, clock management complexity and system reliability. In this talk, we explore various techniques to optimize power consumption and enhance performance using Common Clock Framework (CCF) in the Linux kernel.

We begin by discussing the role of clock management in Linux and covers various clocking strategies available in CCF to achieve optimal power and performance. Topics include dynamic clock scaling, disabling unused clocks, efficient parent clock selection and the notifier mechanism. We also explore clock usage monitoring in Linux through debugging tools such as clk_summary and kernel tracing.

Overall, this talk demonstrates how effective clocking strategies in the Linux kernel can significantly improve power efficiency and system performance in high-end SoCs.

Combining White-labelled Hardware With Open Source Software To Quickly Bring Devices To Market - Nick Chen, Blecon Ltd

Monday August 25, 2025 11:20 - 12:00 CEST

Elicium 2

The ODM ecosystem — such as the one found in Asia — offers a rich selection of pre-designed hardware intended for white-labelling. This hardware can be produced and shipped with short lead times. However, a typical weakness of these devices is their software, which usually consists of outdated kernels and poorly documented components. Wholesale replacement of the system’s software stack while leveraging the hardware offers a path toward creating robust devices that can sidestep many of the complexities of manufacturing a fully custom design.

In this session we share tips and learnings from our experience creating a replacement software stack using Yocto for an existing white-label IoT gateway device. With this approach, we were able to take a new device with an up-to-date Linux stack to production in under 6 months.

The session will cover topics including: choosing of an appropriate hardware platform, coordinating with the hardware vendor, setting up an efficient development environment using similar hardware and simulators, and using the system’s OTA update infrastructure to create a factory image that’s compatible with an ODM’s existing manufacturing and testing flows.

Rethinking Writeback: Scaling Linux Filesystem and Memory Performance for the Next Decade - Kundan Kumar, Samsung R&D Institute India - Bangalore & Anuj Gupta, Samsung Semiconductor India

Monday August 25, 2025 11:20 - 12:00 CEST

G104

Linux’s current writeback infrastructure, while robust, was designed before large folios, CXL-tiered memory, and AI workloads demanding low-latency, high-throughput I/O. Today, workloads like RAG pipelines using vector databases with buffered I/O, and memory tiering on CXL, are exposing scalability limits in how the kernel handles writeback.

This talk presents a forward-looking view on evolving Linux’s writeback model. We’ll explore how the single-threaded design stalls page migration and reduces memory compaction effectiveness—affecting hugepage allocations and folio movement across memory tiers, contributing to fragmentation. On the storage side, parallelizing writeback improves throughput and responsiveness under dirty-page pressure, especially for sustained-write workloads with large memory footprints on High capacity SSDs.

We’ll also touch on early experiments within the kernel community, including efforts to make writeback more filesystem-geometry aware and parallelize it based on overwrites/new allocations.

This session invites open source community to reimagine writeback as a scalable, performance-critical component in Linux.

When we talk about cloud security, the first thing that comes to mind is otters. Obviously.

In this talk, we’ll dive into the fascinating analogy between the world of cloud security and wildlife. We’ll explore Falco, eBPF, and others and how they relate to our very own animal ecosystem. This perspective offers a unique and intuitive way to understand cloud security.

Think of chameleons and adaptive security: changing colours to match evolving threats.

We’ll migrate like birds, discovering security’s role in real-world workload transitions across clouds.

We’ll collaborate like bees, protecting the hive with policies, alerts, and shared responsibility.

We’ll defend like armadillos, layer by layer, showing how strong defence is often the best offence.

And we’ll feel our spider-sense tingle — like observability tools catching anomalies across the great web of services.

And, just like otters, we’ll hold hands to stay together in the rushing currents of the cloud.

And who’s heard of chaos monkeys? Clever and unpredictable, just like attackers exploiting misconfigurations and edge cases! We’ll take a look at how that plays out in the wild world of cloud-native security.

Designing Policy and Support for a Sustainable Open Source Adoption in the Public Sector - Johan Linåker & Sachiko Muto, RISE Research Institutes of Sweden

Monday August 25, 2025 13:30 - 14:10 CEST

G105

The public sector has been an active user of Open Source Software (OSS) since its inception. Yet, adoption and reuse have fluctuated, along with the many policies and initiatives providing guidance and support. On the positive side, there is a wealth of experience to draw from.

In this presentation, we aim to inspire and provide insights from a study of 16 countries that are mature in their digital practices, as indicated through a set of digital maturity indicators. These countries are surveyed regarding government policies, rationales, support mechanisms, means of promotion, and success stories on OSS adoption.

We find diverse means in how policy is designed and motivated to support both the adoption and use, as well as development and release of OSS across sectors. The cases further provide in-depth examples of how the policies can be supported and enabled using Open Source Program Offices (OSPOs), communities, and codified knowledge.

Based on our findings, we will provide attendees as well as policy- and decisionmakers at national, regional, and local government levels, with recommendations for designing and fostering sustainable policies for OSS adoption.

Extending BCC as a Data Source for System Monitoring - Eunseon Lee, LG Electronics

Monday August 25, 2025 14:25 - 15:05 CEST

G104

eBPF enables efficient tracing and monitoring of modern Linux systems. However, tools in the BCC (BPF Compiler Collection) are primarily designed for standalone use, making it challenging to adopt them directly in real-time, streaming-based observability systems.

This talk introduces a practical approach to extending BCC tools for use as data sources in system monitoring pipelines. I demonstrate an architecture that transforms BCC output into time-series data by integrating with InfluxDB, and visualizes the data using Grafana. This enables real-time tracking of kernel and user-space events such as memory allocation over time.

I also explore enhancements to existing BCC tools, such as adding options to output data in time-series–friendly formats (e.g., InfluxDB’s line protocol), enabling easier ingestion by monitoring agents. These modifications help bridge the gap between raw eBPF observability and modern telemetry systems, without compromising BCC’s standalone usability. GitHub PR (https://github.com/iovisor/bcc/pull/5281) demonstrate these improvements.

Attendees will learn to leverage BCC tools for real-time insights and contribute enhancements for broader monitoring use cases.

Driving the UN Digital Compact With Open Source - Sachiko Muto, RISE/OpenForum Europe

Monday August 25, 2025 14:25 - 15:05 CEST

Auditorium

Open Source Software (OSS) is increasingly recognized as a crucial enabler of the Sustainable Development Goals (SDGs) and digital transformation across the globe. Yet, adoption and contribution remain uneven, with certain regions and actors underrepresented, especially in the global south.

With initiatives such as the UN’s Digital Global Compact and Open Source Principles, there is growing momentum and an opportunity to better understand and measure OSS’s role in digital infrastructure and government strategies. As part of this effort, we are exploring the development of an Open Source Adoption Index, published annually to track adoption trends, highlight successes, and identify challenges faced by UN Member States.

The adoption index will be collaboratively designed through a series of geographically distributed workshops to collect dimensions relevant across various contexts and use cases. In this panel, attendees will be actively engaged, as part of this extensive co-design process, and be urged to provide thoughts and feedback to the panel of representatives from the UN, researchers and stakeholders.

Security in Large Scale Embedded Linux Projects - Martin Lang, BMW Car IT GmbH

Monday August 25, 2025 15:35 - 16:15 CEST

Elicium 2

Modern cars use a high integration architecture with a smaller amount of powerful Electronic Control Units (ECUs). They easily accommodate more than 150 different services and are developed by more than 1000 developers in dozens of companies across the world. Ensuring security in such an environment is a challenge in multiple dimensions: Attack surface, overall system complexity and communication.

In this talk, I want to share our insights from building three generations of Yocto-based infotainment systems. How do we ensure basics such as the least privilege principle and privilege separation? What is our approach to trusted computing with secure boot and dm-verity? What are our lessons learned to enable SELinux on this large scale? Which best-practices do we have so that the system can be developed, tested and debugged in a (security) configuration that is close to the final product?

Furthermore, I would like to give positive examples how a good open-source ecosystem can support our cause of building secure embedded Linux systems as well as some impulses which improvements could help us a lot.

As organizations race to integrate AI into their infrastructure, products, and processes, they face a shared set of challenges, ranging from data fragmentation, ethical governance, to cost management and sustainability. What’s often overlooked in these conversations is the essential role of open source: the AI technology stack today is built upon thousands of open source projects and frameworks, as well as some not-so open source offerings. Yet, many organizations still lack a coordinated strategy for engaging with and contributing to this foundational ecosystem.

This BoF session aims to provide a collaborative space for OSPO teams, platform architects, AI engineers, compliance professionals, etc to come together and explore how open source management talent helps organizations navigate AI adoption, and creation, sustainably and effectively. An open floor to exchange experiences and identify issues such as:

- Interface with legal and compliance teams

- New standards related to AI models and infrastructure, such as model cards, etc

- Balancing OSS transparency with Responsible AI development

- Do AI communities differ from traditional OSS communities, and how to approach them

Monday August 25, 2025 15:35 - 16:15 CEST

G106

To securely deploy an identity and access management product implementing authentication & authorisation specifications like OpenID Connect 1.0 and OAuth 2.0 respectively, we need to ensure that the specifications are safe, the product correctly implements the specifications, and the product does not contain any vulnerabilities specific to the specifications. Methods for checking these points are formal analysis, conformance testing, and vulnerability testing, respectively. However, developers are not usually familiar with them. Based on the speaker’s investigation on academic research, the speaker describes them in a straightforward way.

The speaker is a maintainer of Keycloak, identity and access management open source software, CNCF incubating project. Therefore, the speaker will use Keycloak as a case study and explain how the specifications that Keycloak implements are verified to be secure and how Keycloak is verified to be compliant with the specifications.

Video4Zephyr: From Basic APIs Towards a Full-fledged Video Subsystem - Phi Bang Nguyen, NXP Semiconductors

Monday August 25, 2025 16:30 - 17:10 CEST

D203

Originally introduced in 2019, the Video4Zephyr (v4z) APIs provided a foundational interface for interacting with video devices in Zephyr. However, with minimal changes over the years, their limitations have become apparent—especially as video hardware grows more complex and camera-based applications become increasingly demanding.

This talk presents the current status of v4z, hightlighting recent improvements as well as sharing ongoing and upcomming works which turns the v4z from a simple driver API into a robust video subsystem. We’ll cover the devicetree video port/endpoint mechanism, a unified video control framework, enhanced buffer management, and support for memory-to-memory (m2m) devices, etc. These efforts aim to shift commont functionality and logic into the subsystem itself, significantly reduce the burden on driver developers - bringing the Zephyr’s video stack closer to a mature multimedia framework.
