SBOM Implementation Reality - from Crawl to Walk, the SPDX Lite Profile for the First Step - Norio Kobota, Sony Group Corporation & Takashi Ninjouji, Toshiba Corporation

Monday September 16, 2024 11:20 - 12:00 CEST

Room 0.49-0.50 (Level 0)

This session will introduce the SPDX Lite profile, its background, and what and how it solves with many JSON examples. The Lite profile of SPDX 3.0 is designed to make it quick and easy to start creating a Software Bill of Materials (SBOMs) when a company has limited capacity for introducing new items into its process. Over the past few years, the importance of SBOM has increased. As interest in SBOM from government agencies and industries grows, the SBOM specification extends significantly to meet these various needs. SPDX Lite is a lightweight and compact SBOM specification. The OpenChain Project Japan WG explores and promotes SBOM. The focus is on making the SBOM practical from security assurance and license compliance perspectives and on sharing and transferring SBOM across the global software supply chain in any industry. SPDX Lite is one of the achievements of collaboration between the OpenChain project and the SPDX project. Attendees in this session will learn the first steps to creating an SBOM using the Lite profile of SPDX 3.0 by several examples of SBOM documents that address regulations and requirements.

Open Source and IP Departments: Risk Containment and Portfolio Management - Shane Coughlan, The Linux Foundation

Monday September 16, 2024 12:15 - 12:35 CEST

Room 0.49-0.50 (Level 0)

Product teams, R&D teams and OSPOs occasionally find themselves in an adversarial situation with IP Departments around open source and how it should be managed in an organization. This is usually due to misunderstandings about how open source provides value and how the risks associated with it can be contained. With open source increasingly necessary for organizations to compete effectively, it is important to ensure all departments understand its strategic importance, and how to manage it in the context of their KPIs and requirements. This talk will explain how to collaborate with IP Departments using the language of external risk containment and internal portfolio management, and help IP Department staff assess open source as part of a diversified IPR strategy.

Virter – How the "Docker for VMs" Can Help You Test the Linux Kernel - Christoph Böhmwalder, LINBIT HA-Solutions GmbH

Monday September 16, 2024 12:15 - 12:55 CEST

Hall M2 (Level 1)

Testing the Linux kernel and its associated components at scale presents unique challenges compared to other software projects. While user-space projects can usually use containers to efficiently and quickly run their integration tests, kernel-level software requires virtual machines, making the process more difficult. At LINBIT, we also notice this when developing our Linux kernel driver, DRBD, and other components that depend on it.

That is why, after several iterations with other approaches, we have created our own open-source tool for the task: Virter, a "Docker for VMs."
Virter isn't just a proof-of-concept; it's a practical solution. Its primary design goal is to simplify the provisioning, cloning, and running of virtual machines. We currently use it to run around 40,000 VM instances every day as part of our testing efforts.

In this talk, we will share our experience testing the Linux kernel, a journey that ultimately led to the creation of Virter. We will demonstrate how we now use Virter to effectively and efficiently test Linux kernel components and explore how your workflow might benefit from it, too.

Enhancing Kernel Functional Safety Analysis with KS-nav - Alessandro Carminati & Gabriele Paoloni, Red Hat

Monday September 16, 2024 12:35 - 12:55 CEST

Room 2.15 (Level 2)

In order to make functional safety claims on SW components, having a clear understanding of the underlying software architecture is crucial. However, if SW architectural documentation is missing, understanding how software operates and how its parts fit together can be challenging. For the Linux kernel and many other OSS SW, such documents are absent and instead, analysts must rely on code, which can be hard to read.
ks-nav is a tool designed to help in reverse engineering and understanding the code by generating diagrams that highlight the interactions between code elements and sub-elements.

ks-nav relies on binary images instead of source code analysis to get rid of the uncertainty introduced by configurations, compiler optimizations, and any other toolchain related issues. Additionally, using the MAINTAINERS file, it precisely pinpoints subsystems, enabling users to delve into their interactions with clarity.

This session focuses on:
* Why understanding the code is critical in FuSa activities;
* How ks-nav works, how it addresses the various challenges of analyzing the code;
* An example of how ks-nav can be used to support an expert-driven FMEA for a specific use case.

Cross Industry Demands and Collaboration Opportunities in Open Source for Safety Critical Systems - Philipp Ahmann, Robert Bosch GmbH & Olivier Charrier, Wind River

Monday September 16, 2024 14:15 - 14:55 CEST

Room 2.15 (Level 2)

The increasing computation power of embedded CPUs has revolutionized industries such as Automotive, Aerospace, or Industrial by enabling centralized and enhanced use cases, software-defined functionalities, and increased automation. The challenges of this increased complexity are often addressed by incorporating Open Source Software, particularly Linux, virtualization and RTOS. As these industries are heavily regulated by quality and safety-integrity standards, the certification of these highly complex systems becomes crucial.

Starting from the similarities and overlaps in system architecture design across use cases, this talk will explore the demands imposed by safety integrity standards in various industries. To develop these systems and adhere to required processes, the integration of tools and a high degree of automation is essential.

The authors show how Open Source projects bridge the gap between open source and safety-criticality, introducing tools and processes, and showcasing collaborative efforts in creating reproducible example system architectures. These systems can serve as a foundation for companies and projects adopting Open Source in safety-critical applications.

Real-time Scheduling Fault Simulation - Ben Dooks, Codethink

Monday September 16, 2024 14:15 - 14:55 CEST

Hall M1 (Level 1)

There is a lot of work around how to achieve good real-time on Linux, but not as much on how to simulate faults such as jitter in the system, deadline misses or other faults. Without this it is difficult to test how your application or entire system copes with these problems.

As part of work with a number of clients, especially in the safety sphere, questions have come up on how to test processes which rely on real-time scheduling. If we have a way of injecting faults we can reliably test error handling and other mitigations. Mitigations such as throttling, restarting or some measured shutdown of services.

We will go through some methods we evaluated for fault injection via both user and kernel space. How existing kernel features can be used and what needs to be done in the way of either configuring or extending kernel features. There will be discussion about how each method works and the comparative merits where overlaps exist.

We hope that this can help to promote thinking and improvements on how the scheduler and particularly real-time scheduling is tested under Linux.

Lightning Talk: Optimizing Kubernetes Multicluster Backup & Restore - Hường Đinh, Viettel Solutions

Monday September 16, 2024 14:25 - 14:35 CEST

Room 0.14 (Level 0)

In this presentation, I aim to address critical challenges in Kubernetes cluster management, particularly focusing on optimizing multicluster backup and restore processes using Velero. The current state of Kubernetes cluster management emphasizes the critical importance of implementing robust backup and restore processes. However, a challenge arises when dealing with multiple clusters, requiring the installation of Velero on each cluster, resulting in complex and resource-intensive multicluster Kubernetes environments. To address this issue, the proposed solution advocates for a centralized Velero installation, allowing for the backup and restore of individual clusters using their corresponding kubeconfig. The talk delves into the design architecture of multicluster backups, outlining how to integrate this approach with Velero's existing features. This innovative approach not only simplifies management but also optimizes resource utilization in a way that aligns with the evolving landscape of Kubernetes cluster operations. I aim for the audience to leave with actionable insights and a clear roadmap for implementing centralized backup strategies in their own multicluster setups.

How to Make Your Kubernetes Add-Ons Management Painless in Multi Cloud - Eleni Grosdouli & Gianluca Mardente, Cisco Systems

Monday September 16, 2024 15:25 - 16:05 CEST

Room 0.11-0.12 (Level 0)

One of the most powerful aspects of Kubernetes is its extensibility. But with flexibility comes complexity. Deploying Kubernetes add-ons extend its functionality, but with most platform engineers managing and maintaining multiple clusters across different environments comes the pain. Giving a breather to platform administrators will allow them to be more productive and creative, while enabling them to perform deployments easily, quickly and reliably. From a small home lab to large-scale production environments, keeping up with Kubernetes add-ons deployment and management in a consistent, reliable, and maintainable manner can be like trying to find Nemo on the CNCF landscape. In this engaging session, we will demonstrate: - How smoothly Flux synchronises Kubernetes resources - How to use different add-on formats, including Helm charts, raw YAML/JSON highlighting the Lua language template creation for advanced deployments and logical application - How to deploy Cilium as a CNI - How to deploy Kyverno policies to clusters based on their scope as templates Attendees will learn a new, easy and creative way of deploying applications whether on-prem or in the cloud.

Bringing Existing Open-Source Code into MISRA Compliance - Roberto Bagnara, University of Parma and BUGSENG

Monday September 16, 2024 15:25 - 16:05 CEST

Room 2.15 (Level 2)

Bringing an existing codebase into MISRA compliance is known to be a difficult, risky and time-consuming task. Yet, when a product needs a functional safety certification and rewriting the software is out of question, this is a necessity. Such an endeavor requires facing multiple tradeoffs and, consequently, lots of experience both on the codebase and on MISRA. The choices between deviating the guideline, and the (often, many) ways in which code may be changed and deviations may be formulated, are tough and with consequences that are not immediately evident. The situation is particularly interesting in the case of open-source software, where additional challenges have to be faced. In this presentation, we illustrate our experience and the several lessons learned while undertaking MISRA compliance work in open-source projects, most notably the Zephyr RTOS and the Xen hypervisor, both used in many embedded systems. Key take-home points include: effective deviation strategies and mechanisms; dealing with the MISRA C essential type model (guidelines related to that account for many of the violations in existing codebases); interaction with open-source communities.

From Hardware to Linux - Stefan Eichenberger, embear GmbH

Monday September 16, 2024 15:25 - 16:05 CEST

Hall C (Level 2)

This presentation will show a step-by-step guide from hardware design to a fully functional Linux system. Initial considerations in the hardware design phase will help simplify the bringup. This includes designing for testability and incorporating features that make debugging easier, such as having accessible test points and providing instrumentation, such as a serial console and a JTAG interface. The next phase involves the bootloader, which is the first software component to run on the system. At this stage, we can use JTAG for early debugging to get some text output and eventually a console. The transition to the Linux kernel involves strategies that may include using JTAG again for early kernel debugging, followed by using printk and KDB for later diagnostics. The final phase involves the root file system and userspace tools that help bring up the rest of the peripherals. This final section of the presentation shows some userspace diagnostic and debugging tools for successfully getting a Linux-based system up and running.

Fine-Grained Policies RBAC with OpenFGA - José Carlos Chávez, Okta

Monday September 16, 2024 16:20 - 17:00 CEST

Room 0.11-0.12 (Level 0)

The fine-grained nature of cloud native deployments requires fine-grained authorization at each component. However, this may require security policies to be centrally defined and the configurations reflecting them to be defined in each microservice to enable uniform, consistent enforcement across the entire system which is hard to model and maintain. OpenFGA is an open source solution to Fine-Grained Authorization that applies the concept of Relationship-based access control (ReBAC) where a subject's permission to access a resource is defined by the presence of relationships between those subjects and resources. It was designed for reliability and low latency at a high scale. This talk will offer an overview of OpenFGA, ReBAC and its advantages over more traditional RBAC and ABAC in the context of Zero Trust.

Embedded Audio Policies Made Easy with WirePlumber - George Kiagiadakis, Collabora

Monday September 16, 2024 16:20 - 17:00 CEST

Hall B (Level 2)

Building robust audio policies on embedded systems that integrate well with upstream APIs and components such as PipeWire and PulseAudio has been a challenging task for a long time. In many implementations, custom hardware DSP management components are built, bypassing existing upstream functionality, making integration and maintenance harder than they need to be. In this talk, George will explain how many of these difficulties can be overcome by integrating management directly into WirePlumber, the default session manager of PipeWire, and how existing functionality can be factored in to build complex solutions with ease. Emphasis will be given also on how recent developments in WirePlumber have improved this particular use case.

Monday September 16, 2024 16:20 - 17:00 CEST

Hall C (Level 2)

More and more applications of embedded linux systems require them to ensure that only trusted software is started on the device. This means that verified boot procedures need to be employed to verify the software running on the device. This talk will highlight the necesssary components to cryptographically verify the bootloader, kernel and filesystem. It will also show how these components can be integrated using the OpenEmbedded build system. Bootloader verification will be covered by providing examples to use the signing.bbclass in Yocto in conjunction with the NXP CST tool to sign a bootloader, kernel verification is covered by a to be upstreamed fitimage class and filesystem verification will be shown with a dm-verity class example for Yocto. Additionally the talk will highlight common pitfalls when deploying locked down embedded systems encountered during project work. We will also cover the case of using GPLv3 licenses on locked down devices.

What Makes a Good, or Bad, Open Source Experience?! - Ildiko Vancsa, Open Infrastructure Foundation & Philip Robb, Ericssson Software Technology

Monday September 16, 2024 16:20 - 17:00 CEST

Room 0.94-0.95 (Level 0)

Open source means a lot of things to a lot of people. That may be why it’s one of the most misunderstood and misused terms in tech and related ecosystems. In fact, if you ask ten different people in tech “what is open-source?”, you are likely to get ten very different answers. We know, we’ve done it! So what makes a “good” or “bad” experience for users and participants in open-source projects? Ildiko and Phil have set out to answer this question with their “My Open Source Experience” podcast. They are talking to seasoned professionals and newbies, to understand the challenges and successes they’ve experienced so far. Questions they ask include: Was it the code, the community, or the person's employer that made their experience better or worse? How did people navigate difficulties? What are “best practices” to achieve “success” however that is defined for individuals, their organization, and/or their community? In this talk Ildiko and Phil share some of the most interesting take-aways from their conversations with podcast guests as well as from their own open source journeys, and invite the audience to join the conversation and share their experiences.

Monday September 16, 2024 16:20 - 17:00 CEST

Room 0.49-0.50 (Level 0)

This session covers two major topics: Firstly, the significance of an open source management system in the context of IP management for heavily software-dependent companies. Managing open source dependencies is a key pain-point, since so much of modern software development depends on it. Yet only a small number of people truly understand open source beyond “just the code”. Although a company's heavily intellectual property (IP)-involved departments deal with IP management everyday, they are oblivious to open source software. This talk suggests ways to translate the ‘open source talk’ and make these departments your comrades in arms. Secondly, the speakers introduce the OpenChain Specification 2.1 (ISO/IEC 5230:2020) on open source license compliance, aka a framework and a blueprint for how to translate open source management into IP management. This session gives you the tools to turn the view of open source from a potential liability to a valuable asset. The speakers pull from their experience working in IP heavy weights such as Ericsson (more than 60.000 granted patents globally) to put the above into context and give example of Ericsson’s ongoing journey in this area.
