They allow separation of applications, updates independent of the host system, isolation of hardware and more. During this hands-on class we will explore: * Introduction into containers and how they differ from other virtualization techniques * Building a container host system with the Yocto Project and launching a container * Building containers with the Yocto Project from Yocto Project packages * Building containers from upstream repositories e.g. Docker.io with the Yocto Project using Podman and Docker compose files yocto-project-summit-2024-12-57725-building-a-containerized-system-with-the-yocto-project Hands on Lab Rudolf J Streif en Containers are nowadays commonly used in enterprise computing. Embedded systems are catching up as developers are looking to leverage the advantages for them. With the Yocto Project there are two principal approaches to building containers for a host system: * Build the container from packages also built by the Yocto Project * Build the container from upstream registries like a public (e.g. Docker.io) or private repository While the former approach leaves everything under control of the Yocto Project (licensing, software bill of materials, secruity/CVE), the latter approach allows to leverage other work and integrate it with a system built by the Yocto Project. Podman provides an alternative to Docker and Docker service for building containers.

It emphasizes the importance of security and addresses how Yocto CVE analysis, integrated with Jenkins and the warning-ng plugin, can be effectively used to identify and mitigate vulnerabilities. Additionally, the talk discusses how regular updates of components not only help track vulnerabilities but also play a crucial role in providing long-term support for products. yocto-project-summit-2024-12-56688-security-upstream-and-opensource-cd-ci Intermediate Track / Presentation Michael Nazzareno Trimarchi en Best Practices for Yocto Project with LTS Components and Security The Yocto Project is a powerful framework for creating custom Linux-based operating systems. To ensure stability, security, and long-term support, it's essential to adopt best practices when working with Long Term Support (LTS) components for the kernel, bootloader, and Yocto Project itself. LTS Components: A Foundation for Stability LTS components are designed to receive maintenance updates and security patches for an extended period. By using LTS versions of the kernel, bootloader, and Yocto Project, you can benefit from: Improved Security: Regular updates address vulnerabilities, enhancing the overall security posture of your system. Long-Term Support: LTS components ensure that your product can receive maintenance and support for a significant duration. Yocto CVE Analysis with Jenkins and warning-ng To effectively manage security vulnerabilities in Yocto Project builds, integrating CVE analysis with your development workflow is crucial. Jenkins, a popular continuous integration/continuous delivery (CI/CD) server, can be combined with the warning-ng plugin to automate this process. Steps involved: Configure Jenkins: Set up a Jenkins job to build your Yocto Project image. Integrate warning-ng: Install the warning-ng plugin and configure it to scan the build output for security warnings. Analyze CVE Reports: Use tools like the CVE Details database to cross-reference the identified warnings with known vulnerabilities. Prioritize and Address: Assess the severity of the vulnerabilities and prioritize their resolution. Update Components: If necessary, update the affected components to address the vulnerabilities. Beyond Vulnerability Tracking Regularly updating components, even those without known vulnerabilities, is essential for several reasons: Staying Current: Updates often introduce new features, performance improvements, and bug fixes. Future Compatibility: Keeping components up-to-date ensures compatibility with future hardware, software, and security standards. Proactive Security: Updating components can help prevent potential vulnerabilities that may be discovered in the future. By adopting best practices for Yocto Project development, including the use of LTS components and effective security measures, you can create more stable, secure, and long-lasting products. Integrating CVE analysis with Jenkins and the warning-ng plugin provides a robust framework for identifying and addressing vulnerabilities. Additionally, regularly updating components not only helps track vulnerabilities but also ensures that your products remain supported and compatible over the long term. false Slide release 1.2 https://pretalx.com/yocto-project-summit-2024-12/talk/HAD9XJ/ https://pretalx.com/yocto-project-summit-2024-12/talk/HAD9XJ/feedback/ kirkstone Talk 2024-12-04T14:35:00+00:00 14:35 00:30 The Yocto Project VS Code extension stands at a crossroads between two worlds: embedded Linux and web development.

While not common, there are instances where it becomes necessary to modify other file types, such as .inc or .bbclass, which do not offer an equivalent append mechanism. This session will summarize various strategies for effectively handling these file types when patching cannot be avoided. yocto-project-summit-2024-12-57466-patching-unpatchable-files Intermediate Track / Presentation Anna-Lena Marx en In my recent presentation [1] [2] at the Yocto Developer Day in Vienna, I mentioned using the KAS patch mechanism for minor modifications to files like .inc or .bbclass, where the Yocto internal overwriting mechanism via .bbappend files does not apply. Initially intended as a helpful side note on how I navigated a few unique situations, this part quickly escalated into the most discussed segment of the talk. Half of the attendees I spoke with found it valuable, while the other half expressed strong objections. In this follow-up session, I aim to dive deeper into the complexities of working with these “unpatchable” files and explore the following key questions: - In which situations is patching valid? - What strategies and approaches —both well-known and lesser-known— are generally available? - Which strategy is best suited for different scenarios and use cases? In conclusion, this talk aims to present and document various strategies for addressing the challenge of “patching unpatchable files” and to encourage discussions on best practices.
