Safe Systems with Linux (Video)

By Ambassadors, Blog, Industry Conference, Linux Foundation

As Linux is increasingly deployed in systems with varying criticality constraints, distro providers are expected to ensure that security fixes in their offerings do not introduce regressions for customer products that have safety considerations. The key question arises:

  • How can they establish consistent linkage between code, tests, and the requirements that the code satisfies?
  • Which open source tools and specifically for Linux exist to support traceability in order to comply with standards such as ASPICE, ISO26262 or ISO21434?

This video from Open Source Summit Japan – presented by Philipp Ahmann, Sr. OSS Community Manager, Etas GmbH; and Kate Stewart, Vice President of Dependable Embedded Systems at the Linux Foundation – addresses critical challenges in requirements tracking, documentation, testing, and artifact sharing within the Linux kernel ecosystem. Functionality has historically been added to the kernel with requirements explained in the email justifications for adding, but not formalized as “requirements” in the kernel documentation. While tests are contributed for the code, the underlying requirement that the tests satisfies is likewise not documented in a consistent manner. This and further topics will be discussed. Additionally, the results from the “Safe Systems with Linux” micro conference at Linux plumbers will be summarized.

Application of the Upcoming SPDX Safety Profile (Video)

By Blog, Critical Software Summit

Creating and maintaining a safety critical project comes with a lot of challenges. A central issue is keeping your documentation, starting from planning and guideline documents, down to requirements, safety analysis, reviews and tests, consistent and up to date. These artefacts often have their own lifecycle and are natively managed in different tools, with usually great traceability capabilities regarding dependencies between these artefacts as long as you stay within one tool or within a (usually propriety) tool family of one single tool vendor. Currently the resulting traceability gaps between these tools are handled either by the popular engineering tools like MS Excel or methods like “search for identical names”, depending highly on manual maintenance.

Using SPDX relationships, the upcoming Safety Profile in SPDX 3.1 will provide a model to represent all these dependencies as a knowledge model that can be used both to analyze possible impacts after a change (be it because of a security update or functional variants of your product), provide evidence of completeness and compliance as a Safety SBOM or simply keep track of your product variants.

Nicole Pappler, Senior Safety Expert at AlektoMetis, gave a presentation, “Application of the Upcoming SPDX Safety Profile,” at the Critical Software Summit, which took place at Open Source Summit Europe in September.  Check out the presentation here.

A recap of Open Source Summit Europe (Vienna)

By Blog, Industry Conference

Written By Will Stonier, Content Marketing Executive at Codethink and Paul Albertella, ELISA Project TSC member, Chair for Open Source Engineering Process Working Group and Consultant at Codethink

This blog originally ran on the Codethink website. For more content like this, click here. 

Vienna hosted this year’s European Open Source Summit (OSSEU). Several team members travelled to the ‘City of Music’ to participate in talks and discussions, eat traditional Austrian food, and discuss the future of open source and Linux. The venue was the Austria Center, located in the city’s North East.

OSSEU is one of the bigger events in the open source calendar, with thousands of attendees and a wide array of talks and vendor stands. Moreover, there is a growing number of micro-conferences focussing on topics and domains under the open source umbrella.

Two Codethings presented at OSSEU. Ben Dook’s talk, ‘Real-time Scheduling Fault Simulation,’ examined some methods Codethink has used for fault injection via both user and kernel space in our client work. As part of our work within critical safety, questions frequently arise on how to test processes that rely on real-time scheduling.

Sudip Mukherjee’s talk, ‘Testing, a Journey from Testing Kernels to Testing Debian and Yocto,’ focused on how Sudip started testing the Linux Kernel in a personal capacity and the status of kernel testing as part of his role at Codet hink. You can watch Sudip’s talk here:

 

However, the conference had something for everyone. For those of the team who focus on open source software in safety and security systems, there was the Critical Software Summit on the first day, and relevant talks on the Embedded Linux track, including one on ‘Linux in Space’ and another on spatial safety in Linux (two very different topics!).

The conference also provided an excellent opportunity for team members to explore Linux kernel topics more deeply. Paul Albertella noted that a talk about power management features was especially helpful, as it drew his attention to the power management of individual devices at runtime as distinct from the system as a whole, helping him navigate tricky nuances of his own laptop!

Here’s what Joshua Zivkovic had to say about Open Source Summit Europe:

“Linux Foundation events, like Open Source Summit EU, provide a way for every corner of the open source world to come together to share innovations, expertise, and experiences amongst the endless number of microcosms of open source.”

Finally, the conference caught the headlines (and caused chatter in the Codethink office) with the announcement that real-time Linux is now officially part of the kernel. This is exciting news, and we’ll be watching how this progresses.

We’ll see you next year!

Critical Software Summit 2024

By Blog, Linux Foundation, News

The Open Source Summit Europe, which takes place on September 16-18 in Vienna, Austria, is packed with technical content. It is the premier event for open source developers, technologists, and community leaders to collaborate, share information, solve problems, and gain knowledge, furthering open source innovation and ensuring a sustainable open source ecosystem.

As a conference umbrella, Open Source Summit is composed of a collection of events covering the most important technologies, topics, and issues affecting open source today. The Critical Software Summit is one of those microconferences.

As open source is found more and more in safety-critical products and infrastructure, the need to ensure dependability and reliability has increased. This event gathers developers focused on solving these issues, to figure out how we can increase the confidence of using OS projects in safety, mission, and business-critical applications.

Several of ambassadors, contributors and leaders from the ELISA Project will be giving presentations on Monday, including:

Creating and maintaining a safety critical project comes with a lot of challenges. A central issue is keeping your documentation, starting from planning and guideline documents, down to requirements, safety analysis, reviews and tests, consistent and up to date. These artefacts often have their own lifecycle and are natively managed in different tools, with usually great traceability capabilities regarding dependencies between these artefacts as long as you stay within one tool or within a (usually propriety) tool family of one single tool vendor. Currently the resulting traceability gaps between these tools are handled either by the popular engineering tools like MS Excel or methods like “search for identical names”, depending highly on manual maintenance.

Using SPDX relationships, the upcoming Safety Profile in SPDX 3.1 will provide a model to represent all these dependencies as a knowledge model that can be used both to analyse possible impacts after a change (be it because of a security update or functional variants of your product), provide evidence of completeness and compliance as a Safety SBOM or simply keep track of your product variants.

In Safety Critical applications it is mandatory to ensure Sw Requirements traceability to Sw Specifications, Test Cases, Test Results, Bugs and more.
The process leading to this goal is usually complex and time-consuming and it is essential to understand the state step by step and highlight what remains to be done.
Moreover, for the intrinsic nature of a software project, we need to ensure traceability and test verification following any evolution in the ecosystem of the project.

BASIL The FuSa Spice, is an open source sw that provides a quality management solution aimed to address the above mentioned challenges for SW developments that are code driven and equally for the ones requirements driven.

We will see how to implement in BASIL Sw Requirements traceability to the source Code and to existing upstream Test Cases, how to execute them, how to navigate Test Results and artifacts and how to link failures to a bug in a bug tracking system.

We will also go into the details of a pipeline implementation based on the BASIL HTTP Api to understand how changes in one or more work items can be managed through automation with the goal of implementing a continuous certification framework.

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.

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.

The full schedule for the Critical Software Summit Schedule can be viewed here. Register here to attend in-person. Virtual registration is not required to access the event live stream. All conference sessions will be live-streamed to the Linux Foundation YouTube channel with freely available access during the event. Live stream links for each session can be accessed from each session listing in the schedule. More information is coming soon.

ELISA Milestones & What’s next

By Blog, Working Group

As Linux continues to be a key component in safety-related applications, Enabling Linux in Safety Applications (ELISA) is an open source project that aims to create a shared set of tools and processes to help companies build and certify Linux-based safetycritical applications and systems. Launched in February 2019, ELISA works with Linux kernel and safety communities to agree on what users should consider when using Linux in safety-critical systems.

In 2023, ELISA increased the technical resources created for the Linux community, including a Seminar Series of no-cost, on-demand videos that provide overviews of a special focus and project workshops for community members who are interested in advancing the milestones and goals of the project. The ELISA Seminar series hosted sessions that many organizations hosted, including Red Hat about an open source tool, tentatively named Basil, for tracing requirements, code, and tests; AMD about Xen safety certification; the Linux Foundation with AlektoMetis about automating adherence to safety profiles after fixing vulnerabilities; and the Boeing Company about DO-178C Level D certified Linux and NASA.

Two in-person workshops in Berlin and Munich brought together industry thought leaders and open source community members to discuss all safety-related issues, challenges, and next steps for the project. The project has several dedicated Working Groups (WGs) that provide resources for system integrators to apply and use to qualitatively and quantitatively analyze their systems:

  • Aerospace WG is busy surveying aerospace’s state of the art on using Linux and the associated certification approach and equivalent Design Assurance Level and identifying the challenges to adopting Linux in aerospace and candidate use cases using Linux.
  • Architecture WG is adopting the ks-nav tool set to implement and expand the STPA approach within the kernel.
  • Linux Features WG analyzed the potential and challenges of real-time safety-critical systems and presented their work at the Embedded Open Source Summit.
  • Medical Devices WG set out to discover the Linux kernel subsystems that OpenAPS used, shared key findings, and upstreamed the workload tracing guide.
  • Open Source Engineering Process WG documented how to apply a safety analysis process based on STPA suitable for Linux and other OSS use.
  • Systems WG shared the work on creating a reproducible example system consisting of Linux, Xen, and Zephyr on real hardware at the Linux Plumbers Conference.
  • Tools WG has enabled Continuous Integration.

To kick off the new year, ELISA Working Group leads will be giving an annual update next week. The updates will include the following topics:

  • A recap of milestones in 2023
  • Current focus and activities
  • What’s coming up in 2024 and areas and opportunities for collaboration
  • Onboarding resources and how to get involved

This is a great opportunity to get up to speed with what each of the Working Group is working on and how you can participate and contribute this year. For more details and to register to attend please click here: https://elisa.tech/event/working-group-annual-updates/.

Putting Linux into Context – Towards a reproducible example system with Linux, Zephyr & Xen 

By Ambassadors, Blog, Industry Conference

Last week, developers from around the world traveled to Richmond, Virginia for the annual Linux Plumbers Conference. Hosted at the Omni Richmond Hotel on November 13-15, the event was mostly in-person with a live-streaming element for those who couldn’t make it.

Philipp Ahmann, Product Manager for Embedded Open Source at Robert Bosch GmbH and Chair of the ELISA Project Technical Steering Committee (TSC), was at the event and gave presentation titled, “Putting Linux into Context – Towards a Reproducible Example System with Linux, Zephyr & Xen.” You can find his presentation video and PPT  below:

 

Linux Plumbers Conference – ELISA PresentationDownload

Demos on embedded systems using Linux are plentiful, but when it comes to reproducing them, things get complicated. Additionally, on decent embedded systems Linux is only one part of the system and interacts with real-time operating systems and virtualization solutions. This makes reproduction even harder.

Within the Linux Foundation’s ELISA project, we started to create a reproducible example system consisting of Linux, Xen, and Zephyr on real hardware. This is the next step after we achieved a reproducible system with a pure Linux qemu image.

The idea is to have documentation, a continuous integration including testing, which can be picked up by developers to derive and add their own software pieces. In this way they should be able to concentrate on their use case rather than spending effort in creating such a system (unless they explicitly want this). We also show how to build everything from scratch. The assumption is that only in this way it is possible to get a system understanding to replace elements towards their specific use cases.

We had challenges finding good hardware, tools, freely available GPU drivers and more and we are still not at the end. A good system SBOM is also creating additional challenges, although leveraging the Yocto build system has provided some advantages here.

While we are setting up the first hardware with documentation from source to build to deployment and testing on embedded hardware, we aim to have at least two sets of all major system elements like Linux flavor, a choice of virtualization technique, real-time OS and hardware. Only when software elements and hardware can be exchanged, we identify clear interfaces and make a system reproducible and adoptable.

Open Questions are:

  • What will be a good next hardware to extend this PoC scope?
  • Where do open source, security, safety, and compliance come best together?
  • Which alternative real-time operating systems and virtualization should be incorporated?

ELISA Summit: Intro & Technical Strategy (Video)

By Blog, ELISA Summit

An estimated 185 people registered for the ELISA Summit, which took place virtually on September 7-8 to gather Linux community members and attendees from around the world. The event, which featured 15 sessions and 20 speakers, was open to anyone involved or interested in defining, using, or learning about common elements, processes, and tools that can be incorporated into Linux-based, safety-critical systems amenable to safety certification. Members of the ELISA Project community, presented best practices and overviews on emerging trend and hot topics to using open source software in safety-critical applications and detailed working group updates.

We’ll be featuring event videos in blogs each week. Today, we focus on one of the most popular sessions presented by Kate Stewart, VP of Dependable Embedded Systems at the Linux Foundation, and Shuah Khan, Kernel Maintainer and Fellow at the Linux Foundation. They kicked off the Summit with a session titled, “Welcome & Strategy,” where they gave an overview of ELISA Project and its Technical Strategy. This video is an introductory session for new comers and ELISA members that aren’t regular participants in the Working Groups.
