CIP Core supports Debian 11-based reference images

By Announcement, Blog, In the News

Author: Kazuhiro Hayashi,  CIP Core Team Chair, Toshiba

The Civil Infrastructure Platform (CIP) project has five Working Groups – Security, Kernel, Testing, Software Update and CIP Core. The CIP Core Working Group [1], which was launched in 2019, is responsible for developing, testing and maintaining tools to generate CIP Core reference file system images. We are excited to announce that the working group now supports Debian 11-based reference images. 

The CIP Core images consist of CIP kernel and Debian base systems and provide run-time environments that work with CIP reference hardware [2. ] This library of images is the foundation for CIP developers to enhance new features, test existing functions, and maintain them for the long-term. CIP users can evaluate the features with the reference images in relation to their use cases.

The isar-cip-core [3] now supports 5.10 based CIP kernel [4] and Debian 11 bullseye packages. Isar-cip-core is a set of extensions for isar (an image generation tool) to support CIP reference hardware and other features including, but not limited to, security and software updates. Debian 11 bullseye is currently the “stable” version and will be maintained by Debian project and the LTS project until June 2026. After June 2026, the Debian Extended LTS project will inherit its maintenance. The 5.10 CIP kernel is being maintained by the Linux kernel community as a long term release kernel until Dec. 2026. After this, CIP will maintain it until Jan 2031.

By supporting 5.10 CIP kernel + bullseye based CIP Core images, users can use the latest stable versions of CIP kernel and userland with all the CIP reference hardware[2], some of which are only supported by the 5.10 kernel. 

The CIP Security Working Group[5] is targeting version 5.10 CIP kernel and the bullseye based CIP image to achieve IEC-62443-4-x certification. The CIP Software Updates Working Group[6] is actively improving secure software update mechanisms by SWUpdate and secure boot and expanding devices where the features have been supported, with the latest version of CIP Core image as well as the previous.

The CIP Core Working Group plans to continue to introduce more useful features like above to the 5.10 kernel + bullseye based image and maintain them in cooperation with other working groups and related open source software communities. Contact us via the cip-dev mailing list for feedback, questions, or discussions.







CIP Expands Work on SLTS Kernel Maintenance

By Announcement, Blog, In the News

The Civil Infrastructure Platform project ( – released the first 5.10-based version of its super-long-term stable (SLTS) kernel. The 5.10-based release made official the third CIP kernel series available after 4.4-cip and 4.19-cip. It demonstrates how CIP remains committed to maintaining all SLTS versions for a minimum of 10 years after the original release.

With the recent discontinuation of the 4.4 LTS kernel by its maintainer Greg Kroah-Hartman, the CIP project now requires organized backports to one of its kernels for the first time, independently of the LTS project. The CIP kernel team already expanded its capacity last year and is well prepared to handle this task.

The CIP kernel developers will remain  involved in the review process of patches targeting related LTS kernels. CIP is actively engaged in enhancing the test infrastructure for the Linux Kernel, both through its work on the CIP SLTS Kernels and CIP’s participation in the KernelCI project.

About The Civil Infrastructure Platform (“CIP”)

The Civil Infrastructure Platform (“CIP”) is a collaborative, open source project hosted by the Linux Foundation. The CIP project is focused on establishing an open source “base layer” of industrial grade software to enable the use and implementation of software building blocks in civil infrastructure projects. Currently, civil infrastructure systems are built from the ground up, with little re-use of existing software building blocks.

The CIP project intends to create reusable building blocks that meet the safety, reliability and other requirements of industrial and civil infrastructure. By establishing this ‘base layer’, CIP aims to:

  • Speed up implementation of civil infrastructure systems;
  • Build upon existing open source foundations and expertise without reinventing non-domain specific technology;
  • Establish (de facto) standards by providing a base layer reference implementation;
  • Contribute to and influence upstream projects regarding industrial needs;
  • Motivate suppliers to actively support these platform / provide an implementation; 
  • Promote long term stability and maintainability of the base layer of code; and
  • Adopt the security standard IEC 62443

With respect to project governance, a Governing Board is responsible for financial matters while the Technical Steering Committee oversees the technical direction of the project.

CIP Testing Working Group

By Blog, Work Group

Today, the Civil Infrastructure Platform has multiple requirements that need to be maintained. This is where the CIP Testing Work Group (TWG) comes in. The TWG configures and manages the automated test infrastructure for the CIP project and ensures all systems are operating correctly. Currently led by Chris Paterson (patersonc), the TWG’s main focus is on maintaining the LAVA instance that the project uses. Overall, the TWG provides the infrastructure needed to test the various CIP projects such as the Super Long Term Support (SLTS) Kernels and CIP-Core reference filesystems.

The CIP project aims to provide support for the Linux Kernel for a comparatively long time. Over time the amount of testing required will keep increasing as the project grows, so it is important to have as much of that testing as automated as possible. Without automation, the cost of testing would be prohibitive.

Under the hood 

Our Continuous Integration (CI) setup is driven by GitLab CI/CD which dynamically boots up AWS EC2 on-demand instances for our build jobs using our gitlab-cloud-ci tool.

Test jobs are also created and submitted to our LAVA instance, where they are run on QEMU virtual machines and on physical devices.

The GitLab CI pipelines that we use to build/test the Kernel are hosted in a separate GitLab repository.

Currently, CIP has two LAVA master instances (production & staging) and 5 LAVA workers (Cybertrust, Denx, Mentor, Renesas & “Chris” (staging)) in use, hosting a total of 284 devices.

The current device status can be viewed at

We support all of the CIP reference platforms. We are working to expand the number of devices available, increasing reference platform availability whilst reducing test times.

Testing WG and the ecosystem 

This group is a critical part of the overall CIP ecosystems, working with other CIP WGs as well as external open source projects. For example, CIP Testing works with all of the other CIP projects and working groups as most, if not all require the ability to test their software. Outside of CIP the testing group collaborates with other open source projects such as KernelCI, LAVA and Linaro’s test definitions. CIP also builds and boot tests each stable Linux Kernel release candidate in a number of different configurations.

On the Horizon

CIP has recently started work on their third SLTS Kernel, based on v5.10.y, which means that our automated testing needs to be expanded accordingly.

On the roadmap is collaborating further with the KernalCI project on testing management. The TWG is currently working with the KernelCI project to set up CIP’s own instance of KernelCI’s back/front-end. This will allow the project to better manage its testing and automatically process and check the results for any regressions. The front-end GUI that KernelCI provides is much better for reviewing test results then the setup CIP is currently using.

Get Involved

We are always happy to collaborate with others to expand and improve our setup, whether it’s upgrading the core infrastructure or simply adding support for more test cases.

Reach out to us on IRC (Freenode #cip) or via the cip-dev mailing list.

More information on the activities of the TWG can be found on the CIP Wiki.

CIP to Embark on Kernel 5.10 Development for SLTS

By Announcement, Blog

Starting early next year Civil Infrastructure Platform will start development for the next major super long-term support (SLTS) kernel version based on upstream kernel 5.10.

This will be the third SLTS kernel maintained by CIP for the extended time frame of 10 years. The SLTS kernels differentiate from regular LTS releases in that they accept certain hardware-enabling backports of upstream accepted changes. By having the latest kernel features and device supports, the new SLTS kernel will give a new starting point for long term support. This will benefit users who are planning to embark on new industrial-grade device developments or Board Support Package (BSP) developments.

If you are relying already on CIP SLTS 4.4 or 4.19 kernels or plan to make use of the upcoming version, please consider joining the project to ensure its sustainability and help expanding SLTS support also in the future. Being a member furthermore allows to influence the project direction, the choice of reference hardware and kernel configurations that will be supported and tested.

By starting the SLTS kernel development, CIP would be ready to align with a new Debian release which is expected in 2021. The Debian Project aims to provide Linux-based operating system, Debian, to be widely used with long-term support. This enables CIP to take advantage of their activities to achieve CIP’s goal. 

End-users of CIP include systems for electric power generation and energy distribution, oil and gas, water and wastewater, healthcare, communications, transportation, and community management. These systems deliver essential services, provide shelter, and support social interactions and economic development. They are society’s lifelines, and CIP aims to contribute to and support these important pillars of modern society. Developing the next major SLTS kernel version helps CIP continue on its goal to create an interoperable open source software platform that is secure, reliable and sustainable for at least 10 years.

CIP Kernel Team: Helping CIP Sustain Industrial Grade Systems

By Blog, Work Group

The Civil Infrastructure Platform has several work groups that ensure things keep running. Below is a Q and A with the CIP Kernel Team. 

1. What is CIP Kernel Team (What does this team work on, what issues does it solve)

While the CIP project aims to establish an open source base layer (OSBL) of industrial grade software to enable the use and implementation of software building blocks for civil infrastructure, CIP Kernel Team is responsible for Linux kernel in OSBL to sustain industrial grade systems or devices during their life cycles.

2. What is the primary goal of this team?

The goal of the team is to provide CIP kernels with more than a ten year maintenance period by fixing versions to fulfill the required level of reliability, sustainability, and security.

3. What is the development principle of CIP?

CIP adopts the upstream first as our development principle. The “Upstream First” principle allows patch commits only if those patches are already in the upstream. By following this principle, if a desired patch is not in the upstream yet, this patch should be accepted by the upstream at first. Therefore, it may take time to introduce the desired patch to our project.

But, it enables us to share our outputs with the upstream.  At the same time, the risk of conflicts can be eliminated.

CIP is aiming to sustain target systems and devices during their life cycles which are very long by their nature. So the Upstream First principle is essential to achieve our goal. 

4. What is “Upstream First” for the Kernel Team?

For the CIP kernel team, upstreams are Linux mainline and LTS. The team collaborates with upstream projects. Before using their outputs, the team upstreams what the team has and doesn’t keep them locally. 

As marked 1, “Contribution” is our first action. Feature upstreaming is done by CIP member developers. On the other hand, the CIP Kernel Team contributes to upstream in a more general manner. The team developed open source tools in order to work on contributions effectively..

As marked 2, “Use” is the second action. The team uses LTS kernels to release CIP SLTS kernels. For those releases, automated testing plays a very important role. Therefore the  CIP kernel team is closely working with the CIP testing team.

As marked 3, “Integrate” is the third action. By integrating those SLTS kernels with CIP Core packages and additional packages, industrial systems or devices can be developed and maintained.

5. How does the team use LTS kernels?

The team uses LTS for CIP SLTS kernel bases. 

CIP SLTS kernels are based on LTS 4.4 and 4.19. The first releases of SLTS 4.19 and 4.19rt were done in 2019. The team plans to maintain them until 2029 for ten years. The first releases of SLTS 4.4 and 4.4rt were done in 2017, and likewise the team supports them for ten years till 2027.

Both LTS 4.4 and 4.19 are maintained for 6 years by the LTS project. So, the remaining 4 years will be maintained by the CIP Kernel Team.

6. How can CIP kernels be used?

By integrating the SLTS kernels with CIP Core packages and additional packages, industrial systems or devices can be developed. 

CIP refers to Debian for userland packages. If you would like to use Debian source packages, you can use Yocto/Poky as a build system. 

CIP core packages contain tens of packages which may not be sufficient for the development of end products. So, you can add necessary packages from Debian by writing recipes.

7. What has this team accomplished so far?

Currently SLTS 4.19 is released twice a month and 4.4 is once a month. SLTS 4.19-rt is once a month and 4.4-rt once every two months.

So far the team has steadily released CIP SLTS kernels by following release frequencies below. 

(as of June 7, 2020)

8. What are some future goals?

The team made major releases in 2017 and 2019. So, a major release frequency is once per two years so far. Another two years is going to pass, and Year 2021 is approaching. So, the team started to discuss new SLTS kernels.  

9. How can people get involved?

Session Highlight: Secure Boot and Over-the-Air Updates – That’s Simple, No?

The Civil Infrastructure Platform is thrilled to be sponsoring the Linux Foundations’ OpenSource Summit North America Event. In addition to having a virtual booth, CIP reps will be giving several talks as well as hosting the CIP Mini-Summit.  

On June 30 from 9:30 to 10:20 am CT,  Jan Kiszka with Siemens AG will be giving a talk called, “Secure Boot and Over-the-Air Updates – That’s Simple, No?”  

Check out talk details below and read on to learn how to register for the event. 

Locking down embedded Linux devices via secure boot is almost solved these day. Combining this with rollback-capable over-the-air updates shouldn’t be hard then. But as often, the devil is in the detail. When he comes out, you can easily end up with an insecure system or one that does not update anymore. Or both.

In this talk, we will present patterns and tools for secure OTA system updates that are being developed in the Software Update Workgroup of the Civil Infrastructure Platform project. We will introduce an OTA pattern consisting of redundant update images that are deployed and managed by SWUpdate and switched by a boot loader. We will discuss the options and implication of securing those images, for the boot process as well as the runtime of the images. Then we will walk through UEFI-based secure boot processes, explain shortcomings of commodity boot loaders are and where to use the embedded boot loader EFI Boot Guard instead. Finally, we will also have a look at plain U-Boot-based setups, discuss if its new UEFI mode can help to unify architectures and explain what to do when it is not available.
