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.
The Civil Infrastructure Platform is excited to participate in this year’s Open Source Summit EU/ Embedded Linux Conference EU!
The Open Source Summit series always provides unique opportunities to learn and connect, even when we can’t be in the same space together. We are looking forward to this year and all the ways to come together with the broader open source community.
Interested in catching up on the latest with CIP at the event? We have you covered! Through talks, our booth, Slack, and our CIP Mini Summit, there are a variety of ways to learn more about CIP.
At this year’s OSS EU, we are excited to have four CIP related talks on the schedule
The CIP Mini-Summit is a 90-minute, single-track event on the topic of industrial open source system which is based on Linux. The main goal of this event is to provide technical details and an overview to develop an industrial-grade CIP open source base layer. Sub-groups of CIP will talk about current development activities as well as future plans. Attendees will get to know how their products can leverage CIP’s SLTS(Super Long Term Support) to develop Industrial grade products.
Topics to be covered:
State of Civil Infrastructure Platform
CIP Kernel Team Activities towards Super Long Term Support
Status update for testing within CIP
CIP Security towards achieving industrial-grade security
To register for the CIP Mini-Summit, add it on to your Open Source Summit + Embedded Linux Conference Europe registration.
As a sponsor of the event, we will have an event “home base” for all things CIP. Stop by our booth for more information on the project and ways to get involved.
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.

Session Highlight: CIP Installed: Sustainable Software Stacks in Long-living Products
Civil Infrastructure Platform is excited to participate in the Linux Foundations’ OpenSource Summit North America Event. We are showing up in a variety of ways, as a sponsor, with several sessions and hosting the CIP Mini-Summit.
Check out talk details below and read on to learn how to register for the event.
Since the Civil Infrastructure Platform project launched in April 2016, we work with other open source communities to develop a super long-term supported (SLTS) open source “base layer” of industrial grade software that enables the implementation of building blocks in civil infrastructure projects. Long-term sustainability becomes a more major issue for not only industrial IoT systems, such as power plants, traffic lights, communications and weather systems, but also consumer IoT systems such as automotive and smart homes. In this talk, we will show the latest results of the CIP community in first half. Then we move to introduce examples of how CIP is used in real-world use cases.
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.

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.
Session Highlight: CIP Kernel Team Activities to Accomplish Super Long Term Support
At the end of June, CIP will be participating in many ways at the Linux Foundations’ OpenSource Summit + ELC 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.
Check out talk details below and read on to learn how to register for the event.
CIP (Civil Infrastructure Platform) project aims to support industrial-grade systems in secure and reliable manners. CIP kernel team was launched in 2016 under CIP to provide and maintain Linux kernel for 10+ years, because life cycles of such industrial-grade systems are very long by their nature.
By steadily releasing SLTS (super long-term support) kernel based on LTS4.4 and LTS4.19, the team has continuously improved the release processes and tools to facilitate the team activities. The team works with LTS and other open source projects to share its findings and contribute outputs. Also, test automation has been strengthened. During the long support period of 10+ years, a large number of minor releases are planned, so the cost reduction effect by test automation will be enormous. Open source tools like “cip-kernel-sec” and “classify-failed-patches” were introduced to track the status of CVEs and to identify patches needed to apply to stable kernel, respectively.
This presentation updates CIP kernel team activities, by featuring collaborative works with LTS , the status of test automation using KernelCI and LAVA, and experiences of using the open source tools.
On June 29- July 2 the Linux Foundation is hosting Open Source Summit North America. Open Source Summit is a virtual event that connects the open source ecosystem under one roof. It’s a unique environment for cross-collaboration between developers, sysadmins, devops, architects and others who are driving technology forward. bringing together.
CIP will be participating in many ways at the event including having a virtual booth, several talks by CIP reps as well as hosting the CIP Mini-Summit.
Find details below on two talks given by Wolfgang Mauerer with Technical University of Applied Sciences Regensburg / Siemens AG.
Well-known, large communities and open source projects like the Linux kernel are an often pursued goal of scientific analysis, and questions of interest cover a broad range — core OS design, collaborative software engineering, software architectural questions and community health, to just name a few. However, many research questions are biased towards what can be nicely published, and not on the most pressing problems of projects.
This leads to a gap between what OSS communities need to know, and the insights science can provide. In this (likely opinionated) talk, we discuss this gap from two often opposite sides: As a researcher, the author has never understood why industrial belief in software engineering research seems to often stop at using design patterns, and why industry does not try to benefit more from scientific insight. As an industrial practitioner, the author has never understood why academia would need to tell industrial engineers that have participated in OSS projects for years what they have done, post facto, and why research does not listen more closely to what industry is interested in, and needs to know. We suggest some possibilities to shrink the gap.
Embedded Linux is a standard core component of systems deployed in challenging and critical scenarios. Machine learning and statistical techniques are increasingly used to ascertain or even predict various quality properties — the number of open issues to judge reliability or maximum latencies for real-time systems –, or to improve development and maintenance processes: Techniques to automatically select patches for back-porting or to identify security critical fixes have recently been suggested.
While machine learning undoubtedly has its advantages, it is by no means a panacea for solving all engineering issues that have been around for decades, and issues like lack of explainability or over-confident trust in results often cause unease. But it is also unwise to dismiss them just because they differ from traditional engineering approaches.
In this talk, we survey recent uses of ML techniques in OSS systems development and maintenance, address their benefits and disadvantages, and give recommendations on how especially industrial system integrators and solution providers can enjoy the benefits of new ML-based engineering methods without suffering from new problems.
This October, the Civil Infrastructure Platform will be hosting a half-day Mini-Summit, colocated with the Linux Foundation’s Open Source Summit Europe (OSSEU), taking place in Lyon, France.
The CIP Mini-Summit is a half-day, single-track event covering Linux-based industrial open source systems. The event takes place on October 31st from 8:00 – 13:00 at the Lyon Convention Centre.
With this event, CIP hopes to gather all interested in open source and provide technical details and in-depth insights that will further develop the industrial-grade CIP base layer which is built on the work of established and stable work from the likes of Debian, Yocto, RT Linux. This event is an opportunity to meet and collaborate face to face while advancing CIP’s goal of establishing an open-source “base layer” of industrial-grade software to enable the use and implementation in infrastructure projects of software building blocks that meet the safety, reliability and other requirements of industrial and civil infrastructure. Use cases for this base layer include power plants, radar systems, traffic lights, dams, weather systems and more.
The day will be jam-packed with topics, including:
The State of Civil Infrastructure Platform
CIP SLTS kernel development (e.g. Patch management for collaboration with stable kernel team)
Security in industrial systems and its future
Safe software updates for industrial IoT devices
Use cases of the CIP open source base layer
CIP testing activities will be presented at the Automated Testing Summit, which CIP is a proud sponsor of.
To attend, guests attending OSS EU can register here for a nominal fee of $10 USD.
In addition to The CIP Mini-Summit, CIP is also sponsoring Embedded Linux Conference (ELC-E) as a Gold Sponsor and will be exhibiting on the showroom floor. Stay tuned for details about hands-on demos we’ll be displaying on site!
Embedded Linux Conference Europe takes place from Mon, Oct 28, 2019 – Wed, Oct 30, 2019 is the leading conference for developers, architects, and other technologists – as well as open source community and industry leaders – to collaborate, share information, learn about the latest technologies and gain a competitive advantage by using innovative open solutions.
