24 May 2021: 4 concrete ways to support seL4 now

RISC-V logo

It has been heart-warming to see the response of the seL4 community to the news of the dismantlement of the Trustworthy Systems group (TS), creator of seL4.

The seL4 Foundation, as well as its members and ecosystem, want to reinforce their commitment to the success and support of seL4. The TS team will be rebuilding at UNSW and a number of Foundation-endorsed seL4 services providers as well as the newly created Proofcraft verification company are dedicated to support seL4 in the future.

With this recent news, it’s never been more important to work together as a community to support seL4 and the transition of the support and development to the Foundation and its members. People have been asking how to help. Offers of support keep coming. We are looking at various options for sustainable support, with a priority of keeping the team together. There are options on the table that we are exploring that may allow us to do that. Please help us with that, the existing TS team is the best base for stable seL4 support.

In the meantime, here are 4 concrete things that can be done now. Spread the word to people who care about seL4’s future, and contact us if you want to discuss.

  1. donations and crowdfunding, in particular towards the “continuity project".
    seL4 crowdfunding page
    The crowd-funding platform works for large and small financial contributions, and contributions can be dedicated to specific topics. Fans are always welcome to contribute and show the continued support to seL4 :), but if you know of companies that would like to show financial support without a longer-term commitment, this is a quick and easy mechanism to do so.
    We have set up a dedicated “continuity project” to raise funds specifically targeted to the transition of the infrastructure (testing, boards etc) and the immediate support needs (maintenance of all configurations, libraries, releases etc) to the Foundation. All donors of $1,000 and above will be listed on the page above.
  2. get more members signed up to the Foundation.
    A push to get more organisations joining in the coming weeks will be a clear message of the strong support to seL4 and will provide the necessary funds funds to transition more support to the Foundation. Longer term, membership helps deliver on the Foundation’s vision to increase usability, exposure, support, education, participation, and verification of seL4. Join or help spreading the word to join to your partners and customers.
  3. in-kind offer of expertise.
    The number of seL4 experts is growing. Active participation and especially support for new users and beginners on Discourse ( and the mailing list will help keep the community active. Likewise contributions to reviews and discussion on GitHub on pull requests and issues will help to keep things moving. The focus has shifted away from just D61 contributions in the past year already, now is the time to keep the momentum up. The TS team and people in the technical steering committee are working on moving testing and verification infrastructure to UNSW. This will include opening up the infrastructure such that members can contribute hardware tests. We will send more information about this in the next few weeks. Please contact Gerwin as the TSC chair if you are interested in this or have additional ideas how to help.
    We were gearing up for the next seL4 release. This might be slightly delayed by the infrastructure move, but if everything comes together as planned the release will go ahead.
  4. jobs in the seL4 ecosystem.
    While some expertise is needed to be kept within the Foundation, it is also important to keep it within the community. We have just set up a page for members to post jobs related to seL4. This will help match seL4 experts to organisations willing to build upon, develop or support seL4. Contact to post on that page.
23 May 2021: New "Jobs" page on the seL4 Foundation website

RISC-V logo The community has expressed a need to more easily find seL4 experts to hire. The Foundations has created a "Jobs in seL4 ecosystem" page where members can post offers for positions with seL4 expertise.

5 May 2021: RISC-V International and seL4 Foundation Announce New Security Milestone

RISC-V logo Today, the seL4 Foundation and RISC-V International announced that the verified seL4 microkernel on the RV64 architecture has been proved down to the executable code by CSIRO’s Data61, thanks to funding provided by HENSOLDT Cyber GmbH. This guarantees that the seL4 microkernel on RV64 will operate to specification even when built with an untrusted C compiler, GCC.

Within and across open collaboration communities it is essential to work together on areas of mutual interest. RISC-V and seL4 are pleased to announce their progress and their alliances as they join forces to enable stronger overall security, combining security-oriented architecture and operating system design.

“We are excited to be one of the first architectures with secure operating system kernels with such a strong formal verification story,” said Mark Himelstein, CTO of RISC-V International. “RISC-V is continuing to increase the security features that encompass the ISA and the secure seL4 kernel is a natural complement.”

“This is another milestone for seL4, which continues to define the state of the art in OS security,” added Prof Gernot Heiser, Chairman of the seL4 Foundation. “Stronger aligning the two open ecosystems makes a lot of sense.”

“The verified seL4 microkernel forms the core of TRENTOS, our secure operating system for our MiG-V chip, a RISC-V processor with supply chain security”, said Sascha Kegreiß”, CTO of HENSOLDT Cyber GmbH. “This unique combination of hardware and software security can protect critical assets from advanced persistent cyber threats.”

”Translation validation ties all of our verification efforts together,” said Dr Zoltan Kocsis, CSIRO Verification Engineer. “Bringing translation validation to a modern, 64-bit processor presented significant scalability challenges but, in the end, we were able to overcome them.”

For more details on binary verification of seL4 on RISC-V see Gernot's blog: seL4 on RISC-V Verified to Binary Code (and seL4 and RISC-V Foundations form an alliance).
