GyroidOS virtualization solution aims to secure embedded devices, ease cybersecurity certification

GyroidOS

Maintained by Fraunhofer AISEC, GyroidOS is an open-source, multi-arch OS-level virtualization solution designed for embedded devices with hardware security features, and aiming to support security certification processes such as Common Criteria (ISO/IEC 15408), DIN SPEC 27070 – IDS Trust Security profile, and IEC-62443 cybersecurity standards. The virtualization layer is based on Linux-specific features like namespaces, cgroups, and capabilities to provide isolation of different guest operating system stacks on top of a single, shared Linux kernel. It offers a much smaller footprint and additional separation of privileged instances compared to other container solutions, such as Docker. GyroidOS security features Container isolation based on a modularized OS-level virtualization layer Secure boot (e.g., UEFI on x86) Kernel module signing Signed GuestOSes (containers) Measured boot and remote attestation Full disk encryption coupled to TPM and secure boot Restriction of superuser in containers with Linux capabilities Fine-grained device access with device cgroups whitelists Secure Element […]

Linux 6.19 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.19

Linus Torvalds has just released Linux 6.19 on the Linux Kernel Mailing List (LKML): No big surprises anywhere last week, so 6.19 is out as expected – just as the US prepares to come to a complete standstill later today watching the latest batch of televised commercials. The betting man would expect them all to be AI-generated, but maybe some enterprising company decides to buck the trend? Doubtful, but there’s always a slight chance. But for anybody outside the US, maybe taking the newest kernel out for a spin instead is an option? I have more than three dozen pull requests for when the merge window opens tomorrow – thank you to all the early maintainers. And as people have mostly figured out, I’m getting to the point where I’m being confused by large numbers (almost running out of fingers and toes again), so the next kernel is going to […]

Linux 6.11 Release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.11 release

Linux 6.11 is out with Linus Torvalds’ announcement on the Linux kernel mailing list (LKML): I’m once again on the road and not in my normal timezone, but it’s Sunday afternoon here in Vienna, and 6.11 is out. The last week was actually pretty quiet and calm, which is nice to see. The shortlog is below for anybody who wants to look at the details, but it really isn’t very many patches, and the patches are all pretty small. Nothing in particular stands out – the biggest patch in here is for Hyper-V Confidential Computing documentation. Anyway, with this, the merge window will obviously open tomorrow, and I already have 40+ pull requests pending. That said, exactly _because_ I’m on the road, it will probably be a fairly slow start to the merge window, since not only am I on my laptop, there’s OSS Europe starting tomorrow and then the […]

Linux 6.10 Release Changelog

Linux Torvalds has announced the release of Linux 6.10 on LKML: So the final week was perhaps not quote as quiet as the preceding ones, which I don’t love – but it also wasn’t noisy enough to warrant an extra rc. And much of the noise this last week was bcachefs again (with netfs a close second), so it was all pretty compartmentalized. In fact, about a third of the patch for the last week was filesystem-related (there were also some btrfs latency fixes and other noise), which is unusual, but none of it looks particularly scary. Another third was drivers, and the rest is “random”. Anyway, this obviously means that the merge window for 6.11 opens up tomorrow. Let’s see how that goes, with much of Europe probably making ready for summer vacation. And the shortlog below is – as always – just the last week, not some kind […]

Linux 6.8 release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux 6.8 release

Linus Torvalds has just announced the release of Linux 6.8 on the Linux kernel mailing list: So it took a bit longer for the commit counts to come down this release than I tend to prefer, but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems. And the last two weeks have been pretty quiet, so I feel there’s no real reason to delay 6.8. We always have some straggling work, and we’ll end up having some of it pushed to stable rather than hold up the new code. Nothing worrisome enough to keep the regular release schedule from happening. As usual, the shortlog below is just for the last week since rc7, the overall changes in 6.8 are obviously much much bigger. This is not the historically big release that 6.7 was – we seem to […]

Microchip announces the PolarFire SoC Discovery Kit, a low-cost devkit for Linux and real-time applications

Microchip PolarFire SoC Discovery Kit

The SoC Discovery Kit is the latest addition to Microchip’s list of development kits for the PolarFire series. The series is the first SoC FPGA family powered by a deterministic, coherent RISC-V CPU cluster. They provide low power consumption, thermal efficiency, and defense-grade security for smart, networked systems. They also support a deterministic L2 memory system for Linux and real-time applications. Microchip launched the Icicle Kit for the PolarFire SoC in 2020 and it was followed by the Video and Imaging Kit which was intended for mid-bandwidth imaging and video applications. Now, Microchip has announced the Discovery Kit which is billed as a low-cost alternative to the Icicle. The Discovery Kit retains the full range of features needed for testing concepts quickly, developing firmware applications, and programming/debugging user code. According to Microchip, the kit will bring “a low-cost RISC-V and FPGA development for learning and rapid innovation” to new and […]
