Runtime Verification (RV) tool – The Runtime Verification System, merged on Linux 6.0, is a lightweight method that complements classical exhaustive verification techniques (such as model checking and theorem proving) with a more practical approach for complex systems. ![]() The new release also adds FineIBT mitigation feature based on the software kCFI implementation and uses hardware IBT support where present to annotate and track indirect branches using a hash to validate them. ![]() This new method can be enabled with the boot option retbleed=stuff. Linux 6.2 implements a lighter-weight software-only fix for Skylake-based cores where enabling IBRS is a big hammer and causes a significant performance impact. Faster mitigation of the Retbleed speculative execution attack on x86-64 and ARM processors, and FineIBT – The techniques used to mitigate the Retbleed vulnerability had a considerable impact on performance.Some notable changes in Linux 6.2 include: The previous Linux 6.1 was released as an LTS (Long Term Support) kernel with initial support for the Rust programming language, KMSAN kernel memory sanitizer, the Multi-gen LRU (MG-LRU) implementation for better swap file/partition management, and many other changes. Maybe it’s not a sexy LTS release like 6.1 ended up being, but all those regular pedestrian kernels want some test love too. I like how people have started to take the whole “ready for the merge window” to heart.īut in the meantime, please do give 6.2 a testing. Nothing seemed even remotely worth trying to delay things for.Īnd this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. The shortlog is tiny and appended below, you can scroll through it if you’re bored. ![]() Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. So here we are, right on (the extended) schedule, with 6.2 out. Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual:
