Today, @_minipli has submitted patches for the NVIDIA open gpu kernel modules that implement full Kbuild support, paving the way for CFI, KASAN/UBSAN, and our many compiler plugins. Running AI workloads with NVIDIA GPUs no longer means weakening kernel security. Links below 👇

Here is our report for the first month of 2026, with an interesting little dive into a name resolution problem we fixed this month :) rust-gcc.github.io/2026/02/10/202…

Our 6.18 #grsecurity LTS release, to be supported through at least the end of 2028, is now available!

Hi everyone! Here is our last report for the year 2025 and a small update from the team. Thanks again for a very fun 2025 and we look forward to do it all over again :) rust-gcc.github.io/2026/01/08/202…

6.18 has been selected as the next #grsecurity stable kernel version, to be supported through the end of 2028, one year longer than the upstream LTS EOL date of Dec 2027.

rust-gcc.github.io/2025/09/09/202… Short report for the month of August and a recap of the work done this summer - we're full steam ahead working on compiling core and the kernel's crate!

Monthly report for July 2025: rust-gcc.github.io/2025/08/05/202…

Our report for the month of June: rust-gcc.github.io/2025/07/17/202… Still making good progress and progressing fast towards testing the kernel's alloc crate

New report for the month of May: rust-gcc.github.io/2025/06/04/202… We are making good progress on core and plan on begin testing the Rust code in the kernel at the end of the summer!

Monthly report for the month of March: rust-gcc.github.io/2025/04/15/202… Which mentions some of the work done for supporting specialization in `core` :) We've upstreamed 600 commits to GCC this month and will continue to do so until 15.1 releases!

Here is our monthly report for February, with more explanations of the features we are currently working on. See you all in Paris tomorrow for Rust In Paris 2025! rust-gcc.github.io/2025/03/10/202…

First monthly report of the year with some code snippets of our two main targets (Rust-for-Linux and Rust's core crate) to show the importance of the milestones we are working on: rust-gcc.github.io/2025/02/06/202…

Here is our monthly report for the month of December 2024, which includes a small technical dive into the handling of auto traits and the desugaring of for-loops: rust-gcc.github.io/2025/01/07/202…

Slides for @wipawel's H2HC presentation this month on the TLB are now available on grsecurity.net/papers If you've never heard of "paging-structure caches" before, check it out!

New monthly report for November is out, with a slight dive into type-system fun :) and most importantly contributions from the rustc_codegen_gcc folks! rust-gcc.github.io/2024/12/02/202…

Performance isn't the enemy of security: we care about both. Today's patches finish off a set of security/performance improvements to eBPF. Below we show a ~30x speedup vs vanilla in running the eBPF selftests with every single #grsecurity option enabled!

The first ever end-to-end cross-process Spectre exploit? I worked on this during an internship with @grsecurity! An in-depth write-up here: grsecurity.net/cross_process_…

We have written a short technical dive into how we currently reuse Rust components within gccrs, a compiler written in C++, and how we will continue doing so in the future, eventually compiling them using our own compiler. rust-gcc.github.io/2024/09/20/reu…
