The Linux Kernel Runtime Guard (LKRG) is a out-of-tree loadable kernel module that attempts to detect and report violations of the kernel's internal invariants, such as might be caused by an in-progress security exploit or a rootkit. LKRG has been experimental since its initial release in 2018. In September 2025, the project announced the 1.0 version. With the promises of stability that version brings, users might want more information to decide whether to include it in their kernel.

ReactOS, an open-source project to develop an operating system that is compatible with Microsoft Windows NT applications and drivers, is celebrating 30 years since the first commit to its source tree. In that time there have been more than 88,000 commits from 301 contributors, for a total of 14,929,578 lines of code. There is, of course, much left to do.
It's been such a long journey that many of our contributors today, including myself, were not alive during this event. Yet our mission to deliver "your favorite Windows apps and drivers in an open-source environment you can trust" continues to bring people together. [...]
We're continuing to move ReactOS forward. Behind the scenes there are several out-of-tree projects in development. Some of these exciting projects include a new build environment for developers (RosBE), a new NTFS driver, a new ATA driver, multi-processor (SMP) support, support for class 3 UEFI systems, kernel and usermode address space layout randomization (ASLR), and support for modern GPU drivers built on WDDM.

As part of the process of writing man pages for the "new" mount API, which has been available in the kernel since 2019, Aleksa Sarai encountered a number of places where the fsconfig() system call—for configuring filesystems before mounting—needs to be cleaned up. In the 2025 Linux Plumbers Conference (LPC) session that he led, Sarai wanted to discuss some of the problems he found, including at least one with security implications. The idea of the session was for him to describe the various bugs and ambiguities that he had found, but he also wanted attendees to raise other problems they had with the system call.
