In the filesystem track at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), Amir Goldstein wanted to resume discussing a feature that he had briefly introduced at the end of a 2023 summit session: filesystem 'write barriers'. The idea is to...

The Linux kernel can be configured so that kernel modules must be signed or otherwise authenticated to be loaded into the kernel. Some BPF developers want that to be an option for BPF programs as well — after all, if those are going to run as part of the kernel, they...
The Userspace I/O (UIO) subsystem was first added to the kernel by Hans J. Koch for the 2.6.32 release in 2007. Its purpose is to facilitate the writing of drivers (mostly) in user space; to that end, it provides access to a number of resources that user-space code normally...

Anton Protopopov kicked off the BPF track on the second day of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit with a discussion about permitting indirect calls in BPF. He also spoke about his continuing work on static keys, a topic which is related...
The Fedora Project's RISC-V special-interest group (SIG) has announced the availability of Fedora Linux 42 images for supported RISC-V boards, as well as QEMU and container images. The SIG is working toward making RISC-V a primary architecture for Fedora, and has made...
The Python Steering Council accepted PEP 750 ('Template Strings') on April 10. LWN covered the discussion around the proposal, including the substantial revisions to the idea that were needed for it to be accepted. Template strings (t-strings) are a new kind of string that...
Ask a Linux enthusiast who created the Linux kernel, and odds are they will have no trouble naming Linus Torvalds—but many would be stumped if asked what the first Linux distribution was, and who created it. Some might guess Slackware, or its predecessor, Softlanding Linux...

The 6.15-rc3 kernel prepatch is out for testing. 'There's absolutely nothing of huge note here as far as I can tell. Just a fair number of small fixes all over the place'.

The New Stack looks at EU OS, an attempt to create a desktop system for the European public sector. EU OS is not a brand-new Linux distribution in the traditional sense. Instead, it is a proof-of-concept built atop Fedora's immutable KDE Plasma spin (Kinoite). EU OS takes...
The final session in the memory-management track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit was a brief, last-minute addition run by Kalesh Singh. The kernel's readahead mechanism is generally good for performance; it ensures that data is...
Adding tracepoints to some kernel subsystems has been controversial—or disallowed—due to concerns about the user-space ABI that they might create. The virtual filesystem (VFS) layer has long been one of the subsystems that has not allowed any tracepoints, but that may be ...

The kernel's memory controller works within the control-group mechanism to enforce memory-usage limits on groups of processes. This component has often had performance problems, so there is continual interest in optimizing it. Shakeel Butt led a session during the...
