[$] Zero-copy for FUSE

In a combined storage and filesystem session at the 2025 Linux Storage,
Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), Keith Busch led
a discussion about zero-copy operations for the Filesystem
in Userspace
(FUSE) subsystem. The session was proposed
by his colleague, David Wei, who could not make it to the summit, so Busch
filled in, though he noted that “I do not really know FUSE so
well
“. The idea is to eliminate data copies in the data path to and
from the FUSE server in user space.

[$] Open source and the Cyber Resilience Act

The European Union’s

Cyber Resilience Act
(CRA) has caused a stir in the
software-development world. Thanks to advocacy by the Eclipse Foundation, Open
Source Initiative, Linux Foundation, Mozilla, and others, open-source software
projects generally have minimal requirements under the CRA
— but nothing to do with law is ever quite
so simple. Marta Rybczyńska spoke at Linaro Connect 2025 about the impact of the
CRA on the open-source ecosystem, with an emphasis on the importance of
understanding a project’s role under the CRA. She later participated in a panel
discussion with Joakim Bech, Kate Stewart, and Mike Bursell about how the CRA
would impact embedded open-source development.

Linux 6.15 & Early Linux 6.16 Delivering Some Additional Gains For AMD Strix Halo

As some extra benchmarks to put out today for the Phoronix.com 21st birthday, there is some additional data points to share on AMD Strix Halo when using Linux 6.15 stable and the early development state of Linux 6.16 Git ahead of its v6.16-rc1 tagging this weekend. The Linux kernel performance is moving in the right direction at least with this round of testing using the HP ZBook Ultra G1a with Ryzen AI Max+ PRO SoC…

FreeBSD Developers Deciding What To Do For WiFi With FreeBSD 15: Stable Or Unstable

FreeBSD developers have been working a lot on their wireless/WiFi driver support in recent months as part of their broader initiative for improving their operating system support for laptops. While a lot of progress has been made on seeing more modern WiFi support and recent WiFi chipsets being enabled, it’s still not complete and that puts FreeBSD 15 in a tough position. FreeBSD 15 is set to be released later this year and will likely declare their wireless support as “unstable” to allow time for making future breaking modifications…

[$] Fending off unwanted file descriptors

One of the more obscure features provided by Unix-domain sockets is the
ability to pass a file descriptor from one process to another. This
feature is often used to provide access to a specific file or network
connection to a process running in a relatively unprivileged context. But
what if the recipient doesn’t want a new file descriptor? A feature
added for the 6.16 release makes it possible to refuse that offer.

PanVK Open-Source Vulkan Driver for ARM Mali GPUs Is Now Vulkan 1.2 Conformant

Only six months after reaching Vulkan 1.1 conformance, the PanVK open-source graphics driver for ARM Mali GPUs is now officially conformant with the Vulkan 1.2 specification on Mali-G610 GPUs. With that crossed from the list, Collabora is now working on updating PanVK’s Vulkan specification to Vulkan 1.3 and 1.4.
