[$] Device-initiated I/O

Peer-to-peer DMA (P2PDMA) has been part of
the kernel since the 4.20 release in 2018;
it provides a framework that allows devices to transfer data between themselves
directly, without using system RAM for the transfer. At the 2025 Linux
Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), Stephen
Bates led a combined storage, filesystems, and memory-management session on
device-initiated I/O, which is perhaps what P2PDMA is evolving toward. Two
years ago, he led a session on P2PDMA at the
summit; this year’s session was a brief update on P2PDMA with a look
at where it may be heading.

Strategy 2028 update (Fedora Community Blog)

Outgoing Fedora Project Leader Matthew Miller has posted an update
on Fedora’s high-level plan through 2028:

[Fedora] Council members identified potential Initiatives that we
believe are important to work on next. We came up with a list of
thirteen — which is way more than we can handle at once. We previously
set a limit of four Initiatives at a time. We decided to keep to that
rule, and are planning to launch four initiatives in the next months

The initiatives are: making Fedora releases block on accessibility
issues, experimenting with a “GitOps” workflow for packaging,
migrating from Pagure to Forgejo, and “making sure Fedora
Linux is ready for people who want to work on machine learning and AI
development
“.

[$] Two sessions on faster networking

Cong Wang and Daniel Borkmann each led session at the 2025 Linux Storage,
Filesystem, Memory Management, and BPF Summit about their respective
plans to speed up networking in the Linux kernel. Both sessions described ways
to remove unnecessary operations in the networking stack, but they focused on
different areas. Wang spoke about using BPF to speed up socket operations,
while Borkmann spoke about eliminating the overhead of networking
operations on virtual machines.

[$] The importance of free software to science

Free software plays a critical role in science, both in research and in
disseminating it. Aspects of software freedom are directly relevant to
simulation, analysis, document preparation and preservation, security,
reproducibility, and usability. Free software brings practical and specific
advantages, beyond just its ideological roots, to science, while
proprietary software comes with equally specific risks. As a practicing
scientist, I would like to help others—scientists or not—see the benefits
from free software in science.

TikTok “ClickFix” Videos Are Spreading Malware — And Now Targeting Linux

A new social engineering tactic known as “ClickFix” is gaining momentum on TikTok, where seemingly harmless tech tip videos are being used to lure users into downloading malware. These short clips pretend to offer simple fixes for browser issues or system errors, but in reality, they redirect viewers to download malicious files that install infostealers. Even more concerning is that attackers are now starting to experiment with this technique on Linux systems as well — a development covered in detail here: Hackers now testing ClickFix attacks on Linux systems.

SMT Proves Very Advantageous For AMD Ryzen AI MAX Strix Halo Performance

While Intel opted against implementing Hyper Threading for their latest Arrow Lake and Lunar Lake processors, Simultaneous Multi-Threading (SMT) still proves very effective on the AMD side. Even though the top-end AMD Ryzen AI MAX “Strix Halo” SoCs provide 16 Zen 5 cores, the presence of SMT for 32 threads still proves worthwhile from both a performance and power efficiency perspective. Here is an on/off comparison for SMT with the flagship AMD Ryzen AI MAX+ PRO 395 within the HP ZBook Ultra G1a.
