Kernel development and machine learning seem like vastly different areas of
endeavor; there are not, yet, stories circulating about the vibe-coding of
new memory-management algorithms. There may well be places where machine
learning (and large language models — LLMs — in particular) prove to be
helpful on the edges of the kernel project, though. At the 2025
North-American edition of the Open Source Summit, Sasha Levin presented
some of the work he has done putting LLMs to work to make the kernel better

It took time and the writing of over 60 articles, but LWN’s coverage from
the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit is now complete. We have also made
an EPUB book (13MB) containing
the full set of coverage available to all readers. This coverage
constitutes the definitive guide to the challenges that these core-kernel
communities are facing and their development plans for the coming year.
Documenting an event of this intensity at such a detailed level is not a
small undertaking. We are grateful to the Linux Foundation for funding our
travel to our event and, especially, to LWN’s subscribers for making the
whole thing possible. If you appreciate this type of coverage and have not
yet subscribed, please sign up today to help make
more of it possible.

Version
140.0 of the Firefox browser has been released. Changes include more
control over vertical tabs, a dialog to add custom search engines,
improvements to translation performance, and more.

Working on the kernel can be a challenging task but, for many,
configuring a kernel build can be the largest obstacle to getting
started. The kernel has thousands of configuration options; many of those,
if set incorrectly, will result in a kernel that does not work on the
target system. The key to helping users with complex configuration
problems is to provide reasonable defaults but, in the kernel community,
there is currently little consensus around what those defaults should be.

Linus has released 6.16-rc3 for testing.
“So rc2 was smaller than usual, but rc3 seems to be right in the usual
“
ballpark for this time, so everything looks entirely normal.

Born from research at the Southern University of Science and
Technology (SUSTech) in Shenzen, China, Asterinas is a new
Linux-ABI-compatible kernel project written in Rust, based on what the
authors call a “framekernel architecture”. The project overlaps somewhat
with the goals of the Rust for Linux
project, but approaches the problem space from a different direction by
trying to get the best from both monolithic and microkernel designs.

The POSIX
realtime model, which is implemented in the Linux kernel, can ensure
that a realtime process obtains the CPU time it needs to get its job done.
It can be less effective, though, when there are multiple realtime
processes competing for the available CPU resources. The hierarchical
constant bandwidth server patch series, posted by Yuri Andriaccio with
work by Luca Abeni, Alessio Balsini, and Andrea Parri, is a modification to
the Linux scheduler intended to make it possible to configure systems with
multiple realtime tasks in a deterministic and correct manner.

The open-source mobile app Organic
Maps is used by millions of people on both the Android and iOS
platforms. In addition to featuring offline maps (generated from OpenStreetMap cartography) and
turn-by-turn navigation, it also promises its users greater privacy
than proprietary options. However, controversial decisions taken by the
project’s leaders, feelings of disenfranchisement among contributors, and
even accusations of embezzlement have precipitated a divide in the
community, leading to a new fork called CoMaps.

The Python Software Foundation blog is carrying a
set of detailed summaries from the 2025 Python Language Summit:
The Python Language Summit 2025 occurred on May 14th in Pittsburgh,
Pennsylvania. Core developers and special guests from around the
world gathered in one room for an entire day of presentations and
discussions about the future of the Python programming language.
Topics covered include making breaking changes less painful, free-threaded
Python, interaction with Rust, and challenges faced by the Steering
Council.

The “Local Mess” GitHub
repository is dedicated to the disclosure of an Android tracking
exploit used by (at least) Meta and Yandex.
While there are subtle differences in the way Meta and Yandex
bridge web and mobile contexts and identifiers, both of them
essentially misuse the unvetted access to localhost sockets. The
Android OS allows any installed app with the INTERNET permission to
open a listening socket on the loopback interface
(127.0.0.1). Browsers running on the same device also access this
interface without user consent or platform mediation. This allows
JavaScript embedded on web pages to communicate with native Android
apps and share identifiers and browsing habits, bridging ephemeral
web identifiers to long-lived mobile app IDs using standard Web
APIs.
This backdoor, the use of which has evidently stopped since its disclosure,
allow tracking of users across sites regardless of cookie policies or use of
incognito browser modes.

The Linux kernel famously scales from the smallest of systems to massive
servers with thousands of CPUs. It was not always that way, though; the
initial version of the kernel could only manage a single processor. That
limitation was lifted, obviously, but single-processor machines have always
been treated specially in the scheduler. That longstanding situation may
soon come to an end, though, if this patch
series from Ingo Molnar makes it upstream.

The Open Invention Network (OIN) is celebrating
its 20th anniversary.
The central feature of the OIN community is a patent cross-license
that covers core Open Source functionality and expands in parallel
with the growth of Open Source technology. As growth in Open Source
has accelerated, OIN has proactively expanded the scope of the OIN
license’s benefit by including more than 4,500 software components
and platforms in its Linux System definition, which comprises the
list of Open Source code and associated functionality in OIN’s
patent cross-license.
LWN’s first look at OIN was this article by
Pamela Jones in late 2005.

The
6.15.2,
6.14.11, and
6.12.33
stable kernel updates have been released; each contains a relatively small
set of important fixes.
Note that this is the end of the line for the 6.14.x updates; Greg
Kroah-Hartman explains the timing of this move:
If you notice, this has happened a bit more “early” than previous
end-of-life announcements. Normally, after -rc1 is out there is a
TON of stable patches happening due to the changes that come into
the merge-window that were marked for stable backports but didn’t
get into Linus’s release before -final. As some people have
objected to this large influx being added to a stable kernel that
is just about to go end-of-life, let’s try marking this end-of-life
a bit earlier to see how it goes.
