The 7.3-rc6 kernel prepatch is out for
testing. Linus said:

Next week might look a bit different: we’ve got the annual
maintainer summit and the Linux plumbers conference going on , so
I’ll be on the road, as will a number of other maintainers. That
may or may not end up changing the stats for -rc7. But it’s
unlikely to affect the release schedule, although the fact that I
have my yearly family vacation the week after that might make the
next merge window a bit wonky.

By now it is no secret that large language models (LLMs) have made it easy
for people to identify security bugs, and that has resulted in a flood of
bug reports to almost every free-software project, including the kernel.
At the 2026 edition of Kernel
Recipes, Greg Kroah-Hartman took the stage to talk about how the
kernel’s security team is handling this deluge. His core message was
“don’t panic“.

The 2026 Python Language Summit was held on July 14 in Kraków, Poland;
there is now a
series of reports available on the topics that were discussed there.
They include the memory buffer protocol, garbage collection, free-threaded
Python, and “Spicycrab”.

The election for members of the Linux Foundation Technical Advisory Board
will be held electronically after the close of the upcoming Linux Plumbers Conference. The call for
candidates is is open, with a nomination deadline of October 7.
There are five seats to fill this time, including the one vacated by the
unfortunate passing of Dan Williams.

Serving on the TAB is a good way to help the kernel-development community.
Please see this article from last year for
an overview of what the TAB does and why membership is rewarding, then
consider putting in your nomination.

Andres Freund has a few claims to fame, but
chief among them is his many years of work to improve the performance of
the PostgreSQL relational database
management system. That work requires working with — or around — many
Linux kernel features and behaviors. He put in an appearance at the 2026
edition of Kernel Recipes
to talk about his experience working with the kernel project, how the
kernel could better support applications like PostgreSQL, and some
interesting developments in the PostgreSQL world.

As a professor of biomedical engineering, Martin Uecker perhaps does not
fit the profile of a typical presenter at Kernel Recipes. He is,
however, a longtime Linux user, and works on free software for controlling
magnetic resonance imaging (MRI) scanners. He was at the conference to
talk about the C programming language, the specific problem of undefined
behavior in C, and whether it can eventually be made into a memory-safe
language.

The 7.3-rc5 kernel prepatch is out for
testing. Linus said: “I don’t think there’s any real pattern to it
other than ‘big’. But nothing looks particularly alarming, I think that
despite the diffstat it’s just the same old, same old.“

The Git source-code management system is
at the core of development processes worldwide, so changes, especially
incompatible changes, are of great interest to the developers involved.
The Git 2.56 release, which can be expected around the end of September, is
currently available in release-candidate form. It
is not the most earth-shaking of releases, but the one that follows, which
might be the long-awaited Git 3.0, may well be.

Version 5.6 of the Systemtap tracing tool has been released.

BPF LSM hooks and XDP packet-processing probes for the –bpf
runtime, BTF-based kernel.tracepoint probes, statement execution
tracing, a new @enumname() operator, richer runtime error context,
dyninst hardware watchpoints, modern systemd service templates, and
broad Linux 7.2 runtime/tapset compatibility work. Multithreaded
speedups throughout.

The io_uring
subsystem is all about asynchronous execution; applications count on it
to not block — unless explicitly requested to. Within io_uring, maintaining
the “never blocks” guarantee has sometimes been a challenge, given that
many paths in the kernel were never designed for asynchronous execution.
This problem has been worked around, but at a significant cost to
performance. Now, io_uring maintainer Jens Axboe has posted an RFC patch set
with a somewhat radical (and potentially scary) solution to the problem.

The Register looks
forward to the upcoming Fedora 45 release.

The biggest surprise is that Linux’s legacy in-kernel console – the
text-mode interface normally hidden beneath the GUI – has been
replaced with a software-controlled alternative.
The replacement is kmscon, a
userspace terminal emulator that has been in development for more
than a decade.
