The
6.9-rc6 kernel prepatch is out for
testing.
Things continue to look pretty normal, and nothing here really
stands out. The biggest single change that stands out in the
diffstat is literally a documentation update, everything else looks
pretty small and spread out.

The
6.8.8,
6.6.29,
6.1.88, and
5.15.157
stable kernels have been released; each contains another set of important
fixes.

Video playback is undeniably one of the most important features in modern
consumer devices. Yet, surprisingly, users are by and large unaware of the
intricate engineering involved in the compression and decompression of
video data, with codecs being left to find a delicate balance between image
quality, bandwidth, and power consumption. In response to constant
performance pressure, video codecs have become complex and hardware
implementations are now common, but programming these devices is becoming
increasingly difficult and fraught with opportunities for exploitation. I
hope to convey how Rust can help fix this problem.

At the CPU level, a memory model describes, among other things, the amount
of freedom the processor has to reorder memory operations. If low-level
code does not take the memory model into account, unpleasant surprises are
likely to follow. Naturally, different CPUs offer different memory models,
complicating the portability of certain types of concurrent software. To
make life easier, some Arm CPUs offer the ability to emulate the x86 memory
model, but efforts to make that feature available in the kernel are running
into opposition.

Security updates have been issued by Debian (knot-resolver, pdns-recursor, and putty), Fedora (xen), Mageia (editorconfig-core-c, glibc, mbedtls, webkit2, and wireshark), Oracle (buildah), Red Hat (buildah and yajl), Slackware (libarchive), SUSE (dcmtk, openCryptoki, php7, php74, php8, python-gunicorn, python-idna, qemu, and thunderbird), and Ubuntu (cryptojs, freerdp2, nghttp2, and zabbix).

On April 11, Brandt Bucher posted
PEP 744 ("JIT Compilation"),
which summarizes the current state of Python's new
copy-and-patch just-in-time (JIT) compiler. The JIT is currently
experimental, but the PEP proposes some criteria for the circumstances under which it
should become a non-experimental part of Python.
The discussion of the PEP hasn't
reached a conclusion, but
several members of the community have already raised questions
about how the JIT would fit into future iterations of the Python language.

Version 24.04 LTS of the Ubuntu distribution is out.
This release continues Ubuntu's proud tradition of integrating the
latest and greatest open source technologies into a high-quality,
easy-to-use Linux distribution. The team has been hard at work
through this cycle, together with the community and our partners,
to introduce new features and fix bugs.
The list of changes and enhancements is long; click below for some details.
More information can be found in the
release notes; see also this
page for a summary of security-related changes.

Linux, famously, appears in a wide range of systems. While servers and
large data centers get a lot of the attention, and this year will always be
the year of the Linux desktop, there is also a great deal of Linux to be
found in realtime and embedded applications. Two talks held in the
realtime and embedded tracks of the 2024
Open
Source Summit North America provided listeners with an update on how
Linux is doing in those areas. Work on realtime Linux appears to be nearing
completion, while the embedded community is still pushing forward at full
speed.

BleepingComputer
reported on April 20 that some malware was being distributed via GitHub.
Uploading files as part of a comment gives them a URL that appears to be
associated with a repository, even if the comment is never posted.
A GitHub flaw, or possibly a design decision, is being abused by threat actors
to distribute malware using URLs associated with Microsoft repositories, making
the files appear trustworthy.
While most of the malware activity has been based around the Microsoft GitHub
URLs, this "flaw" could be abused with any public repository on GitHub, allowing
threat actors to create very convincing lures.

On April 23, Mozilla
announced that Firefox's crash reporter has been rewritten in Rust, allowing the
project to address a backlog of issues.
Even though it is important to properly handle main process crashes, the crash
reporter hasn't received significant development in a while (aside from
development to ensure that crash reports and telemetry continue to reliably be
delivered)! It has long been stuck in a local maximum of "good enough" and
"scary to maintain": it features 3 individual GUI implementations (for Windows,
GTK+ for Linux, and macOS), glue code abstracting a few things (mostly in C++,
and Objective-C for macOS), a binary blob produced by obsoleted Apple
development tools, and no test suite. Because of this, there is a backlog of
features and improvements which haven't been acted on.

Version 9.0 of
the QEMU emulator has been released. "This release contains 2700+
commits from 220 authors." The list of improvements is long; see the
announcement and
the
changelog for details.

For several years, contributors to the Rust project have
been working to improve support for asynchronous
code. The benefits of these efforts are not confined to asynchronous code,
however. Members of the Rust community have been working toward adding explicit
existential types to Rust since 2017. Existential types are not a common feature
of programming languages (something
the RFC acknowledges), so the motivation for their inclusion might be somewhat
obscure.

Security updates have been issued by Fedora (abseil-cpp, chromium, filezilla, libfilezilla, and xorg-x11-server-Xwayland), Oracle (firefox, gnutls, golang, java-1.8.0-openjdk, java-11-openjdk, java-17-openjdk, java-21-openjdk, kernel, libreswan, mod_http2, owO: thunderbird, and thunderbird), Red Hat (container-tools:rhel8, gnutls, grub2, kernel, kernel-rt, less, linux-firmware, opencryptoki, pcs, postgresql-jdbc, and thunderbird), Slackware (ruby), SUSE (kubernetes1.23, kubernetes1.24, and opensc), and Ubuntu (firefox, linux-azure, linux-lowlatency, linux-nvidia, and ruby-sanitize).

The long-running effort to complete the work on stacking (or composing) the
Linux security modules (LSMs) recently encountered a barrier—in the form of
a "suggestion" to discontinue it from Linus Torvalds. His complaint
revolved around the indirect function calls that are used to implement
LSMs, but he also did not think much of the effort to switch away from
those calls. While it does not appear that a major course-change is in store
for LSMs, it is clear that Torvalds is not happy with the direction of that
subsystem.

The Rust programming language, it is hoped, will bring a new level of
safety to the Linux kernel. At the moment, though, there are still a
number of impediments to getting useful Rust code into the kernel. In the
Embedded Open Source Summit track of the
Open
Source Summit North America, Fabien Parent provided an overview of his
work aimed at improving the infrastructure needed to write the device
drivers needed by embedded systems in Rust; there is still some work to be
done.

Security updates have been issued by Debian (glibc and samba), Fedora (chromium, cjson, mingw-python-idna, and pgadmin4), Mageia (kernel, kmod-xtables-addons, kmod-virtualbox, kernel-linus, and perl-Clipboard), Red Hat (go-toolset:rhel8, golang, java-11-openjdk, kpatch-patch, and shim), Slackware (freerdp), SUSE (apache-commons-configuration, glibc, jasper, polkit, and qemu), and Ubuntu (google-guest-agent, google-osconfig-agent, linux-lowlatency-hwe-6.5, pillow, and squid).

The Open Home Foundation has
announced
its existence as a home and support resource for free home-automation
projects.
We created the Open Home Foundation to fight for the fundamental
principles of privacy, choice, and sustainability for smart
homes. And every person who lives in one.
Ahead of today, we've transferred over 240 projects, standards,
drivers, and libraries—Home Assistant, ESPHome, Zigpy, Piper,
Improv Wi-Fi, Wyoming, and so many more—to the Open Home
Foundation. This is all about looking into the future. We've done
this to create a bulwark against surveillance capitalism, the risk
of buyout, and open-source projects becoming abandonware. To an
extent, this protection extends even against our future selves—so
that smart home users can continue to benefit for years, if not
decades. No matter what comes.
