Bindgen is a widely used tool that automatically generates Rust bindings from C headers. The Rust-for-Linux project uses it to create some of the bindings between Rust code and the rest of the kernel. John Baublitz presented at Kangrejos about the improvements that he has made to the tool in order to make the generated bindings easier to use, including improved support for macros,...

The Julia project has released version 1.11.0. A separate blog post covers some of the highlights. The release includes a number of helpful features. In previous Julia versions, there was no "programmatic way" of knowing if an unexported name was considered part of the public API or not. Instead, the guideline was basically that if it was not in the manual then it was...

Security updates have been issued by AlmaLinux (firefox, mod_jk, and thunderbird), Debian (apache2 and firefox-esr), Fedora (crosswords, logiops, p7zip, and perl-App-cpanminus), Red Hat (.NET 6.0, firefox, git, kernel, kernel-rt, openssl, and thunderbird), SUSE (buildah, json-lib, kernel, Mesa, mozjs78, pgadmin4, podman, podofo, qatlib, redis7, roundcubemail, rusty_v8, and seamonkey), and Ubuntu (dotnet6, dotnet8, nginx, and ruby-webrick).

In the early days of open source, it was a struggle to get companies to accept the concept and trust its development model. Now, companies have few qualms about using it, but do tend to take open source and those who maintain it for granted. The struggle now is to find ways to compensate producers of the software, sustain the open‑source commons, and avoid...

Alice Ryhl has been working to enable tracepoints — which are widely used throughout the kernel — to be seamlessly placed in Rust code as well. She spoke about her approach at Kangrejos. Her patch set enables efficient use of static tracepoints, but supporting dynamic tracepoints will take some additional effort.

Security updates have been issued by Debian (kernel), Fedora (webkitgtk), Mageia (cups), Oracle (e2fsprogs, kernel, and kernel-container), Red Hat (buildah, container-tools:rhel8, containernetworking-plugins, git-lfs, go-toolset:rhel8, golang, grafana-pcp, podman, and skopeo), SUSE (Mesa, mozjs115, podofo, and redis7), and Ubuntu (cups and cups-filters).

OpenBSD 7.6 has been released. Notable new features include work to improve suspend/resume on modern hardware, support for the arm64 Qualcomm Snapdragon X Elite laptops, as well as many improvements in hardware support and driver bug fixes. With this release all files that existed in the first commit in the OpenBSD source repository have been updated, modified or replaced at some point in time, reaching...

The recent WordPress controversy is not the first time there's been tension between the WordPress community, the interests of Automattic as a business, and Matt Mullenweg's leadership as WordPress's benevolent dictator for life (BDFL). In particular, Mullenweg's focus on pushing WordPress to use a new "editing experience" called Gutenberg caused significant friction—and led to the ClassicPress fork. Users who want to preserve the "classic"...

Version 3.13 of the Python programming language has been released. The "What's New In Python 3.13" page has a summary of all the new features and changes. Highlights of the release include a basic JIT compiler, experimental support for free-threading, and much more. See the changelog for even more details.

The core of the Android operating system, as represented by the Android Open Source Project (AOSP), can only be considered one of the most successful open-source initiatives ever created; its user count is measured in the billions. But few would consider it to be a truly community-oriented project. At the 2024 Linux Plumbers Conference, Chris Simmonds asked why the AOSP community is so hard...

Version 2.47.0 of the Git source-code management system has been released. The changes include a long list of incremental improvements; see the announcement and this GitHub blog post for details.

Version 4.20 of the RPM Package Manager (RPM) has been released. Major changes in this release include a new plugin to prevent filesystem and network access by scriptlets, the BuildSystem directive for declaring the build system to be used by packaged software, and more. LWN covered the development of RPM 4.20 in September.

Security updates have been issued by AlmaLinux (go-toolset:rhel8 and linux-firmware), Arch Linux (oath-toolkit), Debian (e2fsprogs, firefox-esr, libgsf, mediawiki, and oath-toolkit), Fedora (aws, chromium, firefox, p7zip, pgadmin4, python-gcsfs, unbound, webkitgtk, znc, znc-clientbuffer, and znc-push), Mageia (ghostscript and rootcerts nss firefox firefox-l10n), Oracle (kernel, oVirt 4.4 ovirt-engine, and thunderbird), SUSE (chromedriver, chromium, cups-filters, ffmpeg-7, frr, Mesa, openssl-3, openvpn, pcp, and redis), and Ubuntu (firefox and ruby-webrick).

Linus has released 6.12-rc2 for testing. Anyway, this isn't one of the small rc2's. But looking at historical trends, being a bigger rc2 isn't _that_ unusual, and nothing in here looks all that odd. Yes, the diffstat may look a bit unusual, in that we had a global header renaming (asm/unaligned.h -> linux/unaligned.h) and we had a couple of reverts that stand out as...

Akamai released a report pointing out that the recently-reported CUPS vulnerability (original disclosure) could be used to drive distributed denial-of-service (DDoS) attacks as well. Even if an attacker cannot gain remote control over a computer, they can still cause it to fetch a URL of their choice — potentially getting free DDoS amplification. The Akamai Security Intelligence and Response Team (SIRT) found that more...

Rust has a plethora of smart-pointer types, including reference-counted pointers, which have special support in the compiler to make them easier to use. The Rust-for-Linux project would like to reap those same benefits for its smart pointers, which need to be written by hand to conform to the Linux kernel memory model. Xiangfei Ding presented at Kangrejos about the work to enable custom smart...

The 6.11.2, 6.10.13, and 6.6.54 stable kernels have been released. They contain important fixes, and upgrading is, as always, recommended.

The SUSE Security Team Blog has a detailed report on its discovery of a privilege escalation in the oath-toolkit, which provides libraries and utilities for managing one-time password (OTP) authentication. Fellow SUSE engineer Fabian Vogt approached our Security Team about the project's PAM module. A couple of years ago, the module gained a feature which allows to place the OTP state file (called usersfile)...

Security updates have been issued by AlmaLinux (firefox, golang, linux-firmware, and thunderbird), Debian (kernel and zabbix), Fedora (firefox, pgadmin4, and php), Mageia (chromium-browser-stable, cjson, hostapd and wpa_supplicant, and openjpeg2), Oracle (firefox, flatpak, and go-toolset:ol8), Red Hat (cups-filters, firefox, grafana, linux-firmware, python3, python3.11, and python3.9), SUSE (expat, firefox, libpcap, and opensc), and Ubuntu (freeradius, imagemagick, and unzip).

Cameras were never the simplest of devices for Linux to support; they have a wide range of operating parameters and can generate high rates of data. In recent years, though, they have become increasingly complex, stressing the ability of the kernel's media subsystem to manage them. At the 2024 Linux Plumbers Conference, developers from that subsystem and beyond gathered to discuss the state of...

Security updates have been issued by AlmaLinux (cups-filters), Debian (chromium and php8.2), Fedora (firefox), Oracle (cups-filters, flatpak, kernel, krb5, oVirt 4.5 ovirt-engine, and python-urllib3), Red Hat (cups-filters, firefox, go-toolset:rhel8, golang, and thunderbird), SUSE (postgresql16), and Ubuntu (gnome-shell and linux-azure-fde-5.15).

The open-source vector-graphics editor, Inkscape, is expected to release version 1.4 in October. The release represents an evolutionary step for the program, which brings new features, user-interface improvements, new and improved file-format support, and important changes to the code base. The changes in this release should improve the user experience for both casual and professional designers, and make Inkscape more compatible with proprietary vector-graphics software,...

BPF Type Format (BTF), BPF's debugging information format, has undergone rapid evolution to match the evolving needs of BPF programs. José Marchesi spoke at Kangrejos about some of that work — and how it could impact Rust, specifically. He discussed debug information, kernel-specific relocations, and the planned changes to kernel stack unwinding. Each of these will require some amount of work to fully support...
