OpenSUSE considers dropping reiserfs

월, 2022/08/08 - 2:53오전
As Jeff Mahoney notes in this message to the openSUSE factory list, the reiserfs filesystem has been unmaintained for years and lacks many of the features that users have come to expect. He has thus proposed removing reiserfs from openSUSE Tumbleweed immediately.

I recognize that there may be people out there with disks containing reiserfs file systems. If these are in active use, I would seriously encourage migrating to something actively maintained.

[$] 6.0 Merge window, part 1

금, 2022/08/05 - 11:01오후
The merge window for the kernel that will probably be called "6.0" has gotten off to a strong start, with 6,820 non-merge changesets pulled into the mainline repository in the first few days. The work pulled so far makes changes all over the kernel tree; read on for a summary of what has happened in the first half of this merge window.

GitLab plans to delete dormant projects in free accounts (Register)

금, 2022/08/05 - 5:28오전
The Register reports that GitLab is planning to start deleting repositories belonging to free accounts if they have been inactive for at least a year.

GitLab is aware of the potential for angry opposition to the plan, and will therefore give users weeks or months of warning before deleting their work. A single comment, commit, or new issue posted to a project during a 12-month period will be sufficient to keep the project alive.

[$] A security-module hook for user-namespace creation

목, 2022/08/04 - 11:10오후
The Linux Security Module (LSM) subsystem works by way of an extensive set of hooks placed strategically throughout the kernel. Any specific security module can attach to the hooks for the behavior it intends to govern and be consulted whenever a decision needs to be made. The placement of LSM hooks often comes with a bit of controversy; developers have been known to object to the performance cost of hooks in hot code paths, and sometimes there are misunderstandings over how integration with LSMs should be handled. The disagreement over a security hook for the creation of user namespaces, though, is based on a different sort of concern.

Mena Quintero: Paying technical debt in our accessibility infrastructure

목, 2022/08/04 - 10:47오후
On his blog, Federico Mena Quintero posted a transcript of his recent talk at GUADEC 2022 on the technical debt in the GNOME accessibility infrastructure—and what he has been doing to help pay that down. He began the talk by describing the infrastructure and how it came about: Gnome-shell implements its own toolkit, St, which stands for "shell toolkit". It is made accessible by implementing the GObject interfaces in atk. To make a toolkit accessible means adding a way to extract information from it in a standard way; you don't want screen readers to have separate implementations for GTK, Qt, St, Firefox, etc. For every window, regardless of toolkit, you want to have a "list children" method. For every widget you want "get accessible name", so for a button it may tell you "OK button", and for an image it may tell you "thumbnail of file.jpg". For widgets that you can interact with, you want "list actions" and "run action X", so a button may present an "activate" action, and a check button may present a "toggle" action.

However, ATK is just abstract interfaces for the benefit of toolkits. We need a way to ship the information extracted from toolkits to assistive tech like screen readers. The atspi protocol is a set of DBus interfaces that an application must implement; atk-adaptor is an implementation of those DBus interfaces that works by calling atk's slightly different interfaces, which in turn are implemented by toolkits. Atk-adaptor also caches some things that it already asked to the toolkit, so it doesn't have to ask again unless the toolkit notifies about a change.

Does this seem like too much translation going on? It is! We will see the reasons behind that when we talk about how accessibility was implemented many years ago in GNOME.

[$] Oaxaca, Endless OS, and indigenous languages

목, 2022/08/04 - 5:29오전
A rural Mexican state was the setting for an initiative to use the GNOME-based Endless OS to improve education in indigenous communities. Over the last several years, the Endless OS Foundation has teamed up with the Fundación Alfredo Harp Helú Oaxaca (FAHHO) to deliver offline-first computers to those communities, but also to assist these communities in preserving their native languages. In a talk at GUADEC 2022, Rob McQueen provided a look at the project and what it has accomplished.

Vetter: Locking engineering hierarchy

수, 2022/08/03 - 10:42오후
Daniel Vetter continues his series on locking in the kernel.

This part goes through a pile of locking pattern and designs, from most favourable and easiest to adjust and hence resulting in a long term maintainable code base, to the least favourable since hardest to ensure it works correctly and stays that way while the code evolves. For convenience even color coded, with the dangerous levels getting progressively more crispy red indicating how close to the burning fire you are! Think of it as Dante’s Inferno, but for locking.

[$] Crosswords for GNOME

수, 2022/08/03 - 5:32오전
Jonathan Blandford, who is a longtime GNOME contributor—and a cruciverbalist for longer still—thought it was time for GNOME to have a crossword puzzle application. So he set out to create one, which turned into something of a yak-shaving exercise, but also, ultimately, into Crosswords. Blandford came to GUADEC 2022 to give a talk describing his journey bringing this brain exerciser (and productivity bane) to the GNOME desktop.

Go 1.19 released

수, 2022/08/03 - 3:09오전
Version 1.19 of the Go programming language has been released. "Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before". This release includes some memory-model tweaks, a LoongArch port, improvements in the documentation-comment mechanism, and more.

[$] Some 5.19 development statistics

화, 2022/08/02 - 2:23오전
The 5.19 kernel was released, after a one-week delay to deal with the fallout from the Retbleed mitigations, on July 31. By that time, 16,399 commits (15,134 non-merge and 1,265 merges) had found their way into the mainline repository, making this development cycle the busiest since 5.13 (16,030 non-merge changesets and 1,157 merges). Tradition dictates that now is the time for a look at where the changes in 5.19 came from, and we've learned not to go against tradition.

The 5.19 kernel is out

월, 2022/08/01 - 7:29오전
Linus has released the 5.19 kernel.

On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It's something I've been waiting for for a _loong_ time, and it's finally reality, thanks to the Asahi team. We've had arm64 hardware around running Linux for a long time, but none of it has really been usable as a development platform until now.

He also notes that the next kernel is likely to be 6.0.

Significant features in 5.19 include Arm Scalable Matrix Extension support, a number of io_uring improvements, BIG TCP support, numerous random-number generator improvements, support for AMD's Secure Nested Paging and Intel's Trusted Domain Extensions mechanisms, support for the Loongson "LoongArch" CPU architecture, a new proactive reclaim mechanism, and more. See the LWN merge-window summaries (part 1, part 2) and the KernelNewbies 5.19 page for more information.
