Stable kernels 5.8.10, 5.4.66, and 4.19.146

Thursday 17th of September 2020 04:05:21 PM
Greg Kroah-Hartman has announced the release of the 5.8.10, 5.4.66, and 4.19.146 stable kernels. They contain important fixes throughout the tree and users should upgrade.

GNOME's new versioning scheme

Thursday 17th of September 2020 03:22:35 PM
The GNOME Project has announced a change to its version-numbering scheme; the next release will be "GNOME 40". "After nearly 10 years of 3.x releases, the minor version number is getting unwieldy. It is also exceedingly clear that we're not going to bump the major version because of technological changes in the core platform, like we did for GNOME 2 and 3, and then piling on a major UX change on top of that. Radical technological and design changes are too disruptive for maintainers, users, and developers; we have become pretty good at iterating design and technologies, to the point that the current GNOME platform, UI, and UX are fairly different from what was released with GNOME 3.0, while still following the same design tenets."

[$] The seqcount latch lock type

Thursday 17th of September 2020 02:49:46 PM
The kernel contains a wide variety of locking primitives; it can be hard to stay on top of all of them. So even veteran kernel developers might be forgiven for being unaware of the "seqcount latch" lock type or its use. While this lock type has existed in the kernel for several years, it is only being formalized with a proper type declaration in 5.10. So this seems like a good time to look at what these locks are and how they work.

[$] News from PHP: releases, features, and syntax

Wednesday 16th of September 2020 11:25:40 PM
As the PHP project nears its 8.0 release, which is currently slated for late November, there are a number of interesting things to report from its development mailing list. For one, the syntax of the attributes feature has finally been settled on after an acrimonious debate largely over the minutiae of the voting process. In addition, some releases were made and a new proposal to add any() and all() as core library functions was discussed.

[$] Key signing in the pandemic era

Wednesday 16th of September 2020 11:19:07 PM
The pandemic has changed many things in our communities, even though distance has always played a big role in free software development. Annual in-person gatherings for conferences and the like are generally paused at the moment, but even after travel and congregating become reasonable again, face-to-face meetings may be less frequent. There are both positives and negatives to that outcome, of course, but some rethinking will be in order if that comes to pass. The process of key signing is something that may need to change as well; the Debian project, which uses signed keys, has been discussing the subject.

GNOME 3.38 released

[$] BPF in GCC

Tuesday 15th of September 2020 11:46:37 PM
The BPF virtual machine is being used ever more widely in the kernel, but it has not been a target for GCC until recently. BPF is currently generated using the LLVM compiler suite. Jose E. Marchesi gave a pair of presentations as part of the GNU Tools track at the 2020 Linux Plumbers Conference (LPC) that provided attendees with a look at the BPF for GCC project, which started around a year ago. It has made some significant progress, but there is, of course, more to do.

Moment.js announces legacy status

Tuesday 15th of September 2020 03:02:03 PM

Moment.js, the de facto standard JavaScript library for date and time manipulation, has announced that "we would like to discourage Moment from being used in new projects going forward." The project cited multiple reasons for the recommendation. The first is that moment objects are mutable; another is the unnecessarily large size of the library when compared to other internationalization and time-zone support options available to modern browsers. According to the post, "we now generally consider Moment to be a legacy project in maintenance mode. It is not dead, but it is indeed done." The project offers multiple recommendations of alternative options, including "the evolution of Moment", Luxon, authored by long-time Moment.js contributor Isaac Cambron.

[$] Modernizing the tasklet API

Monday 14th of September 2020 03:39:54 PM
Tasklets offer a deferred-execution method in the Linux kernel; they have been available since the 2.3 development series. They allow interrupt handlers to schedule further work to be executed as soon as possible after the handler itself. The tasklet API has its shortcomings, but it has stayed in place while other deferred-execution methods, including workqueues, have been introduced. Recently, Kees Cook posted a security-inspired patch set (also including work from Romain Perier) to improve the tasklet API. This change is uncontroversial, but it provoked a discussion that might lead to the removal of the tasklet API in the (not so distant) future.

Kernel prepatch 5.9-rc5

The 5.9-rc5 kernel prepatch is out for testing. "So aside from the smoke from the fires, and a performance regression I'm still looking at, things look normal."

[$] OpenPGP in Rust: the Sequoia project

Friday 11th of September 2020 04:06:39 PM
In 2018, three former GnuPG developers began work on Sequoia, a new implementation of OpenPGP in Rust. OpenPGP is an open standard for data encryption, often used for secure email; GnuPG is an implementation of that standard. The GPLv2-licensed Sequoia is heading toward version 1.0, with a handful of issues remaining to be addressed. The project's founders believe that there is much to be desired in GnuPG, which is the de facto standard implementation of OpenPGP today. They hope to fix this with a reimplementation of the specification using a language with features that will help protect users from common types of memory bugs.

[$] Android kernel notes from LPC 2020

Thursday 10th of September 2020 04:55:25 PM
In its early days, the Android project experienced a high-profile disconnect with the kernel community. That situation has since improved considerably, but there are still differences between Android kernels and the mainline. As a result, it is not possible to run Android on a vanilla kernel. That situation continues to improve, though; much evidence to that effect was on display during the Android microconference at the 2020 Linux Plumbers Conference. Several sessions there showed the progress that is being made toward unifying the Android and mainline kernels — and the places where there is still some work to be done.
