Fedora moves towards Forgejo (Fedora Magazine)

✇LWN
Par : jzb

Fedora Project Leader Matthew Miller reports that the project's search to replace Pagure as its git forge is almost complete, with the Fedora Council strongly in favor of Forgejo:

The Council, currently, has a clear preference for Forgejo. This is a big decision and we don't want it to feel rushed. Therefore, we're opening this up one last time to everyone's comments. After two weeks, we'll take our formal vote — and then get on with the work!

LWN looked at Forgejo in February.

Walleij: New ARM32 Security Features in v6.10

✇LWN
Par : corbet
Linus Walleij writes about a pair of security features for 32-bit Arm systems; these landed in 6.10, but, he says, have now stabilized to the point that distributors may want to enable them.

PAN is an abbreviation for the somewhat grammatically incorrect Privileged Access Never. [...]

For modern ARM32 systems with large memories configured to use LPAE nothing like PAN was available: this version of the MMU simply did not implement a PAN option.

As of the patch originally developed by Catalin Marinas, we deploy a scheme that will use the fact that LPAE has two separate translation table base registers (TTBR:s): one for userspace (TTBR0) and one for kernelspace (TTBR1).

[$] The return of RWF_UNCACHED

✇LWN
Par : corbet
Linux offers two broad ways of performing I/O to files. Buffered I/O, which is the usual way of accessing a file, stores a copy of the transferred data in the kernel's page cache to speed future accesses. Direct I/O, instead, moves data directly between the storage device and a user-space buffer, avoiding the page cache. Both modes have their advantages and disadvantages. In 2019, Jens Axboe proposed an uncached buffered mode to get some of the advantages of both, but that effort stalled at the time. Now, uncached buffered I/O is back with some impressive performance results behind it.

Hurl 6.0.0 released

✇LWN
Par : jzb

Version 6.0.0 of the Hurl command-line tool has been released. Hurl is curl-powered utility that runs HTTP requests and tests defined in a plain-text Hurl file. Notable features in this release include the ability to generate dynamic values with functions, shorter syntax, and an option to export Hurl files to a list of curl commands. See the release notes for a full list of changes and downloads.

[$] Rust's incremental compiler architecture

✇LWN
Par : daroc

The traditional structure of a compiler forms a pipeline — parsing, type-checking, optimization, and code-generation, usually in that order. But modern programming languages have requirements that are ill-suited to such a design. Increasingly, compilers are moving toward other designs in order to support incremental compilation and low-latency responses for uses like integration into IDEs. Rust has, for the last eight years, been pursuing a particularly unusual design; in that time compile times have substantially improved, but there's still more work to be done.

[$] The rest of the 6.13 merge window

✇LWN
Par : corbet
The 6.13 merge window closed with the release of 6.13-rc1 on December 1. By that time, 11,307 non-merge commits had been pulled into the mainline repository; about 9,500 of those landed after our first-half merge-window summary was written. There was a lot of new material in these patches, including architecture-support improvements, new BPF features, an efficient way to add guard pages to an address space, more Rust support, a vast number of new device drivers, and more.

Kernel prepatch 6.13-rc1

✇LWN
Par : corbet
Linus has released 6.13-rc1 and closed the merge window for this release. "And for once - possibly the first time ever - it looks like the release cycle doesn't clash horribly up with the holiday season, and we'll have time both to stabilize this release, _and_ the work for 6.14 won't be starting until well into January."

Rust 1.83.0 released

✇LWN
Par : corbet
Version 1.83.0 of the Rust language has been released.

This release includes several large extensions to what code running in const contexts can do. This refers to all code that the compiler has to evaluate at compile-time: the initial value of const and static items, array lengths, enum discriminant values, const generic arguments, and functions callable from such contexts (const fn).

There are also quite a few new stabilized APIs.

The OpenWrt One router is now shipping

The OpenWrt One router, which was reviewed here recently, is now generally available.

This is the first wireless Internet router designed and built with your software freedom and right to repair in mind. The OpenWrt One will never be locked down and is forever unbrickable. This device services your needs as its owner and user. Everyone deserves control of their computing. The OpenWrt One takes a great first step toward bringing software rights to your home: you can control your own network with the software of your choice, and ensure your right to change, modify, and repair it as you like.

Giving thanks for the LWN community

Earlier today, one of our subscribers, anselm, posted the one millionth item in our database during a discussion in the comments about the GPL. One million articles and comments is a big milestone — one representing twenty two years of work by both the editors of LWN and the community. I think reaching this milestone on Thanksgiving is a lovely coincidental reminder of how far LWN has come, and how that wouldn't have been possible without your support. So thank you for reading.

Elementary OS 8 released

✇LWN
Par : jzb

Version 8 of the Ubuntu-based elementary OS has been released. This release includes a rewritten Dock, new window-management features, improvements in the installation and initial setup procedures for visually impaired users, as well as a new Secure Session mode:

In the Secure Session, apps will be more restricted and will require your consent for access to system features. When an app wants to listen in the background for your keystrokes, take a screenshot, record the screen, or even pick up the color from a single pixel, you will be asked first to make sure that it's okay. The Secure Session also comes with other modern features like support for Mixed DPI modes—A hotly requested feature for folks using a HiDPI notebook or tablet with a LoDPI external display—and improved support for multi-touch gestures on touch screens and tablets.

[$] The kernel's command-line commotion

✇LWN
Par : corbet
For the most part, the 6.13 merge window has gone smoothly, with relatively few problems or disagreements — other than this one, of course. There is one other exception, though, relating to the kernel's presentation of a process's command line to interested user-space observers when a relatively new system call is used. A pull request with a simple change to make that information more user-friendly ran afoul of Linus Torvalds, who has his own view of how it should be managed.

[$] Arch Linux finally starts licensing PKGBUILDs

✇LWN
Par : jzb

Arch Linux is popular as a base for other Linux distributions; examples of Arch-derivatives include EndeavourOS, Manjaro, Parabola, and SteamOS. There's one small problem: the control files used to describe how to build packages for Arch Linux have no stated license. That creates a bit of uncertainty about the rights and responsibilities for the downstream derivatives. So far, that doesn't seem to have been a problem, nor has it stopped other projects from assuming that reuse is allowed. However, the Arch project is looking to add some clarity by explicitly assigning a liberal license to its package sources. Currently the project is in the process of reaching out to contributors to see if they have any objections.
