For years we have had occasional requests to be able to receive LWN in a format for ebook readers. It took a while, but we are now happy to announce that all of LWN's feature content is available, to subscribers at the "professional hacker" level and above, in the EPUB format. To obtain the weekly edition as an EPUB file, just click the "Download EPUB" link in the left column. There is a separate RSS feed for the EPUB format as well. Any other feature content can be turned into an ebook by appending /epub to its URL.

We will also be creating special EPUB books at times. As an example of what is possible, our complete coverage from Kangrejos 2024 and the 2024 Linux Storage, Filesystem, Memory Management, and BPF Summit are available to all readers.

There are surely places where our EPUB books can be improved; please feel free to drop us a note (at lwn@lwn.net) with suggestions.

Security researcher RyotaK has shared a series of vulnerabilities that all have to do with how Git interfaces with external credential managers. In short, while Git guards against newline characters (\n) being injected into a repository's URL, some programming languages also treat carriage return characters (\r) as being newlines. Adding a carriage return to a repository's URL can cause Git and the credential manager to disagree on how the URL should be parsed, ultimately resulting in Git credentials being sent to the wrong host. Malicious repositories could include Git submodules with malformed URLs, triggering the bug. Only password-based authentication with an external credential manager is vulnerable to this attack; SSH-based authentication remains secure. The Git project has chosen to consider this a vulnerability in Git, given the large amount of external software affected. The project has fixed the bug on its end by releasing updates for all supported versions that ban carriage returns in URLs entirely.

Affected software includes GitHub Desktop, Git LFS, and possibly other Git utilities:

Since Git itself doesn't use .lfsconfig file, specifying the URL that contains the newline character in .lfsconfig causes Git LFS to insert the newline character into the message, while bypassing [...] Git's validation.

Earthstar is a privacy-oriented, offline-first, LGPL-licensed database intended to support distributed applications. Unlike other distributed storage libraries, it focuses on providing mutable data with human-meaningful names and modification times, which gives it an interface similar to many non-distributed key-value databases. Now, the developers are looking at switching to a new synchronization protocol — one that is general enough that it might see wider adoption.

Ubuntu will be moving its "official realtime communications channels" from IRC to Matrix, beginning March 1, 2025, following a discussion on the ubuntu-devel mailing list.

"Official" communication, such as making realtime requests of privileged Ubuntu developer teams, could be expected to be actioned if requested on Matrix only. Similarly, you can consider your social responsibility to other developers in relation to your work in Ubuntu development to be fulfilled if you are present on that platform. And Canonical will follow in its requirement for its employed Ubuntu developers to be present on that agreed platform during their working hours.

KaOS is a desktop Linux distribution that features the latest version of the KDE desktop environment, the Calligra office suite, and other popular software applications that use the Qt toolkit. It was inspired by Arch Linux, but the developers build their own packages which are available from in-house repositories. KaOS employs a rolling-release development model and is built exclusively for 64-bit computer systems.

The Meerkat mini PC now ships with either the Intel Core Ultra 7 125H processor with up to 4.5GHz and 14 cores16 cores or the Intel Core Ultra 7 155H processor with up to 4.8GHz and 16 cores, and integrated Intel ARC graphics, as well as up to 96 GB dual-channel DDR5 5600 MHz RAM, and up to 16 TB M.2 PCIe Gen4 NVMe storage.

A Virtual Private Network is a technology solution used to provide privacy and security for inter-network connections. The most well-known case consists of people connecting to a remote server with traffic going through a public or insecure network (such as the Internet).

In this article, we will explain how to set up a VPN server in an RHEL 9 server using OpenVPN, a robust and highly flexible tunneling application that uses encryption, authentication, and certification features of the OpenSSL library.

For simplicity, we will only consider a case where the OpenVPN server acts as a secure Internet gateway for a client.
