Flexible arrays — arrays that are declared as the final member of a structure and which have a size determined at run time — have long drawn the attention of developers seeking to harden the kernel against buffer-overflow vulnerabilities. These arrays have reliably been a source of bugs, so anything that can be done to ensure that operations on them stay within bounds is a welcome improvement. While many improvements, including the recent counted-by work, have been made, one of the most difficult cases remains. Now, however, developers who are interested in using recent compiler bounds-checking features are trying to get a handle on struct sockaddr.

The open-source software (OSS) industry is developing the core software for the global infrastructure, to the point that even some proprietary software giants adopt Linux servers for their cloud services. Still, it has never been able to get organized by creating representative bodies capable of giving an organic response to issues such as those raised at the European level by the Cyber Resilience Act.

Nano is a simple and user-friendly command-line text editor for Linux, which is often used for basic text editing tasks, such as creating and editing configuration files, scripts, or simple documents.

However, many users don’t know that Nano supports syntax highlighting, which can make editing code files easier by coloring different parts of the text (like keywords, variables, and comments) for better visibility.

This guide will explain how to enable syntax highlighting in Nano to make your coding experience smoother and more efficient.

Image-based Linux distributions have seen increasing popularity, recently. They promise reliability and security, but pose packaging problems for existing distributions. Ryan Lahfa and Niklas Sturm spoke about the work that NixOS has done to enable an image-based workflow at this year's All Systems Go! conference in Berlin. Unfortunately, LWN was not able to cover the conference for scheduling reasons, but the videos of the event are available for anyone interested in watching the talks. Lahfa and Sturm explained that it is currently possible to create a NixOS system that cryptographically verifies the kernel, initrd, and Nix store on boot — although doing so still has some rough edges. Making an image-based NixOS installation is similarly possible.

Man pages maintainer Alejandro Colomar announced in September that he was suspending his work due to a lack of support. He has now let it be known that funding has been found for the next year at least:

We've been talking for a couple of months, and we have already agreed to sign a contract through the LF [Linux Foundation], where a number of companies provide the funds for the contract. The contract will cover the next 12 months for the agreed amount, and we should sign it in the following days. Since I've already seen a draft of the contract, and it looks good, I've already started maintaining the project again, starting on Nov 1st.

Umask (a shortcut of user-file creation mode mask) is a Linux command that sets permissions for a file or directory users create. Linux uses this fundamental command to set the default permissions. When creating a new file or directory, the umask command determines the initial access level. We can count umask as a function that sets the mask, which is known as the file mode creation mask.

The next paragraphs will explain how Umask works and how to use the command with the values in different scenarios. Let’s get started!
