LWN's Coverage From the 2021 Kernel Maintainers Summit

Filed under
  • The 2021 Kernel Maintainers Summit

    The Kernel Maintainers Summit is an invitation-only gathering of top-level kernel subsystem maintainers; it is concerned mostly with process-oriented issues that are not easily worked out on the mailing lists. There was no maintainers summit in 2020; plans had been made to hold it in an electronic form, but there turned out to be a lack of things to talk about. In 2021, though, a number of interesting topics turned up, so an online gathering was held on September 24 as part of the Linux Plumbers Conference.

  • Looking back at the UMN episode

    Earlier this year, a bad patch sent by a researcher from the University of Minnesota (UMN) set off a bit of a crisis within the kernel development community when it become known that some (other) patches from UMN were deliberate attempts to insert vulnerabilities into the kernel. Some months after that episode had been resolved, the 2021 Maintainers Summit revisited the issue to see if there are any lessons to be learned from it.

  • Requirements for accelerator drivers

    In August, a long-running dispute over drivers for AI accelerators flared up in the kernel community. Drivers for graphics accelerators are required to have at least one open-source implementation of the user-space side of the driver (which is where most of the logic is). Drivers for other types of accelerators have not, so far, been held to that same standard, which has created some friction within the community and an inconsistent experience for developers. The 2021 Maintainers Summit took up this issue in the hope of creating a more coherent policy.

  • The trouble with upstreaming

    The kernel development community loudly encourages developers to get their code into the upstream kernel. The actual experience of merging code into the mainline is often difficult, though, to the point that some developers (and their employers) simply give up on the idea. The 2021 Kernel Maintainers Summit spent some time discussing the ways in which the community makes things harder for developers without coming up with a lot of ways to make things better.

  • How to recruit more kernel maintainers

    The kernel development process depends on its subsystem maintainers, who are often overworked and, as a result, grumpy. At the 2021 Kernel Maintainers Summit, Ted Ts'o brought up the topic of maintainer recruitment and retention, but failed to elicit a lot of new ideas from the assembled group.

  • Using Rust for kernel development

    The Rust for Linux developers were all over the 2021 Linux Plumbers Conference and had many fruitful discussions there. At the Maintainers Summit, Miguel Ojeda stepped away from Plumbers to talk about Rust in a different setting. What will it take to get the Rust patches merged? The answers he got were encouraging, even if not fully committal.

    Ojeda started by asking the group whether the community wanted Rust in the kernel. If it goes in, he said, it should do so as a first-class citizen. In his discussions he has encountered a number of kernel developers who are interested in the language; many of them are quite open to it. He has gotten help from a number of those developers in the process. Some groups, including the Android team, actively want it, he said.

  • Conclusion: is Linus happy?

    The final session of the Kernel Maintainers Summit is traditionally given over to Linus Torvalds, who uses the time to talk about any pain points he is encountering in the process and what can be done to make things run more smoothly. At the 2021 Summit, that session was brief indeed. It would appear that, even with its occasional glitch, the kernel development process is working smoothly.

    Torvalds started by saying that the 5.15 merge window was not the easiest he has ever experienced. Part of the problem, he suggested, was that the merge window came at the end of the (northern-hemisphere) summer; much of Europe had been on vacation, and that led to a lot of pull requests showing up at the end of the merge window. In general, though, things are working. His biggest annoyance, perhaps, is having to say the same things over and over during each merge window. The core maintainers know how the process works, those in less central positions tend to make the same mistakes repeatedly; when he takes over 100 pull requests during a merge window, it can add up to a fair amount of irritation.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
