Linux 5.18

  • Linux 5.18
    No unexpected nasty surprises this last week, so here we go with the
    5.18 release right on schedule.
    
    That obviously means that the merge window for 5.19 will open
    tomorrow, and I already have a few pull requests pending. Thank you
    everybody. I'd still like people to run boring old plain 5.18 just to
    check, before we start with the excitement of all the new features for
    the merge window.
    
    The full shortlog for the last week is below, and nothing really odd
    stands out. The diffstat looks a bit funny - unusually we have parsic
    architecture patches being a big part of it due to some last-minute
    cache flushing fixes, but that is probably more indicative of
    everything else being pretty small.
    
    So outside of the parisc fixes, there's random driver updates
    (mellanox mlx5 stands out, again likely because everything else is
    small), some other minor architecture fixes, some core networking, and
    some tooling stuff. And random small noise. People who really care for
    the details please just scroll down..

  • The 5.18 kernel has been released [LWN.net]

    Linus has released the 5.18 kernel. "No unexpected nasty surprises this last week, so here we go with the 5.18 release right on schedule." Some of the headline changes in this release include the DAMOS memory-management interface, a number of random-number-generator improvements, the Intel software-defined silicon driver, strict memcpy() bounds checking, a switch to the C11 standard, and more. Also, the Reiserfs filesystem has been deprecated and the last vestiges of a.out support have been removed. See the LWN merge-window summaries (part 1, part 1) and the KernelNewbies 5.18 page for more details.

  • Linus Torvalds debuts 'boring old plain' Linux kernel 5.18 • The Register

    Linus Torvalds has released version 5.18 of the Linux kernel.

    The maintainer-in-chief’s post announcing the release was typical of those he made for each of the eight release candidates: this time around he found no nasty surprises, additions were neither major nor complex, and no glitches impacted the development process.

    Torvalds called for developers to "run boring old plain 5.18" before getting excited about the forthcoming version 5.19.

    That description is a little harsh on the new cut of the kernel, which offers notable additions such as the software-defined silicon code that verifies cryptographically signed licenses to enable dormant features in Intel silicon.

    We asked Intel about this, again, and the company still won't share specifics. We were told that Intel is "committed to developing flexible solutions that meet the unique demands of our customers and partners and lead the industry" and "At this time we have no specific product details to share regarding feature activation."

    The mention of "feature activation" is at least new, and admission of intent from Intel. The Register will keep watching this one.

  • Linux kernel 5.18 arrives: Here's what's new | ZDNet

    Linux creator Linux Torvalds has announced the stable Linux kernel version 5.8 release after making it through the final week of development with "no unexpected nasty surprises".

    As usual, Torvalds announced the latest stable release of the Linux kernel on Sunday evening. It was on time and about two months after the stable 5.17 release, thus opening the merge window for Linux 5.19.

    Torvalds had little exciting to say about Linux 5.18 but still encouraged developers to run it.

    "I'd still like people to run boring old plain 5.18 just to check, before we start with the excitement of all the new features for the merge window," wrote Torvalds.

    Still there were "random driver updates" as well as "some other minor architecture fixes, some core networking, and some tooling stuff."

    Linus Torvalds has announced the release of the latest Linux kernel version 5.18, bringing with it the usual masses of improvements and new hardware support. Seems like it was a quiet one when it comes to releasing, with Torvalds jokingly calling it "boring old plain 5.18".

Linux 5.18 Release Could Be Bad News for Overclockers

  • Linux 5.18 Release Could Be Bad News for Overclockers

    The Linux kernel developers have announced version 5.18 of the stable Linux kernel, with a feature that could affect future Intel processors by limiting CPUs unless users pay for upgrades to unlock features that already exist on the silicon.

Clickbait again

  • The latest Linux kernel release is actually really boring, Torvalds says | TechRadar

    Linus Torvalds has released the 5.18 version of the Linux kernel on schedule, but he hardly sounds happy about it

    Torvalds said “nothing really odd stands out” for users of Linux distros from the latest 5.18 update, dubbing the kernel “plain old boring 5.18”.

    The news means that the merge window for the soon to land 5.19 kernel will open within hours, hopefully providing loyal users with a bit more excitement.

  • Linux Kernel 5.18 Includes a Controversial Intel Driver + More - OMG! Linux

    A new version of the Linux kernel has been released.

    Announced by Linux kernel creator Linus Torvalds on the Linux Kernel Mailing List, Linux 5.18 offers a number of improvements in hardware and driver support, improves file system functionality and performance enhancements, and boosts system security.

    Among the notable changes in Linux 5.18 is a controversial new driver from Intel. Their ‘Software Defined Silicon’ (SDSi) driver allows the chip vender to restrict specific processor features unless a license (from Intel) is purchased and present..

    Linux 5.18 has been released a bit over a week ago. As usual, we recommend the resources provided by LWN.net (part 1 and part 2) and KernelNewbies.org to get an overall view of the major features and improvements of this Linux kernel release.

    Bootlin engineers have collectively contributed 80 patches to this Linux kernel release, making us the 28th contributing company according to these statistics.

Statistics from the 5.18 development cycle

  • Statistics from the 5.18 development cycle

    The 5.18 kernel was released on May 22 after a nine-week development cycle. That can only mean that the time has come to look at some of the statistics behind this release, which was one of the busiest in a while. Read on for a look at the 5.18 kernel, where the code in this release came from, and how it found its way into the mainline.

    The 5.18 development cycle saw the addition of 14,954 non-merge changesets from 2,024 developers, 289 of whom made their first kernel contribution during this time. None of these numbers are records, though the number of developers came close to the maximum seen so far (2,062 for 5.13). This work resulted in the addition of 756,00 lines of code to the kernel.

  • 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.
