Kernel: AMD SMCA Updates, STM32MP1, and Rust

Filed under
Linux
  • AMD SMCA Updates
    Hi all,
    
    This set adds supports for SMCA changes in future AMD systems.
    
    Patch 1 adds an "unknown" bank type so that sysfs initialization issues
    can be avoided on systems with new bank types.
    
    Patch 2 adds new bank types and error descriptions used in future AMD
    systems.
    
    Patch 3 adjusts how SMCA bank information is cached. Future AMD systems
    will have different bank type layouts between logical CPUs. So having a
    single system-wide cache of the layout won't be correct.
    
    Thanks,
    Yazen

  • Updated Rust Code For Linux Kernel Patches Posted - Phoronix

    In 2022 we will very likely see the experimental Rust programming language support within the Linux kernel mainlined. Sent out this morning were the updated patches introducing the initial support and infrastructure around handling of Rust within the kernel.

    This summer saw the earlier patch series posted for review and discussion around introducing Rust programming language support in the Linux kernel to complement its longstanding C focus. In the months since there has been more progress on enabling Rust for the Linux kernel development, Linus Torvalds is not opposed to it, and others getting onboard with the effort. Rust for the Linux kernel remains of increasing interest to developers over security concerns with Rust affording more memory safety protections, potentially lowering the barrier to contributing to the kernel, and other related benefits.

  • The Linux Kernel's Second Language? Rust Gets Another Step Closer - Slashdot

    "In 2022 we will very likely see the experimental Rust programming language support within the Linux kernel mainlined," writes Phoronix, citing patches sent out Monday "introducing the initial support and infrastructure around handling of Rust within the kernel."

Patch suggests Rust may be the next frontier for Linux kernel

  • Patch suggests Rust may be the next frontier for Linux kernel

    The Linux kernel has maintained portability due to reliance on the C programming language, but serious adoption of Rust now threatens its dominance.

    Mozilla’s decade old technology has become a major force, offering the same level of flexibility afforded by classic compiled languages, while offering interoperability with C. Kernel developers have long discussed the possibility of bringing Rust to Linux, and the Linux kernel now includes a stable Rust compiler. This has led Kernel developer Miguel Ojeda to introduce a patch that would make Rust its second official language.

Microsoft-controlled "Rust for Linux"

  • Rust for Linux Progresses with New Abstractions and Infrastructure [Ed: Linux the kernel -- not just Linux Foundation -- increasingly being controlled by the Microsoft, i.e. the thugs who attack him internationally]

    A new patch for Linux advances support for Rust as a second language for kernel development. Besides updating the infrastructure and providing new abstractions around kernel features, the new patch sets the base for more frequent submissions, writes Rust for Linux project lead Miguel Ojeda.

    The new patch comes a few months after the initial contribution setting the stage for using Rust for drivers and modules and taking advantage of its superior memory safety model.

    With the new submission, Rust for Linux moved to using the latest stable release of the Rust compiler, version 1.57.0. The objective here is not relying eventually on any unstable language features and being able to declare a minimum Rust version required for kernel development. The new infrastructure also includes a number of new diagnostics and clippy lints to ensure stricter checks.

  • Rust in the Linux Kernel: ‘Good Enough’

    The effort to bring Rust to the Linux kernel marches on this week, with an update from Rust for Linux project maintainer Miguel Ojeda put out this week serving as cause for renewed excitement. While the update cautions that Rust support is “still to be considered experimental,” it notes that the project has moved on from using the beta Rust compiler to use stable releases, starting with Rust 1.57.0, which was just released last Thursday.

    In addition, the project has migrated to the 2021 edition of Rust, and plans to migrate to new stable compilers each time one is released.

  • Hudi powering data lake efforts at Walmart and Disney+ Hotstar

    The open source Apache Hudi data lake project is helping power large deployments at a number of big enterprises, including Uber, Walmart and Disney+ Hotstar. Apache Hudi (Hadoop Upserts, Deletes and Incrementals) is a technology that was originally developed at Uber in 2016 and became an open source project the following year. In June 2021, Hudi became a Top-Level Project at the Apache Software Foundation, which was a major milestone for the project's maturity. Hudi provides a series of capabilities for data lakes, including a table format and services that enable organizations to effectively manage data for data queries, operations and analytics.

  • Aditi’s Open Source Journey

    Hi! I am Aditi from India. According to Wikipedia, India annually produces 1M engineering graduates! (Yep! That’s a lot). And I am one of the 1M graduating in 2022. Just like most people, when I started studying back in 2018, I was pretty lost! I spent my first three semesters trying to find a perfect road-map to being a good developer in a sea of infinite possibilities, skimming through various options. I wasn’t sure what I was going to do, I just knew, I liked being in the field! It took me 1.5 years to realize that there is no perfect roadmap, it’s just as simple as when you start something, you like it, you stay consistent and end up in the right place! [...] One of the best pieces of advice I received from her: “Switch from Windows to Linux!” [...] I finished my outreachy initial application and devoted all my time in finding the perfect organization. That’s when I found GNOME. The skills required were C++ and JS – two languages I knew I had some experience in and liked working with. The GNOME community was indeed awesome. I never felt like an outsider. And that’s when I met Philip Chimento, one of the best mentors I’ve ever had. I remember being super excited when I finished building my first small app using GJS! (It just read a file and returned the number of lines, but it worked and that felt like a good enough reason to go on! :D). I couldn’t wait to officially start my internship with GNOME but my Outreachy initial application got rejected again because of time commitment issues.

  • Fileless Malware on Linux: Anatomy of an Attack | LinuxSecurity.com

    Recent years have demonstrated that Windows users are not the only ones who should be concerned about malware. Linux is becoming an increasingly popular target among malware operators due to the growing popularity of the open-source OS and the high-value devices it powers worldwide. Security researchers from AT&T Alien Labs are now warning that “cyber gangs have started infecting Linux machines via a fileless malware installation technique that until recently was more commonly used against Windows-based systems”. So what exactly is fileless malware and how does a fileless malware attack on Linux work? This article will provide you with answers to these questions by honing in on the anatomy of a Linux fileless malware attack - equipping you with the knowledge necessary to secure your systems and your data against this stealthy and malicious threat. Let’s begin by exploring the concept of fileless malware.

This End Times Cyberdeck Is Apocalypse-Ready'

In the cyberdeck world, some designs are meant to evoke a cyberpunk vibe, an aesthetic that’s more lighthearted than serious. Some cyberdecks, though, are a little more serious about hardening their designs against adverse conditions. That’s where something like the ARK-io SurvivalDeck comes into play. Granted, there does seem to be at least a little lightheartedness at play with the aptly named [techno-recluse]’s design. It’s intended to be an “Apocalypse Repository of Knowledge”, which may be stretching the point a bit. But it does contain an impressive amount of tech — wide-band software defined radio (SDR) covering HF to UHF, GPS module, a sensor for air pressure, temperature, and humidity, and a Raspberry Pi 3B running Kali Linux. Everything is housed in a waterproof ammo can; a 3D printed bezel holds an LCD touchscreen and a satisfying array of controls, displays and ports. The lid of the ammo can holds a keyboard, which was either custom-made to precisely fit the lid or was an incredibly lucky find. Read more
