  • That Didn't Take Long: KSMBD In-Kernel File Server Already Needs Important Security Fix - Phoronix

    It was just a few weeks back that KSMBD was merged into Linux 5.15 while now it's seeing its first important security fix.

    When KSMBD as an in-kernel SMB3 file server was first talked about, many expressed concerns in the name of security even though NFS exists within the kernel, etc. This weekend's security vulnerability for KSMBD is an issue leading to files outside of the SMB3 file share being accessible to clients...

  • Linux 5.16 To Support Sensor Readings On More ASUS Motherboards - Phoronix

    With a change to the nct6775 hardware monitoring sensor driver, more ASUS motherboards should enjoy working sensor support come Linux 5.16.

    The changed queued up this week via the "HWMON" hardware monitoring subsystem's "for-next" branch for Linux 5.16 allows the nct6775 driver to access the ASIC using ASUS WMI functions. The driver's existing functionality doesn't work on ASUS motherboards since ACPI marks the I/O port as used so instead the ASUS WMI functions will be used in such case.

  • An OpenCL frontend written in Rust is being developed for Mesa

    Red Hat’s Karol Herbst, who is involved in the development of Mesa, the Nouveau driver, and the OpenCL open stack, has published rusticl , an experimental software implementation of OpenCL (OpenCL frontend) for Mesa written in Rust. Rusticl acts as an analogue of the frontend already present in Mesa OpenCL Clover and is also developed using the interface provided in Mesa Gallium .

    The development was presented on September 17 at the conference XDC 2021 (X.Org Developers Conference). The goal of the development was to study Rust, work out the best ways to integrate Rust into Mesa, try out creating API implementations in another language, and test the compatibility of Rust components with the rest of the C code. Development is not yet fully completed – CL CTS tests related to copying, reading and writing buffers are already successfully running, but compiler integration is not yet provided and there is no support for external crate packages in the build system. To generate bindings for Mesa and OpenCL, allowing cause Rust-functions in C code and vice versa, is involved rust-bindgen .

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.
