Opinions of Greg Crow-Hartman and Case Cook on promoting Rust into the Linux kernel

Posted on

Greg Kroah-Hartman, who is responsible for maintaining the stable branch of the Linux kernel, has voiced support for the development of new kernel components in the Rust language. As someone who has been the conduit for information on bugs and vulnerabilities in the Linux kernel for the past 15 years, he claims that most kernel errors are caused by unaccounted corner cases in the C language, which are completely avoided […]

Linus Torvalds intends to include Rust-related changes bypassing maintainers

Posted on

Christoph Hellwig, maintainer of the DMA, KVM, Slab Allocator subsystems, and PowerPC architecture in the Linux kernel, has fundamentally refused to accept Rust bindings for the DMA subsystem into the kernel and has joined the discussion on the rules for supporting Rust as part of the kernel, published by the Rust for Linux project. In Christoph's opinion, such rules are useless until they are agreed upon with the community and included in […]

RAR Archiver 7.10

The release of the proprietary archiver RAR version 7.10 has taken place. The change list for the console version: 32-bit versions of Linux and FreeBSD for x86 are no longer supported. The name of the environment variable that stores the default set of RAR keys has been changed from RAR to RARINISWITCHES. It is quite typical for batch files to use the environment variable name RAR to store the path to the RAR executable, […]

openSUSE is testing support for reproducible builds

Posted on

Developers of the openSUSE distribution have reported successes in the project aimed at ensuring support for reproducible builds. As part of the project, a conceptual fork of the distribution, Reproducible-openSUSE (RBOS), has been prepared, which has achieved the ability to build 100% identical binary packages based on the proposed repository of source texts, totaling 3300 packages. In the course of the work on the project, about 40 patches (1, 2, 3) have been prepared to solve issues with […]

On February 15, version 6.13 of the btrfs-progs console utility set for working with the Btrfs file system in a user environment was released. One significant change in this version is the addition of the --compress option to the mkfs.btrfs utility. With this new option, you can enable and configure the compression algorithm and its level. It should be used in conjunction with the --rootdir argument to specify […]

OpenSSH 9.9p2 update with the removal of the possibility to perform a MITM attack

Posted on

A corrective release of OpenSSH 9.9p2 has been made available, which addresses two vulnerabilities identified by Qualys. An example of exploiting these vulnerabilities for a MITM attack was demonstrated, allowing traffic intended for an SSH server to be redirected to a malicious server, bypass the host key verification, and create the illusion for the client that they are connected to the desired server (the ssh client will accept the host key of the fake server instead of the key [...])

The project is now in the hands of Jens Persson, co-author of the Panucci application for playing podcasts and audiobooks. The work on the port is not yet complete, but the latest in the project repository [...]

SUSE and openSUSE are considering ending BIOS boot support

Posted on

Luboš Kocman, responsible for preparing openSUSE releases, announced that SUSE is considering ending BIOS boot support, which would prevent the use of SUSE and openSUSE distributions on systems lacking UEFI support. The desire to discontinue BIOS support is explained by the fact that starting with the SLES 16 and openSUSE Leap 16 releases, package builds will be made for architectures [...]
