Linux Kernel 4.2 RC3 Released: What's New and How to Install It



This article documents the version history of the Linux kernel. The Linux kernel is a free and open-source, monolithic, Unix-like operating system kernel. It was conceived and created in 1991 by Linus Torvalds.[1]




Linux Kernel 4.2 RC3 Released



Linux kernels have different support levels depending on the version. Usually, each stable version continues to backport bug fixes from the mainline until the next stable version is released. However, if a stable version has been designated a long-term support (LTS) kernel, it will be maintained for extra few years.[2] After that, a few versions got declared Super-Long-Term Support (SLTS) will then be maintained by the Civil Infrastructure Platform for many more years.[3]


Versions 2.6.16 and 2.6.27 of the Linux kernel were unofficially supported in a long-term support (LTS) fashion,[241] before a 2011 working group in the Linux Foundation started a formal long-term support initiative.[242][243]


Fwupd is an open-source daemon for managing the installation of firmware updates on Linux-based systems, developed by GNOME maintainer Richard Hughes. Fwupd 1.8.9 has been released as the latest version of the firmware update solution for Linux systems. It is designed primarily for servicing the Unified Extensible Firmware Interface (UEFI) firmware on supported devices via EFI System Resource Table (ESRT) and UEFI Capsule, which is supported in Linux kernel 4.2 and later.


In 1991, Torvalds, a Finnish student, released Linux to the world. Combined with GNU, Linux soon became a popular kernel and perhaps the most widely used operating system kernel. Articles of ours about Torvalds include the following.


While Xen 4.7 was released this week as the latest for this virtualization hypervisor, the independent Xen Orchestra software that provides a web interface to Xen Server is out with its version 5.0 milestone.


QEMU 2.6-RC3 was released this week and QEMU 2.6.0 should be officially released at the beginning of May. Here's a look at some of the new features coming to this important piece of the Linux open-source virtualization stack.


Landing in the Linux 4.2 kernel was the new VirtIO GPU driver to be used with the open-source Linux virtualization stack as the first step towards having open-source GPU hardware acceleration in guest VMs. While that initial code drop didn't hook up any 3D rendering support, there's now patches for doing just that.


QEMU requires the most recent macOS version that is currently available.Support for the last previous version will be dropped two years after thecurrent version has been released or when Apple drops support for it,whatever comes first.


Major changes include toolchain updates to binutils-2.39, gcc-12.2, and glibc-2.36. In total, 34 packages were updated since the last release. Additionally Python module installation has been changed to use the 'wheel' method for more consistent build/install procedures. Changes to the text have also been made throughout the book. The Linux kernel has been updated to version 5.19.2.


Please direct any comments about this release to the LFS development team at lfs-dev@lists.linuxfromscratch.org. Please note that registration for the lfs-dev mailing list is required to avoid junk email.

The Linux From Scratch community announces the release of LFS Version 11.1. Major changes include toolchain updates to glibc-2.35, and binutils-2.38. In total, 35 packages were updated since the last release. Changes to the text have also been made throughout the book. The Linux kernel has also been updated to version 5.16.9.


In coordination with this release, a new version of LFS using the systemd package is also being released. This package implements the newer systemd style of system initialization and control and is consistent with LFS in most packages. You can read the systemd version of the book online at LFS-systemd, or download-systemd to read locally.


Major changes include toolchain updates to binutils-2.38 and glibc-2.35. In total, 35 packages were updated since the last release. Additionally openssl has bee updated to version 3.0.1. Changes to the text have also been made throughout the book. The Linux kernel has also been updated to version 5.16.9.


This version of the Linux From Scratch book has been released due to a critical security vulnerability in openssl. This vulnerability has been fixed in LFS 11.0-rc3 by updating to the latest version: openssl-1.1.1l (version 1.1.1 lower case L). Usage of LFS 11.0-rc1 or LFS 11.0-rc2 is deemed unsafe and insecure.


In addition to the above, we took the opportunity to update several other pachages from the recent -rc releases to the latest stable versions: e2fsprogs, meson, the linux kernel, util-linux, and libcap.


Major changes include toolchain updates to binutils-2.37 and glibc-2.34. In total, 38 packages were updated since the last release. Changes to the text have also been made throughout the book. The Linux kernel has also been updated to version 5.13.12.


This version of the Linux From Scratch book has been released due to a critical security vulnerability in glibc-2.34. This vulnerability has been fixed in LFS 11.0-rc2 via a simple sed in Chapter 8. Usage of LFS 11.0-rc1 is deemed unsafe and insecure.


Major changes include toolchain updates to binutils-2.37 and glibc-2.34. In total, 38 packages were updated since the last release. Changes to the text have also been made throughout the book. The Linux kernel has also been updated to version 5.13.10.


The Linux From Scratch community announces the release of LFS Version 10.1. Major changes include toolchain updates to glibc-2.33, and binutils-2.36.1. In total, 40 packages were updated since the last release. Changes to the text have also been made throughout the book. The Linux kernel has also been updated to version 5.10.17.


The Linux From Scratch community announces the release of LFS Version 10.1-rc1. It is a preliminary release of LFS-10.1. Major changes include toolchain updates to binutils-2.36.1 and glibc-2.33. In total, 40 packages were updated since the last release. Changes to the text have also been made throughout the book. The Linux kernel has also been updated to version 5.10.17.


Major package updates include toolchain versions glibc-2.32, gccc-10.2.0, and binutils-2.35. In total, 37 packages were updated since the last release. The Linux kernel has also been updated to version 5.8.3. 2ff7e9595c
