linux kernel changelog

Linux_5.8 Released Sun, 2 August 2020 (64 days) . These tests are able to be run locally on a developer's workstation without a VM or special hardware - using the User-Mode Linux architecture. Linux guests: kernel module build fixes for various kernels (bugs #18677 and #18697; fixes by Larry Finger and Gianfranco Costamagna) Linux guests: udev rules for guest kernel modules did not always take effect in time VirtualBox 5.2.30 (released May 13 2019) This is a maintenance release. Two use-cases driving this work are: 1) steer packets destined to an IP range, fixed port to a single socket, 2) steer packets destined to an IP address, any port to a single socket. Linux 5.9 has been released on Sun, 11 Oct 2020.

It will unify the power model for thermal subsystem. This gives great flexibility for users to examine kernel data structure without using e.g. The Linux kernel is a free and open-source, monolithic, modular, multitasking, Unix-like operating system kernel. See all current changelogs here: http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/ https://launchpad.net/ubuntu/+source/linux/+changelog; That should tell you what changed in … A well-written changelog for that code change can help determine if that code can be removed or how it can be modified. This model allows taking advantage of the inline encryption hardware that is integrated into the UFS or eMMC host controllers on most mobile SoCs commit, commit, commit, commit, commit, commit, commit, commit, bcache: extent bucket_size from 16bit to 32bit width. It turns out, quite a bunch of projects need to do exactly that: service managers, libcs, container runtimes, programming language runtimes/standard libraries (Rust/Python). 2006-09-20 3:25 pm. RPM is a very powerful utility and I hope this small tip will save lot of time. The URLs have a predictable pattern. ZSTD offers good compression rates and very high decompression speeds. Sometimes it's handy to know when the socket gets freed. The following items were fixed and/or added: The current kernel change log is at: https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.17.8. New kernel, new tools and updates. Latest version: For devices which expose a zone capacity that is different to the zone's size, the maximum zonefs file size will be set to the zone's (usable) capacity, not the zone size commit, Filesystem client metrics are sent to all available MDSes once per second now commit, commit, Expose information from afs_vlserver through /proc for debugging commit, Add support to set skb mark value commit, commit, commit, (FEATURED) Implement workingset protection and detection on the anonymous LRU page list. 15 - Major Revision.

This framework presents clustered colored LEDs into an array and allows the user space to adjust the brightness of the cluster using a single file write. The lockdown feature aims to further strengthen Linux security by “restricting access to kernel features that may allow arbitrary code execution via code supplied by userland processes”.. Linux kernel LTSI 4.14.75 add to watchlist send us an update. Announced in the LKML, Linux Kernel 5.9 immediately available for download from the mainline Kernel builds. On battery powered devices, it is desired to control this default (currently hardcoded) behavior at runtime to reduce energy consumed by RT tasks commit, commit, isolation: Isolate unbound kthreads commit, commit, fanotify: report events with names.

Recommended LWn article: Capacity awareness for the deadline scheduler, The FSGSBASE instructions are an Intel feature that has been available for a long time.

If you don't want to use the pre-built kernel and headers, you can compile the kernel yourself following these steps: (Prep) Install the required packages for compiling the kernel: IMPROV: bump Linux kernel to 4.19.46; 2019/05/18 (262) NEW: switch to Linux kernel 4.19; FIX: handle backslashes in wireless passwords; 2019/04/28 (258) NEW: volume support; 2019/04/20 (253) IMPROV: bump Linux kernel to 4.14.112; IMPROV: support native DSD on the Nagra DAC; 2019/04/07 (248) NEW: clock color can be changed to grey, blue or green ARM big.LITTLE), which leads to wrong scheduling decisions.

It was conceived and created in 1991 by Linus Torvalds for his i386 based PC, and it was soon adopted as the kernel for the GNU Operating System, which was created as open source and free software, and based on UNIX as a by-product of the fallout of the Unix wars.

This enables Disqus, Inc. to process some of your data. In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. For general Windows information on build 19028 visit the Windows blog. This release incorporates KUnit, a lightweight unit testing and mocking framework for the Linux kernel.

The –changelog option only works with rpm based package and distro such as RHEL / CentOS / Fedora / Suse etc. What is a typical changelog size for the linux kernel? Among the changes that have been made in the 2.6 series are: integration of µClinux into the mainline kernel sources, PAE support, support for several new lines of CPUs, integration of Advanced Linux Sound Architecture (ALSA) into the mainline kernel sources, support for up to 2 32 users (up from 2 16), support for up to 2 29 process IDs (64-bit only, 32-bit arches still limited to 2 15), substantially increased the … 2.1.3 Linux RDMA Driver • Fixed: When connecting multiple rping clients to a persistent rping server, older kernels might experience a crash related to the handling of cm_id values in the kernel stack. This facility allows admin to forcefully undo BPF link attachment, while process that created BPF link in the first place is left intact. In the previous implementation, newly created or swap-in pages were placed on the active list, which could force actively used pages to the inactive list. In particular, combined with the userspace changes, allows platforms to override default system parameters from a main.conf file commit, commit, commit, le_simult_central_peripheral experimental feature which allows a clients to determine if the controller is able to support peripheral and central connections separately and at the same time commit, Add ethtool extended link state commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, batman-adv: Introduce a configurable per interface hop penalty commit, bonding: initial support for hardware crypto offload commit, commit, commit, commit, mrp: Add support for interconnect ring.

While the bumping was rather arbitrary as opposed to a major change necessitating the big version bump, this next version of the Linux kernel does come with some exciting changes and new features (of course, our Twitter followers already have […] This release incorporates support for extended attributes (RFC 8276), which bridges one of the most relevant gaps in NFS. User can have a bpf program in kernel to run with each map element, do checking, filtering, aggregation, modifying values etc. Aditionally, because these changes can cause newly created or swap-in anonymous pages to swap-out existing pages in the inactive list, workingset detection has been extended to deal with the anonymous LRU list to make more optimal decisions commit, commit, commit, commit, commit, commit, (FEATURED) New cgroup slab memory controller.
