Update / Update to Linux kernel 4.5.2 on Ubuntu / Linux Mint Derivative System

Linux kernel 4.5.2 is released, Available for Ubuntu 16.04 Xenial Xerus, Ubuntu 15.10 wily werewolf, Ubuntu 15.04 vivid Vervet, ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr (LTS), Linux Mint 17.1, Linux Mint 17.2, Linux Mint 17.3 and other Ubuntu derivative systems


Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.

Linux kernel 4.5.2 is the second maintenance build for the latest and most advanced kernel branch, which more and more GNU/Linux operating system are adopting lately, including the popular openSUSE Tumbleweed and Arch Linux rolling distributions.

Includes powerful features

Linux provides users with powerful features, such as true multitasking, multistack networking, shared copy-on-write executables, shared libraries, demand loading, virtual memory, and proper memory management.

Initially designed only for 386/486-based computers, now Linux supports a wide range of architectures, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.

What's new in Linux kernel 4.5.2

Looking at the appended shortlog, Linux kernel 4.5.2 adds minor improvements to the Btrfs, OverlayFS, NFS, and EXT4 filesystems, as well as to the ARM, ARM64 (AArch64), MIPS, PA-RISC, PowerPC (PPC), s390, and x86 architectures. Core kernel, crypto, and sound changes are also present.

Moreover, the networking stack received various enhancements as well, in particular for things like IPv6, IPv4, DSA (Distributed Switch Architecture), Datagram Congestion Control Protocol (DCCP), Layer 2 Tunneling Protocol (L2TP), the mac80211 framework, Multiprotocol Label Switching (MPLS), and the XFRM IP framework.

As with any new maintenance release of a Linux kernel, numerous drivers have been updated, and Linux kernel 4.5.2 includes improvements for GPIO (general-purpose input/output), the AMDGPU open-source video driver, HID, iiO, hwmon, IOMMU, MMC, networking (mostly Ethernet), NVDIMM, PCMCIA, PINCTRL, SCSI, USB, Virtio, and Xen.
