Linux Kernel 4.3.1 Released

Linux was originally developed as a free operating system for personal computers based on the Intel x86 architecture, but has since been ported to more hardware platforms than any other operating system. Thanks to its dominance in smartphones, Android, which is built on top of the Linux kernel, has the largest installed base of all general purpose operating systems installed.

It has been over a month since Linus Torvalds announced the release of Linux kernel 4.3, and we have to admit we were wondering when it would get some maintenance releases. Well, today is that day, as the Linux kernel 4.3.1 was introduced and includes some pretty interesting things. First, in number, Linux kernel 4.3.1 changes files 136, with 1,224 438 insertions and deletions.

“I am announcing the release of the 4.3.1 kernel. All users of the 4.3 kernel series should upgrade,” said Greg Kroah-Hartman. “The updated 4.3.y git tree can be found at: git: linux-4.3.yy //git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git can be found in the kernel.org git normal web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary “.

According shortlog attached, the first maintenance release of the Linux kernel 4.3 brings improvements in dozens of ARM, x86, s390, MIPS, and ARM64 (AArch64) hardware architectures, multiple network upgrades, especially for things like Bluetooth, IPv6 , IPv4, mac80211, NFC, TIPC (transparent communication between processes) and Wi-Fi as well as a pair of USB controllers improvements sound.
Many drivers have been updated

Besides the architecture, networking and sound updates mentioned above, Linux kernel 4.3.1 updated many drivers, especially for things like Bluetooth, CLK, MFD, NFC, PINCTRL, TTY, USB, Xen, and the creation networks (especially wireless and Ethernet). Of course, Linux kernel 4.3.1 also adds some minor improvements under the hood that make Linux 4.3 kernel more reliable and stable.

all users of GNU / Linux running Linux kernel 4.3 for Linux 4.3.1 kernel upgrade as soon as possible, or more precisely as you get to the default software repositories of their operating systems are encouraged. Meanwhile, operating system vendors and experienced users can download the source code of the Linux kernel 4.3.1 right now from Softpedia or kernel.org website and begin compiling by hand.

  • Update
  • Query
  • List
  • Verify

Syntax

RPM filename contains four parts Package Name, Version, Release & Architecture Name

vsftpd-2.2.2-14.el6.i686.rpm

Package Name – vsftpd
Version – 2.2.2-14
Release – el6
Architecture – i686

1) Install an RPM Package

To install an RPM Package on linux machine use the following command.

# rpm -ivh vsftpd-2.2.2-14.el6.i686.rpm

Preparing... ########################################### [100%]
1:vsftpd ########################################### [100%]

where
-i : install
-v : verbose
-h: print hash marks

2) Delete an RPM Package

Preparing... ########################################### [100%]
1:vsftpd ########################################### [100%]

4) Query an RPM Package

To query specific package use -qa option

# rpm -qa|grep vsftpd
vsftpd-2.2.2-14.el6.i686

-q : Query a package

5) List an RPM Package

To view the package list use -ql option

# rpm -ql vsftpd-2.2.2-14.el6.i686.rpm

6) Verify an RPM Package

In order to verify RPM package use the following command

# rpm -Va

Note: There is another easiest method to install,delete,update packages in RedHat/Fedora/CentOS based machine through YUM commands.
