In this article, we explain what a linux kernel module is and why they are used with linux operating systems. A linux kernel module is simply a module that represents some feature that can be added to a linux kernel. This feature can be anything such as a security option, a device ...
A Kernel is the core component of any Linux based operating system. It represents the core aspect of the Linux distributions for Desktop computers and servers. It has a monolithic architecture, and the operating system operates entirely in the kernel space. The monolithic kernel not only encircles...
Linux is an open-source operating system (OS) based on Unix that runs on computers, servers, mobile phones and a wide range of other devices.
What driver is needed for EMC XtremSF flash devices? A Linux kernel module, or device driver, for Virident flash storage devices has not yet been provided under an Open Source license, such as the GPL, to enable Red Hat to distribute it with the Linux Kernel. Therefore, it must be obtai...
What driver is needed for Fusion-io ioDrive devices? LVM on Fusion IO drives does not get activated at boot time. A Linux kernel module, or device driver, for Virident flash storage devices has not yet been provided under an Open Source license, such as the GPL, to enable Red Hat to ...
If the operation fails, the kernel will get a SIGBUS (or an alternative signal) to manage the parent process. Nevertheless, if there is a network problem, mkdir might get stuck into an uninterruptible sleep state. The only way to leave this mode is with an explicit wake-up call from the...
/dev/mem is the gateway to the "Physical Address Space" of the processor which might include control registers of many HW peripherals and not just the RAM. In order to prevent attackers from misusing /dev/mem and altering kernel memory, a flagCONFIG_STRICT_DEVMEM needs to be enabled which...
Open vSwitch code is written in C, and provides support for forwarding layer abstraction to different software and hardware platforms.The current releaseof Open vSwitch supports the following key features: High-performance forwarding using a Linux kernel module ...
The kernel lockdown feature comes as a security module for Linux and is disabled by default as it’s intended for Linux developers, device manufacturers, and Linux enterprise distributors. Nonetheless, you can enable and configure it with the lockdown parameter though this will impact all hardware...
Every operating system- whether it is Windows, Mac, Linux, or Android, has a core program called aKernelwhich acts as the ‘boss’ for the whole system. It is the heart of the OS! The Kernel is nothing but a computer program that controls everything else. Anything that happens on the...
