A loadable kernel module (LKM) is an executable library that extends the capabilities of a running kernel, or so-called base kernel, of an operating system. LKMs are typically used to add support for new hardware (as device drivers ) and/or filesystems , or for adding system calls .
The Linux DTrace implementation is a loadable kernel module, which means that the kernel itself requires no modification, and thus allows DTrace to avoid CDDL vs. GPL licensing conflicts (in its source form, at least). However, once DTrace is loaded the kernel instance will be marked as tainted.
All device drivers, file systems, etc still run in kernel mode, just like in a monolithic kernel (see hybrid kernel). And how exactly are Windows's loadable kernel drivers different from LKM? The fact that Windows doesn't call them "kernel modules" doesn't mean it doesn't have a similar concept.
LKM or lkm may refer to: 7, Lok Kalyan Marg, the official residence and principal workplace of the Prime Minister of India "Liver Kidney Microsomal", the target of an Anti-LKM antibody; LKM Unia Leszno, a Polish motorcycle racing team; Loadable kernel module, an object code file used to extend the kernel of a computer's operating system
A NetWare Loadable Module [1] [2] [3] (NLM) is a loadable kernel module (a binary code module) that can be loaded into Novell's NetWare operating system. NLMs can implement hardware drivers, server functions (e.g. clustering), applications (e.g. GroupWise ), system libraries or utilities.
However, after Oracle announced the discontinuation of OpenSolaris, plans were made to fork the final version of the Solaris ON kernel, [a] allowing Illumos to evolve into a kernel of its own. [13] As of 2010 [update] , efforts focused on libc, the NFS lock manager, the crypto module, and many device drivers, to create a Solaris-like OS with no ...
The Oracle Cluster File System (OCFS, in its second version OCFS2) is a shared disk file system developed by Oracle Corporation and released under the GNU General Public License. The first version of OCFS was developed with the main focus to accommodate Oracle's database management system that used cluster computing .
This disallows a root user to load arbitrary code via kexec and execute it, complementing the UEFI secure boot and in-kernel security mechanisms for ensuring that only signed Linux kernel modules can be inserted into the running kernel. [4] [5] [6] Kexec is used by LinuxBoot to boot the main kernel from the Linux kernel located in the firmware.
