Kernmodules
Kernel modules are pieces of code that can be dynamically loaded into an operating system kernel to extend its capabilities without rebooting the system. In Linux, loadable kernel modules (LKMs) enable features such as device drivers, filesystem support, and network protocol handlers. Modules run with the same privileges as the kernel and can be inserted, removed, or configured at runtime.
A module provides initialization and cleanup functions declared with module_init and module_exit, and exports symbols that
The kernel loads a module using tools such as modprobe or insmod. Modprobe handles dependencies by loading
Loading and unloading must consider dependencies and in-use references. Some systems enforce module signing and restrictions;
Development and lifecycle: Module authors follow kernel coding standards and APIs, use exported interfaces, and manage
