Abstract

LKM is loadable Kernel module and it is being used to extend kernel's functionality.The parameters of Kernel can be set while LKM is loaded that ease kernel modification.This paper uses system calls with modules as examples to analyze the implementation of LKM with OpenBSD,also,summarizes how to develope and test modules step by step.
