Hi! I'm new here and i what to introduce myself i'm teacher in a University in the course Operation Systems. During the course the students learn some Operatyng Systems concepts, specially everything relating to the Kernel. As a practice task, they also have to use C to make a program with some Kernel functionalities. This year this task consists on programming a File System (I chose FAT32 since I thought it was the easiest one to implement) using FUSE and simulating a Hard Disk and a RAID behavior. Since I'm not a Kernel expert I'm looking for some advice and ideas. The aim of the practice task I'm creating is to help the students make a program that simulates the behavior and functionalities of a Kernel (such as a File System, Memory Administrator, Planner, etc.), but at the same I would like those programs to really interact with the Kernel, being not only ideal simulation cases (like FUSE). But, as I said, I don't know that much to have a good idea of what can I use to make the most from the Kernel in the task. I could really use some ideas! Some of the things I have in mind: - Use netlinks - Build a kernel module - I'm also interested in the /dev/mem ¡Thanks a lot in advance!
