Become a Linux Kernel Hacker and Write Your Own Module

Posted by Soulskill on from the or-else dept.

M-Saunders (706738) writes "It might sound daunting, but kernel hacking isn't a mysterious black art reserved for the geekiest of programmers. With a bit of background knowledge, anyone with a grounding in C can implement a new kernel module and understand how the kernel works internally. Linux Voice explains how to write a module that creates a new device node, /dev/reverse, that reverses a string when it's written to it. Sure, it's not the most practical example in the world, but it's a good starting point for your own projects, and gives you an insight into how it all fits together."

    Well yes, any C developer (already a minority in the umbrella of 'programmers' these days) can write code for the kernel, but just because one can write software for the kernel doesn't mean they can write anything meaningful to be done in kernel space vs. anywhere else. If you're expecting a slew of new driver hackers reverse engineering chipsets, and implementing better drivers, testing all corner cases (because dev's LOVE testing) I think you're barking up a very small tree, but all the luck to you, becase what's good for Linux is good for me, you, us all.
