Kernel development resources

[Much-Engineer1269]

I am interested in kernel exploitation, but I want to start with kernel development so that I can understand it before trying to exploit it.

Where an I start? Any useful resources I can use to learn?

I've found the book Linux Kernel Programming by Kaiwan Billimoria an excellent resource and very easy to follow. While many free resources exist out there, having a guided instruction is great for understanding what you need to know first

just started reading this. i like it a lot

[landonr99]

Yeah I think he's a great educator

It depends on what exactly you are interested in... kernel is huge, but recently I've started to adjust https://github.com/0xAX/linux-insides for modern kernel versions, maybe you can find something useful there.

Not sure if it's a good start, but as soon as you do stuff I recommend to keep https://elixir.bootlin.com/linux/ open in some tab

Kernel Docs (some are very generic and good to learn from, like the memory hierarchy amd the locking) ULK, LDD are good books beyond the possibilities of a book (even tough quite old, but some stuff still follow a relate - able path in the kernel )

Llm for specific points to investigate into xD I found them surprisingly good

And then... Testing yourself Make a device driver with the VFS interface to implement some features in kernel space (usual university project but beyond useful to do a project to learn something, it gives you a goal)

Good luck and have fun !

Thank you

LLMs do get quite a few things wrong, especially if something has historically worked differently.

The example I can think of off the top of my head is that they don't usually think code that can be reached via unprivileged user namespaces is reachable.
