Improvements compared to main project :
- Building is done in a container : no compilation problems on newer kernels
- Added small userspace programs to start playing.
NOTE: you don't need to interact with this repo in the course of interacting with pwn.college. The kernel challenges can be solved in the infrastructure; this is just here as a way to reproduce the infrastructure locally.
First, run scripts/setup.sh : this will build a docker image capable of building older kernels.
Building the kernel, busybox, demo modules, filesystem (initramfs) and userspace programs :
$ make kernel
$ make busybox
$ make modules
$ make fs
$ make userspace
Running the kernel: (this will build everything automatically for you)
$ make run
All modules will be in /, ready to be insmoded, and the host's userspace build directory will be mounted as /home/ctf in the guest.
