-# Putting rickrolling in kernel space
-
-Kernelroll is a linux kernel module for advanced rickrolling.
-
-It works by patching the open() system call to open a specified music file
-instead of other music files. Currently, it only checks if the file extension
-"mp3" is present and calls the original open() with the supplied path
-instead.
-
-WARNING: There is probably a performance penalty and your kernel might crash
-at a very inappropriate time and cause data loss! You are responsible for
-the code you load into your kernel!
-
-But most probably, it will be alright! ;)
-
-# Installation
-
-You need the address of sys_call_table in your kernel. Use
-
- $ grep sys_call_table /boot/System.map-3.0.0-1-amd64
- ffffffff81400300 R sys_call_table
-
-on the respective System.map of your kernel to find out the address
-
-Now fire up kernelroll.c and add yours:
-
- void **sys_call_table = (void **)0xffffffff81400300;
-
-This will probably be simplified in the future, but as sys_call_table isn't
-exported anymore in 2.6 kernels, we have to use some tricks.
-
-Compile with:
-
- $ make
-
-Load with:
-
- $ insmod kernelroll.ko rollfile=/path/to/rickroll.mp3
-
-Fire up a music player of your choice, play a song and consider yourself
-kernelrolled. ;)
