Single-file LKM concepts
- Base - Simple, but full example on a generic LKM implementation. No real functionality, but an excellent starting point.
- Keylogger - LKM Keylogger that uses a character device to retrieve the data logged.
- List-Dir - List userland directories from within the Kernel using Linux Dirent structures.
- Packet Stealing - LKM that forces a DoS on TCP packets by stealing them at the Netfilter prerouting hook.
- Get-Arch - LKM to retrieve the CPU's architecture based on whether x86_64 Long-Mode is present or not.
- Kernel Lists - Demonstration of how to use Linux's linked list API to update an old list when compared with a new one.
Create a new directory with a descriptive name of your example and fill it with a single C file and Makefile.
