Drivers and Interrupts is a 42 Linux Kernel Module Project written in C where you have to code a Linux Kernel keylogger.

This keylogger is a Linux Kernel module and it must be able to capture a key being pressed and released. The module must then create a misc device character file, which when read prints out in a log the keys that it captured. The logs are also saved the the kernel logs.


On exit, the module will print the number of keys captured.

To build, install and run the module:
```sh
make install
```

To build, install and run the module when a keyboard is plugged in:
```sh
make rule_install
```

> Only compatable on systems where udev is installed.
