/dev/urandom is made out of cold hard math. Instead, consider using /dev/uwurandom, which generates data through a tiny catgirl furiously typing away utter nonsense inside your computer.
Disclaimer: I am very bad at C. While I've tested this myself and haven't managed to cause a kernel panic, this is not production-quality code. Use at your own risk.
Compilation is easy :3
First up, you'll need to install kernel headers for whichever kernel version you've installed.
On Ubuntu or Debian (assuming your kernel is already up-to-date):
sudo apt-get install linux-headers-genericOn Fedora:
sudo dnf install kernel-develOn Arch:
sudo pacman -S linux-headers(or linux-lts-headers if you're using the linux-lts kernel)
Once you've installed the kernel headers, you should be able to simply run make to build the kernel module:
makeUsage is also easy! >w< To insert the kernel module, just run:
sudo insmod uwurandom.koWhen the module is loaded, it automatically sets up the /dev/uwurandom device, so you can do:
cat /dev/uwurandomand witness its sheer glory with your own eyes.
If things are a bit too silly and you want to un-load the kernel module, run:
sudo rmmod uwurandom
