/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
On Fedora, you can just do:
makeOn Arch, just install uwurandom-git-dkms from the AUR! >/////<
On other distros, you may need to adjust the include paths in the Makefile depending on where your kernel headers are located (I think it's /usr/src/linux-headers-\`uname -r` on Ubuntu and /usr/lib/modules/`uname -r`/build on Arch but don't quote me on that). After that you should be able to make as usual.
Usage is also easy! >w<
sudo insmod uwurandom.koAfterwards, you can just:
cat /dev/uwurandomand witness its sheer glory with your own eyes.
