This is just a small project to hook syscalls in an x86_64 Linux kernel.
Most of the other kernel hooks I've seen on the public internet use an outdated mechanism to grab the syscall table - the oldest tutorials relied on sys_call_table being exported as a public symbol, and slightly newer ones had a brute-forcing approach where they would try to find the syscall table in between two different symbols. This one doesn't do anything that fancy - the load.sh script just greps /proc/kallsyms for the syscall table addresses.
make
sudo ./scripts/load.sh
