A simple system call that adds 2 numbers together then returns the result to a variable in the userspace.
Adds a system call that adds 2 numbers together and stores them in an int variable that resides in the userspace. Place the following kernel files in the appropriate paths listed below:
arch/x86/kernel/simple_add.c
arch/x86/kernel/Makefile
arch/x86/syscalls/syscall_64.tbl
includes/linux/syscalls.h
Takes the numbers 4 and 5 and sends them to the simple add syscall which should result in 9
syscall.c
(compile and run with gcc syscall.c -o syscall; ./syscall)
/var/log/syslog
