• Gathering Linux Syscall Numbers in a C Table

  There is an existing project that tracks and gather syscalls in the linux kernel, for all ABIs: https://github.com/mebeim/systrack . The author maintains a table here, which is incredibly useful: https://syscalls.mebeim.net/?table=x86/64/x64/latest

• A Linux kernel syscall implementation tracker

  Thank you very much :). I am using static analysis of kernel images (vmlinux ELF) that are built with debug information. Each table you see was extracted from a kernel built by my tool, Systrack, that configures and builds kernels configured to have all the syscalls available. The code is heavily commented and available on GitHub if you are interested: https://github.com/mebeim/systrack

  I realized soon in the process that simply looking at kernel sources was not enough to extract everything accurately, also I wanted this to be a tool to extract syscalls actually implemented from a given kernel image, so that's what it does.

  Your approach should be fine, that is what any other language does basically: rely on uapi headers provided by the kernel (just beware that some may be generated at build time inside e.g. include/asm/generated/xxx). Add a generic function that takes an arbitrary syscall number and an arbitrary amount of args to make raw syscalls for the weird ones and you should be good. After all, even in the C library headers some of the "weird" syscalls aren't present sometimes.
