This directory contains the system call definitions for Fuchsia‘s kernel, Zircon. They are currently updated manually, but we hope that will change Real Soon Now. When/if it does, we’ll update this file.
The .fidl files in the vDSO directory describe Zircon's system calls in FIDL, and in the comments there are English and C++ descriptions. For every FIDL file, there should be a corresponding .txt file in this directory that describes the system calls using Syzkaller's syzlang language.
