rustix 1.1.4 provides memory-safe and I/O-safe wrappers over POSIX/Linux/Winsock syscalls, with a libc-free linux_raw inline-asm backend. The audit read the syscall-argument safety system (typed register marshalling, error-range decoding, unsafe trait ABI contracts) and found one low-severity quality issue: per-block unsafe safety comments are inconsistent across the syscall modules.
