About

Linux Syscalls is an open, multilingual reference for every Linux system call: cross-architecture numbers (x86, x64, ARM64), kernel-version history, seccomp profile relevance, eBPF and strace guidance, and rootkit / hooking notes.

Data sources

Architecture numbers are synchronised from the upstream Linux kernel tree at a pinned tag (arch/x86/entry/syscalls/syscall_64.tbl, syscall_32.tbl, and include/uapi/asm-generic/unistd.h). Prose is written from scratch and reviewed against the man-pages project, but not copied verbatim.
