Breaking change. Tool name, binary name, function/type names,
constant names, env vars, header guards, file paths, and GitHub
repo URL all rebrand IAMROOT → SKELETONKEY.
Changes:
- All "IAMROOT" → "SKELETONKEY" (constants, env vars, enum
values, docs, comments)
- All "iamroot" → "skeletonkey" (functions, types, paths, CLI)
- iamroot.c → skeletonkey.c
- modules/*/iamroot_modules.{c,h} → modules/*/skeletonkey_modules.{c,h}
- tools/iamroot-fleet-scan.sh → tools/skeletonkey-fleet-scan.sh
- Binary "iamroot" → "skeletonkey"
- GitHub URL KaraZajac/IAMROOT → KaraZajac/SKELETONKEY
- .gitignore now expects build output named "skeletonkey"
- /tmp/iamroot-* tmpfiles → /tmp/skeletonkey-*
- Env vars IAMROOT_MODPROBE_PATH etc. → SKELETONKEY_*
New ASCII skeleton-key banner (horizontal key icon + ANSI Shadow
SKELETONKEY block letters) replaces the IAMROOT banner in
skeletonkey.c and README.md.
VERSION: 0.3.1 → 0.4.0 (breaking).
Build clean on Debian 6.12.86. `skeletonkey --version` → 0.4.0.
All 24 modules still register; no functional code changes — pure
rename + banner refresh.

NOTICE — dirty_pipe
Vulnerability
CVE-2022-0847 — pipe PIPE_BUF_FLAG_CAN_MERGE flag inheritance allows
arbitrary file write into the page cache.
Research credit
Discovered and disclosed by Max Kellermann (CM4all GmbH), March 2022.
Original advisory: https://dirtypipe.cm4all.com/
Upstream fix: mainline 5.17 (commit 9d2231c5d74e, Feb 2022).
SKELETONKEY role
This module bundles the canonical splice-into-pipe primitive that
writes UID=0 into /etc/passwd's page cache, then drops a root shell
via su. Detection covers the splice() syscall against sensitive
files and non-root modifications to passwd/shadow.
