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 — entrybleed
Vulnerability
CVE-2023-0458 — KPTI prefetchnta timing side-channel leaks the
kernel base address (KASLR bypass).
Research credit
Discovered by Will Findlay. Formally presented at USENIX Security '23:
"EntryBleed: A Universal KASLR Bypass against KPTI on Linux" Bert Jan Schijf, Cristiano Giuffrida — USENIX Security 2023
Mainline status: no canonical patch — partial mitigations only.
SKELETONKEY role
This is a stage-1 leak primitive, not a standalone LPE. Other
modules can call entrybleed_leak_kbase_lib() to obtain a KASLR
slide and feed it to the offset resolver in core/offsets.c. x86_64
only; the entry_SYSCALL_64 slot offset is configurable via the
SKELETONKEY_ENTRYBLEED_OFFSET env var.
