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 — af_packet2 (CVE-2020-14386)
Vulnerability
CVE-2020-14386 — AF_PACKET tpacket_rcv VLAN integer underflow
(maclen = skb_network_offset(skb) when network header precedes
maclen) → 8-byte heap OOB write at the start of the next slab object.
Research credit
Discovered and disclosed by Or Cohen (Palo Alto Networks), September 2020.
Original advisory: https://unit42.paloaltonetworks.com/cve-2020-14386/
Upstream fix: mainline 5.9 / stable 5.8.7 (Sept 2020). Branch backports: 5.8.7 / 5.7.16 / 5.4.62 / 4.19.143 / 4.14.197 / 4.9.235.
SKELETONKEY role
Sibling of CVE-2017-7308; same subsystem, different code path.
Fires the underflow via tp_reserve + sendmmsg sk_buff spray.
PRIMITIVE-DEMO scope by default (no cred overwrite). --full-chain
attempts the Or-Cohen-style sk_buff data-pointer hijack through
the shared finisher.
Shares the skeletonkey-af-packet auditd key with the CVE-2017-7308
module so detection signatures dedupe cleanly.
