Every kernel-LPE module that uses Linux-only headers (splice, posix_fadvise,
linux/netlink.h, sys/ptrace.h, etc.) now follows the same #ifdef __linux__
pattern the new modules already used: Linux body in the ifdef, stub
detect/exploit/cleanup returning SKELETONKEY_PRECOND_FAIL on non-Linux,
platform-neutral rule strings + module struct + register fn left outside.
14 modules wrapped:
dirty_pipe (already done above), af_packet, af_packet2,
cgroup_release_agent, cls_route4, dirty_cow, fuse_legacy,
netfilter_xtcompat, nf_tables, nft_fwd_dup, nft_payload,
overlayfs, overlayfs_setuid, ptrace_traceme.
Several modules previously had ad-hoc partial stubs (af_packet2 faked
SIOCSIFFLAGS/MAP_LOCKED, netfilter_xtcompat faked sysv-msg syscalls,
the nft_* modules had 3 partial __linux__ islands each, fuse_legacy /
nf_tables had inner-only ifdef blocks) — all replaced with the uniform
outer-wrap shape from dirty_pipe / dirtydecrypt / fragnesia / pack2theroot.
Where a module includes core/kernel_range.h, core/finisher.h, or
core/offsets.h, those are now inside the ifdef block as well — silences
clangd's "unused-includes" LSP warning on macOS while keeping them
present for the real Linux build.
No exploit logic, constant, struct, shellcode byte, or rule string was
modified — only include placement and ifdef markers.
Build verification:
macOS (local): make clean && make → Mach-O x86_64, 31 modules
registered, --scan reports each Linux-only module as
"Linux-only module — not applicable here".
Linux (docker gcc:latest + libglib2.0-dev): make clean && make →
ELF 64-bit, 31 modules. Exploit code paths unchanged.
The README has been claiming "each module credits the original CVE
reporter and PoC author in its NOTICE.md" since v0.1.0, but only
copy_fail_family actually shipped one. Fixed.
modules/<name>/NOTICE.md (×19 new + 1 existing): per-module
research credit covering CVE ID, discoverer, original advisory
URL where public, upstream fix commit, IAMROOT's role.
iamroot.c: new --dump-offsets subcommand. Resolves kernel offsets
via the existing core/offsets.c four-source chain (env →
/proc/kallsyms → /boot/System.map → embedded table), then emits
a ready-to-paste C struct entry for kernel_table[]. Run once
as root on a target kernel build; upstream via PR. Eliminates
fabricating offsets — every shipped entry traces back to a
`iamroot --dump-offsets` invocation on a real kernel.
docs/OFFSETS.md: documents the --dump-offsets workflow.
CVES.md: notes the NOTICE.md convention + offset dump tool.
iamroot.c: bump IAMROOT_VERSION 0.3.0 → 0.3.1.
Pre-scaffolding for the next batch (CVE-2023-32233, CVE-2023-4622,
CVE-2022-25636, CVE-2023-0179). Each module ships as a 21-line
stub returning PRECOND_FAIL; parallel agents fill in the real
detect/exploit/--full-chain implementations.
This commit keeps registry.h / iamroot.c / Makefile in one place
so the 4 parallel agents don't collide on shared-file edits — they
each own a single iamroot_modules.c.
Build clean on Debian 6.12.86; --list shows all 24 modules
including the 4 new stubs.
