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.
Each module now exposes an opt-in full-chain root-pop via --full-chain:
default --exploit behavior is unchanged (primitive-only, returns
EXPLOIT_FAIL). With --full-chain, after primitive lands, modules call
iamroot_finisher_modprobe_path() via a module-specific arb_write_fn
that re-uses the same trigger + slab groom to write a userspace
payload path into modprobe_path[], then exec a setuid bash dropped
by the kernel-invoked modprobe.
netfilter_xtcompat (+239): msg_msg m_list_next stride-seed FALLBACK
af_packet (+316): sk_buff data-pointer stride-seed FALLBACK
af_packet2 (+156): tp_reserve underflow + skb spray, LAST RESORT
nf_tables (+275): forged pipapo_elem with kaddr value-ptr
(Notselwyn offset 0x10), FALLBACK
cls_route4 (+251): msg_msg refill of UAF'd filter, FALLBACK
fuse_legacy (+291): m_ts overflow + MSG_COPY sanity gate,
FALLBACK (one of two modules with a real
post-write sanity check)
stackrot (+233): race-driver budget extended 3s → 30s when
--full-chain; honest <1% race-win/run
All seven honor verified-vs-claimed: arb_write_fn returns 0 for
"trigger structurally fired"; the shared finisher's setuid-bash
sentinel poll is the empirical arbiter. EXPLOIT_OK only when the
sentinel materializes within 3s of the modprobe_path trigger.
Build clean on Debian 6.12.86 (kctf-mgr); all 7 modules refuse
cleanly on both default and --full-chain paths via the existing
patched-kernel detect gate (short-circuits before the new branch).
