From 67d091dd378d37b30d95ebe6b25dd0fbac0723f2 Mon Sep 17 00:00:00 2001 From: KaraZajac Date: Sat, 23 May 2026 15:46:14 -0400 Subject: [PATCH] =?UTF-8?q?verified=5Fon=20table=20=E2=80=94=205=20modules?= =?UTF-8?q?=20empirically=20confirmed=20in=20real=20VMs?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the loop opened by tools/verify-vm/: every JSON verification record now persists into docs/VERIFICATIONS.jsonl, gets folded into the embedded core/verifications.c lookup table, and surfaces in --list / --module-info / --explain / --scan --json. New: docs/VERIFICATIONS.jsonl Append-only store. One JSON record per verify.sh run. Records carry module, ISO timestamp, host_kernel, host_distro, vm_box, expected vs actual verdict, and match status. 6 lines today (5 unique after dedup; the extra is dirty_pipe's pre-correction MISMATCH that surfaced the silent-backport finding — kept in the JSONL for history, deduped out of the C table). New: tools/refresh-verifications.py Parses VERIFICATIONS.jsonl, dedupes to latest per (module, vm_box, host_kernel), generates core/verifications.c with a static array + lookup functions: verifications_for_module(name, &count_out) verifications_module_has_match(name) --check mode for CI drift detection. New: core/verifications.{h,c} Embedded record table. Lookup is O(corpus); we have <50 records. skeletonkey.c surfacing: - --list: new 'VFY' column shows ✓ for modules with >=1 'match' record. Five modules show ✓ today (pwnkit, cgroup_release_agent, netfilter_xtcompat, fuse_legacy, dirty_pipe). - --module-info: new '--- verified on ---' section enumerates every record with date / distro / kernel / vm_box / status. Modules with zero records get a 'run tools/verify-vm/verify.sh ' hint. - --explain: new 'VERIFIED ON' section in the operator briefing. - --scan --json / --module-info --json: 'verified_on' array of record objects per module. Verification records baked in: pwnkit Ubuntu 20.04.6 LTS 5.4.0-169 match (polkit 0.105) cgroup_release_agent Debian 11 (bullseye) 5.10.0-27 match netfilter_xtcompat Debian 11 (bullseye) 5.10.0-27 match fuse_legacy Debian 11 (bullseye) 5.10.0-27 match dirty_pipe Ubuntu 22.04.3 LTS 5.15.0-91 match (OK; silent backport) The dirty_pipe record is particularly informative: stock Ubuntu 22.04 ships 5.15.0-91-generic. Our version-only kernel_range check would say VULNERABLE (5.15.0 < 5.15.25 backport in our table). The --active probe writes a sentinel via the dirty_pipe primitive then re-reads; on this host the primitive is blocked → sentinel doesn't land → verdict OK. Ubuntu silently backports CVE fixes into the patch level (-91 here) without bumping uname's X.Y.Z. The targets.yaml entry was updated from 'expect: VULNERABLE' to 'expect: OK' to reflect what the active probe definitively determined; the original VULNERABLE expectation is preserved in the JSONL history as a demonstration of why we ship an active-probe path at all (this is the verified-vs- claimed bar in action). Plumbing fixes that landed in the same loop: - core/nft_compat.h — conditional defines for newer-kernel nft uapi constants (NFT_CHAIN_HW_OFFLOAD, NFTA_VERDICT_CHAIN_ID, etc.) that aren't in Ubuntu 20.04's pre-5.5 linux-libc-dev. Without this, nft_* modules failed to compile inside the verifier guest. Included from each nft module after . - tools/verify-vm/Vagrantfile — wrap config in c.vm.define so each module gets its own tracked machine; disable Parallels Tools auto-install (fails on older guest kernels); translate underscores in guest hostname to hyphens (RFC 952). - tools/verify-vm/verify.sh — explicit 'vagrant rsync' before 'vagrant provision build-and-verify' (vagrant only auto-rsyncs on fresh up, not on already-running VMs); fix verdict-grep regex to tolerate Vagrant's 'skk-:' line prefix + '|| true' so a grep miss doesn't trigger set-e+pipefail; append JSON record to docs/VERIFICATIONS.jsonl on every run. - tools/verify-vm/targets.yaml — dirty_pipe retargeted from ubuntu2004 + pinned 5.13.0-19 (no longer in 20.04's apt) to ubuntu2204 stock 5.15.0-91 (apt-installable + exercises the active-probe-overrides-version-check path). What's next for the verifier: - Mainline kernel.ubuntu.com integration so we can actually pin arbitrary historical kernels (currently the pin path only works with apt-installable packages). - Sweep the remaining ~18 verifiable modules and accumulate records. - Per-module verified_on counts in --explain header. --- Makefile | 2 +- core/verifications.c | 99 +++++++++++++++++++ core/verifications.h | 52 ++++++++++ docs/VERIFICATIONS.jsonl | 6 ++ skeletonkey.c | 80 ++++++++++++++- tools/refresh-verifications.py | 174 +++++++++++++++++++++++++++++++++ tools/verify-vm/Vagrantfile | 6 +- tools/verify-vm/targets.yaml | 10 +- tools/verify-vm/verify.sh | 23 +++-- 9 files changed, 428 insertions(+), 24 deletions(-) create mode 100644 core/verifications.c create mode 100644 core/verifications.h create mode 100644 docs/VERIFICATIONS.jsonl create mode 100755 tools/refresh-verifications.py diff --git a/Makefile b/Makefile index eac837c..7f5939c 100644 --- a/Makefile +++ b/Makefile @@ -21,7 +21,7 @@ BIN := skeletonkey # core/ CORE_SRCS := core/registry.c core/kernel_range.c core/offsets.c core/finisher.c \ - core/host.c core/cve_metadata.c + core/host.c core/cve_metadata.c core/verifications.c CORE_OBJS := $(patsubst %.c,$(BUILD)/%.o,$(CORE_SRCS)) # Register-every-module helper.
