archipelagoandClaude Opus 5 40b77e392a fix(10-03): don't bless a cert minted under an untrustworthy clock
The failure fail-closed cannot catch, because generation SUCCEEDS.

This unit runs very early (DefaultDependencies=no, Before=ssh/nginx), long
before time has synced. `openssl req -x509` stamps notBefore from whatever the
clock says, so on a node with a dead RTC or a flat CMOS battery the cert can be
years out: clock ahead -> clients reject it as "not yet valid", a harder failure
than the usual self-signed warning; clock behind -> notAfter is already in the
past once time syncs. The completion marker was then set and never revisited —
a node permanently serving a cert nothing accepts.

Finding 1, reported rather than assumed: this image does NOT use
systemd-timesyncd. It installs and enables chrony, and chrony-wait.service —
the unit that is Before=time-sync.target — is not enabled. So time-sync.target
is inert here and ordering After= it would buy nothing. Enabling chrony-wait to
make it meaningful would stall boot behind NTP on a node with no network, and
these nodes are routinely offline at first boot. Not deadlocking boot outranks
cert-date elegance, so the ordering is deliberately left alone.

Fixed locally instead, in two parts:

1. Backdate notBefore by 24h so ordinary skew between node and client cannot
   invalidate a fresh cert. -not_before/-not_after arrived in OpenSSL 3.5 and
   the rootfs is debian:trixie which ships it, but the capability is PROBED,
   not assumed — guessing wrong would fail every attempt and brick the node,
   the exact outcome all of this exists to prevent. Without the flags we simply
   do not backdate and rule 2 still covers the dangerous case.

2. Refuse to bless a cert dated by a clock outside a plausible window
   (2026-01-01 .. 2056-01-01). The material stays installed so the node is
   usable and sshd comes up, but the bad dates are recorded as
   failed=cert-dates and the cert is regenerated automatically once time syncs.

Generation is now driven by need rather than by "is the marker absent", and
ConditionPathExists=! is removed from the unit so a node that already completed
can still be re-examined — skipping the unit is precisely how such a node stays
broken forever. The script exits in milliseconds when everything is fine.

Anti-spin is one condition: a date-driven regeneration happens ONLY when the
clock is currently plausible. A node whose clock is still wrong re-checks and
mints nothing.

Regression caught while writing this: driving generation purely by content made
needs_ssh() false whenever any host key existed, which would have left an
image-baked fleet-shared key in place forever — F-03 reopened. The marker check
is back in both needs_ functions and case 1 (which prestages a baked key and
asserts it was replaced) is what caught it.

Case 8 covers mint-under-wrong-clock, repair-after-sync, and both spin
directions. Controls: blessing regardless of clock reddens only case 8
(run1-BAD-DATES-NOT-RECORDED); removing the anti-spin guard reddens only case 8
(SPINNING-reminted-while-clock-still-wrong(1->2)). The second control initially
passed against a broken guard because the assertion compared certificate dates,
and a re-mint under a frozen clock produces a byte-identical notBefore — the
assertion now counts mints, which is the only thing that distinguishes "left
alone" from "regenerated again".

Not covered here: nodes already deployed from earlier ISOs never receive this
script (it is installed by the installer, not by OTA), so fleet remediation for
them remains 10-04/OTA work in core/**, which is held by other executors.

Archived ISO build recipes

These scripts built the Archipelago auto-installer ISO (bundled and unbundled variants). As of v1.7.43-alpha, ISOs are no longer part of the release deliverable. Releases ship as tarballs consumed by scripts/self-update.sh on existing nodes.

Archived here rather than deleted so they can be resurrected if ISO distribution is reintroduced.

Contents

  • build-auto-installer-iso.sh — orchestrator, bundles container images into squashfs
  • build-unbundled-iso.sh — thin wrapper that sets BUNDLE_IMAGES=0 and delegates
  • test-iso-qemu.sh — smoke-tests a built ISO under QEMU
  • scripts/convert-iso-to-disk.sh — converts an ISO to a raw disk image
  • BUILD-ISO-STATUS.md, ISO-BUILD-CHECKLIST.md — contributor guides
  • branding/isohdpfx.bin — isolinux MBR hybrid image
  • .gitea-workflows/build-iso-dev.yml — CI workflow that ran the build+smoke-test

To resurrect

  1. git mv image-recipe/_archived/* image-recipe/ (adjust paths back)
  2. Restore .gitea/workflows/build-iso-dev.yml
  3. Re-add release-process references (see scripts/create-release.sh, docs/BETA-RELEASE-CHECKLIST.md, docs/hotfix-process.md, README.md).

Why archived

The release flow is simpler and faster as tarball-only:

  • releases/vX.Y.Z-alpha/archipelago (backend binary)
  • releases/vX.Y.Z-alpha/archipelago-frontend-X.Y.Z-alpha.tar.gz (frontend + AIUI + filebrowser UI assets)
  • releases/manifest.json (pointers + changelog)

Nodes pull these via scripts/self-update.sh from either Gitea mirror. Filebrowser and AIUI remain bundled inside the frontend tarball and deployed atomically by self-update.sh.
