The swarm controller (port 8770) exposed 9 routes with zero app-layer
auth, and swarmctl --tls defaulted off — anyone able to reach the port
could enroll workers (minting CA-signed certs + private keys), deploy,
or tear down the fleet. Two fail-closed layers:
- require_operator_cert gates every operator route (enroll/deploy/
teardown/hosts/check/deckies). When mTLS is on, the peer cert's CN
must be an operator identity (decnet-master/swarmctl); worker and
updater@* certs are rejected. Plaintext loopback (single-host master)
is accepted as the local operator — the docker.sock boundary.
- swarmctl refuses to bind a routable interface without --tls, so a
network-exposed plaintext control plane can never start.
/heartbeat keeps its worker fingerprint pinning. Closes the two ASVS
criticals (control-plane no-auth, unauthenticated cert minting).
Replaces LICENSE (GPLv3 -> AGPLv3) and prepends
`SPDX-License-Identifier: AGPL-3.0-or-later` to every source file
across decnet/, decnet_web/, tests/, scripts/, and tools/.
Rationale: closes the GPLv3 ASP loophole so any party operating a
modified DECNET as a network service must offer their modified
source. Personal copyright (Samuel Paschuan) + inbound=outbound
contributions make a future unilateral relicense infeasible.
