The compose pinned 172.31.0.0/24 with a per-container ipv4_address, so two
concurrent runs of this suite asked docker for the same address space and the
second failed with a pool-overlap error. Request no subnet instead and let
docker assign one from the daemon pool, which leaves nothing for two runs to
contend for. Peers now address each other by the docker hostname the compose
already sets (host-a through host-f) rather than by literal IP, and docker's
embedded DNS is per-network, so the same hostname in two runs resolves inside
each run's own subnet.
The generated config directory moves under the run suffix in the same change,
because it has to: the generator does rm -rf on it, so a shared directory means
one run deletes the fixtures another is still using, which fails silently rather
than loudly at bring-up. Scoping it requires the generator output path, all five
bind-mount sources per service, and the gitignore entry together; scoping only
the generator leaves the compose reading the unscoped path.
The floating subnet removes one of the two obstacles to running this suite
twice at once, not both: the compose project name is still fixed, and nothing
scopes it for this suite. Recorded at the site so the comment does not claim
more than the change delivers.
Implement TCP Wrappers-style peer access control using
/etc/fips/peers.allow and /etc/fips/peers.deny files. Evaluation
order: allow overrides deny, default permit when no files exist.
Three enforcement points: outbound connect (before dialing), inbound
handshake (msg1 receipt, after restart/rekey classification), and
outbound handshake completion (msg2, before peer promotion). Files
support npub, hex pubkey, host alias, and ALL wildcard entries with
automatic mtime-based reload.
Adds fipsctl acl show query, 954-line acl module with unit tests,
and a 6-node Docker integration harness (testing/acl-allowlist/)
exercising insider, outsider, and allowed-remote scenarios. CI
matrix entry included.
Closes#50
