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.
Two runs on one host destroyed each other's containers, producing
mid-test "No such container" failures that look like real defects. The
automated builder runs a full local CI on the same box every few minutes,
so the machine is contended almost always and this has red-ed both a hand
run and an automated gate.
Two independent causes are fixed here. Container names were hardcoded, and
docker names are global rather than scoped by compose project, so two runs
collided on the same name; every name now takes an optional suffix that
the harness sets from the run id. And the cleanup sweep matched a label
shared by every run, so one run's teardown force-removed another's
containers; resources now also carry a per-run label and the sweep can be
narrowed to it.
A third hazard turned up that was not in the original report: the sidecar
suite passes explicit compose project names, which override the run-scoped
project and put it outside the shared prefix entirely. Its project names,
network, and derived container references are now scoped too.
Both are default-off. With the suffix unset, names render exactly as they
do today and a bare compose invocation is unchanged, which is what keeps
the hosted CI and the documentation correct. A cleanup run with no run id
still reaps everything, which is what a manual "clear the box" wants.
The literal-name sweep was not sufficient: six scripts build container
names dynamically from node labels, and two suites create their own
containers outside compose. Those are handled at their construction sites.
Verified: syntax check on all modified scripts; compose validation on
every modified file with the suffix both set and unset; and a synthetic
two-run reproduction that shows the old cleanup destroying a bystander run
and the new one leaving it alone.
Known gap: subnets are still hardcoded, so two concurrent full runs will
still collide on address-pool overlap. That fix reaches into topology
configs, chaos scenarios, diagrams and production source, so it is left
for its own change rather than half-done here.
A CI worker may preempt an in-flight ci-local.sh run (SIGTERM, then SIGKILL
after a grace period) to restart on a newer commit. For that kill to be safe,
the script must clean up after itself and never let a dying run collide with
its restart. It previously had no signal handling, shared the default compose
project name across runs, and tore down each suite only at the suite end.
- Derive a per-run id (honoring FIPS_CI_RUN_ID, else short-sha+random) and
namespace every docker resource to it: a fipsci_<run>_<suite> compose project
per suite and per parallel chaos child, and per-run image tags
(fips-test:<run>, fips-test-app:<run>) retagged to :latest only after both
builds succeed so :latest never points at a half-built image.
- Install a bounded, idempotent teardown trap on SIGTERM/SIGINT (+ EXIT): reap
parallel chaos children, then force-remove this run's docker resources via
the new ci-cleanup.sh, wrapped in timeout so a stuck down cannot wedge it.
- Exit 143 (SIGTERM) / 130 (SIGINT), distinct from 0 (pass) / 1 (failed), so a
preempting worker tells a cancelled run from a real failure.
- Add ci-cleanup.sh (also ci-local.sh --reap): force-removes leftover CI
resources by the com.corganlabs.fips-ci=1 label and the fipsci_ project
prefix, robust to however a prior run died.
- Label every per-suite docker resource so the label sweep reaps it after a
SIGKILL regardless of network name: direct docker run/network resources, the
sidecar compose services, and every per-suite compose network (acl-allowlist,
boringtun, firewall, nat, static, both tor suites, and the chaos generator
template). Parametrize the static/sidecar compose image refs so the per-run
tags are honored.
- Give each parallel chaos child a unique /24 from 10.30.x (a new --subnet
override on the sim CLI, assigned per-child in ci-local.sh) so parallel
children never collide on a shared docker subnet, and a chaos net can never
span a fixed-subnet suite (sidecar/static in 172.20.x). 10.30.x sits outside
docker's default-address-pool range, so an auto-assigned net cannot land on
it either; node IPs derive from the subnet, so no scenario config changes.
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.
