Convert assert_log_contains from a one-shot grep snapshot into a
bounded poll that retries until the pattern appears or the timeout
elapses (default 15s). Same wait-with-timeout shape as
wait_for_peers_exact above it in the file.
The pre-existing flake on next-branch CI is structural: under XX
handshake, the cross-connection tie-breaker selects which side
reaches its ACL-check point first. When container-a wins the
tie-breaker on the first attempt against c and d, only the
outbound-handshake-context rejection fires immediately, and the
inbound-handshake-context rejection only emits on a later retry
when c or d's msg1 lands while a has no pending outbound. On one
2026-05-14 run the inbound rejection appeared 63ms after the test
had given up. The race window is small but real.
Polling the log instead of one-shot reading absorbs the
millisecond-to-second variance without slowing the success path
(the helper returns as soon as the pattern appears).
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.
