Extend the fipsctl control query interface with visibility into internal
state critical for protocol security auditing, mesh troubleshooting, and
operational monitoring.
New command:
fipsctl show identity-cache
Lists every node identity cached by the daemon (learned from DNS
resolution, peer handshakes, sessions, and static config). Shows
npub, IPv6 address, display name, and LRU age alongside the
configured cache capacity.
Extended queries:
show peers — Noise session counters (send_counter, highest received
counter) for rekey urgency assessment. Per-peer replay suppression
and consecutive decrypt failure counts for active attack detection.
Session index visibility for hijack analysis. Rekey lifecycle
state (in_progress, draining, K-bit epoch).
show sessions — Handshake resend count during establishment for
connectivity debugging. Rekey and session health fields
(session_start, K-bit, coords warmup, drain state) when
established.
show cache — Individual coordinate cache entries with tree
coordinates, depth, path MTU, and age. Enables route-level
debugging by showing exactly which destinations have cached
routes and via what tree path. Renames the top-level count
field from "entries" to "count" for clarity.
show routing — Pending discovery lookups expanded from count to
per-target detail (attempt number, age, last sent). Pending
TUN packet queue depth for backpressure visibility. Connection
retry state per peer (retry count, next attempt, auto-reconnect
flag).
Updates fipstop to match the revised show_cache and show_routing
response schemas. Updates README monitoring section with the complete
fipsctl command list.
