clawbot	234c5eac60	Serve Prometheus metrics behind SWWAF_METRICS_TOKEN (closes #23) ... GET /_smallwebwaf/metrics answers in the Prometheus text format for a request carrying SWWAF_METRICS_TOKEN, 401 without it and 404 while it is unset. Every request under /_smallwebwaf/ but the health check now goes through the checks and is answered where it would be forwarded, 404 for any path but the metrics, so none reaches the app. In the client's history a 401 counts as refused, the metrics and the 404s as neither. SWWAF_METRICS_TOP_N bounds the series by country, the rest counted as other. Deviation: go.mod and go.sum written by hand, as go runs only through make. Deviation: no metrics yet for state files read again after an edit or edits set aside; that work is not merged. Model: opus-5-5	2026-10-06 11:40:27 +02:00
clawbot	df2c5042d2	Keep the bans, the clients and GeoJS's answers in state files (closes #17) ... smallwebwaf now copies its state to bans.json, clients.json and lookups.json in SWWAF_STATE_DIR, as "Persistent state" in SPEC.md describes, and reads them back at start, so a restart lifts no ban and gives no client a fresh allowance. Each client gains a history, and a ban's notes count the netblock's requests. bans.json is written SWWAF_STATE_WRITE_DELAY after a ban, and every file every SWWAF_STATE_COUNTER_INTERVAL and at the stop. A ban read back is masked to its netblock and refuses every client in it. A file that does not parse, an unknown version, an entry without a field it needs, or an unwritable directory stops the start. Deviation: no AS number or name, and no ban cause, reason or lifting yet. Model: opus-5-5	2026-10-06 08:31:52 +02:00
clawbot	0750879e58	Country allow and deny lists, looked up through GeoJS (closes #44) ... SWWAF_DENIED_COUNTRIES and SWWAF_EXCLUSIVELY_ALLOWED_COUNTRIES refuse a request with 403 before its body is read or rate-limited, logged as country_denied. internal/lookup asks GeoJS only while a list is set, 200 clients per request, one at a time, keeping answers 7 days. Failures, a redirect or an answer leaving an address out included, are logged without addresses; GeoJS is then left alone a second, doubling to five minutes. Private, loopback and link-local clients are never sent. Deviation, per the issue: no SWWAF_LOOKUP_SOURCE or SWWAF_LOOKUP_TIMEOUT; 403, not SWWAF_BAN_RESPONSE. Deviation: GeoJS's country endpoint, not geo.json. Judgement call: an IPv6 /64 is asked about by its first address; at most 10,000 clients wait. Judgement call: config.go lists the ISO 3166-1 codes; no widely used library holds them. Model: opus-5-5	2026-10-04 08:29:41 +02:00
