clawbot	d5a6c74e4e	Bans an admin makes or lifts: the admin cause, a reason, lifted bans kept (closes #86) ... A bans.json entry without a cause gets the cause admin, written back so. Bans whose cause is admin are never dropped and do not count toward SWWAF_MAX_BANS, so setting a ban's cause to admin keeps it. Bans smallwebwaf makes get a reason: the limit broken or the rule matched. A lifted ban refuses nothing, is kept, and makes no later ban longer. smallwebwaf_bans_made_total counts admin bans an edit adds while running; earlier_bans counts admin in place of without_cause. Judgement call: lifted lifts at once, whatever time it gives. Judgement call: a lifted ban still counts in earlier_bans. Known gap: a ban dropped from behind an admin's ban on its netblock leaves that netblock's later earlier_bans. Model: opus-5-5	2026-10-06 20:57:13 +00:00
clawbot	0797e5def2	Send every log line to a syslog server as well (closes #28) ... With SWWAF_LOG_REMOTE_URL set (syslog+udp, syslog+tcp or syslog+tls), every line on stdout is also sent as the message of an RFC 5424 record, octet-counted over TCP and TLS, from a bounded buffer that drops its oldest line when full, so a slow or unreachable server holds up nothing. Failed connections are retried with backoff; lines sent, dropped and waiting are metrics. At a stop the lines still waiting get at most two seconds. SWWAF_LOG_REMOTE_APP_NAME defaults to SWWAF_INSTANCE_NAME; while sending, an app name RFC 5424 does not allow stops the start. Standard library only: log/syslog writes only the older format.

clawbot	e77dfb6891	Rule files, and bans for a clear sign of attack (closes #24) ... Every *.rules file in SWWAF_RULES_DIR not named with a leading dot is read at start, and again 2 seconds after the directory's last change. Each request is checked against the rules after the rate limits: log notes a match, block refuses with 403, ban refuses and bans the netblock for SWWAF_ATTACK_BAN_DURATION, made permanent by its next request or attack. path, query and uri are matched as the request line sent them; header:Host and header:Transfer-Encoding are refused. Bans gain a cause. The image ships 00-default.rules. Judgement call: a header sent twice is matched with its values joined by ", ". Judgement call: SWWAF_MAX_BAN_DURATION does not cap a ban for an attack. Not in this unit: offences for rule matches, with the error burst. Model: opus-5-5	2026-10-06 20:38:35 +02:00
clawbot	6ec52e5b87	Take in an admin's edits of the state files while running (closes #68) ... smallwebwaf watches SWWAF_STATE_DIR with fsnotify and takes in a saved edit of a state file in place of what it held. It knows its own writes by the SHA-256 of what it last read or wrote; each write first takes in an edit made since. An edit that does not parse is renamed to <name>.bad at the next write. Each edit taken in or set aside is logged and counted. Every ban on a netblock is checked, and the next ban is worked out from the one that ended last. README.md says how to add and lift a ban. Judgement call: a broken edit is set aside at the next write, since an editor's file can be read half written. Model: opus-5-5	2026-10-06 14:18:13 +02:00
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
