clawbot	7f472c40e2	Rule files, and bans for a clear sign of attack (closes #24) ... Every *.rules file in SWWAF_RULES_DIR is read at start and on each change, and 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 clear sign of attack. path, query and uri are matched as the request line sent them. bans.json gains each ban's cause, and ban notes count earlier bans by 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 14:33:26 +00:00
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	d4f90dba37	The image apps build FROM, with its health check (closes #45) ... The Dockerfile's last stage is now the image of "Deployment" in SPEC.md: Ubuntu 26.04 with ca-certificates, nix-bin and runit from a dated snapshot whose InRelease files are checked by hash, nixpkgs from its release file checked by SHA-256, runsvinit built at a fixed commit, and smallwebwaf as a runit service. smallwebwaf answers /_smallwebwaf/healthz, and `smallwebwaf healthcheck`, which takes no further argument, is the image's HEALTHCHECK. script/example-app builds an app on the image and checks it end to end. The Nix profile comes last on the PATH: first, busybox from nixpkgs replaced runit's own runsvdir and sv. SPEC.md is corrected to match what was built. Model: opus-5-5	2026-10-04 10:05:30 +02:00
