docs/core-rule-set.md, docs/lookup.md, docs/reputation.md and docs/bans.md restated the spec and are folded back into it and removed. The remaining docs files hold only lists: settings with their defaults and value forms, the request log's fields, the metrics, the endpoints, the state files and their contents, the rule file format and default file, the alert events and messages, the image's contents and pins, and the gitea notes. Every behaviour each of them held moves to the spec, said once. The settings groups have the same names in both files. Stale comments in internal/state and script/example-app point at the right places. Model: fable-5-1

# Admin endpoints
|
|
|
|
The endpoints under `/_smallwebwaf/`, what each takes and what each answers.
|
|
"Admin endpoints" in [`SPEC.md`](../SPEC.md) says which checks they go through
|
|
and how their tokens work.
|
|
|
|
- `GET /_smallwebwaf/healthz`: `200` and `ok`, to anyone.
|
|
- `GET /_smallwebwaf/metrics`: the metrics, for `SWWAF_METRICS_TOKEN` (see
|
|
[`metrics.md`](metrics.md)).
|
|
- `GET /_smallwebwaf/bans`: every ban held, under `bans`, each as `bans.json`
|
|
lists it. Needs `SWWAF_ADMIN_TOKEN`, as do the three below.
|
|
- `POST /_smallwebwaf/bans`: bans a netblock. The body is a JSON object of
|
|
`netblock`, `duration` and, if you like, `reason`. `netblock` is a netblock
|
|
such as `203.0.113.0/24`, or a client's address, which bans its IPv4 netblock
|
|
(`SWWAF_BAN_SCOPE_V4_PREFIX`) or its IPv6 group. `duration` is a duration such
|
|
as `1h` or `7d`, or `permanent`. A bad body is answered `400`, saying what is
|
|
wrong:
|
|
- one that is not such an object, or has another field;
|
|
- one longer than 4 KiB;
|
|
- one that names an IPv4-mapped netblock, or an address with a zone.
|
|
- `DELETE /_smallwebwaf/bans/<client>`: lifts every active ban covering the
|
|
address `<client>`. It answers `404` when none is active.
|
|
- `GET /_smallwebwaf/clients/<ip>`: what `smallwebwaf` knows of the client.
|
|
Under `client`, its counters and history as `clients.json` holds them, or
|
|
`null` when `clients.json` does not hold it. Under `bans`, every ban covering
|
|
the address, with its notes.
|
|
|
|
## Examples
|
|
|
|
With `SWWAF_ADMIN_TOKEN` set, and the token in `$TOKEN`:
|
|
|
|
```sh
|
|
# Every ban.
|
|
curl -H "Authorization: Bearer $TOKEN" https://app.example/_smallwebwaf/bans
|
|
|
|
# Ban 203.0.113.0/24 for seven days.
|
|
curl -H "Authorization: Bearer $TOKEN" \
|
|
--json '{"netblock": "203.0.113.0/24", "duration": "7d", "reason": "probes for logins"}' \
|
|
https://app.example/_smallwebwaf/bans
|
|
|
|
# Lift the bans on 203.0.113.9.
|
|
curl -H "Authorization: Bearer $TOKEN" -X DELETE \
|
|
https://app.example/_smallwebwaf/bans/203.0.113.9
|
|
|
|
# What smallwebwaf knows of 203.0.113.9.
|
|
curl -H "Authorization: Bearer $TOKEN" \
|
|
https://app.example/_smallwebwaf/clients/203.0.113.9
|
|
```
