sneak 8e8bfe6718 Core Rule Set: Drupal's ordinary requests pass by default (closes #236)
check / check (push) Failing after 4m21s
Adds drupal.conf, the ninth change: on Drupal's paths, the fields that
carry a search, a name, a file name or an address skip the rules that
refused ordinary requests there. The recorded requests from Drupal 11.4
pass at the defaults and while bodies are read; SQL injection, path
traversal and script injection stay refused on those fields.

clawbot 719691d1e8 Name log fields, metrics and the Core Rule Set package for what they are (closes #192)
check / check (push) Failing after 3m22s
The first half of the naming audit: names now say what they are. `internal/waf` is `internal/coreruleset`. Log fields, the action `blocked_by_core_rule_set`, the metric and the alert event say Core Rule Set. Timings end `_ms`. Percentages say of what, as `rate_limit_percent` and `bytes_limit_percent`. Setting names follow in #234.

Judgement call: `blocked_by_core_rule_set`, not the audit's `core_rule_set_blocked`, to match `blocked_by_block_rule`.
Trips a reader: an existing state file holding `waf_blocked` or the anomaly scope `watch` stops the start and must be removed. `SWW_ALERT_EVENTS` listing `waf_block` must list `core_rule_set_match`.

clawbot aede434f6a Name request log actions so they say what they mean (closes #229)
check / check (push) Successful in 6m30s
The request log's `action` values now say what they mean, as sneak named them: `request_header_too_large`, `client_is_rate_limited`, `blocked_by_block_rule` and `client_denied`, with no aliases. `banned` splits into `temporarily_banned` and `permanently_banned`, by whether the ban runs out. When a permanent ban also covers a client, that ban is the one reported.

Trips a reader: a request over a rate limit stays `client_is_rate_limited` even when the ban it makes is permanent.
Disclosure: the offence key `rule_blocked` is renamed in `clients.json` too, so an existing file holding it stops the start and must be removed. Its `version` stays 1.

clawbot 6850cb0e9f Add asn= and prefix= tags from a routewatch instance (closes #204)
check / check (push) Successful in 5m0s
With `SWW_ROUTEWATCH_URL` set, a new heuristic, `routewatch_tags`, adds `asn=<number>` and `prefix=<netblock>` to a request from what a routewatch instance answers about the client. New package `internal/routewatch` asks in the background, never on a request's path, and keeps answers 1 hour in memory. The request log gains `routewatch_tags_missing`, saying why a request has none. `prefix=` works in `SWW_TAG_DENY` and `SWW_TAG_LIMIT_PERCENT`.

Trips a reader: a client's first request has no routewatch tags, so `prefix=` refuses from its next request after the answer comes.
Judgement call: with `SWW_LOOKUP_SOURCE=off` and `SWW_ROUTEWATCH_URL` set, an `asn=` tag no longer stops the start.

clawbot d7c62f2854 Say which bytes the byte limits count, and what passing one does (closes #203)
check / check (push) Failing after 3m48s
sneak asked for every document to be audited for sentences that do not say what they mean. The byte limits now say which bytes count (response bodies, request bodies or both, as `SWW_BYTES_COUNT` says, WebSocket traffic included) and what passing one does. Other unclear or false sentences in `README.md`, `SPEC.md`, `EVALUATION.md` and `docs/` are rewritten.

Documents only. `REPO_POLICIES.md` is shared policy text and stayed out.

clawbot c66277b111 Request tags, with refusing and limits per tag (closes #175)
check / check (push) Failing after 5m8s
Each request gets tags, logged as `tags`: `asn=`, `country=`, one per `SWW_TAG_LISTS` list holding the client, `crowdsec`, `dnsbl=<zone>`, `abuseipdb` and `exploitsignature`. `SWW_TAG_DENY` refuses by tag and `SWW_TAG_LIMIT_PERCENT` lowers limits by tag. They replace `SWW_ASN_LIMIT_PERCENT`, `SWW_COUNTRY_LIMIT_PERCENT` and `SWW_DENIED_COUNTRIES`, with no aliases. A tag in those settings that nothing configured can give stops the start.

Judgement call: `SWW_ASN_LIMIT_PERCENT_URL` stays, its entries counting like `asn=` tags.
Judgement call: `SWW_TAG_LIMIT_PERCENT` also lowers byte limits, as the settings it replaces did.
Trips a reader: `sww_country_list_refusals_total` now counts only `SWW_EXCLUSIVELY_ALLOWED_COUNTRIES` refusals.

sneak f6435b1a73 Add make publish: build the image on the Docker host and push it to the registry
check / check (push) Successful in 3m23s
`script/publish` runs `script/docker` against the Docker host and pushes the image to the registry under four tags: the UTC date, the short commit hash, the branch name and `latest`. It refuses a working tree with uncommitted changes, since the hash tag names a commit.

Also carries sneak's `golines -m 77` line wrapping in three files, with no code change.

Unverified: a real build on the Docker host and a real push from this commit.
Deviation: sneak's FIXME comments are out, because the linter refuses them; they are #227, #228 and #229.

clawbot 2349b2a081 discriminator: each decision heuristic is its own module (closes #195)
check / check (push) Failing after 1m53s
Each discriminator check is now a type in its own file behind one small interface, listed in `heuristics.go`. Adding a heuristic is one file and one line. Behaviour does not change.

Refusal and ban log lines gain `heuristic` and `heuristic_figures`. A ban after the answer, by `refusal_limit` or `byte_limits`, logs `after_answer_heuristic` and its figures, so one line can name both.

Deviation: four lists, not the planned three, so `refusal_limit` still bans at the decision.
Rule suppressed: `//nolint:lll` on one struct tag.

check / check (push) Successful in 5m24s
xz-utils, which nix-bin depends on, links its man pages with update-alternatives when it installs, and the image's dpkg config drops man pages, so each link printed a warning. A config file re-includes only the man1 pages for this install; the same step deletes them, their dangling links in /etc/alternatives and the config file. No man page or package is added or removed.

clawbot a41d61e9ad Install the image's Ubuntu packages from the normal mirrors (closes #190)
check / check (push) Successful in 3m14s
The image's `ca-certificates`, `nix-bin` and `runit` now come from Ubuntu's archive instead of a dated snapshot, whose service had failed image builds. apt fetches them over plain HTTP and checks each against the archive's signed package lists, so no CA certificates are borrowed from the Go image. The README, `SPEC.md` and `docs/image.md` say so; the amd64-only limit, which came from the removed hash check, is gone.

Rule cut against: `REPO_POLICIES.md` pins every external reference by hash; sneak's ruling at sneak/prompts#72 (comment) allows Ubuntu's own package index.

New defaults, as sneak approved: 120 requests a minute, 1,500 an hour and 6,000 a day; bytes off a minute, 50G an hour and 100G a day. The README, `SPEC.md`, `docs/settings.md` and `docs/gitea.md` give the new figures and reasoning, and point Actions runners and shared addresses at `SWWAF_RATE_LIMIT_EXEMPT_NETS`. The README examples now hold against the new defaults.

An Actions runner that is not exempted makes more requests an hour than the new limit and will be banned.

The package passes nothing on since the one-process mode went: it answers rproxy's questions, takes its reports and answers servewaf's own endpoints.

check / check (push) Successful in 3m50s
A compose setup that runs gitea 1.27.3 behind traefik, rproxy and servewaf on one shared network with IPv4 and IPv6, and `script/gitea-setup` (`make gitea-setup`), which brings it up and checks that a page load, a push and a clone pass through rproxy and are checked by servewaf. Containers on the shared network skip servewaf's checks; the gateways do not. gitea gets a secret key made per install and has sign-up off. `docs/gitea.md` explains each setting.

Judgement call: the Core Rule Set runs in `detect` mode here until #198 lands.

clawbot 344ce13c96 rproxy and servewaf replace the one-process smallwebwaf (closes #172, closes #165)
check / check (push) Failing after 14m44s
`smallwebwaf` with no command now prints the commands and exits with status 2.
The image runs rproxy, or servewaf with SMALLWEBWAF_COMMAND=servewaf. The
passing-on code, its settings and its log fields and metric go. internal/proxy
keeps the checks, answers, reports and own endpoints; its tests run through the
real rproxy. The documents describe the pair.

Judgement call: clients.json keeps token_refused, since state files refuse unknown fields.
Deviation: script/gitea-requests sets SWWAF_LOG_REQUEST_HEADERS, to label requests.
Partially verified: make example-app and make gitea-requests never built the image, as Ubuntu's snapshot service answered 5xx.

clawbot 17c5dd2438 rproxy, the proxy in front of each app, asks servewaf and fails open (closes #171)
check / check (push) Successful in 7m25s
`smallwebwaf rproxy` reads the first 64 KiB of each body, asks servewaf over
HTTP/1.1, and passes what servewaf allows to the app within its limits. Any
other answer goes to the visitor as servewaf gave it. SWRP_DEFAULT_DISPOSITION
decides only when servewaf cannot be connected to, does not answer at all, or
does not answer within SWRP_TIMEOUT_MS. A method SPEC.md does not list gets 405.

Duplication: internal/rproxy copies passing-on code from internal/proxy until
#172 removes the originals.
Rule suppressed: gosec G704 and G705; gosec at
internal/smallwebwaf/rproxy_test.go:431; tagliatelle at

check / check (push) Successful in 8m31s
A question waits on GeoJS at most 800ms, the new default of
SWWAF_LOOKUP_TIMEOUT. In enforce mode it does not wait at all when it is
over the header limits, on a fetched blocklist with deny, on the CrowdSec
decision list, or over a whole rate limit. Not waiting never lowers a
client's limit. Just before the Core Rule Set, servewaf refuses more than
50 cookies or 100 header fields with 431.

Shared default changed: SWWAF_LOOKUP_TIMEOUT also applies to smallwebwaf
with no command.
Judgement call: SWWAF_REPUTATION_TIMEOUT stays 2s, since no request waits
on the DNS blocklists or AbuseIPDB.

clawbot 2eeea136e8 servewaf answers rproxy's question about each request and takes its report (closes #170)
check / check (push) Failing after 14m16s
`smallwebwaf servewaf` runs today's checks on the visitor's request each
question carries, answers rproxy, and passes nothing to an app. rproxy reports
every request servewaf answered. A report counts an allowed request's bytes and
writes servewaf's second log line. The table holds a copy of what a report
needs, never the request, so a report cannot reach a request being handled.

Judgement call: a question's body is read before any check; over 64 KiB gets 400.
Judgement call: a report's bytes and durations have ceilings, so they cannot overflow.
Judgement call: a `close` disposition for SWWAF_BAN_RESPONSE=close.

clawbot 718a2c94b2 Default request limits per minute, hour and day, sized for API use (closes #176)
check / check (push) Failing after 17m45s
The default request limits now suit programmatic use of an API, such
as an automation fleet on another host, and still catch abusive bots:

- per minute: 500, room for a fleet's busiest minute and a few first
  visits with an empty cache, and passed within seconds by a client
  firing as fast as it can;
- per hour: 20000, passed by a client that keeps up 6 a second;
- per day: 300000, passed by a scraper that keeps up 4 a second.

The byte limits and ban lengths are unchanged. SPEC.md, README.md and
docs/settings.md give the reasons; docs/gitea.md redoes the Actions
runner sums.

Judgement call: the docs/alerts.md ban example shows the minute limit.

clawbot fdabf4974b Health check test uses addresses nothing can connect to (closes #158)
check / check (push) Canceled after 0s
TestHealthCheck closed the app's server, and later smallwebwaf, and
expected connections to the freed ports to fail. Another test could take
such a port in between, so the connection succeeded and the test failed.

The failing app check now uses the multicast address 224.0.0.1, to which
TCP cannot connect. The failing smallwebwaf check uses port 0, on which
nothing listens. Neither result depends on other processes. The test now
stops smallwebwaf after its last check, so that it exits before the
test's temporary directories are removed. The code under test is
unchanged.

clawbot a9dc59546b New defaults for the request and byte limits (closes #161)

The request limits and the hour and day byte limits now sit about twice
above what 40 people busy with heavy web apps make together on one
address:

- requests: 6000 a minute, 100,000 an hour, 1,000,000 a day;
- bytes: 20 GiB an hour, 200 GiB a day.

The largest response drops from 5 GiB to 1 GiB. The minute byte limit
of 4 GiB is sized to hold two of the largest responses with their
requests. SPEC.md gives the new reasoning; README.md and the reference
documents give the new figures.

An admin whose own address is banned lifts that ban by editing `bans.json` (see No check runs on these requests. A missing or wrong token is answered `401`. An
[`bans.md`](bans.md)). endpoint whose token is unset answers `404`, as does any other path.
`sww rproxy` answers only the health check of these, at its own address. It asks
`discriminator` about any other request under `/_sww/`. One that passes the
checks is answered `404`, so that the app never sees that prefix (see "`rproxy`"
in [`SPEC.md`](../SPEC.md)).

With `SWW_ADMIN_TOKEN` set, the token in `$TOKEN`, and `discriminator` reached
as `discriminator:8080` on its network:

## Repeats and the hourly cap
A repeat is an alert for the same event on the same netblock, source, file or
thing counted, less than `SWWAF_ALERT_COOLDOWN` after the last. It is held back
and counted, and the next alert sent gives the count. Past
`SWWAF_ALERT_MAX_PER_HOUR` alerts in an hour, the rest are held back and counted
by event. Once the hour ends, one alert with the event `summary` gives those
counts. It also counts the repeats that a cooldown held back and that no later
alert reported.
## Sending
Each destination has a queue of at most 1000 alerts, sent one at a time, so a
slow destination holds up nothing. A `2xx` answer takes an alert. A `4xx` other
than `408` and `429` refuses it, and it is dropped. Anything else is a failure:
the alert is sent again a second later, and twice as long after each further
failure, up to a minute. `alerts.json` keeps the queues and cooldowns across a
restart (see [`state-files.md`](state-files.md)).

# Bans
How bans are made, what they cover and how long they last is under "Bans" in
[`SPEC.md`](../SPEC.md); the settings are under "How long bans last and what
they cover" in [`settings.md`](settings.md). This file says what a ban's notes
hold, and how to make, keep or lift a ban.
## The notes
Each ban carries notes for deciding whether to lift it, drawn from what
`smallwebwaf` already knows. Nothing is looked up to fill them:
- the AS number, AS name and country, added when the lookup answers (empty when
lookups are off);
- what was broken: the rule id and target that matched, or the trap path, or the
limit, its window and the count reached;
- the client's percentage of the limit, with the setting that gave it;
- the reputation sources the client is on;
- the request that caused the ban: time, method, host, path with its query
string, status and user agent, each text cut to 256 bytes;
- the netblock's requests since it was first seen, and how many this ban has
refused so far, kept up to date while the ban lasts;
- how many earlier bans the netblock had, by cause.
## Managing bans by editing `bans.json`
`bans.json` in the state directory holds every ban, indented to be read. A
permanent ban's `expires` is `null`. `smallwebwaf` watches the file and takes in
an edit as soon as it is saved (see [`state-files.md`](state-files.md)).
To ban a netblock, add an entry with its `netblock`, `start` and `expires`.
`expires` is `null` for a ban that never ends. `reason`, `notes` and `cause` may
be left out; the cause is then `admin`:
```json
{
"version": 1,
"bans": [
{
"netblock": "203.0.113.0/24",
"start": "2026-10-06T12:00:00Z",
"expires": null,
"reason": "probes for logins"
}
]
}
```
To keep a ban `smallwebwaf` made, so that it is never dropped, set its `cause`
to `admin`. To lift a ban, add `"lifted"` with the time you lift it, such as
`"lifted": "2026-10-06T13:00:00Z"`. The ban then refuses nothing and does not
make the netblock's next ban longer. It is kept with its notes. To forget a ban,
delete its entry. A ban whose cause is `attack` becomes permanent at the first
request it refuses. One whose cause is `admin` or `crowdsec` does not.
An edit that cannot be read does not stop the running `smallwebwaf`. It keeps
what it holds. At the file's next write it renames your file to `bans.json.bad`,
writes the file again from memory, and logs and alerts the error. Mend the
`.bad` file and move it back.
## Managing bans through the admin endpoints
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" \

See [`admin-endpoints.md`](admin-endpoints.md) for what each answers. An admin
whose own address is banned lifts that ban by editing `bans.json`.

# The Core Rule Set
The OWASP Core Rule Set 4.25.0 runs on each request after the rule files, unless
`SWWAF_WAF_MODE` is `off`. It reads the method, the URL with its query, and the
headers. Once `SWWAF_WAF_BODY_LIMIT` is set, it also reads a body that is form
data, multipart, JSON or XML. No answer is inspected. The settings are under
"Attack detection" in [`settings.md`](settings.md). The same section of
[`SPEC.md`](../SPEC.md) says why bodies are not read by default, and gives the
six changes `smallwebwaf` makes to the Core Rule Set, with the reason for each.
Each rule that matches adds to the request's score. A score at or over
`SWWAF_WAF_ANOMALY_THRESHOLD` is a match. A match is refused with `403` while
`SWWAF_WAF_MODE` is `block`, and let through while it is `detect`. Either way
the log line gives the rule ids and the score, and a `waf_block` alert is sent.
A request with more than 1000 query parameters or body fields adds 5 to its
score, since Coraza reads only the first 1000. The Core Rule Set inspects only a
request that every earlier check let through. It skips a path under
`SWWAF_WAF_EXEMPT_PATHS` and a client in `SWWAF_ALLOW_NETS`. An engine error on
a request forwards the request, and is logged and counted.
Body inspection suits apps whose forms carry no code. In front of a code forge
it refuses issue and comment text, wiki pages and files saved in the web editor
that hold shell commands or code. The log line names the rule ids, which
`SWWAF_WAF_DISABLED_RULES` can switch off. A body the Core Rule Set cannot parse
adds 5 to the score. So does a multipart body cut by the limit in the middle of
a part's header. The client has until `SWWAF_CLIENT_REQUEST_TIMEOUT` runs out to
send the part that is read. Any other body, such as a git push, reaches the app
uninspected.
[`gitea.md`](gitea.md) records what the Core Rule Set still refuses in front of
gitea, with and without body inspection.

# smallwebwaf in front of gitea
These notes record what `smallwebwaf` does in front of gitea at the default
settings. They are observations, not requirements; the requirements are in
[`SPEC.md`](../SPEC.md). `script/gitea-requests` runs gitea behind the image and
sends through it a sample of gitea's ordinary use and the requests named below.
It reports each request the Core Rule Set refuses, so that these notes can be
checked again when gitea or the Core Rule Set changes version.
## What the defaults cover
- SSH access to gitea does not pass through `smallwebwaf` and is not protected
by it.
- A clone is a response. It fits the defaults of 30 minutes and 5 GiB for all
but the largest repositories and slowest links.
- A push is a request, and so is every other upload: a git push, an LFS object,
a container image layer, a package file or a release attachment. At the
defaults, an upload larger than 100 MiB or taking more than 60 seconds is cut
off. The client is answered `413` for a body that is too large, before
anything reaches gitea when the request announces its size. It is answered
`408` for a body it sends too slowly, or `504` if gitea is too slow to take
it. The upload fails, and no one is banned for it. A gitea that takes large
uploads needs `SWWAF_REQUEST_MAX_BYTES`, `SWWAF_CLIENT_REQUEST_TIMEOUT` and
`SWWAF_UPSTREAM_REQUEST_TIMEOUT` raised to fit. The Core Rule Set does not
read an upload's body, which streams through without being held in memory.
- Archive download and blame or history pages are what scrapers hammer. The
request limits do most of the work there.
- An Actions runner that reaches gitea through `smallwebwaf` sends requests all
day. One older than version 0.4 (April 2026) asks for work every 2 seconds,
43,200 requests a day, and reports a running job's log and state every second.
So it passes the day limit of 50,000 after about an hour and a quarter of
jobs. It is then banned, the job it is running fails, and each repeat within a
day makes the ban longer. Newer runners ask less often, but a busy one, or
several on one address, can still pass it. Put the runners' addresses in
`SWWAF_RATE_LIMIT_EXEMPT_NETS`. That takes them out of the request and byte
limits, while the error burst, attack detection and bans still apply.
## What the Core Rule Set lets through
At the defaults, the Core Rule Set lets gitea's ordinary use through, apart from
the refusals in the next section:
- browsing and views of files in a repository, with their history, blame and the
file tree;
- diffs, including their hidden lines and large files, and pull request review;
- git's clone, fetch and push over HTTP;
- signing in, including the return to the page a visitor came from, and sign-in
with Git Credential Manager, git-credential-oauth or tea;
- the API's calls for a file and its commits;
- pushing and pulling container images and packages;
- Actions runners, and artifacts uploaded with `actions/upload-artifact@v4`;
- posting issues, pull requests, comments, wiki pages and files saved in the web
editor, code included, since no body is read;
- the page gitea shows after a change, with its message naming what was done.
## What the Core Rule Set still refuses
Each refusal answers only that request, with `403`, and bans no one by itself.
It counts toward the error burst, which a person does not reach this way. The
request log names the rule in `waf_rule_ids`, which `SWWAF_WAF_DISABLED_RULES`
can switch off.
### A query string that reads as an attack
Most often this is a search. Every query parameter is checked against the Core
Rule Set's lists of system files and commands, except the ten named under
"Attack detection" in `SPEC.md`. A release attachment uploaded through the API
as `docker-compose.yml` is refused the same way. Examples:
- a name on those lists, such as `package.json`, `.gitignore` or
`docker-compose.yml`;
- text that starts with a command name, or whose first word has one right after
a `/`, such as `python3`, `ssh key` or `feat/docker-support`;
- a shell command with its options or a system path (`ls -la`, `sed -i`,
`/bin/sh`), or a command in backticks;
- script code (`fetch(`, `${VAR}`, `process.env`), HTML (`<img src=`) or an SQL
statement (`SELECT * FROM users WHERE`);
- a URL naming an IP address or `localhost`.
### A branch, tag or file name that starts with a command name
The Core Rule Set's list of commands (932260) holds names such as `docker-`,
`python3`, `ansible`, `base64` and `whoami`. A branch, tag or file name that
starts with one is refused. So is one that has such a name right after a `/`,
such as `feat/docker-support`, `fix/docker-build` or
`renovate/docker-build-push-action-6.x`. gitea's own pages send the name in a
query parameter that 930120, 932160 and 932260 still check:
- `refSubUrl`, the branch or tag of a directory listing. It is sent when the
listing asks for its entries' last commits in a second request, which it does
whenever gitea takes more than a second to work them out;
- `name`, when a branch is deleted or restored on the branches page;
- `tag`, when a release is started from a tag;
- `template`, the file of an issue template, when an issue is opened from it;
- `rule_name`, when a branch protection rule is opened for editing in the
repository's settings or has just been saved.
What a visitor sees, for a branch named `docker-build`:
- A directory listing that makes that second request leaves those last commits
out and shows an error.
- The branches page shows an error instead of deleting or restoring the branch.
- A release started from such a tag gets the `403` answer of `smallwebwaf` in
place of its form. So does an issue opened from such a template, and such a
rule opened for editing.
- Saving such a rule stores it. gitea then returns to the branch settings page,
which gets the `403` answer, so the save looks as if it failed.
### A file name in a query parameter that trips the code rules
The Core Rule Set's rules for Java, script, PowerShell and SQL find what they
look for in some file names. This holds in the parameters `smallwebwaf` leaves
out of 930120, 932160 and 932260 too (see the changes to the Core Rule Set under
"Attack detection" in `SPEC.md`). Examples:
- `runtime` in OpenJDK's `src/java.base/share/classes/java/lang/Runtime.java`
(944110);
- a Java class, as in `java.lang.String.md` (944130);
- `document.write.js` (941180);
- `process.env.d.ts` (934100);
- `__proto__` (934130);
- the PowerShell command `Install-Script`, as in `install-script.sh` (932120);
- a database's name, as in PostgreSQL's `information_schema.sql` (942140).
For such a file, these requests are refused:
- the API's list of its commits (`path`);
- the API's call for the contents of files that names it in its query (`body`);
- the commit graph of that file alone (`file`);
- the hidden lines of its diff (`path`), which stay hidden;
- the sign-in page gitea sends a visitor to on the way to a page of the file
that needs signing in, such as its edit page (`redirect_to`). The visitor can
still sign in by opening the sign-in page itself.
### A path
- A file name ending in `~`, or an `.xhtml` file whose path holds a space.
- A path that holds what the Core Rule Set takes for a Java class (944130), as
`java.lang.String.md` and
`META-INF/services/org.apache.commons.logging.LogFactory` do.
- A path that holds what it takes for Node.js code (934100), as
`process.env.d.ts` does.
- A path with a directory named `...` (930100, 930110), such as `.../notes.txt`.
For such a file, the page of the file, its raw file, its history, its blame and
its edit page are refused. The directory that holds it lists it, and a clone
carries it.
### A container image push that reuses a layer
A push can reuse a layer of an image docker has pushed to that gitea before.
docker then asks gitea to take the layer from that image, naming it in the query
parameter `from`, which 932260 checks. The request is refused when the image's
owner, or its name after the owner, starts with an entry on the list of
commands. Examples are `owner/python3-app`, `owner/docker-base`, and any image
of an owner named `ansible` or `docker-team`.
What happens next depends on docker's image store. A docker that keeps its
images in containerd's image store fails the push, and fails each new try the
same way. A new install of Docker Engine 29 does this. A docker that keeps them
in its own older image store uploads the layer instead. The push then succeeds
after one refusal for each layer it reuses, and each of those refusals counts
toward the error burst.
### Artifact uploads from `actions/upload-artifact@v3`
This action sends the header `Content-Range`, which the Core Rule Set refuses
(920450). The action sends two files at a time, does not retry a `403`, and
sends no further file once one is refused. So an upload is refused once or
twice, however many files it holds, and the step fails. One upload does not ban
the runner. More than 30 such refusals from its address within a minute, as when
many jobs upload at once, ban it through the error burst.
`actions/upload-artifact@v4` does not send the header.
## What body inspection refuses
With `SWWAF_WAF_BODY_LIMIT` set, the Core Rule Set reads request bodies too. In
front of gitea it then refuses these, until their rule ids, named in the request
log, are added to `SWWAF_WAF_DISABLED_RULES`:
- issue and comment text, wiki pages and files saved in the web editor that hold
shell commands or code (932125, 932235, 932250 and others);
- package descriptions that show code;
- PyPI uploads (922130);
- attachments named like `debug.log` or `config.yml` (932180).
## What `script/gitea-requests` sends
Of the requests above, the script sends:
- for each file named under "A file name in a query parameter that trips the
code rules", the API's list of its commits;
- for `Runtime.java` alone, the commit graph of that file, the hidden lines of
its diff, and the API's call for the contents of files that names it;
- the sign-in page gitea sends a visitor to on the way to the edit page of
`document.write.js`;
- the pages of `java.lang.String.md`,
`META-INF/services/org.apache.commons.logging.LogFactory`, `process.env.d.ts`
and `.../notes.txt`;
- one container image push that reuses a layer, which it does not try again.
It does not send the raw file, history, blame or edit page of those four files,
or the pages of the directories `META-INF/services` and `...`. It also sends a
short sample of gitea's ordinary use:
- signing in;
- pages of files and commits, and a diff;
- the API;
- a push, and clone and fetch over HTTP;
- two container image pushes.

# GeoJS and the lookup database
`smallwebwaf` looks up each client's AS number and country, through GeoJS by
default or in a database file on your own host. The settings are under "Looking
up the AS number and country" in [`settings.md`](settings.md); the reasons for
the defaults are under "Lookup of AS number and country" in
[`SPEC.md`](../SPEC.md).
## GeoJS
By default `smallwebwaf` asks GeoJS, a free web service that needs no account,
about every new visitor's address. It asks whether or not a setting uses the
answer, since the log line, the history, the ban notes and the metrics carry the
AS number and country. These addresses are never sent:
- one in `SWWAF_ALLOW_NETS` or `SWWAF_DENY_NETS`;
- one under a ban;
- a private, loopback or link-local address, which no source can place.
For an IPv6 visitor, GeoJS is asked about the first address of its group.
Addresses are asked about together, up to 200 in one request
(`https://get.geojs.io/v1/ip/geo.json?ip=a,b,c`), one request at a time. Each
answer's `country_code`, `asn` and `organization_name` are read. An answer
without a `country_code`, or with the `asn` `64512`, counts as unknown. Each
answer is kept for seven days, in memory and in `lookups.json`, separately from
the table of clients. Up to 100,000 answers are kept; past that, the answer used
longest ago goes first.
A request waits for its client's first answer only when a setting needs the
answer before the request goes on. It waits up to `SWWAF_LOOKUP_TIMEOUT`. The
settings that make it wait:
- a country list;
- `SWWAF_ADD_LOOKUP_HEADERS`;
- any setting under "Lower limits by AS number and country" in
[`settings.md`](settings.md).
Otherwise the request goes on at once, logged without the answer. The answer
reaches the client's history and ban notes when it comes. A client whose answer
has not come in time counts as from an unknown country until it comes, and its
later requests do not wait. While GeoJS fails, new visitors count as from an
unknown country, which `SWWAF_EXCLUSIVELY_ALLOWED_COUNTRIES` refuses. GeoJS is
then left alone for a second, and twice as long after each further failure, up
to five minutes, and one `source_failure` alert is sent per cooldown.
## The database file
To keep your visitors' addresses on your own host, set
`SWWAF_LOOKUP_SOURCE=off`, or set it to `file`. `file` looks every client up in
the free IPinfo Lite database (`ipinfo_lite.mmdb`) at `SWWAF_LOOKUP_DB_PATH`,
reading its `asn`, `as_name` and `country_code` fields. You download the
database with an IPinfo account and mount it into the container; `smallwebwaf`
never fetches it and holds no account or token for it. It answers at once, with
nothing sent off the host. A client whose address it does not hold counts as
from an unknown country.
`smallwebwaf` reads the whole file at start. It reads the file again once it has
gone 2 seconds without a change after you replace it. A replacement it cannot
read is logged and alerted, and the file read before stays in use. Mount the
directory that holds the file, not the file itself. Many editors and download
tools save a file by replacing it, and a container keeps seeing the old file
when only the file is mounted.
IPinfo updates the database daily, and releases it under the Creative Commons
Attribution-ShareAlike 4.0 licence. It asks for a link to IPinfo on the site
that uses it, such as "IP address data is powered by IPinfo".
## A client without a country
A client the lookup cannot place has an unknown country and AS number. That is
one of:
- a client on a private address;
- one GeoJS or the database does not know;
- one whose GeoJS answer has not come in time.
`SWWAF_EXCLUSIVELY_ALLOWED_COUNTRIES` refuses such a client, and the lower
limits give it `SWWAF_UNKNOWN_LIMIT_PERCENT`. Nothing else treats it
differently.

# Reputation sources
A reputation source judges a client by what others saw it do. None is on by
default. The settings are under "Reputation sources" in
[`settings.md`](settings.md); the reasons for the defaults are under
"Reputation" in [`SPEC.md`](../SPEC.md). The sources are checked in this order,
and a source the client is on refuses it, lowers its limits, or only notes it,
as `SWWAF_BLOCKLIST_ACTION` and `SWWAF_REPUTATION_ACTION` say.
## Blocklists
`SWWAF_BLOCKLIST_URLS` lists text files of addresses and netblocks, one to a
line, as the Spamhaus DROP list is written. Anything after a `;` or `#` is left
out. An IPv4-mapped address such as `::ffff:192.0.2.0/120` is read as the IPv4
netblock it stands for.
Each list is fetched again `SWWAF_BLOCKLIST_REFRESH` after its last try, one
list at a time. The file of `SWWAF_ASN_LIMIT_PERCENT_URL` is too.
`reputation.json` keeps when each was last tried, so a restart does not fetch a
list again before its time. A fetch fails when:
- the server answers other than `200`;
- the fetch does not finish within a minute;
- the list is longer than 16 MiB;
- a line is not an address or netblock, or, for the AS number file, not
`AS<number>:<percent>`.
The copy fetched before stays in use, comment lines included. The failure is
logged and raised as a `source_failure` alert. The log, the alerts, the ban
notes and the metrics name each list by its URL, so keep a secret out of it.
The Spamhaus DROP list is The Spamhaus Project's. Its terms, and what they mean
for `SWWAF_BLOCKLIST_REFRESH` and for several instances on one host, are under
"Reputation" in [`SPEC.md`](../SPEC.md). The copy in `reputation.json` keeps the
list's date and copyright lines.
## CrowdSec
While `SWWAF_CROWDSEC_LAPI_URL` is set to the local API of a CrowdSec engine you
run, `smallwebwaf` fetches its decision list every minute. It sends
`SWWAF_CROWDSEC_LAPI_KEY` in the `X-Api-Key` header. The list is kept as a
blocklist is kept. The decisions of the type `ban` on an address or a netblock
are used. Any other, such as a captcha or a country, is left out. A decision
lasts for the `duration` it had left when the engine answered.
A request is refused when a decision still in force names its client. The
client's netblock is banned until the decision ends, with the cause `crowdsec`.
Only a client that sends a request is banned, so a long list does not fill
`bans.json`. Such a ban is never made permanent, and does not lengthen the
netblock's next ban for a broken limit. If you lift a ban while the decision is
in force, the client's next request makes another. Delete the decision in
CrowdSec first, such as with `cscli decisions delete --ip 203.0.113.9`, and lift
the ban once the list has been fetched again. A fetch fails when:
- the engine answers other than `200`, a redirect included;
- the fetch does not finish within a minute;
- the answer is longer than 16 MiB;
- the answer is not a list of decisions.
## DNS blocklists
Each zone in `SWWAF_DNSBL_ZONES` is asked about a client's own address in the
background, the first time the client is seen. The request goes on at once, and
so does every request from the client until the zone has answered. The name
asked about is the one RFC 5782 gives: the numbers of an IPv4 address reversed,
or the 32 hex digits of an IPv6 address reversed. `192.0.2.99` is asked about as
`99.2.0.192.dnsbl.dronebl.org`. An answer in `127.0.0.0/8` lists the client, but
one in `127.255.255.0/24` is Spamhaus refusing the query. A name that does not
exist does not list the client. These are failures:
- an answer in `127.255.255.0/24`;
- an answer outside `127.0.0.0/8`;
- a resolver error;
- no answer within `SWWAF_REPUTATION_TIMEOUT`.
A failure is logged and alerted, and the zone is not asked again for a minute.
Each verdict is kept for `SWWAF_REPUTATION_CACHE_TTL`, in memory and in
`reputation.json`. Up to 100,000 verdicts are kept; past that, the one fetched
longest ago goes first. At most 1,000 queries are under way at once.
The key of a Spamhaus zone under `dq.spamhaus.net` is its first label.
`smallwebwaf` shows `********` in its place wherever it names the zone. Only
`reputation.json` keeps the zone with its key.
## AbuseIPDB
While `SWWAF_ABUSEIPDB_KEY` is set, `smallwebwaf` asks AbuseIPDB's check
endpoint for the abuse confidence score of a client, from 0 to 100. Only a
client that has committed an offence is checked. An offence is one of:
- a broken limit;
- a `ban` rule match or a trap path;
- a refusal by a `block` rule, the Core Rule Set or a token check.
The check runs in the background, at the client's first request after the
offence that no ban refuses, so no request waits. The score applies to the
client's later requests. For an IPv6 client, AbuseIPDB is asked about the
address of the request that set off the check, and the score is used for the
whole group. A score at or over `SWWAF_ABUSEIPDB_MIN_SCORE` is a hit, and
`SWWAF_REPUTATION_ACTION` says what is done. Each score is kept for
`SWWAF_REPUTATION_CACHE_TTL`, up to 100,000 scores.
At most `SWWAF_ABUSEIPDB_DAILY_BUDGET` checks are made in a day, counted in UTC
and kept in `reputation.json`. A restart does not make the budget whole again.
The check that spends the last of the budget is logged and alerted. No client is
checked until the day ends. A check fails when:
- AbuseIPDB answers other than `200`;
- the answer gives no score;
- no answer comes within `SWWAF_REPUTATION_TIMEOUT`.
A failure is logged and alerted, and no client is checked for a minute. The key
is sent in the `Key` header and nowhere else, and is never logged.

`sww discriminator` writes two lines for each question it answers, joined by
`request_id`. The field `discriminator_line` says which of the two a line is:
- `decision`: the line it writes once it has answered the question;
- `report`: the line it writes when `rproxy`'s report comes, with everything
known. The repetition is intended.
A request to its own endpoints writes one line, without `discriminator_line`. A
report writes no line but the `report` line of the request it names.
These questions write no line:
- a question refused with `400` (see "The question" under "`discriminator`" in
[`SPEC.md`](../SPEC.md));
- a question whose body stopped arriving, which gets no answer.

- `request_id`: a new random one of 26 letters and digits.
- `scheme`: `http`.

datagram. Over TCP and TLS each record follows its length in bytes and a space.
stdout is unchanged. The record carries:

the lines still waiting, and drops the rest. stdout has carried them. - `path` and `query`: as the visitor sent them.
- `status`: what the visitor got, `0` if nothing.
- `request_bytes`: the bytes of the visitor's body that `rproxy` read, with what
a WebSocket carried from the visitor.
- `response_bytes`: the bytes of the answer's body, with what a WebSocket
carried from the app.
- `duration_request_ms`: milliseconds from the request's headers being read
until the app had been sent the whole request, or the answer started if that
was sooner. It includes the wait for `discriminator`.
- `duration_response_ms`: milliseconds from then until the end of the answer.
- `disposition`: what was done with the request: `allow`, `deny` or `close`. It
is `discriminator`'s answer, or the value of `SWRP_DEFAULT_DISPOSITION`. It is
left out when:
- `discriminator` was not asked, as for the health check;
- the visitor went away while `discriminator` was being asked;
- `discriminator`'s answer had no valid `X-Sww-Disposition`;
- `rproxy` could not pass on `discriminator`'s answer, and answered `502`.
- `default_disposition`: `true` when `SWRP_DEFAULT_DISPOSITION` gave
`disposition`, and otherwise left out.

## Errors
These stop the start, with a message naming the file and line:

- a bad `header:` name, or a rule for `Host` or `Transfer-Encoding`;
- a regex that does not compile;
- an id used twice.
So does a `SWWAF_RULES_DIR` that does not exist. An empty directory is not an
error: the log says that no rules were loaded.
While it runs, `smallwebwaf` watches the directory. It reads the files again
once the directory has had no change for 2 seconds, so that a file still being
written is read whole. If the files then hold such an error, the rules stay as
they were. The log and a `file_error` alert name the file and line. Once the
file is fixed, it is read again.

## Mounting rule files Or mount it there. A `path` rule applies on every site behind that
`discriminator`.
A directory mounted over `/etc/smallwebwaf/rules.d` replaces the default file;
single files mounted into it add to it. Many editors save a file by replacing
it, and a container keeps seeing the old one when the file alone is mounted. So
rules to be edited while `smallwebwaf` runs belong in a mounted directory, with
a copy of the default file if the defaults are to stay. The lookup database is
mounted the same way, for the same reason. To run without rules, mount an empty
directory or set `SWWAF_RULES_ENABLED=false`.

log what `enforce` would have done. Observe mode still refuses a request over
a size or time limit, and one without the right token.
- `SWWAF_TRUSTED_PROXIES` (default `10.0.0.0/8,172.16.0.0/12,192.168.0.0/16`,
the private address ranges): the netblocks whose `X-Forwarded-For` is
believed, normally where traefik comes from. Set but empty, it trusts nothing:
every TCP peer is then the client.
- `SWWAF_IPV6_GROUP_PREFIX` (default `64`): the length of the netblock that is
one IPv6 client, from 32 to 128. After a change, each IPv6 client starts
afresh. Existing bans keep refusing their netblocks until they end.
- `SWWAF_MAX_TRACKED_CLIENTS` (default `20000`): the most clients kept in memory
and in `clients.json`, a whole number above zero. Past it, the least recently
seen client is dropped first.
## Time and size limits ## Tokens
Each request has limits on both sides: between the client and `smallwebwaf`, and - `SWW_ADMIN_TOKEN` (default unset): the token for the ban endpoints and
between `smallwebwaf` and the app. Bodies stream through in both directions, `/_sww/clients/<ip>`. At least 32 characters.
except the part the Core Rule Set reads while `SWWAF_WAF_BODY_LIMIT` is set. - `SWW_METRICS_TOKEN` (default unset): the token for `/_sww/metrics`. At least
32 characters.
- `SWWAF_CLIENT_REQUEST_TIMEOUT` (default `60s`): how long a client may take to ## State files
send its request line and headers, and then, from the end of the headers, its
body. A duration or `off`.
- `SWWAF_CLIENT_REQUEST_HEADER_MAX_BYTES` (default `32K`): the largest request
line and headers. A size over `4K`. It cannot be `off`: Go's HTTP server
always has such a limit.
- `SWWAF_CLIENT_IDLE_TIMEOUT` (default `120s`): how long a kept-open connection
may wait for its next request before it is closed. A duration or `off`. The
default is longer than the 90 seconds after which traefik closes an unused
connection, so traefik closes first.
- `SWWAF_CLIENT_RESPONSE_TIMEOUT` (default `30m`): how long the answer may take
to reach the client, from the end of the request to the last byte. A duration
or `off`.
- `SWWAF_UPSTREAM_REQUEST_TIMEOUT` (default `60s`): how long connecting to the
app and sending it the whole request may take. A duration or `off`.
- `SWWAF_UPSTREAM_RESPONSE_TIMEOUT` (default `30m`): how long the app may take
to send its whole answer. A duration or `off`.
- `SWWAF_REQUEST_MAX_BYTES` (default `100M`): the largest request body. A size
or `off`. A request that announces a larger body is refused before anything
reaches the app.
- `SWWAF_RESPONSE_MAX_BYTES` (default `5G`): the largest response body. A size
or `off`.
In front of a code forge, a clone is a response and a push is a request. At the - `SWW_STATE_DIR` (default `/var/lib/sww`): the directory of the state files, an
defaults, an upload over 100 MiB or slower than 60 seconds is cut off. A forge absolute path that exists and can be written.
that takes large uploads needs `SWWAF_REQUEST_MAX_BYTES`, - `SWW_STATE_WRITE_DELAY` (default `10s`): how long `bans.json` waits to be
`SWWAF_CLIENT_REQUEST_TIMEOUT` and `SWWAF_UPSTREAM_REQUEST_TIMEOUT` raised to written after a ban is made, lifted or made permanent. A duration.
fit. - `SWW_STATE_COUNTER_INTERVAL` (default `15m`): how often every state file is
written. A duration.
What the client gets when a limit is passed is under "Size and time limits" in
[`SPEC.md`](../SPEC.md).
## Netblock lists
- `SWWAF_ALLOW_NETS` (default empty): netblocks whose clients skip every check,
such as your monitoring or your own network. The size and time limits still
apply to them. They are not looked up. They still need a token for the admin
endpoints.
- `SWWAF_RATE_LIMIT_EXEMPT_NETS` (default empty): netblocks whose clients are
exempt from rate limiting and the byte limits, such as a machine that talks to
the app all day. Everything else still applies to them.
- `SWWAF_DENY_NETS` (default empty): netblocks whose clients are always refused.
A client in both lists is let through.
## Rate limiting and byte limits
- `SWWAF_RATE_LIMIT_PER_MINUTE` (default `1000`), `SWWAF_RATE_LIMIT_PER_HOUR`
(default `10000`) and `SWWAF_RATE_LIMIT_PER_DAY` (default `50000`): the most
requests a client may make in each window. A count or `off`. The defaults are
several times what one busy person produces. A browser loading a heavy page
makes a few hundred requests, and several people often share one address.
- `SWWAF_RATE_LIMIT_EXEMPT_PATHS` (default empty): path prefixes exempt from
rate limiting, such as `/assets/`. Their bytes are not counted either. The
path is matched exactly as sent, without the query, and is not
percent-decoded. `/assets/` matches `/assets/app.js`. It does not match
`/Assets/app.js`, `/%61ssets/app.js` or `/static/assets/app.js`. There are no
wildcards. A path holding `..`, a backslash or an encoded slash (`%2F`) is
never exempt, since the app may read it as a path outside the prefix.
- `SWWAF_BYTES_LIMIT_PER_MINUTE` (default `10G`), `SWWAF_BYTES_LIMIT_PER_HOUR`
(default `20G`) and `SWWAF_BYTES_LIMIT_PER_DAY` (default `50G`): the most
bytes a client may have counted in each window. A size or `off`. Bytes are
counted once the answer has ended, so a byte limit never cuts an answer short.
The client's next request is refused instead. Each default is above the
largest request and answer together, so at the defaults no single download
breaks a limit.
- `SWWAF_BYTES_COUNT` (default `both`): which body bytes the byte limits count:
`response`, `request` or `both`. For a WebSocket, what it carried each way
counts once it closes.
## Looking up the AS number and country
- `SWWAF_LOOKUP_SOURCE` (default `geojs`): `geojs`, `file` or `off`. `geojs`
asks the GeoJS web service, which is then told the address of every new
visitor. `file` looks clients up in the IPinfo Lite database file at
`SWWAF_LOOKUP_DB_PATH`, and sends nothing off the host. `off` looks up no
client. With `off`, a setting that needs lookups stops the start:
- a country list;
- `SWWAF_ADD_LOOKUP_HEADERS`;
- an entry in `SWWAF_ASN_LIMIT_PERCENT`, `SWWAF_COUNTRY_LIMIT_PERCENT`,
`SWWAF_ASN_BYTES_PERCENT` or `SWWAF_COUNTRY_BYTES_PERCENT`;
- `SWWAF_UNKNOWN_LIMIT_PERCENT` below 100;
- `SWWAF_ASN_LIMIT_PERCENT_URL`;
- an anomaly threshold per AS number.
- `SWWAF_LOOKUP_DB_PATH` (default empty): the IPinfo Lite database file, in its
`.mmdb` form, for `SWWAF_LOOKUP_SOURCE=file`. `file` without it stops the
start, and so does setting it with any other source. A file that is missing or
cannot be read stops the start too.
- `SWWAF_LOOKUP_TIMEOUT` (default `1s`): how long a request waits for its
client's first answer from GeoJS when a setting needs it, and how long a
request to GeoJS may take. A duration; it cannot be `off`.
- `SWWAF_ADD_LOOKUP_HEADERS` (default `false`): `true` passes the app the
client's AS number in `X-Client-ASN` and its country in `X-Client-Country`. A
header whose value is unknown is left out. Whatever this setting says, any
such header the client sent is removed.
See [`lookup.md`](lookup.md) for what each source sends where, and how long
answers are kept.
## Country lists
- `SWWAF_DENIED_COUNTRIES` (default empty): countries whose clients are refused,
such as `cn,ru,kp`.
- `SWWAF_EXCLUSIVELY_ALLOWED_COUNTRIES` (default empty): when set, the only
countries whose clients get through, such as `us,de`. A client whose country
cannot be found is refused too. Otherwise every new client would be let in
whenever GeoJS stops answering. A client on a private address has no country,
so it is refused unless it is in `SWWAF_ALLOW_NETS`.
A country on both lists stops the start. What a refused request gets, and why
the lists are empty by default, is under "Country lists" in
[`SPEC.md`](../SPEC.md).
## Lower limits by AS number and country
Clients of the AS numbers and countries listed here get a percentage of every
rate limit and byte limit. A lowered limit is rounded down. "Biased thresholds"
in [`SPEC.md`](../SPEC.md) says why the lists are empty by default and why no
budget is shared by a whole AS number or country.
- `SWWAF_ASN_LIMIT_PERCENT` (default empty): a list of AS numbers, each with `:`
and a percentage, such as `AS14061:50,AS16276:50,AS45102:25`. An AS number
listed twice is refused.
- `SWWAF_COUNTRY_LIMIT_PERCENT` (default empty): the same by country, such as
`cn:25,ru:50`.
- `SWWAF_ASN_BYTES_PERCENT` and `SWWAF_COUNTRY_BYTES_PERCENT` (default empty):
the same for the byte limits alone. For the AS numbers and countries they
list, they take the place of the two settings above.
- `SWWAF_UNKNOWN_LIMIT_PERCENT` (default `100`): the percentage of every limit
for a client without a country:
- one the lookup cannot place;
- one on a private address;
- one whose answer from GeoJS has not come in time.
- `SWWAF_ASN_LIMIT_PERCENT_URL` (default unset): the `http` or `https` URL of a
text file of such entries, one to a line, such as `AS14061:50`. One list can
then serve several instances. It is fetched and kept as a blocklist is. Where
it and `SWWAF_ASN_LIMIT_PERCENT` both give a percentage, the lower applies. A
URL that is also in `SWWAF_BLOCKLIST_URLS` stops the start.
A client to which several percentages apply gets the lowest. The log line of
each counted request, and the notes of each ban, say which setting lowered the
limit.
## Reputation sources
None is on by default. A reputation source judges a client by what others saw it
do. The defaults judge it by what it does to your service.
- `SWWAF_BLOCKLIST_URLS` (default empty): blocklists to fetch, such as
`https://www.spamhaus.org/drop/drop.txt`. Each is an `http` or `https` URL
without a user or a fragment. A URL listed twice is refused.
- `SWWAF_BLOCKLIST_REFRESH` (default `24h`): how long a list waits after its
last fetch, or failed try, before it is fetched again. A duration of `1h` or
more; it cannot be `off`. The Spamhaus lists may be fetched no more than once
an hour.
- `SWWAF_BLOCKLIST_ACTION` (default `deny`): what is done with a client on a
blocklist. `deny` refuses its requests. `limit:<percent>`, such as `limit:25`,
gives it that percentage of every limit. `log` only notes the list in the log
line and raises an alert.
- `SWWAF_DNSBL_ZONES` (default empty): the DNS blocklists to ask about each
client, such as `dnsbl.dronebl.org`. A DNS blocklist answers a DNS query for a
name made from an address, and so says whether the address is on it. A zone is
a DNS name of at most 189 characters. A Spamhaus zone carries its key, as in
`<key>.xbl.dq.spamhaus.net`, and is shown with the key masked. A zone listed
twice is refused, whatever its case or key. Do not name a zone meant for mail:
such a zone holds the residential addresses ordinary visitors come from.
- `SWWAF_DNSBL_RESOLVER` (default unset): the resolver to ask the zones through,
such as `192.0.2.53` or `[2001:db8::53]:5353`. An IP address with an optional
port, 53 when none is given. Unset, the host's resolver is used. Several zones
refuse queries that come through a public resolver.
- `SWWAF_ABUSEIPDB_KEY` (default unset): the key of your AbuseIPDB account.
While it is set, a client that has committed an offence is checked. A control
character in it is refused.
- `SWWAF_ABUSEIPDB_MIN_SCORE` (default `75`): the least abuse confidence score,
from 0 to 100, that is a hit.
- `SWWAF_ABUSEIPDB_DAILY_BUDGET` (default `900`): the most checks made in a day,
in UTC, a whole number above zero. AbuseIPDB's free accounts may make 1,000.
- `SWWAF_CROWDSEC_LAPI_URL` (default unset): the local API of a CrowdSec engine
you run, such as `http://172.17.0.1:8080`. An `http` or `https` URL without a
user or a fragment. Its decision list is at `v1/decisions` under that URL, and
is fetched every minute. Set without the key, it stops the start. So does a
decision list URL that is also in `SWWAF_BLOCKLIST_URLS`, or that is
`SWWAF_ASN_LIMIT_PERCENT_URL`.
- `SWWAF_CROWDSEC_LAPI_KEY` (default unset): the key the engine gave for
`smallwebwaf`, as `cscli bouncers add smallwebwaf` prints it. Set without the
URL, it stops the start.
- `SWWAF_REPUTATION_ACTION` (default `limit:25`): what is done with a client on
a DNS blocklist, or one whose AbuseIPDB score is a hit. `deny`,
`limit:<percent>` or `log`, as for `SWWAF_BLOCKLIST_ACTION`. Such a verdict is
less certain than the Spamhaus DROP list, so by default the client gets a
quarter of every limit.
- `SWWAF_REPUTATION_CACHE_TTL` (default `24h`): how long a zone's verdict or
AbuseIPDB's score is used. A duration; it cannot be `off`.
- `SWWAF_REPUTATION_TIMEOUT` (default `2s`): how long a query to a zone or a
check with AbuseIPDB may take. A duration; it cannot be `off`.
See [`reputation.md`](reputation.md) for how each source is asked and what it
does with the answer.
## Attack detection
- `SWWAF_RULES_DIR` (default `/etc/smallwebwaf/rules.d`): the directory of the
rule files (see [`rules.md`](rules.md)). A directory that cannot be read stops
the start. An empty one is no error.
- `SWWAF_RULES_ENABLED` (default `true`): `false` reads no rule file.
- `SWWAF_TRAP_PATHS` (default empty): paths the app never serves and only
scanners ask for, such as `/wp-login.php,/xmlrpc.php` in front of a code
forge. A request for one bans the client, as a `ban` rule does. Each starts
with `/` and holds no `?`. A trap path is matched whole, without the query,
against the path as sent and once percent-decoded. `/wp-login.php` matches
`/wp-login.php?x=1` and `/%77p-login.php`. It does not match `/wp-login.php/`
or `/blog/wp-login.php`.
- `SWWAF_WAF_MODE` (default `block`): what the Core Rule Set does with a request
it takes for an attack. `block` refuses it with `403`. `detect` lets it
through, logged and alerted. `off` inspects no request.
- `SWWAF_WAF_PARANOIA_LEVEL` (default `1`): the Core Rule Set's paranoia level,
from 1 to 4. Each level up runs more rules. Those find more attacks, and take
more ordinary requests for attacks.
- `SWWAF_WAF_ANOMALY_THRESHOLD` (default `5`): the score at which a request is a
match. Each rule that matches adds to the request's score, and a rule rated
critical adds 5. So by default one such rule is enough. A whole number above
zero, or `off`. With `off` no request is a match, and scores are still logged.
- `SWWAF_WAF_DISABLED_RULES` (default
`920340,920420,920440,920640,930130,930140`): the ids of Core Rule Set rules
to switch off. The log line names the rules a request matched, so a rule that
refuses your app's ordinary requests can be found there. "Attack detection" in
[`SPEC.md`](../SPEC.md) says what the six default ids refuse and why they are
off. A list you give replaces the default, so name these six ids in it to keep
them off. An id must be a whole number above zero. An id from 900000 to 900999
is refused: those are the rules that set the Core Rule Set up, and
`smallwebwaf`'s own.
- `SWWAF_WAF_EXEMPT_PATHS` (default empty): path prefixes the Core Rule Set does
not inspect, matched as `SWWAF_RATE_LIMIT_EXEMPT_PATHS` is.
- `SWWAF_WAF_BODY_LIMIT` (default `off`): `off` reads no request body. A size,
at most `1G`, switches body inspection on. The Core Rule Set then reads a form
data or multipart body up to that size, and the rest streams on to the app. It
reads a JSON or XML body no larger than that size, since those cannot be read
in part. Any other body, such as a git push, reaches the app uninspected. See
[`core-rule-set.md`](core-rule-set.md).
- `SWWAF_ERROR_BURST_THRESHOLD` (default `30`): the most refusals of one client
in a minute for a rule match, a trap path, a Core Rule Set match or a failed
token check. One more bans the client, as a broken rate limit does. A count or
`off`. The app's own `401` and `404` answers are not counted.
## How long bans last and what they cover
- `SWWAF_BAN_RESPONSE` (default `403`): how a refused client is answered: `403`,
`429`, or `close` to close the connection without an answer. A `block` rule
and the Core Rule Set always answer `403`.
- `SWWAF_LIMIT_BAN_DURATION` (default `1h`): the ban for a first broken rate
limit, byte limit or error burst. A duration; it cannot be `off`.
- `SWWAF_LIMIT_BAN_REPEAT_WINDOW` (default `24h`): a client that breaks a limit
again within this time after its ban ended is banned three times as long. A
duration; it cannot be `off`.
- `SWWAF_MAX_BAN_DURATION` (default `7d`): a ban for a broken limit that would
be longer is permanent instead. A duration; it cannot be `off`.
- `SWWAF_ATTACK_BAN_DURATION` (default `7d`): the ban for a first clear sign of
attack. A duration; it cannot be `off`.
- `SWWAF_MAX_BANS` (default `5000`): the most bans `smallwebwaf` made that are
kept, whether past, active or permanent. A whole number above zero. Bans whose
cause is `admin` are kept besides and never dropped (see
[`bans.md`](bans.md)).
- `SWWAF_BAN_SCOPE_V4_PREFIX` (default `32`): the length of the netblock around
an IPv4 client that a ban covers, from 0 to 32. `24` bans the surrounding /24.
An IPv6 ban covers the client's group.
## Where and how often the state files are written
- `SWWAF_STATE_DIR` (default `/var/lib/smallwebwaf`): the directory of the state
files, an absolute path. A directory that does not exist or cannot be written
stops the start.
- `SWWAF_STATE_WRITE_DELAY` (default `10s`): how long `bans.json` waits to be
written after a ban is made, lifted or made permanent. Every change in between
goes into the same write. A duration; it cannot be `off`.
- `SWWAF_STATE_COUNTER_INTERVAL` (default `15m`): how often every state file is
written. A duration; it cannot be `off`.
## Logging ## Logging
- `SWWAF_LOG_REQUEST_HEADERS` (default - `SWW_LOG_LEVEL` (default `info`): the least severe of `discriminator`'s own
messages that are written: `debug`, `info`, `warn` or `error`.
- `SWW_LOG_REQUEST_HEADERS` (default
`accept,accept-language,accept-encoding,content-type,origin,range`): the `accept,accept-language,accept-encoding,content-type,origin,range`): the
request headers to record in the log line, in either case. `Authorization`, request headers recorded in the log line, in either case. `Host` and
`Cookie` and `Set-Cookie` are never logged, even if listed. `Host` and `Transfer-Encoding` are refused; the host is the field `host`.
`Transfer-Encoding` are refused: Go's HTTP server takes them out of the - `SWW_LOG_REMOTE_URL` (default unset): a syslog server that also gets every
request. The host is the field `host`. line written to stdout: `syslog+udp://`, `syslog+tcp://` or `syslog+tls://`,
- `SWWAF_LOG_LEVEL` (default `info`): the least severe of `smallwebwaf`'s own each with a host and a port and nothing more.
messages that are written: `debug`, `info`, `warn` or `error`. No message is - `SWW_LOG_REMOTE_TLS_CA_FILE` (default unset): a file of PEM certificates that

the line of settings at start. A file that cannot be read, or holds no certificate, is refused.
- `SWWAF_LOG_REMOTE_URL` (default unset): a syslog server every line on stdout - `SWW_LOG_REMOTE_BUFFER` (default `10000`): the most lines held while they wait
is also sent to, such as `syslog+tls://logs.example:6514`. The forms are to be sent, a whole number above zero.
`syslog+udp://`, `syslog+tcp://` and `syslog+tls://`, each with a host and a - `SWW_LOG_REMOTE_FACILITY` (default `local0`): the syslog facility: `kern`,
port and nothing more.
- `SWWAF_LOG_REMOTE_TLS_CA_FILE` (default unset): a file of PEM certificates
that a `syslog+tls` server's certificate must chain to, instead of the host's
own. A file that cannot be read, or holds no certificate, stops the start.
- `SWWAF_LOG_REMOTE_BUFFER` (default `10000`): the most lines held while they
wait to be sent, a whole number above zero.
- `SWWAF_LOG_REMOTE_FACILITY` (default `local0`): the syslog facility: `kern`,
`user`, `mail`, `daemon`, `auth`, `syslog`, `lpr`, `news`, `uucp`, `cron`, `user`, `mail`, `daemon`, `auth`, `syslog`, `lpr`, `news`, `uucp`, `cron`,
`authpriv`, `ftp`, or `local0` to `local7`. `authpriv`, `ftp`, or `local0` to `local7`.
- `SWWAF_LOG_REMOTE_APP_NAME` (default: `SWWAF_INSTANCE_NAME`): the app name in - `SWW_LOG_REMOTE_APP_NAME` (default: `SWW_INSTANCE_NAME`): the app name in each
each syslog record, 1 to 48 printable ASCII characters without a space. syslog record, 1 to 48 printable ASCII characters without a space.
## Tokens and metrics ## Metrics
- `SWWAF_ADMIN_TOKEN` (default unset): the token for the ban endpoints and - `SWW_METRICS_TOP_N` (default `50`): how many AS numbers and how many countries
`/_smallwebwaf/clients/<ip>`. A long random value of at least 32 characters. get series of their own. A whole number above zero.
Unset, those endpoints are off. Give it as a file to keep it from the app (see
"Settings given as files" below).
- `SWWAF_METRICS_TOKEN` (default unset): the token a scraper sends for
`/_smallwebwaf/metrics`, at least 32 characters. Unset, the metrics are off.
It is separate from the admin token, so a scraper cannot manage bans.
- `SWWAF_METRICS_TOP_N` (default `50`): how many AS numbers and how many
countries get series of their own in the metrics. The rest count as `other`. A
whole number above zero.
## Alert destinations ## Static lists
- `SWWAF_ALERT_WEBHOOK_URL` (default unset): the webhook that receives each - `SWW_ALLOW_NETS` (default empty): netblocks you trust, such as your monitoring
alert as a JSON object. An `http` or `https` URL without a user or a fragment. (see step 4 in [`SPEC.md`](../SPEC.md)).
The settings logged at start show its path and query as `********`, since many - `SWW_RATE_LIMIT_EXEMPT_NETS` (default empty): netblocks whose clients are
webhooks carry their secret there. exempt from rate limiting and the byte limits.
- `SWWAF_ALERT_WEBHOOK_HEADERS` (default empty): headers sent with each post, - `SWW_DENY_NETS` (default empty): netblocks whose clients are refused (see step
such as `Authorization:Bearer 0123456789abcdef`. A list of name, `:` and 4 in [`SPEC.md`](../SPEC.md)).
value. A value cannot hold a comma.
- `SWWAF_ALERT_SLACK_WEBHOOK_URL` (default unset): the Slack incoming webhook
that receives each alert as a message. It is checked and masked as the webhook
URL is.
- `SWWAF_ALERT_NTFY_URL` (default unset): the ntfy topic that receives each
alert, as the topic's full URL, such as `https://ntfy.sh/my-alerts`. It is
checked and masked as the webhook URL is.
- `SWWAF_ALERT_NTFY_TOKEN` (default unset): an ntfy access token, sent as
`Authorization: Bearer <token>`. A control character in it is refused.
- `SWWAF_ALERT_EVENTS` (default
`ban,permanent_ban,waf_block,anomaly,reputation_hit,source_failure,file_error`):
the events alerts are sent for. Any other name is refused.
- `SWWAF_ALERT_COOLDOWN` (default `15m`): how long a repeat of an alert is held
back. A duration or `off`.
- `SWWAF_ALERT_MAX_PER_HOUR` (default `60`): the most alerts sent in an hour.
The rest are rolled into one summary. A whole number above zero, or `off`.
See [`alerts.md`](alerts.md) for the events and what each destination gets. ## Request rate limits, per client
The request past one of these limits is refused, and the client is banned.
- `SWW_RATE_LIMIT_PER_MINUTE` (default `120`, 2 a second): the most requests a
client may make in a minute. A count or `off`. The default leaves room for a
person opening two pages at once with an empty cache, up to 60 files each.
- `SWW_RATE_LIMIT_PER_HOUR` (default `1500`): the most requests a client may
make in an hour. A count or `off`. It is the main limit against scrapers. A
person reading a site for an hour, a page every 20 seconds, makes about 900. A
scraper making one request every 2 seconds makes 1,800 an hour, more than the
limit.
- `SWW_RATE_LIMIT_PER_DAY` (default `6000`): the most requests a client may make
in a day. A count or `off`. The default is four hours at the hour limit. A
scraper making one request every 10 seconds makes 8,640 a day, more than the
limit.
- A CI runner asks its code forge for work all day and can pass the limits. Put
the runners' addresses in `SWW_RATE_LIMIT_EXEMPT_NETS`. Do the same for a
network where many people share one address, such as an office.
- Counting cannot catch a client that stays under all three limits (see "Request
rate limits, per client" in [`SPEC.md`](../SPEC.md)).
- `SWW_RATE_LIMIT_EXEMPT_PATHS` (default empty): path prefixes exempt from rate
limiting and the byte limits, such as `/assets/`.
## Byte limits, per client
These count body bytes, never headers. What the visitor sent over a WebSocket
counts as request bytes, and what the app sent as response bytes. The bytes
counted for a request and its response are added to the client's total once the
response has ended. The request that takes a client's total past a limit is not
cut off; the client is banned.
- `SWW_BYTES_LIMIT_PER_MINUTE` (default `off`), `SWW_BYTES_LIMIT_PER_HOUR`
(default `50G`) and `SWW_BYTES_LIMIT_PER_DAY` (default `100G`): the most bytes
counted for a client in each window, a size or `off`. `SWW_BYTES_COUNT` says
which bytes count: response bodies, request bodies or both. The request that
passes the limit is not cut off, and the client is banned when its response
ends.
- `SWW_BYTES_COUNT` (default `both`): what the byte limits and the byte anomaly
thresholds count: `response`, the app's response bodies; `request`, the
visitors' request bodies; or `both`. What the visitor sent over a WebSocket
counts as request bytes, and what the app sent as response bytes.
## Lookup of AS number and country
- `SWW_LOOKUP_SOURCE` (default `geojs`): `geojs`, `file` or `off`. `off` stops
the start while a setting that needs a lookup is set:
- `SWW_EXCLUSIVELY_ALLOWED_COUNTRIES`;
- `SWW_ADD_LOOKUP_HEADERS`;
- `SWW_TAG_DENY` or `SWW_TAG_LIMIT_PERCENT` naming a `country=` tag, or an
`asn=` tag while `SWW_ROUTEWATCH_URL` is unset;
- the two byte percentage lists and `SWW_ASN_LIMIT_PERCENT_URL`;
- `SWW_UNKNOWN_LIMIT_PERCENT` below `100`;
- an anomaly threshold per AS number.
- `SWW_LOOKUP_DB_PATH` (default empty): the IPinfo Lite database file, in its
`.mmdb` form, for `SWW_LOOKUP_SOURCE=file`.
- `SWW_LOOKUP_TIMEOUT` (default `800ms`): how long a request waits for its
client's first answer from GeoJS, and how long a request to GeoJS may take. A
duration; never `off`.
- `SWW_ADD_LOOKUP_HEADERS` (default `false`): `true` has `rproxy` pass the app
the client's AS number in `X-Client-ASN` and its country in
`X-Client-Country`.
## Country list
- `SWW_EXCLUSIVELY_ALLOWED_COUNTRIES` (default empty): when set, the only
countries whose clients get through, such as `us,de`. A country whose
`country=` tag is in `SWW_TAG_DENY` stops the start.
## Request tags
Every request gets tags from what `discriminator` knows of its client. See
"Request tags" in [`SPEC.md`](../SPEC.md).
- `SWW_TAG_LISTS` (default empty): address lists that each add a tag, as
`name=URL` pairs, such as `torexit=https://example.com/tor.txt`. A name is the
tag, and may hold `=`, such as `vpn=mullvad`. Each list is an `http` or
`https` URL fetched like a blocklist. A name or URL listed twice is refused.
So is a URL that is also in `SWW_BLOCKLIST_URLS`, `SWW_ASN_LIMIT_PERCENT_URL`,
or the CrowdSec decision list.
- `SWW_TAG_DENY` (default empty): tags whose requests are refused, such as
`torexit,country=CN`. A tag listed twice, an `asn=` tag without a number, or a
`country=` tag without a country, is refused.
- `SWW_TAG_LIMIT_PERCENT` (default empty): tags that lower a client's limits, as
tag and percentage pairs, such as `vpn:50,asn=14061:25`. A percentage is from
`1` to `99`, of every rate limit and byte limit. The lowest percentage among a
client's tags applies. A tag listed twice is refused. So is
`exploitsignature`: a request gets that tag after the rate limits have counted
it.
- `SWW_ROUTEWATCH_URL` (default unset): the `http` or `https` URL of a
routewatch instance. [routewatch](https://git.eeqj.de/sneak/routewatch) is a
service that gives an address's announced netblock and origin AS.
`discriminator` asks it about each client, in the background, and adds the
tags `asn=<number>` and `prefix=<netblock>` from its answer. While it is
unset, nothing asks routewatch and no request gets a `prefix=` tag.
`SWW_TAG_DENY` and `SWW_TAG_LIMIT_PERCENT` accept tags in either case. A tag
that no request can get stops the start. A request can get only these:
- a name in `SWW_TAG_LISTS`;
- an `asn=` or `country=` tag;
- a `prefix=` tag with a netblock, while `SWW_ROUTEWATCH_URL` is set. It matches
only that exact announced netblock, such as `prefix=192.0.2.0/24`;
- a `dnsbl=` tag of a zone in `SWW_DNSBL_ZONES`, in lower case, with a key
masked as the `reputation` field shows it;
- `abuseipdb`, while `SWW_ABUSEIPDB_KEY` is set;
- `exploitsignature`, in `SWW_TAG_DENY` only, while `SWW_RULES_ENABLED` is
`true`, or while neither `SWW_WAF_MODE` nor `SWW_WAF_ANOMALY_THRESHOLD` is
`off`.
`crowdsec` stops the start in both settings, because a CrowdSec decision refuses
the request first.
## Biased thresholds
- `SWW_ASN_BYTES_PERCENT` and `SWW_COUNTRY_BYTES_PERCENT` (default empty): a
percentage of the byte limits alone, for the AS numbers or countries listed,
such as `AS14061:50` or `cn:25`. It takes the place of the percentage
`SWW_TAG_LIMIT_PERCENT` gives their `asn=` or `country=` tag. An AS number or
country listed twice is refused.
- `SWW_UNKNOWN_LIMIT_PERCENT` (default `100`): the percentage for a client the
lookup cannot place.
- `SWW_ASN_LIMIT_PERCENT_URL` (default unset): the `http` or `https` URL of a
text file with one AS number and percentage on each line, such as
`AS64496:50`. Each entry counts like an `asn=` tag in `SWW_TAG_LIMIT_PERCENT`.
A URL that is also in `SWW_BLOCKLIST_URLS` is refused.
## Attack detection
- `SWW_RULES_DIR` (default `/etc/sww/rules.d`): the directory of the rule files.
- `SWW_RULES_ENABLED` (default `true`): `false` reads no rule file.
- `SWW_TRAP_PATHS` (default empty): paths only scanners ask for, such as
`/wp-login.php,/xmlrpc.php`. Each starts with `/` and holds no `?`.
- `SWW_WAF_MODE` (default `block`): `off`, `detect` or `block`.
- `SWW_WAF_PARANOIA_LEVEL` (default `1`): the Core Rule Set's paranoia level,
from 1 to 4.
- `SWW_WAF_ANOMALY_THRESHOLD` (default `5`): the score at which a request is a
match. A whole number above zero, or `off`.
- `SWW_WAF_DISABLED_RULES` (default
`920340,920420,920440,920640,930130,930140`): the ids of Core Rule Set rules
to switch off. Each a whole number above zero. An id from 900000 to 900999 is
refused: those are the rules that set the Core Rule Set up, and
`smallwebwaf`'s own.
- `SWW_WAF_EXEMPT_PATHS` (default empty): path prefixes the Core Rule Set does
not inspect.
- `SWW_WAF_BODY_LIMIT` (default `off`): `off`, or how much of a request body the
Core Rule Set reads, a size of at most `64K`. A question carries no more of a
body than 64 KiB, and the Core Rule Set reads at most 64 KiB less one byte of
it, whatever the value (see "The answer" in [`SPEC.md`](../SPEC.md)).
- `SWW_CORE_RULE_SET_EXCLUSIONS_FILE` (default unset): a file of Core Rule Set
exclusions, written as Coraza directives. It is loaded before the Core Rule
Set's rules, so it holds only `SecAction` and `SecRule` lines that exclude
with `ctl:ruleRemoveTargetById` or `ctl:ruleRemoveById`. A file that cannot be
read or does not parse stops the start, whatever `SWW_WAF_MODE` is. So does a
file that names a number from 900000 to 900999 outside a comment, alone or in
a range. So does a directive that removes or changes rules as the file loads,
such as `SecRuleRemoveById`, since none of the Core Rule Set's rules is loaded
yet. It has no `_FILE` form.
- `SWW_ERROR_BURST_THRESHOLD` (default `30`): the most refusals a client may get
in a minute from a rule file, a trap path or the Core Rule Set, a count or
`off`. The next one bans the client (see "Attack detection" in `SPEC.md`).
## Ban lengths, response and scope
- `SWW_BAN_RESPONSE` (default `403`): `403`, `429` or `close`.
- `SWW_LIMIT_BAN_DURATION` (default `1h`): the ban for a first broken limit. A
duration.
- `SWW_LIMIT_BAN_REPEAT_WINDOW` (default `24h`): the time after a ban ends
within which breaking a limit again lengthens the next ban. A duration.
- `SWW_MAX_BAN_DURATION` (default `7d`): the longest ban for a broken limit; one
that would be longer is permanent. A duration.
- `SWW_ATTACK_BAN_DURATION` (default `7d`): the ban for a first clear sign of
attack. A duration.
- `SWW_BAN_SCOPE_V4_PREFIX` (default `32`): how much a ban on an IPv4 client
covers: the prefix length of its netblock, from 0 to 32.
## Reputation
- `SWW_BLOCKLIST_URLS` (default empty): blocklists to fetch, such as
`https://www.spamhaus.org/drop/drop.txt`. Each an `http` or `https` URL
without a user or a fragment. A URL listed twice is refused.
- `SWW_BLOCKLIST_REFRESH` (default `24h`): how long a list waits after its last
try before it is fetched again. A duration of `1h` or more.
- `SWW_BLOCKLIST_ACTION` (default `deny`): `deny`, `limit:<percent>` or `log`.
- `SWW_DNSBL_ZONES` (default empty): the DNS blocklists to ask, such as
`dnsbl.dronebl.org`. Each a DNS name of at most 189 characters. A Spamhaus
zone carries its key, as in `<key>.xbl.dq.spamhaus.net`. A zone listed twice
is refused, whatever its case or key.
- `SWW_DNSBL_RESOLVER` (default unset): the resolver to ask the zones through,
such as `192.0.2.53` or `[2001:db8::53]:5353`. An IP address with an optional
port, 53 when none is given. Unset, the host's resolver is used.
- `SWW_ABUSEIPDB_KEY` (default unset): the key of your AbuseIPDB account. A
control character in it is refused.
- `SWW_ABUSEIPDB_MIN_SCORE` (default `75`): the least abuse confidence score,
from 0 to 100, that is a hit.
- `SWW_ABUSEIPDB_DAILY_BUDGET` (default `900`): the most checks made in a day, a
whole number above zero. AbuseIPDB's free accounts may make 1,000.
- `SWW_CROWDSEC_LAPI_URL` (default unset): the local API of a CrowdSec engine
you run, such as `http://172.17.0.1:8080`. An `http` or `https` URL without a
user or a fragment; its decision list is at `v1/decisions` under it. Set
without the key, it is refused. So is a decision list URL that is also in
`SWW_BLOCKLIST_URLS`, or that is `SWW_ASN_LIMIT_PERCENT_URL`.
- `SWW_CROWDSEC_LAPI_KEY` (default unset): the key the engine gave for
`smallwebwaf`, as `cscli bouncers add smallwebwaf` prints it. Set without the
URL, it is refused.
- `SWW_REPUTATION_ACTION` (default `limit:25`): `deny`, `limit:<percent>` or
`log`, for DNS blocklist and AbuseIPDB hits.
- `SWW_REPUTATION_CACHE_TTL` (default `24h`): how long a zone's verdict or
AbuseIPDB's score is used. A duration.
- `SWW_REPUTATION_TIMEOUT` (default `2s`): how long a query to a zone or a check
with AbuseIPDB may take. A duration.
## Alerting
- `SWW_ALERT_WEBHOOK_URL` (default unset): the webhook that receives each alert
as a JSON object. An `http` or `https` URL without a user or a fragment.
- `SWW_ALERT_WEBHOOK_HEADERS` (default empty): headers sent with each post, such
as `Authorization:Bearer 0123456789abcdef`. A list of name, `:` and value. A
value cannot hold a comma.
- `SWW_ALERT_SLACK_WEBHOOK_URL` (default unset): the Slack incoming webhook that
receives each alert as a message, checked as the webhook URL is.
- `SWW_ALERT_NTFY_URL` (default unset): the ntfy topic that receives each alert,
as the topic's full URL, such as `https://ntfy.sh/my-alerts`, checked as the
webhook URL is.
- `SWW_ALERT_NTFY_TOKEN` (default unset): an ntfy access token. A control
character in it is refused.
- `SWW_ALERT_EVENTS` (default
`ban,permanent_ban,core_rule_set_match,anomaly,reputation_hit,source_failure,file_error`):
the event types alerts are sent for, from those in [`alerts.md`](alerts.md)
but `summary`. Any other name is refused.
- `SWW_ALERT_COOLDOWN` (default `15m`): how long after an alert is sent its
repeats are held back. A duration or `off`.
- `SWW_ALERT_MAX_PER_HOUR` (default `60`): the most alerts sent in an hour. A
whole number above zero, or `off`.
## Anomaly thresholds ## Anomaly thresholds

## Settings given as files ## Settings given as files

the end. They are checked as the value itself would be. Setting both forms stops
the start, and so does naming a file that cannot be read.
`SWWAF_LOG_REMOTE_TLS_CA_FILE` already holds a file name, so it has no `_FILE`
form.

- `rproxy` reads at most 1 MiB of the body of `discriminator`'s answer, and
answers `502` to a longer one.
## `discriminator`'s answer and `rproxy`'s wait
`SWW_LOOKUP_TIMEOUT` is the longest a question waits on an outside source. Keep
it well under `rproxy`'s `SWRP_TIMEOUT_MS`, as the default is. No question waits
for `SWW_REPUTATION_TIMEOUT`, since the DNS blocklists and AbuseIPDB are asked
in the background (see "Answering in time" under "`discriminator`" in
[`SPEC.md`](../SPEC.md)).
## `rproxy`
`sww rproxy` reads the settings below and no others. They are read once at
start, and an invalid value stops the start. None can be given as a file, since
`rproxy` never touches disk. "`rproxy`" in [`SPEC.md`](../SPEC.md) says what
they do.
A time here is a whole number of milliseconds above zero, such as `2000`.
- `SWRP_WAF_BACKEND` (required, no default): `discriminator`'s URL. An `http` or
`https` URL with a host and an optional port, and nothing more. `rproxy`
speaks HTTP/1.1 to it.
- `SWRP_TIMEOUT_MS` (default `2000`): how long `rproxy` waits for
`discriminator`'s answer, to a question and to a report. A time; never `off`.
- `SWRP_DEFAULT_DISPOSITION` (default `allow`): what is done with a request when
`discriminator` cannot be connected to, does not answer at all, or does not
answer within `SWRP_TIMEOUT_MS`. `allow` passes it to the app, and `deny`
answers `503`. It does not apply to an answer `discriminator` gives, such as
an error.
- `SWRP_MAX_REQUEST_SIZE` (default `100M`): the largest request body. A size or
`off`.
- `SWRP_MAX_RESPONSE_SIZE` (default `1G`): the largest response body. A size or
`off`.
- `SWRP_MAX_REQUEST_TIME_MS` (default `60000`): how long the visitor may take to
send its request line and headers. It then also bounds, from the end of the
headers, the time until the app has been sent the whole request. A time or
`off`.
- `SWRP_MAX_RESPONSE_TIME_MS` (default `1800000`): how long the answer may take,
from the end of the request to its last byte reaching the visitor. A time or
`off`.
- `SWRP_LISTEN_ADDR` (default `:8080`): where `rproxy` listens, such as `:9000`.
- `SWRP_UPSTREAM_URL` (default `http://127.0.0.1:8081`): the app. An `http` or
`https` URL with a host and an optional port, and nothing more.
- `SWRP_TRUSTED_PROXIES` (default `10.0.0.0/8,172.16.0.0/12,192.168.0.0/16`):
the netblocks whose `X-Forwarded-For` is believed. Set but empty, it trusts
nothing. A client outside these netblocks cannot claim another address. Where
other containers reach `rproxy` directly, or visitors on a private network
reach traefik, they can name another address in the header. Narrowing the
setting to traefik's own network closes that gap.
## The image's command
`SWW_COMMAND` (default `rproxy`) chooses what the image runs and what its health
check checks: `rproxy` or `discriminator` (see "Deployment" in
[`SPEC.md`](../SPEC.md)). It cannot be given as a file.
## Where earlier settings went
Nothing reads these names any more:
- `SWW_UPSTREAM_URL` is `SWRP_UPSTREAM_URL`.
- `SWW_TRUSTED_PROXIES` is `SWRP_TRUSTED_PROXIES`.
- `SWW_REQUEST_MAX_BYTES` is `SWRP_MAX_REQUEST_SIZE`.
- `SWW_RESPONSE_MAX_BYTES` is `SWRP_MAX_RESPONSE_SIZE`.
- `SWW_CLIENT_REQUEST_TIMEOUT` and `SWW_UPSTREAM_REQUEST_TIMEOUT` are
`SWRP_MAX_REQUEST_TIME_MS`, in milliseconds.
- `SWW_CLIENT_RESPONSE_TIMEOUT` and `SWW_UPSTREAM_RESPONSE_TIMEOUT` are
`SWRP_MAX_RESPONSE_TIME_MS`, in milliseconds.
- `SWW_CLIENT_IDLE_TIMEOUT` and `SWW_CLIENT_REQUEST_HEADER_MAX_BYTES` have no
setting. `rproxy` closes a kept-open connection idle for 120 seconds, and
takes a request line and headers of at most 32 KiB.

# State files # State files
`smallwebwaf` keeps its state in memory, and a copy of it in five JSON files in The five JSON files in `SWW_STATE_DIR`, and what each holds. "Persistent state"
`SWWAF_STATE_DIR`. The files are meant for people as well: you can read or edit in [`SPEC.md`](../SPEC.md) says how they are written, read and edited. Each has
them at any time, and the running `smallwebwaf` takes the edit in. The a top-level `version` of 1.
requirements they meet are under "Persistent state" in [`SPEC.md`](../SPEC.md).
## The files ## `bans.json`
Each has a top-level `version` of 1. Active and past bans: every ban an admin made, and up to `SWW_MAX_BANS` of those
`discriminator` made. Per entry:
- `bans.json`: active and past bans, up to `SWWAF_MAX_BANS` that `smallwebwaf` - `netblock`, `start` and `expires` (`null` for a permanent ban);
made and every ban you made, indented to be read. Per entry: - `cause`: `attack`, `limit`, `admin` or `crowdsec`;
- the netblock, start and expiry (`null` for permanent); - `reason`: a short reason;
- the cause: `attack`, `limit`, `admin` or `crowdsec`; - `lifted`: when an admin lifted it, if one did;
- a short reason; - `notes`: the notes below.
- when it was lifted, if you lifted it;
- the notes (see [`bans.md`](bans.md)).
- `clients.json`: per client, its minute, hour and day counters and its history
since it was first seen, one client per line, so `grep` shows everything about
one. The history holds:
- the first and last time seen;
- the AS number, AS name and country last looked up, and when;
- total requests, and how many were forwarded and how many refused;
- bytes in each direction;
- responses by status class;
- offences by kind: `limit`, `attack`, `rule_blocked`, `waf_blocked` and
`token_refused`.
Clients that were never banned are kept too, so every client's history An entry an admin adds needs `netblock`, `start` and `expires`; `reason`,
survives a restart. `notes` and `cause` may be left out, and the cause is then `admin`:
- `lookups.json`: GeoJS answers, one per line: the AS number, AS name and ```json
country, when GeoJS was asked and when the answer was last used. {
- `reputation.json`: "version": 1,
- the last good copy of each list fetched from a URL, with when it was last "bans": [

"expires": null,

}
```
"Bans" in [`SPEC.md`](../SPEC.md) says how an edit lifts, keeps or forgets a
ban. The notes:
- `asn`, `as_name` and `country`: the client's, added when the lookup answers
(empty when lookups are off);
- for a broken limit, `kind` (`requests`, `bytes` or `refusals`), `limit`,
`window` and `count`: what the limit was on, the limit, its window and the
count reached;
- `limit_percent` and `limit_percent_setting`: the client's percentage of that
limit and the setting that gave it, when a setting lowered it;
- for a clear sign of attack, `rule_id` and `target`, or `trap_path`;
- `reputation`: the sources the client was on, each with its `source` and, for
AbuseIPDB, its `score`;
- `request`: the request that caused the ban, each text cut to 256 bytes:
- `time`, `method` and `host`;
- `path`, with its query string;
- `status` and `user_agent`;
- `requests` and `refused`: the netblock's requests since it was first seen, and
how many this ban has refused so far, kept up to date while the ban lasts;
- `earlier_bans`: how many earlier bans the netblock had, by cause.
## `clients.json`
Per client, one per line: its minute, hour and day counters, and its history
since it was first seen:
- the first and last time seen;
- the AS number, AS name and country last looked up, and when;
- total requests, and how many were forwarded and how many refused;
- body bytes of its requests, and of the responses it was sent;
- responses by status class;
- offences by kind: `limit`, `attack`, `blocked_by_block_rule` and
`blocked_by_core_rule_set`. A file may also hold `token_refused`, which is
kept, and which nothing adds to.

## Writing full.
- `reputation.json` and `alerts.json`: usually a few MiB or less.
`bans.json` is written `SWWAF_STATE_WRITE_DELAY` after a ban is made, lifted or
made permanent. Every file is written every `SWWAF_STATE_COUNTER_INTERVAL`, and
when `smallwebwaf` stops. Each write goes to a temporary file that then replaces
the file, so a crash leaves the old file or the new one, whole. Before writing a
file, `smallwebwaf` takes in any edit you made to it, so your edit is not
overwritten. A write that fails is logged, raised as a `file_error` alert, and
tried again at the next write. A hard kill loses what changed since the last
write:
- ban changes from the last `SWWAF_STATE_WRITE_DELAY` (10 seconds);
- everything else from the last `SWWAF_STATE_COUNTER_INTERVAL` (15 minutes):
- counts and history, and the counts in ban notes;
- GeoJS answers;
- reputation verdicts and the AbuseIPDB count;
- anomaly counters and alert cooldowns.
## Reading at start
The files are read back. Each client keeps its counts, so a restart gives no one
a fresh allowance. Each ban keeps refusing until it ends. Counter buckets and
cache entries whose time has passed are discarded. A missing file is empty
state. These stop the start, with a message naming the file and the place:
- a file that does not parse, or has another `version`;
- an entry without a field it needs;
- a ban whose `cause` is not `limit`, `attack`, `admin` or `crowdsec`;
- a ban whose `expires` is not after its `start`.
## Editing while it runs
`smallwebwaf` watches the directory and takes in your edit of a file as soon as
you save it. What the file then holds replaces what `smallwebwaf` held for it.
It tells its own writes from yours by comparing the file with what it last read
or wrote. A change it made after you opened the file, such as a new ban, is lost
when you save over it; most editors warn when a file changed on disk while it
was open. An edit with an error that would stop the start does not stop the
running `smallwebwaf`. It keeps what it holds. At the file's next write it
renames your file to `<name>.bad`, writes the file again from memory, and logs
and alerts the file and the place of the error. Mend the `.bad` file and move it
back. A file you remove is written again at its next write.

# The ninth change: on Drupal's paths, some fields skip the rules that refused
# ordinary Drupal requests there. They are the fields where Drupal sends a
# search, a name, a file name or an address. Each exclusion runs with the
# request, before the rules it switches off, so this file is loaded before the
# Core Rule Set's rules. Each comment names a request a rule refused. An
# exclusion on a field of a body applies only when the query has no parameter
# of that name, so it matters only while SWW_WAF_BODY_LIMIT is set.
#
# Four rules read a search or a name as a command or a system file. Each query
# exclusion below removes these four, and only these, from its fields:

# The eighth change: on gitea's paths, some fields skip the rules that refused
