clawbot 866b948ec0 Gitea setup: Core Rule Set blocks attacks, not ordinary Gitea traffic (closes #198)
check / check (push) Successful in 3m16s
Details 
The Gitea setup runs the Core Rule Set in block mode. Rules that refused
ordinary Gitea requests are switched off only where they misfired:

- deploy/gitea/crs-exclusions.conf, loaded through the new setting
  SWWAF_CORE_RULE_SET_EXCLUSIONS_FILE before the Core Rule Set's rules,
  covers Gitea's search, file-name and branch-name fields, Referer, file
  paths, API attachment names and Actions artifact uploads;
- smallwebwaf's defaults gain a seventh change: the registry upload
  path's from parameter skips 932260.

A file that cannot be read, does not parse or names an id from 900000
to 900999 stops servewaf at start, in every mode. internal/waf's tests
and script/gitea-setup send the recorded requests in
internal/waf/testdata/gitea-requests.txt and three attacks.

Model: opus-5-5

### Request tags
Each request gets tags from what `discriminator` knows of its client, written in
the `tags` field of its log line:
- `asn=<number>` and `country=<code>`, from the lookup;
- one tag per list of `SWW_TAG_LISTS` that holds the client, such as `torexit`
or `vpn=mullvad`;
- `crowdsec`, `dnsbl=<zone>` and `abuseipdb`, when that reputation source lists
the client;
- `exploitsignature`, when a rule file or the Core Rule Set matched the request;
- `asn=<number>` and `prefix=<netblock>`, from a routewatch instance, while
`SWW_ROUTEWATCH_URL` is set.
`SWW_TAG_DENY` refuses requests by tag, and `SWW_TAG_LIMIT_PERCENT` lowers a
client's limits by tag. See "Request tags" in [`SPEC.md`](SPEC.md).
### Attack detection
- The Core Rule Set reads the method, the URL with its query string, and the
headers of every request, and no body unless `SWW_WAF_BODY_LIMIT` is set. In
headers of every request, and no body unless `SWWAF_WAF_BODY_LIMIT` is set. In
front of a code forge, bodies carry what people write and publish, which the
rules take for attacks.
- `smallwebwaf` changes the Core Rule Set in nine ways so that ordinary requests
get through to a code forge and to Drupal. On a code forge they include git
over HTTP and sign-in through Git Credential Manager. On gitea's own paths,
its searches, file names and branch names get through too. On Drupal's own
paths, its searches, names and the page to return to do. No setting undoes the
changes; "Attack detection" in [`SPEC.md`](SPEC.md) lists them.
- These apps work out of the box at the default settings. The Core Rule Set lets
through the ordinary requests recorded from each of them:
- gitea;
- Drupal.
- `SWW_CORE_RULE_SET_EXCLUSIONS_FILE` switches single rules off for an app's own
fields or paths.
- `smallwebwaf` changes the Core Rule Set in seven ways so that it lets ordinary
requests to a code forge through, such as git over HTTP and sign-in through
Git Credential Manager. No setting undoes them; "Attack detection" in
[`SPEC.md`](SPEC.md) lists them.
- `SWWAF_CORE_RULE_SET_EXCLUSIONS_FILE` switches single rules off for an app's
own fields or paths. gitea's exclusions, in
`deploy/gitea/crs-exclusions.conf`, let its searches, file names and branch
names through.
- Rule files are plain text, one rule to a line, edited by hand and read again

`servewaf` keeps everything in memory, and the five JSON files in

# smallwebwaf in front of gitea
`deploy/gitea/compose.yaml` runs gitea behind traefik, with `rproxy` and
`servewaf` in front of it. This document says what that setup sets and why, and
what the defaults would do without it. [`SPEC.md`](../SPEC.md) says how
`smallwebwaf` behaves.
## The setup
Four containers share one Docker network, the shared network:
- traefik, which routes the site's HTTPS requests to `rproxy`, and redirects
plain HTTP to HTTPS;
- `rproxy`, in front of gitea;
- gitea 1.27.3, as its image comes;
- `servewaf`, with a volume for its state files, and with
`deploy/gitea/crs-exclusions.conf` mounted read-only.
To start it:
1. In `deploy/gitea/compose.yaml`, replace `git.example.org` with the site's
host name.
2. Replace each `10.99.0` with the first three numbers of a `/24` subnet that no
other network on the host uses. The `/24` must lie inside `10.0.0.0/8`,
`172.16.0.0/12` or `192.168.0.0/16`, because `rproxy` believes
`X-Forwarded-For` only from those by default. Replace each `fd10:99` with the
first two hextets of an unused `/64` subnet whose third and fourth hextets
are 0, as in `fd10:99::/64`.
3. Set `SMALLWEBWAF_IMAGE` to the `smallwebwaf` image, named by digest.
4. Set `GITEA_SECRET_KEY` to the output of
`docker run --rm <gitea's image> gitea generate secret SECRET_KEY`, with
gitea's image as `deploy/gitea/compose.yaml` names it. Do this once per
install, and keep the key.
5. Run `docker compose up --detach` in `deploy/gitea`, with
`crs-exclusions.conf` beside `compose.yaml`.
6. Make gitea's first user with `gitea admin user create`, in gitea's container,
as the user `git`.
Sign-up is off: accounts are made with `gitea admin user create`. gitea starts
at its defaults, with SQLite. traefik answers with a certificate it made itself
until you add a certificate resolver, as for your other sites. SSH to gitea does
not pass through `smallwebwaf`; publish gitea's SSH port yourself if you use it.
`make gitea-setup` checks the setup. It builds the image, brings the setup up
under a name of its own, and checks:
- that a page load, a push and a clone sent through traefik pass through
`rproxy`, and that `servewaf` checks them;
- that gitea logs the visitor's address, not `rproxy`'s;
- that a request from a container on the shared network skips the checks;
- that the Core Rule Set refuses none of the ordinary gitea requests in
`internal/waf/testdata/gitea-requests.txt`, sent by a signed-in user;
- that it refuses none of the API calls with JSON bodies;
- that it refuses no fetch;
- that it refuses SQL injection, path traversal and script injection in a query
string;
- that with `servewaf` stopped, gitea still answers through `rproxy`.
## Uploads and downloads
An upload is a request:
- a git push;
- an LFS object;
- a container image layer;
- a package file;
- a release attachment.
The setup lets an upload of up to 2 GiB, sent in up to 30 minutes, through:
- `SWRP_MAX_REQUEST_SIZE` is `2G`. At the default, an upload over 100 MiB is cut
off.
- `SWRP_MAX_REQUEST_TIME_MS` is `1800000`, 30 minutes. At the default, an upload
that takes over 60 seconds is cut off.
- traefik's `readTimeout` is 30 minutes. traefik's own default of 60 seconds for
a whole request would cut off an upload first.
A clone or a download is a response:
- `SWRP_MAX_RESPONSE_TIME_MS` is `900000`, 15 minutes, half the default. A clone
or download that takes longer is cut off.
- `SWRP_MAX_RESPONSE_SIZE` stays at its default, 1 GiB. A repository whose clone
is larger needs it raised.
The byte limits stay at their defaults: no minute limit, 50 GiB an hour and 100
GiB a day.
## The checks
The Core Rule Set runs in `block` mode, the default, with gitea's exclusions
(see "The Core Rule Set's exclusions" below).
Every other check stays at its default. A client may make 120 requests a minute,
1,500 an hour and 6,000 a day. Archive downloads and blame and history pages are
what scrapers hammer, and these limits do most of the work there.
## The shared network
Containers on the shared network skip `servewaf`'s checks:
- The shared network's subnets are `10.99.0.0/24` and `fd10:99::/64`. Docker
gives its containers addresses in the upper half of each, `10.99.0.128/25` and
`fd10:99:0:0:8000::/65`, which `SWWAF_ALLOW_NETS` names.
- traefik is known on the shared network by the site's host name. So a container
there that asks for the site reaches traefik from its own address. An
automation fleet in such a container skips the checks.
- Each subnet's gateway, `10.99.0.1` and `fd10:99::1`, is the host's own address
on it. Requests docker passes on from a published port can come from the
gateway, so the gateways are left out of `SWWAF_ALLOW_NETS`. The network has
IPv6, so a visitor over IPv6 reaches traefik from its own address, and
`servewaf` checks it as itself.
- A container on the shared network that asks for the site at the host's public
address arrives from the gateway. It is checked like any visitor.
- A fleet on another host can have its address added to `SWWAF_ALLOW_NETS`.
Without that, it is counted like any client.
- traefik replaces the `X-Forwarded-For` a visitor sends, by default. Keep it
so: otherwise a visitor could name an address on the shared network, and skip
the checks.
- Anything on the shared network can reach gitea and `servewaf` around `rproxy`.
Put only containers you trust on it.
## gitea's settings
- `REVERSE_PROXY_TRUSTED_PROXIES` names `rproxy`'s fixed addresses, `10.99.0.2`
and `fd10:99::2`. gitea then takes each visitor's address from the `X-Real-Ip`
header, which traefik sets and `rproxy` passes on. Without it, gitea logs
every visitor as `rproxy`.
- `INSTALL_LOCK` is `true`, as "The setup" above says.
## Methods
`rproxy` passes on only these methods: `GET`, `HEAD`, `POST`, `OPTIONS`, `PUT`,
`DELETE`, `PATCH` and `QUERY`. gitea 1.27.3 needs no other. Its routes use:
- pages and the API: `GET`, `HEAD`, `POST`, `PUT`, `PATCH` and `DELETE`;
- git's push, clone and fetch over HTTP: `GET`, `POST` and `OPTIONS`;
- LFS: `GET`, `POST` and `PUT`;
- the container registry and the other package registries: `GET`, `HEAD`,
`POST`, `PUT`, `PATCH` and `DELETE`;
- Actions runners: `POST`.
## The log
`rproxy` and `servewaf` write each query string to the log whole. A token sent
in the query string, as `?token=`, is then in the log. Send it in the
`Authorization` header instead.
## Actions runners
A runner on the shared network skips the checks. One on another host is counted
like any client. A runner older than version 0.4 (April 2026) asks for work
every 2 seconds, 1,800 requests an hour. While it runs a job, it reports the
job's log and state every second instead, two requests a second.
So one idle runner makes 1,800 requests an hour, more than the hour limit of
1,500. A busy one, at two requests a second, passes the minute limit of 120
within two minutes. Its address is then banned, its running jobs fail, and each
repeat within a day makes the ban longer. Newer runners ask for work less often.
Put the runners' addresses in `SWWAF_RATE_LIMIT_EXEMPT_NETS`.
## The Core Rule Set's exclusions
`deploy/gitea/crs-exclusions.conf` switches single Core Rule Set rules off where
they refused ordinary gitea requests. `servewaf` loads it from
`SWWAF_CORE_RULE_SET_EXCLUSIONS_FILE`, before the Core Rule Set's rules. Each
exclusion covers one rule, in these places only:
- `q`, the text of every search;
- the query parameters that hold a file name: `file`, `path`, `template`, `body`
and `redirect_to`;
- the query parameters that hold a branch or tag name: `name`, `tag`,
`rule_name` and `refSubUrl`;
- `Referer`, on a page opened from search results or from a file's page;
- the path of a file's page, raw file, blame, history and edit page, and of the
API's call for its contents;
- `name`, the file name of an attachment uploaded through the API;
- the header `Content-Range` of an Actions artifact upload.
gitea reads these as text to search for, as names in a repository, or, for
`Content-Range`, as the part of a file an upload carries. It never runs them as
SQL, a command or a page's script. So an attack that only the excluded rules
would catch there reaches gitea and does nothing. Every other field and path
keeps every rule.
To add an exclusion for a request the Core Rule Set refuses:
1. Find the request in `servewaf`'s log. Its line gives the path and query, and
names the rules in `waf_rule_ids`.
2. For each rule, add a line with `ctl:ruleRemoveTargetById` for the field it
matched. For a field on every path, copy one of the file's `SecAction` lines.
For some paths only, copy one of its `SecRule REQUEST_FILENAME` lines. Give
it a new id. An id from 900000 to 900999 stops the start.
3. Above it, write a one-line comment naming the request it refused.
4. Add the request to `internal/waf/testdata/gitea-requests.txt`, and run
`make check`.
5. Restart `servewaf`.
The Core Rule Set still refuses the page of a file in a directory named `...`,
which reads as path traversal.
With `SWWAF_WAF_BODY_LIMIT` set, it also refuses issue text, comments, wiki
pages and files saved in the web editor that hold shell commands or code.
`make gitea-requests` runs gitea behind `rproxy` and `servewaf` at the defaults,
without these exclusions. It reports each request the Core Rule Set refuses
there.

- `SWW_RATE_LIMIT_PER_HOUR` (default `1500`): the most requests a client may
person opening two gitea pages at once with an empty cache, up to 60 files
each.
- `SWWAF_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
person reading code in gitea 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.
- `SWWAF_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.
- `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.

the runners' addresses in `SWW_RATE_LIMIT_EXEMPT_NETS`. Do the same for a
- An Actions runner asks gitea for work all day and can pass the limits. Put the
runners' addresses in `SWWAF_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/`.
- `SWWAF_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.
- `SWWAF_BYTES_LIMIT_PER_MINUTE` (default `off`), `SWWAF_BYTES_LIMIT_PER_HOUR`
(default `50G`) and `SWWAF_BYTES_LIMIT_PER_DAY` (default `100G`): the most
bytes counted for a client in each window. A size or `off`.
- `SWWAF_BYTES_COUNT` (default `both`): which body bytes the byte limits count:
`response`, `request` or `both`.
## Lookup of AS number and country
- `SWW_LOOKUP_SOURCE` (default `geojs`): `geojs`, `file` or `off`. `off` stops
- `SWWAF_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`;
- the two country lists;
- `SWWAF_ADD_LOOKUP_HEADERS`;
- the four biased threshold lists and `SWWAF_ASN_LIMIT_PERCENT_URL`;
- `SWWAF_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
- `SWWAF_LOOKUP_DB_PATH` (default empty): the IPinfo Lite database file, in its
`.mmdb` form, for `SWWAF_LOOKUP_SOURCE=file`.
- `SWWAF_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
- `SWWAF_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
## Country lists
- `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.
- `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 country on both lists
stops the start.
## 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
- `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.
- `SWWAF_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
- `SWWAF_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.
`AS64496:50`. A URL that is also in `SWWAF_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
- `SWWAF_RULES_DIR` (default `/etc/smallwebwaf/rules.d`): the directory of the
rule files.
- `SWWAF_RULES_ENABLED` (default `true`): `false` reads no rule file.
- `SWWAF_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,

`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
- `SWWAF_WAF_EXEMPT_PATHS` (default empty): path prefixes the Core Rule Set does

- `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
- `SWWAF_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)).
- `SWWAF_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`).

that would be longer is permanent. A duration.
- `SWW_ATTACK_BAN_DURATION` (default `7d`): the ban for a first clear sign of

# 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:
