### In front of gitea
gitea behind traefik, set up for a code forge:
- the upload limits raised, in size and in time;
- the response size limit and the byte limits raised, for clones over 1 GiB;
- the Actions runners exempt from counting;
- the default request limits kept, since they already leave room for API
clients.
`traefik` is the network traefik is on, made outside this file.

### 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.

# 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 `rproxy` and
`servewaf`, and sends through them 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 1 GiB unless the
repository is large or the link slow. A repository whose clone is larger than
1 GiB needs `SWRP_MAX_RESPONSE_SIZE` raised, and the byte limits with it
("Byte limits, per client" in `SPEC.md`).
- A push is a request, and so is every other upload:
- a git push;
- an LFS object;
- a container image layer;
- a package file;
- a release attachment.
At the defaults, an upload larger than 100 MiB or taking more than 60
seconds is cut off ("`rproxy`'s limits" in `SPEC.md`). A gitea that takes
large uploads needs `SWRP_MAX_REQUEST_SIZE` and `SWRP_MAX_REQUEST_TIME_MS`
raised to fit.
- 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. While it runs a job, it reports the job's log and state
every second instead, two requests a second. So one runner busy all day sends
120 requests a minute and 172,800 a day, under the request limits. Two such
runners on one address, each busy all day, make 345,600 and pass the day limit
of 300,000. Three busy at once make 21,600 an hour and pass the hour limit of
20,000. Five busy at once make 600 a minute and pass the minute limit of 500.
Their address is then banned, their 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`.
## 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 ("Bans" in `SPEC.md` says what it counts
toward). 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. A search term is a query parameter, which the Core
Rule Set checks against its lists of system files and commands (see the fourth
change 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, such as `python3` or `ssh key`, or has
one right after a `/` in its first word, such as `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 query parameter holding 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. A listing sends it when
it asks for its entries' last commits in a second request. It does so 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 too in the ten query parameters that
930120, 932160 and 932260 do not check (see the fourth change 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, for a visitor who opens 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, these are refused:
- the page of the file;
- its raw file;
- its history and its blame;
- its edit page.
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 starts with an entry on the list of commands. It is refused too when the
image's name after the owner starts with one. 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 ("Attack detection" in `SPEC.md`).
### 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. The error burst ("Attack detection" in `SPEC.md`) bans it after more
than 30 such refusals from its address in a minute, as when many jobs upload at
once. `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 for a visitor who opens 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.

countries whose clients get through, such as `us,de`. A country on both lists
## Request tags stops the start.
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 ## Biased thresholds
- `SWW_ASN_BYTES_PERCENT` and `SWW_COUNTRY_BYTES_PERCENT` (default empty): a - `SWWAF_ASN_LIMIT_PERCENT` (default empty): a list of AS numbers, each with `:`

`SWW_TAG_LIMIT_PERCENT` gives their `asn=` or `country=` tag. An AS number or - `SWWAF_COUNTRY_LIMIT_PERCENT` (default empty): the same by country, such as
country listed twice is refused. `cn:25,ru:50`.
- `SWW_UNKNOWN_LIMIT_PERCENT` (default `100`): the percentage for a client the - `SWWAF_ASN_BYTES_PERCENT` and `SWWAF_COUNTRY_BYTES_PERCENT` (default empty):

lookup cannot place. 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 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`. `AS64496:50`. A URL that is also in `SWWAF_BLOCKLIST_URLS` is refused.
A URL that is also in `SWW_BLOCKLIST_URLS` is refused.

# 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:
# 930120: .htaccess
# 932120: powershell
# 932250: ls -la
# 932260: python3
# Two more misfire on destination, the address of a page of results, so
# destination alone skips them:
# 932230: ls -la
# 932235: python3

# The eighth change: on gitea's paths, some fields skip the rules that refused
# ordinary gitea requests there. They are the fields where gitea sends a search,
# a file name or a branch name. Each exclusion runs with the request, before the
# rules it switches off, those of phase 1 included, so this file is loaded before
# the Core Rule Set's rules. Each comment names a request the rule refused.
