sneak 8c5762b44f Core Rule Set: Drupal's ordinary requests pass by default (closes #236)
check / check (push) Successful in 6m41s
Details 
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
Details 
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
Details 
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
Details 
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
Details 
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
Details 
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
Details 
`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
Details 
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.

clawbot 42e06bf298 Quiet the update-alternatives man page warnings in the image build (closes #222) (#226)
check / check (push) Successful in 5m24s
Details 
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.

### 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).

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

listed twice is refused. such as `AS14061:50` or `cn:25`. It takes the place of the percentage
- `SWWAF_COUNTRY_LIMIT_PERCENT` (default empty): the same by country, such as `SWW_TAG_LIMIT_PERCENT` gives their `asn=` or `country=` tag. An AS number or
`cn:25,ru:50`. country listed twice is refused.
- `SWWAF_ASN_BYTES_PERCENT` and `SWWAF_COUNTRY_BYTES_PERCENT` (default empty): - `SWW_UNKNOWN_LIMIT_PERCENT` (default `100`): the percentage for a client the
the same, for the byte limits alone.
- `SWWAF_UNKNOWN_LIMIT_PERCENT` (default `100`): the percentage for a client the
lookup cannot place. lookup cannot place.
- `SWWAF_ASN_LIMIT_PERCENT_URL` (default unset): the `http` or `https` URL of a - `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 text file with one AS number and percentage on each line, such as
`AS64496:50`. A URL that is also in `SWWAF_BLOCKLIST_URLS` is refused. `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.

# 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.
#
# Six rules read a search or a name as a command or a system file. Each query
# exclusion below removes these six, and only these, from its fields:

# 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.
# gitea's searches of code, of issues and pull requests, and of commits send the
