clawbot	1d8d570d5c	AS number and country looked up for every client (closes #95) ... GeoJS's geo.json is asked about every new visitor unless SWWAF_LOOKUP_SOURCE is off. A request waits for its client's first answer only while a country list or SWWAF_ADD_LOOKUP_HEADERS needs it; otherwise the answer reaches the client's history and ban notes when it comes. The AS number and name go beside the country in the request log, history, ban notes, alerts and lookups.json, with metrics by AS number; 64512 counts as unknown. A client's own X-Client-ASN and X-Client-Country never reach the app, whatever the setting says, and make example-app sends no address to GeoJS. Judgement call: AS numbers are written AS64496, as SPEC's settings write them. Judgement call: SWWAF_LOOKUP_TIMEOUT is added, default 1s, and cannot be off. Model: opus-5-5	2026-10-07 06:34:35 +00:00
clawbot	74bdc6a449	Leave SWWAF_RATE_LIMIT_EXEMPT_PATHS out of the request rate limits (closes #77) ... A request is neither counted nor refused by the request rate limits when its path as sent, the path the app receives, not percent-decoded, starts with one of the comma-separated prefixes in SWWAF_RATE_LIMIT_EXEMPT_PATHS, so /%61ssets/x is not under /assets/. A request whose decoded path contains .. or a backslash, or whose path as sent holds an encoded slash, is never exempt, since an app may act on it as a path outside every prefix, such as /assets/..%2Flogin as /login. The static lists, bans and the country lists still apply, and its log line has no counts. The setting is empty by default, and a prefix that does not start with / stops the start. README.md documents it. Model: opus-5-5	2026-10-06 18:47:13 +02:00
clawbot	73ca94f850	Ban the netblock of a client that breaks a rate limit, in memory (closes #18) ... A request over a rate limit is refused with SWWAF_BAN_RESPONSE and bans the client's netblock: an hour at first, three times the last ban when broken again within a day of its end, permanent past seven days. The ban ledger in internal/bans is checked after the static lists and before the lookup, and the requests it refuses are not counted. A ban resets the client's counters and carries notes holding the request that broke the limit, as SPEC.md now says. At most SWWAF_MAX_BANS are held. SWWAF_BAN_RESPONSE also answers SWWAF_DENY_NETS and the country lists. Judgement call: the six ban settings cannot be off. Judgement call: a permanent ban's ban_expires is "permanent".

clawbot	f51459fbfe	Per-client request rate limits over a minute, an hour and a day (closes #43) ... Each client, one IPv4 address or one IPv6 /64, is counted in two buckets per window, the earlier weighted by how much of it the window covers; at most 20,000 clients are kept, least recently seen dropped first. A request over SWWAF_RATE_LIMIT_PER_MINUTE, _HOUR or _DAY (1000, 10000, 50000, or off) gets 429 before reaching the app. Refused requests count, 413s included. A clock set back over a second behind a bucket's start restarts that window. The log line gains limit_hit and the action rate_limited. Deviation from SPEC.md, per the issue: the 20,000 bound and /64 are fixed. Judgement call: golang-lru/v2 holds the table; httprate does not count refused requests. Deviation: go.mod and go.sum hand-written; no make target tidies them. Model: opus-5-5	2026-10-04 04:24:34 +02:00
