ureq 3.4.1 (#1194, "Fix timeout budgets restarting and applying to later
phases") made timeout_recv_response bound only the response HEADERS and
turned timeout_recv_body into an ABSOLUTE total-body deadline. The online
key-service POST set recv_response only, so under 3.4.2 the reply body read
had NO deadline at all — a server that sent headers then stalled mid-reply
would hang the key request forever.
The /decode reply is a small JSON key answer that arrives in one read (a
few hundred bytes; the 1 MiB cap is a defensive anti-OOM ceiling, not an
expected size), so this is a fine total-cap case, not a large-body slow-link
download: no rolling-idle connector is warranted. Set timeout_recv_body to
the same TIMEOUT_SECS total ceiling so the POST can never hang forever.
Regression guard the_reply_body_read_is_bounded_not_only_the_headers asserts
recv_body is now set. Full suite + precommit (fmt/clippy/deny/tests) green.
online.rs:
- validate_keyserver_url/resolve_and_guard now reject any non-https:// scheme
as a Config fault, so a cleartext misconfig is caught ONCE at config time
instead of failing every rip via query()'s runtime https check.
- is_blocked_ip: add 198.18.0.0/15 (RFC 2544 benchmarking) and 192.0.0.0/24
(RFC 6890 IETF protocol assignments, incl. 192.0.0.170/171) to the SSRF guard.
- DNS in-flight cap is now PER HOST, not process-global, so black-holed lookups
to one dead keyserver can't starve resolution of a healthy different keyserver.
- reject a non-empty, non-":port" tail after a bracketed IPv6 authority
(e.g. https://[::1]extra/) instead of silently dropping it.
keydb.rs / keydb_format.rs:
- MAX_KEYDB_BYTES defined once in keydb_format and re-used by keydb.rs.
- CacheEntry::is_settled falls back to inode identity + stamped_at age when the
mtime is absent (mtime-less FS) or in the future (clock skew), so the ~62 MiB
keydb no longer re-parses on every lookup.
- save()'s entry-count guard counts DK/PK/HC/HC2 rows via the real parsers
(is_parseable_entry_line), so a prefixed-but-malformed row can't pass entries>0.
Tests added for each fix.
Several tests asserted only key[0] (the first byte), which a byte-transposition bug could pass — assert the full 16-byte key everywhere, including a KAT that recomputes the expected VUK-derived keys directly. test_parse_disc_entry used identical all-zero placeholders for M/I/V/U, which couldn't catch a field mix-up; give each field a distinct byte pattern and assert every field.
Docs: keydb-format.md claimed DiscEntry::title was genuinely unused dead code, but it's read by to_keydb_cfg and the redacting Debug impl — correct the comment to only list empty/find_vuk as truly unused. Also cross-reference the two independent MAX_KEYDB_BYTES constants (keydb.rs's decompression cap and keydb_format.rs's on-disk load cap) so they're kept in sync, and bump Cargo.lock's version metadata.
CI/lint hardening since v1.6.14: clippy on stable with the MSRV single-sourced
from Cargo.toml, cargo-deny dependency-audit gate with first-party git sources
allowed (#15), and audience-based comment-guard (#17). No library code changes.
