I1 becomes a DNS query to a random popular domain (A/AAAA) instead of the
shared icloud.com response every key carried. The format sticks to tags both
the kernel module and amneziawg-go accept and is checked before awg1.conf is
written: a bad I1 fails the whole awg-quick up. With KEEP_DATA=y the old I1
is kept, or generated if missing — the server never checks it, old keys keep
their own.
MTU is picked from 1320–1376 (AWG_MTU overrides) and kept on reinstall.
awg-ctrl now reads MTU from awg1.conf for vpn:// keys instead of a constant.

The torrent flag was read inside loops over users rows (users/stats,
peers, metrics) and each read queried the config table. SQLite has a
single connection here, so the nested query waited for it forever: the
first stats request or Prometheus scrape locked awg-ctrl for good, and
the panel showed no users and timed out.
- the block setting is kept in memory (loaded at start, updated on
save), so the flag never touches the database
- the set of flagged IPs is taken once before the query, not per row
- regression test: collectMetrics must finish with users in the table
Panel: a 401 from the panel itself (its JWT not accepted) now returns to
the login screen; a 401 relayed from a node's awg-ctrl does not.
- awg-ctrl: optional nft table awg_torrent (GET/PUT /api/torrent, off by
default). A connection is judged by its first packets, like Xray's
sniffing: DHT, UDP trackers, uTP SYN, and with @ih support the plain
TCP handshake and HTTP announce. A match marks the connection in
conntrack and drops it whole; without @ih only the UDP part is used
- devices that tried are kept in a 10-minute set and flagged as
"torrent" in user and device stats; with shaping on they sit in the
background class while the flag lasts
- metrics: awg_torrent_block_enabled/active, awg_torrent_blocked_total,
awg_torrent_devices and per-peer awg_peer_torrent
- panel: "Торренты" section in server settings, "торренты" chip on users
and devices; Save sends only what changed
The differential bench (GEN 2 and 3.1, with I1, S4=0, upgrade with a 3.x
module) now shows the Go awg-ctrl identical to the TS one. The only real
difference it found: host.cpu was a Go map, so its keys came out sorted
instead of in /proc/stat order.
- tools/diffbench/compare.mjs: decodes vpn:// (Node and Go zlib differ), masks
live host numbers, Express dev-mode stack traces, temp file names and the
order of calls from concurrent background work
- tools/diffbench/local.sh: the same run without Docker, stubs only on the
run's own PATH (for disposable machines)
- run.sh: wait for the background shaping apply before stopping the service,
otherwise the stub log is cut short
- internal/jsjson: JSON.stringify-compatible encoder and order-preserving decoder,
tested against fixtures produced by Node itself
- internal/ctrl: awg-ctrl in Go (params, vpn:// keys, users, peers, sync, 3.1
upgrade, CAKE shaping, metrics, monitor job, Express-compatible HTTP layer)
- internal/iauth, internal/logx: internal Ed25519 tokens and logging
- tools/diffbench: Docker bench with stubbed awg/ip/tc/nft that runs one scenario
against the TS and Go implementations for comparison
