Tor stopped serving v2 onion services in October 2021; lnd should not produce v2 addresses anymore, but it must still verify signatures on and re-broadcast peer NodeAnnouncement messages that carry v2 entries. Stop accepting v2 as configuration input (lncfg), strip the legacy `--tor.v2` flag from the sample config, and remove the `tor.OnionHostToFakeIP` helper. Operator entry points (`--externalip`, `--listen`, `lncli connect`, `lncli wtclient towers add`) fail fast on a v2 `.onion` string, so upgrading nodes must remove any v2 entry from `lnd.conf` before lnd will start. Filter persisted v2 state before use without rewriting on-disk records: the self-announcement builder strips any v2 entry inherited from the stored self-node; the watchtower client drops v2 entries from each persisted tower's address list (skipping the tower entirely if no non-v2 address remains); the autopilot connector, graph bootstrapper, and static-channel backup restore paths skip v2 entries before attempting outbound dials. Restrict the Tor controller's ADD_ONION path to v3 keys, including the encrypted on-disk legacy-key fallback. For inbound announcements, keep the wire codec wire-faithful: `lnwire.WriteOnionAddr`, `graph/db.encodeOnionAddr`, and the matching decoders round-trip v2 bytes so `DataToSign` reproduces the bytes the remote peer signed, signature validation succeeds, and the announcement is persisted to the graph DB and re-broadcast across restarts byte-for- byte. RPC surfaces continue to expose the full address set so external tools can independently reproduce and verify the signed bytes. Add a netann regression test that signs a [v3, v2, ipv4] announcement, round-trips it through Encode/Decode, verifies the signature, and confirms the resulting models.Node preserves the v2 entry. Add a graph bootstrapper test asserting v2 entries are skipped while v3 and plain TCP entries on the same node still surface as bootstrap candidates. |
