0.6.5

A build-portability and reliability patch on the 0.6 line: MSE now works without libcrypto RC4, and three platform bugs that broke Windows outbound traffic are fixed.

Added

• A built-in RC4 stream cipher (Peer.MSE.RC4), selected automatically when the linked libcrypto does not expose RC4. OpenSSL 3 moved RC4 into the optional legacy provider and the Windows ERTS ships no legacy module, so :crypto omits :rc4 there — and because the whole MSE handshake is RC4-encrypted, including the exchange that selects a plaintext stream, such a node could not speak MSE at all and every peer dial failed. config :elixir_torrent, :mse_rc4 accepts :auto (default), :crypto, :pure or :disabled.

Fixed

• Tracker announces now choose their source address by asking the kernel which local address routes to the destination, instead of taking one from Acceptor.all_global_ips/0. Windows enforces the strong host model and refuses a bind whose address does not belong to the routing interface, so with a VPN, a second NIC or tethering every announce failed with :eaddrnotavail. BEP 7 is unchanged where a routable global address exists; an announce refused for the bind is retried once unbound.
• Magnet.Fetcher.finalize_piece_attempt/1 no longer raises FunctionClauseError on a non-retryable piece attempt, which previously took down the entire magnet fetch instead of that one attempt. :econnreset and :econnaborted — how a departing peer is reported on Windows — are now treated as retryable.
• The DHT IPv4 socket logged bind=<primary ip> while actually being bound to 0.0.0.0.

Changed

• The test suite now runs on Windows. It previously failed before the first test on a /dev/null path, and then on localhost resolution: the suite forbids DNS on the wire, Unix answers localhost from /etc/hosts, and Windows ships that line commented out. Three platform assumptions in tests and three TOCTOU races were fixed alongside.
