- selector.go: Select() now only returns methods the client actually offered,
defaulting to MethodNoAcceptable (0xFF) when no mutually-supported method
exists. Prevents protocol desync when authenticator is set but client
doesn't offer UserPass. (#1, #2)
- connect.go: CONNECT success reply now carries the outbound connection's
actual local address as BND.ADDR per RFC 1928 §6, instead of 0.0.0.0:0. (#4)
- udp.go: UDP ASSOCIATE now verifies the upstream chain is reachable before
sending Success to the client; on failure sends a proper Failure reply.
Also adds safe type assertions for net.TCPAddr and net.UDPAddr to prevent
panics on wrapped connections, and returns errors on DNS resolution failure
instead of silently dropping datagrams. (#5, #1, #2, #3)
Move SetDefaultTLSConfig before register(cfg) in loader.go so
ParseService can access it when building handlers. Also add a
defensive nil check in socks5 serverSelector.Select() for
MethodTLS to prevent future ordering regressions.
Root cause: in selector.go, Select() tried to read ClientHello
via TLSConfig.GetConfigForClient but s.TLSConfig was nil because
register(cfg) -> ParseService -> handler Init ran before
SetDefaultTLSConfig was called from loader.go.
