From 529f206d33c35bcdfd6911aa37d604ff5338495b Mon Sep 17 00:00:00 2001 From: mmmray <142015632+mmmray@users.noreply.github.com> Date: Sun, 21 Jul 2024 02:29:50 +0200 Subject: [PATCH] Fix serverside TLS support of SplitHTTP H1/H2 (#3567) Fix #3566 Also update testsuite so that all tests read and write some data. Opening a connection is not enough to trigger connection errors, because the connection is so lazy. --- transport/internet/splithttp/hub.go | 24 ++++--- .../internet/splithttp/splithttp_test.go | 64 +++++++++++++++++-- 2 files changed, 73 insertions(+), 15 deletions(-) diff --git a/transport/internet/splithttp/hub.go b/transport/internet/splithttp/hub.go index 1ce8da6b..d4579bc7 100644 --- a/transport/internet/splithttp/hub.go +++ b/transport/internet/splithttp/hub.go @@ -269,7 +269,6 @@ func ListenSH(ctx context.Context, address net.Address, port net.Port, streamSet tlsConfig := getTLSConfig(streamSettings) l.isH3 = len(tlsConfig.NextProtos) == 1 && tlsConfig.NextProtos[0] == "h3" - if port == net.Port(0) { // unix listener, err = internet.ListenSystem(ctx, &net.UnixAddr{ Name: address.Domain(), @@ -285,9 +284,9 @@ func ListenSH(ctx context.Context, address net.Address, port net.Port, streamSet Port: int(port), }, streamSettings.SocketSettings) if err != nil { - return nil, errors.New("failed to listen UDP(for SH3) on ", address, ":", port).Base(err) + return nil, errors.New("failed to listen UDP(for SH3) on ", address, ":", port).Base(err) } - h3listener, err := quic.ListenEarly(Conn,tlsConfig, nil) + h3listener, err := quic.ListenEarly(Conn, tlsConfig, nil) if err != nil { return nil, errors.New("failed to listen QUIC(for SH3) on ", address, ":", port).Base(err) } @@ -314,7 +313,6 @@ func ListenSH(ctx context.Context, address net.Address, port net.Port, streamSet if err != nil { return nil, errors.New("failed to listen TCP(for SH) on ", address, ":", port).Base(err) } - l.listener = listener errors.LogInfo(ctx, "listening TCP(for SH) on ", address, ":", port) // h2cHandler can handle both plaintext HTTP/1.1 and h2c @@ -324,18 +322,24 @@ func ListenSH(ctx context.Context, address net.Address, port net.Port, streamSet ReadHeaderTimeout: time.Second * 4, MaxHeaderBytes: 8192, } + } + + // tcp/unix (h1/h2) + if listener != nil { + if config := v2tls.ConfigFromStreamSettings(streamSettings);
