Functions

func GetServerTLSConfig

func GetServerTLSConfig(tlsCertFile, tlsKeyFile, tlsMinVersion string, tlsCipherSuites []string) (*tls.Config, error)

GetServerTLSConfig returns TLS config for the server.

func GetTCPNetwork

func GetTCPNetwork() string

GetTCPNetwork returns current tcp network.

func GetUDPNetwork

func GetUDPNetwork() string

GetUDPNetwork returns current udp network.

func IsTrivialNetworkError

func IsTrivialNetworkError(err error) bool

IsTrivialNetworkError returns true if the err can be ignored during logging.

func ParseTLSVersion

func ParseTLSVersion(s string) (uint16, error)

ParseTLSVersion returns tls version from the given string s.

func TCP6Enabled

func TCP6Enabled() bool

TCP6Enabled returns true if dialing and listening for IPv4 TCP is enabled.

Types

type TCPListener

type TCPListener struct {
	net.Listener
	// contains filtered or unexported fields
}

TCPListener listens for the addr passed to NewTCPListener.

It also gathers various stats for the accepted connections.

func NewTCPListener

func NewTCPListener(name, addr string, useProxyProtocol bool, tlsConfig *tls.Config) (*TCPListener, error)

NewTCPListener returns new TCP listener for the given addr and optional tlsConfig.

name is used for metrics. Each listener in the program must have a distinct name.

If useProxyProtocol is set to true, then the returned listener accepts TCP connections via proxy protocol. See https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt

func (*TCPListener) Accept

func (ln *TCPListener) Accept() (net.Conn, error)

Accept accepts connections from the addr passed to NewTCPListener.
