Functions

func DialMarkedWithContext

func DialMarkedWithContext(ctx context.Context, network string, addr string, platformData *PlatformData, mark int) (net.Conn, error)

DialMarkedWithContext will dial a TCP connection to the provide address and mark the socket with the provided mark.

func GetInterfaces

func GetInterfaces() map[string]struct{}

GetInterfaces retrieves all the local interfaces.

func NewSocketListener

func NewSocketListener(ctx context.Context, port string, mark int) (net.Listener, error)

NewSocketListener will create a listener and mark the socket with the provided mark.

Types

type Control

type Control func(network, address string, c syscall.RawConn) error

Control represents the dial control used to manipulate the raw connection.

func ControlFunc

func ControlFunc(mark int, block bool, platformData *PlatformData) Control

ControlFunc used in the dialer.

type PlatformData

type PlatformData struct {
	// contains filtered or unexported fields
}

PlatformData is proxy/socket data (platform-specific)

func RemovePlatformData

func RemovePlatformData(l net.Listener, conn net.Conn) *PlatformData

RemovePlatformData removes the data from storage and returns it

func TakePlatformData

func TakePlatformData(l net.Listener, ip net.IP, port int) *PlatformData

TakePlatformData removes the data from storage and returns it

type PlatformDataControl

type PlatformDataControl struct {
}

PlatformDataControl dummy impl PlatformDataControl is only needed for Windows now, and allows retrieval of kernel socket data.

func NewPlatformDataControl

func NewPlatformDataControl() *PlatformDataControl

NewPlatformDataControl returns initialized PlatformDataControl

func (*PlatformDataControl) StorePlatformData

func (n *PlatformDataControl) StorePlatformData(ip net.IP, port int, platformData *PlatformData)

StorePlatformData saves the data after GetDestInfo is called.

type ProxiedConnection

type ProxiedConnection struct {
	// contains filtered or unexported fields
}

ProxiedConnection is a proxied connection where we can recover the original destination.

func (*ProxiedConnection) Close

func (p *ProxiedConnection) Close() error

Close closes the connection.

func (*ProxiedConnection) GetOriginalDestination

func (p *ProxiedConnection) GetOriginalDestination() (net.IP, int)

GetOriginalDestination sets the original destination of the connection.

func (*ProxiedConnection) GetPlatformData

func (p *ProxiedConnection) GetPlatformData() *PlatformData

GetPlatformData gets the platform-specific socket data (needed for Windows)

func (*ProxiedConnection) GetTCPConnection

func (p *ProxiedConnection) GetTCPConnection() *net.TCPConn

GetTCPConnection returns the TCP connection object.

func (*ProxiedConnection) LocalAddr

func (p *ProxiedConnection) LocalAddr() net.Addr

LocalAddr implements the corresponding method of net.Conn, but returns the original address.

func (*ProxiedConnection) Read

func (p *ProxiedConnection) Read(b []byte) (n int, err error)

Read reads data from the connection.

func (*ProxiedConnection) RemoteAddr

func (p *ProxiedConnection) RemoteAddr() net.Addr

RemoteAddr returns the remote address

func (*ProxiedConnection) SetDeadline

func (p *ProxiedConnection) SetDeadline(t time.Time) error

SetDeadline passes the read deadline to the original TCP connection.

func (*ProxiedConnection) SetReadDeadline

func (p *ProxiedConnection) SetReadDeadline(t time.Time) error

SetReadDeadline implements the call by passing it to the original connection.

func (*ProxiedConnection) SetWriteDeadline

func (p *ProxiedConnection) SetWriteDeadline(t time.Time) error

SetWriteDeadline implements the call by passing it to the original connection.

func (*ProxiedConnection) Write

func (p *ProxiedConnection) Write(b []byte) (n int, err error)

Write writes data to the connection.

type ProxiedListener

type ProxiedListener struct {
	// contains filtered or unexported fields
}

ProxiedListener is a proxied listener that uses proxied connections.

func (ProxiedListener) Accept

func (l ProxiedListener) Accept() (c net.Conn, err error)

Accept implements the accept method of the interface.

func (ProxiedListener) Addr

func (l ProxiedListener) Addr() net.Addr

Addr implements the Addr method of net.Listener.

func (ProxiedListener) Close

func (l ProxiedListener) Close() error

Close implements the Close method of the net.Listener.
