type Stack

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

Stack is a gVisor network stack connected to a VPN packet device.

func New

func New(addresses []netip.Prefix, mtu uint32, device packetDevice) (*Stack, error)

func (*Stack) AddAddress

func (s *Stack) AddAddress(prefix netip.Prefix) error

AddAddress adds an address that can receive packets in the userspace stack. It does not change host networking.

func (*Stack) Addresses

func (s *Stack) Addresses() []netip.Prefix

func (*Stack) Close

func (s *Stack) Close() error

func (*Stack) DialContext

func (s *Stack) DialContext(ctx context.Context, network, address string) (net.Conn, error)

func (*Stack) DialICMPContext

func (s *Stack) DialICMPContext(ctx context.Context, network, address string) (*ICMPConn, error)

func (*Stack) Done

func (s *Stack) Done() <-chan struct{}

func (*Stack) Listen

func (s *Stack) Listen(network, address string) (net.Listener, error)

func (*Stack) ListenICMP

func (s *Stack) ListenICMP(network, address string) (*ICMPConn, error)

func (*Stack) ListenPacket

func (s *Stack) ListenPacket(network, address string) (net.PacketConn, error)

func (*Stack) RemoveAddress

func (s *Stack) RemoveAddress(prefix netip.Prefix) error

RemoveAddress removes an address previously added to the userspace stack. It does not change host networking.
