Types

type Endpoint

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

Endpoint is a wrapper around stack.LinkEndpoint and stack.NetworkDispatcher that can be used to implement nesting safely by providing lifecycle concurrency guards.

See the tests in this package for example usage.

func (*Endpoint) ARPHardwareType

func (e *Endpoint) ARPHardwareType() header.ARPHardwareType

ARPHardwareType implements stack.LinkEndpoint.ARPHardwareType

func (*Endpoint) AddHeader

func (e *Endpoint) AddHeader(pkt stack.PacketBufferPtr)

AddHeader implements stack.LinkEndpoint.AddHeader.

func (*Endpoint) Attach

func (e *Endpoint) Attach(dispatcher stack.NetworkDispatcher)

Attach implements stack.LinkEndpoint.

func (*Endpoint) Capabilities

func (e *Endpoint) Capabilities() stack.LinkEndpointCapabilities

Capabilities implements stack.LinkEndpoint.

func (*Endpoint) DeliverLinkPacket

func (e *Endpoint) DeliverLinkPacket(protocol tcpip.NetworkProtocolNumber, pkt stack.PacketBufferPtr)

DeliverLinkPacket implements stack.NetworkDispatcher.

func (*Endpoint) DeliverNetworkPacket

func (e *Endpoint) DeliverNetworkPacket(protocol tcpip.NetworkProtocolNumber, pkt stack.PacketBufferPtr)

func (*Endpoint) GSOMaxSize

func (e *Endpoint) GSOMaxSize() uint32

GSOMaxSize implements stack.GSOEndpoint.

func (*Endpoint) Init

func (e *Endpoint) Init(child stack.LinkEndpoint, embedder stack.NetworkDispatcher)

Init initializes a nested.Endpoint that uses embedder as the dispatcher for child on Attach.

See the tests in this package for example usage.
