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(local, remote tcpip.LinkAddress, protocol tcpip.NetworkProtocolNumber, pkt *stack.PacketBuffer)

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) DeliverNetworkPacket

func (e *Endpoint) DeliverNetworkPacket(remote, local tcpip.LinkAddress, protocol tcpip.NetworkProtocolNumber, pkt *stack.PacketBuffer)

DeliverNetworkPacket implements stack.NetworkDispatcher.

func (*Endpoint) DeliverOutboundPacket

func (e *Endpoint) DeliverOutboundPacket(remote, local tcpip.LinkAddress, protocol tcpip.NetworkProtocolNumber, pkt *stack.PacketBuffer)

DeliverOutboundPacket implements stack.NetworkDispatcher.DeliverOutboundPacket.

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.

func (*Endpoint) IsAttached

func (e *Endpoint) IsAttached() bool

IsAttached implements stack.LinkEndpoint.

func (*Endpoint) LinkAddress

func (e *Endpoint) LinkAddress() tcpip.LinkAddress

LinkAddress implements stack.LinkEndpoint.

func (*Endpoint) MTU

func (e *Endpoint) MTU() uint32

MTU implements stack.LinkEndpoint.

func (*Endpoint) MaxHeaderLength

func (e *Endpoint) MaxHeaderLength() uint16

MaxHeaderLength implements stack.LinkEndpoint.

func (*Endpoint) SupportedGSO

func (e *Endpoint) SupportedGSO() stack.SupportedGSO

SupportedGSO implements stack.GSOEndpoint.

func (*Endpoint) Wait

func (e *Endpoint) Wait()

Wait implements stack.LinkEndpoint.

func (*Endpoint) WritePacket

func (e *Endpoint) WritePacket(r stack.RouteInfo, protocol tcpip.NetworkProtocolNumber, pkt *stack.PacketBuffer) tcpip.Error

WritePacket implements stack.LinkEndpoint.

func (*Endpoint) WritePackets

func (e *Endpoint) WritePackets(r stack.RouteInfo, pkts stack.PacketBufferList, protocol tcpip.NetworkProtocolNumber) (int, tcpip.Error)

WritePackets implements stack.LinkEndpoint.
