Functions ¶
func ICMPv4Echo ¶
ICMPv4Echo returns an ICMPv4 echo packet.
func ICMPv6Echo ¶
ICMPv6Echo returns an ICMPv6 echo packet.
func RxICMPv4EchoReply ¶
RxICMPv4EchoReply constructs and injects an ICMPv4 echo reply packet on the provided endpoint.
func RxICMPv4EchoRequest ¶
RxICMPv4EchoRequest constructs and injects an ICMPv4 echo request packet on the provided endpoint.
func RxICMPv6EchoReply ¶
RxICMPv6EchoReply constructs and injects an ICMPv6 echo reply packet on the provided endpoint.
func RxICMPv6EchoRequest ¶
RxICMPv6EchoRequest constructs and injects an ICMPv6 echo request packet on the provided endpoint.
func SetupRoutedStacks ¶
SetupRoutedStacks creates the NICs, sets forwarding, adds addresses and sets the route tables for the passed stacks.
func SetupRouterStack ¶
SetupRouterStack creates the NICs, sets forwarding, adds addresses and sets the route table for a stack that should operate as a router.
Types ¶
type EndpointWithDestinationCheck ¶
EndpointWithDestinationCheck is a link endpoint that checks the destination link address before delivering network packets to the network dispatcher.
func NewEthernetEndpoint ¶
func NewEthernetEndpoint(ep stack.LinkEndpoint) *EndpointWithDestinationCheck
NewEthernetEndpoint returns an ethernet link endpoint that wraps an inner link endpoint and checks the destination link address before delivering network packets to the network dispatcher.
See ethernet.Endpoint for more details.
func (*EndpointWithDestinationCheck) DeliverNetworkPacket ¶
func (e *EndpointWithDestinationCheck) DeliverNetworkPacket(proto tcpip.NetworkProtocolNumber, pkt stack.PacketBufferPtr)
DeliverNetworkPacket implements stack.NetworkDispatcher.
