Overview ¶
Package raw provides the implementation of raw sockets (see raw(7)). Raw sockets allow applications to:
- manually write and inspect transport layer headers and payloads
- receive all traffic of a given transport protocol (e.g. ICMP or UDP)
- optionally write and inspect network layer and link layer headers for packets
Raw sockets don't have any notion of ports, and incoming packets are demultiplexed solely by protocol number. Thus, a raw UDP endpoint will receive every UDP packet received by netstack. bind(2) and connect(2) can be used to filter incoming packets by source and destination.

Functions ¶
func NewEndpoint ¶
func NewEndpoint(stack *stack.Stack, netProto tcpip.NetworkProtocolNumber, transProto tcpip.TransportProtocolNumber, waiterQueue *waiter.Queue) (tcpip.Endpoint, *tcpip.Error)
NewEndpoint returns a raw endpoint for the given protocols. TODO(b/129292371): IP_HDRINCL and AF_PACKET.
Types ¶
type EndpointFactory ¶
type EndpointFactory struct{}
EndpointFactory implements stack.UnassociatedEndpointFactory.
func (EndpointFactory) NewUnassociatedRawEndpoint ¶
func (EndpointFactory) NewUnassociatedRawEndpoint(stack *stack.Stack, netProto tcpip.NetworkProtocolNumber, transProto tcpip.TransportProtocolNumber, waiterQueue *waiter.Queue) (tcpip.Endpoint, *tcpip.Error)
NewUnassociatedRawEndpoint implements stack.UnassociatedEndpointFactory.
