From 121db29a93c651b8b62e8701bb0f16c231b08257 Mon Sep 17 00:00:00 2001 From: Kevin Krakauer Date: Wed, 27 Feb 2019 14:30:20 -0800 Subject: Ping support via IPv4 raw sockets. Broadly, this change: * Enables sockets to be created via `socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)`. * Passes the network-layer (IP) header up the stack to the transport endpoint, which can pass it up to the socket layer. This allows a raw socket to return the entire IP packet to users. * Adds functions to stack.TransportProtocol, stack.Stack, stack.transportDemuxer that enable incoming packets to be delivered to raw endpoints. New raw sockets of other protocols (not ICMP) just need to register with the stack. * Enables ping.endpoint to return IP headers when created via SOCK_RAW.
