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 protcol (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.
