[PATCH 00/10] RFC: Preliminaries for using share IPv4 & IPv6 sockets

[David Gibson <david@gibson.dropbear.id.au>]

We want to use the same sockets to listen on both IPv4 and IPv6
addresses (at least on Linux which allows this).  This isn't too
complicated conceptually, but to make it work we need to unify
handling of v4 and v6 connections more than we currently have.

This isn't really ready to go, but I'm posting for reference.  It's
divided into rather a lot of steps, because I kept hitting problems
and not being sure exactly what change had broken things.

Based on my earlier series making handling of IPv4 addresses endian
safer.

David Gibson (10):
  tcp: no v6 flag in ref
  tcp: Helper to encode IPv4-mapped IPv6 addresses
  tcp: Partially unify IPv4 and IPv6 paths in tcp_hash_match()
  tcp: Hash IPv4 and IPv4-mapped-IPv6 addresses the same
  tcp: Take tcp_hash_insert() address from struct tcp_conn
  tcp:  Unify IPv4 and IPv6 paths for hashing and matching
  tcp: Remove ugly address union from struct tcp_conn
  tcp: Unify initial sequence numbers for IPv4 and IPv6
  tcp: Have tcp_seq_init() take its parameters from struct tcp_conn
  tcp: Fix small error in tcp_seq_init() time handling
