For example, this IPV6_V6ONLY socket option is flawed.  What we

There is nothing ipv6 specific about such a socket attribute.

So please, create instead "SO_ONEFAMILY" or similar generic
socket option.

I still need to review the rest of the patch for functional
correctness.  This is probably the most complex area of the
socket identity code in TCP/UDP :-)

While you are grotting aroung in this area - a thought / request.

When we get IPv4 link-local autoconf addressing in widespread use, there is a 
problem on multi-homed machines.

Assume B has two network interfaces (B1 and B2) on seperate IPv4 links (net1 
and net2). Host A is on net1 and Host C is on net2. Assume that both Host A 
and Host C have the same autoconf address. So IP address is not enough 
information for Host B to use to determine which interface to use in order to 
contact Host A (instead of Host C).

If host B has socket binding on IP+port+local interface, it all works out.

Is this going to work?
