What are you trying to do?

I would like to have a "bind-to-subnet" semantic with IPv6.

This is currently working with IPv4, and the setup is the follow:

- setup a dummy network device configured with any-IP
- add an any-IP route
- bind() on the dummy device

in this way we can effectively bind a process to a particular subnet
(by binding it to a dummy device which is receiving all the packets
from a particular subnet).

The point of using dummy devices is that we can configure multiple ones
(and so we can bind multiple processes to multiple subnets).

Does what you're trying to do work on an older kernel?  Which kernel
version does it break at?

btw. afaik any-ip doesn't work with IPv4 on any un-patched kernel (the
IPv4 support patch was reverted).

This is actually working with IPv4 (as I said I'm using a recent kernel,
4.1), and the fact that you say it's not supposed to work leads me to
think that maybe we are not talking about the same feature.
