OK, I checked all of that carefully, I can't see any configuration
problems, and what you are trying to do should work fine.
The behaviour that you are seeing can be explained perfectly if only the
first address assigned to an interface is be used. This points to the
netlink code, which is used to find the list of all the addresses on an
interface. If that fails, it silently drops back to the older API which
finds only one interface.
It's even possible that the binary you have was compiled without netlink
support, but that's unlikely unless Gentoo have done very strange things.
This code tested fine here, so it's likely there's something different
between my system and yours.
How we proceed depends on your abilities with gdb. If you are familiar
with running code under gdb, I can give you a breakpoint, and you can
single step through the relevant code and send me the results. If you
don't know gdb, we can get the same effect, but I'll need to send you a
specially instrumted version of the code to run.
Let me know.
Cheers,
Simon.
