Hello,

One solution would be to finish the IPv6 ioctl interface to list
addresses. The ioctl interface would need less memory allocations and is
a synchronous interface which would make it much more easier for glibc
to deal with. No timeouts and retries like with netlink are necessary.

David, would such code still be accepted?

Thanks,
Hannes
