#17066 new task

Avoid assuming relays have a single IPv4/IPv6 address

Description

Many areas of the Tor codebase assume that a relay has a single IPv4 address, or perhaps an IPv4 and an IPv6 address. Multi-homed relays may have many such addresses.

Therefore, some callers of get_interface_address[6] may be able to use the list of addresses from the get_interface_address6_list function introduced in #17027.

We should review all calls to get_interface_address and get_interface_address6 to see if they would benefit from using a list instead.

I don't think I'm going to have time for IPv6 and addresses until December.
This is a code review task, many people can help log tickets and patches.

Tentatively assigning one to you, teor, unless you find somebody else who's excited. :)

I think this can wait for 0.2.9, #17840 catches a lot of these anyway, and #6939 will catch another important instance.

I don't have time to do this in 0.2.9.

Finally admitting that 0.3.??? was a euphemism for Tor: unspecified all along.
