Prefer default route when checking local interface addresses
First, let us assume that all network interfaces for IP host that runs Tor instance are internal as judged by tor_addr_is_internal()
function.
There is the following code in get_interface_address6()
function.
/* Try to do this the smart way if possible. */
if ((addrs = get_interface_addresses_raw(severity))) {
int rv = -1;
SMARTLIST_FOREACH_BEGIN(addrs, tor_addr_t *, a) {
if (family != AF_UNSPEC && family != tor_addr_family(a))
continue;
if (tor_addr_is_loopback(a) ||
tor_addr_is_multicast(a))
continue;
tor_addr_copy(addr, a);
rv = 0;
/* If we found a non-internal address, declare success. Otherwise,
* keep looking. */
if (!tor_addr_is_internal(a, 0))
break;
} SMARTLIST_FOREACH_END(a);
SMARTLIST_FOREACH(addrs, tor_addr_t *, a, tor_free(a));
smartlist_free(addrs);
return rv;
}
Caller will get the last entry from a interface address smartlist. Is this okay?
