Thanks for the explanation. Pidgin probably needs to keep the source
address matching partly for security, and also possibly to disambiguate
users. Binding to the advertised address probably wouldn't work in this
case, as the target wouldn't have a route back for the global address
prefix.

Part of the reason this behavior exists in Avahi is that many
applications do not correctly retrieve the scope ID (interface index)
when doing hostname resolution, and if not supplied then connection to
such a link local address will fail. Applications are likely to receive
such an address at
Just found bug #1102906 raised against avahi for this behaviour years
ago..

Title:
Bonjour messages not received if one party has global ipv6
Just realised that the heat had addled my brain - this will get the link
local address of target, not the originator. We could enumerate link
local addresses on the originator and add a field to the mdns text
record, but by definition those addresses are only valid on a particular
interface, and
Proof of concept of getting link local address for a specific ifindex.

Looking at the source, when browsing/resolving mdns, we get an interface
ID passed to the callback. So it should be possible call
if_indextoname() on that, then walk getifaddr() output to find the
interface and then its link-local address, and that add that to the list
of IPs ...

May be a long-standing avahi problem, but Pidgin may need to work around
it:

(For those trying to work around this, just disabling IPv6 through
sysctl doesn't necessarily help - some combination of Network Manager
and avahi seems to manage to advertise a link-local address even in this
instance. v6 support can be turned off separately in avahi-daemon.conf)
