[Pkg-utopia-maintainers] Bug#587961: avahi-daemon: patch for #517160 affects more than just reflector

[Julien BLACHE]

Package: avahi-daemon
Version: 0.6.25-4
Severity: normal

Hi,

The patch for #517160, filtering out link-local addresses, affects more than
just the reflector feature of avahi-daemon.

With the patch applied, it is impossible to get a link-local IPv6 address
when resolving a service, which is an issue when the LL address is the only
address advertised by the device.

This is the case with Apple's devices (#517160 takes the AirPort Extreme as an
example, the same is true for the AirPort Express) that only advertise their
LL IPv6 address via mDNS, even if they have a global address configured.

So in effect, it is no longer possible to rely on Avahi to reach any device
with a similar behaviour over IPv6.

The LL filtering should be done only for the reflector.

JB.
