[avahi] [PATCH] [RFC] Untested bind to ipaddress (interface)

[Stefan de Konink]

Hello,


A small three hours ago I spoke with trs80 on IRC. Asking him about the 
possibility to bind avahi to a specific interface. This functionality I 
had just added to libvirt, and because of security reasons I would like 
to have this in every package I run on my cluster.

The option to disable multicast sounds attractive, but is not reliable 
for me. I started hacking and I come up with an *untested* patch, it 
compiles but I have my question marks with its working.


My guess is the code in main.c, wide-area.c, core.h, server.c will work.
(Minor questionmark about "::", but I guess that would be valid.)


The real work in socket.c need to be checked, especially if I can get 
away with:
ipv4_address_to_sockaddr(&local, bind_ipv4, 0);
ipv6_address_to_sockaddr(&local, bind_ipv6, 0);


I'll check the working tomorrow myself, but it is now a bit late for 
more hacking. Attached is the patch, I removed core.h from socket.c 
because I presume this was eventually a non essential include.


Anyone how wants to improve it or test it, be my guest.
