Package: samba
Version: 2:3.4.7~dfsg-1
Severity: serious
Justification: IPv4 is kinda required
Hi,
Samba binds only to IPv6 and not to IPv4. I think this breaks stuff.
Greetings,
Olaf

Version: 2:3.6.0~pre1-1
In 3.6.0pre1 util_sock.c:
#ifdef HAVE_IPV6
/*
* As IPV6_V6ONLY is the default on some systems,
* we better try to be consistent and always use it.
*
* This also avoids using IPv4 via AF_INET6 sockets
* and makes sure %I never resolves to a '::ffff:192.168.0.1'
* string.
*/
if (sock.ss_family == AF_INET6) {
int val = 1;
int ret;
ret = setsockopt(res, IPPROTO_IPV6, IPV6_V6ONLY,
(const void *)&val, sizeof(val));

s3:lib/util_sock: listen on IPv6 addresses with IPV6_ONLY (bug #7383)
This avoids getting IPv4 addresses as mapped IPv6 addresses
(e.g. ::ffff:192.168.0.1).
Before the bahavior was inconsistent between operating system
and distributions. Some system have IPV6_ONLY as default.
Now we consistently get AF_INET for IPv4 addresses and AF_INET6
for IPv6 addresses.
It also makes it possible to listen only on IPv6 now
as "::" doesn't imply "0.0.0.0" anymore. Which also
avoids confusing log messages that we were not able to
bind to "0.0.0.0".

So, this is fixed in 3.6.* releases (currently in experimental).
