I traced back that problem to a call in libapr1, in call_resolver()
getaddrinfo(127.0.0.1, NULL, hints, ...) that returns -9
because hints contains AI_ADDRCONFIG
Without that hint, it works.
Extract from call_resolver:
if (family == APR_UNSPEC) {
/* By default, only look up addresses using address types for
* which a local interface is configured, i.e. no IPv6 if no
* IPv6 interfaces configured. */
hints.ai_flags = AI_ADDRCONFIG;
}
Documentation from getaddrinfo(3):
If hints.ai_flags includes the AI_ADDRCONFIG flag, then IPv4 addresses
are returned in the list pointed to by res only if the local system has
at least one IPv4 address configured, and IPv6 addresses are only
returned if the local system has at least one IPv6 address configured.
But obviously, having an IPv6 on eth0, and both an IPv4 and IPv6 in lo, is not
enough to enable IPv4 resolution.
The manpage doesn't match the RFC3493 which explicitly exclude the loopback
addresses:
If the AI_ADDRCONFIG flag is specified, IPv4 addresses shall be
returned only if an IPv4 address is configured on the local system,
and IPv6 addresses shall be returned only if an IPv6 address is
configured on the local system. The loopback address is not
considered for this case as valid as a configured address.
This makes sense, given that a system almost always have both IPv4 and
IPv6 loopback addresses. If loopback adresses were taken into account,
it would make the AI_ADDRCONFIG flag useless.
For me the problem is in call_resolver, which actually should not use
the AI_ADDRCONFIG flag. To know to which addresses to bind to, it should
use the AI_PASSIVE flag instead.
I am therefore cloning this bug to manpages-dev so that the
documentation can be updated, and reassigning the original bug to
libapr1 as the bug has to be fixed there.

Bug#660526: stdio.h is incomplete for POSIX 2008
Package: libc6-dev Version: 2.11.3-3 I apology if this bug has already been reported but I am unable to find it through the web bug report interface. POSIX 2008 requires that stdio.h expose ssize_t, va_list, and getline (among others) if _POSIX_C_SOURCE is 200809L or greater. However, the 2.11 glibc does not conform to this (see http://sourceware.org/bugzilla/show_bug.cgi?id=11125). I'm currently working on some GNU coreutils and since I'm working with the Debian squeeze I got this issue. See thread http://lists.gnu.org/archive/html/coreutils/2012-02/msg00128.html As I said in the above thread, this issue has been fixed in GNU libc cd2f000c074b07931bd78ab5ff5fa3c0f7db628a commit. I wonder if you could backport this bug fix ? BTW, I take this mail to really thank you for this great distribution.
