Subject: getaddrinfo(3) / AI_ADDRCONFIG
Date: Mon, 9 Jul 2018 11:16:04 -0400 [thread overview]
Message-ID: <CAF4BF-S7VOBq9YnaN3gu7N==aujkfytgPN6qiXXKyHjO=gn-xw@mail.gmail.com> (raw)
Hi list,
I have a patch for getaddrinfo(3) so that AI_ADDRCONFIG is properly
supported. Currently, if user code passes in the aforementioned flag,
there is no check to see whether a non-loopback network interface is
configured with the specified (or unspecified) address family before
returning results, which is what getaddrinfo(3) should do according to
[1].
As a result of the current behaviour, musl's getaddrinfo(3) would
return e.g. "::1" to user code even when no interfaces (including lo)
were configured with IPv6 addresses. I've documented this to some
extent here [2].
Please see the patch at [3] for my fix. Any feedback is welcome. The
patch It applies against master and 1.1.19, but possibly other
releases.
