Bug#738652: libc6: libnss_files behavior changed beetween 2.13-38 and 2.13-38+deb7u1

[Mehdi Abaakouk <sileht@sileht.net>]

Package: libc6
Version: 2.17-97
Severity: normal
Tags: ipv6

Dear Maintainer,

I have recently upgraded some wheezy servers and one of the
upgraded packages cause to me some troubles.

After upgrading libc6 packages from 2.13-38 to 2.13-38+deb7u1, resolving ipv6 hosts won't works anymore in some case.

To reproduce the issue:

make you dns resolve a host (myhost.mydomain) to a ipv4 and a ipv6

Put only the ipv4 of this hosts in the /etc/hosts files

then try to resolv the ipv6 address with ping6 that doesn't works


Downgrading to 2.13-38 solve the issue.

FYI: my nsswitch.conf is the default one (ie: hosts: files dns)


Best Regards,
