Description Pavel Šimerda 2012-07-27 15:13:10 UTC

GLIBC's name service switch doesn't provide a way to override getaddressinfo()
which is the only function that supports IPv6 link-local addresses.

IPv6 link-local addresses don't work without the interface name (when
written as text) that then translates to scope id.

Fedora bug:

This is actually needed for link-local name resolution (whatever NSS plugin is used for it then).

Comment 2 Pavel Šimerda 2012-07-31 13:31:37 UTC

There's another usecase for getaddrinfo() in nsswitch and that is avoiding problems caused by solutions to bug 12377 including bug 12398. See discussions
in these two bug reports.
