Subject: net: fix tests for systems without IPv6 entries in /etc/hosts.
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=5b189c748dbc4b09e8180ce6fc6c2d0411968c48

net: fix tests for systems without IPv6 entries in /etc/hosts.

We fake up a dual IPv4/IPv6 response to localhost for testing, but it
assumed localhost6 or ip6-localhost entries.  Fall back to "::1" which
should always work.
