Subject: virNetSocketCheckProtocols: handle EAI_NONAME as IPv6 unavailable
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=fbb27088eec1b54fcd5a0950b11c31d27a2598d4;p=libvirt.git

virNetSocketCheckProtocols: handle EAI_NONAME as IPv6 unavailable

When running the test suite using "unshare -n" we might have IPv6 but no
configured addresses. Due to AI_ADDRCONFIG getaddrinfo then fails with
EAI_NONAME which we should then treat as IPv6 unavailable.
