commit 587d3863176dc8d82623624bbd777d1a0a4d20af
Author: Mats Erik Andersson <address@hidden>
Date:   Wed Aug 15 09:39:28 2012 +0200

    shishid: Use single stacked AF_INET6 sockets.
    
    On dual stacked hosts, running an AF_INET6 wildcard
    socket blocks AF_INET wildcards. Make it single
    stacked using IPV6_V6ONLY instead.
