Hi, I learned few things about ipv6 lately. Most importantly about dual-socket that means that a process that opens ::0 automatically listens on both ipv4 _and_ ipv6 unless it sets IPV6_ONLY option of setsockopt() to 0. This is pretty important wrt dual-stack configurations because they can be implemented with just slight changes to spice server (unlike the old RFE requesting listening on multiple addresses): * when no addr= or ipvx options are set, listen on ::0 * when ipv4 and no addr= option is set, listen on 0.0.0.0 * when ipv6 is set, set IPV6_ONLY to 1 to make sure that spice server won't listen on ipv4 * when conflicting ipvx and addr= options are set, error out (this already works fine) This will affect upper layers though, given bugs like https://bugzilla.redhat.com/show_bug.cgi?id=832121 , but it seems to me like the step in the right direction. Any thoughts/comments before I file this as a bug?
