Hi,
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
spice-server sets "ai.ai_flags = AI_PASSIVE | AI_ADDRCONFIG", which should make getaddrinfo() pick something reasonable, specifically listen on ipv6 only if the machine actually has ipv6 connectivity. I think this is the behavior we want here.
* when ipv4 and no addr= option is set, listen on 0.0.0.0
Works today.
* when ipv6 is set, set IPV6_ONLY to 1 to make sure that spice server won't listen on ipv4
Trivially to add, see patch.
* when conflicting ipvx and addr= options are set, error out (this already works fine)
Works today indeed. cheers, Gerd
