Package: libc6 Version: 2.7-15 Severity: normal
Hello, the getaddrinfo call with a hints set to AI_V4MAPPED should return IPv4 mapped addresses if they are available. hints.ai_family = AF_INET6; hints.ai_socktype = SOCK_STREAM; hints.ai_protocol = 0; /* Any protocol */ hints.ai_canonname = NULL; hints.ai_addr = NULL; hints.ai_next = NULL; hints.ai_flags = AI_V4MAPPED; However, this doesn't work. I only get the mapped V4 adresses when I do this: hints.ai_flags = AI_V4MAPPED | AI_ALL; However the AI_ALL flag has a different meaning. If I compare this behaviour with opensolaris, there I DO get V4 mapped addresses with only AI_V4MAPPED set in the hints. Reading the manual page, and also the docs on opengroup.org, I would expect the following behavior: Only AI_V4MAPPED -> return IPv6 addresses only if available, if not available, return IPv4 mapped AI_V4MAPPED | AI_ALL -> return IPv6 addresses and IPv4 mapped addresses. Which is not what glibc does. I'll see if I can come up with a patch somewhere in the next days.
