I don't think this is a bug.
Assuming that the server accepting socket is AF_INET6, you should do
the following on the socket:
int on;
on = 1;
setsockopt(fd, IPPROTO_IPV6, IPV6_BINDV6ONLY,
&on, sizeof(on));
Otherwise, the inpcb is marked with INP_IPV4 which means the IPv4 packet
can be received by the socket. The address is then mapped to IPv6 because
the socket is AF_INET6.
