>Description:
 With new sysctl infrastracture, hostnamelen stored in the kernel is
no longer properly set. Some kernel functions still refers this. In my
case, ni6_nametodns is called with zero hostnamelen, so this node
sends ICMP6_WRUREPLY with hostname "".
>How-To-Repeat:
ping6 -w ff02::1%lo0
>Fix:
#define hostnamelen      strlen(hostname)
