Log message:
Do propper kernel input validation for in_control() ioctl(2)
SIOCGIFADDR, SIOCGIFNETMASK, SIOCGIFDSTADDR, SIOCGIFBRDADDR,
SIOCSIFADDR, SIOCSIFNETMASK, SIOCSIFDSTADDR, and SIOCSIFBRDADDR.
Name in_ioctl_set_ifaddr() consistently. Use in_sa2sin() to validate
inet address. Combine if_addrlist loops and add comment. Although
netmask is not a inet address, length must be valid.
