2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* if_ioctl.c: (interface_list_ioctl) Use if_get_by_name_len.
* if_proc.c: (ifaddr_proc_ipv6) Increase size of ifname buffer to
avoid overflow.
* kernel_socket.c: (ifan_read) Use if_get_by_name_len.
* if.h: Fix comments to reflect that if_lookup_by_name and
if_get_by_name now require the argument strings to be NUL-terminated.
* if.c: (if_lookup_by_name) Compare using strcmp.
(if_get_by_name) Pass strlen(ifname) as 2nd arg to if_create.
