[pgpool-hackers: 4602] heartbeat and SO_BINDTODEVICE

[Tatsuo Ishii]

wd_create_hb_recv_socket() and wd_create_hb_send_socket() calls
setsockopt(2) like this:

	struct ifreq i;
	strlcpy(i.ifr_name, hb_if->if_name, sizeof(i.ifr_name));
	if (setsockopt(sock, SOL_SOCKET, SO_BINDTODEVICE, &i, sizeof(i)) == -1)
	:

I think this is not quite correct since the 4th arugument should be
just a null terminated string (device name), not struct ifreq. From
socket(7) man page:

       SO_BINDTODEVICE
              Bind this socket to a particular device like “eth0”,
              as specified in the passed interface name.  If the name
              is an empty string or the option length is zero, the
              socket device binding is removed.  The passed option is
              a variable- length null-terminated interface name string
              with the maximum size of IFNAMSIZ.

Patch attached.
