Description:
------------
A SOCK_DGRAM SOL_UDP socket using socket_bind to an IP address
associated with an interface will not see UDP broadcasts destined to
255.255.255.255. I do not know if this is intended but you can see
them
when listening on 0.0.0.0
Reproduce code:
---------------
<?php
//listens for dhcp requests
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
//you must bind to 0.0.0.0 to actually see anything
socket_bind($socket, "10.66.66.1", 67);
while(1)
{
if($src = @socket_recv($socket, $data, 9999, 0))
{
echo "data!\n";
}
}
?>
Expected result:
----------------
When a DHCP request is made we should see "data!" echoed.
Actual result:
--------------
Nothing was read on the interface - it can only see localhost or direct
packets sent to it (destination interface IP address).
