Bug #64330 stream_socket_server() creates wrong Abstract Namespace UNIX sockets
Submitted: 2013-03-01 08:20 UTC Modified: -
From: a dot yamanoi at gmail dot com Assigned:
Status: Closed Package: Streams related
PHP Version: 5.4.12 OS: Linux
Private report: No CVE-ID:
 [2013-03-01 08:20 UTC] a dot yamanoi at gmail dot com
Description:
------------
stream_socket_server("unix://\x00/foo/bar") doesn't bind
a UNIX domain socket to the abstract namespace correctly.

The actual namespace string seems to be padded right with "\x00"s.

e.g.
"\x00/foo/bar\x00\x00...\x00"

So the stream_socket_client("unix://\x00/foo/bar") test below fails.
According to Bug #44127, stream_socket_client() works fine now.

The problem occurs in PHP 5.4.12 and the latest 5.4 snap(Built on: Mar 01, 2013 
02:30 UTC).

Test script:
---------------
<?php
$server = stream_socket_server("unix://\x00/MyBindName");
$client = stream_socket_client("unix://\x00/MyBindName");
if ($client) {
    echo "ok\n";
}
?>

Expected result:
----------------
ok


Actual result:
--------------
PHP Warning: stream_socket_client(): unable to connect to unix://\0/MyBindName 
(Connection refused) in ...
