Re: PHP/SELinux: libselinux wrappers

[KaiGai Kohei <kaigai@ak.jp.nec.com>]

Hi,

http://koji.fedoraproject.org/koji/packageinfo?packageID=7917

Now the "php-pecl-selinux" package got approved in Fedora Project.
Some days later, it will be delivered to mirrors.

BTW, I still mark its state as "devel". It means we have a possibility
to change APIs. If you found anything to be improved, please tell me.


The following example is just a toy, which implements
Paul's "getpeercon_server.c" example in PHP.
--------------
#!/usr/bin/php -q
<?
if (count($argv) < 2) {
     echo "usage: ".$argv[0]." <port>\n";
     return 1;
}

$conn_url = sprintf("tcp://0.0.0.0:%u", $argv[1]);
$server = stream_socket_server($conn_url, $errno, $errmsg);
if (!$server) {
     echo "error: $errmsg ($errno)\n";
     return 1;
}

while (($client = stream_socket_accept($server))) {
     $ipaddr = stream_socket_get_name($client, true);
     $peercon = selinux_getpeercon($client);
     printf("connect %s => %s\n", $ipaddr, !$peercon ? "null" : $peercon);
     fclose($client);
}
fclose($server);
?>
--------------

   [kaigai@saba ~]$ ./peersock.php 1234
   connect 10.19.71.82:4643 => user_u:user_r:user_t:s0
   connect 127.0.0.1:36277 => staff_u:staff_r:staff_t:s0
   connect 10.19.71.81:48902 => null

I guess it also can be used for education purpose because it enables
to observe the behavior of SELinux with quick try-and-error steps. :-)

Thanks,
