Description:
------------
fsockopen() connect to a server always failed. After some tests it is confirmed due to a bug in a SSL function call which only occur in new version:
5.2.6 - passed
5.2.17 - passed
5.3.0 - passed
5.3.1 - passed
5.3.2 - failed
5.3.3 - failed
5.3.6 - failed
The bug was introduced from svn revision #291493 "merge from trunk: openssl sni support" from the function call to SSL_set_tlsext_host_name(sslsock->ssl_handle, sslsock->sni).
If I remark this function, everything works fine.
I have no further idea what is this function do, and what side effect without this function. Please advice and hope a fix would be available. Thank you.
Test script:
---------------
<?
$fp = fsockopen("ssl://smtpb.scig.gov.hk", 465, $errno, $errstr, 30);
if (!$fp) {
echo "fail: $errstr ($errno)\n";
} else {
echo "success";
}
?>
Expected result:
----------------
$fp is a non-zero handle, the screen will show "success"
Actual result:
--------------
$fp is EMPTY, the screen will show:
Warning: fsockopen() [function.fsockopen]: SSL operation failed with code 1. OpenSSL Error messages: error:14094417:SSL routines:func(148):reason(1047) in /www/test.php on line 2

1. The function call is located in ext/openssl/xp_ssl.c 2. A workaround is replace the line fsockopen() with: $context = stream_context_create(array( 'ssl' => array('SNI_server_name' => 'smtpb.scig.gov.hk'), )); $fp = stream_socket_client("tcp://smtpb.scig.gov.hk:465", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context);What you're calling workaround is actually the solution. Obviously, that server (which appears to be no longer available) required SNI[1]. To enable that as of PHP 7.0.0: $context = stream_context_create([ 'ssl' => [ 'SNI_enabled' => true, 'peer_name' => 'smtpb.scig.gov.hk' ], ]); [1] <https://en.wikipedia.org/wiki/Server_Name_Indication>
