Description:
------------
When enabling ssl on a socket with php 7.0.24 the handshake blocks the socket. I expect the
enable_crypto to immediately return "0" if the socket is in non-blocking mode and there is
not enough data available to perform the handshake.
Test script:
---------------
<?php
$ssl_stream_ctx = stream_context_create(array(
'ssl' => array(
'local_cert' => 'cert.pem',
'verify_peer' => FALSE,
),
));
$listener = @stream_socket_server("tcp://127.0.0.1:1234",$errno,$errstr,STREAM_SERVER_BIND
| STREAM_SERVER_LISTEN, $ssl_stream_ctx);
stream_set_blocking($listener, FALSE);
$peerName = FALSE;
$sock = @stream_socket_accept($fd, 0.01, $peerName);
stream_set_blocking($sock, FALSE);
$data = stream_socket_recvfrom($sock,1,STREAM_PEEK);
if ($data[0] == "\x16") {
$sslInitStartTime = microtime(TRUE);
$ret = stream_socket_enable_crypto($sock, TRUE, STREAM_CRYPTO_METHOD_SSLv23_SERVER);
$sslInitEndTime = microtime(TRUE);
$sslInitTime = $sslInitEndTime - $sslInitStartTime;
if ($sslInitTime >= 0.1) {
echo "ERROR SSL INIT TOOK TOO LONG." . PHP_EOL;
}
}
Expected result:
----------------
Expect to return immediately and not hange > 0.1sec
Actual result:
--------------
Script hangs sometimes up to several seconds with "far away high-latency" clients.
