Description:
------------
The documentation says about stream_socket_enable_crypto :
Returns TRUE on success, FALSE if negotiation has failed or 0 if there
isn't enough data and you should try again (only for non-blocking
sockets).
In practice, if you feed a non blocking server socket to it, it will
block and consume lots of CPU until the SSL/TLS handshake is done or the
client connection is dropped.
Reproduce code:
---------------
<?php
$s = stream_socket_server("tcp://127.0.0.1:8888");
$c = stream_socket_accept($s);
stream_set_blocking($c, false);
$ret = stream_socket_enable_crypto($c, true,
STREAM_CRYPTO_METHOD_TLS_SERVER);
var_dump($ret);
?>
then just "telnet localhost 8888" from another term
Expected result:
----------------
script should print "int(0)" and exit
Actual result:
--------------
script blocks at the stream_socket_enable_crypto() call and is stuck in
a CPU consuming loop until the client connection is either handshaked or
dropped.
