Description:
------------
stream_socket_enable_crypto() hangs for unnegotiable SSL connections for
sockets connected in asynchronous mode.
Whilst I'm not greatly familiar with the PHP source, I believe it is caused by
the following line of code in xp_ssl.c:
timeout -= (tve.tv_sec + (float) tve.tv_usec / 1000000) - (tvs.tv_sec + (float)
tvs.tv_usec / 1000000);
I'm often seeing no difference in tve.tv_sec and tvs.tv_sec, and the difference
between tve.tv_usec and tvs.tv_usec is typically 4/5 microseconds for the
particular scenario I've been debugging. 4/1000000 deduction from the timeout
float results in essentially no change. Therefore the code loops for a very
long time. In anycase, a printf on the timeout float see's no change after
running for a good length of time.
Note: I don't believe this is the same issue as #45808, since this affects
client connections, not server connections [+ the area of code I believe to be
guilty is specific to client connections]
I'd also note that stream_set_blocking appears to have no effect on this area
of code - but I'm not sure if thats a bug or not.
Reproduce code:
---------------
<?PHP
// The given address should not be connectable..
$socket = stream_socket_client("tcp://{$address}", $errno, $errstr, 15,
STREAM_CLIENT_CONNECT|STREAM_CLIENT_ASYNC_CONNECT);
var_dump(stream_socket_enable_crypto($socket, true,
STREAM_CRYPTO_METHOD_SSLv23_CLIENT));
?>
Expected result:
----------------
0/false [after "timeout" seconds]
Actual result:
--------------
Hangs pretty much forever.
