Bug description: connect timeout on successful connect
Description:
------------
On unusually slow ssl connects, we get a timeout message even through the
connect succeeded.
The offending code appears to be around line 816 of xp_ssl.c version 1.37
(the bug appears to have been around since 1.28)
struct timeval tvs, tve;
struct timezone tz;
gettimeofday(&tvs, &tz);
n = SSL_connect(sslsock->ssl_handle);
gettimeofday(&tve, &tz);
timeout -= (tve.tv_sec + tve.tv_usec /
1000000) - (tvs.tv_sec + tvs.tv_usec / 1000000);
if (timeout < 0) {
php_error_docref(NULL TSRMLS_CC,
E_WARNING, "SSL: connection timeout");
return -1;
}
The timeout is checked before the success value. A fix would be to only
check the timeout when deciding to loop again.
Reproduce code:
---------------
Peg the cpu of the test machine, attempt to make several ssl connections
out.
