php_network.h integer overflow

[chongwick]

Description

The following code:

<?php
array( 'timeout' => PHP_INT_MAX, 'max_redirects' => PHP_INT_MAX, 'user_agent' => 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3', ), ));
$fp = fopen('http://example.com', 'r', false, $stream);

Resulted in this output:

/home/dan/php-8.3.9/main/php_network.h:166:29: runtime error: signed integer overflow: -9223372036854775808 * 1000 cannot be represented in type 'long int'

php-src/main/php_network.h

Lines 163 to 168 in 67ba890

	static inline int php_tvtoto(struct timeval *timeouttv)
	{
	if (timeouttv) {
	return (timeouttv->tv_sec * 1000) + (timeouttv->tv_usec / 1000);
	}
	return -1;

looks indeed fishy.
