Description:
------------
While PHP is running in FPM with chroot safe_mode, and the session.save_handler is "files".

#ext/session/mod_files.c: PS_CREATE_SID_FUNC(files)
{{
    sid = php_session_create_id((void**)&data);
}}
This statement would always return NULL to sid, because of php_random_bytes() returning FAILURE.


SOLUTION:

ext/standard/random.c: 

Line 94: #elif HAVE_DECL_ARC4RANDOM_BUF && ((defined(__FreeBSD__) || (defined(__OpenBSD__) && OpenBSD >= 201405) || (defined(__NetBSD__) && __NetBSD_Version__ >= 700000001))




Test script:
---------------
session_start();

The effect to session_start() isn't the root cause, though;
re-classifying.

Anyhow, is the failing php_random_bytes() still an issue?  If so,
please provide a pull request[1] for better visibility.
