-Subject: Use getentropy() if arc4random_buf() is not available
-
-This allows to fix CVE-2017-2626 on Linux platforms without pulling in
-libbsd.
-The libc getentropy() is available since glibc 2.25 but also on OpenBSD.
-For Linux, we need at least a v3.17 kernel. If the recommended
-arc4random_buf() function is not available, emulate it by first trying
-to use getentropy() on a supported glibc and kernel. If the call fails,
-fall back to the current (partly vulnerable) code.
