+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.
