+preferred @file{/dev/urandom} and @code{getrandom()} interfaces too.
+
+The CPU Jitter RNG itself is part of the kernel and claims to provide good
+entropy by collecting and magnifying differences in CPU execution time as
+measured by the high-resolution timer built into modern CPUs.  It requires no
+additional hardware or external entropy source.
+
+The random bit stream generated by @command{jitterentropy-rngd} is not processed
+by a cryptographically secure whitening function.  Nonetheless, its authors
+believe it to be a suitable source of cryptographically secure key material or
+other cryptographically sensitive data.
+
+If you agree with them, start this daemon as early as possible to provide
+properly seeded random numbers to services like SSH or those using TLS during
+early boot when entropy may be low, especially in virtualised environments.")

+Subject: libgst: Add alternative multiplication overflow check
+
+Apple clang on OSX and the version on FreeBSD optimize the
+multiplication check away. Clang introduced a family of
+builtins to do the multiplication and check for the overflow
+and GCC made the API usable. For clang we would need to know
+if intptr_t is of type int, long int, long long int and
+then use the smul, smull smulll.
+Luckily clang is adopting the better interface and this is
+what we are starting to use now. This means the new code
+will be used on GCC5 (and later) and some future versions of
+clang.
+
+2015-11-07  Holger Hans Peter Freyther  <holger@freyther.de>
+
+	* build-aux/overflow-builtins.m4: Add new macro.
+	* configure.ac: Use GST_C_OVERFLOW_BUILTINS macro.
+
+2015-11-07  Holger Hans Peter Freyther  <holger@freyther.de>
+
+	* interp.inl: Add alternative mul_with_check implementation.
