Support for rngd(8)

[atoponce]

More of a wishlist, but I don't see how to add it as a HRNGDEVICE for rngd(8). Possible?

+1 so we can use it to feed /dev/random so all applications can benefit from the better entropy.

I find rngd too buggy and scary for my taste. For example, by default it only uses Intel's RDRAND data and never reads from an Infnoise device, because RDRAND is so fast, it fills the entropy pool before any other TRNG has a chance to do anything.

It will only use RDRAND if you've loaded the kernel module and it is being exported as /dev/hwrng.

Which is true by default on Ubuntu 14.04, IIRC. Scarry stuff.

If RDRAND is available, the kernel is already using it to reseed the CRNG when the module is loaded. rngd(8) isn't needed.
