More or less a resend of v2. On Wed, Mar 26, 2014 at 06:03:37PM -0700, H. Peter Anvin wrote: > I'm wondering more about the default. We default to 50% for > arch_get_random_seed, and this is supposed to be the default for in effect > unverified hwrngs...
Done. 50% is now the default, that's the only change from v2. Andy: the printk you pointed out already limits itself to 1/10s, which is half the default rate limit. Also, as Peter already wrote, we're dealing with true HWRNGs here; if such a device does not produce a single byte within 10 seconds something _is_ severely broken and, like a dying disk, worth to be logged. Here's one of the better circuits I found: http://www.maximintegrated.com/app-notes/index.mvp/id/3469 or offline: http://pdfserv.maximintegrated.com/en/an/AN3469.pdf Disclaimer: I'm not endorsing Maxim, it's just that paper that hits the spot IMHO. Anything wrong with feeding those bits into the input pool? Any other comments on the code?
