Finally I got a question, why crypto devices that can feed the kernel entropy pool automatically have to use rngd ? I know something should check for the quality of that entropy, I wonder why the kernel itself doesnt do that tests.
For example, machines that have a wireless card, using the b43 driver, may have the ability to use the hwrng built on the chip automatically,yet the user has to know how to setup rngd and deal with the fact that if you put the interface down, rngd will go kaput. :|
This is the epitome of user-unfriendlyness, yet pretty much everything uses entropy in one way of other,without the user having a single clue about it.
That sounds more like a problem with rngd if the it dies when the interface goes down.
