Adding more bits to the pool should never hurt; the cryptographic mixing ensures this. What _can_ hurt is adding predictable bits but (erroneously) bumping up the entropy counter.
So, if you're not sure whether those bits are unpredictable and random or not, the right thing to do is to mix 'em into the pool, but don't bump the entropy counter. The greater your diversity of sources, the less likely it is that you encounter a catastrophic randomness failure. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
