hmmm... I just got a message from chris, he said he will be adding AES/Rijndael to the kernel ASAP...

According to the Rijndael spec, it seems to also function as an excellant pseudo-random number generator...

You can find this info at:

http://www.esat.kuleuven.ac.be/~rijmen/rijndael

Section 13.4 of the Rijndael Block Cipher AES Proposal [version 2], describes this functionality. Based on the benchmark times of this process, I don't think it would be a serious performance hit to do this. If it's going to be in the kernel anyway...

Just a constructive suggestion.

In reply:

In real life, machines don't always get rebooted in a completely controlled fashion (panic, power failure, etc.). Anything that makes a reboot longer or less reliable is a definite non-starter.

I can guarantee you, if the current /dev/random code isn't fixed before it makes STABLE, folks running servers 24/7 are going to rip it right out.
