Is it possible to compile Infinite Noise for OpenBSD?

[barntop47]

Has anyone heard of Infinite Noise?

This device sounds very promising but I'm disappointed that there doesn't seem to be any actual OpenBSD drivers for it?

So I suppose the only option is to compile the source code into an OpenBSD app? Is that right?

Right?

No, I never have heard of it. For English speakers see https://github.com/leetronics/infnoise

As far as I understand it takes over /dev/random I don't know whether that is a good idea. OpenBSD developers don't allow external stuff linking into the kernel, That is why for example PAM modules are not supported.

Some time ago I saw a presentation of Theo de Raadt about randoms number generators in OpenBSD : Randomness: how arc4random has grown since 1998

• OpenBSD uses a monolithic kernel. All hardware drivers must be part of the compiled kernel, external kernel modules cannot be used.
• A quick keyword search through the OpenBSD mailing list archives didn't come up with any mention of this driver.

If you want this driver in the OS, you will have to adapt it into and integrate it with the OpenBSD kernel.

Correction - there was a discussion 2 years ago on misc@; this "driver" may be able to run in userland.
