Hi!

well, the situation for external modules is no worse than usual.
They still work, they just aren't signed. Which from a distributor point
of view, is actually a nice thing, as they stick out like a sore thumb
in oops reports with (U) markers :)
I agree, that's really what should happen. We solve this by marking modules as 
supported, partner supported, or unsupported, but in an "insecure" way, so 
partners and users could try to fake the support status of a module and/or 
remove status flags from Oopses, and cryptography wouldn't save us. We could 
try to sign Oopses which I guess you guys are doing. This whole issue hasn't 
I do not think any ammount of crypto can determine that I loaded
unsupported module, then edited oops. (TPM hw module may be able to do that, not
sure).
