MPC885 CryptoApi support.

MPC885 CryptoApi support.

[Guillaume Autran]

Hi,

Is there any open source development done to integrate the MPC885 
security coprocessor into the linux 2.6 kernel CryptoApi framework ?
Did anyone wrote a driver for it yet ?

Best regards,
Guillaume.

Current kernel CryptoAPI is lacking sane support for hw crypto engines 
(e.g. there is no async crypto). Until there is such generic support, 
it's highly difficult to efficiently integrate hw crypto into the 
kernel. I did such stuff for Hifn 7955 accelerator and didn't like the 
result :).

Thanks Eugene,
Do you know if anybody is working on HW crypto engine support ?

There were some patches posted to lkml around a month or so ago. Don't 
know what happened to them.

Guillaume:

Arabella Software provides asynchronous 2.6 kernel CryptoApi support for the
MPC885 as well as the PowerQUICC II devices as part of our commercially
supported Linux distribution. If you would be interested in a commercial
open source offering, please feel free to contact me and I can provide
further detail.

Best Regards,

Bruce

These drivers are not GPL, then? 

RE: MPC885 CryptoApi support.

[Autran, Guillaume]

Not sure. It seems that not all of the Linux kernel source they modified is
freely available. The "free" evaluation kit only contains an old version of
2.4.x kernel and definitely, no support for the MPC885 SEC-Lite.
So, unless they rewrote the all thing, I don't understand how it could be...

[Bruce Donadt]

Guillaume and Marcelo:

My post on this list about Arabella's support for the PQ1 and PQ2 on board
security device as well as the enhancements we have made to CryptoApi and
IPsec was meant to be just a quick note to those interested that there is a
solution available although it is a commercial solution. I am reluctant to
continue a discussion about a commercial offering in this forum. You may
feel free to contact me directly with further questions.

To answer the original question. The code is provided under a GPL license to
companies that purchase a subscription to the Arabella Linux distribution.
We have invested many man months in developing a commercial grade security
solution for the PowerQUICCs and all of it has been written from the ground
up. You are correct when you say that none of this is included in our "free"
evaluation kit.

Best Regards,

Bruce

Don't mean to start an argument or unnecessarily continue a discussion, 
Bruce, but, GPL=/the right to fork/.

If it is the case that you have provided a GPL-Arabella-Linux-Kernel, to 
a customer and all the code is GPL compliant, then that customer, is 
*free* to fork and/or redistribute that code, which seems like a bit of 
an oxymoron, for a commercial offering !

Maybe we should start a collect to buy one "license" and put it on  a
FTP server :-)

Sure, and while we're at it, why not do the same for MontaVista kernel, 
Metrowerks kernel, etc...
