Using mpcsec driver without io-pkt   
Hello!



I would like to make use of the mpcsec driver, but I'm using QNX 6.3.0SP3 and therefore not the latest io-pkt version.

Is there any possibility to build the driver without building the whole packet?

Thank you very much in advance.



Markus

How do I build drivers under 6.4.0 without downloading all of the io-pkt source base?

We've changed the driver building under 6.4.1 so that headers that were previously available only as part of the source 
package are now installed as part of the system headers. These headers will be included in an upcoming 6.4.0.1 
maintenance patch. In the interim, the appropriate headers are available in the attachment at the bottom of this page.

Under windows, run bash to get a bash shell first. On linux and self-hosted, make sure that you've got root access

 
cd $(QNX_TARGET)/usr/include

 
gzip -d _path_to_/iopkt_build_headers.tar.gz

tar -xvf _path_to/iopkt_build_headers.tar


(Under bash with windows, if you want to specify the full path including the disk name, use /c/ to prefix the directory 
name)


These headers should be installed under your QNX_TARGET/usr/include directory (you'll end up with a QNX_TARGET/usr/
include/io-pkt subdirectory containing all of the header files).

 

A build directory can be created by placing the Makefile and prodroot.mk files from trunk/sys/dev_qnx into a top level 
directory and adding driver sub-directories below it as follows:

 

top_dir/

    Makefile

    prodroot.mk

    driver_1/

         driver_1 source, Makefile, cpu variants, etc.

    driver_2/

         driver_2 source, Makefile, cpu variants, etc.

Hope this helps,
Jeevan

He'll still end up with an io-pkt driver though
that won't work under io-net.

Ya, why not running io-pkt under QNX630 unthinkable ?

It's probably possible (I've never tried it); but from
his first post I got the impression he was stuck at
io-net (I could be wrong ...).

Re: Using mpcsec driver without io-pkt   
Yes, unfortunately there's currently too much involved in switching to io-pkt.
But nevertheless thanks for all your hints.

My idea was to use the mpcsec hardware encryption for OpenSSL, similar to what a colleague has already tried before, but
 without building the whole packet:
http://community.qnx.com/sf/go/projects.networking/discussion.builds.topc2097
Instead, I would try to build a stand-alone library of OpenSSL which makes direct use of the mpcsec.

But I gradually reckon that adapting the OpenSSL sources and "cutting" the mpcsec out of the io-pkt requires too much 
effort to be realistically feasible if you're not a QNX PPC SEC OpenSSL guru...

Just out of curiousness:
Wouldn't it be in general desirable to have OpenSSL running on ppc hardware with SEC support, doing real hardware 
encryption? Has anyone tried that before?
