Hi Niko,
- I use cryptodev 1.5.
- You are right, I missed that point in the code, it comes from
cryptodev_hash_final, so areq->src should be NULL. Now my questions come to why
talitos chooses areq->src for psrc (depends on req_ctx->count). I will check it
out and I will come back to you, if necessary, next week.
Thank you for your immediate reply.
Kind Regards/Με ευχές
Nikolaos Tsakalakis
