(In reply to Alexandre martins from comment #4)

It seems that the cession is not thread safe, for example in cryptodev_op:

 ...
 712         cse->uio.uio_iov = &cse->iovec;
 713         cse->uio.uio_iovcnt = 1;
 714         cse->uio.uio_offset = 0;
 ...     

There is no lock around that.

Should I propose a bigger patch to fix that ?
