Hi Corentin, I am fine with this proposal: it is generic enough and I have been able to test and run the crypto engine with aead_request without changing any single line of code. This is what I need to be able to send the AEAD extension of the stm32-cryp driver (successfully tested with your engine upgrade proposal). I have also tested the stm32-hash patch. Note that stm32-cryp (new driver applied by Herbert recently [https://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git/commit/?id=9e054ec21ef8344345b28603fb272fe999f735db]) would also need to be converted to the new crypto engine API : this is a trivial patch. Thank you for your proposal, I hope that this proposal is fine for Herbert too.
