We are also looking for user-space access to the kernel crypto layer compression algorithms. I have gone through AF_ALG but couldn’t find support for compression ops through it. This is required for our hardware zip engines whose driver hooks up to the crypto layer. I was going through the lists and stumbled across this thread. Has there been any updates or efforts put up in this direction since this thread is a few years old. If not, are there any alternate implementations that allow user-space access to compression? I have gone through cryptodev and see the same limitation there. Would appreciate any pointers in this regard.
