From ae748b9cf852833d121cf0c1d35bff52d566102b Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Mon, 17 Jun 2019 10:18:48 +0200 Subject: wusb: switch to cbcmac transform The wusb code takes a very peculiar approach at implementing CBC-MAC, by using plain CBC into a scratch buffer, and taking the output IV as the MAC. We can clean up this code substantially by switching to the cbcmac shash, as exposed by the CCM template. To ensure that the module is loaded on demand, add the cbcmac template name as a module alias.
