From ba1ee070909fae01248b8117da1706f3cf2bfd1b Mon Sep 17 00:00:00 2001 From: Salman Qazi Date: Fri, 5 Oct 2012 14:24:14 -0700 Subject: crypto: vmac - Make VMAC work when blocks aren't aligned VMAC implementation, as it is, does not work with blocks that are not multiples of 128-bytes. Furthermore, this is a problem when using the implementation on scatterlists, even when the complete plain text is 128-byte multiple, as the pieces that get passed to vmac_update can be pretty much any size. I also added test cases for unaligned blocks.
