From: Eric Biggers Date: Thu, 19 Oct 2023 05:53:35 +0000 (-0700) Subject: crypto: vmac - don't set alignmask X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1fb90689bc7ced529152fec406faddd0bcbf99f1;p=linux.git crypto: vmac - don't set alignmask The vmac template is setting its alignmask to that of its underlying 'cipher'. This doesn't actually accomplish anything useful, though, so stop doing it. (vmac_update() does have an alignment bug, where it assumes u64 alignment when it shouldn't, but that bug exists both before and after this patch.) This is a prerequisite for removing support for nonzero alignmasks from shash.
