From 7aacbfcb331ceff3ac43096d563a1f93ed46e35e Mon Sep 17 00:00:00 2001 From: Robert Baronescu Date: Tue, 10 Oct 2017 13:22:00 +0300 Subject: crypto: tcrypt - fix buffer lengths in test_aead_speed() Fix the way the length of the buffers used for encryption / decryption are computed. For e.g. in case of encryption, input buffer does not contain an authentication tag.
