From 02f58e5bf2e98bf7543019d7bba21f83ff8abb13 Mon Sep 17 00:00:00 2001 From: Devulapally Shiva Krishna Date: Tue, 5 May 2020 08:42:57 +0530 Subject: [PATCH] Crypto/chcr: fix for hmac(sha) test fails The hmac(sha) test fails for a zero length source text data. For hmac(sha) minimum length of the data must be of block-size. So fix this by including the data_len for the last block.
