From 65bf43424df4688215ba6f2bfa5d00fca3b3f481 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Mon, 27 May 2019 16:51:01 +0200 Subject: [PATCH] crypto: inside-secure - fix zeroing of the request in ahash_exit_inv [ Upstream commit b926213d6fede9c9427d7c12eaf7d9f0895deb4e ] A request is zeroed in safexcel_ahash_exit_inv(). This request total size is EIP197_AHASH_REQ_SIZE while the memset zeroing it uses sizeof(struct ahash_request), which happens to be less than EIP197_AHASH_REQ_SIZE. This patch fixes it.
