From ec19b7a525aa3f5dc1c82a514d6d020b46e786ce Mon Sep 17 00:00:00 2001 From: Devulapally Shiva Krishna Date: Tue, 5 May 2020 08:42:55 +0530 Subject: [PATCH] Crypto/chcr: fix for ccm(aes) failed test [ Upstream commit 10b0c75d7bc19606fa9a62c8ab9180e95c0e0385 ] The ccm(aes) test fails when req->assoclen > ~240bytes. The problem is the value assigned to auth_offset is wrong. As auth_offset is unsigned char, it can take max value as 255. So fix it by making it unsigned int.
