From: Devulapally Shiva Krishna <shiva@xxxxxxxxxxx> [ 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.
