From 505d949dcb6b756f6db6588d3425d9cd6108c77f Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/3] test: Be sure to terminate strncpy() copied string
(-Wstringop-truncation)
strncpy() might not NULL-terminate the buffer. This fixes GCC v8.1.0 warning:
test/kcapi-main.c: In function 'main':
test/kcapi-main.c:3123:5: error: 'strncpy' specified bound 63 equals destination size [-Werror=stringop-truncation]
strncpy(cavs_test.cipher, optarg,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
CIPHERMAXNAME);
~~~~~~~~~~~~~~
