Subject: [PATCH] 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);
