2021-11-05unittest: gcc-11 errors for clib_strcpy, clib_strstr, clib_strcat, and ↵Steven Luong2-385/+30
clib_strncat There are 3 versions of the string functions. For example, for strcpy, they are 1. strcpy(dst, src) -- the legacy unsafe version 2. strcpy_s(dst, dmax, src) -- C11 safeC version which has an addition argument named dmax. 3. clib_strcpy(dst,src) -- clib version to enable legacy code that uses strcpy to make use of strcpy_s without adding the additional argument, dmax, which is required by the C11 safeC version. The implementation for the clib version is to artificially provide dmax to strcpy_s. In this case, it uses 4096 which assumes that if the legacy code works without blowing up, it is likely to work with the clib version without problem. gcc-11 is getting smarter by checking if dmax is within the object's boundary. When the object is declared as static array, it will flag a warning/error if dmax is out of bound for the object since the real size of dst can be determined at compile time. There is no way to find the real size of dst if the object is dynamically allocated at compile time. For this reason, we simply can't provide support for the clib version of the function anymore. If any code is using the clib version, the choice is to migrate to the safeC version.

Type: fix Fixes: d96b28ac0917 ("virtio: improve input node performance") vlib_buffer_t is defined on stack to be used for input feature arc lookup once per frame call for performance reasons.
