Doing strncpy(ifr.ifr_name, s, sizeof(ifr.ifr_name)) will cause

Fix this by using sizeof(ifr.ifr_name) - 1. Also, there is no

Given n equals to the maximum number of bytes to copy from src in the API,
or the rough estimate strlen of src, strncpy_s_inline should not copy more
than the number of bytes, computed by strlen(src), to dst if n is greater than
strlen(src). The number of bytes to copy is computed by strnlen(src,n), not n.
