When compiling, the following warning message is generated: "warning: ‘strncpy’ writing 1040 bytes into a region of size 1024 overflows the destination" This is because calloc allocates NLMSG_SPACE(MAX_PAYLOAD) space for nlh, which includes the space for the header, so the actual space available for the message is only MAX_PAYLOAD.
