The full allocation length is then copied to the wire by nvmet_copy_to_sgl(), so a remote initiator receives the bytes past the built message -- up to nearly a page of uninitialized slab -- during the pre-authentication handshake. Allocate the buffer with kzalloc() so the unwritten tail is zeroed before it is sent; conforming responses are unaffected.
