gonzo 9e141fd88f Fix off-by-one error in BERI virtio driver ... The hardcoded ident is exactly 20 bytes long but sprintf adds terminating zero, so there is one byte written out of array bounds.As a fix use strncpy it appends \0 only if space allows and its behavior matches virtio spec: When VIRTIO_BLK_T_GET_ID is issued, the device identifier, up to 20 bytes, is written to the buffer. The identifier should be interpreted as an ascii string. It is terminated with \0, unless it is exactly 20 bytes long.
