[PATCH] staging: usbip: stub_main.c: Cleaning up missing null-terminate after strncpy call

[Rickard Strandqvist]

Hi

True!
Sorry  :-(

But then one would either operate strcpy outright.

Or use strlcpy then the code would be:

    /* strlcpy() handles not include \0 */
    len = strlcpy(busid, buf + 4, BUSID_SIZE);

    /* busid needs to include \0 termination */
    if (!(len < BUSID_SIZE))
        return -EINVAL;


Or should we just let it be, perhaps?


Kind regards
Rickard Strandqvist
