Needs a commit comment, documenting compat issues (newer client talking to older server; older client talking to newer server). See my email on v1 about how I think we also need the addition of a new flag, and that no hypervisor driver will send a string unless the new flag is present to say strings are safe.

Can s legitimately be NULL, or is it guaranteed to be non-NULL?

      } value; /* parameter value */
  };

If s can be NULL, this will crash. If s cannot be NULL, then where to we validate it?
