How about relevant xattrs? SELinux context, ACL, that sort of thing.
The fact that these are optional should be taken care of by (4).
Those are not simple, fixed size stat data and would make the system

I didn't say it would be easy. I do think that adding a system call
that only deals with simple, fixed size data is going to fall short
of solving "the problem".
Actually, a Smack label is fixed size (256 bytes). I suspect there
is a maximum for SELinux contexts as well. ACLs I'll grant you are
infinite.
