Then *mp keeps the invalid pointer and it might be used. Fix the potential use after free and also reset *mp in other places to have less dangling pointers to freed mbufs.

It is more consistent to have less different structures. The divert_input functions cannot be called anyway, so remove them. OK visa@ mpi@
