selftests/bpf: add test for bogus operations on pointers · c2c3e117

Edward Cree authored Aug 07, 2017



Tests non-add/sub operations (AND, LSH) on pointers decaying them to
 unknown scalars.
Also tests that a pkt_ptr add which could potentially overflow is rejected
 (find_good_pkt_pointers ignores it and doesn't give us any reg->range).
