2021-04-16bpf: Update selftests to reflect new error statesDaniel Borkmann1-13/+0
Update various selftest error messages: * The 'Rx tried to sub from different maps, paths, or prohibited types' is reworked into more specific/differentiated error messages for better guidance. * The change into 'value -4294967168 makes map_value pointer be out of bounds' is due to moving the mixed bounds check into the speculation handling and thus occuring slightly later than above mentioned sanity check. * The change into 'math between map_value pointer and register with unbounded min value' is similarly due to register sanity check coming before the mixed bounds check. * The case of 'map access: known scalar += value_ptr from different maps' now loads fine given masks are the same from the different paths (despite max map value size being different).

2019-01-27selftests: bpf: break up test_verifierJakub Kicinski1-0/+406
Break up the first 10 kLoC of test verifier test cases out into smaller files. Looks like git line counting gets a little flismy above 16 bit integers, so we need two commits to break up test_verifier.
