Maxim Mikityanskiy b560b21f71 bpf: Add selftests to cover packet access corner cases ... This commit adds BPF verifier selftests that cover all corner cases by packet boundary checks. Specifically, 8-byte packet reads are tested at the beginning of data and at the beginning of data_meta, using all kinds of boundary checks (all comparison operators: <, >, <=, >=; both permutations of operands: data + length compared to end, end compared to data + length). For each case there are three tests: 1. Length is just enough for an 8-byte read. Length is either 7 or 8, depending on the comparison. 2. Length is increased by 1 - should still pass the verifier. These cases are useful, because they failed before commit 2fa7d94afc ("bpf: Fix the off-by-two error in range markings"). 3. Length is decreased by 1 - should be rejected by the verifier. Some existing tests are just renamed to avoid duplication.
