| 2024-12-14 | selftests/bpf: Add tests for raw_tp NULL args | Kumar Kartikeya Dwivedi | 1 | -0/+3 | |
| Add tests to ensure that arguments are correctly marked based on their specified positions, and whether they get marked correctly as maybe null. For modules, all tracepoint parameters should be marked PTR_MAYBE_NULL by default.

| 2024-11-04 | selftests/bpf: Add tests for raw_tp null handling | Kumar Kartikeya Dwivedi | 1 | -0/+25 | |
| Ensure that trusted PTR_TO_BTF_ID accesses perform PROBE_MEM handling in raw_tp program. Without the previous fix, this selftest crashes the kernel due to a NULL-pointer dereference. Also ensure that dead code elimination does not kick in for checks on the pointer.
