selftests/bpf: Test referenced kptr arguments of struct_ops programs 2025-02-18T02:47:27+00:00 Amery Hung amery.hung@bytedance.com 2025-02-17T19:06:38+00:00 6991ec6beb262b8c21ba3ee1992d7e81d8203769 Test referenced kptr acquired through struct_ops argument tagged with "__ref". The success case checks whether 1) a reference to the correct type is acquired, and 2) the referenced kptr argument can be accessed in multiple paths as long as it hasn't been released. In the fail cases, we first confirm that a referenced kptr acquried through a struct_ops argument is not allowed to be leaked. Then, we make sure this new referenced kptr acquiring mechanism does not accidentally allow referenced kptrs to flow into global subprograms through their arguments.
