H A D | modify_return.c | 3d08b6f2 Wed Mar 04 13:18:53 CST 2020 KP Singh <kpsingh@google.com> bpf: Add selftests for BPF_MODIFY_RETURN
Test for two scenarios:
* When the fmod_ret program returns 0, the original function should be called along with fentry and fexit programs. * When the fmod_ret program returns a non-zero value, the original function should not be called, no side effect should be observed and fentry and fexit programs should be called.
The result from the kernel function call and whether a side-effect is observed is returned via the retval attr of the BPF_PROG_TEST_RUN (bpf) syscall.
