The previous libbpf patch allows user to specify "prog_flags" to bpf program load APIs. To enable high 32-bit randomization for a test, we need to set BPF_F_TEST_RND_HI32 in "prog_flags". To enable such randomization for all tests, we need to make sure all places are passing BPF_F_TEST_RND_HI32. Changing them one by one is not convenient, also, it would be better if a test could be switched to "normal" running mode without code change. Given the program load APIs used across bpf selftests are mostly: bpf_prog_load: load from file bpf_load_program: load from raw insns A test_stub.c is implemented for bpf seltests, it offers two functions for testing purpose: bpf_prog_test_load bpf_test_load_program The are the same as "bpf_prog_load" and "bpf_load_program", except they also set BPF_F_TEST_RND_HI32. Given *_xattr functions are the APIs to customize any "prog_flags", it makes little sense to put these two functions into libbpf. Then, the following CFLAGS are passed to compilations for host programs: -Dbpf_prog_load=bpf_prog_test_load -Dbpf_load_program=bpf_test_load_program They migrate the used load APIs to the test version, hence enable high 32-bit randomization for these tests without changing source code. Besides all these, there are several testcases are using "bpf_prog_load_attr" directly, their call sites are updated to pass BPF_F_TEST_RND_HI32.
