selftests/bpf: add testcase for TRACING with 6+ arguments Add fentry_many_args.c and fexit_many_args.c to test the fentry/fexit with 7/11 arguments. As this feature is not supported by arm64 yet, we disable these testcases for arm64 in DENYLIST.aarch64. We can combine them with fentry_test.c/fexit_test.c when arm64 is supported too. Correspondingly, add bpf_testmod_fentry_test7() and bpf_testmod_fentry_test11() to bpf_testmod.c Meanwhile, add bpf_modify_return_test2() to test_run.c to test the MODIFY_RETURN with 7 arguments. Add bpf_testmod_test_struct_arg_7/bpf_testmod_test_struct_arg_7 in bpf_testmod.c to test the struct in the arguments. And the testcases passed on x86_64: ./test_progs -t fexit Summary: 5/14 PASSED, 0 SKIPPED, 0 FAILED ./test_progs -t fentry Summary: 3/2 PASSED, 0 SKIPPED, 0 FAILED ./test_progs -t modify_return Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED ./test_progs -t tracing_struct Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Menglong Dong <imagedong@tencent.com> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/r/20230713040738.1789742-4-imagedong@tencent.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

selftests/bpf: Add test to access integer type of variable array Add prog test for accessing integer type of variable array in tracing program. In addition, hook load_balance function to access sd->span[0], only to confirm whether the load is successful. Because there is no direct way to trigger load_balance call.
