Commit Message

Menglong Dong June 19, 2023, 11:49 a.m. UTC 
From: Menglong Dong <imagedong@tencent.com>

Add test9/test10 in fexit_test.c and fentry_test.c to test the fentry
and fexit whose target function have 7/11 arguments.

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:

./test_progs -t fexit
Summary: 5/12 PASSED, 0 SKIPPED, 0 FAILED

./test_progs -t fentry
Summary: 3/0 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

v6:
- add testcases to tracing_struct.c instead of fentry_test.c and
  fexit_test.c
v5:
- add testcases for MODIFY_RETURN
v4:
- use different type for args in bpf_testmod_fentry_test{7,12}
- add testcase for grabage values in ctx
v3:
- move bpf_fentry_test{7,12} to bpf_testmod.c and rename them to
  bpf_testmod_fentry_test{7,12} meanwhile
- get return value by bpf_get_func_ret() in
  "fexit/bpf_testmod_fentry_test12", as we don't change ___bpf_ctx_cast()
  in this version
