Looks to be the same reason as sendto().
I'm thinking we can either remove that test or change it to UDP:

diff --git a/testcases/kernel/syscalls/sendto/sendto01.c b/testcases/kernel/syscalls/sendto/sendto01.c
index ad64c70..c8dd9bd 100644
--- a/testcases/kernel/syscalls/sendto/sendto01.c
+++ b/testcases/kernel/syscalls/sendto/sendto01.c
@@ -126,8 +126,8 @@ struct test_case_t {                /* test case structure */
                    sizeof(sin1), -1, EPIPE, setup2, cleanup1,
                    "local endpoint shutdown"}
        , {
-       PF_INET, SOCK_STREAM, 0, buf, sizeof(buf), -1, &sin1,
-                   sizeof(sin1), 0, EPIPE, setup1, cleanup1,

                    "invalid flags set"}
 };

this way it should hit:
        if (msg->msg_flags&MSG_OOB)     /* Mirror BSD error message compatibility */
                return -EOPNOTSUPP;

I see the check is there at least since 2.6.11.
Any thoughts?
