I changed the testcase, and it was passable after that.

static struct test_case tcase[] = {
    {
        .desc = "NORMAL",
        .qname = QUEUE_NAME,
        .oflag = O_CREAT,
        .rq = &(struct mq_attr){.mq_maxmsg = 10, .mq_msgsize = 8192},
        .ret = 0,
        .err = 0,
    }
};

But when I change mq_maxmsg and mq_maxsize, it doesn't pass the test, it seems that the changes don't take effect.

You are using old LTP. Although mq_open01.c was not modified since (20230929), generally it's recommended to use the latest release or current master branch.

It's hard knowing without the details about the system to see whether it's a test failure or kernel failure.
