rte_metrics_reg_names() relies on cnt_names being truthful about the size of *names. If it is overstated there is nothing to prevent an array overrun and in most cases a core-dump.

Ditto.

Updates cannot overlap more than one metric set. A successful test would be: /* Success Test: valid data */ err = rte_metrics_update_values(RTE_METRICS_GLOBAL, 0, &value[0], 1); TEST_ASSERT(err >= 0, "%s, %d", __func__, __LINE__); err = rte_metrics_update_values(RTE_METRICS_GLOBAL, 1, &value[1], 1); TEST_ASSERT(err >= 0, "%s, %d", __func__, __LINE__); err = rte_metrics_update_values(RTE_METRICS_GLOBAL, 2, &value[2], 4); TEST_ASSERT(err >= 0, "%s, %d", __func__, __LINE__); I am wondering whether this constraint should be removed.

Good catch. Will update library code.

KEY should be 2, which is where the set of size four starts. The set starting at KEY (i.e 1) is of size one.
+ + /* Failed Test: Invalid port_id(lower value) and valid data */ + err = rte_metrics_update_values(-2, KEY, &value[0], ARRAY_SIZE(value)); + TEST_ASSERT(err == -EINVAL, "%s, %d", __func__, __LINE__); + + /* Failed Test: Invalid port_id(higher value) and valid data */ + err = rte_metrics_update_values(39, 1, &value[0], ARRAY_SIZE(value)); + TEST_ASSERT(err == -EINVAL, "%s, %d", __func__, __LINE__);
Testcases Ok.
+ + /* Failed Test: higher count size */ + err = rte_metrics_update_values(RTE_METRICS_GLOBAL, + KEY, &value[0], ARRAY_SIZE(value) + 5); + TEST_ASSERT(err == -ERANGE, "%s, %d", __func__, __LINE__);
Array sizes should not be overstated.

Overstated array size.

Overstated array size.
