Doing this will result in a -EBUSY return code from rte_service_lcore_stop() which the service_attr_get subtest was not checking. This left the service lcore running, and a race existed with the main lcore on checking the service attributes which triggered this CI failure. To fix this, dissociate the service lcore with current service. Once fixed this first issue, a race still exists, because the wait_slcore_inactive helper added in a previous fix was not paired with a check that the service lcore _did_ stop. Add missing check on rte_service_lcore_may_be_active. Fixes: |
