            Bug ID: 446
           Summary: rte_lcore_index(-1) returns invalid data for non DPDK
                    thread.
           Product: DPDK
           Version: 20.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev at dpdk.org
          Reporter: stephen at networkplumber.org
  Target Milestone: ---

Calling rte_lcore_index() with -1 as lcore returns the relative index of the
current lcore in the cpuset.  But if called from a non-DPDK thread the value is
undefined. It ends up referencing outside lcore_config array and gets some
other value.  In our tests it got 253; but could be anything.

It is documented to return -1 on error. It does that if passed an lcore value
outside the cpu set, it should return -1 if run in non-DPDK thread as well.
