           Summary: nfp: duplicate call to rte_free
           Product: DPDK
           Version: 24.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal

          Reporter: stephen at networkplumber.org
  Target Milestone: ---

This function nfp_pre_tun_table_check_del in nfp_flower_flow.c could call
rte_free twice on the same pointer.

static int
nfp_pre_tun_table_check_del(struct nfp_flower_representor *repr,
                struct rte_flow *nfp_flow)
{
...
        rte_free(entry);
        rte_free(find_entry);
        priv->pre_tun_cnt--;

free_entry:
        rte_free(entry);        << already freed above

        return ret;
}
