In my case, there are two process sharing hugepage memory£¨struct rte_acl_ctx£©, one process call 'rte_acl_build' to add and apply rule, another process call frequently 'rte_acl_classify' to match rule, does it need to add lock? if not, is there other method to implement this safely?

Yes.

Just add new rules is safe, but applying them (calling rte_acl_build()) is not.
