Webhash. ) Get or create a Flow using a FlowKey. Hash retrieval function for flows. Looks up the hash bucket containing the flow pointer. Then compares the packet with the found flow to see if it is the flow we need. If it isn't, walk the list until the right flow is found. Return a new Flow if ever no Flow was found. WebApr 22, 2024 · FlowGetFlowFromHash 函数的主要逻辑:用hash值经过计算作为索引,从流表中获取一个 FlowBucket 的指针。 若head为空,说明还没有流,调用 FlowGetNew 分配一个新的流;若head不为空,则bucket中有流,尝试从Flow链表中查找该packet所属的流。 WebThe http.log output module uses inefficient locking logic. It does expensive operations while holding a global output lock, resulting in lots of contention and very long lock wait times: flashback quilt pattern
