Currently, when function hns3_nic_select_queue() converts dscp to priority, it calls an indirect callback ae_algo->ops->get_dscp_prio to get priority. However as function hns3_nic_select_queue() is in fast path, the indirect call may cause degradation of performance. For optimization, this patch moves dscp_app_cnt and dscp_prio from struct hclge_tm_info to struct hnae3_knic_private_info, so they can be used in both hclge and hns3 layers. Signed-off-by:

Now, register_pernet_subsys() and register_netdevice_notifier() are both after sock_register(). It can create PF_PACKET socket and process socket once sock_register() successfully. It is possible PF_PACKET socket is creating but register_pernet_subsys() and register_netdevice_notifier() are not registered yet. Thus net->packet.sklist_lock and net->packet.sklist will be accessed without initialization that is done in packet_net_init(). Although this is a low probability scenario. Move register_pernet_subsys() and register_netdevice_notifier() to the front in packet_init(). Correspondingly, adjust the unregister process in packet_exit(). Signed-off-by:

Zhengchao Shao says: ==================== refactor duplicate codes in the tc cls walk function The walk implementation of most tc cls modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. Then use helper function to replace the code of each cls module in alphabetical order. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. ==================== Link: https://lore.kernel.org/r/20220916020251.190097-1-shaozhengchao@huawei.comSigned-off-by:

Since commit 13511704 ("net: taprio offload: enforce qdisc to netdev queue mapping"), taprio_dequeue_soft() and taprio_peek_soft() are de facto the only implementations for Qdisc_ops :: dequeue and Qdisc_ops :: peek that taprio provides. This is because in full offload mode, __dev_queue_xmit() will select a txq->qdisc which is never root taprio qdisc. So if nothing is enqueued in the root qdisc, it will never be run and nothing will get dequeued from it. Therefore, we can remove the private indirection from taprio, and always point Qdisc_ops :: dequeue to taprio_dequeue_soft (now simply named taprio_dequeue) and Qdisc_ops :: peek to taprio_peek_soft (now simply named taprio_peek).

Since commit 13511704 ("net: taprio offload: enforce qdisc to netdev queue mapping"), __dev_queue_xmit() will select a txq->qdisc for the full offload case of taprio which isn't the root taprio qdisc, so qdisc enqueues will never pass through taprio_enqueue(). That commit already introduced one safety precaution check for FULL_OFFLOAD_IS_ENABLED(); a second one is really not needed, so simplify the conditional for entering into the GSO segmentation logic. Also reword the comment a little, to appear more natural after the code change. Signed-off-by:

Since the writer-side lock is taken here, we do not need to open an RCU read-side critical section, instead we can use rtnl_dereference() to tell lockdep we are serialized with concurrent writes. Signed-off-by:

Vladimir Oltean authored
The locking in taprio_offload_config_changed() is wrong (but also inconsequentially so). The current_entry_lock does not serialize changes to the admin and oper schedules, only to the current entry. In fact, the rtnl_mutex does that, and that is taken at the time when taprio_change() is called. Replace the rcu_dereference_protected() method with the proper RCU annotation, and drop the unnecessary spin lock. Signed-off-by:
