2024-05-09net: hns3: fix kernel crash when devlink reload during initializationYonglong Liu1-6/+4
The devlink reload process will access the hardware resources, but the register operation is done before the hardware is initialized. So, processing the devlink reload during initialization may lead to kernel crash. This patch fixes this by registering the devlink after hardware initialization.

There is a memory barrier in followed case. When set the port down, hclgevf_set_timmer will set DOWN in state. Meanwhile, the service task has different behaviour based on whether the state is DOWN.

2023-11-13net: hns3: fix VF reset fail issueJijie Shao1-1/+13
Currently the reset process in hns3 and firmware watchdog init process is asynchronous. We think firmware watchdog initialization is completed before VF clear the interrupt source. However, firmware initialization may not complete early. So VF will receive multiple reset interrupts and fail to reset. So we add delay before VF interrupt source and 5 ms delay is enough to avoid second reset interrupt.

The hclge_sync_vlan_filter is called in periodic task, trying to remove VLAN from vlan_del_fail_bmap. It can be concurrence with VLAN adding operation from user. So once user failed to delete a VLAN id, and add it again soon, it may be removed by the periodic task, which may cause the software configuration being inconsistent with hardware.

Currently, when PF set VF VLAN, it sends notify mailbox to VF if VF alive. VF stop its traffic, and send request mailbox to PF, then PF updates VF VLAN. It's a bit complex. If VF is killed before sending request, PF will not set VF VLAN without any log. This patch refines the process, PF can set VF VLAN direclty, and then notify the VF. If VF is resetting at that time, the notify may be dropped, so VF should query it after reset finished.

Currently, the workqueue of hclge/hclgevf is executed on the CPU that initiates scheduling requests by default. In stress scenarios, the CPU may be busy and workqueue scheduling is completed after a long period of time. To avoid this situation and implement proper scheduling, use the WQ_UNBOUND mode instead. In this way, the workqueue can be performed on a relatively idle CPU. Signed-off-by: Yufeng Mo <moyufeng@huawei.com> Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S.

2021-10-20net: hns3: fix vf reset workqueue cannot exitYufeng Mo1-3/+3
The task of VF reset is performed through the workqueue. It checks the value of hdev->reset_pending to determine whether to exit the loop. However, the value of hdev->reset_pending may also be assigned by the interrupt function hclgevf_misc_irq_handle(), which may cause the loop fail to exit and keep occupying the workqueue. This loop is not necessary, so remove it and the workqueue will be rescheduled if the reset needs to be retried or a new reset occurs.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski1-1/+1
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

2021-09-13net: hns3: fix the timing issue of VF clearing interrupt sourcesJiaran Zhang1-3/+3
Currently, the VF does not clear the interrupt source immediately after receiving the interrupt. As a result, if the second interrupt task is triggered when processing the first interrupt task, clearing the interrupt source before exiting will clear the interrupt sources of the two tasks at the same time. As a result, no interrupt is triggered for the second task. The VF detects the missed message only when the next interrupt is generated. Clearing it immediately after executing check_evt_cause ensures that: 1. Even if two interrupt tasks are triggered at the same time, they can be processed. 2. If the second task is triggered during the processing of the first task and the interrupt source is not cleared, the interrupt is reported after vector0 is enabled.
