Descriptions

In the Linux kernel, the following vulnerability has been resolved:

net: hns3: fix a deadlock problem when config TC during resetting

When config TC during the reset process, may cause a deadlock, the flow is
as below:
pf reset start


......
setup tc │
│ ▼
▼ DOWN: napi_disable()
napi_disable()(skip) │
│ │
▼ ▼
...... ......
│ │
▼ │
napi_enable() │

UINIT: netif_napi_del()


......


INIT: netif_napi_add()


...... global reset start
│ │
▼ ▼
UP: napi_enable()(skip) ......
│ │
▼ ▼
...... napi_disable()

In reset process, the driver will DOWN the port and then UINIT, in this
case, the setup tc process will UP the port before UINIT, so cause the
problem. Adds a DOWN process in UINIT to fix it.
