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.
