Description

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.

Affected configurations

• linux linux kernel (>= 4.15 < 5.4.283) • linux linux kernel (>= 5.5 < 5.10.225) • linux linux kernel (>= 5.11 < 5.15.166) • linux linux kernel (>= 5.16 < 6.1.107) • linux linux kernel (>= 6.2 < 6.6.48) • linux linux kernel (>= 6.7 < 6.10.7) • linux linux kernel 6.11
