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.
