Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dpaa2-switch: fix handling of NAPI on the remove path<br /> <br /> All the NAPI instances for a DPSW device are attached to the first<br /> switch port&amp;#39;s net_device but shared by all ports. The NAPI instances get<br /> disabled only once the last port goes down.<br /> <br /> This causes an issue on the .remove() path where each port is<br /> unregistered and freed one at a time, causing the NAPI instances to be<br /> deleted even though they are not disabled.<br /> <br /> In order to avoid this, split up the unregister_netdev() calls from the<br /> free_netdev() so that we make sure all ports go down before we attempt<br /> a deletion of NAPI instances. Also, make the netif_napi_del() explicit<br /> as it is on the .probe() path.
