Title
idpf: fix UAFs when destroying the queues
Summary
In the Linux kernel, the following vulnerability has been resolved: idpf: fix UAFs when destroying the queues The second tagged commit started sometimes (very rarely, but possible) throwing WARNs from net/core/page_pool.c:page_pool_disable_direct_recycling(). Turned out idpf frees interrupt vectors with embedded NAPIs *before* freeing the queues making page_pools' NAPI pointers lead to freed memory before these pools are destroyed by libeth. It's not clear whether there are other accesses to the freed vectors when destroying the queues, but anyway, we usually free queue/interrupt vectors only when the queues are destroyed and the NAPIs are guaranteed to not be referenced anywhere. Invert the allocation and freeing logic making queue/interrupt vectors be allocated first and freed last. Vectors don't require queues to be present, so this is safe. Additionally, this change allows to remove that useless queue->q_vector pointer cleanup, as vectors are still valid when freeing the queues (+ both are freed within one function, so it's not clear why nullify the pointers at all).

Result\u00f3 que idpf libera los vectores de interrupci\u00f3n con NAPI incorporadas *antes* de liberar las colas, lo que hace que los punteros NAPI de page_pools conduzcan a la memoria liberada antes de que Libeth destruya estos grupos. No est\u00e1 claro si hay otros accesos a los vectores liberados al destruir las colas, pero de todos modos, generalmente liberamos vectores de cola/interrupci\u00f3n solo cuando las colas se destruyen y se garantiza que no se har\u00e1 referencia a las NAPI en ninguna parte. Invierta la l\u00f3gica de asignaci\u00f3n y liberaci\u00f3n haciendo que los vectores de cola/interrupci\u00f3n se asignen primero y se liberen al final. Los vectores no requieren la presencia de colas, por lo que esto es seguro.

Result\u00f3 que idpf libera los vectores de interrupci\u00f3n con NAPI incorporadas *antes* de liberar las colas, lo que hace que los punteros NAPI de page_pools conduzcan a la memoria liberada antes de que Libeth destruya estos grupos. No est\u00e1 claro si hay otros accesos a los vectores liberados al destruir las colas, pero de todos modos, generalmente liberamos vectores de cola/interrupci\u00f3n solo cuando las colas se destruyen y se garantiza que no se har\u00e1 referencia a las NAPI en ninguna parte. Invierta la l\u00f3gica de asignaci\u00f3n y liberaci\u00f3n haciendo que los vectores de cola/interrupci\u00f3n se asignen primero y se liberen al final.

Vectors don\u0027t require queues to be\npresent, so this is safe. Additionally, this change allows to remove\nthat useless queue-\u003eq_vector pointer cleanup, as vectors are still\nvalid when freeing the queues (+ both are freed within one function,\nso it\u0027s not clear why nullify the pointers at all)."
