n the Linux kernel, the following vulnerability has been resolved: page_pool: avoid infinite loop to schedule delayed worker We noticed the kworker in page_pool_release_retry() was waken up repeatedly and infinitely in production because of the buggy driver causing the inflight less than 0 and warning us in page_pool_inflight()[1]. Since the inflight value goes negative, it means we should not expect the whole page_pool to get back to work normally. This patch mitigates the adverse effect by not rescheduling the kworker when detecting the inflight negative in page_pool_release_retry().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: page_pool: evitar bucle infinito para programar un trabajador retrasado. Observamos que el kworker en page_pool_release_retry() se reactivaba repetida e infinitamente en producción debido a un controlador defectuoso que causaba un valor inflight menor que 0 y nos advertía en page_pool_inflight()[1]. Dado que el valor inflight es negativo, no debemos esperar que todo el page_pool vuelva a funcionar con normalidad. Este parche mitiga el efecto adverso al no reprogramar el kworker al detectar un valor inflight negativo en page_pool_release_retry().
