Since a wiphy work can only run under wiphy lock\nprotection, a race condition happens in below scenario:\n\n1. a management frame is queued for transmission.\n2. ath12k_mac_op_flush() gets called to flush pending frames associated\n with the hardware (i.e, vif being NULL). Then in ath12k_mac_flush()\n the process waits for the transmission done.\n3. Since wiphy lock has been taken by the flush process, the transmission\n work item has no chance to run, hence the dead lock.\n\n>From user view, this dead lock results in below issue:\n\n wlp8s0: authenticate with xxxxxx (local address=xxxxxx)\n wlp8s0: send auth to xxxxxx (try 1/3)\n wlp8s0: authenticate with xxxxxx (local address=xxxxxx)\n wlp8s0: send auth to xxxxxx (try 1/3)\n wlp8s0: authenticated\n wlp8s0: associate with xxxxxx (try 1/3)\n wlp8s0: aborting association with xxxxxx by local choice (Reason: 3=DEAUTH_LEAVING)\n ath12k_pci 0000:08:00.0: failed to flush mgmt transmit queue, mgmt pkts pending 1\n\nThe dead lock can be avoided by invoking wiphy_work_flush() to proactively\nrun the queued work item. Note actually it is already present in\nath12k_mac_op_flush(), however it does not protect the case where vif\nbeing NULL. Hence move it ahead to cover this case as well.\n\nTested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3"}, {"lang": "es", "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:\n\nwifi: ath12k: solucionar interbloqueo al vaciar tramas de gesti\u00f3n\n\nEl commit [1] convirti\u00f3 el elemento de trabajo de transmisi\u00f3n de gesti\u00f3n en un trabajo wiphy. Dado que un trabajo wiphy solo puede ejecutarse bajo la protecci\u00f3n del bloqueo wiphy, ocurre una condici\u00f3n de carrera en el siguiente escenario:\n\n1. una trama de gesti\u00f3n se pone en cola para transmisi\u00f3n.\n2. se llama a ath12k_mac_op_flush() para vaciar las tramas pendientes asociadas con el hardware (es decir, vif es NULL). Luego, en ath12k_mac_flush(), el proceso espera a que la transmisi\u00f3n finalice.\n3. Dado que el bloqueo wiphy ha sido tomado por el proceso de vaciado, el elemento de trabajo de transmisi\u00f3n no tiene oportunidad de ejecutarse, de ah\u00ed el interbloqueo.\n\nDesde la perspectiva del usuario, este interbloqueo resulta en el siguiente problema:\n\n wlp8s0: autenticar con xxxxxx (direcci\u00f3n local=xxxxxx)\n wlp8s0: enviar autenticaci\u00f3n a xxxxxx (intento 1/3)\n wlp8s0: autenticar con xxxxxx (direcci\u00f3n local=xxxxxx)\n wlp8s0: enviar autenticaci\u00f3n a xxxxxx (intento 1/3)\n wlp8s0: autenticado\n wlp8s0: asociar con xxxxxx (intento 1/3)\n wlp8s0: abortando asociaci\u00f3n con xxxxxx por elecci\u00f3n local (Raz\u00f3n: 3=DEAUTH_LEAVING)\n ath12k_pci 0000:08:00.0: fall\u00f3 al vaciar la cola de transmisi\u00f3n de gesti\u00f3n, paquetes de gesti\u00f3n pendientes 1\n\nEl interbloqueo puede evitarse invocando wiphy_work_flush() para ejecutar proactivamente el elemento de trabajo en cola.
