Descriptions

In the Linux kernel, the following vulnerability has been resolved:

hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume

When the optional PRE_COPY support was added to speed up the device
compatibility check, it failed to update the saving/resuming data
pointers based on the fd offset. This results in migration data
corruption and when the device gets started on the destination the
following error is reported in some cases,

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: hisi_acc_vfio_pci: actualiza correctamente el puntero de datos de migración al guardar/reanudar Cuando se agregó el soporte PRE_COPY opcional para acelerar la verificación de compatibilidad del dispositivo, no se pudieron actualizar los punteros de datos de guardado/reanudación según el desplazamiento fd. Esto da como resultado la corrupción de los datos de migración y cuando el dispositivo se inicia en el destino, en algunos casos se informa el siguiente error, [ 478.907684] arm-smmu-v3 arm-smmu-v3.2.auto: event 0x10 received: [ 478.913691] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000310200000010 [ 478.919603] arm-smmu-v3 arm-smmu-v3.2.auto: 0x000002088000007f [ 478.925515] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.931425] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.947552] hisi_zip 0000:31:00.0: qm_axi_rresp [error status=0x1] found [ 478.955930] hisi_zip 0000:31:00.0: qm_db_timeout [error status=0x400] found [ 478.955944] hisi_zip 0000:31:00.0: qm sq doorbell timeout in function 2
