vfio/pds: Fix missing detach_ioas op
Résumé
vfio/pds: Fix missing detach_ioas op
Description d'origine
La description telle que publiée par la source (souvent en anglais).
In the Linux kernel, the following vulnerability has been resolved:
vfio/pds: Fix missing detach_ioas op
When CONFIG_IOMMUFD is enabled and a device is bound to the pds_vfio_pci
driver, the following WARN_ON() trace is seen and probe fails:
WARNING: CPU: 0 PID: 5040 at drivers/vfio/vfio_main.c:317 __vfio_register_dev+0x130/0x140 [vfio]
<...>
pds_vfio_pci 0000:08:00.1: probe with driver pds_vfio_pci failed with error -22
This is because the driver's vfio_device_ops.detach_ioas isn't set.
Fix this by using the generic vfio_iommufd_physical_detach_ioas
function.
