Summary
iommufd: Make sure to zero vfio_iommu_type1_info before copying to user
Details

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

iommufd: Make sure to zero vfioiommutype1_info before copying to user

Missed a zero initialization here. Most of the struct is filled with a copyfromuser(), however minsz for that copy is smaller than the actual struct by 8 bytes, thus we don't fill the padding.
