Subject: [for-4.15][PATCH v2 0/5] xen/iommu: Collection of bug fixes for IOMMU teadorwn
Date: Tue,  9 Feb 2021 15:28:11 +0000	[thread overview]
Message-ID: <20210209152816.15792-1-julien@xen.org> (raw)

From: Julien Grall <jgrall@amazon.com>

Hi all,

This series is a collection of bug fixes for the IOMMU teardown code.
All of them are candidate for 4.15 as they can either leak memory or
lead to host crash/host corruption.

This is sent directly on xen-devel because all the issues were either
introduced in 4.15 or happen in the domain creation code.

Cheers,

Julien Grall (5):
  xen/x86: p2m: Don't map the special pages in the IOMMU page-tables
  xen/iommu: Check if the IOMMU was initialized before tearing down
  xen/iommu: iommu_map: Don't crash the domain if it is dying
  xen/iommu: x86: Don't leak the IOMMU page-tables
  xen/iommu: x86: Clear the root page-table before freeing the
    page-tables
