Subject: [for-4.15][PATCH v3 0/3] xen/iommu: Collection of bug fixes for IOMMU teadorwn
Date: Wed, 17 Feb 2021 14:24:55 +0000 [thread overview]
Message-ID: <20210217142458.3769-1-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.
Major changes since v2:
- patch #1 "xen/x86: p2m: Don't map the special pages in the IOMMU
page-tables" has been removed. This requires Jan's patch [2] to
fully mitigate memory leaks.
Cheers,
