Subject: [PATCH v3 07/14] xen: Introduce HAS_M2P config and use to protect mfn_to_gmfn call
Date: Mon,  3 Jun 2019 17:03:43 +0100	[thread overview]
Message-ID: <20190603160350.29806-8-julien.grall@arm.com> (raw)
In-Reply-To: <20190603160350.29806-1-julien.grall@arm.com>

While Arm never had a M2P, the implementation of mfn_to_gmfn is pretty
bogus as we directly return the MFN passed in parameter.

Thankfully, the use of mfn_to_gmfn is pretty limited on Arm today. There
are only 3 callers:
    - iommu_hwdom_init: mfn_to_gmfn is used for creating IOMMU
    page-tables when the P2M is not shared with the IOMMU. No issues so
    far as Arm does not yet support non-shared P2M case.
    - memory_exchange: Arm cannot not use it because steal_page is not
    implemented.
    - getdomaininfo: Toolstack may map the shared page. It looks like
    this is mostly used for mapping the P2M of PV guest. Therefore the
    issue might be minor.

Implementing the M2P on Arm is not planned. The M2P would require significant
amount of VA address (very tough on 32-bit) that can hardly be justified with
the current use of mfn_to_gmfn.
    - iommu_hwdom_init: mfn_to_gmfn is used because the creating of the
    IOMMU page-tables is delayed until the first device is assigned.
    In the embedded case, we will known in most of the times what
    devices are assigned during the domain creation. So it is possible
    to take to enable the IOMMU from start. See [1] for the patch.
    - memory_exchange: This does not work and I haven't seen any
    request for it so far.
    - getdomaininfo: The structure on Arm does not seem to contain a lot
    of useful information on Arm. It is unclear whether we want to
    allow the toolstack mapping it on Arm.

This patch introduces a config option HAS_M2P to tell whether an
architecture implements the M2P.
    - iommu_hwdom_init: For now, we require the M2P support when the IOMMU
    is not sharing the P2M.
    - memory_exchange: The hypercall is marked as not supported when the
    M2P does not exist.
    - getdomaininfo: A new helper is introduced to wrap the call to
    mfn_to_gfn/mfn_to_gmfn. For Arm, a fixed value will be provided that will
    fail on mapping if used.

    Changes in v3:
        - Move the BUG_ON() in domain_shared_info_gfn()
        - Use a fixed value when the field shared_info_frame is not
        supported.
        - Add an ASSERT_UNREACHABLE in iommu_hwdom_init + move printk
        within the #ifdef.

    Changes in v2:
        - Add a warning in public headers
        - Constify local variable in domain_shared_info_gfn
        - Invert the naming (_d / d) in domain_shared_info_gfn
        - Use -EOPNOTSUPP rather than -ENOSYS
        - Rework how the memory_exchange hypercall is removed from Arm
