Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:

    x86/P2M: deal with partial success of p2m_set_entry()
    
    M2P and PoD stats need to remain in sync with P2M; if an update succeeds
    only partially, respective adjustments need to be made. If updates get
    made before the call, they may also need undoing upon complete failure
    (i.e. including the single-page case).
    
    Log-dirty state would better also be kept in sync.
    
    Note that the change to set_typed_p2m_entry() may not be strictly
    necessary (due to the order restriction enforced near the top of the
    function), but is being kept here to be on the safe side.
    
    This is CVE-2021-28705 and CVE-2021-28709 / XSA-389.

    x86/PoD: handle intermediate page orders in p2m_pod_cache_add()
    
    p2m_pod_decrease_reservation() may pass pages to the function which
    aren't 4k, 2M, or 1G. Handle all intermediate orders as well, to avoid
    hitting the BUG() at the switch() statement's "default" case.
    
    This is CVE-2021-28708 / part of XSA-388.

    x86/PoD: deal with misaligned GFNs
    
    Users of XENMEM_decrease_reservation and XENMEM_populate_physmap aren't
    required to pass in order-aligned GFN values. (While I consider this
    bogus, I don't think we can fix this there, as that might break existing
    code, e.g Linux'es swiotlb, which - while affecting PV only - until
    recently had been enforcing only page alignment on the original
    allocation.) Only non-PoD code paths (guest_physmap_{add,remove}_page(),
    p2m_set_entry()) look to be dealing with this properly (in part by being
    implemented inefficiently, handling every 4k page separately).
    
    Introduce wrappers taking care of splitting the incoming request into
    aligned chunks, without putting much effort in trying to determine the
    largest possible chunk at every iteration.
    
    Also "handle" p2m_set_entry() failure for non-order-0 requests by
    crashing the domain in one more place. Alongside putting a log message
    there, also add one to the other similar path.
    
    Note regarding locking: This is left in the actual worker functions on
    the assumption that callers aren't guaranteed atomicity wrt acting on
    multiple pages at a time. For mis-aligned GFNs gfn_lock() wouldn't have
    locked the correct GFN range anyway, if it didn't simply resolve to
    p2m_lock(), and for well-behaved callers there continues to be only a
    single iteration, i.e. behavior is unchanged for them. (FTAOD pulling
    out just pod_lock() into p2m_pod_decrease_reservation() would result in
    a lock order violation.)
    
    This is CVE-2021-28704 and CVE-2021-28707 / part of XSA-388.

    xen/page_alloc: Harden assign_pages()
    
    domain_tot_pages() and d->max_pages are 32-bit values. While the order
    should always be quite small, it would still be possible to overflow
    if domain_tot_pages() is near to (2^32 - 1).
    
    As this code may be called by a guest via XENMEM_increase_reservation
    and XENMEM_populate_physmap, we want to make sure the guest is not going
    to be able to allocate more than it is allowed.
    
    Rework the allocation check to avoid any possible overflow. While the
    check domain_tot_pages() < d->max_pages should technically not be
    necessary, it is probably best to have it to catch any possible
    inconsistencies in the future.
    
    This is CVE-2021-28706 / part of XSA-385.
