commit 47d3e739e0a1daf94b102b027fa3425cbdff2e60
Author: George Dunlap <george.dunlap@xxxxxxxxxx>
Date:   Tue Nov 28 13:49:22 2017 +0100

    p2m: Check return value of p2m_set_entry() when decreasing reservation
    If the entire range specified to p2m_pod_decrease_reservation() is marked
    populate-on-demand, then it will make a single p2m_set_entry() call,
    reducing its PoD entry count.
    Unfortunately, in the right circumstances, this p2m_set_entry() call
    may fail.  It that case, repeated calls to decrease_reservation() may
    cause p2m->pod.entry_count to fall below zero, potentially tripping
    over BUG_ON()s to the contrary.
    Instead, check to see if the entry succeeded, and return false if not.
    The caller will then call guest_remove_page() on the gfns, which will
    return -EINVAL upon finding no valid memory there to return.
    Unfortunately if the order > 0, the entry may have partially changed.
    A domain_crash() is probably the safest thing in that case.
    Other p2m_set_entry() calls in the same function should be fine,
    because they are writing the entry at its current order.  Nonetheless,

    p2m: Always check to see if removing a p2m entry actually worked
    The PoD zero-check functions speculatively remove memory from the p2m,
    then check to see if it's completely zeroed, before putting it in the
    Unfortunately, the p2m_set_entry() calls may fail if the underlying
    pagetable structure needs to change and the domain has exhausted its
    p2m memory pool: for instance, if we're removing a 2MiB region out of
    a 1GiB entry (in the p2m_pod_zero_check_superpage() case), or a 4k
    region out of a 2MiB or larger entry (in the p2m_pod_zero_check()
    case); and the return value is not checked.
    The underlying mfn will then be added into the PoD cache, and at some
    point mapped into another location in the p2m.  If the guest
    afterwards ballons out this memory, it will be freed to the hypervisor
    and potentially reused by another domain, in spite of the fact that
    the original domain still has writable mappings to it.
    There are several places where p2m_set_entry() shouldn't be able to
    fail, as it is guaranteed to write an entry of the same order that
    succeeded before.  Add a backstop of crashing the domain just in case,
    and an ASSERT_UNREACHABLE() to flag up the broken assumption on debug
    While we're here, use PAGE_ORDER_2M rather than a magic constant.

    x86/pod: prevent infinite loop when shattering large pages
    When populating pages, the PoD may need to split large ones using
    p2m_set_entry and request the caller to retry (see ept_get_entry for
    p2m_set_entry may fail to shatter if it is not possible to allocate
    memory for the new page table. However, the error is not propagated
    resulting to the callers to retry infinitely the PoD.
    Prevent the infinite loop by return false when it is not possible to
    shatter the large mapping.
    This is XSA-246.
