[Xen-devel] [xen-4.7-testing test] 130773: regressions - trouble: blocked/broken/fail/pass

flight 130773 xen-4.7-testing real [real]

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-arm64-pvops               <job status>                 broken
 build-arm64-xsm                 <job status>                 broken
 build-arm64                     <job status>                 broken
 test-xtf-amd64-amd64-5 50 xtf/test-hvm64-lbr-tsx-vmentry fail REGR. vs. 129540

Regressions which are regarded as allowable (not blocking):
 build-arm64-pvops             2 hosts-allocate         broken REGR. vs. 129540
 build-arm64                   2 hosts-allocate         broken REGR. vs. 129540
 build-arm64-xsm               2 hosts-allocate         broken REGR. vs. 129540

    VMX: allow migration of guests with SSBD enabled
    The backport of cd53023df9 ("x86/msr: Virtualise MSR_SPEC_CTRL.SSBD for
    guests to use") did not mirror the PV side change into the HVM (VMX-
    specific) code path.

    x86/shadow: shrink struct page_info's shadow_flags to 16 bits
    This is to avoid it overlapping the linear_pt_count field needed for PV
    domains. Introduce a separate, HVM-only pagetable_dying field to replace
    the sole one left in the upper 16 bits.
    Note that the accesses to ->shadow_flags in shadow_{pro,de}mote() get
    switched to non-atomic, non-bitops operations, as {test,set,clear}_bit()
    are not allowed on uint16_t fields and hence their use would have
    required ugly casts. This is fine because all updates of the field ought
    to occur with the paging lock held, and other updates of it use |= and
    &= as well (i.e. using atomic operations here didn't really guard
    against potentially racing updates elsewhere).
    This is part of XSA-280.

    x86/shadow: move OOS flag bit positions
    In preparation of reducing struct page_info's shadow_flags field to 16
    bits, lower the bit positions used for SHF_out_of_sync and
    Instead of also adjusting the open coded use in _get_page_type(),
    introduce shadow_prepare_page_type_change() to contain knowledge of the
    bit positions to shadow code.

    x86/mm: Don't perform flush after failing to update a guests L1e
    If the L1e update hasn't occured, the flush cannot do anything useful.  This
    skips the potentially expensive vcpumask_to_pcpumask() conversion, and
    broadcast TLB shootdown.
    More importantly however, we might be in the error path due to a bad va
    parameter from the guest, and this should not propagate into the TLB 
    logic.  The INVPCID instruction for example raises #GP for a non-canonical
    This is XSA-279.

    AMD/IOMMU: suppress PTE merging after initial table creation
    The logic is not fit for this purpose, so simply disable its use until
    it can be fixed / replaced. Note that this re-enables merging for the
    table creation case, which was disabled as a (perhaps unintended) side
    effect of the earlier "amd/iommu: fix flush checks". It relies on no
    page getting mapped more than once (with different properties) in this
    process, as that would still be beyond what the merging logic can cope
    with. But arch_iommu_populate_page_table() guarantees this afaict.
    This is part of XSA-275.

    amd/iommu: fix flush checks
    Flush checking for AMD IOMMU didn't check whether the previous entry
    was present, or whether the flags (writable/readable) changed in order
    to decide whether a flush should be executed.
    Fix this by taking the writable/readable/next-level fields into account,
    together with the present bit.
    Along these lines the flushing in amd_iommu_map_page() must not be
    omitted for PV domains. The comment there was simply wrong: Mappings may
    very well change, both their addresses and their permissions. Ultimately
    this should honor iommu_dont_flush_iotlb, but to achieve this
    amd_iommu_ops first needs to gain an .iotlb_flush hook.
    Also make clear_iommu_pte_present() static, to demonstrate there's no
    caller omitting the (subsequent) flush.
    This is part of XSA-275.
