Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-xl-qcow2     3 host-install(3)         broken REGR. vs. 78924
 test-amd64-i386-freebsd10-amd64  3 host-install(3)      broken REGR. vs. 78924
 test-armhf-armhf-xl-arndale   7 host-ping-check-xen       fail REGR. vs. 78924
 test-amd64-amd64-xl-qemuu-win7-amd64 15 guest-localmigrate/x10 fail REGR. vs.

Regressions which are regarded as allowable (not blocking):
 test-amd64-i386-xl-qemuu-win7-amd64 16 guest-stop              fail like 78789

    x86/VMX: sanitize rIP before re-entering guest

    ... to prevent guest user mode arranging for a guest crash (due to
    failed VM entry). (On the AMD system I checked, hardware is doing
    exactly the canonicalization being added here.)

    Note that fixing this in an architecturally correct way would be quite
    a bit more involved: Making the x86 instruction emulator check all
    branch targets for validity, plus dealing with invalid rIP resulting
    from update_guest_eip() or incoming directly during a VM exit. The only
    way to get the latter right would be by not having hardware do the
    injection.

    Note further that there are a two early returns from
    vmx_vmexit_handler(): One (through vmx_failed_vmentry()) leads to
    domain_crash() anyway, and the other covers real mode only and can
    neither occur with a non-canonical rIP nor result in an altered rIP,
    so we don't need to force those paths through the checking logic.

    This is CVE-2016-2271 / XSA-170.

    x86: enforce consistent cachability of MMIO mappings

    We've been told by Intel that inconsistent cachability between
    multiple mappings of the same page can affect system stability only
    when the affected page is an MMIO one. Since the stale data issue is
    of no relevance to the hypervisor (since all guest memory accesses go
    through proper accessors and validation), handling of RAM pages
    remains unchanged here. Any MMIO mapped by domains however needs to be
    done consistently (all cachable mappings or all uncachable ones), in
    order to avoid Machine Check exceptions. Since converting existing
    cachable mappings to uncachable (at the time an uncachable mapping
    gets established) would in the PV case require tracking all mappings,
    allow MMIO to only get mapped uncachable (UC, UC-, or WC).

    This also implies that in the PV case we mustn't use the L1 PTE update
    fast path when cachability flags get altered.

    Since in the HVM case at least for now we want to continue honoring
    pinned cachability attributes for pages not mapped by the hypervisor,
    special case handling of r/o MMIO pages (forcing UC) gets added there.
    Arguably the counterpart change to p2m-pt.c may not be necessary, since
    UC- (which already gets enforced there) is probably strict enough.

    Note that the shadow code changes include fixing the write protection
    of r/o MMIO ranges: shadow_l1e_remove_flags() and its siblings, other
    than l1e_remove_flags() and alike, return the new PTE (and hence
    ignoring their return values makes them no-ops).

    This is CVE-2016-2270 / XSA-154.
