[Xen-devel] [xen-unstable test] 112608: regressions - trouble: blocked/broken/fail/pass

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-armhf-pvops             6 kernel-build             fail REGR. vs. 112544

Tests which are failing intermittently (not blocking):
 test-amd64-amd64-xl-qemuu-win7-amd64 17 guest-stop fail in 112600 pass in 
112608
 test-amd64-amd64-qemuu-nested-intel 19 leak-check/check/l1 fail in 112600 pass 
in 112608
 test-amd64-i386-xl-qemuu-win7-amd64 16 guest-localmigrate/x10 fail pass in 
112600

Regressions which are regarded as allowable (not blocking):
 test-armhf-armhf-xl-rtds 16 guest-start/debian.repeat fail in 112600 REGR. vs. 
112544

    common/domain_page: Drop domain_mmap_cache infrastructure
    
    This infrastructure is used exclusively by the x86 do_mmu_update() 
hypercall.
    Mapping and unmapping domain pages is probably not the slow part of that
    function, but even with an opencoded caching implementation, Bloat-o-meter
    reports:

    The !CONFIG_DOMAIN_PAGE stub code has a mismatch between mapping and
    unmapping, which is a latent bug.

    The check is useless because pointer arithmetic ensures "info" is

    Replace it with an ASSERT for socket_info. The only caller of

    cpufreq: only stop ondemand governor if already started
    
    On CPUFREQ_GOV_STOP in cpufreq_governor_dbs, shortcut to
    return success if the governor is already stopped.
    
    Avoid executing dbs_timer_exit, to prevent tripping an assertion
    within a call to kill_timer on a timer that has not been prepared
    with init_timer, if the CPUFREQ_GOV_START case has not
    run beforehand.
    
    kill_timer validates timer state:
     * itself, via BUG_ON(this_cpu(timers).running == timer);
     * within active_timer, ASSERTing timer->status is within bounds;
     * within list_del, which ASSERTs timer inactive list membership.

    xsm: correct AVC lookups for two sysctls
    
    The current code was incorrectly using SECCLASS_XEN instead of
    SECCLASS_XEN2, resulting in the wrong permission being checked.
    
    GET_CPU_LEVELLING_CAPS was checking MTRR_DEL
    GET_CPU_FEATURESET was checking MTRR_READ
    
    The default XSM policy only allowed these permissions to dom0, so this
    didn't result in a security issue there.

    x86/tboot: disable interrupts after map_pages_to_xen() in tboot_shutdown()
    
    Move the point where interrupts are disabled in tboot_shutdown
    to slightly later, to after the call to map_pages_to_xen.
    
    This patch originated in OpenXT with the following report:
    
    "Disabling interrupts early causes debug assertions.
    
    This is only seen with debug builds but since it causes assertions it is
    probably a bigger problem. It clearly says in map_pages_to_xen that it
    should not be called with interrupts disabled. Moved disabling to just
    after that call."
    
    The Xen code comment ahead of map_pages_to_xen notes that the CPU cache
    flushing in map_pages_to_xen differs depending on whether interrupts are
    enabled or not. The flush logic with interrupts enabled is more
    conservative, flushing all CPUs' TLBs/caches, rather than just local.
    This is just before the tboot memory integrity MAC calculation is performed
    in the case of entering S3.

    x86/cpufeatures: expose UMIP to HVM guests
    
    User-Mode Instruction Prevention (UMIP) is a security feature present in
    new Intel Processors. With this feature, when the UMIP bit in CR4 set,
    the following instructions cannot be executed if CPL > 0: SGDT, SIDT,
    SLDT, SMSW, and STR. An attempt at such execution causes a general-
    protection exception (#GP).
    
    This patch simply adds necessary definitions to expose this feature to
    hvm guests.

    VT-d PI: disable VT-d PI when CPU-side PI isn't enabled
    
    From the context calling pi_desc_init(), we can conclude the current
    implementation of VT-d PI depends on CPU-side PI. If we enable VT-d PI
    and disable CPU-side PI by disabling APICv explicitly in xen boot
    command line, we would get an assertion failure.
    
    This patch clears iommu_intpost once finding CPU-side PI won't be enabled.
    It is safe for this is done before this flag starts taking effect. Also
    take this chance to remove the useless check of "acknowledge interrupt on
    exit", which is a minimal requirement which has been checked earlier.
