[Xen-devel] [xen-4.6-testing test] 66421: regressions - trouble: broken/fail/pass

flight 66421 xen-4.6-testing real [real]

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-xl-qemut-stubdom-debianhvm-amd64-xsm 13 guest-localmigrate 
fail REGR. vs. 65639

Tests which are failing intermittently (not blocking):
 test-armhf-armhf-libvirt-qcow2  3 host-install(3)         broken pass in 66394

Regressions which are regarded as allowable (not blocking):

    VT-d: drop unneeded Ivybridge quirk workaround
    We've been told by Intel that server chipsets don't need the workaround
    anymore starting with Ivybridge (Xeon E5/E7 v2); the second half of the
    workaround was missing anyway.

    evtchn: don't reuse ports that are still "busy"
    When using the FIFO ABI a guest may close an event channel that is
    still LINKED.  If this port is reused, subsequent events may be lost
    because they may become pending on the wrong queue.
    This could be fixed by requiring guests to only close event channels
    that are not linked.  This is difficult since: a) irq cleanup in the
    guest may be done in a context that cannot wait for the event to be
    unlinked; b) the guest may attempt to rebind a PIRQ whose previous
    close is still pending; and c) existing guests already have the
    problematic behaviour.
    Instead, simply check a port is not "busy" (i.e., it's not linked)
    before reusing it.
    Guests should still drain any queues for VCPUs that are being
    offlined, or the port will become unusable until the VCPU is onlined
    and starts processing events again.

    x86/ept: remove unnecessary sync after resolving misconfigured entries
    When using EPT, type changes are done with the following steps:
    1. Set entry as invalid (misconfigured) by settings a reserved memory
    2. Flush all EPT and combined translations (ept_sync_domain()).
    3. Fixup misconfigured entries as required (on EPT_MISCONFIG vmexits or
    when explicitly setting an entry.
    Since resolve_misconfig() only updates entries that were misconfigured,
    there is no need to invalidate any translations since the hardware
    does not cache misconfigured translations (vol 3, section 28.3.2).
    Remove the unnecessary (and very expensive) ept_sync_domain() calls).

    x86/boot: check for not allowed sections before linking
    Currently check for not allowed sections is performed just after
    compilation. However, if compilation succeeds and check fails then
    second build will create xen.gz/xen.efi without any visible error.
    This happens because %.o: %.c recipe created object file during first
    run and make do not execute this recipe during second run. So, look
    for not allowed sections before linking. This way check will be
    executed every time.

    x86/VPMU: Initialize VPMU's lvtpc vector
    If a guest sets up performance counters so that they can generate
    a PMC interrupt but does not initilaize APIC LVTPC register the
    resulting interrupt will cause an APIC error.
    Note that a guest deciding to clear LVTPC in order to unduce the error
    will not be successful in achieving its goal: emulation code only
    looks at the mask bit and always sets the vector to PMU_APIC_VECTOR.
    Only the initial value of LVTPC (which is zero) that gets loaded into
    APIC as result of PMC initialization is the problem.

    sched: fix locking for insert_vcpu() in credit1 and RTDS
    The insert_vcpu() hook is handled with inconsistent locking.
    In fact, schedule_cpu_switch() calls the hook with runqueue
    lock held, while sched_move_domain() relies on the hook
    implementations to take the lock themselves (and, since that
    is not done in Credit1 and RTDS, such operation is not safe
    in those cases).
    This is fixed as follows:
     - take the lock in the hook implementations, in specific
       schedulers' code;
     - avoid calling insert_vcpu(), for the idle vCPU, in
       schedule_cpu_switch(). In fact, idle vCPUs are set to run
       immediately, and the various schedulers won't insert them
       in their runqueues anyway, even when explicitly asked to.
    While there, still in schedule_cpu_switch(), locking with
    _irq() is enough (there's no need to do *_irqsave()).

    VMX: fix/adjust trap injection
    In the course of investigating the 4.1.6 backport issue of the XSA-156
    patch I realized that #DB injection has always been broken, but with it
    now getting always intercepted the problem has got worse: Documentation
    clearly states that neither DR7.GD nor DebugCtl.LBR get cleared before
    the intercept, so this is something we need to do before reflecting the
    intercepted exception.
    While adjusting this (and also with 4.1.6's strange use of
    X86_EVENTTYPE_SW_EXCEPTION for #DB in mind) I further realized that
    the special casing of individual vectors shouldn't be done for
    software interrupts (resulting from INT $nn).
    And then some code movement: Setting of CR2 for #PF can be done in the
    same switch() statement (no need for a separate if()), and reading of
    intr_info is better done close the the consumption of the variable
    (allowing the compiler to generate better code / use fewer registers
    for variables).
