706a63e840 vfio/pci: Move dummy_resources_list init in vfio_pci_probe()
[ Upstream commit 16b8fe4caf ]

In case an error occurs in vfio_pci_enable() before the call to
vfio_pci_probe_mmaps(), vfio_pci_disable() will  try to iterate
on an uninitialized list and cause a kernel panic.

Lets move to the initialization to vfio_pci_probe() to fix the
issue.

bb3130192f vfio-pci: Use io_remap_pfn_range() for PCI IO memory
[ Upstream commit 7b06a56d46 ]

commit f8f6ae5d07 ("mm: always have io_remap_pfn_range() set
pgprot_decrypted()") allows drivers using mmap to put PCI memory mapped
BAR space into userspace to work correctly on AMD SME systems that default
to all memory encrypted.

Since vfio_pci_mmap_fault() is working with PCI memory mapped BAR space it
should be calling io_remap_pfn_range() otherwise it will not work on SME
systems.

707f8d0d38 vfio iommu type1: Fix memory leak in vfio_iommu_type1_pin_pages
[ Upstream commit 2e6cfd496f ]

pfn is not added to pfn_list when vfio_add_to_pfn_list fails.
vfio_unpin_page_external will exit directly without calling
vfio_iova_put_vfio_pfn.  This will lead to a memory leak.

f393f4a5fc vfio/pci: Clear token on bypass registration failure
[ Upstream commit 852b1beecb ]

The eventfd context is used as our irqbypass token, therefore if an
eventfd is re-used, our token is the same.  The irqbypass code will
return an -EBUSY in this case, but we'll still attempt to unregister
the producer, where if that duplicate token still exists, results in
removing the wrong object.  Clear the token of failed producers so
that they harmlessly fall out when unregistered.

0d1682ca6d vfio/pci: fix racy on error and request eventfd ctx
[ Upstream commit b872d06408 ]

The vfio_pci_release call will free and clear the error and request
eventfd ctx while these ctx could be in use at the same time in the
function like vfio_pci_request, and it's expected to protect them under
the vdev->igate mutex, which is missing in vfio_pci_release.

This issue is introduced since commit 1518ac272e ("vfio/pci: fix memory
leaks of eventfd ctx"),and since commit 5c5866c593 ("vfio/pci: Clear
error and request eventfd ctx after releasing"), it's very easily to
trigger the kernel panic like this:

b7e24664cc vfio/pci: fix memory leaks of eventfd ctx
[ Upstream commit 1518ac272e ]

Finished a qemu-kvm (-device vfio-pci,host=0001:01:00.0) triggers a few
memory leaks after a while because vfio_pci_set_ctx_trigger_single()
calls eventfd_ctx_fdget() without the matching eventfd_ctx_put() later.
Fix it by calling eventfd_ctx_put() for those memory in
vfio_pci_release() before vfio_device_release().

81fb345971 vfio/pci: Fix SR-IOV VF handling with MMIO blocking
commit ebfa440ce3 upstream.

SR-IOV VFs do not implement the memory enable bit of the command
register, therefore this bit is not set in config space after
pci_enable_device().  This leads to an unintended difference
between PF and VF in hand-off state to the user.  We can correct
this by setting the initial value of the memory enable bit in our
virtualized config space.  There's really no need however to
ever fault a user on a VF though as this would only indicate an
error in the user's management of the enable bit, versus a PF
where the same access could trigger hardware faults.

da7aea6eb5 vfio-pci: Invalidate mmaps and block MMIO access on disabled memory
commit abafbc551f upstream.

Accessing the disabled memory space of a PCI device would typically
result in a master abort response on conventional PCI, or an
unsupported request on PCI express.  The user would generally see
these as a -1 response for the read return data and the write would be
silently discarded, possibly with an uncorrected, non-fatal AER error
triggered on the host.  Some systems however take it upon themselves
to bring down the entire system when they see something that might
indicate a loss of data, such as this discarded write to a disabled
memory space.

To avoid this, we want to try to block the user from accessing memory
spaces while they're disabled.  We start with a semaphore around the
memory enable bit, where writers modify the memory enable state and
must be serialized, while readers make use of the memory region and
can access in parallel.  Writers include both direct manipulation via
the command register, as well as any reset path where the internal
mechanics of the reset may both explicitly and implicitly disable
memory access, and manipulation of the MSI-X configuration, where the
MSI-X vector table resides in MMIO space of the device.  Readers
include the read and write file ops to access the vfio device fd
offsets as well as memory mapped access.  In the latter case, we make
use of our new vma list support to zap, or invalidate, those memory
mappings in order to force them to be faulted back in on access.

Our semaphore usage will stall user access to MMIO spaces across
internal operations like reset, but the user might experience new
behavior when trying to access the MMIO space while disabled via the
PCI command register.  Access via read or write while disabled will
return -EIO and access via memory maps will result in a SIGBUS.  This
is expected to be compatible with known use cases and potentially
provides better error handling capabilities than present in the
hardware, while avoiding the more readily accessible and severe
platform error responses that might otherwise occur.

6c7f2f24a8 vfio-pci: Fault mmaps to enable vma tracking
commit 11c4cd07ba upstream.

Rather than calling remap_pfn_range() when a region is mmap'd, setup
a vm_ops handler to support dynamic faulting of the range on access.
This allows us to manage a list of vmas actively mapping the area that
we can later use to invalidate those mappings.  The open callback
invalidates the vma range so that all tracking is inserted in the
fault handler and removed in the close handler.

d200964e4d vfio/type1: Add proper error unwind for vfio_iommu_replay()
[ Upstream commit aae7a75a82 ]

The vfio_iommu_replay() function does not currently unwind on error,
yet it does pin pages, perform IOMMU mapping, and modify the vfio_dma
structure to indicate IOMMU mapping.  The IOMMU mappings are torn down
when the domain is destroyed, but the other actions go on to cause
trouble later.  For example, the iommu->domain_list can be empty if we
only have a non-IOMMU backed mdev attached.  We don't currently check
if the list is empty before getting the first entry in the list, which
leads to a bogus domain pointer.  If a vfio_dma entry is erroneously
marked as iommu_mapped, we'll attempt to use that bogus pointer to
retrieve the existing physical page addresses.

This is the scenario that uncovered this issue, attempting to hot-add
a vfio-pci device to a container with an existing mdev device and DMA
mappings, one of which could not be pinned, causing a failure adding
the new group to the existing container and setting the conditions
for a subsequent attempt to explode.

To resolve this, we can first check if the domain_list is empty so
that we can reject replay of a bogus domain, should we ever encounter
this inconsistent state again in the future.  The real fix though is
to add the necessary unwind support, which means cleaning up the
current pinning if an IOMMU mapping fails, then walking back through
the r-b tree of DMA entries, reading from the IOMMU which ranges are
mapped, and unmapping and unpinning those ranges.  To be able to do
this, we also defer marking the DMA entry as IOMMU mapped until all
entries are processed, in order to allow the unwind to know the
disposition of each entry.

1a98e4ef32 vfio/mdev: Fix reference count leak in add_mdev_supported_type
[ Upstream commit aa8ba13cae ]

kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Thus,
replace kfree() by kobject_put() to fix this issue. Previous
commit "b8eb718348b8" fixed a similar problem.

e9aaff2b5f vfio-pci: Mask cap zero
[ Upstream commit bc138db1b9 ]

The PCI Code and ID Assignment Specification changed capability ID 0
from reserved to a NULL capability in the v1.1 revision.  The NULL
capability is defined to include only the 16-bit capability header,
ie. only the ID and next pointer.  Unfortunately vfio-pci creates a
map of config space, where ID 0 is used to reserve the standard type
0 header.  Finding an actual capability with this ID therefore results
in a bogus range marked in that map and conflicts with subsequent
capabilities.  As this seems to be a dummy capability anyway and we
already support dropping capabilities, let's hide this one rather than
delving into the potentially subtle dependencies within our map.

Seen on an NVIDIA Tesla T4.

cf25855e9f vfio/type1: Fix VA->PA translation for PFNMAP VMAs in vaddr_get_pfn()
commit 5cbf3264bc upstream.

Use follow_pfn() to get the PFN of a PFNMAP VMA instead of assuming that
vma->vm_pgoff holds the base PFN of the VMA.  This fixes a bug where
attempting to do VFIO_IOMMU_MAP_DMA on an arbitrary PFNMAP'd region of
memory calculates garbage for the PFN.

Hilariously, this only got detected because the first "PFN" calculated
by vaddr_get_pfn() is PFN 0 (vma->vm_pgoff==0), and iommu_iova_to_phys()
uses PA==0 as an error, which triggers a WARN in vfio_unmap_unpin()
because the translation "failed".  PFN 0 is now unconditionally reserved
on x86 in order to mitigate L1TF, which causes is_invalid_reserved_pfn()
to return true and in turns results in vaddr_get_pfn() returning success
for PFN 0.  Eventually the bogus calculation runs into PFNs that aren't
reserved and leads to failure in vfio_pin_map_dma().  The subsequent
call to vfio_remove_dma() attempts to unmap PFN 0 and WARNs.

5babded444 vfio/mdev: Fix aborting mdev child device removal if one fails
[ Upstream commit 6093e348a5 ]

device_for_each_child() stops executing callback function for remaining
child devices, if callback hits an error.
Each child mdev device is independent of each other.
While unregistering parent device, mdev core must remove all child mdev
devices.
Therefore, mdev_device_remove_cb() always returns success so that
device_for_each_child doesn't abort if one child removal hits error.

While at it, improve remove and unregister functions for below simplicity.

There isn't need to pass forced flag pointer during mdev parent
removal which invokes mdev_device_remove(). So simplify the flow.

mdev_device_remove() is called from two paths.
1. mdev_unregister_driver()
     mdev_device_remove_cb()
       mdev_device_remove()
2. remove_store()
     mdev_device_remove()

Fixes: 7b96953bc6 ("vfio: Mediated device Core driver")

mdev_remove_sysfs_files() should follow exact mirror sequence of a
create, similar to what is followed in error unwinding path of
mdev_create_sysfs_files().

5c5492ee3e vfio/mdev: Avoid release parent reference during error path
[ Upstream commit 60e7f2c3fe ]

During mdev parent registration in mdev_register_device(),
if parent device is duplicate, it releases the reference of existing
parent device.
This is incorrect. Existing parent device should not be touched.

c8fa33f831 vfio_pci: Enable memory accesses before calling pci_map_rom
[ Upstream commit 0cfd027be1 ]

pci_map_rom/pci_get_rom_size() performs memory access in the ROM.
In case the Memory Space accesses were disabled, readw() is likely
to trigger a synchronous external abort on some platforms.

In case memory accesses were disabled, re-enable them before the
call and disable them back again just after.

Jiang Yi
73155507af vfio/pci: call irq_bypass_unregister_producer() before freeing irq
commit d567fb8819 upstream.

Since irq_bypass_register_producer() is called after request_irq(), we
should do tear-down in reverse order: irq_bypass_unregister_producer()
then free_irq().

Specifically free_irq() may release resources required by the
irqbypass del_producer() callback.  Notably an example provided by
Marc Zyngier on arm64 with GICv4 that he indicates has the potential
to wedge the hardware:

 free_irq(irq)
   __free_irq(irq)
     irq_domain_deactivate_irq(irq)
       its_irq_domain_deactivate()
         [unmap the VLPI from the ITS]

 kvm_arch_irq_bypass_del_producer(cons, prod)
   kvm_vgic_v4_unset_forwarding(kvm, irq, ...)
     its_unmap_vlpi(irq)
       [Unmap the VLPI from the ITS (again), remap the original LPI]

42cdd8e961 vfio/spapr_tce: Get rid of possible infinite loop
[ Upstream commit 517ad4ae8a ]

As a part of cleanup, the SPAPR TCE IOMMU subdriver releases preregistered
memory. If there is a bug in memory release, the loop in
tce_iommu_release() becomes infinite; this actually happened to me.

This makes the loop finite and prints a warning on every failure to make
the code more bug prone.

1ae5bfee6c vfio/pci: Mask buggy SR-IOV VF INTx support
[ Upstream commit db04264fe9 ]

The SR-IOV spec requires that VFs must report zero for the INTx pin
register as VFs are precluded from INTx support.  It's much easier for
the host kernel to understand whether a device is a VF and therefore
whether a non-zero pin register value is bogus than it is to do the
same in userspace.  Override the INTx count for such devices and
virtualize the pin register to provide a consistent view of the device
to the user.

As this is clearly a spec violation, warn about it to support hardware
validation, but also provide a known whitelist as it doesn't do much
good to continue complaining if the hardware vendor doesn't plan to
fix it.

Known devices with this issue: 8086:270c

46850ae936 UPSTREAM: vfio/type1: untag user pointers in vaddr_get_pfn
(Upstream commit 6cf5354c1c).

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

vaddr_get_pfn() uses provided user pointers for vma lookups, which can
only by done with untagged pointers.

Untag user pointers in this function.

9b2d2f2ad0 vfio_pci: Restore original state on release
[ Upstream commit 92c8026854 ]

vfio_pci_enable() saves the device's initial configuration information
with the intent that it is restored in vfio_pci_disable().  However,
the commit referenced in Fixes: below replaced the call to
__pci_reset_function_locked(), which is not wrapped in a state save
and restore, with pci_try_reset_function(), which overwrites the
restored device state with the current state before applying it to the
device.  Reinstate use of __pci_reset_function_locked() to return to
the desired behavior.

f7883f9b5a vfio: Fix WARNING "do not call blocking ops when !TASK_RUNNING"
[ Upstream commit 41be3e2618 ]

vfio_dev_present() which is the condition to
wait_event_interruptible_timeout(), will call vfio_group_get_device
and try to acquire the mutex group->device_lock.

wait_event_interruptible_timeout() will set the state of the current
task to TASK_INTERRUPTIBLE, before doing the condition check. This
means that we will try to acquire the mutex while already in a
sleeping state. The scheduler warns us by giving the following
warning:

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for unsigned ints.

f7b467ad1b vfio/type1: Limit DMA mappings per container
commit 492855939b upstream.

Memory backed DMA mappings are accounted against a user's locked
memory limit, including multiple mappings of the same memory.  This
accounting bounds the number of such mappings that a user can create.
However, DMA mappings that are not backed by memory, such as DMA
mappings of device MMIO via mmaps, do not make use of page pinning
and therefore do not count against the user's locked memory limit.
These mappings still consume memory, but the memory is not well
associated to the process for the purpose of oom killing a task.

To add bounding on this use case, we introduce a limit to the total
number of concurrent DMA mappings that a user is allowed to create.
This limit is exposed as a tunable module option where the default
value of 64K is expected to be well in excess of any reasonable use
case (a large virtual machine configuration would typically only make
use of tens of concurrent mappings).

This fixes CVE-2019-3882.

719aee2c5b vfio/type1: Fix unmap overflow off-by-one
commit 58fec830fc upstream.

The below referenced commit adds a test for integer overflow, but in
doing so prevents the unmap ioctl from ever including the last page of
the address space.  Subtract one to compare to the last address of the
unmap to avoid the overflow and wrap-around.

5e2d059b52 powerpc updates for 4.19
Notable changes:
 
  - A fix for a bug in our page table fragment allocator, where a page table page
    could be freed and reallocated for something else while still in use, leading
    to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for
    a powerpc only refcount.
 
  - Fixes to our pkey support. Several are user-visible changes, but bring us in
    to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer
    for reporting many of these.
 
  - A series to improve the hvc driver & related OPAL console code, which have
    been seen to cause hardlockups at times. The hvc driver changes in particular
    have been in linux-next for ~month.
 
  - Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
 
  - Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use
    anywhere other than as a paper weight.
 
  - An optimised memcmp implementation using Power7-or-later VMX instructions
 
  - Support for barrier_nospec on some NXP CPUs.
 
  - Support for flushing the count cache on context switch on some IBM CPUs
    (controlled by firmware), as a Spectre v2 mitigation.
 
  - A series to enhance the information we print on unhandled signals to bring it
    into line with other arches, including showing the offending VMA and dumping
    the instructions around the fault.
