Longfang Liu be1e0287ac hisi_acc_vfio_pci: bugfix the problem of uninstalling driver
[ Upstream commit db6525a8573957faea28850392f4744e5f8f7a53 ]

In a live migration scenario. If the number of VFs at the
destination is greater than the source, the recovery operation
will fail and qemu will not be able to complete the process and
exit after shutting down the device FD.

This will cause the driver to be unable to be unloaded normally due
to abnormal reference counting of the live migration driver caused
by the abnormal closing operation of fd.

Therefore, make sure the migration file descriptor references are
always released when the device is closed.

Longfang Liu bac4641756 hisi_acc_vfio_pci: bugfix cache write-back issue
[ Upstream commit e63c466398731bb7867f42f44b76fa984de59db2 ]

At present, cache write-back is placed in the device data
copy stage after stopping the device operation.
Writing back to the cache at this stage will cause the data
obtained by the cache to be written back to be empty.

In order to ensure that the cache data is written back
successfully, the data needs to be written back into the
stop device stage.

Li RongQing 46e6822489 vfio/type1: Fix error unwind in migration dirty bitmap allocation
[ Upstream commit 4518e5a60c7fbf0cdff393c2681db39d77b4f87e ]

When setting up dirty page tracking at the vfio IOMMU backend for
device migration, if an error is encountered allocating a tracking
bitmap, the unwind loop fails to free previously allocated tracking
bitmaps.  This occurs because the wrong loop index is used to
generate the tracking object.  This results in unintended memory
usage for the life of the current DMA mappings where bitmaps were
successfully allocated.

Use the correct loop index to derive the tracking object for
freeing during unwind.

Longfang Liu 59a834592d hisi_acc_vfio_pci: bugfix live migration function without VF device driver
[ Upstream commit 2777a40998deb36f96b6afc48bd397cf58a4edf0 ]

If the VF device driver is not loaded in the Guest OS and we attempt to
perform device data migration, the address of the migrated data will
be NULL.
The live migration recovery operation on the destination side will
access a null address value, which will cause access errors.

Therefore, live migration of VMs without added VF device drivers
does not require device data migration.
In addition, when the queue address data obtained by the destination
is empty, device queue recovery processing will not be performed.

[ Upstream commit 3495cec0787721ba7a9d5c19d0bbb66d182de584 ]

In order to ensure that the task packets of the accelerator
device are not lost during the migration process, it is necessary
to send an EQ and AEQ command to the device after the live migration
is completed and to update the completion position of the task queue.

Let the device recheck the completed tasks data and if there are
uncollected packets, device resend a task completion interrupt
to the software.

Longfang Liu 884a76e813 hisi_acc_vfio_pci: fix XQE dma address error
[ Upstream commit 8bb7170c5a055ea17c6857c256ee73c10ff872eb ]

The dma addresses of EQE and AEQE are wrong after migration and
results in guest kernel-mode encryption services  failure.
Comparing the definition of hardware registers, we found that
there was an error when the data read from the register was
combined into an address. Therefore, the address combination
sequence needs to be corrected.

Even after fixing the above problem, we still have an issue
where the Guest from an old kernel can get migrated to
new kernel and may result in wrong data.

In order to ensure that the address is correct after migration,
if an old magic number is detected, the dma address needs to be
updated.

Alex Williamson 66e8f1d64b vfio/pci: Handle INTx IRQ_NOTCONNECTED
[ Upstream commit 860be250fc32de9cb24154bf21b4e36f40925707 ]

Some systems report INTx as not routed by setting pdev->irq to
IRQ_NOTCONNECTED, resulting in a -ENOTCONN error when trying to
setup eventfd signaling.  Include this in the set of conditions
for which the PIN register is virtualized to zero.

Additionally consolidate vfio_pci_get_irq_count() to use this
virtualized value in reporting INTx support via ioctl and sanity
checking ioctl paths since pdev->irq is re-used when the device
is in MSI mode.

The combination of these results in both the config space of the
device and the ioctl interface behaving as if the device does not
support INTx.

Alex Williamson afa5cdce06 vfio/pci: Align huge faults to order
commit c1d9dac0db168198b6f63f460665256dedad9b6e upstream.

The vfio-pci huge_fault handler doesn't make any attempt to insert a
mapping containing the faulting address, it only inserts mappings if the
faulting address and resulting pfn are aligned.  This works in a lot of
cases, particularly in conjunction with QEMU where DMA mappings linearly
fault the mmap.  However, there are configurations where we don't get
that linear faulting and pages are faulted on-demand.

The scenario reported in the bug below is such a case, where the physical
address width of the CPU is greater than that of the IOMMU, resulting in a
VM where guest firmware has mapped device MMIO beyond the address width of
the IOMMU.  In this configuration, the MMIO is faulted on demand and
tracing indicates that occasionally the faults generate a VM_FAULT_OOM.
Given the use case, this results in a "error: kvm run failed Bad address",
killing the VM.

The host is not under memory pressure in this test, therefore it's
suspected that VM_FAULT_OOM is actually the result of a NULL return from
__pte_offset_map_lock() in the get_locked_pte() path from insert_pfn().
This suggests a potential race inserting a pte concurrent to a pmd, and
maybe indicates some deficiency in the mm layer properly handling such a
case.

Nevertheless, Peter noted the inconsistency of vfio-pci's huge_fault
handler where our mapping granularity depends on the alignment of the
faulting address relative to the order rather than aligning the faulting
address to the order to more consistently insert huge mappings.  This
change not only uses the page tables more consistently and efficiently, but
as any fault to an aligned page results in the same mapping, the race
condition suspected in the VM_FAULT_OOM is avoided.

Ankit Agrawal 44e35bfd2e vfio/nvgrace-gpu: Expose the blackwell device PF BAR1 to the VM
[ Upstream commit 6a9eb2d125ba90d13b45bcfabcddf9f61268f6a8 ]

There is a HW defect on Grace Hopper (GH) to support the
Multi-Instance GPU (MIG) feature [1] that necessiated the presence
of a 1G region carved out from the device memory and mapped as
uncached. The 1G region is shown as a fake BAR (comprising region 2 and 3)
to workaround the issue.

The Grace Blackwell systems (GB) differ from GH systems in the following
aspects:
1. The aforementioned HW defect is fixed on GB systems.
2. There is a usable BAR1 (region 2 and 3) on GB systems for the
GPUdirect RDMA feature [2].

This patch accommodate those GB changes by showing the 64b physical
device BAR1 (region2 and 3) to the VM instead of the fake one. This
takes care of both the differences.

Moreover, the entire device memory is exposed on GB as cacheable to
the VM as there is no carveout required.

Ankit Agrawal 18457b697f vfio/nvgrace-gpu: Read dvsec register to determine need for uncached resmem
[ Upstream commit bd53764a60ad586ad5b6ed339423ad5e67824464 ]

NVIDIA's recently introduced Grace Blackwell (GB) Superchip is a
continuation with the Grace Hopper (GH) superchip that provides a
cache coherent access to CPU and GPU to each other's memory with
an internal proprietary chip-to-chip cache coherent interconnect.

There is a HW defect on GH systems to support the Multi-Instance
GPU (MIG) feature [1] that necessiated the presence of a 1G region
with uncached mapping carved out from the device memory. The 1G
region is shown as a fake BAR (comprising region 2 and 3) to
workaround the issue. This is fixed on the GB systems.

The presence of the fix for the HW defect is communicated by the
device firmware through the DVSEC PCI config register with ID 3.
The module reads this to take a different codepath on GB vs GH.

Scan through the DVSEC registers to identify the correct one and use
it to determine the presence of the fix. Save the value in the device's
nvgrace_gpu_pci_core_device structure.

Ramesh Thomas 758a5e1dc6 vfio/pci: Enable iowrite64 and ioread64 for vfio pci
[ Upstream commit 2b938e3db335e3670475e31a722c2bee34748c5a ]

Definitions of ioread64 and iowrite64 macros in asm/io.h called by vfio
pci implementations are enclosed inside check for CONFIG_GENERIC_IOMAP.
They don't get defined if CONFIG_GENERIC_IOMAP is defined. Include
linux/io-64-nonatomic-lo-hi.h to define iowrite64 and ioread64 macros
when they are not defined. io-64-nonatomic-lo-hi.h maps the macros to
generic implementation in lib/iomap.c. The generic implementation does
64 bit rw if readq/writeq is defined for the architecture, otherwise it
would do 32 bit back to back rw.

Note that there are two versions of the generic implementation that
differs in the order the 32 bit words are written if 64 bit support is
not present. This is not the little/big endian ordering, which is
handled separately. This patch uses the lo followed by hi word ordering
which is consistent with current back to back implementation in the
vfio/pci code.

commit ce9ff21ea89d191e477a02ad7eabf4f996b80a69 upstream.

count and offset are passed from user space and not checked, only
offset is capped to 40 bits, which can be used to read/write out of
bounds of the device.

Mostafa Saleh 0ef77a1bee ANDROID: drivers/vfio: Add VFIO_PKVM_IOMMU
pKVM provides mutual distrust between host kernel and protected VMs(pVM)
One solution to provide DMA isolation in this model, is to move the IOMMU
control to the hypervisor and para-virtualize the IOMMU interface for
the host and guest kernel. (none of them have direct access to IOMMU
programming interface).
In the case of device assignement, the host can't map memory in for the
guest kernel (as it is not trusted).
So, what mainly needs to be done is to assign a blocking domain, when
VFIO assigns the device to user space, so it can't issue any DMA, and
when the guest take control it can program the IOMMU through hypervisor
with collapsed translation (IOVA->PA directly).

Mostafa Saleh 89f90d9773 ANDROID: KVM: Add arch function for device assignment
Add arch specific functions to notify KVM about device/group assignment
to KVM.
pKVM would use this to assign devices at once, as this is a requirement
for pVM device passthrough, that all devices have to be donated first
before the VM using them.
That allow the hypervisor to properly reset the device, and prevent
situations where a devices is not fully owned by pVM.

Yishai Hadas ad4095d125 vfio/mlx5: Align the page tracking max message size with the device capability
[ Upstream commit 9c7c5430bca36e9636eabbba0b3b53251479c7ab ]

Align the page tracking maximum message size with the device's
capability instead of relying on PAGE_SIZE.

This adjustment resolves a mismatch on systems where PAGE_SIZE is 64K,
but the firmware only supports a maximum message size of 4K.

Now that we rely on the device's capability for max_message_size, we
must account for potential future increases in its value.

Key considerations include:
- Supporting message sizes that exceed a single system page (e.g., an 8K
  message on a 4K system).
- Ensuring the RQ size is adjusted to accommodate at least 4
  WQEs/messages, in line with the device specification.

The above has been addressed as part of the patch.

Giovanni Cabiddu 15bfacdb85 vfio/qat: fix overflow check in qat_vf_resume_write()
commit 9283b7392570421c22a6c8058614f5b76a46b81c upstream.

The unsigned variable `size_t len` is cast to the signed type `loff_t`
when passed to the function check_add_overflow(). This function considers
the type of the destination, which is of type loff_t (signed),
potentially leading to an overflow. This issue is similar to the one
described in the link below.

Remove the cast.

Note that even if check_add_overflow() is bypassed, by setting `len` to
a value that is greater than LONG_MAX (which is considered as a negative
value after the cast), the function copy_from_user(), invoked a few lines
later, will not perform any copy and return `len` as (len > INT_MAX)
causing qat_vf_resume_write() to fail with -EFAULT.

Avihai Horon 1ef195178f vfio/pci: Properly hide first-in-list PCIe extended capability
[ Upstream commit fe4bf8d0b6716a423b16495d55b35d3fe515905d ]

There are cases where a PCIe extended capability should be hidden from
the user. For example, an unknown capability (i.e., capability with ID
greater than PCI_EXT_CAP_ID_MAX) or a capability that is intentionally
chosen to be hidden from the user.

Hiding a capability is done by virtualizing and modifying the 'Next
Capability Offset' field of the previous capability so it points to the
capability after the one that should be hidden.

The special case where the first capability in the list should be hidden
is handled differently because there is no previous capability that can
be modified. In this case, the capability ID and version are zeroed
while leaving the next pointer intact. This hides the capability and
leaves an anchor for the rest of the capability list.

However, today, hiding the first capability in the list is not done
properly if the capability is unknown, as struct
vfio_pci_core_device->pci_config_map is set to the capability ID during
initialization but the capability ID is not properly checked later when
used in vfio_config_do_rw(). This leads to the following warning [1] and
to an out-of-bounds access to ecap_perms array.

Fix it by checking cap_id in vfio_config_do_rw(), and if it is greater
than PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for direct
read only access instead of the ecap_perms array.

Note that this is safe since the above is the only case where cap_id can
exceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, which
are already checked before).

Al Viro cb787f4ac0 [tree-wide] finally take no_llseek out
no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

Alex Williamson f9e54c3a2f vfio/pci: implement huge_fault support
With the addition of pfnmap support in vmf_insert_pfn_{pmd,pud}() we can
take advantage of PMD and PUD faults to PCI BAR mmaps and create more
efficient mappings.  PCI BARs are always a power of two and will typically
get at least PMD alignment without userspace even trying.  Userspace
alignment for PUD mappings is also not too difficult.

Consolidate faults through a single handler with a new wrapper for
standard single page faults.  The pre-faulting behavior of commit
d71a989cf5 ("vfio/pci: Insert full vma on mmap'd MMIO fault") is removed
in this refactoring since huge_fault will cover the bulk of the faults and
results in more efficient page table usage.  We also want to avoid that
pre-faulted single page mappings preempt huge page mappings.

Al Viro 1da91ea87a introduce fd_file(), convert all accessors to it.
For any changes of struct fd representation we need to
turn existing accesses to fields into calls of wrappers.
Accesses to struct fd::flags are very few (3 in linux/file.h,
1 in net/socket.c, 3 in fs/overlayfs/file.c and 3 more in
explicit initializers).
	Those can be dealt with in the commit converting to
new layout; accesses to struct fd::file are too many for that.
	This commit converts (almost) all of f.file to
fd_file(f).  It's not entirely mechanical ('file' is used as
a member name more than just in struct fd) and it does not
even attempt to distinguish the uses in pointer context from
those in boolean context; the latter will be eventually turned
into a separate helper (fd_empty()).

	NOTE: mass conversion to fd_empty(), tempting as it
might be, is a bad idea; better do that piecewise in commit
that convert from fdget...() to CLASS(...).

Linus Torvalds c2a96b7f18 Merge tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
 "Here is the big set of driver core changes for 6.11-rc1.

  Lots of stuff in here, with not a huge diffstat, but apis are evolving
  which required lots of files to be touched. Highlights of the changes
  in here are:

   - platform remove callback api final fixups (Uwe took many releases
     to get here, finally!)

   - Rust bindings for basic firmware apis and initial driver-core
     interactions.

     It's not all that useful for a "write a whole driver in rust" type
     of thing, but the firmware bindings do help out the phy rust
     drivers, and the driver core bindings give a solid base on which
     others can start their work.

     There is still a long way to go here before we have a multitude of
     rust drivers being added, but it's a great first step.

   - driver core const api changes.

     This reached across all bus types, and there are some fix-ups for
     some not-common bus types that linux-next and 0-day testing shook
     out.

     This work is being done to help make the rust bindings more safe,
     as well as the C code, moving toward the end-goal of allowing us to
     put driver structures into read-only memory. We aren't there yet,
     but are getting closer.

   - minor devres cleanups and fixes found by code inspection

   - arch_topology minor changes

   - other minor driver core cleanups

  All of these have been in linux-next for a very long time with no
  reported problems"

Greg Kroah-Hartman d69d804845 driver core: have match() callback in struct bus_type take a const *
In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *.  This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.

Because the match() callback is in all busses, all busses are modified
to handle this properly.  This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.

For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

Shivaprasad G Bhat 4ba2fdff2e vfio/spapr: Always clear TCEs before unsetting the window
The PAPR expects the TCE table to have no entries at the time of
unset window(i.e. remove-pe). The TCE clear right now is done
before freeing the iommu table. On pSeries, the unset window
makes those entries inaccessible to the OS and the H_PUT/GET calls
fail on them with H_CONSTRAINED.

On PowerNV, this has no side effect as the TCE clear can be done
before the DMA window removal as well.
