The driver can't read/write from i2c if the device is in reset or

cffaaf0c81 iommu/dmar: Fix buffer overflow during PCI bus notification
Commit 57384592c4 ("iommu/vt-d: Store bus information in RMRR PCI
device path") changed the type of the path data, however, the change in
path type was not reflected in size calculations.  Update to use the
correct type and prevent a buffer overflow.

This bug manifests in systems with deep PCI hierarchies, and can lead to
an overflow of the static allocated buffer (dmar_pci_notify_info_buf),
or can lead to overflow of slab-allocated data.

A change made in the final version of IOMMU debugfs support replaced the
public function iommu_debugfs_new_driver_dir() by the public dentry
iommu_debugfs_dir in <linux/iommu.h>, but forgot to update both the

Fix this by exporting iommu_debugfs_dir, and removing the reference to

61363c1474 iommu/vt-d: Enable ATS only if the device uses page aligned address.
As per Intel vt-d specification, Rev 3.0 (section 7.5.1.1, title "Page
Request Descriptor"), Intel IOMMU page request descriptor only uses
bits[63:12] of the page address. Hence Intel IOMMU driver would only
permit devices that advertise they would only send Page Aligned Requests
to participate in ATS service.

Return the Page Aligned Request bit in the ATS Capability Register.

As per PCIe spec r4.0, sec 10.5.1.2, if the Page Aligned Request bit is
set, it indicates the Untranslated Addresses generated by the device are
always aligned to a 4096 byte boundary.

An IOMMU that can only translate page-aligned addresses can only be used
with devices that always produce aligned Untranslated Addresses. This
interface will be used by drivers for such IOMMUs to determine whether
devices can use the ATS service.

1b84778a62 iommu/vt-d: Fix PRI/PASID dependency issue.
In Intel IOMMU, if the Page Request Queue (PRQ) is full, it will
automatically respond to the device with a success message as a keep
alive. And when sending the success message, IOMMU will include PASID in
the Response Message when the Page Request has a PASID in Request
Message and it does not check against the PRG Response PASID requirement
of the device before sending the response. Also, if the device receives
the PRG response with PASID when its not expecting it the device behavior
is undefined. So if PASID is enabled in the device, enable PRI only if
device expects PASID in PRG Response Message.

e5567f5f67 PCI/ATS: Add pci_prg_resp_pasid_required() interface.
Return the PRG Response PASID Required bit in the Page Request
Status Register.

As per PCIe spec r4.0, sec 10.5.2.3, if this bit is Set, the device
expects a PASID TLP Prefix on PRG Response Messages when the
corresponding Page Requests had a PASID TLP Prefix. If Clear, the device
does not expect PASID TLP Prefixes on any PRG Response Message, and the
device behavior is undefined if the device receives a PRG Response Message
with a PASID TLP Prefix. Also the device behavior is undefined if this
bit is Set and the device receives a PRG Response Message with no PASID TLP
Prefix when the corresponding Page Requests had a PASID TLP Prefix.

This function will be used by drivers like IOMMU, if it is required to
check the status of the PRG Response PASID Required bit before enabling
the PASID support of the device.

3f0c625c6a iommu/vt-d: Allow interrupts from the entire bus for aliased devices
When a device has multiple aliases that all are from the same bus,
we program the IRTE to accept requests from any matching device on the
bus.

This is so NTB devices which can have requests from multiple bus-devfns
can pass MSI interrupts through across the bridge.

9ca8261173 iommu/vt-d: Add helper to set an IRTE to verify only the bus number
The current code uses set_irte_sid() with SVT_VERIFY_BUS and PCI_DEVID
to set the SID value. However, this is very confusing because, with
SVT_VERIFY_BUS, the SID value is not a PCI devfn address, but the start
and end bus numbers to match against.

According to the Intel Virtualization Technology for Directed I/O
Architecture Specification, Rev. 3.0, page 9-36:

  The most significant 8-bits of the SID field contains the Startbus#,
  and the least significant 8-bits of the SID field contains the Endbus#.
  Interrupt requests that reference this IRTE must have a requester-id
  whose bus# (most significant 8-bits of requester-id) has a value equal
  to or within the Startbus# to Endbus# range.

So to make this more clear, introduce a new set_irte_verify_bus() that
explicitly takes a start bus and end bus so that we can stop abusing
the PCI_DEVID macro.

This helper function will be called a second time in an subsequent patch.

context in which this code is being used.

So, change the following form:

sizeof(*rp) + (sizeof(rp->entry[0]) * count);

to :

struct_size(rp, entry, count)

Notice that, in this case, variable rp_len is not necessary, hence
it is removed.

This code was detected with the help of Coccinelle.

f97a0944a7 ALSA: firewire-motu: fix construction of PCM frame for capture direction
In data blocks of common isochronous packet for MOTU devices, PCM
frames are multiplexed in a shape of '24 bit * 4 Audio Pack', described
in IEC 61883-6. The frames are not aligned to quadlet.

For capture PCM substream, ALSA firewire-motu driver constructs PCM
frames by reading data blocks byte-by-byte. However this operation
includes bug for lower byte of the PCM sample. This brings invalid
content of the PCM samples.

This commit fixes the bug.

7dc661bd8d ALSA: bebob: use more identical mod_alias for Saffire Pro 10 I/O against Liquid Saffire 56
ALSA bebob driver has an entry for Focusrite Saffire Pro 10 I/O. The
entry matches vendor_id in root directory and model_id in unit
directory of configuration ROM for IEEE 1394 bus.

On the other hand, configuration ROM of Focusrite Liquid Saffire 56
has the same vendor_id and model_id. This device is an application of
TCAT Dice (TCD2220 a.k.a Dice Jr.) however ALSA bebob driver can be
bound to it randomly instead of ALSA dice driver. At present, drivers
in ALSA firewire stack can not handle this situation appropriately.

This commit uses more identical mod_alias for Focusrite Saffire Pro 10
I/O in ALSA bebob driver.

5330367fa3 powerpc/hugetlb: Handle mmap_min_addr correctly in get_unmapped_area callback
After we ALIGN up the address we need to make sure we didn't overflow
and resulted in zero address. In that case, we need to make sure that
the returned address is greater than mmap_min_addr.

This fixes selftest va_128TBswitch --run-hugetlb reporting failures when
run as non root user for

mmap(-1, MAP_HUGETLB)

The bug is that a non-root user requesting address -1 will be given address 0
which will then fail, whereas they should have been given something else that
would have succeeded.

We also avoid the first mmap(-1, MAP_HUGETLB) returning NULL address as mmap address
with this change. So we think this is not a security issue, because it only affects
whether we choose an address below mmap_min_addr, not whether we
actually allow that address to be mapped. ie. there are existing capability
checks to prevent a user mapping below mmap_min_addr and those will still be
honoured even without this fix.
