This patchset defines a denylist of devices in the vfio-pci module and adds
the current generation of Intel(R) QuickAssist devices to it as they are
not designed to run in an untrusted environment.
By default, if a device is in the denylist, the probe of vfio-pci fails.
If a user wants to use a device in the denylist, he needs to disable the
full denylist providing the option disable_denylist=1 at the load of
vfio-pci or specifying that parameter in a config file in /etc/modprobe.d.
This series also moves the device ids definitions present in the qat driver
to linux/pci_ids.h since they will be shared between the vfio-pci and the qat
drivers and replaces the custom ADF_SYSTEM_DEVICE macro with PCI_VDEVICE.
The series is applicable to Herbert's tree. Patches 1 to 3 apply also to
Alex's tree (next). Patches 4 and 5 are optional and can be applied at a later
stage.
Changes from v3:
- Patch #1: included Acked-by tag, after ack from Bjorn Helgaas
- Patch #2: s/prevents/allows/ in module parameter description
Changes from v2:
- Renamed blocklist in denylist
- Patch #2: reworded module parameter description to clarify why a device is
in the denylist
- Patch #2: reworded warning that occurs when denylist is enabled and device
is present in that list
Changes from v1:
- Reworked commit messages:
Patches #1, #2 and #3: capitalized first character after column to comply to
subject line convention
Patch #3: Capitalized QAT acronym and added link and doc number for document
"Intel® QuickAssist Technology (Intel® QAT) Software for Linux"

2.26.2
Add device IDs for the following Intel QuickAssist devices: DH895XCC,
C3XXX and C62X.
The defines in this patch are going to be referenced in two independent
drivers, qat and vfio-pci.

2.26.2
Add denylist of devices that by default are not probed by vfio-pci.
Devices in this list may be susceptible to untrusted application, even
if the IOMMU is enabled. To be accessed via vfio-pci, the user has to
explicitly disable the denylist.
The denylist can be disabled via the module parameter disable_denylist.

2.26.2
The current generation of Intel® QuickAssist Technology devices
are not designed to run in an untrusted environment because of the
following issues reported in the document "Intel® QuickAssist Technology
(Intel® QAT) Software for Linux" (document number 336211-014):
QATE-39220 - GEN - Intel® QAT API submissions with bad addresses that
trigger DMA to invalid or unmapped addresses can cause a
platform hang
QATE-7495 - GEN - An incorrectly formatted request to Intel® QAT can
hang the entire Intel® QAT Endpoint
The document is downloadable from https://01.org/intel-quickassist-technology
at the following link:
https://01.org/sites/default/files/downloads/336211-014-qatforlinux-releasenotes-hwv1.7_0.pdf
This patch adds the following QAT devices to the denylist: DH895XCC,
C3XXX and C62X.

Build pci_device_id structure using the PCI_VDEVICE macro.
This removes any references to the ADF_SYSTEM_DEVICE macro.

> Subject: [PATCH v4 0/5] vfio/pci: add denylist and disable qat
>
> This patchset defines a denylist of devices in the vfio-pci module and adds
> the current generation of Intel(R) QuickAssist devices to it as they are
> not designed to run in an untrusted environment.
>
> By default, if a device is in the denylist, the probe of vfio-pci fails.
> If a user wants to use a device in the denylist, he needs to disable the
> full denylist providing the option disable_denylist=1 at the load of
> vfio-pci or specifying that parameter in a config file in /etc/modprobe.d.
>
> This series also moves the device ids definitions present in the qat driver
> to linux/pci_ids.h since they will be shared between the vfio-pci and the qat
> drivers and replaces the custom ADF_SYSTEM_DEVICE macro with PCI_VDEVICE.
>
> The series is applicable to Herbert's tree. Patches 1 to 3 apply also to
> Alex's tree (next). Patches 4 and 5 are optional and can be applied at a later
> stage.
>
> Changes from v3:
> - Patch #1: included Acked-by tag, after ack from Bjorn Helgaas
> - Patch #2: s/prevents/allows/ in module parameter description
>
> Changes from v2:
> - Renamed blocklist in denylist
> - Patch #2: reworded module parameter description to clarify why a device is
> in the denylist
> - Patch #2: reworded warning that occurs when denylist is enabled and device
> is present in that list
>
> Changes from v1:
> - Reworked commit messages:
> Patches #1, #2 and #3: capitalized first character after column to comply to
> subject line convention
> Patch #3: Capitalized QAT acronym and added link and doc number for document
> "Intel® QuickAssist Technology (Intel® QAT) Software for Linux"
>
> Giovanni Cabiddu (5):
> PCI: Add Intel QuickAssist device IDs
> vfio/pci: Add device denylist
> vfio/pci: Add QAT devices to denylist
> crypto: qat - replace device ids defines
> crypto: qat - use PCI_VDEVICE
