Subject: [PATCH v5 0/5] vfio/pci: add denylist and disable qat
Date: Fri, 24 Jul 2020 11:55:55 +0100 [thread overview]
Message-ID: <20200724105600.10814-1-giovanni.cabiddu@intel.com> (raw)
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 v4:
- Patch #2: added Reviewed-by tag from Cornelia Huck
- Patch #5: added Suggested-by tag as this change was suggested internally
by Andy Shevchenko
- Patches 1-5: added Reviewed-by tag from Fiona Trahe
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"
