In a nutshell the goal was to allow an administrator to specify which driver he wants to allow on external ports, and a strategy was chalked out: https://lore.kernel.org/linux-pci/20200609210400.GA1461839@bjorn-Precision-5520/ https://lore.kernel.org/linux-pci/20200618184621.GA446639@kroah.com/ https://lore.kernel.org/linux-pci/20200627050225.GA226238@kroah.com/ * The first 3 patches tighten the PCI security using ACS, and take care of a border case. * The 4th patch takes care of PCI bug. * 5th and 6th patches expose a device's location into the sysfs to allow admin to make decision based on that. * 7th patch is to ensure that the external devices don't bind to drivers during boot. Rajat Jain (7): PCI: Keep the ACS capability offset in device PCI: Set "untrusted" flag for truly external devices only PCI/ACS: Enable PCI_ACS_TB for untrusted/external-facing devices PCI: Add device even if driver attach failed driver core: Add device location to "struct device" and expose it in sysfs PCI: Move pci_dev->untrusted logic to use device location instead PCI: Add parameter to disable attaching external devices drivers/base/core.c | 35 +++++++++++++++++++++++++++++++ drivers/iommu/intel/iommu.c | 31 ++++++++++++++++++--------- drivers/pci/ats.c | 2 +- drivers/pci/bus.c | 13 ++++++------ drivers/pci/of.c | 2 +- drivers/pci/p2pdma.c | 2 +- drivers/pci/pci-acpi.c | 13 ++++++------ drivers/pci/pci-driver.c | 1 + drivers/pci/pci.c | 34 ++++++++++++++++++++++++++---- drivers/pci/pci.h | 3 ++- drivers/pci/probe.c | 20 +++++++++++------- drivers/pci/quirks.c | 19 +++++++++++++---- include/linux/device.h | 42 +++++++++++++++++++++++++++++++++++++ include/linux/device/bus.h | 8 +++++++ include/linux/pci.h | 13 ++++++------ 15 files changed, 191 insertions(+), 47 deletions(-) -- 2.27.0.212.ge8ba1cc988-goog
