Subject: [PATCH v2 0/7] Tighten PCI security, expose dev location in sysfs
Date: Mon, 29 Jun 2020 21:49:36 -0700
Message-ID: <20200630044943.3425049-1-rajatja@google.com> (raw)

This is a set of loosely related patches most of whom emerged out of
discussion in the following threads. 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
