[PATCH v2 0/6] PCI/VPD: pci_vpd_size() cleanups

[Bjorn Helgaas <helgaas@kernel.org>]

From: Bjorn Helgaas <bhelgaas@google.com>

The basic idea is to validate VPD resource *size* without validating the
actual content, since the kernel really doesn't care about the content.

Thanks very much for the feedback on v1, and I'd be glad for any additional
feedback.

Follow-up to:
https://lore.kernel.org/r/20210715215959.2014576-1-helgaas@kernel.org

Changes since v1:
  - Incorporate Heiner's patch to reject VPD if first byte is 0x00 or 0xff
    (https://lore.kernel.org/r/8de8c906-9284-93b9-bb44-4ffdc3470740@gmail.com/)
  - Update size checks to reject resources that would extend past the
    maximum VPD size

Bjorn Helgaas (5):
  PCI/VPD: Correct diagnostic for VPD read failure
  PCI/VPD: Check Resource Item Names against those valid for type
  PCI/VPD: Reject resource tags with invalid size
  PCI/VPD: Don't check Large Resource Item Names for validity
  PCI/VPD: Allow access to valid parts of VPD if some is invalid

Heiner Kallweit (1):
  PCI/VPD: Treat initial 0xff as missing EEPROM
