[PATCH 00/31] pci vpd: Fix broken XML formatter and refactor questionable error reporting
Posted by Peter Krempa 3 weeks, 5 days ago
The first part of the series fixes the XML formatter of nodedevs to not
generate invalid XML if a PCI device custom field contains '>' which
would be printed unescaped

The rest fixes questionable and broken error reporting from the pci vpd
device code which actually parses the above data.

 https://gitlab.com/pipo.sk/libvirt/-/pipelines/1157912774

Peter Krempa (31):
  virPCIVPDResourceIsValidTextValue: Adjust comment to reflect actual
    code
  util: pcivpd: Refactor virPCIVPDResourceIsValidTextValue
  virNodeDeviceCapVPDFormatCustom*: Escape unsanitized strings
  virNodeDeviceCapVPDFormat: Properly escape system-originated strings
  schema: nodedev: Adjust allowed characters in 'vpdFieldValueFormat'
  tests: Test the previously mishandled PCI VPD characters
  Don't overwrite error message from 'virXPathNodeSet'
  tests: virpcivpdtest: Remove 'testVirPCIVPDReadVPDBytes' case
  util: virpcivpd: Unexport 'virPCIVPDReadVPDBytes'
  util: pcivpd: Unexport virPCIVPDParseVPDLargeResourceFields
  tests: virpcivpd: Remove 'testVirPCIVPDParseVPDStringResource' case
  util: virpcivpd: Unexport 'virPCIVPDParseVPDLargeResourceString'
  virPCIVPDResourceGetKeywordPrefix: Fix logging
  util: virpcivpd: Remove return value from
    virPCIVPDResourceCustomUpsertValue
  conf: virNodeDeviceCapVPDParse*: Remove pointless NULL checks
  virpcivpdtest: testPCIVPDResourceBasic: Remove tests for uninitialized
    'ro'/'rw' section
  util: virPCIVPDResourceUpdateKeyword: Remove impossible checks
  conf: node_device: Refactor 'virNodeDeviceCapVPDParseCustomFields' to
    fix error reporting
  virNodeDeviceCapVPDParseXML: Fix error reporting
  util: virpcivpd: Remove return value from
    virPCIVPDResourceUpdateKeyword
  virPCIDeviceHasVPD: Refactor "debug" messages
  virPCIDeviceGetVPD: Fix multiple error handling bugs
  virPCIDeviceGetVPD: Handle errors in callers
  virPCIVPDReadVPDBytes: Refactor error handling
  virPCIVPDParseVPDLargeResourceString: Properly report errors
  virPCIVPDParseVPDLargeResourceFields: Merge logic conditions
  virPCIVPDParseVPDLargeResourceFields: Remove impossible 'default'
    swithch case
  virPCIVPDParseVPDLargeResourceFields: Refactor processing of read data
  virPCIVPDParseVPDLargeResourceFields: Refactor return logic
  virPCIVPDParseVPDLargeResourceFields: Report proper errors
  virPCIVPDParse: Do reasonable error reporting
