[edk2-devel] [PATCH v5 0/6] Extend Last Attempt Status Usage

Posted by Michael Kubacki 6 days ago
From: Michael Kubacki <michael.kubacki@microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2802

This patch series adds more granularity to Last Attempt Status
codes reported during FMP check image and set image operations
that greatly improve precision of the status codes.

The unsuccessful vendor range (0x1000 - 0x4000) was introduced
in UEFI Specification 2.8. At a high-level, two subranges are
defined within that range in this patch series:
  1. The FMP Reserved range - reserved for components implemented
     in FmpDevicePkg.
  2. The FMP Device Library Reserved range - reserved for
     FmpDeviceLib instance-specific usage.

The ranges are described in a public header file LastAttemptStatus.h
while the specific codes used within FmpDevicePkg implementation
are defined in a private header file FmpLastAttemptStatus.h.

FmpDeviceLib instances should use the range definition from the
public header file to define Last Attempt Status codes local to
their library instance.

Of note, there's multiple approaches to assigning private status
codes in the FMP Reserved range. For example, individual components
could define their last attempt status codes locally with the
range allocated to the component defined in a package-wide private
header file. However, one goal of the granularity being introduced
is to provide straightforward traceability to an error source.

For that reason, it was chosen to define a constant set of codes at
the package level in FmpLastAttemptStatus.h. For example, if a new
FmpDependencyLib instance is added, it would not be able to reassign
status code values in the pre-existing FMP Dependency range; it
would reuse codes for the same error source and be able to add new
codes onto the range for its usage.

V5 changes:
  1. Fixed an issue where
     LAST_ATTEMPT_STATUS_DRIVER_ERROR_INVALID_CERTIFICATE is changed
     to LAST_ATTEMPT_STATUS_DRIVER_ERROR_IMAGE_AUTH_FAILURE in the
     logic to return the last attempt status code in
     CheckTheImageInternal().

V4 changes:
  1. Simplified range value definitions in LastAttemptStatus.h.
     Directly assign the values in the macro definition instead
     of using calculations.
  2. Adjusted range sizes to leave more room for future expansion.

     OLD:
     START     | END       | Usage
     ------------------------------------------------|
     0x1000    | 0x1FFF    | FmpDevicePkg            |
        0x1000 |    0x107F | FmpDxe driver           |
        0x1080 |    0x109F | FMP dependency Libs     |
     0x2000    | 0x3FFF    | FmpDeviceLib instances  |

     NEW:
     START     | END       | Usage
     ----------------------------------------------------------------|
     0x1000    | 0x17FF    | FmpDevicePkg                            |
        0x1000 |    0x107F | FmpDxe driver                           |
        0x1080 |    0x109F | FmpDependencyLib                        |
        0x10A0 |    0x10BF | FmpDependencyCheckLib                   |
        0x10C0 |    0x17FF | Unused. Available for future expansion. |
     0x1800    | 0x1FFF    | FmpDeviceLib instances implementation   |
     0x2000    | 0x3FFF    | Unused. Available for future expansion. |

  3. Broke the single range in v3 for FMP Dependency libraries into
     separate ranges.
  4. Clarified LastAttemptStatus return values in each function
     description.
  5. Returned an expected LastAttemptStatus value for some functions
     that previously did not return a value.
  6. Reverted changes in FmpDxe to call the new FmpDeviceLib APIs
     for FmpDeviceCheckImage () and FmpDeviceSetImage (). These will
     be added in a future series after impacted platforms in
     edk2-platforms are updated to use the new APIs.
  7. Instead of directly changing the pre-existing APIs in
     FmpDeviceLib to add a LastAttemptStatus parameter, the new
     functions were added to the library interface:
       * FmpDeviceCheckImageWithStatus ()
       * FmpDeviceSetImageWithStatus ()

V3 changes:
  1. Enhanced range definitions in LastAttemptStatus.h with more
     completeness providing length, min, and max values.
  2. Moved the actual Last Attempt Status code assignments to a
     private header file PrivateInclude/FmpLastAttemptStatus.h.
  3. Changed the value of
     LAST_ATTEMPT_STATUS_ERROR_UNSUCCESSFUL_VENDOR_RANGE_MAX
     to 0x3FFF instead of 0x4000 even though 0x4000 is defined in
     the UEFI specification. The length is 0x4000 but the max
     allowed value should be 0x3FFF. This change was made now to
     prevent implementation compatibility issues in the future.
  4. Included "DEVICE" in the following macro name to clearly
     associate it with the FmpDeviceLib library class:
     LAST_ATTEMPT_STATUS_DEVICE_LIBRARY_ERROR_xxx
  5. Included a map to help the reader better visualize the range
     definitions in LastAttemptStatus.h.
  6. Included additional documentation describing the enum in
     FmpLastAttemptStatus.h. An explicit statement stating that new
     codes should be added onto the end of ranges to preserve the
     values was added.
  7. Simplified error handling logic in FmpDxe for FmpDeviceLib
     calls that return Last Attempt Status.
  8. V2 had a single memory allocation failure code used for
     different memory allocations in CheckFmpDependency () in
     FmpDependencyLib. Each potential allocation failure was
     assigned a unique code.

V2 changes:
  1. Consolidate all previous incremental updates to 
     LastAttemptStatus.h into one patch (patch 2)
  2. Move LastAttemptStatus.h from Include to PrivateInclude
  3. Correct patch 1 subject from "FmpDevicePkg" to "MdePkg"

Re: [edk2-devel] [PATCH v5 0/6] Extend Last Attempt Status Usage

Posted by Michael D Kinney 5 days ago
Hi Michael,

Thank you for the updates.  This feedback was meant for V5, and not V4.

A couple minor comments:

1) FmpDevicePkg/Library/FmpDeviceLibNull

   In order to demonstrate the preferred implementation I think we should
   have FmpDeviceCheckImage() call FmpDeviceCheckImageWithStatus() and
   FmpDeviceSetImage() call FmpDeviceSetImageWithStatus().  This way, it
   will be clear to FmpDeviceLib developers that they only need to 
   implement the *WithStatus() version.

2) FmpDevicePkg/PrivateInclude/FmpLastAttemptStatus.h

   FmpDependencyCheckLib comment block should use /// instead of // to be
   consistent with the rest of the include file.

Thanks,

Mike

>> Subject: [PATCH v5 0/6] Extend Last Attempt Status Usage
>>
>> From: Michael Kubacki <michael.kubacki@microsoft.com>
>>
>> REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2802
>>
>> This patch series adds more granularity to Last Attempt Status
>> codes reported during FMP check image and set image operations
>> that greatly improve precision of the status codes.
>>
>> The unsuccessful vendor range (0x1000 - 0x4000) was introduced
>> in UEFI Specification 2.8. At a high-level, two subranges are
>> defined within that range in this patch series:
>>    1. The FMP Reserved range - reserved for components implemented
>>       in FmpDevicePkg.
>>    2. The FMP Device Library Reserved range - reserved for
>>       FmpDeviceLib instance-specific usage.
>>
>> The ranges are described in a public header file LastAttemptStatus.h
>> while the specific codes used within FmpDevicePkg implementation
>> are defined in a private header file FmpLastAttemptStatus.h.
>>
>> FmpDeviceLib instances should use the range definition from the
>> public header file to define Last Attempt Status codes local to
>> their library instance.
>>
>> Of note, there's multiple approaches to assigning private status
>> codes in the FMP Reserved range. For example, individual components
>> could define their last attempt status codes locally with the
>> range allocated to the component defined in a package-wide private
>> header file. However, one goal of the granularity being introduced
>> is to provide straightforward traceability to an error source.
>>
>> For that reason, it was chosen to define a constant set of codes at
>> the package level in FmpLastAttemptStatus.h. For example, if a new
>> FmpDependencyLib instance is added, it would not be able to reassign
>> status code values in the pre-existing FMP Dependency range; it
>> would reuse codes for the same error source and be able to add new
>> codes onto the range for its usage.
>>
>> V5 changes:
>>    1. Fixed an issue where
>>       LAST_ATTEMPT_STATUS_DRIVER_ERROR_INVALID_CERTIFICATE is changed
>>       to LAST_ATTEMPT_STATUS_DRIVER_ERROR_IMAGE_AUTH_FAILURE in the
>>       logic to return the last attempt status code in
>>       CheckTheImageInternal().
>>
>> V4 changes:
>>    1. Simplified range value definitions in LastAttemptStatus.h.
>>       Directly assign the values in the macro definition instead
>>       of using calculations.
>>    2. Adjusted range sizes to leave more room for future expansion.
>>
>>       OLD:
>>       START     | END       | Usage
>>       ------------------------------------------------|
>>       0x1000    | 0x1FFF    | FmpDevicePkg            |
>>          0x1000 |    0x107F | FmpDxe driver           |
>>          0x1080 |    0x109F | FMP dependency Libs     |
>>       0x2000    | 0x3FFF    | FmpDeviceLib instances  |
>>
>>       NEW:
>>       START     | END       | Usage
>>       ----------------------------------------------------------------|
>>       0x1000    | 0x17FF    | FmpDevicePkg                            |
>>          0x1000 |    0x107F | FmpDxe driver                           |
>>          0x1080 |    0x109F | FmpDependencyLib                        |
>>          0x10A0 |    0x10BF | FmpDependencyCheckLib                   |
>>          0x10C0 |    0x17FF | Unused. Available for future expansion. |
>>       0x1800    | 0x1FFF    | FmpDeviceLib instances implementation   |
>>       0x2000    | 0x3FFF    | Unused. Available for future expansion. |
>>
>>    3. Broke the single range in v3 for FMP Dependency libraries into
>>       separate ranges.
>>    4. Clarified LastAttemptStatus return values in each function
>>       description.
>>    5. Returned an expected LastAttemptStatus value for some functions
>>       that previously did not return a value.
>>    6. Reverted changes in FmpDxe to call the new FmpDeviceLib APIs
>>       for FmpDeviceCheckImage () and FmpDeviceSetImage (). These will
>>       be added in a future series after impacted platforms in
>>       edk2-platforms are updated to use the new APIs.
>>    7. Instead of directly changing the pre-existing APIs in
>>       FmpDeviceLib to add a LastAttemptStatus parameter, the new
>>       functions were added to the library interface:
>>         * FmpDeviceCheckImageWithStatus ()
>>         * FmpDeviceSetImageWithStatus ()
>>
>> V3 changes:
>>    1. Enhanced range definitions in LastAttemptStatus.h with more
>>       completeness providing length, min, and max values.
>>    2. Moved the actual Last Attempt Status code assignments to a
>>       private header file PrivateInclude/FmpLastAttemptStatus.h.
>>    3. Changed the value of
>>       LAST_ATTEMPT_STATUS_ERROR_UNSUCCESSFUL_VENDOR_RANGE_MAX
>>       to 0x3FFF instead of 0x4000 even though 0x4000 is defined in
>>       the UEFI specification. The length is 0x4000 but the max
>>       allowed value should be 0x3FFF. This change was made now to
>>       prevent implementation compatibility issues in the future.
>>    4. Included "DEVICE" in the following macro name to clearly
>>       associate it with the FmpDeviceLib library class:
>>       LAST_ATTEMPT_STATUS_DEVICE_LIBRARY_ERROR_xxx
>>    5. Included a map to help the reader better visualize the range
>>       definitions in LastAttemptStatus.h.
>>    6. Included additional documentation describing the enum in
>>       FmpLastAttemptStatus.h. An explicit statement stating that new
>>       codes should be added onto the end of ranges to preserve the
>>       values was added.
>>    7. Simplified error handling logic in FmpDxe for FmpDeviceLib
>>       calls that return Last Attempt Status.
>>    8. V2 had a single memory allocation failure code used for
>>       different memory allocations in CheckFmpDependency () in
>>       FmpDependencyLib. Each potential allocation failure was
>>       assigned a unique code.
>>
>> V2 changes:
>>    1. Consolidate all previous incremental updates to
>>       LastAttemptStatus.h into one patch (patch 2)
>>    2. Move LastAttemptStatus.h from Include to PrivateInclude
>>    3. Correct patch 1 subject from "FmpDevicePkg" to "MdePkg"
