[PATCH V3 0/5] Adding necessary changes for RedfishPkg

[Minh Nguyen]

This patchset adds necessary changes for RedfishPkg to avoid some unexpected cases and fix compilation.

Changes since v3:
 + Replaced __FUNCTION__ with __func__ to be more C11 compliant.
Changes since v2:
 + Added "Cc:" to maintainers in commit message.
 + Corrected patch format subject prefix.
Changes since v1:
 + Removed redundant change and change the commit message for more precise in PATCH 2/5.

Nhi Pham (1):
  RedfishPkg: Add missing newline character

Vu Nguyen (4):
  RedfishPkg: Correct variable type to prevent memory corruption
  RedfishPkg: Fix condition checking of error status
  RedfishPkg: Create RestEx child on selected interface
  RedfishPkg: Fix compile issue on Linux

[PATCH V3 1/5] RedfishPkg: Correct variable type to prevent memory corruption

[Minh Nguyen]

From: Vu Nguyen <vunguyen@os.amperecomputing.com>

Id will be casted by CoreOpenProtocol, declare this variable with a
wrong type might result in the corruption of other local variables.

[PATCH V3 2/5] RedfishPkg: Fix condition checking of error status

[Minh Nguyen]

From: Vu Nguyen <vunguyen@os.amperecomputing.com>

This change fixes condition checking of error status, the condition
should be compared with TRUE status to be identical with an error message.

[PATCH V3 3/5] RedfishPkg: Create RestEx child on selected interface

[Minh Nguyen]

From: Vu Nguyen <vunguyen@os.amperecomputing.com>

When a MAC address matching interface is found, a RestEx child will be
created to provide the Redfish communication on that interface.
Currently, It will try to locate all RestEx binding services and choose
the first satisfied instance without taking care about current selected
interface. This might raise an issue on the system with multiple network
devices that the RestEx child was installed on wrong interface.

Hi Abner,

  Yes, me too. I have sent the email to miki.demeter@intel.com for 
checking it.

Ok, because the patch in email always has format problem when apply the patch, plus I can't get the patch from group.io; could you please create a PR on your Github thus I can review patches from there.
Just let me know the PR # after you creating it.

Thanks
Abner

Hi Abner,

  While they're checking this issue, they recommend me to re-send v3 so 
I just sent it, you can also use the PR to review at the same time.

Thanks,

Minh Nguyen.

This doesn't work (changes the meaning) and may possibly break ABI.

What error do you get? What compiler?

C99 flexible array members have been well defined and well supported
for maybe 20 years in GCC (https://godbolt.org/z/9qxKar4f6)

Pedro

Re: [edk2-devel] [PATCH V3 5/5] RedfishPkg: Fix compile issue on Linux

[Michael D Kinney]

I agree that flexible array members are a good way to define this.

The consumer needs to allocate extra space for the flexible array member.

If the size of the device path is known, then the allocation can be the exact size needed.

sizeof(REST_EX_SERVICE_DEVICE_PATH_DATA) + DevicePathSize(DevicePath)

Re: [edk2-devel] [PATCH V3 5/5] RedfishPkg: Fix compile issue on Linux

[Minh Nguyen]

[-- Attachment #1: Type: text/plain, Size: 5069 bytes --]

Hi Pedro,

Firstly, thanks for your comments, let me explain.

- "C99 flexible array members have been well defined and well supported
for maybe 20 years in GCC (https://godbolt.org/z/9qxKar4f6)" => *Yes, I 
agree and there's no**
**comment from my side* *but this is completely different with current 
issue, why? Please see the bellow**
**explanation.*
- When we define the PCD to map with any structure in .dec file, 
BaseTools will gen /*PcdValueInit.c*/.
In this file, there're a lot of using 
"/*__FIELD_SIZE(REST_EX_SERVICE_DEVICE_PATH_DATA, DevicePath);*/"
and this is the definiton of this macro "/*#define __FIELD_SIZE(TYPE, 
Field) (sizeof((TYPE *)0)->Field)*/".
When using 
"/*__STATIC_ASSERT((__FIELD_SIZE(REST_EX_SERVICE_DEVICE_PATH_DATA, 
DevicePath) >= 3) || *//*
*//*(__FIELD_SIZE(REST_EX_SERVICE_DEVICE_PATH_DATA, DevicePath) == 0), 
"Input buffer exceeds the buffer array");*/",
"/*(sizeof((TYPE *)0)->Field*/" will be an error (_*error: invalid 
application of ‘sizeof’ to incomplete type *__*
*__*EFI_DEVICE_PATH_PROTOCOL[]*_) => will cause error on 
"__STATIC_ASSERT" because _Static_assert requires its first parameter
to be a constant expression => the error message when compile this code 
is "_*Line 257 Value {0x03,0x0b,0x25,0x00,0x00,0x1b,*__*
*__*0x21,0xdc,0x35,0xb0,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,*__*
*__*0x00,0x00,0x00,0x00,0x00,0x01,0x7f,0xff,0x04,0x00}:293:19: error: 
expression in static assertion is not an integer*_"

- An other demonstation on other platforms in this behavior: you can 
check at 
*edk2-platforms/Features/Intel/SystemInformation/SmbiosFeaturePkg/SmbiosFeaturePkg.dec*.
/*gSmbiosFeaturePkgTokenSpaceGuid.PcdSmbiosType0BiosInformation|{0x0}|SMBIOS_TABLE_TYPE0|0xD0000001 
{*//*
*//*    <HeaderFiles>*//*
*//*      IndustryStandard/SmBios.h*//*
*//*    <Packages>*//*
*//*      MdePkg/MdePkg.dec*//*
*//*SystemInformation/SmbiosFeaturePkg/SmbiosFeaturePkg.dec*//*
*//*  }*/
/*gSmbiosFeaturePkgTokenSpaceGuid.PcdSmbiosType0BiosInformation.BIOSCharacteristicsExtensionBytes[0]|0x33*//*
*//*gSmbiosFeaturePkgTokenSpaceGuid.PcdSmbiosType0BiosInformation.BIOSCharacteristicsExtensionBytes[1]|0x0F*/
This is the declaration to map PcdSmbiosType0BiosInformation with 
SMBIOS_TABLE_TYPE0 structure and
the declaration of BIOSCharacteristicsExtensionBytes is "*UINT8 
BIOSCharacteristicsExtensionBytes[2];*". If
we remove the number of elements (2) to flexible array, we will see the 
same error like "_*Index of BIOSCharacteristicsExtensionBytes[0]:361:19: 
*__*
*__*error: expression in static assertion is not an integer*_".

=> Conclusion: This is not problem on compiler, it just comes from the 
way BasTools gen PcdValueInit.c
and define macros for this case (map PCD structure to any structure). I 
hope it satisfy your concerns.


Thanks,

Minh Nguyen.

      If we remove the number of elements (2) to flexible array, we will see the same error like

  => CONCLUSION: This is not problem of compiler, it just comes from the way BaseTools gen
/*PcdValueInit.c*/  and definition of macros. I hope above explanation satisfy your concern.

Ok, because the patch in email always has format problem when apply the patch, plus I can't get the patch from group.io; could you please create a PR on your Github thus I can review patches from there.

Just let me know the PR # after you creating it.

Caution: This message originated from an External Source. Use proper

caution when opening attachments, clicking links, or responding.





This patchset adds necessary changes for RedfishPkg to avoid some

unexpected cases and fix compilation.



Changes since v3:

  + Replaced __FUNCTION__ with __func__ to be more C11 compliant.

Changes since v2:

  + Added "Cc:" to maintainers in commit message.

  + Corrected patch format subject prefix.

Changes since v1:

  + Removed redundant change and change the commit message for more

precise in PATCH 2/5.



Nhi Pham (1):

   RedfishPkg: Add missing newline character



Vu Nguyen (4):

   RedfishPkg: Correct variable type to prevent memory corruption

   RedfishPkg: Fix condition checking of error status

   RedfishPkg: Create RestEx child on selected interface

   RedfishPkg: Fix compile issue on Linux
