[edk2-devel] [PATCH v2 0/1] StandaloneMmCore finds drivers in uncompressed inner fv.
Posted by Xu, Wei6 2 years, 3 months ago 
V1:
This patch is to fix the issue that StandaloneMmCore fails to detect uncompressed inner FV.
PR: https://github.com/tianocore/edk2/pull/4943

V2:
Based on V1, fix some other issues
1. Add Missing object size checks before casting pointers to header types
  a. InnerFvHeader = (EFI_FIRMWARE_VOLUME_HEADER *)SectionData; 
     This is introduced in V1, add the size check on SectionDataSize against EFI_FIRMWARE_VOLUME_HEADER
  b. Section = (EFI_COMMON_SECTION_HEADER *)(FileHeader + 1);
     Use FfsFindSection instead of FfsFindSectionData to avoid pointer casting.
2. Fix potential memory leak issue that ScratchBuffer is not freed when page allocation for DstBuffer fails.

Wei,
Thanks for fixing the 3 issues.
Can you kindly separate the one patch to at least 2 patches?
One patch is to fix minor issues.
The other is to add support of nested uncompressed FV.

Thanks,
Ray

Yes please!

I'd even prefer a separate patch per individual issue fix (especially if
you count the recursion limiting too).

Thanks!
Laszlo

Posted by Xu, Wei6 2 years, 3 months ago 
Hi Laszlo and Ray,

Thanks a lot for the review. Patch V3 is sent out to:
1. Separate patch per individual issue fix
2. Limit FwVol encapsulation section recursion in MmCoreFfsFindMmDriver().
(https://edk2.groups.io/g/devel/message/110296)

Could you please help to review it again? Thanks a lot!

BR,
Wei
