[edk2-devel] [PATCH v3 0/4] StandaloneMmCore finds drivers in uncompressed inner fv.

["Xu, Wei6" <wei6.xu@intel.com>]

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.
PR: https://github.com/tianocore/edk2/pull/4965

V3:
1. Separate patch per individual issue fix on patch V2.
2. Fix one more issue: Limit FwVol encapsulation section recursion in MmCoreFfsFindMmDriver().
