* MdeModulePkg: Update DumpImageRecord() in ImagePropertiesRecordLibTaylor Beebe2023-11-271-0/+9
| | | | | | | | | | | | | | | Update DumpImageRecord() to be DumpImageRecords(), and improve the debug output. The function will output at DEBUG_INFO instead, and the function will be run in DXE and SMM MAT logic when the MAT is installed at EndOfDxe on DEBUG builds.

* MdeModulePkg: Fix MAT Descriptor Count CalculationTaylor Beebe2023-11-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | |4K PAGE|DATA|CODE|DATA|CODE|DATA|4K PAGE| Say the above memory region is currently one memory map descriptor. The above image memory layout example contains two code sections oriented in a way that maximizes the number of descriptors which would be required to describe each section. NOTE: It's unlikely that a data section would ever be between two code sections, but it's still handled by the below formula for correctness. There are two code sections (let's say CodeSegmentMax == 2), three data sections, and two unrelated memory regions flanking the image. The number of required descriptors to describe this layout will be 2 * 2 + 3 == 7. This patch updates the calculations to account for the worst-case scenario.

* MdeModulePkg: Enable forward edge CFI in mem attributes tableArd Biesheuvel2023-04-071-1/+7
| | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4405 The memory attributes table has been extended with a flag that indicates whether or not the OS is permitted to map the EFI runtime code regions with strict enforcement for IBT/BTI landing pad instructions. Given that the PE/COFF spec now defines a DllCharacteristicsEx flag that indicates whether or not a loaded image is compatible with this, we can wire this up to the flag in the memory attributes table, and set it if all loaded runtime image are compatible with it.

| | | | | | | | | | | | | | | | UEFI v2.10 introduces a new flag to the memory attributes table to inform the OS whether or not runtime services code regions were emitted by the compiler with guard instructions for forward edge control flow integrity enforcement.
