[edk2] [Patch] UefiCpuPkg/RegisterCpuFeaturesLib: Support combo CPU feature style.
Current code assume only one dependence (before or after) for one
feature. Enhance code logic to support feature has two dependence
(before and after) type.

Re: [edk2] [PATCH v3 6/6] MdeModulePkg/Core: add freed-memory guard feature
Star,
I think the CoreGetMemorySpaceDescriptor() can get the memory capabilities. So
we can remove those hard-coded ones. In addition, since CoreAddRange() doesn't
touch mGcdMemorySpaceMap, CoreAcquireGcdMemoryLock and
CoreReleaseGcdMemoryLock are not necessary to protect CoreAddRange(). I'll
drop them as well.
Regards,
Jian

[edk2] [PATCH 2/4] EmbeddedPkg/DwEmmc: Fix SendCommand parameters
From: "Loh, Tien Hock"
Only send BIT_CMD_CHECK_RESPONSE_CRC if MMC commands needs it.
Fixes parameters to ACMD6 where if CMD is application command, ie. CMD55 is
sent before ACMD6, to do response instead of data transfer.
Added CMD51 handling as CMD51 is a data transfer, and needs BIT_CMD_READ
and BIT_CMD_DATA_EXPECTED to be set.
Updates DwEmmcReceiveResponse to SendCommand only if IsPendingReadCommand
or IsPendingWriteCommand is true.

[edk2] [PATCH 1/4] EmbeddedPkg/DwEmmc: Remove unnecessary MicroSecondDelay
From: "Loh, Tien Hock"
Existing implementation checks for error regardless of if
DWEMMC_INT_CMD_DONE is set, causing the loop check to errors out
even when it shouldn't if the MicroSecondDelay doesn't do long
enough delays. This removes MicroSecondDelay and updates the
function to check for CMD_DONE before doing any error checking.

Subject: [edk2] [PATCH 2/2] ShellPkg-Shell App: Provide fully-qualified path
to shell scripts
Importance: High
Section 3.6.2 of version 2.2 of the shell specification requires that
the first positional argument (i.e. arg 0) of a shell script resolves
to "the full path name of the script itself."
Ensure that the startup script and any scripts launched by the shell
meet this requirement.

Re: [edk2] [PATCH v3 6/6] MdeModulePkg/Core: add freed-memory guard feature
On 2018/10/24 13:26, Jian J Wang wrote:
v3 changes:
a. Merge from #4 and #5 of v2 patch
b. Coding style cleanup
Freed-memory guard is used to detect UAF (Use-After-Free) memory issue
which is illegal access to memory which has been freed. The principle
behind is similar to heap guard feature, that is we'll turn all pool
Since we also regard UAF part of heap guard feature, better to use
"pool/page heap guard feature" instead of "heap guard feature" here.
I quoted a piece of code at below and have question that why it uses
hard code Attribute parameter?

memory allocation to page allocation and mark them to be not-present
once they are freed. The freed memory block will not be added back into
memory pool.
This means that, once a page is allocated and freed, it cannot be
re-allocated. This will bring an issue, which is that there's
risk that memory space will be used out. To address it, the memory
service add logic to put part (at most 64 pages a time) of freed pages
back into page pool, so that the memory service can still have memory
to allocate, when all memory space have been allocated once. This is
called memory promotion. The promoted pages are always from the eldest
pages which haven been freed.
This feature brings another problem is that memory map descriptors will
be increased enormously (200+ -> 2000+). One of change in this patch
is to update MergeMemoryMap() in file PropertiesTable.c to allow merge
freed pages back into the memory map. Now the number can stay at around
510.

This issue is hidden in current code but exposed by introduction
of freed-memory guard feature due to the fact that the feature
will turn all pool allocation to page allocation.
The solution is move the memory allocation in CoreGetMemorySpaceMap()
Use 'moving' instead of 'move'?
and CoreGetIoSpaceMap() to be out of the GCD memory map lock.
Please remove CoreGetIoSpaceMap() as the code does not touch it at all.
Although it's rare, a while-loop is added to make sure that the count
of descriptor of memory map is the same after memory allocation, because
it's executed outside the GCD memory lock.

Re: [edk2] [PATCH v3 2/6] MdeModulePkg: introduce UEFI freed-memory guard bit in HeapGuard PCD
On 2018/10/24 13:26, Jian J Wang wrote: v3 changes: a. split from v2 #1 patch file. b. refine the commit message and title. UAF (Use-After-Free) memory issue is kind of illegal access to memory which has been freed. It can be detected by a new freed-memory guard enforced onto freed memory. BIT4 of following PCD is used to enable the freed-memory guard feature. gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPropertyMask Please note this feature is for debug purpose and should not be enabled Suggest also adding this information into the PCD description.

As far as I can see, "RuntimeCryptLib.inf" (where this file is used) is
only linked into runtime DXE modules -- not SMM modules. That means this
issue is not a security bug, because runtime DXE modules can be
overwritten by the OS anyway. (They reside in normal RAM.) Can you
please confirm?
Nonetheless, it would be nice to explain in the commit message, what
exactly "ReqPages" depends on.
If needed, please file a BZ as well. (I'm not saying it's required, but
you might want to consider it, and reference it in the commit message.)
Thanks

[edk2] [PATCH 2/2] ShellPkg-Shell App: Provide fully-qualified path to shell scripts
Section 3.6.2 of version 2.2 of the shell specification requires that
the first positional argument (i.e. arg 0) of a shell script resolves
to "the full path name of the script itself."
Ensure that the startup script and any scripts launched by the shell
meet this requirement.

[edk2] [Patch V2] BaseTools: Fix the bug for Pcd used in command line's override
V2: remove the not used parameter i
Fix the bug for Pcd used in command line not override the Pcd used
in the [component] driver's sub-section.
Case:
DSC file:
[PcdsFixedAtBuild]
TokenSpaceGuid.PcdTest
[Components]
TestPkg/TestDriver.inf {
TokenSpaceGuid.PcdTest|"b"
}
build command with --pcd TokenSpaceGuid.PcdTest="BB"
Then we found the Pcd value in the AutoGen.c file is incorrect,
because of the incorrect logic that use the pcd in the [component]
section to re-override it.

[edk2] [PATCH] CryptoPkg/BaseCryptLib: Fix potential integer overflow issue.
The LookupFreeMemRegion() in RuntimeMemAllocate.c is used to look-up
free memory region for runtime resource allocation, which was designed
to support runtime authenticated variable service.
The direct offset subtractions in this function may bring possible
integer overflow issue.
This patch is to add the extra parameter checks to remove this possible
overflow risk.

Thanks. > > > > My point is that such a fundamental action that needs to occur while > loading the PE/COFF image should not be hooked into the loader this > way. Based upon our discussion at the Linaro Connect, we investigated leveraging the DXE Image Protection support [1] in Standalone MM (StMM). Amongst other challenges, there is a chicken and egg problem. I will try and explain. DXE Memory protection has dependencies that cannot be fulfilled in StMM. A non-exhaustive list is: 1. Dependency on CPU_ARCH protocol 2. Dependency on Loaded Image patch protocol 3. Dependency on Boot services There is an inherent assumption that this support will never be used in SMM. Furthermore, in StMM, permissions are changed when the StMM drivers are first dispatched. A dependency on a driver to change the permissions is the chicken and egg. So we need a library. One option is to introduce a memory protection library in StMM i.e. a library interface like StandaloneMmImageProtect(). This function will be called from generic code after the PE-COFF loader has loaded and relocated the StMM driver image. However, this support is not required on x86. They will have to include a NULL library implementation. This would be in addition to the NULL PeCoffExtraActionLib they already include through MdePkg.dsc. I am hesitant to take this approach in the absence of a requirement on x86. At the same time, the current approach of leveraging the DebugPeCoffExtraActionLib in ArmPkg does not make sense either. IMO, the better approach would be to add a AArch64 specific StandaloneMmPeCoffExtraActionLib in the StandaloneMmPkg. Memory protection will be implemented in the relocation hook. There will be no impact on x86 or the ArmPkg. If in future there is a requirement to support this feature on x86 as well, then a separate library could be implemented. Please let us know if this sounds reasonable to you. Sughosh will be posting the patches with this approach in a bit to aid the discussion.

[edk2] [Patch] BaseTools: list .nasm include inc files as its dependency
From: zhijufan
.nasm source file may include some header files.
header file should be listed in Makefile as .nasm source file
dependency.
But now, BaseTools doesn't find them and list them in Makefile.
This is a missing, because original ASM file supports it.

For void* type pcd in command line, if its value is string, code should not
convert the void* pcd string in command line to array, otherwise it will make
the pcd value in report not match its real raw value.

Subject: [PATCH V2] BaseTools: Convert "Unicode string" to "byte array" if
value type diff
V2:
Fixed 3 typo.
Use startswith(('L"',"L'")) to check if a string is Unicode string.
Use a set PcdValueTypeSet instead of a list PcdValueTypeList to save memory.
V1:
For the same one VOID* pcd, if the default value type of one SKU is "Unicode
string", the other SKUs are "OtherVOID*"(ASCII string or byte array),Then
convert "Unicode string" to "byte array".

Subject: [PATCH V2] BaseTool: Support different PCDs that refers to the same
EFI variable.
V2:
Make the code of patch both compatible for Python2 and Python3.
V1:
If different PCDs refer to the same EFI variable, then do EFI variable
combination, according to the VariableOffset of different PCDS.

Subject: [PATCH] BaseTools: add ASSERT checker for array buffer in fdf and
command line
For structure PCD in fdf file and command line, 1. use compiler time assert to
check the array index, report error if array index exceeds the array number.
2. use compiler time assert to check the array size, report error if the user
declared size in header file is smaller than the user used in fdf file and
command line.
