[edk2] [PATCH] MdePkg/BaseMemoryLib: Fix undefined behavior for left-shift operation

[Hao Wu]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=783

Within function InternalMemSetMem(), for line:
  Value32 = (Value << 24) | (Value << 16) | (Value << 8) | Value;

Expression '(Value << 24)' is possible to bring undefined behavior.
Since 'Value' is of type UINT8 (unsigned char), it will be implicitly
promoted to type 'int' before performing the left-shift operation.

It is possible for '(Value << 24)' to exceed the range of type 'int',
which may bring undefined behavior.

This commit add explicit type cast like:
((UINT32)Value << 24)

to resolve the issue.

Re: [edk2] internal structure of EFI_TLS_CA_CERTIFICATE_VARIABLE

Yes, exactly, EFI_CERT_X509_GUID is the correct SignatureType for the 
CACertificate. SignatureHeaderSize should be set to zero. We do miss the check 
in HttpDxe driver, I'm fine to add back the  SignatureType check in 
TlsConfigCertificate(). So, can you report the Bugzilla for this fixing? Thanks.

I don't think it's necessary to restrict/stand the GUID in the field of 
SignatureOwner for the CA certification (at least for now) since it's only used 
to identify the different venders (i.e, Microsoft) so as to avoid the following 
content check. In the UEFI part, we also didn't check the SignatureOwner for 
the any security consideration. So, I think it's safe to generate a GUID using 
the tool at present.

Thanks,
Jiaxin

[edk2] [Patch V2] BaseTools/BinToPcd: Add support for multiple binary input files

[Michael D Kinney]

From: "Kinney, Michael D" 

https://bugzilla.tianocore.org/show_bug.cgi?id=890

There are use cases where a VOID * PCD needs to be generated from multiple
binary input files.  This can be in the form of an array of fixed size
elements or a set of variable sized elements.

Update BinToPcd to support multiple one or more -i INPUTFILE arguments.
By default, the contents of each binary input file are concatenated in
the order provided.  This supports generating a PCD that is an array of
fixed size elements

Add -x, --xdr flags to BinToPcd  to encodes the PCD using the
Variable-Length Opaque Data of RFC 4506 External Data Representation
Standard (XDR).

https://tools.ietf.org/html/rfc4506
https://tools.ietf.org/html/rfc4506#section-4.10

The data format from RFC 4506 meets the requirements for a PCD that is a
set of variable sized elements in the Variable-Length Opaque Data format.
The overhead of this format is a 32-bit length and 0 to 3 bytes of padding
to align the next element at a 32-bit boundary.

[edk2] [Patch] Vlv2TbltDevicePkg: Remove DxeTcg2PhysicalPresenceLibNull

[Michael D Kinney]

From: "Kinney, Michael D" 

https://bugzilla.tianocore.org/show_bug.cgi?id=908

The following commit that to use Tcg2 instead of TrEE breaks the
build of Vlv2TbltDevicePkg\Library\DxeTcg2PhysicalPresenceLibNull

https://github.com/tianocore/edk2/commit/9461604e1490f73fdbcc8e957dbe75f75c73b027#diff-c85873f3649e35873a11936ace983807

The correct fix is to remove the DxeTcg2PhysicalPresenceLibNull
library instance and update library mappings in DSC files.

[edk2] [Patch 2/2] MdeModulePkg/CapsuleApp: Center bitmap at bottom of screen

[Michael D Kinney]

https://bugzilla.tianocore.org/show_bug.cgi?id=907

When -G option is used to convert a BMP file to a UX capsule,
the bitmap is centered horizontally and placed in the lower
half of the screen below the boot logo.

This matches examples shown in the following pages:

https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/user-experience-for-uefi-firmware-updates
https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/boot-screen-components

Checks are also made to make sure the bitmap provided
fits in the current GOP mode.

It is not usable as ordinary memory, given that you turn it into
'special' memory (with side effects) by turning it into a framebuffer.

So EfiReservedMemory is perfectly appropriate here.

Re: [edk2] How to build EDK2 for X64

[Richardson, Brian]

Benedikt:

Ok, so you’re trying to build DUET for IA32 & x64 architecture. The command 
line looks correct per the README: 
https://github.com/tianocore/edk2/tree/master/DuetPkg

What version of NASM are you using?

Are you building from the latest code (master edk2 branch) or UDK2017 (stable 
branch)?

Did you make any code changes?

Thanks … br

X64 build is well supported. You may have another error in the build config, or 
are trying to build X64 against a target that only supports IA32.

Please provide the complete command line you used for the successful and 
failing builds.

Re: [edk2] internal structure of EFI_TLS_CA_CERTIFICATE_VARIABLE

[Laszlo Ersek]

Thanks! I have two more questions.

The nested loops that parse the signature list in TlsConfigCertificate()
currently ignore the contents of the following fields:
- EFI_SIGNATURE_LIST.SignatureType,
- EFI_SIGNATURE_DATA.SignatureOwner.

I'd like the generator / extractor tool to populate these fields
correctly right from the start, so that it remain compatible with future
features added to edk2.


So, I suggest that the tool set "EFI_SIGNATURE_LIST.SignatureType" to
EFI_CERT_X509_GUID ("This identifies a signature based on a DER-encoded
X.509 certificate"). Because, this is what the current edk2 code assumes
anyway -- in TlsSetCaCertificate(), we have a comment saying

  //
  // DER-encoded binary X.509 certificate or PEM-encoded X.509
  // certificate. Determine whether certificate is from DER encoding, if
  // so, translate it to X509 structure.
  //

(1) Do you agree EFI_CERT_X509_GUID is the right setting for
"EFI_SIGNATURE_LIST.SignatureType" (even though the edk2 code currently
ignores it)?

This would also imply that we set
"EFI_SIGNATURE_LIST.SignatureHeaderSize" to zero, according to the UEFI
spec.


Furthermore, what would you suggest for
"EFI_SIGNATURE_DATA.SignatureOwner"? According to the spec, it is "An
identifier which identifies the agent which added the signature to the
list", so in theory we could just generate any GUID for the tool with
"uuidgen". However, based on past experience, this may not be good
enough; for example, the Secure Boot Logo Test in the Microsoft HCK
expect the SignatureOwner field (on the Microsoft certificates) to be
constant 77FA9ABD-0359-4D32-BD60-28F4E78F784B. In other words, Microsoft
want the SignatureOwner field to stand for the organization that issued
the certificates (i.e., themselves), not for the agent that enrolled the
certificates.

(2) Do you foresee any such restrictions for the
"EFI_SIGNATURE_DATA.SignatureOwner" field in
EFI_TLS_CA_CERTIFICATE_VARIABLE? Or is it safe if we generate a GUID for
the tool with "uuidgen"?

Thanks!

[[Evan Lloyd]] 
The problem with " DynamicAcpiTableDxe" is that the table manager can be used 
for SMBIOS tables and even, should you be so inclined (perverse?) Device Tree.  
The "DynamicTableManager" name relates to the fact that the component generates 
and submits tables (of whatever sort) as opposed to the ConfigurationManager 
component which obtains, collates and provides the Configuration information.

> It makes it clear this this code is specifically for generating ACPI tables at

[[Evan Lloyd]] As noted (and implied by the name), the code is not 
"specifically for generating ACPI tables"

That being said, we'd be happy to change the names if you can suggest something 
clearer.
DynamicTablesDxe might do - the "Manager" part is, as you indicate, pretty 
redundant.
That implies changing ConfigurationManager to something like "DynamicConfig".

Would that strike you as clearer?

Regards,
Evan

I'm backporting this patch to the branch UDK2017 with three extra patches.

3ba3528 ArmPkg/Gic: force GIC driver to run before CPU arch protocol driver
c397d52 ArmPkg/ArmGicDxe: Expose HardwareInterrupt2 protocol
9a73ffd EmbeddedPkg: Introduce HardwareInterrupt2 protocol
29d33ba ArmPkg: Tidy GIC code before changes.

But when I start a VM using the new edk2 binary, it throws below error.

Re: [edk2] [edk2 UsbMassStorageDxe v1 1/1] MdeModulePkg/Usb: Replace macro USB_BOOT_IO_BLOCKS

[Zeng, Star]

Ming,

Basically, I am ok with the change in this patch. There are two comments.

1. Please add more background information about the specific device in the 
commit log. For example, you mentioned " like some virtual CD-ROM from BMC " in 
previous patch.
2. Please make sure building pass with the patch on different tool chains. I 
tried to build with the patch on VS2015, but met building failure like below.
warning C4244: '=': conversion from 'UINT32' to 'UINT16', possible loss of data


Ray,

Do you have other concern?


Thanks,
Star

Subject: [edk2 UsbMassStorageDxe v1 1/1] MdeModulePkg/Usb: Replace macro 
USB_BOOT_IO_BLOCKS

Booting from USB may fail while the macro USB_BOOT_IO_BLOCKS set to 128 because 
the block size of some USB devices are exceeded 512. So,the count blocks to 
transfer should be calculated by block size of the USB devices.

Specification (UEFI Spec 2_7_A Sept 6.pdf) describes EfiReservedMemoryType as

Hence EfiReservedMemoryType is not suitable in this case.  Agree?
