Add support for RSA 2048 SHA 256 signing and verification encoded in a PI FFS GUIDED Encapsulation Section. The primary use case of this feature is in support of signing and verification of encapsulated FVs for Recovery and Capsule Update, but can potentially be used for signing and verification of any content that can be stored in a PI conformant FFS file. Signing operations are performed from python scripts that wrap OpenSsl command line utilities. Verification operations are performed using the OpenSsl libraries in the CryptoPkg.
The guided encapsulation sections uses the UEFI 2.4 Specification defined GUID called EFI_CERT_TYPE_RSA2048_SHA256_GUID. The data layout for the encapsulation section starts with the UEFI 2.4 Specification defined structure called EFI_CERT_BLOCK_RSA_2048_SHA256 followed immediately by the data. The signing tool included in these patches performs encode/decode operations using this data layout. HashType is set to the UEFI 2.4 Specification defined GUID called EFI_HASH_ALGORITHM_SHA256_GUID.

The verification operations require the use of public key(s). A new PCD called gEfiSecurityPkgTokenSpaceGuid.PcdRsa2048Sha256PublicKeyBuffer is added to the SecurityPkg that supports one or more SHA 256 hashes of the public keys. A SHA 256 hash is performed to minimize the FLASH overhead of storing the public keys. When a verification operation is performed, a SHA 256 hash is performed on EFI_CERT_BLOCK_RSA_2048_SHA256.PublicKey and a check is made to see if that hash matches any of the hashes in the new PCD. It is recommended that this PCD always be configured in the DSC file as storage type of [PcdsDynamixExVpd], so the public keys are stored in a protected read-only region.
While working on this feature, I noticed that the CRC32 signing and verification feature was incomplete. It only supported CRC32 based verification in the DXE Phase, so the attached patches also provide support for CRC32 based verification in the PEI Phase.
I also noticed that the most common method for incorporating guided section extraction libraries was to directly link them to the DXE Core, which is not very flexible. The attached patches also add a generic section extraction PEIM and a generic section extraction DXE driver that can each be linked against one or more section extraction libraries. This provides a platform developer with the option of providing section extraction services with the DXE Core or providing section extraction services with these generic PEIM/DXE Drivers.

In this patch a small application is added to AppPkg, with the following
two goals:
- demonstrate how to use OrderedCollectionLib,
- allow users to test and "fuzz" BaseOrderedCollectionRedBlackTreeLib in
particular, entering API "commands" interactively, or providing them
from a script file.
A shell script is included that generates such an API command script.
Speaking about BaseOrderedCollectionRedBlackTreeLib specifically,
OrderedCollectionTest validates the internal red-black properties of the
tree after each read-write operation by setting the
PcdValidateOrderedCollection feature flag to TRUE.
The OrderedCollectionTest application's debugging environment is strictly
specified in the DSC file, because OrderedCollectionTest is entirely
useless for unit testing without full ASSERT() enablement.
The OrderedCollectionTest application deliberately doesn't follow the edk2
coding style in the following:
- const vs. CONST,
- void vs. VOID,
- assert() vs. ASSERT(),
- calloc() and free() vs. AllocateZeroPool() and FreePool(),
- integer types.
This is because OrderedCollectionTest is a standard C application, not a
UEFI application per se. In particular it relies on stdio. INTN, EFIAPI
and CONST VOID are used only in two places, where we provide the
comparator callbacks to OrderedCollectionLib. Proper range checking is
ensured for integers.
The application takes command input from stdin or a file (if the user
requests it), sends command output to stdout or a file (if the user
requests it), prints debug output to the console (as other AppPkg
applications do when debugging is enabled for them), and prints
diagnostics to stderr (like well behaved standard C programs should).
Input/output selection is implemented manually because the old shell
doesn't support input redirection at all, and because the new shell's
input redirection does not co-operate with fgets() for the time being.

edk2 should have a fast and easy-to-use associative array (a dictionary)
type.
Red-black trees have O(log(n)) worst case time complexity for lookup,
insertion, and deletion (where n is the number of nodes in the tree). They
support minimum and maximum lookup with the same time complexity, hence
red-black trees double as priority queues as well.
Given an iterator to a red-black tree node, getting the next or previous
node (which corresponds to the ordered successor or the predecessor,
respectively, according to the user-defined ordering) is O(log(n)) as
well.
The code reflects the Binary Search Trees and Red-Black Trees chapters of
Introduction to Algorithms, by Cormen, Leiserson, Rivest. One point where
the implementation diverges is the first phase of the Delete() operation.
During that phase, the book's algorithm copies the key and other business
*contents* of the successor node (in case the successor node is affected),
and releases the successor node (instead of the node that the user
requested to delete).
While semantically correct, this would break the above iterator validity
guarantee. This implementation replaces the copying of business contents
between nodes with suitable relinking of nodes, so that all iterators
(except the one whose deletion is being requested) remain valid.
I had written this code originally in approx. 2002. I personally own the
copyright of that version and am hereby relicensing it to Red Hat, under
the BSDL. I had used the original code in a few personal projects since,
for example in the lbzip2-0.x parallel (de)compressor, and now I've ported
the library to edk2. Both during the original implementation and now
during the porting I verified all the cases and their proofs as rigorously
as I could, on paper. (NB, I couldn't find any errors in the 2002 code
now.)
During the porting to edk2, I documented all those cases in code comments
as well (at least half of the source is documentation). These comments are
not blind copies of diagrams from the Algorithms book, nor are they copies
from my original code -- I've done them all fresh now, and I've only
matched the results against the book. Reviewers are invited to sit down
with a pen, some paper, the book, and the code.
The Validate() function verifies the internal red-black properties of the
tree. This function helps with unit testing, and is only invoked when
requested with the PcdValidateOrderedCollection feature flag.
A note about diagrams: edges represented by backslash (\) characters are
often written as "\_", ie. with a following underscore. This is because
line-trailing backslashes are processed very early in compilation (in
translation phase 2), "splicing physical source lines to form logical
source lines". Since the edk2 coding style requires "//" comments for such
documentation, a trailing backslash would splice the next physical line
into the "scope" of the comment. To prevent this, trailing backslashes are
defanged by appending underscores, which should be visually bearable.

This library class provides a set of APIs to manage an ordered collection
of items:
- Init(),
- UnInit(),
- Insert(),
- Delete(),
- IsEmpty(),
- Next(),
- Prev(),
- Min(),
- Max(),
- Find(),
- UserStruct().
There are many ways to implement an ordered collection. Depending on the
frequency of the different actions, different internal implementations may
have different performance, memory overhead, or code size.
Developers can select the library instance for a platform or module in
their DSC files that meets the needs of that platform or module.

This library has one depex of SerialPortPpi. Then, the PEIM linked it has this depex so that it is dispatched after SerialPortPpi is installed. SerialPortPpi notifies the platform initialization done, then serial port will work.

If GUIDED section has AUTH attribute only, DxeCore may wrongly set its AuthenticationStatus to 0 when its matched GUIDED extraction handler is not installed and Auth data is not verified. For this case, the return AuthenticationStatus should be EFI_AUTH_STATUS_NOT_TESTED.

The changes are:
1. Add RVCT ARM build target
2. Add suppression of warnings to get openssl building (1295,550,1293,111,68,177,223,144,513,188)
3. Remove architectures that RVCT cannot build for (IA32, X64, and IPF)
4. Add the -DOPENSSL_NO_MD2 flag to prevent link errors from MD2 references; the comments in the .inf assumes that this flag exists but it wasn’t actually set

When running Enquire.efi, several errors similar to the following are produced:
Maximum exponent = 128
Maximum number = 3.40282347e+38
*** WARNING: Possibly bad output from printf above
expected value around 3.40282347e38, bit pattern:
11111111 11111111 01111111 01111111
sscanf gave -inf, bit pattern:
00000000 00000000 10000000 11111111
difference= inf
Overflow doesn’t seem to generate a trap
The memory allocation tests will also fail, sometimes leaving all available memory consumed.
The correct output in the above example is:
Maximum exponent = 128
Maximum number = 3.40282347e+38
Overflow doesn't seem to generate a trap
The root cause is that all operations on values of Long or ULong type, within the gdtoa library, must be 32-bit operations. A previous change replaced the Long and ULong definitions with INTN and UINTN, respectively. While this is correct for a lot of Linux and NetBSD code, it was not correct for this library.
This fix reverts the definitions of ULong and Long back to 32-bit types.
A descriptive comment has also been added to the U union.
Additional white-space has been added to tidy up the definitions of the word0 and word1 macros.
Verified with Enquire.efi and the ISO/IEC C Library compliance Validation Suite.

Eliminate duplicate GUID definition.
Do explicit data cast.
Use StrnCpy instead of StrCpy.
Update GCC assembly.
