 Subject: [PATCH] Remove paths leading to submodules
 We removed submodules used upstream. However, edk2 build system requires
 such include paths to resolve successfully, regardless of the firmware
 platform being built.

 Subject: BaseTools: do not build BrotliCompress (RH only)
 Notes about the RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] ->
 RHEL-8.5/20210520-e1999b264f1f [edk2-stable202105] rebase:

 Notes about the RHEL-8.2/20190904-37eef91017ad [edk2-stable201908] ->

 - New patch.
 BrotliCompress is not used for building ArmVirtPkg or OvmfPkg platforms.
 It depends on one of the upstream Brotli git submodules that we removed
 earlier in this rebase series. (See patch "remove upstream edk2's Brotli
 submodules (RH only").
 Do not attempt to build BrotliCompress.

 Subject: MdeModulePkg: remove package-private Brotli include path (RH only)
 Notes about the RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] ->
 RHEL-8.5/20210520-e1999b264f1f [edk2-stable202105] rebase:

 Notes about the RHEL-8.2/20190904-37eef91017ad [edk2-stable201908] ->
 RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] rebase:
 - New patch.
 Originating from upstream commit 58802e02c41b
 ("MdeModulePkg/BrotliCustomDecompressLib: Make brotli a submodule",
 2020-04-16), "MdeModulePkg/MdeModulePkg.dec" contains a package-internal
 include path into a Brotli submodule.
 The edk2 build system requires such include paths to resolve successfully,
 regardless of the firmware platform being built. Because
 BrotliCustomDecompressLib is not consumed by any OvmfPkg or ArmVirtPkg
 platforms, and we've removed the submodule earlier in this patch set,
 remove the include path too.

 Upstream prefers short debug messages (sometimes even limited to 80
 characters), but any line length under 512 characters is just unsuitable
 for effective debugging. (For example, config strings in HII routing,
 logged by the platform driver "OvmfPkg/PlatformDxe" on DEBUG_VERBOSE
 level, can be several hundred characters long.) 512 is an empirically good
 value.

 - adapt commit 0bc77c63de03 (code and commit message) to upstream commit
  390b95a49c14 ("MdeModulePkg/TerminalDxe: Refine
  InitializeTerminalConsoleTextMode", 2017-01-10).
 When the console output is multiplexed to several devices by
 ConSplitterDxe, then ConSplitterDxe builds an intersection of text modes
 supported by all console output devices.
 Two notable output devices are provided by:
 (1) MdeModulePkg/Universal/Console/GraphicsConsoleDxe,
 (2) MdeModulePkg/Universal/Console/TerminalDxe.
 GraphicsConsoleDxe supports four modes at most -- see
 InitializeGraphicsConsoleTextMode() and "mGraphicsConsoleModeData":
 (1a) 80x25 (required by the UEFI spec as mode 0),
 (1b) 80x50 (not necessarily supported, but if it is, then the UEFI spec
     requires the driver to provide it as mode 1),
 (1c) 100x31 (corresponding to graphics resolution 800x600, which the UEFI
     spec requires from all plug-in graphics devices),
 (1d) "full screen" resolution, derived form the underlying GOP's
     horizontal and vertical resolutions with division by EFI_GLYPH_WIDTH
     (8) and EFI_GLYPH_HEIGHT (19), respectively.
 The automatic "full screen resolution" makes GraphicsConsoleDxe's
 character console very flexible. However, TerminalDxe (which runs on
 serial ports) only provides the following fixed resolutions -- see
 InitializeTerminalConsoleTextMode() and "mTerminalConsoleModeData":
 (2a) 80x25 (required by the UEFI spec as mode 0),
 (2b) 80x50 (since the character resolution of a serial device cannot be
     interrogated easily, this is added unconditionally as mode 1),
 (2c) 100x31 (since the character resolution of a serial device cannot be
     interrogated easily, this is added unconditionally as mode 2).
 When ConSplitterDxe combines (1) and (2), multiplexing console output to
 both video output and serial terminal, the list of commonly supported text
 modes (ie. the "intersection") comprises:
 (3a) 80x25, unconditionally, from (1a) and (2a),
 (3b) 80x50, if the graphics console provides at least 640x950 pixel
     resolution, from (1b) and (2b)
 (3c) 100x31, if the graphics device is a plug-in one (because in that case
     800x600 is a mandated pixel resolution), from (1c) and (2c).
 Unfortunately, the "full screen resolution" (1d) of the GOP-based text
 console is not available in general.
 Mitigate this problem by extending "mTerminalConsoleModeData" with a
 handful of text resolutions that are derived from widespread maximal pixel
 resolutions. This way TerminalDxe won't cause ConSplitterDxe to filter out
 the most frequent (1d) values from the intersection, and eg. the MODE
 command in the UEFI shell will offer the "best" (ie. full screen)
 resolution too.
 Upstreaming efforts for this patch have been discontinued; it was clear
 from the off-list thread that consensus was impossible to reach.

 Subject: OvmfPkg: allow exclusion of the shell from the firmware image (RH
 only)
 Notes about the RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] ->
 RHEL-8.5/20210520-e1999b264f1f [edk2-stable202105] rebase:
 - No manual / explicit code change is necessary, because the newly
  inherited OvmfPkg/AmdSev platform already has its own BUILD_SHELL
  build-time macro (feature test flag), with default value FALSE -- from
  upstream commit b261a30c900a ("OvmfPkg/AmdSev: add Grub Firmware Volume
  Package", 2020-12-14).
 - Contextual differences from new upstream commits 2d8ca4f90eae ("OvmfPkg:
  enable HttpDynamicCommand", 2020-10-01) and 5ab6a0e1c8e9 ("OvmfPkg:
  introduce VirtioFsDxe", 2020-12-21) have been auto-resolved by
  git-cherry-pick.
 - Remove obsolete commit message tags related to downstream patch
  management: Message-id, Patchwork-id, O-Subject, Acked-by
  (RHBZ#1846481).

 - update the patch against the following upstream commits:
  - 4b888334d234 ("OvmfPkg: Remove EdkShellBinPkg in FDF", 2018-11-19)
  - 277a3958d93a ("OvmfPkg: Don't include TftpDynamicCommand in XCODE5

 Bugzilla: 1147592
 When '-D EXCLUDE_SHELL_FROM_FD' is passed to 'build', exclude the shell
 binary from the firmware image.
 Peter Jones advised us that firmware vendors for physical systems disable
 the memory-mapped, firmware image-contained UEFI shell in
 SecureBoot-enabled builds. The reason being that the memory-mapped shell
 can always load, it may have direct access to various hardware in the
 system, and it can run UEFI shell scripts (which cannot be signed at all).
 Intended use of the new build option:
 - In-tree builds: don't pass '-D EXCLUDE_SHELL_FROM_FD'. The resultant
  firmware image will contain a shell binary, independently of SecureBoot
  enablement, which is flexible for interactive development. (Ie. no
  change for in-tree builds.)
 - RPM builds: pass both '-D SECURE_BOOT_ENABLE' and
  '-D EXCLUDE_SHELL_FROM_FD'. The resultant RPM will provide:
  - OVMF_CODE.fd: SecureBoot-enabled firmware, without builtin UEFI shell,
  - OVMF_VARS.fd: variable store template matching OVMF_CODE.fd,
  - UefiShell.iso: a bootable ISO image with the shell on it as default
    boot loader. The shell binary will load when SecureBoot is turned off,
    and won't load when SecureBoot is turned on (because it is not
    signed).
    UefiShell.iso is the reason we're not excluding the shell from the DSC
    files as well, only the FDF files -- when '-D EXCLUDE_SHELL_FROM_FD'
    is specified, the shell binary needs to be built the same, only it
    will be included in UefiShell.iso.

 Drew has proposed that ARM|AARCH64 platform firmware (especially virtual
 machine firmware) print a reasonably early, simple hello message to the
 serial port, regardless of debug mask settings. This should inform
 interactive users, and provide some rough help in localizing boot
 problems, even with restrictive debug masks.
 If a platform doesn't want this feature, it should stick with the default
 empty string.

 The FixedPcdGetSize() macro expands to an integer constant, therefore an
 optimizing compiler can eliminate the new code, if the platform DSC
 doesn't override the empty string (size=1) default of
 PcdEarlyHelloMessage.

 Subject: CryptoPkg/OpensslLib: list RHEL8-specific OpenSSL files in the INFs
 (RH)
 Notes about the RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] ->
 RHEL-8.5/20210520-e1999b264f1f [edk2-stable202105] rebase:
 - Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1938257
 - Recreate the patch based on downstream commits:
  - 56c4bb81b311 ("CryptoPkg/OpensslLib: list RHEL8-specific OpenSSL files
                  in the INFs (RH)", 2020-06-05),
  - e81751a1c303 ("CryptoPkg/OpensslLib: Upgrade OpenSSL to 1.1.1g",
                  2020-11-23),
  - 3e3fe5e62079 ("redhat: bump OpenSSL dist-git submodule to 1.1.1g+ /
                  RHEL-8.4", 2020-11-23).
  (1) At e81751a1c303, downstream edk2 was in sync with upstream edk2
      consuming OpenSSL 1.1.1g (upstream edk2 commit 8c30327debb2
      ("CryptoPkg/OpensslLib: Upgrade OpenSSL to 1.1.1g", 2020-07-25)).
      Since commit 8c30327debb2, upstream edk2 modified the OpensslLib INF
      files, namely
      - CryptoPkg/Library/OpensslLib/OpensslLib.inf
      - CryptoPkg/Library/OpensslLib/OpensslLibCrypto.inf
      in the following commits only:
      - be01087e0780 ("CryptoPkg/Library: Remove the redundant build
        option", 2020-08-12), which did not affect the source file list at
        all,
      - b5701a4c7a0f ("CryptoPkg: OpensslLib: Use RngLib to generate
        entropy in rand_pool", 2020-09-18), which replaced some of the
        *edk2-specific* "rand_pool_noise" source files with an RngLib
        dependency.
      This means that the list of required, actual OpenSSL source files
      has not changed in upstream edk2 since our downstream edk2 commit
      e81751a1c303.
  (2) At commit 3e3fe5e62079 (the direct child of e81751a1c303),
      downstream edk2's OpenSSL dependency was satisfied with RHEL-8
      OpenSSL at dist-git commit bdd048e929dc ("Two fixes that will be
      shipped in RHEL-8.3.0.z", 2020-10-23).
      Since commit bdd048e929dc, RHEL-8 OpenSSL dist-git advanced
      (fast-forwarded) to commit a75722161d20 ("Update to version 1.1.1k",
      2021-05-25), which is the current head of the rhel-8.5.0 branch.
      (See also <https://bugzilla.redhat.com/show_bug.cgi?id=1938257#c6>.)
      At both dist-git bdd048e929dc and dist-git a75722161d20, I built the
      respective RHEL-8 OpenSSL *source* RPM, and prepped the respective
      source tree, with "rpmbuild -bp". Subsequently I compared the
      prepped source trees recursively.
      - The following files disappeared:
        - 29 backup files created by "patch",
        - the assembly generator perl script called
          "ecp_nistz256-avx2.pl", which is not used during the build.
      - The following new files appeared:
        - 18 files directly or indirectly under the "test" subdirectory,
          which are not used during the build,
        - 5 backup files created by "patch",
        - 2 DCL scripts used when building OpenSSL on OpenVMS.
      This means that the total list of RHEL-8 OpenSSL source files has
      not changed in RHEL-8 OpenSSL dist-git since our downstream edk2
      commit 3e3fe5e62079.
  As a result, copy the "RHEL8-specific OpenSSL file list" sections
  verbatim from the INF files, at downstream commit e81751a1c303. (I used
  the "git checkout -p e81751a1c303 -- Library/OpensslLib/OpensslLib.inf
  CryptoPkg/Library/OpensslLib/OpensslLibCrypto.inf" command.)

 RHEL-8.2/20190904-37eef91017ad [edk2-stable201908] rebase:
 - new patch
 The downstream changes in RHEL8's OpenSSL package, for example in
 "openssl-1.1.1-evp-kdf.patch", introduce new files, and even move some
 preexistent code into those new files. In order to avoid undefined
 references in link editing, we have to list the new files.
 Note: "process_files.pl" is not re-run at this time manually, because
 (a) "process_files.pl" would pollute the file list (and some of the
    auto-generated header files) with RHEL8-specific FIPS artifacts, which
    are explicitly unwanted in edk2,
 (b) The RHEL OpenSSL maintainer, Tomas Mraz, identified this specific set
    of files in <https://bugzilla.redhat.com/show_bug.cgi?id=1749693#c10>,
    and will help with future changes too.

 RH-Bugzilla: 1967747
 RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
 Remove the command to register a file in the shell as the
 initial ramdisk for a UEFI stubbed kernel, to be booted next.
 Note: as further dynamic shell commands might show up upstream,
 we intentionally preserve the empty !ifdef'ry context to ease
 future downstream rebases.

 RH-MergeRequest: 46: OvmfPkg/AmdSevDxe: Shim Reboot workaround (RHEL only)
 RH-Bugzilla: 2218196
 RH-Acked-by: Gerd Hoffmann <None>
 RH-Commit: [1/1] 9bf3bb989e36253aa34bf82ecfe8faa7312e8d22 (osteffen/edk2)
 Add a callback at the end of the Dxe phase that sets the
 "FB_NO_REBOOT" variable under the Shim GUID.
 This is a workaround for a boot loop in case a confidential
 guest that uses shim is booted with a vtpm device present.

 Subject: [PATCH] CryptoPkg/CrtLib: add access/open/read/write/close syscalls
 Needed by rhel downstream openssl patches, they use unix syscalls
 for file access (instead of fopen + friends like the rest of the
 code base).  No actual file access is needed for edk2, so just
 add stubs to make linking work.

 Subject: [PATCH] OvmfPkg/Sec: Setup MTRR early in the boot process.
 RH-Author: Gerd Hoffmann <None>
 RH-MergeRequest: 55: OvmfPkg/Sec: Setup MTRR early in the boot process.
 RH-Jira: RHEL-21704
 RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
 RH-Commit: [1/4] c4061788d34f409944898b48642d610c259161f3 (kraxel.rh/centos-src-edk2)
 Specifically before running lzma uncompress of the main firmware volume.
 This is needed to make sure caching is enabled, otherwise the uncompress
 can be extremely slow.
 Adapt the ASSERTs and MTRR setup in PlatformInitLib to the changes.
 Background:  Depending on virtual machine configuration kvm may uses EPT
 memory types to apply guest MTRR settings.  In case MTRRs are disabled
 kvm will use the uncachable memory type for all mappings.  The
 vmx_get_mt_mask() function in the linux kernel handles this and can be
 found here:
 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/x86/kvm/vmx/vmx.c?h=v6.7.1#n7580
 In most VM configurations kvm uses MTRR_TYPE_WRBACK unconditionally.  In
 case the VM has a mdev device assigned that is not the case though.
 Before commit e8aa4c6546ad ("UefiCpuPkg/ResetVector: Cache Disable
 should not be set by default in CR0") kvm also ended up using
 MTRR_TYPE_WRBACK due to KVM_X86_QUIRK_CD_NW_CLEARED.  After that commit
 kvm evaluates guest mtrr settings, which why setting up MTRRs early is
 important now.

 Subject: [PATCH] NetworkPkg TcpDxe: Fixed system stuck on PXE boot flow in
 iPXE environment
 MIME-Version: 1.0
 Content-Type: text/plain; charset=UTF-8
 Content-Transfer-Encoding: 8bit
 This bug fix is based on the following commit "NetworkPkg TcpDxe: SECURITY PATCH"
 REF: 1904a64
 Issue Description:
 An "Invalid handle" error was detected during runtime when attempting to destroy a child instance of the hashing protocol. The problematic code segment was:
 NetworkPkg\TcpDxe\TcpDriver.c
 Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding, &mHash2ServiceHandle);
 Root Cause Analysis:
 The root cause of the error was the passing of an incorrect parameter type, a pointer to an EFI_HANDLE instead of an EFI_HANDLE itself, to the DestroyChild function. This mismatch resulted in the function receiving an invalid handle.
 Implemented Solution:
 To resolve this issue, the function call was corrected to pass mHash2ServiceHandle directly:
 NetworkPkg\TcpDxe\TcpDriver.c
 Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding, mHash2ServiceHandle);
 This modification ensures the correct handle type is used, effectively rectifying the "Invalid handle" error.
 Verification:
 Testing has been conducted, confirming the efficacy of the fix. Additionally, the BIOS can boot into the OS in an iPXE environment.

 Subject: [PATCH] SecurityPkg/RngDxe: add rng test
 Check whenever RngLib actually returns random numbers, only return
 a non-zero number of Algorithms if that is the case.
 This has the effect that RndDxe loads and installs EFI_RNG_PROTOCOL
 only in case it can actually deliver random numbers.

 Subject: [PATCH] OvmfPkg: wire up RngDxe
 Add OvmfRng include snippets with the random number generator
 configuration for OVMF.  Include RngDxe, build with BaseRngLib,
 so the rdrand instruction is used (if available).
 Also move VirtioRng to the include snippets.
 Use the new include snippets for OVMF builds.
 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

 RH-Commit: [1/1] ab8678b61d171f9c19459e034483437b29037b4b (osteffen/edk2)
 The shim fallback reboot workaround (introduced for SEV-ES) does
 not always work for SEV-SNP, due to a conditional early return.
 Let's just register the workaround earlier in this function to
 fix that.

    EmbeddedPkg/Hob: Integer Overflow in CreateHob()
    REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4166
    Fix integer overflow in various CreateHob instances.
    Fixes: CVE-2022-36765
    The CreateHob() function aligns the requested size to 8
    performing the following operation:
    ```
    HobLength = (UINT16)((HobLength + 0x7) & (~0x7));
    ```
    No checks are performed to ensure this value doesn't
    overflow, and could lead to CreateHob() returning a smaller
    HOB than requested, which could lead to OOB HOB accesses.

    MdeModulePkg/Rng: Add GUID to describe unsafe Rng algorithms
    BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4441
    The EFI_RNG_PROTOCOL can rely on the RngLib. The RngLib has multiple
    implementations, some of them are unsafe (e.g. BaseRngLibTimerLib).
    To allow the RngDxe to detect when such implementation is used,
    a GetRngGuid() function is added in a following patch.
    Prepare GetRngGuid() return values and add a gEdkiiRngAlgorithmUnSafe
    to describe an unsafe implementation, cf. the BaseRngLibTimerLib.

 RH-Commit: [1/1] b65130800090192f47f13d67ff14f902a4f5bfb5 (osteffen/edk2)
 Emit a DEBUG_WARN message if there is not enough flash space left to
 write/update a variable. This condition is currently not logged
 appropriately in all cases, given that full variable store can easily
 render the system unbootable.
 This new message helps identifying this condition.

    To keep the MdePkg self-contained and avoid dependencies on GUIDs
    defined in other packages, the BaseRngLibTimer was moved to the
    MdePkg.
    Add a constructor to warn and request to use the MdeModulePkg

    MdePkg/DxeRngLib: Request raw algorithm instead of default
    The DxeRngLib tries to generate a random number using the 3 NIST
    SP 800-90 compliant DRBG algorithms, i.e. 256-bits CTR, HASH and HMAC.
    If none of the call is successful, the fallback option is the default
    RNG algorithm of the EFI_RNG_PROTOCOL. This default algorithm might
    be an unsafe implementation.
    Try requesting the Raw algorithm before requesting the default one.

    MdePkg: Introduce CcMeasurementProtocol for CC Guest firmware
    BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3625
    CC guest is a Confidential Computing guest. If CC Guest firmware
    supports measurement and an event is created, CC Guest firmware
    is designed to report the event log with the same data structure
    in TCG-Platform-Firmware-Profile specification with
    EFI_TCG2_EVENT_LOG_FORMAT_TCG_2 format.
    The CC Guest firmware supports measurement. It is designed to
    produce EFI_CC_MEASUREMENT_PROTOCOL with new GUID
    EFI_CC_MEASUREMENT_PROTOCOL_GUID to report event log and provides
    hash capability.

    MdePkg/Rng: Add GUID to describe Arm Rndr Rng algorithms
    BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4441
    The EFI_RNG_PROTOCOL can rely on the RngLib. The RngLib has multiple
    implementations, some of them are unsafe (e.g. BaseRngLibTimerLib).
    To allow the RngDxe to detect when such implementation is used,
    a GetRngGuid() function is added in a following patch.
    Prepare GetRngGuid() return values and add a gEfiRngAlgorithmArmRndr
    to describe a Rng algorithm accessed through Arm's RNDR instruction.
    [1] states that the implementation of this algorithm should be
    compliant to NIST SP900-80. The compliance is not guaranteed.

 RH-Commit: [2/2] 0d465ca0ea00598e6826446cd08e890c2ae4bea7 (osteffen/edk2)
 The word "Failed" is used when logging tired Rng algorithms.
 These mostly non-critical messages confused some users.
 Reword it and also add a message confirming eventual success to
 deescalate the importance somewhat.

 RH-Author: Oliver Steffen <osteffen@redhat.com>
 RH-MergeRequest: 67: NetworkPkg/DxeNetLib: adjust PseudoRandom error logging
 RH-Jira: RHEL-45899
 RH-Commit: [1/2] 15135d672cef4310cb29f8a55146f36b2ee1f15d (osteffen/edk2)
 There is a list of allowed rng algorithms, if /one/ of them is not
 supported this is not a problem, only /all/ of them failing is an
 error condition.
 Downgrade the message for a single unsupported algorithm from ERROR to
 VERBOSE.  Add an error message in case we finish the loop without
 finding a supported algorithm.

    CVSS 7.5 : CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
    CWE-835 Loop with Unreachable Exit Condition ('Infinite Loop')

    PixieFail Bug #5
    CVE-2023-45233
    CVSS 7.5 : CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
    CWE-835 Loop with Unreachable Exit Condition ('Infinite Loop')
    Infinite loop when parsing a PadN option in the Destination Options
    header
    Change Overview:
    Most importantly this change corrects the following incorrect math
    and cleans up the code.
    >   // It is a PadN option
    >   //
    > - Offset = (UINT8)(Offset + *(Option + Offset + 1) + 2);
    > + OptDataLen = ((EFI_IP6_OPTION *)(Option + Offset))->Length;
    > + Offset     = IP6_NEXT_OPTION_OFFSET (Offset, OptDataLen);
    > case Ip6OptionSkip:
    > - Offset = (UINT8)(Offset + *(Option + Offset + 1));
    >   OptDataLen = ((EFI_IP6_OPTION *)(Option + Offset))->Length;
    >   Offset     = IP6_NEXT_OPTION_OFFSET (Offset, OptDataLen);
    Additionally, this change also corrects incorrect math where the calling
    function was calculating the HDR EXT optionLen as a uint8 instead of a
    uint16
    > - OptionLen = (UINT8)((*Option + 1) * 8 - 2);
    > + OptionLen = IP6_HDR_EXT_LEN (*Option) -
    IP6_COMBINED_SIZE_OF_NEXT_HDR_AND_LEN;
    Additionally this check adds additional logic to santize the incoming
    data

    NetworkPkg TcpDxe: Fixed system stuck on PXE boot flow in iPXE environment
    This bug fix is based on the following commit "NetworkPkg TcpDxe: SECURITY PATCH"
    REF: 1904a64
    Issue Description:
    An "Invalid handle" error was detected during runtime when attempting to destroy a child instance of the hashing protocol. The problematic code segment was:
    NetworkPkg\TcpDxe\TcpDriver.c
    Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding, &mHash2ServiceHandle);
    Root Cause Analysis:
    The root cause of the error was the passing of an incorrect parameter type, a pointer to an EFI_HANDLE instead of an EFI_HANDLE itself, to the DestroyChild function. This mismatch resulted in the function receiving an invalid handle.
    Implemented Solution:
    To resolve this issue, the function call was corrected to pass mHash2ServiceHandle directly:
    NetworkPkg\TcpDxe\TcpDriver.c
    Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding, mHash2ServiceHandle);
    This modification ensures the correct handle type is used, effectively rectifying the "Invalid handle" error.
    Verification:
    Testing has been conducted, confirming the efficacy of the fix. Additionally, the BIOS can boot into the OS in an iPXE environment.

    CVE-2023-45236
    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N
    CWE-200 Exposure of Sensitive Information to an Unauthorized Actor
    Updates TCP ISN generation to use a cryptographic hash of the
    connection's identifying parameters and a secret key.
    This prevents an attacker from guessing the ISN used for some other
    connection.
    This is follows the guidance in RFC 1948, RFC 6528, and RFC 9293.
    RFC: 9293 Section 3.4.1.  Initial Sequence Number Selection
       A TCP implementation MUST use the above type of "clock" for clock-
       driven selection of initial sequence numbers (MUST-8), and SHOULD
       generate its initial sequence numbers with the expression:
       ISN = M + F(localip, localport, remoteip, remoteport, secretkey)
       where M is the 4 microsecond timer, and F() is a pseudorandom
       function (PRF) of the connection's identifying parameters ("localip,
       localport, remoteip, remoteport") and a secret key ("secretkey")
       (SHLD-1).  F() MUST NOT be computable from the outside (MUST-9), or
       an attacker could still guess at sequence numbers from the ISN used
       for some other connection.  The PRF could be implemented as a
       cryptographic hash of the concatenation of the TCP connection
       parameters and some secret data.  For discussion of the selection of
       a specific hash algorithm and management of the secret key data,
       please see Section 3 of [42].
       For each connection there is a send sequence number and a receive
       sequence number.  The initial send sequence number (ISS) is chosen by
       the data sending TCP peer, and the initial receive sequence number
       (IRS) is learned during the connection-establishing procedure.
       For a connection to be established or initialized, the two TCP peers
       must synchronize on each other's initial sequence numbers.  This is
       done in an exchange of connection-establishing segments carrying a
       control bit called "SYN" (for synchronize) and the initial sequence
       numbers.  As a shorthand, segments carrying the SYN bit are also
       called "SYNs".  Hence, the solution requires a suitable mechanism for
       picking an initial sequence number and a slightly involved handshake
       to exchange the ISNs.

    > + }
    2. Ensures that the amount of data written to the buffer is tracked and
    never exceeds that
    > + //
    > + // Check that the option length is valid.
    > + //
    > + if ((DiscoverLen + OpLen + PXEBC_COMBINED_SIZE_OF_OPT_CODE_AND_LEN)

 Subject: [PATCH 1/2] OvmfPkg/CpuHotplugSmm: delay SMM exit
 RH-Author: Gerd Hoffmann <None>
 RH-MergeRequest: 74: OvmfPkg/CpuHotplugSmm: delay SMM exit
 RH-Jira: RHEL-56974
 RH-Acked-by: Oliver Steffen <osteffen@redhat.com>
 RH-Commit: [1/1] e1fb3f4db68457ec9f59ca5db47606bf4c34e6c5 (kraxel.rh/centos-src-edk2)
 Let APs wait until the BSP has completed the register updates to remove
 the CPU.  This makes sure all APs stay in SMM mode until the CPU
 hot-unplug operation is complete, which in turn makes sure the ACPI lock
 is released only after the CPU hot-unplug operation is complete.
 Some background:  The CPU hotplug SMI is triggered from an ACPI function
 which is protected by an ACPI lock.  The ACPI function is in the ACPI
 tables generated by qemu.

 Subject: [PATCH 15/18] OvmfPkg/VirtNorFlashDxe: ValidateFvHeader: unwritten
 state is EOL too
 RH-Author: Gerd Hoffmann <None>
 RH-MergeRequest: 43: OvmfPkg/VirtNorFlashDxe backport
 RH-Jira: RHEL-17587
 RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
 RH-Commit: [17/20] 37220c700ea816c815e0612031e10b7d466b71a2
 It is possible to find variable entries with State being 0xff, i.e. not
 updated since flash block erase.   This indicates the variable driver
 could not complete the header write while appending a new entry, and
 therefore State was not set to VAR_HEADER_VALID_ONLY.
 This can only happen at the end of the variable list, so treat this as
 additional "end of variable list" condition.

 Subject: [PATCH 13/18] OvmfPkg/VirtNorFlashDxe: add a loop for
 NorFlashWriteBuffer calls.
 RH-Author: Gerd Hoffmann <None>
 RH-MergeRequest: 43: OvmfPkg/VirtNorFlashDxe backport
 RH-Jira: RHEL-17587
 RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
 RH-Commit: [15/20] 72004a196ea61d627ab528573db657dd7db16de2
 Replace the two NorFlashWriteBuffer() calls with a loop containing a
 single NorFlashWriteBuffer() call.
 With the changes in place the code is able to handle updates larger
 than two P30_MAX_BUFFER_SIZE_IN_BYTES blocks, even though the patch
 does not actually change the size limit.
