BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275 An SEV-SNP guest requires that private memory (aka pages mapped encrypted) must be validated before being accessed. The validation process consist of the following sequence: 1) Set the memory encryption attribute in the page table (aka C-bit). Note: If the processor is in non-PAE mode, then all the memory accesses are considered private. 2) Add the memory range as private in the RMP table. This can be performed using the Page State Change VMGEXIT defined in the GHCB specification. 3) Use the PVALIDATE instruction to set the Validated Bit in the RMP table. During the guest creation time, the VMM encrypts the OVMF_CODE.fd using the SEV-SNP firmware provided LAUNCH_UPDATE_DATA command. In addition to encrypting the content, the command also validates the memory region. This allows us to execute the code without going through the validation sequence. During execution, the reset vector need to access some data pages (such as page tables, SevESWorkarea, Sec stack). The data pages are accessed as private memory. The data pages are not part of the OVMF_CODE.fd, so they were not validated during the guest creation. There are two approaches we can take to validate the data pages before the access: a) Enhance the OVMF reset vector code to validate the pages as described above (go through step 2 - 3). OR b) Validate the pages during the guest creation time. The SEV firmware provides a command which can be used by the VMM to validate the pages without affecting the measurement of the launch. Approach #b seems much simpler; it does not require any changes to the OVMF reset vector code. Update the OVMF metadata with the list of regions that must be pre-validated by the VMM before the boot.

Create a change description in the format specified below to use in the source control commit log. #. Your commit message must include your ``Signed-off-by`` signature #. Submit your code to the TianoCore project using the process that the project documents on its web page. If the process is not documented, then submit the code on development email list for the project. #. It is preferred that contributions are submitted using the same copyright license as the base project. When that is not possible, then contributions using the following licenses can be accepted: - BSD (2-clause): http://opensource.org/licenses/BSD-2-Clause - BSD (3-clause): http://opensource.org/licenses/BSD-3-Clause - MIT: http://opensource.org/licenses/MIT - Python-2.0: http://opensource.org/licenses/Python-2.0 - Zlib: http://opensource.org/licenses/Zlib For documentation: - FreeBSD Documentation License https://www.freebsd.org/copyright/freebsd-doc-license.html Contributions of code put into the public domain can also be accepted. Contributions using other licenses might be accepted, but further review will be required. Developer Certificate of Origin ------------------------------- Your change description should use the standard format for a commit message, and must include your ``Signed-off-by`` signature. In order to keep track of who did what, all patches contributed must include a statement that to the best of the contributor's knowledge they have the right to contribute it under the specified license. The test for this is as specified in the `Developer's Certificate of Origin (DCO) 1.1 <https://developercertificate.org/>`__. The contributor certifies compliance by adding a line saying Signed-off-by: Developer Name developer@example.org where ``Developer Name`` is the contributor's real name, and the email address is one the developer is reachable through at the time of contributing. :: Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved. Sample Change Description / Commit Message ------------------------------------------ :: From: Contributor Name <contributor@example.com> Subject: [Repository/Branch PATCH] Pkg-Module: Brief-single-line-summary Full-commit-message Signed-off-by: Contributor Name <contributor@example.com> Notes for sample patch email ```````````````````````````` - The first line of commit message is taken from the email's subject line following ``[Repository/Branch PATCH]``. The remaining portion of the commit message is the email's content. - ``git format-patch`` is one way to create this format Definitions for sample patch email `````````````````````````````````` - ``Repository`` is the identifier of the repository the patch applies. This identifier should only be provided for repositories other than ``edk2``. For example ``edk2-BuildSpecification`` or ``staging``. - ``Branch`` is the identifier of the branch the patch applies. This identifier should only be provided for branches other than ``edk2/master``. For example ``edk2/UDK2015``, ``edk2-BuildSpecification/release/1.27``, or ``staging/edk2-test``. - ``Module`` is a short identifier for the affected code or documentation. For example ``MdePkg``, ``MdeModulePkg/UsbBusDxe``, ``Introduction``, or ``EDK II INF File Format``. - ``Brief-single-line-summary`` is a short summary of the change. - The entire first line should be less than ~70 characters. - ``Full-commit-message`` a verbose multiple line comment describing the change. Each line should be less than ~70 characters. - ``Signed-off-by`` is the contributor's signature identifying them by their real/legal name and their email address. Submodules ---------- Submodule in EDK II is allowed but submodule chain should be avoided as possible as we can. Currently EDK II contains the following submodules - CryptoPkg/Library/OpensslLib/openssl - ArmPkg/Library/ArmSoftFloatLib/berkeley-softfloat-3 - MdeModulePkg/Universal/RegularExpressionDxe/oniguruma - MdeModulePkg/Library/BrotliCustomDecompressLib/brotli - BaseTools/Source/C/BrotliCompress/brotli ArmSoftFloatLib is actually required by OpensslLib. It's inevitable in openssl-1.1.1 (since stable201905) for floating point parameter conversion, but should be dropped once there's no such need in future release of openssl. To get a full, buildable EDK II repository, use following steps of git command .. code-block:: bash git clone https://github.com/tianocore/edk2.git cd edk2 git submodule update --init cd .. If there's update for submodules, use following git commands to get the latest submodules code. .. code-block:: bash cd edk2 git pull git submodule update Note: When cloning submodule repos, '--recursive' option is not recommended. EDK II itself will not use any code/feature from submodules in above submodules. So using '--recursive' adds a dependency on being able to reach servers we do not actually want any code from, as well as needlessly downloading code we will not use. .. =================================================================== ..
