efi variable store implementation in rust
Project goals:
- Provide a efi variable store implementation for SVSM.
- Replace the current qemu variable store implementation.
What is there:
- core variable store implementation.
- support for variable locking and variable policies.
- partial support for authenticated variables + secure boot.
- parser for EFI_MM_COMMUNICATE protocol buffers.
- parser for json variable store format used by qemu.
- code to parse and replay EFI_MM_COMMUNICATE protocol traces.
- test cases and test utilities.
What is needed still:
- full support for authenticated variables (needs pkcs7 signature verification).
- support for persistent variables in svsm (needs svsm storage support).
- better documentation.
- more test cases.
Features
-
std: Enables support for the standard library. Used for test cases. -
json: Enables read/write variables from/to JSON format, using serde. Used for test cases. -
sbtest: Enable support for booting test kernel builds in secure boot mode (includeRed Hat Test Certifying CAindb).
