## 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 (include `Red Hat Test Certifying CA` in `db`).
