Unreleased

Added

  • Added init_raw constructor for types generated by the store! macro.
  • Added FilesystemClient::entry_metadata syscall.
  • Added FilesystemClient::rename syscall.
  • Added serializable flag to StorageAttributes for key agreement.
  • Added virtual platform in virt module.
  • Added methods for creating the client stores to ServiceResources.
  • Implemented unsafe_inject_key for Aes256Cbc, Ed255, X255, P256.
  • Added support for custom backends in backend module.
  • Added optional support for API extensions in serde_extensions module behind the serde-extensions feature.
  • Added types::Path re-export of littlefs2::path::Path.
  • Reduced stack usage of Service::process.

Changed

  • Made StorageAttributes non-exhaustive.
  • Changed KeyStore<P: Platform> to KeyStore<S: Store>.
  • Replaced the client ID with a ClientContext struct.
  • Always trigger syscall in PollClient::request and remove PollClient::syscall.
  • Upgrade the interchange dependency to version 0.3.0 (#99)
    • As a consequence the type pipe::TrussedInterchange becomes a constpipe::TRUSSED_INTERCHANGE
  • Made Request, Reply, Error, Context, CoreContext, Mechanism, KeySerialization, SignatureSerialization, consent::Error, ui::Status non-exhaustive.
  • Made postcard_deserialize, postcard_serialize and postcard_serialize_bytes private.
  • Changed &PathBuf to &Path where possible.
  • Change store implementations to use littlefs2’s DynFilesystem trait instead of being generic over the storage implementation.
  • Add nonce argument to wrap_key and unwrap_key syscalls.
  • Use nonce as IV for Aes256Cbc mechanism.
  • Removed serde::{Deserialize, Serialize} implementations for the API request and reply structs, types::{consent::{Error, Level}, reboot::To, StorageAttributes, KeySerialization, SignatureSerialization}.
  • Improved hex formatting of types::Id:
    • Removed the unused Id::hex.
    • Deprecated Id::hex_path and added Id::legacy_hex_path as a replacement.
    • Added Id::clean_hex_path as an alternative to Id::legacy_hex_path.
    • Changed Id::hex_clean to format zero as "00".
  • Change client and mechanism selection:
    • Put all client traits, requests, replies and implementations behind feature flags.
    • Put all mechanisms behind feature flags.
    • Move CryptoClient::attest into new AttestationClient.
  • Pass endpoints to Service::process instead of storing them in the service.
  • Added support for non-static channels:
    • Added lifetimes to ClientImplementation and ServiceEndpoints.
    • Added the pipe::TrussedChannel type.
  • Refactored the Store trait:
    • Removed the requirement for a static lifetime.
    • Removed the Fs wrapper type.
    • Removed the storage types to return &dyn DynFilesystem instead.
    • Removed the Copy requirement.
    • Removed the unsafe keyword for the Store trait.
  • Removed the unsafe keyword for the Platform trait.
  • Replaced the mechanism RPC traits in service with a single MechanismImpl trait.
  • Made the mechanisms module private. Mechanism implementation can still be accessed via the Mechanism enum.
  • Changed the Aes256Cbc mechanism to use no padding instead of zero padding.
  • Updated dependencies to:
    • cbor-smol 0.5
    • cosey 0.4
    • flexiber 0.2
    • heapless 0.9
    • heapless-bytes 0.5
    • littlefs2 0.7

Fixed

  • Fixed off-by-one error in RandomBytes request.
  • Fixed a race condition when iterating over the filesystem in more than one client (#64).
  • Fixed missing path validation in Filestore that allowed clients to escape their namespace (#65).
  • wrap_key: Don't replace associated data with an empty array

Removed

  • Removed unused items:
    • config: MAX_APPLICATION_NAME_LENGTH, MAX_LABEL_LENGTH, MAX_LONG_DATA_LENGTH, MAX_OBJECT_HANDLES, MAX_PATH_LENGTH
    • types: Attributes, CertificateType DataAttributes, KeyAttributes, Letters, LongData, ObjectType, consent::Urgency
  • Removed the Syscall implementations for Service and the Syscall::try_as_new_client and Syscall::try_new_client methods.
  • Removed TrussedInterchange and TRUSSED_INTERCHANGE from pipe.
  • Removed the clients-? features.
  • Removed the store! macro. Embedded runners should provide their own implementation. Software runners can use virt::StoreConfig to create a virt::Store.
