From 9948b1f7097778fc3fa5027ae7b78c33b86e08a1 Mon Sep 17 00:00:00 2001 From: DamonXue Date: Sat, 7 Jun 2025 20:56:22 +0800 Subject: [PATCH] feat: Implement KMS configuration management and dynamic updates - Added a new KMS configuration subsystem to support dynamic KMS settings. - Introduced a global ConfigManager for managing KMS and general configurations. - Implemented KMS configuration validation and connection testing. - Created REST API endpoints for retrieving and updating KMS configurations. - Enhanced the existing configuration handling to include KMS-specific parameters. - Updated the Cargo.toml to include the new KMS feature. - Added comprehensive tests for KMS configuration management and validation. --- Cargo.lock | 6 +- SSE_KMS_IMPROVEMENTS.md | 154 ++++++++++++++ crates/config/Cargo.toml | 11 + crates/config/src/lib.rs | 3 +- crates/config/src/manager.rs | 321 ++++++++++++++++++++++++++++++ crypto/src/error.rs | 6 + crypto/src/sse.rs | 98 ++++++++- crypto/src/sse_kms.rs | 290 +++++++++++++-------------- ecstore/Cargo.toml | 6 +- ecstore/src/config/com.rs | 70 ++++++- ecstore/src/config/kms.rs | 376 +++++++++++++++++++++++++++++++++++ ecstore/src/config/mod.rs | 3 + ecstore/src/lib.rs | 3 + rustfs/src/admin/handlers.rs | 80 ++++++++ rustfs/src/admin/mod.rs | 30 ++- 15 files changed, 1298 insertions(+), 159 deletions(-) create mode 100644 SSE_KMS_IMPROVEMENTS.md create mode 100644 crates/config/src/manager.rs create mode 100644 ecstore/src/config/kms.rs diff --git a/Cargo.lock b/Cargo.lock index 5cb4283c..333f2f96 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2126,7 +2126,7 @@ dependencies = [ "cfg-if", "chacha20poly1305", "hex", - "http", + "http 1.3.1", "jsonwebtoken", "lazy_static", "pbkdf2", @@ -8124,8 +8124,12 @@ version = "0.0.1" dependencies = [ "config", "const-str", + "once_cell", "serde", "serde_json", + "thiserror 2.0.12", + "tokio", + "tracing", ] [[package]] diff --git a/SSE_KMS_IMPROVEMENTS.md b/SSE_KMS_IMPROVEMENTS.md new file mode 100644 index 00000000..0d5ff1db --- /dev/null +++ b/SSE_KMS_IMPROVEMENTS.md @@ -0,0 +1,154 @@ +# RustFS SSE-KMS 改进实现总结 + +本次改进针对 RustFS 的 SSE-KMS 系统进行了四个主要增强，使其更符合 MinIO 标准并支持动态配置管理。 + +## 实现的改进 + +### 1. 创建 KMS 配置子系统 ✅ + +**实现位置**: `crates/config/src/lib.rs` + +- 创建了统一的配置管理器 `ConfigManager` +- 支持动态 KMS 配置的读取、设置和持久化 +- 提供线程安全的全局配置访问 +- 支持配置验证和错误处理 + +**主要功能**: + +```rust +// 全局配置管理器 +ConfigManager::global().get_kms_config("vault").await +ConfigManager::global().set_kms_config("vault", config).await +ConfigManager::global().validate_all_configs().await +``` + +### 2.
