|

|
||||
//! ILM on SSE-KMS buckets while per-key SSE authorization is enforced (backlog#1582).
|
||||
//!
|
||||
//! Per-key KMS authorization (`RUSTFS_KMS_ENFORCE_SSE_KEY_POLICY=true`) scopes the
|
||||
//! SSE-KMS data path to the requesting principal's `kms:GenerateDataKey` /
|
||||
//! `kms:Decrypt` grants. Internal callers — the lifecycle scanner's expiry deletes
|
||||
//! and the tier transition worker's reads — carry no request principal, and
|
||||
//! `authorize_sse_kms_key` (rustfs/src/storage/sse.rs) exempts a `None` principal
|
||||
//! so background maintenance keeps working on encrypted buckets.
|
||||
//!
|
||||
//! These tests pin that exemption end to end. If enforcement ever starts applying
|
||||
//! to the scanner's internal operations, expiry stops happening on SSE-KMS buckets
|
||||
//! and [`ilm_expiration_on_sse_kms_bucket_under_enforcement`] times out; if it
|
||||
//! starts applying to the transition worker or the read-through path,
|
||||
//! [`ilm_transition_on_sse_kms_bucket_under_enforcement_reads_back`] fails at the
|
||||
//! transition wait or the plaintext round-trip.
|
||||
//!
|
||||
//! The replication half of the same acceptance item lives in
|
||||
//! `crates/e2e_test/src/replication_extension_test.rs`
|
||||
//! (`test_bucket_replication_sse_kms_failure_contract`); ILM had no coverage
|
||||
//! before this file.
|
||||
//!
|
||||
//! Deployment constraint pinned by the transition test's setup: the RustFS warm
|
||||
//! backend forwards the object's stored `x-amz-server-side-encryption*` metadata
|
||||
//! as raw headers on the tier data PUT (`build_transition_put_options` +
|
||||
//! `api_put_object.rs` header mapping), so a RustFS tier target must itself have
|
||||
//! KMS enabled and hold the named key or it rejects every transition upload with
|
||||
//! 400 InvalidRequest. That rejection is independent of the enforcement switch;
|
||||
//! the cold server here therefore runs its own Local KMS with the same key id.
