* test(replication): pin missing LWW timestamp header transport
Red-light tests for the replication timestamp three-header contract:
- put_object_headers_carry_replication_timestamp_headers pins that
PutObjectOptions::header() must emit the
x-{rustfs,minio}-source-replication-{tagging,retention,legalhold}-timestamp
headers when the internal timestamps are set (currently missing).
- test_put_opts_from_headers_gates_replication_timestamp_persistence_on_authorization
and test_complete_multipart_opts_persist_replication_timestamps_when_authorized
pin that an authorized replication PUT / multipart complete must persist
the inbound timestamps into the internal metadata keys while unauthorized
requests must not (currently never persisted).
- fake_s3_target journals the three timestamp headers per request
(ReplicationTimestampHeaders on RequestRecord) so sender-side e2e
assertions can observe what a real target receives; self-test included.
* fix(replication): transport and persist LWW timestamps for tag, retention, and legal hold
Active-active conflict resolution for concurrent tag/retention/legal-hold
edits needs the source's per-category modification times on both sides of
the wire; the three AdvancedPutOptions timestamp fields were dead and the
headers were neither sent nor parsed.
- Emit x-{rustfs,minio}-source-replication-{tagging,retention,legalhold}-
timestamp from PutObjectOptions::header(); names and RFC3339 values
interoperate with MinIO (minio-go constants.go, object-api-options.go),
pinned by a header_compat wire-name test.
- Default the three AdvancedPutOptions timestamps to UNIX_EPOCH and skip
epoch values in header(), so "never modified" is not sent as a
modification made now.
- Parse the headers only on authorized replication PUTs and multipart
completes, expose them as Option<OffsetDateTime> on ObjectOptions, and
persist them into the dual-prefix internal metadata keys so the
outbound pass (replication_target_boundary) reads the source's
timestamps instead of the mod_time fallback.
- Record the local tagging timestamp in the PutObjectTagging and
DeleteObjectTagging eval metadata, mirroring the object-lock handlers;
without it the sender only ever had the mod_time fallback to offer.
Receiver-side LWW comparison (keep newer stored category metadata over a
stale inbound copy) is left as a TODO at the parse site.
* fix(replication): load the stored tagging timestamp independently of remaining tags
Review: DeleteObjectTagging persists the tagging-timestamp internal key
but leaves the object tagless, and the outbound mapper only loaded the
key inside the user_tags-nonempty branch — the deletion's LWW timestamp
stayed at the epoch and the header was omitted, so the deletion could
never win conflict resolution on the replica. The stored key is now
loaded unconditionally; the mod_time fallback still applies only while
tags exist (MinIO parity), and a tagless object without the key keeps
the epoch default (no header). Deletion-path regression test added.
* fix(storage): reserve replication transport names at metadata ingest
Second review round: a client PUT of
x-amz-meta-x-rustfs-source-replication-tagging-timestamp materialized
the bare transport key as stored user metadata. The outbound
replication header builder forwards user metadata verbatim on a
server-authorized request, so the receiver would persist the
attacker-chosen value as trusted internal LWW state — and for a
tagless object nothing later overwrites it.
The ingest namespacing guard now reserves the whole
x-rustfs-source- / x-minio-source- families (the new timestamps and
their siblings: source-mtime/-etag/-version-id/-replication-request),
folding forged keys back under x-amz-meta-. Forged-ingress regression
covers both prefixes and a sibling.
* fix(replication): harden timestamp replay
* fix(app): route retention helper through facade

The shared module rustfs_utils::http::object_encryption_keys is the single source of truth for encryption metadata key names, but three call sites still carried their own copies or bare literals: crates/kms/src/service.rs (two private constants plus four bare x-rustfs-encryption-* literals on both the write and read path), rustfs/src/app/select_object.rs (six SELECT_* copies), and rustfs/src/storage/options.rs (two private prefix copies now imported from header_compat). All values are unchanged, so the change is a compiler-verified rename.
The reader-only x-rustfs-internal-server-side-encryption- family gets a named constant with the verified judgment recorded on it: no writer emits these keys anywhere in the repo (the SSE writer persists the MinIO-branded keys verbatim for interop), the two comments claiming the dual-key invariant writes this twin were wrong and are corrected, and the defensive redaction/strip readers are kept because removing them is risk-asymmetric.
rustfs-kms's rustfs-utils dependency now declares the http feature it uses instead of relying on feature unification from sibling crates.
Refs rustfs/backlog#1775, rustfs/backlog#1562.
backlog#1833 PR1 prescribed deduplicating crates/replication/src/http.rs onto the canonical rustfs-utils http modules via a re-export facade. That plan conflicts with a standing architecture guard the issue's review missed: check_architecture_migration_rules.sh rejects any rustfs-utils import or dependency from the replication crate ("replication crate HTTP/helper contracts must not import or depend on rustfs-utils"), the same way it bans rustfs-filemeta and rustfs-storage-api — the wire-contract crate deliberately has zero internal dependencies.
So this lands the issue's fallback shape instead (the same bidirectional do-not-merge pattern the issue itself prescribes for the policy path.rs cluster): a module doc on replication/http.rs naming the canonical owners and the guard that forces the local copy, mirror notes on utils' metadata_compat.rs and header_compat.rs, and a new test pinning every duplicated constant to its literal wire value so the two copies cannot drift silently.
No production code changed.
Ref rustfs/backlog#1833 (PR1).
Groundwork for encrypted-object replication (backlog#1783, PR-A of 3):
- classify_replication_source_encryption: accept the AES256 marker that
every stored SSE-C object carries; the SseC arm was unreachable.
- Fail closed on sealed material without an SSE marker (MinIO-written
objects) instead of replicating ciphertext as plaintext.
- Replace the dead VALID_SSE_REPLICATION_HEADERS table with a transport
map keyed by the metadata keys the SSE writer actually persists, shared
via the new rustfs_utils::http::object_encryption_keys module.
- Structurally strip all encryption metadata from outbound replication
(x-rustfs-encryption-* envelopes previously passed the filters).
- Skip decrypt_checksums for encrypted objects at the boundary so its
is_multipart=false (a response-path contract) cannot misroute
encrypted multipart objects once managed replication opens.
- Redact X-Rustfs-Replication-* SSE transport values in FileInfo Debug.
A reconciliation test pins that every key encryption_material_to_metadata
produces is either transport-mapped or stripped. All four SSE replication
e2e contracts still assert FAILED unchanged.
* refactor(sse): decouple encryption from ecstore
* feat(kms): enhance KMS service manager with runtime state and persistence support
* feat(kms): add local key export functionality for SSE-S3 migration tests
* fix(kms): keep local key export narrowly scoped
* fix(sse): validate copy source customer algorithm
