* fix(sse): resolve bucket default encryption per request
PUT and the POST-object/extract path resolved a bucket's default
encryption with a hard-coded "no explicit SSE-C" flag, so the default was
layered onto a request that already carried an SSE-C header triple and
then tripped that request's own mutual-exclusion check. Every bucket with
default encryption refused SSE-C single PUTs with 400 InvalidArgument,
while CreateMultipartUpload on the same bucket succeeded because it
resolves SSE elsewhere. Both call sites now derive the flag from the
request headers, as COPY already did.
The bucket default's KMS key id was also inherited independently of the
effective algorithm, so an explicit AES256 request against an aws:kms
default bucket produced a self-contradictory algorithm/key-id pair and
was rejected. The key id is now inherited only when the effective
algorithm is aws:kms, matching the storage-layer resolver.
Refs backlog#2368 B1, B2.
* fix(sse): refuse SSE-KMS without a running KMS service
A write requesting aws:kms on a node with no KMS service fell back to the
node-local SSE-S3 provider: the data key was wrapped with
RUSTFS_SSE_S3_MASTER_KEY while the object metadata still recorded
aws:kms and the requested KMS key id. The stored object claimed a KMS
protection it never had, under a key that was never consulted, and no
signal distinguished it from a genuine SSE-KMS object.
The managed-encryption path now asks the resolved DEK provider whether it
wraps with a node-local master key and refuses SSE-KMS in that case:
InvalidRequest when KMS was never configured, ServiceUnavailable when a
configured service is not running. The check sits after the per-key
authorization gate so an unauthorized caller still receives AccessDenied
whatever the KMS runtime state is, and asks the provider rather than a
parallel availability signal because the provider is what actually wraps
the key. A missing master key no longer answers an SSE-KMS request with
an SSE-S3-worded configuration error.
The SSE-S3 local fallback is unchanged.
Refs backlog#2368 B4.
* fix(ecstore): restore and archive tiers in stored coordinates
Multipart restore addressed the remote tier in plaintext coordinates
while the copy-back reads the stored representation. Each part received a
misaligned slice of the remote object whose length still satisfied the
range, the hash reader and the completion size check, so the restore
reported success and silently replaced the object's bytes. Encrypted and
compressed multipart objects were both affected. Restore now accumulates
stored part sizes, passes the stored length to the hash reader alongside
the plaintext length, and validates against the stored size.
The copy-back digests stored bytes, so its computed MD5 is not the
object's public ETag. Restore now preserves the object ETag on both the
single-part and multipart paths, and gives each restored part its own
recorded part ETag rather than the object-level value.
Transition also handed the tier the object's SSE headers and its
RustFS-wrapped data key as request headers. Any S3 target rejected an
SSE-C archive outright, an SSE-KMS archive asked the target to encrypt a
second time under a key id it does not own, and the wrapped DEK left the
cluster. The archive request now strips every SSE header and encryption
marker with the predicate the replication path already uses; the local
xl.meta keeps all of it, so read-through and restore are unaffected.
Objects restored by an affected release are not detected or repaired
retroactively and must be re-restored from the tier.
Refs backlog#2368 B3, B5; backlog#2369 P7.1.
* fix(rio): lock the v1 nonce layout within a segment
Decrypting a v1 segment tried three historical nonce layouts per frame,
independently for every frame. The last of them exists for streams
written before 1.0.0-alpha.91, which reused a segment's part nonce for
every block in it; because block zero's derived nonce equals that base
nonce, a frame encrypted at index zero authenticated at any position. An
attacker able to rewrite the underlying shards could replay it and have
the forged plaintext returned with 200 and an unchanged length. Shard
integrity uses a keyed-hash-free checksum, which such an attacker can
recompute, so it is not a barrier.
A segment now locks onto whichever layout decoded its first non-zero-index
frame and rejects any later frame needing a different one. That leaves one
residual shape: a stream built purely from repeats of frame zero has no
later frame to disagree. New RUSTFS_ENCRYPTION_LEGACY_NONCE_FALLBACK
(default true, so pre-alpha.91 objects keep decrypting) drops the third
layout entirely when set to false, which closes it. Turning it off refuses
pre-alpha.91 objects, so migrate them first by rewriting in place.
Refs backlog#2369 P2.
* fix(kms): reload a service that failed to start
POST /rustfs/admin/v3/kms/reload short-circuited whenever the persisted
configuration matched the in-memory one byte for byte. A node whose KMS
failed to start keeps that configuration and sits in Error, so the
documented recovery call returned "reloaded successfully" while leaving
the node down. Peers reached the same path through the reload broadcast,
so a cluster that lost Vault during a rolling restart had no working
recovery route other than the node-local start endpoint. Reload now
short-circuits only for a service that is actually running, and otherwise
reconfigures, which starts a service that is not running.
The AWS backend also advertised key-version enumeration through
kms/status, which its own documentation says it cannot do; the capability
and its golden snapshot now say false.
Refs backlog#2369 P1, P7.3.
* docs: record the SSE and KMS changes for 1.0.0
The Unreleased changelog section carried no entry for any encryption work
merged since 1.0.0-rc.5, including three items with operational impact:
the config-secret variable whose absence persists secrets in cleartext
with only a warning, the v2 frame write switch and its rolling-upgrade
constraint, and per-key authorization making a public bucket incompatible
with SSE-KMS objects. Adds those plus this batch, including the SSE-KMS
refusal as a breaking change with both routes out.
Also corrects four places where documentation contradicted the code: the
cleanup register still called encrypted range seek opt-in after its
default flipped, the Helm README claimed vault_mount_path only applies to
Transit while the template also feeds the KV2 mount, the disaster-recovery
drill listed bundle contents for backends whose export is refused with
501, and the Chinese README capability table predated most of the feature
set. Documents the SSE-S3 local master key as a first-class operational
mode with its rotation dead end, and what the v1 frame layout does and
does not authenticate.
Refs backlog#2369 P5.
* fix(kms): classify data-path KMS failures by what the caller can do
Only "key not found" and a backend outage were classified; every other
KMS failure that reached the S3 data path fell through to
500 InternalError with a generic message. A disabled or pending-deletion
key, a denied KMS grant, an encryption-context mismatch, an unsupported
algorithm, a credential or timeout failure, and a capability the
configured backend does not have all looked identical to a server fault.
SDKs therefore applied exponential backoff to configuration errors no
retry can fix, and monitoring counted every one of them against the
server's own error rate.
Unusable-key and request-side failures now answer 400, a denied grant
403, transient backend failures 503, and a missing backend capability
501. Damaged, unreadable, or unknown-format key material keeps its 500:
it is a server-side integrity fault, and existing tests pin it.
The classifier is deliberately separate from the admin lifecycle
mapping, which answers 404 for a missing key because there a key id is
the resource being addressed; on the data path it arrives inside a
request header or a bucket default. Messages either name what the caller
asked for or stay generic, with deployment-side detail left on the error
source the way the storage-IO mapping already does.
Refs backlog#2368 B6.
* fix(kms): track and renew static Vault tokens
Token authentication hard-coded "this token carries no lease", so the
renewal task never started, the remaining-TTL gauge was never published,
and nothing looked wrong. `vault token create` grants a 768-hour TTL by
default, so a cluster that had been healthy for a month turned every KMS
call into a 403 and could not recover without a restart or a
reconfigure. Production configuration validation only rejects the
literal dev-token, so an ordinary expiring token reaches a whole cluster.
The source now reads `auth/token/lookup-self` at login and adopts what
Vault reports. A token with no expiry behaves exactly as before. An
expiring renewable one is picked up by the existing renewal loop and
renewed at half TTL like every other auth method. An expiring
non-renewable one warns with its remaining lifetime and publishes the
gauge, so the fail-closed window is visible before it arrives.
The probe never fails the login: a policy that omits lookup-self, or a
Vault that is briefly unreachable, warns and falls back to exactly the
previous behaviour rather than taking down a deployment that works
today. The scripted Vault test double answers the lookup out of band so
existing scripts keep describing only the protocol under test.
Refs backlog#2369 P3.
* feat(sse): report SSE-C requests that arrive without TLS
An SSE-C request carries the customer's AES key in a request header, so
AWS S3 and MinIO both refuse one that did not arrive over TLS. RustFS
accepted them on any transport: a plaintext hop hands the key to anyone
on the path, and since the object cannot be read without that same key,
the exposure lasts as long as the object does.
Refusing outright is the correct end state but not a safe default to
adopt inside a release window, because the project's own s3-tests and
e2e lanes and most staging deployments speak plain HTTP. This release
reports instead: each such request increments
rustfs_ssec_plaintext_requests_total and logs one warning per process, so
an operator can confirm nothing would break before the default flips.
RUSTFS_SSE_C_REQUIRE_TLS=true opts into the AWS 400 now.
The verdict is per connection rather than per deployment: the layer is
built with whether this listener terminated TLS, and additionally accepts
an https protocol forwarded by a proxy the trusted-proxy configuration
already vetted. It sits beside the rate limiter, after the layer that
makes a forwarded protocol trustworthy and after the request context, so
a rejection can echo the request id.
Refs backlog#2369 P7.2.
* fix(kms): say what a node-local backend means for a cluster
The Local backend keeps key material on each node's own disk and
generates its Argon2id salt per node, so two nodes derive different keys
from the same master_key and an object encrypted on one node cannot be
decrypted on another. Behind a load balancer that surfaces as
intermittent 500s on reads that succeeded moments earlier, with nothing
tying the symptom to the cause: the only signal was a generic
"development, testing and demos only" positioning warning that says
nothing about what actually breaks.
Configuring or reconfiguring Local while the deployment is distributed
now logs a dedicated event and appends the consequence to the configure
response, so the operator who made the change sees it. The product
decision to warn rather than refuse is unchanged.
Refs backlog#2369 P7.4.
* docs: record the remaining SSE and KMS changes for 1.0.0
Adds changelog entries for the KMS data-path status classification, the
Vault static-token lease probe, the SSE-C plaintext-transport report and
its switch, and the node-local backend warning.
Documents two things the backend security guide never stated: that SSE-C
belongs on a secure transport, with the counter and switch to plan the
change around, and that the Local backend cannot be shared by a
multi-node deployment because each node derives different keys from the
same master key.
Refs backlog#2368 B6; backlog#2369 P3, P5, P7.2, P7.4.
* fix(kms): report an unreadable key store as an outage on the S3 path
A backend now distinguishes a key store it could not read from a key
that is genuinely absent, but the S3 boundary collapsed the first one
back onto 500 InternalError through the fallthrough for integrity
faults. The distinction was therefore invisible to the client: a
temporary key-directory outage looked exactly like a permanently damaged
key record, and neither the status nor the metric said the request was
worth retrying.
An unreadable key store joins the retryable class and answers 503, next
to a backend error and a credential failure. Damaged, unreadable or
unknown-format key material keeps its 500.
Refs backlog#2368 B6; builds on rustfs/rustfs#7470.
Add an optional TLS passthrough listener to the Gateway API support. When gatewayApi.listeners.tls.enabled is true, the Gateway gets a TLS listener with tls.mode: Passthrough and a TLSRoute is rendered to the RustFS service so TLS terminates at the backend (end-to-end encryption).
Refs rustfs/rustfs#3862.
* fix(admin): bound IAM import archive expansion
MAX_IAM_IMPORT_SIZE caps the compressed upload at 10 MB, but every member of the
archive was then read with read_to_end into an unbounded Vec. Deflate ratios well
above 100:1 are easy to construct, so a small authorized upload could expand
without limit across the seven members ImportIam reads.
Add a shared expansion budget (MAX_IAM_IMPORT_EXPANDED_SIZE, 10x the compressed
cap) drawn down by every member, and route all seven reads through one helper
that reads a byte past the remaining budget to detect overrun. Sharing the budget
bounds the archive as a whole rather than letting each member spend the full
limit independently.
Covers R03-CAN-024 through R03-CAN-030 plus R04-CAN-077 (backlog #1471) — one
fix rather than seven, since all seven call sites were byte-identical.
* fix(kms): confine local key paths and refuse silent key replacement
Local KMS key identifiers arrive from request input — the `name` tag on CreateKey,
the `keyId` body field or query parameter on DeleteKey — and were joined onto
`key_dir` with no validation. An identifier such as `../../tmp/evil` escaped the
configured directory, making key creation a constrained arbitrary-file write and
`DeleteKey` with `force_immediate` a cross-directory delete.
Validate in `master_key_path` and make it fallible, so every filesystem path in
this backend inherits the guard: decode_stored_key, load_master_key,
save_master_key, create_key and delete_key all derive their paths there. The rule
is containment rather than a character allowlist, so identifiers already in use
keep resolving; only separators, NUL, absolute paths and non-single-component
forms are refused. Note `.` and `..` are contained rather than refused — the
`.key` suffix turns them into the ordinary filenames `..key` and `...key`.
Separately, `LocalKmsBackend::create_key` had no existence check, while the
sibling `KmsClient::create_key` has always had one. Since `save_master_key`
renames over its destination, creating a key under an existing name silently
replaced its material and destroyed the ability to decrypt everything wrapped
under it — and the backend path is the one the admin API uses. It now returns
KeyAlreadyExists, matching StaticKmsBackend.
Covers R03-CAN-072, R03-CAN-073 and R07-CAN-103 (backlog #1475). R03-CAN-073
needed no separate change: delete_key routes both its load and its remove_file
through master_key_path.
* fix(swift): bound SLO manifest reads to the 2 MiB manifest limit
The three Swift SLO handlers that load a stored manifest (handle_slo_get,
handle_slo_get_manifest, handle_slo_delete) read the `<object>.slo-manifest`
object to EOF with AsyncReadExt::read_to_end. That key is predictable and
writable through the ordinary object PUT path, so a tenant can replace the
manifest with an arbitrarily large object and then make the server allocate
its full size on every SLO GET, multipart-manifest=get, or
multipart-manifest=delete request - a memory amplification bounded only by
the stored object size (CWE-400 / CWE-770). The 2 MiB manifest limit that
handle_slo_put enforces was not applied on the read side.
Introduce MAX_SLO_MANIFEST_SIZE (the existing 2 MiB PUT limit, now a named
constant) and a shared read_manifest_bytes helper that reads through a
`take(limit + 1)` and rejects anything larger, so an oversized manifest is
refused instead of being buffered first. All three call sites go through the
helper. handle_slo_put now checks the size before parsing the JSON.
Regression tests: test_read_manifest_bytes_rejects_oversized_manifest and
test_read_manifest_bytes_stops_reading_oversized_manifest (which asserts the
reader is not consumed past the limit), plus a boundary test that a manifest
at exactly 2 MiB is still accepted.
* fix(protocols): authorize every object in FTPS/WebDAV recursive deletes
The FTPS and WebDAV gateways authorized only the container before a
recursive delete and then destroyed everything inside it without a
further check:
- FTPS RMD (and DELE on a bucket path ending in '/') cleared
s3:DeleteBucket, then delete_bucket_recursively listed the bucket and
deleted every object.
- WebDAV DELETE on a bucket did the same via its own
delete_bucket_recursively.
- WebDAV DELETE on a directory cleared s3:DeleteObject for the directory
marker key ("dir/") only, then listed that prefix and deleted every
child under it.
A principal holding s3:DeleteBucket (or s3:DeleteObject on a single
marker key) could therefore erase objects it had no s3:DeleteObject
permission for, and the operation reported success.
Deletion stays recursive - that is the expected behaviour for these
protocols - but each object now clears s3:DeleteObject on its own key
before it is removed, and the enumeration clears s3:ListBucket. A denial
aborts the whole operation with access denied rather than being skipped,
so the caller can never be told the delete succeeded while objects were
left behind or removed without authorization.
The test double gained shared-state cloning, delete_object/delete_bucket
call logs, and list/delete queue helpers so the regression tests can
observe that nothing is deleted once a deny lands.
* fix(server,ecstore): bound TLS handshakes and remote volume RPC waits
Three call sites let an unauthenticated client or a misbehaving peer hold
server resources with no deadline.
TLS listener (R03-CAN-035): process_connection awaited
`acceptor.accept(socket)` with no bound. A client that opens a TCP
connection and never finishes the handshake parks a Tokio task and a socket
forever, and the connection cap (RUSTFS_API_MAX_CONNECTIONS) is unlimited by
default, so nothing else sheds it. The handshake now runs under
accept_tls_with_deadline(), reusing the existing HTTP/1 header-read budget —
the established slow-client bound for the pre-request phase — and the
expiry is recorded through the same log/metric path as a handshake error,
under a new TIMEOUT failure kind.
Remote disk RPCs (R03-CAN-049, R03-CAN-050): list_volumes and delete_volume
passed Duration::ZERO, which execute_with_timeout treats as "no deadline",
so a peer that accepts the request and never answers stalls the coordinator
(and, for delete_volume, the bucket-deletion workflow). Both now pass
get_max_timeout_duration(), matching every sibling method in the file.
Regression tests: a silent TLS peer must be shed by the handshake deadline;
list_volumes/delete_volume against a peer that completes the TCP connect and
then goes silent must fail with DiskError::Timeout instead of hanging.
* fix(security): stop leaking signed headers and bound OIDC/KMS credentials
Three independent hygiene fixes found by the security review.
R03-CAN-018 (crates/signer): try_get_canonical_headers and get_signed_headers
logged the complete header map at DEBUG before signing. Runtime callers pass
session credentials and SSE-C key material through these headers, so anyone
able to raise the log level (or read DEBUG logs) recovered
X-Amz-Security-Token and SSE-C keys verbatim. The statements were debugging
leftovers with no operational value and are deleted rather than redacted.
R03-CAN-014 (crates/iam): the OIDC HTTP adapter buffered provider responses
with an unbounded Response::bytes(), so a configured, compromised or
attacker-pointed IdP endpoint could stream an arbitrarily large or endless
body into memory (the ValidateOidcConfig admin handler lets a ServerInfo
caller choose the endpoint). Responses are now read incrementally and fail
closed past MAX_OIDC_RESPONSE_SIZE, and the already SSRF-hardened client
builder gains request and connect timeouts so a stalled provider cannot pin
the calling task indefinitely.
R07-CAN-105 (helm): the Vault KMS token was serialized into the chart
ConfigMap, exposing it to every subject allowed to get ConfigMaps in the
namespace. It now renders into a dedicated Secret that the Deployment and
StatefulSet consume via envFrom; the Secret is separate from the main
credentials Secret so it also works when secret.existingSecret is set.
Regression tests:
- rustfs-signer: signing_never_logs_signed_header_material
- rustfs-iam: oidc_response_body_past_the_limit_is_rejected,
oidc_response_body_at_the_limit_is_accepted
- scripts/test_helm_templates.sh: KMS token must never render in plaintext
* fix(webdav): enforce body limit, request timeout and connection cap
The configured WebDAV maximum body size was enforced from Content-Length, so a
chunked request declared no length and bypassed it entirely. The configured
request timeout was never applied to the connection at all, and the accept loop
spawned a task per connection with no bound, so an unauthenticated client could
hold resources indefinitely and in unbounded number.
Enforce the limit on bytes actually read rather than the declared length, apply
the configured timeout to the request, and bound accepted connections with a new
RUSTFS_WEBDAV_MAX_CONNECTIONS (default 1024) surfaced in the config report.
Covers R03-CAN-051, R03-CAN-052, R03-CAN-067, R04-CAN-089, R05-CAN-094 and
R05-CAN-097 (backlog #1471, #1474).
* fix(security): stop STS credentials from crossing the parent trust boundary
Two related credential-boundary holes let a short-lived STS credential act
with the full, unrestricted authority of the long-term user it was minted
from.
AddUser (R03-CAN-021, CWE-269/863): should_check_deny_only relaxes the admin
policy check to deny-only when a Console/STS session targets the IAM user it
represents. Nothing then stopped that session from calling AddUser with its
own parent's access key, so the handler wrote an attacker-chosen secret key
and status over the parent's stored Credentials via create_user ->
save_user_identity. A session that expires in minutes became permanent
control of the account. AddUser now rejects any temp or service-account
requester whose resolved parent equals the target access key, resolving the
parent the same way should_check_deny_only does (parent_user field, else the
JWT `parent` claim, since some stores persist the parent only in the token).
FTPS/SFTP/WebDAV password auth (R04-CAN-086, CWE-287/862): these protocols
looked the access key up with check_key, which falls back to the STS account
cache, and then compared only the stored secret. An STS access key plus
secret therefore authenticated with no session token presented and no
session-policy claims applied - the holder got the parent's full permissions.
Password authentication now rejects temporary credentials before the secret
comparison. The discriminator is is_temp() && !is_service_account(), the same
one IamCache::update_user_with_claims uses to route an identity into the STS
cache, so service accounts - which resolve policy from stored IAM state
rather than a client-presented token - keep working over these protocols.
Regression tests cover both predicates and pin the guards to their call
sites so neither can be dropped without a test failure.

* feat(helm): support multiple server pools for capacity expansion
The server already understands multiple pools (RUSTFS_VOLUMES is split on
spaces, one pool expression each; rc admin pool/expand/rebalance/
decommission exist), but the chart could only render a single StatefulSet.
Add an opt-in pools mode:
- pools.enabled=false (default) renders byte-identical output to the
current chart (verified against five values variants)
- pools.list renders one StatefulSet per entry; entries may set
replicaCount (4 or 16) and a storageclass block, everything else is
inherited from the top-level values
- pool 0 keeps the legacy StatefulSet/pod/PVC names and its (immutable)
selector, so existing single-pool deployments can be expanded in place
without renaming or data loss; additional pools render as
<fullname>-poolN with a rustfs.com/pool label in their selector
- RUSTFS_VOLUMES and RUSTFS_SERVER_DOMAINS enumerate every pool
- pod anti-affinity is scoped per pool so pools may share nodes while
each pool still spreads its own pods across distinct nodes
- template validation fails fast on unsupported replicaCount, an empty
pools.list, or pools in standalone mode
- pools are append-only by design (list index = identity), documented in
values.yaml and the README
* fix(helm): truncate pool names DNS-safely, document PDB pool scope
Truncate <fullname>-poolN to 63 chars by shortening the base name rather
than the suffix, so the pool index always survives and two pools of a
max-length release cannot collide. Document that the single
PodDisruptionBudget deliberately spans all pools.
* fix(helm): pool-mode anti-affinity must be preferred, not required
Found by live-testing in-place expansion on a 5-node cluster (4-replica
pool 0 + 4-replica pool 1): with requiredDuringScheduling anti-affinity
the expansion deadlocks in a cycle that cannot self-heal -
1. the not-yet-rolled pool-0 pods still carry the unscoped required
rule and repel every rustfs pod from their nodes, so part of pool 1
stays Pending (no IP, no headless-DNS record);
2. every pod that already has the new RUSTFS_VOLUMES exits fatally on
'failed to lookup address information' for those Pending peers;
3. the StatefulSet rolling update is gated on the crashing pod going
Ready, so the remaining pool-0 pods never roll and keep repelling.
Because StatefulSets assign revisions per ordinal, even a subsequent
template fix cannot rescue a wedged rollout (Pending ordinals are only
recreated with the new template after the higher ordinals go Ready) -
the new pool's StatefulSet has to be recreated. Shipping the soft
affinity from the start avoids the state entirely; expansion was
re-tested end-to-end with it and converges.
Pool-mode rendering only - pools.enabled=false still renders the
existing required anti-affinity byte-identically.
