houseme be6859be55 fix(ecstore): handle ChecksumNone in >128 MiB ILM transitions (#4831)
* fix(ecstore): treat ChecksumNone as unset so >128 MiB ILM transitions succeed

ILM transition of any object larger than 128 MiB to a RustFS-native tier
(rustfs/minio/aliyun/tencent/r2/azure/huaweicloud/s3 backends that use the
built-in TransitionClient) failed with "unsupported checksum type", while
objects <=128 MiB transitioned fine.

Root cause: `ChecksumMode::is_set()` reported `ChecksumNone` as a configured
checksum. `ChecksumNone` is the zeroth enum variant, so it occupies bit 0 of
the EnumSet repr and the `len() == 1` check treated "no checksum" as set. The
128 MiB boundary is the warm backend's `MIN_PART_SIZE`, which selects a single
PUT (<=128 MiB) versus a multipart PUT (>128 MiB). On the multipart path,
`put_object_multipart_stream_optional_checksum` saw `checksum.is_set() == true`,
disabled the Content-MD5 branch, and called `ChecksumNone.hasher()`, which
returns the "unsupported checksum type" error. The single-PUT path hit the same
misjudgement but never calls `hasher()`, so it silently succeeded (without a
checksum), which is why only >128 MiB objects failed.

Fix:
- `is_set()` returns false for `ChecksumNone` (and the bare `ChecksumFullObject`
  flag, which has no base algorithm). This is the sole callers' intended
  meaning: a concrete algorithm with a real hasher is selected.
- Defense in depth: guard the multipart checksum branch on
  `auto_checksum.is_set()` so an unset mode uploads the part without a per-part
  checksum header instead of hard-failing in `hasher()`.

Only the TransitionClient consumes this `ChecksumMode::is_set()`; the
server-side data path uses the unrelated `rustfs_rio::ChecksumType`.

Tests: is_set()/set_default semantics, hasher parity for every set mode, and a
`build_transition_put_options` invariant (checksum unset + Content-MD5 on).

* fix(ecstore): read exactly one part per multipart chunk in transition uploads

Second defect behind the >128 MiB ILM transition failure (rustfs/rustfs#4811),
uncovered while verifying the checksum fix.

`put_object_multipart_stream_optional_checksum` read each part with
`read_all()` / `to_vec()`, which drained the entire source into the first part
and left every later part empty. Any multipart upload of a streamed
(`ObjectBody`) source was therefore malformed. Objects <=128 MiB take the
single-part path and were unaffected; a 128 MiB + 1 byte object splits into a
128 MiB part plus a 1 byte part, so the first part received the whole object and
its declared Content-Length (part_size) did not match the body.

Verified empirically: `optimal_part_info(128 MiB + 1, 128 MiB)` yields 2 parts,
and `GetObjectReader::read_all()` on part 1 returns the full 134217729 bytes,
leaving 0 for part 2.

Fix:
- Add `read_multipart_part`, which reads exactly the requested part size (or
  less at EOF) and advances the reader, for both `Body` (in-memory) and
  `ObjectBody` (streamed) sources.
- Upload each part with the bytes actually read (`length`) as its size, and
  account uploaded size by actual bytes, so a short read is detected instead of
  masked.

The concurrent (`put_object_multipart_stream_parallel`) and SigV2
(`put_object_multipart`) paths share the same `read_all()` pattern but are not
exercised by transition; left untouched here and noted for follow-up.

Tests: `read_multipart_part` splits a 250-byte source into [100, 100, 50] for
both streamed and in-memory bodies, consumes the source fully, and stops at EOF
without overrun.

* fix(ecstore): complete the >128 MiB ILM transition multipart client

Docker end-to-end reproduction of rustfs/rustfs#4811 (two RustFS tiers, a
128 MiB + 1 byte object, zero-day transition) surfaced four more defects on the
multipart transition path, each masked by the previous one. With the checksum
and part-splitting fixes in place the transition now failed later and later,
and finally produced a 0-byte object with no error at all. Fixed together:

- initiate_multipart_upload discarded the CreateMultipartUpload response and
  returned an empty UploadId, so the first UploadPart failed with "UploadID
  cannot be empty". Parse the response XML (InitiateMultipartUploadResult now
  derives Deserialize with PascalCase).
- Content-MD5 / x-amz-checksum-* were encoded with URL-safe, unpadded base64,
  which the remote rejected as "Invalid content MD5: Base64Error". Add
  base64_encode_standard and use it for those outbound header values.
- PutObjectOptions::default() set legalhold to OFF, so header() attached
  x-amz-object-lock-legal-hold to every request and CompleteMultipartUpload was
  rejected with "does not accept object lock or governance bypass headers".
  Default to an empty (unset) status.
- CompleteMultipartUpload / CompletePart had no serde renames, so the request
  body used Rust field names (<parts>/<part_num>/<etag>). The remote parsed
  zero <Part> elements and completed a 0-byte object while returning 200. Emit
  S3 element names (<Part>/<PartNumber>/<ETag>) and skip empty checksum fields.

Verified end-to-end: a 128 MiB + 1 byte object now transitions to the remote
tier and reads back (transparently restored) byte-for-byte identical
(sha256 match), with none of the four prior errors in the logs.

Quickstart

To get started with RustFS, follow these steps:

1. One-click Installation (Option 1)

curl -O https://rustfs.com/install_rustfs.sh && bash install_rustfs.sh

2. Docker Quick Start (Option 2)

The RustFS container runs as a non-root user rustfs (UID/GID 10001:10001). If you bind-mount host directories with Docker or Compose, every mounted path must be writable by that user, otherwise startup may fail with permission denied errors. This applies to data directories, log directories, and TLS certificate directories when RUSTFS_TLS_PATH is enabled.

# Create data and logs directories
mkdir -p data logs

# Change the owner of these directories
chown -R 10001:10001 data logs

# Using latest version
docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:latest

# Using specific version
docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:1.0.0-beta.9

If you use podman instead of docker, you can install the RustFS with the below command

# Create data and logs directories
mkdir -p data logs

# Run the container (podman will automatically set the folders ownership)
podman run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data:Z,U -v $(pwd)/logs:/logs:Z,U rustfs/rustfs:latest

If you enable TLS with a bind-mounted certificate directory, prepare that mount the same way:

mkdir -p certs
chown -R 10001:10001 certs

You can also use Docker Compose. Using the docker-compose-simple.yml file in the root directory:

docker compose -f docker-compose-simple.yml up -d

Before running Compose with host bind mounts:

  • Ensure every mounted host path is writable by 10001:10001.
  • If you enable TLS, ensure the certificate mount for /opt/tls is also readable by 10001:10001.
  • If matching host ownership is not practical, run the rustfs service with user: "<host-uid>:<host-gid>" instead.
  • docker-compose-simple.yml includes a volume-permission-helper service for named volumes. docker-compose-simple.yml relies on you to prepare bind-mounted host paths in advance.

Similarly, you can run the command with podman

podman compose -f docker-compose-simple.yml up -d

Webhook notification quick start (Docker):

docker run -d --name rustfs -p 9000:9000 \
  -e RUSTFS_NOTIFY_ENABLE=true \
  -e RUSTFS_NOTIFY_WEBHOOK_ENABLE_PRIMARY=on \
  -e RUSTFS_NOTIFY_WEBHOOK_ENDPOINT_PRIMARY=http://<host-ip>:3020/webhook \
  -e RUSTFS_NOTIFY_WEBHOOK_QUEUE_DIR_PRIMARY=/tmp/rustfs-events \
  rustfs/rustfs:latest

Notes:

  • RUSTFS_NOTIFY_ENABLE=true enables the global notify module switch.
  • For ARN arn:rustfs:sqs::primary:webhook, use instance-scoped env vars with _PRIMARY.
  • If queue dir is omitted, default is /opt/rustfs/events; ensure it is writable by the container runtime user.
  • RUSTFS_NOTIFY_WEBHOOK_SKIP_TLS_VERIFY_PRIMARY defaults to false; enabling it skips webhook TLS certificate verification, allows MITM attacks, and emits a startup warning. Prefer RUSTFS_NOTIFY_WEBHOOK_CLIENT_CA_PRIMARY for private CAs.

NOTE: We recommend reviewing the docker-compose.yml file before running. It defines several services including Grafana, Prometheus, and Jaeger, which are helpful for RustFS observability. If you wish to start Redis or Nginx containers, you can specify the corresponding profiles.

3. Build from Source (Option 3) - Advanced Users

For developers who want to build RustFS Docker images from source with multi-architecture support:

# Build multi-architecture images locally
./docker-buildx.sh --build-arg RELEASE=latest

# Build and push to registry
./docker-buildx.sh --push

# Build specific version
./docker-buildx.sh --release v1.0.0 --push

# Build for custom registry
./docker-buildx.sh --registry your-registry.com --namespace yourname --push

The docker-buildx.sh script supports:

  • Multi-architecture builds: linux/amd64, linux/arm64
  • Automatic version detection: Uses git tags or commit hashes
  • Registry flexibility: Supports Docker Hub, GitHub Container Registry, etc.
  • Build optimization: Includes caching and parallel builds

You can also use Make targets for convenience:

make docker-buildx                    # Build locally
make docker-buildx-push               # Build and push
make docker-buildx-version VERSION=v1.0.0  # Build specific version
make help-docker                      # Show all Docker-related commands

Heads-up (macOS cross-compilation): macOS keeps the default ulimit -n at 256, so cargo zigbuild or ./build-rustfs.sh --platform ... may fail with ProcessFdQuotaExceeded when targeting Linux. The build script attempts to raise the limit automatically, but if you still see the warning, run ulimit -n 4096 (or higher) in your shell before building.

4. Build with Helm Chart (Option 4) - Cloud Native

Follow the instructions in the Helm Chart README to install RustFS on a Kubernetes cluster.

For scanner pacing, cycle budgets, bitrot cadence, lifecycle transition status, and single-node single-disk idle CPU tuning, see Scanner Runtime Controls. For repeatable scanner-pressure validation, see Scanner Benchmark Runbook.

5. Nix Flake (Option 5)

If you have Nix with flakes enabled:

# Run directly without installing
nix run github:rustfs/rustfs

# Build the binary
nix build github:rustfs/rustfs
./result/bin/rustfs --help

# Or from a local checkout
nix build
nix run

6. X-CMD (Option 6)

If you are an x-cmd user:

# Run directly without installing
x rustfs

# Download the binary and install it to the global environment
x env use rustfs
rustfs --help

Accessing RustFS

  1. Access the Console: Open your web browser and navigate to http://localhost:9001 to access the RustFS console.
    • Default credentials: rustfsadmin / rustfsadmin
  2. Create a Bucket: Use the console to create a new bucket for your objects.
  3. Upload Objects: You can upload files directly through the console or use S3-compatible APIs/clients to interact with your RustFS instance.

NOTE: To access the RustFS instance via https, please refer to the TLS Configuration Docs.

OIDC Roles Claim (Microsoft Entra ID)

RustFS supports mapping an OIDC claim containing role values into the existing authorization pipeline. The roles_claim setting is optional: when unset or empty, only the groups claim contributes to authorization (same as older RustFS releases). For Microsoft Entra ID app roles, set roles_claim=roles so both console admin checks and bucket IAM policies can evaluate those roles.

Example environment configuration (opt-in roles claim):

RUSTFS_IDENTITY_OPENID_ENABLE=on
RUSTFS_IDENTITY_OPENID_CONFIG_URL="https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration"
RUSTFS_IDENTITY_OPENID_CLIENT_ID="<client-id>"
RUSTFS_IDENTITY_OPENID_CLIENT_SECRET="<client-secret>"
RUSTFS_IDENTITY_OPENID_SCOPES="openid,profile,email"
RUSTFS_IDENTITY_OPENID_GROUPS_CLAIM="groups"
RUSTFS_IDENTITY_OPENID_ROLES_CLAIM="roles"

Policy condition example (evaluate app roles directly with jwt:roles; when roles_claim is configured, RustFS also merges those values into jwt:groups for backward compatibility with older policies):

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["admin:*"],
      "Resource": ["arn:aws:s3:::*"],
      "Condition": {
        "ForAnyValue:StringEquals": {
          "jwt:roles": ["RustFS.ConsoleAdmin"]
        }
      }
    }
  ]
}
