Hauser Zhi a8be876fd9 fix(s3): honor presigned x-amz-meta-* query parameters (#9146)
* fix(s3): honor presigned x-amz-meta-* query parameters

The AWS SDK presigners hoist signable x-amz-* headers into the query
string (smithy moveHeadersToQuery), and AWS S3 accepts the hoisted form
as the header it came from. RustFS read user metadata from headers only,
so a presigned PutObject carrying ?x-amz-meta-user-id=u1 returned 200 and
stored an object with empty metadata (rustfs/rustfs#9142).

Add one shared extractor for user-metadata query parameters and wire it
into every metadata-accepting write path (PutObject including snowball
members, CreateMultipartUpload, CopyObject REPLACE) plus the snowball
extract trigger, instead of normalizing per operation the way the
presigned UploadPart checksum fix did. The stored key form is produced by
the same helper as the header path, so the hoisted and header forms land
on disk identically.

Only a signature-covered query is honored: SigV4 signs the canonical
query string, while SigV2 signs headers plus a fixed subresource list
only, so honoring its query would let a presigned-URL holder add object
properties the presigner never authorized. Keys and values that could not
have arrived as a header are rejected rather than stored, since the read
path turns them into header fields and a control character would fail
every Head/Get of that object.

* refactor(s3): hoist signed x-amz query params at the request boundary

Replace the per-write-path query metadata extractor with one boundary
mechanism: restore the `x-amz-*` request properties the SigV4 presigners
hoist into the query (`@smithy/signature-v4` `moveHeadersToQuery`) as
request headers before s3s routes and deserializes the request.

One hook now covers every reader at once — s3s input parsing,
`extract_metadata_from_mime`, the snowball extract trigger and its
transport-key filter, tagging, storage class, object lock and copy
source — so PutObject, CreateMultipartUpload and CopyObject need no
changes at all. It also replaces repeated query parsing along the write
path with a single pass at the boundary.

An existing header always wins, so the hoist is purely additive and the
unsigned-header guard keeps rejecting anything the signer did not sign;
that guard now also accepts a header whose single value equals a
same-named query parameter, which is what the hoist produces and what
the signature covers.

`query_string_is_signed` rules out SigV2 before it trusts any SigV4
marker. SigV2's string-to-sign covers headers plus a fixed subresource
list rather than arbitrary query parameters, so a SigV2 presigned URL
stays valid after `X-Amz-Algorithm`/`X-Amz-Signature` markers are
appended to it; without this rule a URL holder could turn on
`x-amz-meta-snowball-auto-extract` and have a plain upload untarred
(review of #9146).

* fix(s3): hoist signed query params after s3s signature verification

The request-boundary hoist ran before s3s, so the restored `x-amz-*`
headers reached s3s's own verifier, which rejects any `x-amz-*` header
outside `X-Amz-SignedHeaders` (s3s `ops/signature.rs`,
`reject_unsigned_amz_headers`). A valid presigned PUT with
`SignedHeaders=host` and `?x-amz-meta-user-id=u1` therefore came back
with 403 AccessDenied before any handler ran (review of #9146).

Move the hoist to `authorize_request`, RustFS's shared authorization
entry: s3s has already verified the signature there, and policy
evaluation plus the handler read request properties after it, so the
restored headers reach every operation without ever appearing unsigned
to the verifier. The mechanism is unchanged — one gated, validated pass
over the signature-covered query.

CopyObject's replacement metadata now also reads the headers, because
s3s parsed `input.metadata` before the hoist ran.

The hoist itself and its tests stay in `server::layer`; the tower layer
is gone.

* perf(s3): single-pass signature-aware query hoist in auth

Move the query hoist into `auth.rs`, next to the unsigned-header rules it
is part of, so `storage` no longer reaches into `server` for it. Its
documented contract — which request properties the signature covers, and
why SigV2 must never be widened — now lives with the rule it protects.

Make the hot path allocation-free and single-pass. The caller no longer
clones the query just to satisfy the borrow checker, the function no
longer clones it again, and one `form_urlencoded::parse` pass both
recognizes the presigned-SigV4 marker set and stages the hoistable
parameters. Nothing is validated or applied until the gate passes, so a
request whose query is not signature-covered is never rejected here. A
single ASCII scan skips the whole thing when the query names no `x-amz-`
parameter at all, which is every ordinary `?versionId=`/`?uploadId=`
request and every queryless one.

The duplicate-parameter and header-value checks stay strict; only when
they moved, not how they behave.

* fix(s3): keep verifying a query-carried payload hash after the hoist

The hoist restores `?x-amz-content-sha256=<digest>` as a header, but it
runs after s3s has already built the request body. s3s reads its
payload-hash input from the headers only, so it installs no hash
validator for a digest that arrived in the query, and the restored header
then made `get_content_sha256_with_query` conclude the auth layer was
enforcing it. Neither layer verified the body, so a presigned PUT whose
digest exists only in the query accepted a modified payload (review of
#9146).

The question is not whether a digest header is present but whether the
digest reached the request as a query parameter: that one is always the
storage layer's to verify. A digest sent as a header is still left to the
auth layer, which wraps the body in a hash-validating reader for it, so
no payload is hashed twice.

* fix(auth): limit late query hoisting to user metadata

* refactor(s3): drop the stale payload-hash compensation, scope the pre-filter

Limiting the hoist to `x-amz-meta-*` user metadata means it never
manufactures an `x-amz-content-sha256` header, so the payload-hash
predicate's original signal — a digest header present at handler time is
one s3s is enforcing — is exact again. Restore it and drop the
query-aware form: that change existed only to undo a header the hoist is
no longer allowed to create, and it would have hashed a payload twice
for a presigned request that declared a real digest both in the query and
as a header.

Match the pre-filter to the same scope so a query carrying only a typed
property (`x-amz-tagging`, `x-amz-storage-class`, `versionId`) skips the
parse entirely instead of scanning past it.

* test(access): use explicit imports in the signed-query lock regression

The architecture migration rule requires RustFS storage-owner modules to
name their imports instead of pulling the parent module in wholesale, and
`signed_query_lock_permission_regression` was still on `use super::*`.
Import the two symbols it actually uses and drop the unused one.

* test(access): reference FS through the parent import

The layer dependency guard tracks `use crate::...` edges, and naming
`crate::storage::ecfs::FS` from the signed-query regression looked like a
new `infra -> interface` reverse dependency. `access.rs` already reaches
the same type through `use super::ecfs::FS`, so reuse that import instead
of introducing a second, tracked spelling of an edge the module has
always had. No baseline entry, no new edge.

Quickstart

Important

Pool expansion notice:

  • A single-node single-drive (SNSD) deployment is supported only as a standalone local path. It cannot expand in place or be added as a Pool. To move to a multi-drive topology, create a new deployment and migrate data through S3.
  • Keep an existing multi-drive Pool's endpoints and Erasure Set width unchanged; expand by appending a new Pool. With ellipsis-based expansion, every Pool argument must contain an ellipsis expression and expand to at least two drive endpoints.
  • Single-node multi-drive Pools and multi-node Pools with one drive per node are allowed, subject to valid Erasure Set geometry and EC settings; acceptance does not guarantee host-failure tolerance.

These topology rules follow MinIO, but automatic parity selection differs between the projects. See the Pool layout compatibility and regression tests before expanding a deployment.

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.

Upgrading an existing data volume: some older images ran as root. Replacing the image does not change ownership of mounted files. Before upgrading to a non-root image, stop the instances using the volume, confirm the actual host mount paths and runtime UID/GID, and grant that identity access to all existing data and log directories. For ordinary Docker bind mounts using the default identity, run sudo chown -R 10001:10001 /actual/data /actual/logs on the host. Repeat for each data mount; do not apply this recursively to unrelated shared directories. Kubernetes, NFS, ACLs, and rootless UID mappings may require a different ownership or access-control adjustment.

RustFS checks creation, writing, and deletion of a small temporary file in each data root and fixed internal metadata directories when opening a local disk. A failed check rejects that disk through the existing startup/quorum rules and logs the filesystem error; permission diagnostics include the runtime UID/GID and path owner on Unix. This is not a recursive scan of existing buckets or objects: permissions must also allow access to their contents. RustFS does not change ownership automatically. After migration, verify upload, download, and deletion rather than relying only on a green health endpoint.

# 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:1.0.4

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 \
  -e RUSTFS_OUTBOUND_ALLOW_ORIGINS=http://<host-ip>:3020 \
  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, the official image maps /opt/rustfs/events into the persistent /data volume so it is writable by the runtime user and pending events survive container recreation. Override queue_dir when using another deployment layout.
  • 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.
  • Since 1.0.0-beta.11, webhook endpoints on private or container networks (Docker Compose service names, host.docker.internal, RFC 1918 addresses) are blocked unless their exact scheme://host:port origin is listed in RUSTFS_OUTBOUND_ALLOW_ORIGINS (the origin only, without the path). See Outbound Connection Policy.

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 a single-platform image locally
./docker-buildx.sh -p linux/amd64

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

# Build specific version
./docker-buildx.sh --release 1.0.4 --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=1.0.4  # 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. For drive timeout knobs on slow storage — including the walk stall budget that governs ListObjects on large prefixes — see Drive Timeout Tuning.

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

The flake also exports a NixOS module and the RustFS rc client. Add the module to your system and provide credentials through runtime files (for example, sops-nix or agenix) so secrets are never stored in the Nix store:

imports = [ inputs.rustfs.nixosModules.rustfs ];

services.rustfs = {
  enable = true;
  accessKeyFile = "/run/secrets/rustfs-access-key";
  secretKeyFile = "/run/secrets/rustfs-secret-key";
  volumes = [ "/var/lib/rustfs" ];
};

Install the S3-compatible client with nix profile install github:rustfs/rustfs#rustfs-client (the executable is named rc), or use inputs.rustfs.packages.${pkgs.system}.rustfs-client in a system configuration.

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"]
        }
      }
    }
  ]
}
