iceberg: vend table-scoped credentials to clients that ask for delegation (#10777)
* iceberg: vend table-scoped credentials to clients that ask for delegation The catalog recognised X-Iceberg-Access-Delegation: vended-credentials and then deliberately said nothing, because it had nothing to vend: it withheld even the S3 endpoint so the client would keep the credentials it was configured with. That left every engine expecting the catalog to hand out access - Snowflake, Databricks, Trino with vending, any multi-tenant setup - needing static S3 keys distributed out of band. Mint an STS session per request instead, scoped by a session policy to the table's own prefix plus the bucket listing needed to resolve it, and return it in the load response config and storage-credentials. The role to assume is named by -s3.iceberg.credentialRole; its trust policy is what decides whether a caller may assume it, and vending stays off until it is set. A failed mint falls back to the old silence rather than handing back an endpoint the client cannot sign for. * iceberg: keep vended credentials inside the table prefix Review follow-ups on credential vending: Listing was granted on the bucket ARN with no condition, so a credential vended for one table could enumerate every other table's object names. Constrain s3:prefix to the table's own prefix, which the S3 gateway already populates for list requests. A table location carrying * or ? would have gone into the policy's resource pattern unescaped and widened the session to sibling prefixes. Refuse to vend for such a location rather than escaping it; nothing the catalog generates contains those characters. DurationSeconds skipped the 900..43200 bounds the other assume-role paths enforce, so -s3.iceberg.credentialDurationSeconds could ask for a session outside them. The check is now shared by all three entry points. * iceberg: return the vended credentials from buildFileIOConfig itself buildStorageConfig was a second name for what buildFileIOConfig already did; it now returns the storage credentials alongside the properties, and callers that only want the properties drop them. * iceberg: split the vended bucket grants, and refuse a whole-bucket scope The prefix condition sat on a statement that also granted GetBucketLocation and ListBucketMultipartUploads, neither of which carries an s3:prefix to satisfy it, so both were denied for every vended credential. GetBucketLocation moves to its own unconditioned statement. ListBucketMultipartUploads is dropped: Iceberg writers complete and abort by upload id, and granting it either leaks in-flight keys bucket-wide or breaks on the same missing prefix. A table whose location has no prefix - one registered at the bucket root - would have been vended read and write over every other table in the bucket. Refuse, the way a location with wildcards is refused. |

iceberg: add view rename, scan-report and snapshots=refs to the catalog (#10776)
* iceberg: add view rename, scan-report and snapshots=refs to the catalog Three gaps against the REST spec that clients hit in normal use: Views had no rename, though tables did and views are stored the same way, so the move is the same catalog-only pointer move. Tables and views share a namespace directory, so both renames now refuse the other kind instead of moving it. Engines POST a scan or commit report after planning; a 404 there turns into an error line per query. Accept the report and discard it - the catalog keeps no metrics store. LoadTable ignored ?snapshots=refs and always returned the whole snapshot history, which is what clients use the parameter to avoid on long-lived tables. * iceberg: authorize view rename against the view ARN, tighten the metrics endpoint Review follow-ups: The shared rename checked the source against a table ARN whatever the kind, so a policy scoped to a view's own ARN never matched and one written for a table ARN was evaluated for a view. The entry kind now carries the ARN builder. The metrics endpoint truncated a report at 1 MiB and then failed to parse it, answering 400 for a query that had actually succeeded. Read one byte past the limit to tell "fits" from "cut short", and discard an oversized report instead of rejecting it. Empty bodies and reports without a report-type are now rejected, which the REST schema requires. ?snapshots= is defined for LoadTable, so it no longer filters what CreateTable echoes back. |

iceberg: support table rename (#10068)
* s3tables: add RenameTable operation * iceberg: support table rename * iceberg: test table rename * s3tables: keep table data in place on rename rename is catalog-only: drop the source's catalog xattrs in place instead of recursively deleting its directory, which wiped the metadata.json and data files the renamed destination still points at. treat a missing table-metadata xattr as NoSuchTable in GetTable so the soft-deleted source name stops resolving. * s3tables: test rename preserves data make the in-memory filer honor recursive data deletion and seed the source table's metadata/ and data/ children, then assert a rename leaves them intact, the source name resolves to NoSuchTable, and the destination resolves to the preserved location. * iceberg: map rename errors through wrapped manager error * s3tables: authorize rename destination namespace rename moved a table into the destination namespace after only checking the source, letting a source-authorized caller place tables in namespaces they don't control. require CreateTable on the destination namespace and bucket before writing. * s3tables: purge renamed table data on drop * s3tables: test table data dir derivation |

iceberg: support views (#10069)
* s3tables: tag table entries and exclude views from table listings * s3tables: add view CRUD operations * iceberg: support view create, load, exists, drop, and list * iceberg: support view update * iceberg: test view error classification and metadata round-trip * iceberg: pre-check existence and write view metadata only after create * iceberg: map view namespace-not-found to 404 * iceberg: test view create namespace-404 and duplicate no-clobber * s3tables: tag view metadata and entry type atomically CreateView wrote ExtendedKeyMetadata and ExtendedKeyEntryType in two UpdateEntry calls, so a partial failure could leave a view directory untagged. Add setExtendedAttributes to set both in one UpdateEntry. * iceberg: roll back view registration when metadata write fails The metadata file is written after the catalog registers the view. If that write fails, drop the just-created view so it doesn't linger pointing at a missing metadata.json. Reuse the DeleteView path via a shared dropView helper. |

iceberg: support multi-table transaction commit (#10066)
* iceberg: support multi-table transaction commit Add handleCommitTransaction for POST /v1/transactions/commit. Validation is atomic across all table-changes (resolve, load, evaluate every requirement before any write); metadata writes and pointer flips are best-effort with rollback, so this is not crash-atomic. * iceberg: route transactions/commit with and without prefix * iceberg: test transaction commit request decoding * iceberg: restore full prior table state on transaction rollback * iceberg: test transaction rollback restores full prior table state * iceberg: only clean up metadata for rolled-back tables |

iceberg: support namespace property updates (#10052)
* iceberg: support namespace property updates
Add POST /v1/namespaces/{namespace}/properties to the REST catalog. It
applies the request's removals and updates and returns the removed/updated/
missing summary the spec defines. A new UpdateNamespace op on the S3 Tables
manager rewrites the stored namespace properties; AWS S3 Tables namespaces
have no properties, so this is the SeaweedFS-side backing for the catalog.
* iceberg: dedup namespace property removals
A key repeated in removals was deleted on its first occurrence, then
reported as missing on the next — landing in both removed and missing.
Skip keys already processed.
* iceberg: map namespace-update backend errors to REST statuses
UpdateNamespaceProperties returned 500 for every manager failure, masking
the namespace being dropped between read and write, or a denied caller.
Inspect the typed S3TablesError and answer 404/403 accordingly, 500 only
for the rest. Also replaces the GetNamespace not-found string match.
* iceberg: test the namespace-properties conflict path
Cover the 422 returned when a key appears in both removals and updates.
The check runs before any backend call, so it needs no filer.

s3tables: scope management authorization to the caller's identity (#9961)
* s3tables: resolve account-less identities to a distinct principal Static identities with no account block default to the shared admin account, so getAccountID returned "admin" for every such user and the permission checks treated them all as the admin principal. Only keep the admin account when the identity actually carries an admin action; otherwise fall back to the unique identity name. * s3tables: limit the open-by-default fallback to anonymous access The legacy permission path allowed any request that no policy explicitly denied whenever default-allow was on, which is the zero-config default. That let an authenticated identity without table permissions reach table resources owned by others. Restrict the fallback to requests with no identity or the anonymous identity; authenticated callers must pass an explicit action or policy check. Zero-config and anonymous access are unchanged. * s3tables: drop the no-op ListTableBuckets account gate The top-level check passed the principal as its own owner, so it always allowed. Per-bucket filtering in the loop is the real authority; remove the dead gate and the now-unused locals. * s3tables: derive the Iceberg catalog's default-allow from auth state The Iceberg catalog reuses the S3 Tables Manager, which hardcoded default-allow on. Authenticated callers were enforced only because the identity struct happens to propagate into the handler; if it were ever dropped, a secured catalog would fall open. Mirror the S3 port and set the Manager's default-allow from the authenticator, so an authenticated caller is enforced regardless. Shell and admin keep their own trusted Manager. Regression test covers the struct, name-only, and admin paths. * s3tables: drop redundant ACTION_ADMIN string conversion ACTION_ADMIN is an untyped string constant, so the conversion is a no-op. * s3tables: enforce name-only authenticated callers, add trusted bypass defaultAllowFor treated a request with no identity object as anonymous, but the Manager path forwards only the identity name (not the struct). A name-only authenticated caller could therefore be misclassified as anonymous and allowed under the open default. Treat a server-set identity name as authenticated too, and add an explicit trusted flag for the local shell/admin tooling that legitimately bypasses authorization. * s3tables: trim verbose comments |

s3,iceberg: reject .. in URL path vars (#9687)
* s3,iceberg: reject `..`/NUL in URL path vars Both gateway routers use mux.NewRouter().SkipClean(true), so a request like `GET /bucket-A/../evil-bucket/key` survives routing as bucket=bucket-A, object=../evil-bucket/key. The captured key is then joined into a filer path; util.JoinPath / path.Join collapse the `..` server-side and the read lands in evil-bucket. With auth on, IAM still authorizes against bucket-A (the mux var), so policy is evaluated against the wrong target. Add a middleware on the S3 bucket subrouter and the Iceberg REST router that rejects any `.`, `..`, NUL, or — for single-segment slots — embedded slash in the captured path vars before any handler runs. NormalizeObjectKey already folds `\` to `/` and decoding happens in mux, so `%2e%2e` and `..\` are caught. * s3,iceberg: reject empty captured vars and empty namespace parts Comma-ok the var lookup so we only check captured slots, then treat an empty captured value as a rejection on its own — downstream path.Join would otherwise collapse it and let the next segment pick the bucket. For iceberg, also reject empty parts after splitting the namespace on \x1F so leading/trailing/consecutive unit separators (which parseNamespace silently folds out) don't let distinct route values collapse to the same parsed namespace. Register loggingMiddleware before validateRequestPath on the iceberg router so rejected requests still produce an audit-log line. |

fix(iceberg): route catalog clients to the right bucket and vend S3 endpoint (#9109)
* fix(iceberg): route catalog clients to the right bucket and vend S3 endpoint DuckDB ATTACH 's3://<bucket>/' AS cat (TYPE 'ICEBERG', ...) was failing with "schema does not exist" because GET /v1/config ignored the warehouse query parameter and returned no overrides.prefix, so subsequent requests fell through to the hard-coded "warehouse" default bucket instead of the one the client attached. LoadTable also returned an empty config, forcing clients to discover the S3 endpoint out-of-band and producing 403s on direct iceberg_scan calls. - handleConfig now echoes overrides.prefix = bucket and defaults.warehouse when ?warehouse=s3://<bucket>/ is supplied. - getBucketFromPrefix honors a warehouse query parameter as a fallback for clients that skip the /v1/config handshake. - LoadTable responses advertise s3.endpoint and s3.path-style-access so clients can reach data files without separate configuration. Refs #9103 * address review feedback on iceberg S3 endpoint vending - deriveS3AdvertisedEndpoint is now a method on S3Options; honors externalUrl / S3_EXTERNAL_URL, switches to https when -s3.key.file is set, uses the https port when configured, and brackets IPv6 literals via util.JoinHostPort. - handleCreateTable returns s.buildFileIOConfig() in both its staged and final LoadTableResult branches so create and load flows see the same FileIO hints. - Add unit test coverage for the endpoint derivation scenarios. * address CI and review feedback for #9109 - DuckDB integration test now runs under its own newOAuthTestEnv (with a valid IAM config) so the OAuth2 client_credentials flow DuckDB requires actually works; the shared env has no registered credentials, which was the cause of the CI failure. Helper createTableWithToken was added to create tables via Bearer auth. - Tighten TestIssue9103_LoadTableDoesNotVendS3FileIOCredentials to also assert s3.path-style-access = "true", so a partial regression where the endpoint is vended but path-style is dropped still fails. - deriveS3AdvertisedEndpoint now logs a startup hint when it infers the host from os.Hostname because the bind IP is a wildcard, pointing operators at -s3.externalUrl / S3_EXTERNAL_URL for reverse-proxy deployments where the inferred name is not externally reachable. - handleConfig has a comment explaining that any sub-path in the warehouse URL is dropped because catalog routing is bucket-scoped. * fix(iceberg): make advertised S3 endpoint strictly opt-in; add region The wildcard-bind fallback to os.Hostname() in deriveS3AdvertisedEndpoint was hijacking correctly-configured clients: on the CI runner it produced http://runnervmrc6n4:<port>, which Spark (running in Docker) could not resolve, so Spark iceberg tests began failing after the endpoint started being vended in LoadTable responses. Change the rule so advertising is opt-in and never guesses a host that might not be routable: - -s3.externalUrl / S3_EXTERNAL_URL wins (covers reverse-proxy). - Otherwise, only an explicit, non-wildcard -s3.bindIp is used. - Wildcard / empty bind returns "" so no FileIO endpoint is vended and existing clients keep using their own configuration. buildFileIOConfig additionally vends s3.region (defaulting to the same value baked into table bucket ARNs) whenever it vends an endpoint, so DuckDB's attach does not fail with "No region was provided via the vended credentials" when the operator has opted in. The DuckDB issue-9103 integration test runs under an env with a wildcard bind, so it explicitly sets AWS_REGION in the docker run to pick up the same default. The HTTP-level LoadTable-vending test was dropped because its expectation is now conditional and already covered by unit tests in iceberg_issue_9103_test.go. |

feat(iceberg): add OAuth2 token endpoint for DuckDB compatibility (#9017)
* feat(iceberg): add OAuth2 token endpoint for DuckDB compatibility (#9015) DuckDB's Iceberg connector uses OAuth2 client_credentials flow, hitting POST /v1/oauth/tokens which was not implemented, returning 404. Add the OAuth2 token endpoint that accepts S3 access key / secret key as client_id / client_secret, validates them against IAM, and returns a signed JWT bearer token. The Auth middleware now accepts Bearer tokens in addition to S3 signature auth. * fix(test): use weed shell for table bucket creation with IAM enabled The S3 Tables REST API requires SigV4 auth when IAM is configured. Use weed shell (which bypasses S3 auth) to create table buckets, matching the pattern used by the Trino integration tests. * address review feedback: access key in JWT, full identity in Bearer auth - Include AccessKey in JWT claims so token verification uses the exact credential that signed the token (no ambiguity with multi-key identities) - Return full Identity object from Bearer auth so downstream IAM/policy code sees an authenticated request, not anonymous - Replace GetSecretKeyForIdentity with GetCredentialByAccessKey for unambiguous credential lookup - DuckDB test now tries the full SQL script first (CREATE SECRET + catalog access), falling back to simple CREATE SECRET if needed - Tighten bearer auth test assertion to only accept 200/500 Addresses review comments from coderabbitai and gemini-code-assist. * security: use PostFormValue, bind signing key to access key, fix port conflict - Use r.PostFormValue instead of r.FormValue to prevent credentials from leaking via query string into logs and caches - Reject client_secret in URL query parameters explicitly - Include access key in HMAC signing key derivation to prevent cross-credential token forgery when secrets happen to match - Allocate dedicated webdav port in OAuth test env to avoid port collision with the shared TestMain cluster |

S3: Implement IAM defaults and STS signing key fallback (#8348)
* S3: Implement IAM defaults and STS signing key fallback logic * S3: Refactor startup order to init SSE-S3 key manager before IAM * S3: Derive STS signing key from KEK using HKDF for security isolation * S3: Document STS signing key fallback in security.toml * fix(s3api): refine anonymous access logic and secure-by-default behavior - Initialize anonymous identity by default in `NewIdentityAccessManagement` to prevent nil pointer exceptions. - Ensure `ReplaceS3ApiConfiguration` preserves the anonymous identity if not present in the new configuration. - Update `NewIdentityAccessManagement` signature to accept `filerClient`. - In legacy mode (no policy engine), anonymous defaults to Deny (no actions), preserving secure-by-default behavior. - Use specific `LookupAnonymous` method instead of generic map lookup. - Update tests to accommodate signature changes and verify improved anonymous handling. * feat(s3api): make IAM configuration optional - Start S3 API server without a configuration file if `EnableIam` option is set. - Default to `Allow` effect for policy engine when no configuration is provided (Zero-Config mode). - Handle empty configuration path gracefully in `loadIAMManagerFromConfig`. - Add integration test `iam_optional_test.go` to verify empty config behavior. * fix(iamapi): fix signature mismatch in NewIdentityAccessManagementWithStore * fix(iamapi): properly initialize FilerClient instead of passing nil * fix(iamapi): properly initialize filer client for IAM management - Instead of passing `nil`, construct a `wdclient.FilerClient` using the provided `Filers` addresses. - Ensure `NewIdentityAccessManagementWithStore` receives a valid `filerClient` to avoid potential nil pointer dereferences or limited functionality. * clean: remove dead code in s3api_server.go * refactor(s3api): improve IAM initialization, safety and anonymous access security * fix(s3api): ensure IAM config loads from filer after client init * fix(s3): resolve test failures in integration, CORS, and tagging tests - Fix CORS tests by providing explicit anonymous permissions config - Fix S3 integration tests by setting admin credentials in init - Align tagging test credentials in CI with IAM defaults - Added goroutine to retry IAM config load in iamapi server * fix(s3): allow anonymous access to health targets and S3 Tables when identities are present * fix(ci): use /healthz for Caddy health check in awscli tests * iam, s3api: expose DefaultAllow from IAM and Policy Engine This allows checking the global "Open by Default" configuration from other components like S3 Tables. * s3api/s3tables: support DefaultAllow in permission logic and handler Updated CheckPermissionWithContext to respect the DefaultAllow flag in PolicyContext. This enables "Open by Default" behavior for unauthenticated access in zero-config environments. Added a targeted unit test to verify the logic. * s3api/s3tables: propagate DefaultAllow through handlers Propagated the DefaultAllow flag to individual handlers for namespaces, buckets, tables, policies, and tagging. This ensures consistent "Open by Default" behavior across all S3 Tables API endpoints. * s3api: wire up DefaultAllow for S3 Tables API initialization Updated registerS3TablesRoutes to query the global IAM configuration and set the DefaultAllow flag on the S3 Tables API server. This completes the end-to-end propagation required for anonymous access in zero-config environments. Added a SetDefaultAllow method to S3TablesApiServer to facilitate this. * s3api: fix tests by adding DefaultAllow to mock IAM integrations The IAMIntegration interface was updated to include DefaultAllow(), breaking several mock implementations in tests. This commit fixes the build errors by adding the missing method to the mocks. * env * ensure ports * env * env * fix default allow * add one more test using non-anonymous user * debug * add more debug * less logs |
