iam: GetUserPolicy returns NoSuchEntity for a policy name the user does not have (#11944)
* iam: GetUserPolicy returns NoSuchEntity for a policy name the user does not have When the user has stored inline policies, an unknown name fell through to the policy rebuilt from the user's actions, so a deleted policy still read back. The standalone IAM server already returns NoSuchEntity here. * iam: return service failure when listing inline policies fails A ListUserInlinePolicies error in GetUserPolicy fell through to action-based reconstruction, masking a store failure as a policy document. Propagate it as ServiceFailureException instead, matching the standalone iam server and the other callers in this file. * iam: return service failure when the inline policy store read fails --------- Co-authored-by: chrislusf <chrislusf@users.noreply.github.com> Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> |

s3: gate POST Object acl fields behind PutObjectAcl (#11939)
* s3: gate POST Object acl fields behind PutObjectAcl The POST Object handler promotes acl and x-amz-grant-* form fields onto the upload's ACL headers, and resolveFileMode honors the promoted canned ACL. The PUT path only applies such headers after an s3:PutObjectAcl grant; mirror that on POST by running the shared per-key authorization with the WriteAcp action whenever the request carries ACL headers. * s3: cover the POST Object acl gate Signed POST requests carrying an acl form field are denied for a writer without the WriteAcp action and for a writer a bucket policy denies s3:PutObjectAcl on the target key; the authorization boundary is exercised directly as well. * s3: cover x-amz-grant-* POST fields and the no-ACL case * s3: encode POST policy conditions as JSON in the acl-gate test |

command: keep filer, s3, and sftp up when the local unix socket cannot bind (#11999)
* pb: share the stale-socket tolerant unix listener ServeGrpcOnLocalSocket already treats the local socket as optional; pull the remove-and-listen block out so the filer, s3, and sftp http sockets can use it too. * command: keep filer, s3, and sftp up when the local socket cannot bind A stale socket file owned by another uid (e.g. left in /tmp by a containerized job) made os.Remove fail with EPERM and the Fatalf took the whole server down. The gRPC local socket already treats the unix listener as optional; do the same for the http/sftp sockets. * filer: clear shared localSocket flag when the unix socket cannot bind s3.localFilerSocket and (in weed server) the sftp local socket share the filer's -localSocket flag pointer. If the filer cannot bind the socket it now keeps running without it, so consumers still holding the configured path would dial a dead or foreign-owned socket. * command: keep sftp on its own localSocket flag under weed server sftpOptions.localSocket was overwritten with the filer's -localSocket flag, so -sftp.localSocket was ignored and an explicit filer socket path made the sftp server try to bind the same socket the filer already held. * s3: fall back to TCP when the filer local socket cannot be dialed The embedded S3 server copies the filer's -localSocket flag before the filer tries to bind it, so a socket that never comes up left every filer HTTP request dialing a dead path. Try the unix socket first and fall back to the request's TCP address on dial failure. * filer: keep the shared localSocket flag read-only after startup Clearing *fo.localSocket raced with the embedded s3 goroutine reading the same flag pointer and could not help a reader that had already copied it. The s3 filer client's TCP fallback covers the unbound-socket case without mutating shared flag state. |

s3: end a catalog-vended session with the access key it was vended for (#11945)
* s3: end a catalog-vended session with the access key it was vended for A table credential the Iceberg catalog vends is a self-contained STS session: it stays valid until it expires (an hour by default) even after the access key that loaded the table is deleted or deactivated, or its identity is removed or disabled. An operator revoking a leaked key cannot cut off the table credentials that key already obtained. Sessions are stateless JWTs, so there is no revocation list to consult. This change follows the same pattern as role sessions, which are already refused once their role's ID no longer matches (checkSessionRoleBinding): a vended session carries the access key it was vended for (src_ak, recorded by the previous change), and validateSTSSessionToken checks it against the identity table held in memory. A session of provider iceberg-catalog that carries a source key is refused (InvalidAccessKeyId, as for an unknown key) once its identity is gone or disabled, or the key is no longer one of that identity's active, unexpired credentials. Scope: - Only catalog-vended sessions are checked; web-identity, AssumeRole and every other STS session are validated as before. - The vendor binds a session to the caller's key only when the caller is a stored identity holding that key. A caller that signed with another STS session's key, an OIDC user, or a request that recorded no key gets an unbound session, as today; binding it would refuse every request made with it. A session minted before this change carries no key and is unbound. - The check is one map lookup under the read lock and a scan of one identity's keys (about 11 ns, 0 allocations, with 1,000 identities). Tests (s3api_iceberg_vended_session_test.go) mint real sessions through the catalog vendor and validate them the way a data-path request is validated: deactivating, expiring or deleting key A ends A's session while the session vended through key B on the same identity keeps working; disabling or deleting the identity ends it; callers that are not a stored identity holding the key get unbound sessions that keep working; other STS sessions are not checked. The first two tests and the third fail without this change. * s3: keep the vended-session key binding when the key dies before vend vendedSessionKeyLive gated the binding, so a key revoked between the request's authentication and the vend skipped it and minted an unbound session that stayed usable until it expired. Every catalog auth path pairs the identity name in context with the key that authenticated, so a stored-identity principal always means the request signed with that identity's own key. Bind whenever the principal is a stored identity: a session bound to a now-dead key is refused on its first request, which is what the binding is for. * s3: gate the vended-session key binding on the authenticated caller type lookupByIdentityName(principal) named only that some identity exists, not that the request signed with a stored key: an STS session or OIDC principal that collides with an identity name got a session bound to its temporary key, which vendedSessionKeyLive then refused on every request. Verifiers now record the verified key as a stored credential, and the vendor binds only when that marker is present — keeping the binding even when the key was revoked between authentication and the vend. * s3: enforce the vended key binding under a dedicated claim Sessions minted before the binding existed carry the caller's key in the audit-only SourceAccessKeyId — including temporary STS keys that can never resolve in the identity table. Enforcing on that field would end live table credentials at upgrade; the binding now travels under BoundAccessKeyId, leaving legacy sessions unbound as before. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3: bind vended sessions to a credential fingerprint The key id alone cannot identify a credential: an operator can delete a key and re-create it under the same id with a different secret, reviving sessions minted for the original. Verifiers now record a fingerprint of the secret at authentication; the session dies unless it still matches. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3: keep recording the caller's key on every catalog session SourceAccessKeyId was unconditional audit metadata before the binding existed; gating it on the stored-credential marker dropped the record for callers that authenticated another way. With the binding under its own claim there is no ambiguity left, so the field records the caller's key again regardless of how it authenticated. * s3: key the vended-session credential fingerprint with the signing key The bound-credential fingerprint travels inside the vended session token. As a plain SHA-256 of the secret it gave any token holder an offline guessing oracle for weak secrets, and CodeQL flags it twice. Store the verified secret in the request marker instead and HMAC it with the STS signing key at vend and at validation. The claim can no longer be mined, and the per-request auth path stops hashing secrets. --------- Co-authored-by: Javier de la Torre <jatorre@lakehousebox.com> Co-authored-by: Chris Lu <chrislusf@users.noreply.github.com> Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> |

s3 lifecycle: route version-file writes to current-version expiration (#11956)
* s3lifecycle: schedule ExpirationDays from version-file writes On a versioned bucket a PUT lands in the meta-log as the version file plus the .versions/ directory update — there is no bare-key event, so the version-folder skip dropped every version-file event for all kinds but ExpiredDeleteMarker. ExpirationDays therefore only fired via the recovery walker's cold-start / rule-change pass: once a shard had a saved cursor, no daily run ever scheduled another delete marker. A version-file write is the latest for its logical key at write time, so route it through the same event-driven evaluation the regular path runs. The match carries the file's identity with an empty VersionID — the dispatcher resolves the current latest at due time, and a fresher PUT meanwhile resolves to STALE_IDENTITY there.

iam/oidc: reject reused jti claims with a bounded replay cache (#11936)
* iam/oidc: reject reused jti claims with a bounded replay cache * iam/sts: pass jti replay settings through convertToOIDCConfig * iam/oidc: keep consumed jtis and stop the cleanup worker across re-init Re-initializing a provider reset the JTI store, so an already-used token could be presented again after a config refresh; the store is now allocated once and survives Initialize. The cleanup worker is stopped on every re-init (previously only when protection stayed enabled), is started only after the rest of Initialize has succeeded, and Shutdown no longer consumes a permanent sync.Once, so a re-initialized worker can be stopped again. * iam/oidc: enforce the jti replay cache bound for every token Tokens without a usable jti claim skipped the cache entirely and stayed reusable; they are now keyed by the token's own fingerprint so a repeat presentation is still a replay. Tokens without exp previously failed as expired on first use; their entry now gets a bounded retention. The replay test-and-set now runs before any capacity work so replayed tokens cannot each trigger a full-cache scan, the entry count is incremented as part of the insert so concurrent validations cannot overshoot the bound, and a guaranteed serialized sweep runs before a capacity rejection while opportunistic sweeps are rate limited and confined to one at a time. Raw token identifiers are no longer written to logs or errors, a stable fingerprint is logged instead. * iam/sts: shut down providers dropped by the managed-provider swap Each managed OIDC provider runs a background JTI cleanup worker, but SetIAMManagedOIDCProviders replaced the provider map without stopping the old providers, so every refresh leaked goroutines. Providers absent from the new map are now shut down; providers that stay keep running. * iam/integration: reuse providers across refreshes for unchanged records Every refresh rebuilt providers from their records, so a refreshed provider forgot the JTIs it had already consumed and an already-used token could be presented again. Records are now fingerprinted and an unchanged record reuses its provider, keeping the consumed-token cache; changed records are rebuilt, removed records are dropped, and the swap in STS releases the workers of whatever is no longer referenced. * iam/oidc: consume replay entries only on the single-use exchange path Bearer authentication validates the same token on every request, so consuming it in shared ValidateToken/Authenticate made every token single-use and rejected all but the first request. The replay check now runs only for the STS exchange via AuthenticateSingleUse; bearer paths validate without consuming. A token without exp also no longer gets a bounded replay entry that ages out while the token stays valid: its entry is kept until the capacity bound evicts it, so it can never become usable again. * iam/oidc: keep the mock provider on the mock path for single-use calls * iam/oidc: require exp on single-use tokens A cache slot frees only by expiry, so an expiry-less entry would hold it forever; a burst of distinct tokens could exhaust the bound permanently and block every later exchange. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3: give each web-identity test token a unique jti Subtests minted tokens with identical claims inside one second, so the exchange saw the same token fingerprint twice and the second call read as a replay. Each exchange now carries its own jti. * iam/oidc: carry the consumed-token replay store across provider rebuilds A record change rebuilds the managed provider with a fresh JTI store, so a token consumed before the rebuild could be presented again until it expired. The new provider adopts the replaced provider's replay store before it is published, and the replaced provider is shut down so only one cleanup worker sweeps the shared store. * iam/oidc: stop the cleanup worker of providers dropped from the store A refresh removed the provider object from the managed cache but left its JTI cleanup goroutine running for the life of the process. * iam/oidc: merge a provider's consumed replay entries into another's store MergeReplayStateFrom folds one provider's consumed-token entries into another's, skipping already-expired ones. Unlike AdoptReplayStateFrom it swaps no pointers, so it is safe on a provider still serving validators. * iam/integration: share one provider and replay store across identical issuer records Records for the same issuer URL with identical validation settings now reuse a single provider, so a token consumed through one account's record is rejected through the other's — previously each record owned a separate jti store and a spent token could be replayed cross-account. A superseded provider's consumed entries merge into the shared store so no rejection is lost, and a removed or rebuilt provider is only shut down once no remaining record references it. * iam/oidc: hand the superseded provider's live replay store to the shared one * iam/oidc: carry merged replay entries without charging the capacity bound * iam/oidc: key the jti-less replay fingerprint on the signed input Hashing the whole token lets ECDSA signature malleability (s -> N-s) mint a second cache key for identical claims, so a consumed token could be replayed for another exchange. Key the fallback on header.payload instead. * iam/oidc: publish the jti cache bound before the enabled flag Initialize stored jtiEnabled ahead of jtiMaxSize, so a provider flipped from disabled to enabled exposed enabled=true with a zero bound for a window; a single-use validation landing there would compute newCount > maxSize and reject with "JTI cache capacity exceeded". Store the bound first so the flag is the last thing published.

s3: bound ListMultipartUploads memory to the page size (#11971)
* s3: bound ListMultipartUploads memory to the page size listMultipartUploads loaded every open upload in the bucket into a slice and selectMultipartUploads filtered and sorted a second full copy, so one request cost O(total open uploads) heap regardless of prefix, key-marker, or max-uploads; concurrent calls multiplied it and could OOM the gateway. The response is ordered by the object key kept in extended attributes, not the upload id the filer sorts by, so every entry still has to be seen. Streaming the listing into a bounded top-K collector keeps at most maxUploads (capped at maxUploadsList) candidates, bounding heap by the page instead of the folder. A caller-supplied max-uploads above the server cap now also paginates rather than accumulating unboundedly.

operation: renew the write JWT when a fan-out rollback delete is rejected (#11970)
* operation: renew the cleanup JWT when a fan-out rollback delete is rejected A stalled holder can out-wait the assignment JWT's 10s expiry, so the type=replicate delete that rolls back landed copies comes back 401 and the needle leaks. Retry the delete once with a fresh token minted through the new LookupJwtFunc hook when a holder answers unauthorized. * s3api: wire a cleanup-JWT renewer into chunked uploads Keep the master client on the server and use it to mint fresh volume JWTs for rollback deletes that run past the assignment token's expiry. * admin: wire a cleanup-JWT renewer into file-browser uploads * operation: bound the cleanup-JWT renewal with a per-attempt deadline A rollback delete that hits 401 renewed the token through a background context, so a master outage could park the wait for a connection and the lookup RPC inside the failed upload's cleanup path. Thread a context through LookupJwtFunc and LookupJwt, and bound each renewal with a 10s deadline covering both the master wait and the lookup call. * operation: let every holder's 401 retry with a renewed cleanup JWT A single renewed flag meant only the first rejecting holder refreshed the token; a holder that stalled past the renewed JWT's lifetime left later copies stranded with a 401 they could not resolve. The retry limit is now per holder — each delete is attempted once with the current token and once more after a bounded renewal — so a slow middle holder cannot strand the rest. * operation: log the volume server's error body on a failed cleanup delete Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * operation: count test upload attempts atomically The chunk upload loop fans AssignFunc out to parallel goroutines, so the plain int counter in the partial-results test raced under -race.

s3api: support s3:RequestObjectTag/<key> in bucket policies (#11910)
* s3api: support s3:RequestObjectTag/<key> in bucket policies The tags come from X-Amz-Tagging only where the handler stores them from there: not on PutObjectTagging, which reads the body, and not on a copy that keeps the source's tags. For a repeated key the last value counts, since that is what CopyObject stores. * s3api: extract RequestObjectTag only where the handler stores it The header was honored on any request carrying it, so a tag attached to a GET, DELETE, part upload, multipart completion, directory marker or a PUT subresource satisfied a tag-conditioned policy the object never receives. Extraction now follows the handlers: PutObject, a copy under X-Amz-Tagging-Directive: REPLACE, and CreateMultipartUpload store the header; a plain object PUT is identified by carrying only X-Amz-* signing parameters. * s3api: exclude multipart part PUTs before the copy-source check A PUT carrying X-Amz-Copy-Source plus a numeric partNumber and uploadId routes to CopyObjectPartHandler, which stores a part and never reads X-Amz-Tagging. Checking the copy source first let such a request satisfy an s3:RequestObjectTag condition under REPLACE with tags that are never stored. Mirror the router: the part handlers match only when both partNumber (digits only) and uploadId are present, so a lone or non-numeric partNumber still falls through to the storing handlers.

s3, iceberg: record the access key a request was signed with (#11901)
* s3, iceberg: record the access key a request was signed with Several access keys can belong to one identity, but nothing downstream of authentication says which one signed a request: the audit log carries the identity name only, and every table credential the Iceberg catalog vends for that identity gets the same session name. When an identity is shared (one key per person or per service), the log cannot tell the holders apart. The verifier that matched a credential now records that credential's access key id in the request's identity holder (verifyV4Signature for header, presigned, streaming and STS requests; both SigV2 verifiers). Nothing re-reads the request for a key, so a second, unverified key elsewhere in the request (a junk X-Amz-Credential on a SigV2 request, a junk SigV4 header on a SigV2 presigned URL) is never recorded. - s3err.AccessLog gains access_key_id (omitempty): a static key's id, or an STS session's temporary key id. Every other field is unchanged. - The Iceberg and Lance catalogs install the holder before authenticating a SigV4 request; a Bearer token records the key it was minted from (the token is verified with a key derived from it); a Lance x-api-key records its key. - VendTableCredentials ends the session name with "-k" and the first 12 hex digits of SHA-256 of the key id (the table part gives way within the 64-character limit; the tag is never cut), and carries the key id in the session token (src_ak, SessionInfo.SourceAccessKeyId). Tests: auth_access_key_attribution_test.go and auth_access_key_shapes_test.go (two keys on one identity, the deny path, SigV2 and presigned SigV2 with a junk key elsewhere, streaming seed, STS session, failed signatures record nothing), s3api_iceberg_session_name_test.go, iceberg and lance Auth tests, sts source_access_key_test.go. * s3: record the access key of a verified POST-policy form and of a retargeted signature Two verified signatures left access_key_id empty in the audit log: - A browser POST upload is verified in PostPolicyBucketHandler from its form fields by doesPolicySignatureV2Match / doesPolicySignatureV4Match, which did not record the key. Both now take the request context and record the credential's key once its signature verifies; a form that fails verification records nothing. - verifyV4Signature refuses a signature that verified for one virtual-hosted bucket but was routed to another. The key was recorded only after that check, so the refusal carried none. It is now recorded as soon as a host candidate verifies. Test: TestPostPolicyUploadRecordsTheSigningKey (SigV4 and SigV2 forms, and a form with a wrong signature) and TestSignedVirtualHostRetargetRecordsTheSigningKey; both fail before this change. * s3: test VendTableCredentials end to end for the caller's access key TestVendTableCredentialsRecordsTheCallersKey mints sessions through VendTableCredentials with a configured STS service, the key recorded the way the catalog's authentication records it, then validates each session token: SourceAccessKeyId and the session name's key tag match the key, and a caller without a key gets an untagged session. It fails if the vendor stops passing either field. --------- Co-authored-by: Javier de la Torre <jatorre@lakehousebox.com> Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> |

iam: optionally require an iam: grant for self-service access-key actions (#11937)
* iam: optionally require an iam: grant for self-service access-key actions
AuthorizeIamAction lets every authenticated identity run CreateAccessKey,
DeleteAccessKey, UpdateAccessKey, ListAccessKeys and GetUser on itself with
no grant. On AWS these actions need an IAM policy (the usual one grants them
on arn:aws:iam::*:user/${aws:username}); nothing is allowed implicitly.
Where identities hold data-plane rights only, the implicit carve-out lets a
leaked key mint further keys for its own identity, with no cap, that keep
working after the operator deletes the key that leaked; it can also
deactivate or delete the keys the operator issued.
A new option, off by default, makes these actions need the iam:<Action> grant
like every other IAM action: -s3.iam.selfServiceRequiresGrant on weed
server, filer and mini, -iam.selfServiceRequiresGrant on weed s3. With it
set, the grant is authorized against the target user's ARN, the caller's own
when UserName is empty, so a policy can confine it to the caller's own keys
(Resource arn:aws:iam:::user/${aws:username}), the same resource scoping
CreateServiceAccount already uses. The admin and iam:* grants are unchanged;
with the option off nothing changes.
Tests (s3api_embedded_iam_authz_test.go): with the option set, an identity
holding only s3:* and a bare identity are refused all five actions on an
empty, own and other target (fails without the change); a grant on the
caller's own user ARN, literal or ${aws:username}, allows them on itself and
not on another user; the admin and an iam:* grant keep every action; with the
option off self-service is allowed as before.
* iam: wire selfServiceRequiresGrant on the standalone iam server
Every other command that runs the embedded IAM API accepts the flag; the
deprecated weed iam could not enable the enforcement at all.
* iam: wire selfServiceRequiresGrant on weed server and filer -iam
The IamOptions used by 'weed server -iam' and 'weed filer -iam' never
received the flag, so startIamServer dereferenced a nil pointer at
startup. Share the -s3.iam.selfServiceRequiresGrant pointer with them.

s3: keep '\' a literal object-key character behind -s3.allowBackslashInKey (#11911)
* s3: keep '\' a literal object-key character when AllowBackslashInKey is set NormalizeObjectKey rewrites every S3 object key: '\' becomes '/' and duplicate slashes collapse. On AWS S3 both are ordinary key characters, so keys that are distinct there alias one object here — writing probe/back/slash.txt silently overwrites probe/back\slash.txt. The filer only treats '/' as a path separator, so a verbatim '\' stays inside one entry name. Gate the backslash rewrite and the matching '\' handling in IsValidObjectKey behind a process-wide mode the S3 server sets from the new S3ApiServerOption. Duplicate-slash collapsing stays: an entry name cannot contain an empty segment.

iceberg: authorize a commit before staging its metadata file (#11891)
* iceberg: authorize a commit before staging its metadata file Both commit paths (CommitTable and CommitTransaction) write the new vN.metadata.json into the table's metadata/ directory and only then reach UpdateTable, whose authorization refuses a caller that may read the table but not commit to it. The refused commit then deletes the staged file on the way out, so such a caller could make the server write and delete a file under the table's prefix on every attempt. The same shape was closed for creates in #10991. Both paths now ask Manager.AuthorizeUpdateTable right after loading the table and answer 403 ForbiddenException before anything is staged. UpdateTable still decides under the policies in force when the pointer flips, so a policy changed mid-commit is caught as before. Test: TestCommitDeniedBeforeStagingMetadata records every file the handlers create; on master both the single-table and the transaction commit by a GetTable-only identity write v2.metadata.json before answering 403, with the change nothing is written. TestCommitAllowedStagesMetadata is the positive control (the owner, and an identity whose own actions include UpdateTable). * iceberg: authorize a view commit before staging its metadata handleUpdateView has the same write-before-authorize gap the table commit paths had: it stages the new metadata file and only reaches the UpdateView authorization at the pointer flip, so a caller who may only load the view could still make the server write and delete files under it. Gate it on AuthorizeUpdateView, mirroring authorizeCommit. * iceberg: seed committed view metadata in the denied-commit test Without stored view metadata the request fails on the missing-metadata check before it could stage a file, so the zero-write assertion could not catch a write-before-denial regression. Seed the same metadata the allowed-path test uses so the denied request would otherwise stage. --------- Co-authored-by: Javier de la Torre <jatorre@lakehousebox.com> Co-authored-by: Chris Lu <chrislusf@users.noreply.github.com> |

s3: resolve versionId ACL and attributes requests to the version-scoped actions (#11916)
* s3: resolve versionId ACL requests to the version ACL actions A request for an object's ACL carrying versionId acted on the historical version but authorized against the current-object action (s3:GetObjectAcl/s3:PutObjectAcl), because the acl block in resolveFromQueryParameters returned before versionId was considered - the same gap closed for tagging. An identity granted only current-object ACL access - or explicitly denied s3:*ObjectVersionAcl - could still read and modify ACLs on noncurrent versions. ?acl&versionId=<id> on an object now resolves to s3:GetObjectVersionAcl/s3:PutObjectVersionAcl; ?acl alone keeps the current-object actions and bucket ACL is unaffected. s3:PutObjectVersionAcl is mapped onto the WriteAcp identity action so policies can name it. * s3: resolve versionId attributes requests to the version attributes action GET /bucket/key?attributes&versionId=<id> fetched the historical version's attributes but authorized against s3:GetObjectAttributes, so a grant limited to the current-object attributes action could reach noncurrent versions. The request now resolves to s3:GetObjectVersionAttributes, and both attributes actions map onto the Read identity action so policies can name them (s3:GetObjectAttributes was previously rejected as an unmapped action). * s3api: recheck the version action on versioned ACL/attributes requests The phase-2 policy recheck inside GetObjectAclHandler, PutObjectAclHandler, and GetObjectAttributesHandler passed the current-object action even when the request carried versionId and phase 1 had resolved the version action. A Deny scoped to s3:*VersionAcl or s3:GetObjectVersionAttributes could never fire in the recheck, and an Allow limited to the version action went unevaluated.

s3tables: accept the external-volume verification object at a table bucket's root (#11900)
* s3tables: accept the external-volume verification object at a table bucket's root Snowflake verifies an S3-compatible external volume before it creates or writes Iceberg tables in it (SYSTEM$VERIFY_EXTERNAL_VOLUME, also run implicitly): it writes, reads, lists and deletes one small object, <base>/verify_<epoch milliseconds>_<number>, a 21-byte body. A table bucket refuses every key outside the Iceberg layout, so the check failed and Snowflake could not use a table bucket as an external volume. PUT, GET, HEAD, DELETE and DeleteObjects now accept exactly that key in a table bucket, narrowly enough that it cannot be used to store data: - at the bucket root only, so nothing is encoded in a prefix, written into a hidden tree or placed on a namespace or table name; - one shape: verify_<13 digits of epoch ms within one hour of the server's clock>_<1-10 digits>; - a PUT must declare a Content-Length of at most 1 KiB (no chunked or undeclared body) and carry no user metadata, tagging, Content-Disposition, Cache-Control, Expires or website redirect. Multipart, copy, rename, ACL, tagging and POST policy writes keep the plain layout rule. Buckets that are not table buckets are unaffected. Tests: table_bucket_verify_object_test.go, the key accepted (with the Iceberg layout as the positive control and the plain rule still refusing it), 15 look-alikes refused (prefixed, hidden tree, wrong shape, outside the window, ordinary keys), and seven PUT refusals through PutObjectHandler. * s3tables: keep the verification key off namespaces and narrow its PUT A namespace may be named like a verification key (verify_<ms>_<n>), and the key then names the namespace's directory. A PUT replaced that directory with a prefix object, dropping the namespace's catalog metadata; a DELETE removed an empty namespace. The key now gets the plain layout rule when it names a directory or its entry cannot be read, and a PUT of it never falls back to a prefix object, so a namespace created after the check is not replaced either. The time window applies to PUT only: GET, HEAD and DELETE take a key of any date, so an object a check left behind for more than an hour can still be read and removed. A verification PUT also refuses an extraction request and the stored Content-Language, Response-Content-Disposition and Content-Encoding headers (aws-chunked framing alone is still accepted). The integration test runs the check's PUT, HEAD, GET, list and DELETE against a table bucket, and the PUT and DELETE over a namespace of the key's shape. --------- Co-authored-by: Javier de la Torre <jatorre@lakehousebox.com> |

s3: answer InvalidBucketName to a denied request on a malformed bucket name (#11893)
* s3: answer InvalidBucketName to a denied request on a malformed bucket name The store authorizes a request before it looks at the bucket, so a caller denied on a bucket whose name breaks the S3 naming rules (upper case, an underscore, too short, two adjacent periods, a non-ASCII letter) gets 403 AccessDenied, where AWS S3 answers 400 InvalidBucketName. Clients and compatibility suites that check the error code read the 403 as a permission problem. Auth and AuthPostPolicy now turn an AccessDenied for a resolved identity into InvalidBucketName when the bucket name fails VerifyS3BucketName or uses a character outside a-z, 0-9, '.' and '-' (VerifyS3BucketName checks with unicode.IsLower/IsNumber, which accept letters such as 'ü'). The answer depends on the name alone, so it reveals nothing about which buckets exist. An authentication failure, an allowed request and a denial on a well-formed name answer as before. Test: TestAuthDeniedInvalidBucketName drives iam.Auth with signed and anonymous requests; on master every malformed name answers 403, with the change 400, while the identity's own bucket stays allowed and a well-formed foreign name stays 403. TestRefineDenialForBucketName covers the rule table. * s3: refine POST-policy and deferred anonymous-read denials on a malformed bucket name Two denial paths bypass the refinement in Auth and AuthPostPolicy: - A browser POST upload carries its credentials in the form, so AuthPostPolicy delegates it to PostPolicyBucketHandler, which verifies the form and writes AccessDenied itself when the signer may not write the bucket or the per-key authorization denies the object. Both denials now go through refineDenialForBucketName with the verified identity. The coarse Write check used to run inside doesPolicySignatureV2Match and doesPolicySignatureV4Match before the signature was compared, so a form with a wrong signature was told whether the key may write the bucket. It now runs in doesPolicySignatureMatch after the signature verifies, as on the header-signed path; a form that fails verification answers SignatureDoesNotMatch (or MissingFields) and is never refined. - Unsigned GET/HEAD object reads are deferred by AuthWithPublicRead to the object handlers, where writeAnonymousAwareNotFound masks a miss as AccessDenied. That denial is refined with the anonymous identity, so a missing malformed bucket answers InvalidBucketName when an anonymous identity is configured, as Auth does. A denial on an entry that was found is left alone: the bucket exists. Test: TestPostPolicyDeniedInvalidBucketName drives AuthPostPolicy with signed forms (Write denied, per-key policy deny, bad signature, well-formed name); TestAnonymousReadDeniedInvalidBucketName drives AuthWithPublicRead with GET and HEAD, with and without an anonymous identity. Both fail before this change. * s3: refine a denied anonymous read of an existing key on a malformed bucket name A deferred anonymous GET/HEAD refined only its masked miss to InvalidBucketName, so in a bucket whose name breaks the S3 rules (one VerifyS3BucketName still accepts, such as a non-ASCII name) a missing key answered 400 and an existing private key 403, telling the caller which keys exist. The entry check now refines its denial the same way, so both answer alike. Without an anonymous identity no identity resolves and both stay 403, as in Auth. The deny-precedence case in TestAnonymousObjectACLConfiguredIdentity runs on the fixture bucket "b", shorter than S3's three-character minimum, so its denial now answers InvalidBucketName. --------- Co-authored-by: Javier de la Torre <jatorre@lakehousebox.com> |

s3: no empty-directory marker in a "<dir>/" self-prefix listing (#11906)
An out-of-band empty directory listed under its own trailing-slash prefix answered the probe with a fake entry of itself: a Contents key on 4.48 and, since recently, a CommonPrefix.

s3tables, iceberg: log client refusals at V(1), not ERROR (#11896)
* s3tables, iceberg: log client refusals at V(1), not ERROR Requests the S3 Tables and Iceberg REST APIs correctly refuse with a 4xx (access denied, not authorized, no such namespace, already exists, not empty, a commit conflict) were logged with glog.Errorf, so a client probing for what it may do, or retrying an optimistic commit, filled the ERROR log and hid real faults from anyone alerting on it. - s3tables: HandleRequest wraps the ResponseWriter in a statusRecorder (with Unwrap for http.ResponseController) and logs a handler error by the status it answered: 4xx at V(1) as "<op> refused (<status>)", 5xx or no status at ERROR as before. - s3tables: the "handleCreateNamespace called" trace moves from ERROR to V(3). - iceberg: writeManagerError's mapping is split into classifyManagerError, shared with a new logManagerError that logs 4xx-mapped errors at V(1) and everything else at ERROR; used by CreateNamespace, CommitTable and CommitTransaction. - storage: loading a remote-tier volume logged "readSuperBlock remote volume N: <nil>" at ERROR even when the read succeeded; it is now logged only when there is an error. Tests: TestRequestRefusedWith4xxIsNotLoggedAsError, TestLogRequestErrorByStatus, TestStatusRecorderKeepsTheFirstStatus, TestStatusRecorderUnwrapsForResponseController, TestNoTraceLoggedAtErrorLevel (fails on master on the CreateNamespace trace), TestLogManagerErrorRefusalsAreNotErrors, TestRemoteSuperBlockLogOnlyOnError. * s3tables: do not log a malformed CreateNamespace body at ERROR handleCreateNamespace logged a body it could not decode at ERROR before answering 400; the dispatcher already logs that refusal once at V(1).

Unwrap already lets the controller reach the wrapped writer. * iceberg: require exactly one log line per classified manager error The test accepted a refusal that produced no log, or both logs.

s3: apply Range to HeadObject (#11856)
* s3: apply Range to HeadObject * s3: apply Range to a HEAD of a stored directory key Directory-key entries answer through serveDirectoryContent before HeadObjectHandler's range branch, so a ranged HEAD returned 200 and the full length. * s3: keep the missing-directory check for plain directories only A stored directory-key marker is an object, so a range on its empty body answers 416 like on any other zero-byte object. * s3: let partNumber keep its priority over Range on a directory key HEAD * s3: serve ranged GETs of a stored directory key The same branch now applies the validated range to the inline content on GET, so a directory-key object answers 206 with the selected bytes like any other object. --------- Co-authored-by: Chris Lu <chrislusf@users.noreply.github.com> |

s3tables: judge an absent tag target by its canonical ARN (#11912)
* s3tables: judge an absent tag target by its canonical ARN authorizeAbsentTarget matched the bucket policy's Deny statements against the request's raw resource ARN. The ARN parsers accept any account and region but resolve the target by name, so a caller with an identity grant could reformat the ARN, miss the Deny match, and learn whether a denied name exists — the oracle the absent-target check was meant to close. Rebuild the ARN from the resolved names and the real bucket owner and evaluate the Deny against that, matching what the existing-target path checks.

s3tables: keep absent-target answers identical to denied ones (#11905)
* s3tables: authorize before revealing a list or tag target exists ListTables, ListViews and the tag operations read the target's catalog metadata before any permission check, so a denied caller could tell an existing name (403 or the resource's own error) from an absent one (an empty list, or 404). Evaluate the operation's permission with whatever bucket context could be read and answer a denied caller the same way for absent, damaged and denied targets.

iam: take the implicit user name from the verified identity (#11903)
* iam: take the implicit user name from the verified identity For self-service actions sent without UserName, the implicit user was resolved by re-parsing the raw Authorization header for a SigV4 credential and looking that access key up. The header is not what authentication verified: a request can be authenticated by one mechanism while carrying a header that names another user's access key, and the action then ran against that other user. The auth middleware already records the verified identity in the request context, so use it, on both the standalone iam server and the embedded IAM surface. When no verified identity is present the name is left unset rather than guessed. * iam: test implicit user name resolution Cover a request authenticated by presigned credentials that also carries a junk SigV4 header naming another user: the self-service actions must run as the verified signer. Update the unit tests for the context-based lookup. * iam: resolve the implicit user for standalone GetUser too The embedded surface fills UserName for GetUser; the standalone server skipped it, so an implicit GetUser on `weed iam` answered NoSuchEntity. Same verified-identity source as the other self-service actions. * iam: cover all implicit-username actions in the regression test |

s3tables: accept Puffin statistics files in a table's metadata/ (#11892)
Table and partition statistics are Puffin files that the table metadata lists in its statistics entries; orphan cleanup keeps them (#11651), and its test places one at metadata/stats-1.puffin. The table bucket layout rule accepted only *.stats among them, so an engine that names a statistics file *.puffin had the upload refused with 403 and could not write statistics at all. The metadata patterns now admit a *.puffin file directly under metadata/, with the same safe-character rule as the other catch-all patterns. Nothing else widens: a Puffin file in a subdirectory of metadata/, with a trailing extension, or outside <namespace>/<table>/ is still refused. Test: the new metadata/*.puffin cases in TestIcebergLayoutValidator_AcceptsRealWorldManifestNames and TestTableBucketFileValidator_PuffinStatisticsOnlyInTableMetadata fail on master ("invalid metadata file format") and pass with the change; the rejected cases pass on both.

s3, s3tables: create buckets and namespaces exclusively (#11872)
* filer_pb: add MkdirExclusive A taken name leaves the callback as a result, not an error, so filer failover does not count a lost race as a filer failure. * s3tables: create the entry with its attributes in one exclusive create CreateTableBucket and CreateNamespace checked that the name was free and then wrote the entry in several calls, so a second create in the window replaced the first caller's entry including its owner. The create now carries the marker, metadata and tags in one O_EXCL CreateEntry that answers ErrEntryAlreadyExists with the same 409. * s3: PutBucket uses an exclusive mkdir The same window let a plain PutBucket replace a table bucket created concurrently. The already-exists branch now answers from the entry itself, since the registry just cached the name as absent, and the admin auto-create path is exclusive too. * s3: read the winning entry when a create loses the race The concurrent-create branch called existingBucketError on a name the registry had just cached as absent, answering NoSuchBucket, and the auto-create fallback could assign an S3 owner to a table bucket it met there. The negative cache is cleared before the existing-bucket error is built, and a table bucket keeps its owner-less shape. * s3: fail an auto-create that met a table bucket A table bucket carries no S3 owner and must not gain one, and the upload that auto-create ran for must not continue into it either. * s3: fail an auto-create when the winning entry cannot be read An unreadable existing entry fell through to success, so the write continued into an unvalidated entry, possibly a table bucket. |

s3tables: only the admin repairs a table bucket that has no owner metadata (#11873)
* s3tables: only the admin repairs a table bucket that has no owner metadata CreateNamespace wrote bucket metadata naming the caller as owner before any permission check ran, so an ordinary caller that found the marker without metadata was written in as the bucket's owner and passed every check after. A bucket in that state is answered with the operation's own denial; the admin or a trusted internal handler may still repair it. * s3tables: repair the marker-only bucket under the entry lock A creator finishing its own create between the missing-metadata check and the repair write would have its owner overwritten. The mutation now adopts whatever metadata is there and writes only while it is still absent. * s3tables: gate the repair on the Admin action, not an operation grant hasAdminAction also answers s3tables:*, so a non-admin identity holding the wildcard operation grant could pass the repair check and write itself in as the bucket's owner. |

iam: targeted writes for single-user IAM actions (#11877)
* s3api: persist single-identity IAM changes through the credential manager CreateAccessKey, DeleteAccessKey, UpdateAccessKey, PutUserPolicy, DeleteUserPolicy, SetUserStatus, UpdateUser and DeleteUser used to load the whole configuration, change one identity and then SaveConfiguration, rewriting and re-propagating every identity.

s3: mask anonymous misses behind AccessDenied unless the bucket is listable (#11857)
* s3: mask anonymous misses behind AccessDenied unless the bucket is listable Deferred anonymous GET/HEAD authorization only runs once an entry is selected, so misses returned 404 while existing keys returned 403 — an unauthenticated existence oracle for bucket names and object keys. Route not-found responses in Get/HeadObjectHandler through a check that only discloses 404 when anonymous listing is allowed (policy, identity or a public-read bucket); otherwise the miss is indistinguishable from a denied read, matching AWS and 4.48 behavior.

Each check now runs on a request with a fixed shape: a ListBucket scoped to the probed key and a plain read of the key, so the miss only shows when the caller could learn the same fact directly. * s3: mask conditional-header misses for anonymous reads An If-Match conditional on a missing key wrote NoSuchKey directly from processConditionalHeaders, before the handlers reached the masked miss path, so anonymous callers could still distinguish a missing key from a denied read. * s3: keep the versionId when masking anonymous misses The read leg must evaluate the action the caller's request resolves to: a versioned miss is s3:GetObjectVersion, and dropping versionId would let a plain GetObject grant disclose versions the caller may not read. --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> |
