7603528aff 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.

* s3api: gate tag extraction on the routed subresource, not query key shape

Rejecting every PUT whose query held a key outside X-Amz- dropped
X-Amz-Tagging from ordinary object PUTs that carry arbitrary parameters —
Signature V2 presigns (AWSAccessKeyId/Signature/Expires) among them — so a
tag-conditioned Deny could be bypassed by appending an unrelated query
parameter while putToFiler still stored the tags. Exclude the object PUT
subresources the router actually dispatches (tagging, renameObject, acl,
retention, legal-hold) ahead of the copy-source check instead.

Chris LuandDevin cec96c02ea s3: reject requests carrying more than one routed subresource (#11942)
* s3: reject requests carrying more than one routed subresource

Routing picks the first matching subresource route while authorization
resolves a single action from the query, and the two can disagree. A
bucket-level PUT ?tagging&policy is authorized as s3:PutBucketTagging but
served by PutBucketPolicyHandler, letting a tagger rewrite the bucket
policy; the same shape lets a list grant read the policy via
?list-type=2&policy or ?versions&policy, and lets an object ACL writer
retag via PUT ?acl&tagging. Declining ambiguous requests keeps the
authorized action and the served handler identical.

* s3: reuse hasAmbiguousSubresource in the routed-subresource guard

The standalone key list dropped versioning, so ?versioning&policy still
reached route matching and auth with two operations. The bucket-level
check already keys off operationSubresources plus bucketQueryActions;
running the same predicate keeps the lists from drifting apart.

74da88fc29 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.

df33e81915 volume: report the needle read error with a failed read (#11934)
* volume: report the needle read error with a failed read

A read that fails on the volume server, for example on a CRC mismatch,

The volume server now writes the error into the response body, and the
read helpers add it to the error they return.

1aad4cfe70 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.

Chris LuandDevin c0152e6be1 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.

deleted while the stored entry survived. Echo the client-sent key in

body-key path. Such a key can never name a stored entry, so like a
missing key the delete is an idempotent no-op reported before any
permission check or filer call.

917b6f4afd 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.

Chris LuandDevin 106fd31af1 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. Select the action
the same way the resolver does — versioned whenever versionId is present.

Javier de la TorreandJavier de la Torre de2fc03c7d 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

Javier de la TorreandJavier de la Torre f40267db44 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.

Chris LuandDevin 6ee7c4c5c7 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

read every returned key (Pulumi lock listing) choked on the marker.

The prefix object and directory key object paths are unchanged: a real
"dir/" object still lists as its own key.

Javier de la TorreandJavier de la Torre 97f8ca13ff 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).

Also drop statusRecorder.Flush: it made the recorder an http.Flusher even
over a writer that cannot flush, so http.NewResponseController reported
success instead of ErrNotSupported. 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. Require
one V(1) refusal and no ERROR for a 4xx, and the reverse for a fault.

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.

* 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.

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.

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

Route not-found responses in Get/HeadObjectHandler through a check that

* 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.

Chris Lu 8d2b417c69 iceberg, lance: vend read-only credentials to callers that may only read (#11859)
* s3tables: share the UpdateTable authorization gate

Extract the validation, load, and permission check from handleUpdateTable
into authorizeUpdateTable so the table an update was authorized against is
the same snapshot the mutation writes to. Manager gains
AuthorizeUpdateTable, mirroring AuthorizeCreateTable, so callers can ask the
question without updating anything.

* s3tables: share the UpdateView authorization gate

Extract the lookup, policy load, and permission check from handleUpdateView
into authorizeUpdateView, mirroring authorizeUpdateTable, and expose it as
Manager.AuthorizeUpdateView for callers that need the answer without the
update.

* s3api: scope vended table credentials to read-only on request

VendTableCredentials takes a readOnly flag and tablePrefixSessionPolicy
emits only s3:GetObject for the table prefix when it is set, keeping the
conditioned ListBucket and unconditioned GetBucketLocation statements that
reads still need.

* iceberg: vend read-only credentials when the caller may not write

LoadTable and friends vend storage credentials only for the authority the
caller holds: the vend now checks UpdateTable/UpdateView permission and a
caller that may only read the catalog entry gets a read-only session. Paths
that just passed a write gate (stage-create, view commit) keep the full
session.

* lance: vend read-only credentials when the caller may not write

storage_options vends the same read-only session as the Iceberg catalog
when the caller lacks UpdateTable on the table.

* lance: keep write credentials for callers authorized to declare

A Lance commit is a direct S3 write that never revisits the catalog, so a
caller that just passed CreateTable still gets a writable session; the
UpdateTable gate applies to describe, the read path.

* iceberg, lance: log a failed write check instead of only reading it as denied

7ed26deaae s3: list keys in byte order around directory markers (#11832)
* s3: list keys in byte order around directory markers

* s3: order deferred dir blocks by slash name and hold quota

* s3: fix deferred dir blocks at page and marker boundaries

Review follow-ups on the marker byte-order change:

- A marker inside an emitted "<name>/" block re-descended and re-listed its
  folded contents under delimiter "/" instead of skipping the block.
- A prefix object's "<name>/" common prefix was emitted eagerly at the name
  position, outranking siblings like "a.txt" and repeating across pages; the
  plain key now emits alone at the name position and the block emits the
  common prefix when children exist.
- A recursion starved on quota before listing a deferred subtree returned
  without truncation, dropping keys silently; the block now reports a
  resumable truncation when the subtree still holds entries.
- Clone prefix-object entries with proto.Clone rather than copying the
  protobuf message by value.

* s3: close the hasEntries probe stream on return

* s3: resume delimited listings at the dir block boundary

A deferred directory block emits at its "<name>/" position, but emitDir
left nextMarker at the bare name, which sorts inside the (name, name/)
band and reads as "block pending". Every pass of the listing loop then
re-emitted the same common prefix until maxKeys ran out (999 prefixes,
IsTruncated), and a "<name>/" continuation token trimmed to "<name>" by
adjustMarkerForDelimiter reopened the block and paged forever.

Advance nextMarker to the block boundary the same way the recursive
branch does, and keep a "/" -ending marker intact — it already names the
bound past the block.

Chris Lu 8c55425d55 s3tables: tighten legacy OIDC subject re-anchoring (#11808)
* sts: recognize issuer-scoped parent user ids

ComputeParentUser output has a fixed shape (base64url SHA-256); let
callers distinguish it from bare subject strings.

* s3tables: keep legacy owner re-anchoring off local and scoped account ids

Re-anchoring a stored bare subject under the single trusted issuer must
only apply to strings that could actually be a legacy OIDC subject. A
stored owner naming the reserved or a configured local account, or an
already issuer-scoped id, can otherwise be claimed by any caller whose
token asserts that string as sub.

* s3tables: re-anchor legacy policy principals in map and array forms

A stored bare subject can appear as {"AWS": sub} or inside a principal
list, not only as a top-level string; re-anchoring only the string form
left legacy Deny statements unable to match the caller.

* s3tables: keep built-in legacy exclusions independent of the account checker

A missing local-account predicate must not disable re-anchoring entirely:
the reserved accounts, ARN-shaped values, and scoped-id shapes are never
OIDC subjects regardless, while legacy Deny statements for plain subjects
still need to resolve so a denied caller cannot fall through to an
identity grant.

* s3tables: exercise legacy Deny against an owner grant

The previous case denied the caller regardless of whether the statement
principal matched; make the caller the owner so a missed match shows.
Cover the array Deny form alongside the AWS map.

* s3api: recheck condition under lock when routed filer ignores condition_alt_key

A filer that predates condition_alt_key silently drops the field and
evaluates a suspended-versioning condition against the empty null slot
alone, so a matching If-Match still gets a false 412. Recheck under the
object lock instead of trusting that response: the lock path resolves the
same entry the read path serves. Genuine precondition failures still
return 412 from the recheck.

* s3api: cover suspended If-Match against a filer ignoring condition_alt_key

* s3api: resend against the resolved entry instead of the lock-path recheck

Rechecking under the gateway object lock does not serialize against
routed writers, which commit under the filer's path lock; a concurrent
routed PUT could land between the recheck and the create and be
overwritten with a stale precondition. Resend the same transaction with
condition_key set to the resolved version file so the condition and the
write stay under the same filer lock. When the resolved entry is the
null slot, a delete marker, or unresolvable, the resend targets the
object path and fails closed.

Chris Lu e6a0534e3b s3api: make ambiguous routed-PUT recovery atomic and stop transaction replay (#11787)
* filer_pb: map PRECONDITION_FAILED to a sentinel error

A conditional CreateEntry that the owner's path lock refuses comes back as
FilerError_PRECONDITION_FAILED; mapping it to ErrPreconditionFailed lets the
S3 gateway tell a rejected precondition apart from a transport failure and
report 412 instead of retrying the write.

* s3api: make the ambiguous-PUT recovery create conditional under the lock

createAfterAmbiguousRoute verified state and then issued an unconditional
create, so a write landing between the lookup and the create was still
clobbered by the stale re-commit (issue #11631). The recovery create now
carries a WriteCondition — IF_NOT_EXISTS for a proven-absent entry,
IF_ENTRY_EQUAL for a directory it may need to write onto — which the owner
filer evaluates under its per-path lock, making the check and the write
atomic. A refused precondition loops back to re-read the state instead of
overwriting whatever won the race.

* s3api: do not fail over a routed transaction past a possibly-sent request

withFilerClientFailover retried the callback on the next filer on any
transport error, so an ObjectTransaction whose response was lost could be
re-applied over a write that committed in between (issue #11631). A gRPC
error cannot distinguish "never sent" from "committed", but channel
readiness can: a non-replayable callback now runs only on a connection that
just reached READY, and failover continues only over channels that never
came up — the one failure mode that provably sent nothing.

* s3api: run ambiguous-route recovery for empty PUTs too

The recovery was gated on a nonempty chunk list, so a zero-byte PUT whose
routed transaction lost its response still fell back to an unconditional
create that could overwrite a newer write and delete its chunks. Chunk-count
mismatch on an empty upload list is enough to distinguish a superseding
entry from this PUT's — there is nothing to save by skipping the check.

* s3api: keep conditional recovery creates off the replay path

The conditional create in the ambiguous-PUT fallback rode the replayable
WithFilerClient failover, so a committed create whose response was lost
could be re-sent to another filer — where a delete in between would let
IF_NOT_EXISTS pass again and resurrect an entry pointing at reclaimed
chunks. Conditional creates now run through the non-replayable failover;
an ambiguous result falls through to confirmCreateLanded, which resolves
the committed entry rather than resending.

* s3api: do not mark a filer unhealthy for an answered request

A reply that reached the callback — including an application-level failure
like a refused write precondition — proves the filer is alive. Checking
received before the health bookkeeping keeps definitive application errors
from tripping the failure circuit or flagging a live routed owner as
unreachable.

* s3api: do not claim an empty stored entry as an ambiguous PUT's own

Two chunkless entries compare equal under sameFileChunks, so an older
empty object satisfies "the route landed" even though it predates this
write — recovery would return success while leaving the request's
Content-Type and metadata unapplied. A landed PUT stores the entry
exactly as built, so require mime/size/md5/content and the extended
attributes to match before claiming it; anything else stays uncertain
and the client retries.

* s3api: prove ambiguous empty PUTs by write id and pin recovery to the owner

- Conditional recovery creates are sent to the routed owner alone instead of failing over: the condition only serializes with routed writes under the owner's per-path lock, and another filer's forwarding is only as correct as its ring view. An unreachable owner now yields an uncertain result rather than a create under a different serialization boundary.
- A proven-absent path no longer satisfies an empty, chunkless PUT: the routed commit may have landed and been deleted, and there are no chunks to verify, so IF_NOT_EXISTS could resurrect a removed object. Recovery returns uncertain for the client to retry.
- Chunkless identity moves from metadata equality to a per-write id (x-seaweedfs-write-id) stamped into Extended: an identical older object can match mime/md5/content but not the id. Entries without this write's id are not claimed, and confirmCreateLanded can now positively confirm a committed empty object instead of always reporting failure.

Chris Lu 44bb697495 s3api: hydrate runtime policies on propagated IAM updates (#11784)
* s3api: hydrate runtime policies on pushed identity upserts

PutIdentity propagation (used on every IAM write when the credential
store has a master client) carries the persisted identity proto. That
proto records inline policies only as flattened legacy Actions; their
runtime __inline_policy__ names live in the policy store and were
dropped by the merge. For the interval until the next full reload, an
identity whose policy denied e.g. DeleteObject routed to legacy
CanDo, where "Write:bucket" authorizes deletes.

Hydrate the pushed identity the same way a full load does, so the
merged state always carries its runtime policy names and documents.

* s3api: hydrate runtime policies on pushed group upserts

PutGroup propagation has the same gap as identity pushes: the wire
proto does not carry the group's runtime __inline_group_policy__ names,
so members' attached-policy check lost them until the next reload.

* s3api: attach only runtime inline policy names on pushes

Listing the pushed identity's or group's own inline policies is enough
to keep it on the attached-policy route; a whole-store hydration per
pushed proto is not. Pushes now never write iam.policies, so a stale
read can no longer overwrite a newer committed policy document.

* s3api: carry inline policy documents on pushed upserts

Attaching only runtime policy names left a window where a pushed identity or group referenced a document the local cache had never loaded, denying allowed requests until the next reload. Fetch the pushed entity own inline documents and publish them with the update; reads stay scoped to the pushed entity rather than the whole store, and inline runtime names are only ever populated from this store so a read cannot install a document older than the committed one. Resync the IAM manager only when a push actually installs documents.

* s3api: order pushed inline policy reads against their installs

A pushed UpsertIdentity or PutGroup read inline policy documents from
the credential store and installed them without holding the ordering
guard that full reloads already take, so a delayed push could overwrite
a newer committed document with its stale read and restore a revoked
grant until the next update or reload.

Pushes now hold reloadMu across the store read and the install, the same
snapshot-through-commit serialization the credential-manager load uses.
MergeS3ApiConfiguration also applies config.Policies to the live
iam.policies at commit instead of swapping in its earlier snapshot, so a
policy installed while a merge prepared (a pushed inline document or a
PutPolicy update) is no longer discarded.

74ed12d6b3 s3 lifecycle: replay only the rules that fit the retention window (#11789)
* s3 lifecycle: replay only the rules that fit the retention window

runShard handed drainShardEvents the full snapshot, so rules the retention
window assigns to the walk were also matched during meta-log replay. Their
matches are not due yet, and drainShardEvents freezes the cursor at the first
event with a not-yet-due match. With a 3-day and a 30-day expiration rule on one
bucket and RetentionWindow of 8 days, every shard's cursor stopped at the first
30-day object's PUT and stayed there until that object came due. Each pass
then re-read the log from that point and re-dispatched every 3-day expiration
already handled, which surfaces as NOOP_RESOLVED dispatches, a growing
cursor_lag_max, and passes that still report status=ok.

Snapshot.ReplayView drops the replay-kind actions promoted to the walk and
keeps every other action as compiled, and the drain uses it. Promoted rules
are served by the walk as before. RulesForShard, PromotedHash and ReplayView
share one isPromoted predicate. With RetentionWindow unset no active rule is
promoted, so behaviour without a configured window is unchanged.

* s3 lifecycle: scale the replay-view test with DaysToDuration

The test took its retention window from DaysToDuration but dated its PUTs
in hours, so under the s3tests build tag (one lifecycle day = 10s) every
event fell before the seeded cursor and replay never ran. Express the
event ages in DaysToDuration too, so the test exercises replay at both
scales.

* s3 lifecycle: rehabilitate scan_only mode in the replay drain view

ReplayView shared the base CompiledAction pointers, so a replay-kind
rule locked into ModeScanOnly by a prior compile stayed invisible to
router.Route's event_driven gate even when the runtime retention window
kept it in the replay partition - and it is absent from the walk view
too, so the rule would be served by neither.

Clone non-promoted replay-kind actions the way RulesForShard does
(Mode forced to event_driven), reactivating the scan_only case whose
bootstrap rendezvous already completed, while preserving the base
active bit for genuinely pre-bootstrap actions. Disabled actions are
excluded for parity with the other views, and DESIGN.md now documents
the view.

* s3 lifecycle: keep drain activation observable, require walker with retention

ReplayView now shares pointers for event-driven actions so a mid-pass
MarkActive flip remains visible to the drain; only a scan_only-locked
action is cloned to event_driven, and reactivated only when its
bootstrap rendezvous completed (tracked via a new bootstrapComplete
field on CompiledAction).

validate() rejects RetentionWindow without Walker: promoted rules
would lose their only dispatch path while the drain cursor still
advanced past their events.

The daily pass invoked the walker once per shard, and every shard's
walk listed the full bucket tree while keeping only its own 1/16 of
the entries — 16 full listings per pass by default (#11791).

Run now groups the shards by the walk branch they'll take (recovery
vs steady, using the same cursor data and hash checks runShard applies)
and starts one shared walk per group, so a pass lists each bucket at
most twice. WalkerFunc and WalkBuckets take a shard set instead of a
single shard. runShard keeps its own decision and waits on its group's
walk; a shard whose freshly-loaded cursor disagrees with the plan falls
back to a per-shard walk, so mid-pass cursor rewrites can't under-cover
a shard.

* s3 lifecycle: skip the .versions/ pre-pass on non-versioned buckets

walkBucketTree listed every directory twice — once looking for
.versions/ dirs, once for regular entries. On a bucket that never had
versioning enabled the first pass can only find coincidentally-named
user folders, so the extra listing is pure cost (#11791).

FilerListFunc now takes the walk view and consults
Snapshot.BucketVersioned; non-versioned buckets skip pass 1 entirely.
A *-suffixed .versions user folder on such a bucket is recursed into
as a regular directory so real objects inside still surface; a nil
view keeps the two-pass behavior.

* s3 lifecycle: prune walk directories to active rule prefixes

The daily walk listed every directory under a bucket even when no
rule prefix could reach it. Collect the active rule prefixes of each
bucket from the walk view (new Snapshot.BucketPrefixes) and skip
recursing into directories whose keys can never match; a bucket
with no active actions is skipped entirely, saving the listing.

.uploads stays in scope regardless of prefixes because AbortMPU
rules match DestKey, and .versions expansion is pruned only
conservatively (the logical key is a string-prefix of the dir key).

* s3 lifecycle: join planned walks before Run returns

planWalks starts a shared walk goroutine per group, but a shard whose
authoritative cursor load then fails exits runShard without waiting on
it. Run returned while the walk still listed or dispatched deletes
against connections the caller closes on return. Join every planned
walk after the shard waitgroup.

* s3 lifecycle: treat object-locked buckets as versioned in the walk

Object Lock requires versioning and every writer sets both extended
attributes, but IsBucketVersioned only read ExtVersioningKey. A locked
bucket missing that attribute would have its .versions dirs walked as
ordinary folders, hiding version siblings from lifecycle. Classify
ExtObjectLockEnabledKey as versioned too.

Chris Lu 42ff7f2b8e s3: report an empty probed directory as a common prefix, not a key (#11779)
The "<dir>/" existence probe emitted the empty directory as a
FolderMimeType Contents entry, so delimited listings returned a fake
readable key that breaks clients treating every key as an object.
Delimited probes now report the directory as a CommonPrefix -- which
the probe accepts for existence -- while the recursive (no delimiter)
probe keeps the directory marker.
