ad89f003a5 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.

* 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.

* 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.

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.

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.

25f36cd13d fix(s3api): require space in v2 auth prefix (#9852)
* fix(s3api): require space in v2 auth prefix

Problem: Signature V2 Authorization headers with a malformed algorithm token such as AWSX... are accepted as if they were AWS ... headers.

Root cause: validateV2AuthHeader checks HasPrefix("AWS") but then slices past an assumed trailing space, so an extra character after AWS is skipped and the rest is parsed as credentials.

Fix: Require the Authorization header to start with the exact AWS plus space prefix before parsing fields.

Reproduction: go test ./weed/s3api -run 'TestValidateV2AuthHeader/algorithm_prefix_without_space|TestDoesSignV2Match/malformed_auth_-_no_space_after_AWS' -count=1 fails before the fix because AWSXAKIA... is accepted.

Validation: go test ./weed/s3api -run 'TestValidateV2AuthHeader/algorithm_prefix_without_space|TestDoesSignV2Match/malformed_auth_-_no_space_after_AWS' -count=1; go test ./weed/s3api -count=1; git diff --check; git diff --cached --check

Chris Lu ae9a943ef6 IAM: Add Service Account Support (#7744) (#7901)
* iam: add ServiceAccount protobuf schema

Add ServiceAccount message type to iam.proto with support for:
- Unique ID and parent user linkage
- Optional expiration timestamp
- Separate credentials (access key/secret)
- Action restrictions (subset of parent)
- Enable/disable status

This is the first step toward implementing issue #7744
(IAM Service Account Support).

* iam: add service account response types

Add IAM API response types for service account operations:
- ServiceAccountInfo struct for marshaling account details
- CreateServiceAccountResponse
- DeleteServiceAccountResponse
- ListServiceAccountsResponse
- GetServiceAccountResponse
- UpdateServiceAccountResponse

Also add type aliases in iamapi package for backwards compatibility.

Part of issue #7744 (IAM Service Account Support).

* iam: implement service account API handlers

Add CRUD operations for service accounts:
- CreateServiceAccount: Creates service account with ABIA key prefix
- DeleteServiceAccount: Removes service account and parent linkage
- ListServiceAccounts: Lists all or filtered by parent user
- GetServiceAccount: Retrieves service account details
- UpdateServiceAccount: Modifies status, description, expiration

Service accounts inherit parent user's actions by default and
support optional expiration timestamps.

Part of issue #7744 (IAM Service Account Support).

* sts: add AssumeRoleWithWebIdentity HTTP endpoint

Add STS API HTTP endpoint for AWS SDK compatibility:
- Create s3api_sts.go with HTTP handlers matching AWS STS spec
- Support AssumeRoleWithWebIdentity action with JWT token
- Return XML response with temporary credentials (AccessKeyId,
  SecretAccessKey, SessionToken) matching AWS format
- Register STS route at POST /?Action=AssumeRoleWithWebIdentity

This enables AWS SDKs (boto3, AWS CLI, etc.) to obtain temporary
S3 credentials using OIDC/JWT tokens.

Part of issue #7744 (IAM Service Account Support).

* test: add service account and STS integration tests

Add integration tests for new IAM features:

s3_service_account_test.go:
- TestServiceAccountLifecycle: Create, Get, List, Update, Delete
- TestServiceAccountValidation: Error handling for missing params

s3_sts_test.go:
- TestAssumeRoleWithWebIdentityValidation: Parameter validation
- TestAssumeRoleWithWebIdentityWithMockJWT: JWT token handling

Tests skip gracefully when SeaweedFS is not running or when IAM
features are not configured.

Part of issue #7744 (IAM Service Account Support).

* iam: address code review comments

- Add constants for service account ID and key lengths
- Use strconv.ParseInt instead of fmt.Sscanf for better error handling
- Allow clearing descriptions by checking key existence in url.Values
- Replace magic numbers (12, 20, 40) with named constants

Addresses review comments from gemini-code-assist[bot]

* test: add proper error handling in service account tests

Use require.NoError(t, err) for io.ReadAll and xml.Unmarshal
to prevent silent failures and ensure test reliability.

Addresses review comment from gemini-code-assist[bot]

* test: add proper error handling in STS tests

Use require.NoError(t, err) for io.ReadAll and xml.Unmarshal
to prevent silent failures and ensure test reliability.
Repeated this fix throughout the file.

Addresses review comment from gemini-code-assist[bot] in PR #7901.

* iam: address additional code review comments

- Specific error code mapping for STS service errors
- Distinguish between Sender and Receiver error types in STS responses
- Add nil checks for credentials in List/GetServiceAccount
- Validate expiration date is in the future
- Improve integration test error messages (include response body)
- Add credential verification step in service account tests

Addresses remaining review comments from gemini-code-assist[bot] across multiple files.

* iam: fix shared slice reference in service account creation

Copy parent's actions to create an independent slice for the service
account instead of sharing the underlying array. This prevents
unexpected mutations when the parent's actions are modified later.

Addresses review comment from coderabbitai[bot] in PR #7901.

* iam: remove duplicate unused constant

Removed redundant iamServiceAccountKeyPrefix as ServiceAccountKeyPrefix
is already defined and used.

Addresses remaining cleanup task.

* sts: document limitation of string-based error mapping

Added TODO comment explaining that the current string-based error
mapping approach is fragile and should be replaced with typed errors
from the STS service in a future refactoring.

This addresses the architectural concern raised in code review while
deferring the actual implementation to a separate PR to avoid scope
creep in the current service account feature addition.

* iam: fix remaining review issues

- Add future-date validation for expiration in UpdateServiceAccount
- Reorder tests so credential verification happens before deletion
- Fix compilation error by using correct JWT generation methods

Addresses final review comments from coderabbitai[bot].

* iam: fix service account access key length

The access key IDs were incorrectly generated with 24 characters
instead of the AWS-standard 20 characters. This was caused by
generating 20 random characters and then prepending the 4-character
ABIA prefix.

Fixed by subtracting the prefix length from AccessKeyLength, so the
final key is: ABIA (4 chars) + random (16 chars) = 20 chars total.

This ensures compatibility with S3 clients that validate key length.

* test: add comprehensive service account security tests

Added comprehensive integration tests for service account functionality:

- TestServiceAccountS3Access: Verify SA credentials work for S3 operations
- TestServiceAccountExpiration: Test expiration date validation and enforcement
- TestServiceAccountInheritedPermissions: Verify parent-child relationship
- TestServiceAccountAccessKeyFormat: Validate AWS-compatible key format (ABIA prefix, 20 char length)

These tests ensure SeaweedFS service accounts are compatible with AWS
conventions and provide robust security coverage.

* iam: remove unused UserAccessKeyPrefix constant

Code cleanup to remove unused constants.

* iam: remove unused iamCommonResponse type alias

Code cleanup to remove unused type aliases.

* iam: restore and use UserAccessKeyPrefix constant

Restored UserAccessKeyPrefix constant and updated s3api tests to use it
instead of hardcoded strings for better maintainability and consistency.

* test: improve error handling in service account security tests

Added explicit error checking for io.ReadAll and xml.Unmarshal in
TestServiceAccountExpiration to ensure failures are reported correctly and
cleanup is performed only when appropriate. Also added logging for failed
responses.

* test: use t.Cleanup for reliable resource cleanup

Replaced defer with t.Cleanup to ensure service account cleanup runs even
when require.NoError fails. Also switched from manual error checking to
require.NoError for more idiomatic testify usage.

* iam: add CreatedBy field and optimize identity lookups

- Added createdBy parameter to CreateServiceAccount to track who created each service account
- Extract creator identity from request context using GetIdentityNameFromContext
- Populate created_by field in ServiceAccount protobuf
- Added findIdentityByName helper function to optimize identity lookups
- Replaced nested loops with O(n) helper function calls in CreateServiceAccount and DeleteServiceAccount

This addresses code review feedback for better auditing and performance.

* iam: prevent user deletion when service accounts exist

Following AWS IAM behavior, prevent deletion of users that have active
service accounts. This ensures explicit cleanup and prevents orphaned
service account resources with invalid ParentUser references.

Users must delete all associated service accounts before deleting the
parent user, providing safer resource management.

* sts: enhance TODO with typed error implementation guidance

Updated TODO comment with detailed implementation approach for replacing
string-based error matching with typed errors using errors.Is(). This
provides a clear roadmap for a follow-up PR to improve error handling
robustness and maintainability.

* iam: add operational limits for service account creation

Added AWS IAM-compatible safeguards to prevent resource exhaustion:
- Maximum 100 service accounts per user (LimitExceededException)
- Maximum 1000 character description length (InvalidInputException)

These limits prevent accidental or malicious resource exhaustion while
not impacting legitimate use cases.

* iam: add missing operational limit constants

Added MaxServiceAccountsPerUser and MaxDescriptionLength constants that
were referenced in the previous commit but not defined.

* iam: enforce service account expiration during authentication

CRITICAL SECURITY FIX: Expired service account credentials were not being
rejected during authentication, allowing continued access after expiration.

Changes:
- Added Expiration field to Credential struct
- Populate expiration when loading service accounts from configuration
- Check expiration in all authentication paths (V2 and V4 signatures)
- Return ErrExpiredToken for expired credentials

This ensures expired service accounts are properly rejected at authentication
time, matching AWS IAM behavior and preventing unauthorized access.

* iam: fix error code for expired service account credentials

Use ErrAccessDenied instead of non-existent ErrExpiredToken for expired
service account credentials. This provides appropriate access denial for
expired credentials while maintaining AWS-compatible error responses.

* iam: fix remaining ErrExpiredToken references

Replace all remaining instances of non-existent ErrExpiredToken with
ErrAccessDenied for expired service account credentials.

* iam: apply AWS-standard key format to user access keys

Updated CreateAccessKey to generate AWS-standard 20-character access keys
with AKIA prefix for regular users, matching the format used for service
accounts. This ensures consistency across all access key types and full
AWS compatibility.

- Access keys: AKIA + 16 random chars = 20 total (was 21 chars, no prefix)
- Secret keys: 40 random chars (was 42, now matches AWS standard)
- Uses AccessKeyLength and UserAccessKeyPrefix constants

* sts: replace fragile string-based error matching with typed errors

Implemented robust error handling using typed errors and errors.Is() instead
of fragile strings.Contains() matching. This decouples the HTTP layer from
service implementation details and prevents errors from being miscategorized
if error messages change.

Changes:
- Added typed error variables to weed/iam/sts/constants.go:
  * ErrTypedTokenExpired
  * ErrTypedInvalidToken
  * ErrTypedInvalidIssuer
  * ErrTypedInvalidAudience
  * ErrTypedMissingClaims

- Updated STS service to wrap provider authentication errors with typed errors
- Replaced strings.Contains() with errors.Is() in HTTP layer for error checking
- Removed TODO comment as the improvement is now implemented

This makes error handling more maintainable and reliable.

* sts: eliminate all string-based error matching with provider-level typed errors

Completed the typed error implementation by adding provider-level typed errors
and updating provider implementations to return them. This eliminates ALL
fragile string matching throughout the entire error handling stack.

Changes:
- Added typed error definitions to weed/iam/providers/errors.go:
  * ErrProviderTokenExpired
  * ErrProviderInvalidToken
  * ErrProviderInvalidIssuer
  * ErrProviderInvalidAudience
  * ErrProviderMissingClaims

- Updated OIDC provider to wrap JWT validation errors with typed provider errors
- Replaced strings.Contains() with errors.Is() in STS service for error mapping
- Complete error chain: Provider -> STS -> HTTP layer, all using errors.Is()

This provides:
- Reliable error classification independent of error message content
- Type-safe error checking throughout the stack
- No order-dependent string matching
- Maintainable error handling that won't break with message changes

* oidc: use jwt.ErrTokenExpired instead of string matching

Replaced the last remaining string-based error check with the JWT library's
exported typed error. This makes the error detection independent of error
message content and more robust against library updates.

Changed from:
  strings.Contains(errMsg, "expired")
To:
  errors.Is(err, jwt.ErrTokenExpired)

This completes the elimination of ALL string-based error matching throughout
the entire authentication stack.

* iam: add description length validation to UpdateServiceAccount

Fixed inconsistency where UpdateServiceAccount didn't validate description
length against MaxDescriptionLength, allowing operational limits to be
bypassed during updates.

Now validates that updated descriptions don't exceed 1000 characters,
matching the validation in CreateServiceAccount.

* iam: refactor expiration check into helper method

Extracted duplicated credential expiration check logic into a helper method
to reduce code duplication and improve maintainability.

Added Credential.isCredentialExpired() method and replaced 5 instances of
inline expiration checks across auth_signature_v2.go and auth_signature_v4.go.

* iam: address critical Copilot security and consistency feedback

Fixed three critical issues identified by Copilot code review:

1. SECURITY: Prevent loading disabled service account credentials
   - Added check to skip disabled service accounts during credential loading
   - Disabled accounts can no longer authenticate

2. Add DurationSeconds validation for STS AssumeRoleWithWebIdentity
   - Enforce AWS-compatible range: 900-43200 seconds (15 min - 12 hours)
   - Returns proper error for out-of-range values

3. Fix expiration update consistency in UpdateServiceAccount
   - Added key existence check like Description field
   - Allows explicit clearing of expiration by setting to empty string
   - Distinguishes between "not updating" and "clearing expiration"

* sts: remove unused durationSecondsStr variable

Fixed build error from unused variable after refactoring duration parsing.

* iam: address remaining Copilot feedback and remove dead code

Completed remaining Copilot code review items:

1. Remove unused getPermission() method (dead code)
   - Method was defined but never called anywhere

2. Improve slice modification safety in DeleteServiceAccount
   - Replaced append-with-slice-operations with filter pattern
   - Avoids potential issues from mutating slice during iteration

3. Fix route registration order
   - Moved STS route registration BEFORE IAM route
   - Prevents IAM route from intercepting STS requests
   - More specific route (with query parameter) now registered first

* iam: improve expiration validation and test cleanup robustness

Addressed additional Copilot feedback:

1. Make expiration validation more explicit
   - Added explicit check for negative values
   - Added comment clarifying that 0 is allowed to clear expiration
   - Improves code readability and intent

2. Fix test cleanup order in s3_service_account_test.go
   - Track created service accounts in a slice
   - Delete all service accounts before deleting parent user
   - Prevents DeleteConflictException during cleanup
   - More robust cleanup even if test fails mid-execution

Note: s3_service_account_security_test.go already had correct cleanup
order due to LIFO defer execution.

* test: remove redundant variable assignments

Removed duplicate assignments of createdSAId, createdAccessKeyId, and
createdSecretAccessKey on lines 148-150 that were already assigned on
lines 132-134.
