Chris Lu 3b9e196e5f sts: enforce session-policy explicit deny during role chaining (#10103)
* sts: enforce session-policy explicit deny during role chaining

A chained AssumeRole caller authenticates with an STS session token whose
inline session policy can explicitly deny sts:AssumeRole. The deny check only
evaluated the caller's named policies, so such a session could still chain into
any role its trust policy admits. Validate the session token in the deny check
and honor an explicit Deny in the inline session policy too.

* test(sts): integration coverage for AssumeRole authorization

Add an end-to-end AssumeRole authorization test (real weed mini + boto3):
a non-admin caller assumes a role its trust policy admits, an explicit
identity-side deny is blocked, and a session policy's explicit deny blocks
role chaining.

* sts: skip OIDC tokens and reject revoked sessions in the chaining deny check

Review follow-ups on the session-policy deny check:
- Guard session validation with !isOIDCToken so a bearer token our STS service
  cannot validate does not error into a false deny.
- Reject a revoked session before evaluating its policy, restoring the
  revocation enforcement the AssumeRole path lost when it stopped routing
  through IsActionAllowed.

Chris Lu fbe758efa8 test: consolidate port allocation into shared test/testutil package (#8982)
* test: consolidate port allocation into shared test/testutil package

Move duplicated port allocation logic from 15+ test files into a single
shared package at test/testutil/. This fixes a port collision bug where
independently allocated ports could overlap via the gRPC offset
(port+10000), causing weed mini to reject the configuration.

The shared package provides:
- AllocatePorts: atomic allocation of N unique ports
- AllocateMiniPorts/MustFreeMiniPorts: gRPC-offset-aware allocation
  that prevents port A+10000 == port B collisions
- WaitForPort, WaitForService, FindBindIP, WriteIAMConfig, HasDocker

* test: address review feedback and fix FUSE build

- Revert fuse_integration change: it has its own go.mod and cannot
  import the shared testutil package
- AllocateMiniPorts: hold all listeners open until the entire batch is
  allocated, preventing race conditions where other processes steal ports
- HasDocker: add 5s context timeout to avoid hanging on stalled Docker
- WaitForService: only treat 2xx HTTP status codes as ready

* test: use global rand in AllocateMiniPorts for better seeding

Go 1.20+ auto-seeds the global rand generator. Using it avoids
identical sequences when multiple tests call at the same nanosecond.

* test: revert WaitForService status code check

S3 endpoints return non-2xx (e.g. 403) on bare GET requests, so
requiring 2xx caused the S3 integration test to time out. Any HTTP
response is sufficient proof that the service is running.

* test: fix gofmt formatting in s3tables test files

Chris Lu e7fc243ee1 Fix flaky s3tables tests: allocate all ports atomically
The test port allocation had a TOCTOU race where GetFreePort() would
open a listener, grab the port number, then immediately close it.
When called repeatedly, the OS could recycle a just-released port,
causing two services (e.g. Filer and S3) to be assigned the same port.

Replace per-call GetFreePort() with batch AllocatePorts() that holds
all listeners open until every port is obtained, matching the pattern
already used in test/volume_server/framework/cluster.go.

Chris Lu 49a64f50f1 Add session policy support to IAM (#8338)
* Add session policy support to IAM

- Implement policy evaluation for session tokens in policy_engine.go
- Add session_policy field to session claims for tracking applied policies
- Update STS service to include session policies in token generation
- Add IAM integration tests for session policy validation

* sts: support inline session policies for AssumeRoleWithWebIdentity and credential-based flows

* s3api: parse and normalize Policy parameter for STS HTTP handlers

* tests: add session policy unit tests and integration tests for inline policy downscoping

* tests: add s3tables STS inline policy integration

* iam: handle user principals and validate tokens

* sts: enforce inline session policy size limit

* tests: harden s3tables STS integration config

* iam: clarify principal policy resolution errors

* tests: improve STS integration endpoint selection

Chris Lu c1a9263e37 Fix STS AssumeRole with POST body param (#8320)
* Fix STS AssumeRole with POST body param and add integration test

* Add STS integration test to CI workflow

* Address code review feedback: fix HPP vulnerability and style issues

* Refactor: address code review feedback

- Fix HTTP Parameter Pollution vulnerability in UnifiedPostHandler
- Refactor permission check logic for better readability
- Extract test helpers to testutil/docker.go to reduce duplication
- Clean up imports and simplify context setting

* Add SigV4-style test variant for AssumeRole POST body routing

- Added ActionInBodyWithSigV4Style test case to validate real-world scenario
- Test confirms routing works correctly for AWS SigV4-signed requests
- Addresses code review feedback about testing with SigV4 signatures

* Fix: always set identity in context when non-nil

- Ensure UnifiedPostHandler always calls SetIdentityInContext when identity is non-nil
- Only call SetIdentityNameInContext when identity.Name is non-empty
- This ensures downstream handlers (embeddedIam.DoActions) always have access to identity
- Addresses potential issue where empty identity.Name would skip context setting
