blitt001	3d81d5bef7	Fix S3 signature verification behind reverse proxies (#8444 ) * Fix S3 signature verification behind reverse proxies When SeaweedFS is deployed behind a reverse proxy (e.g. nginx, Kong, Traefik), AWS S3 Signature V4 verification fails because the Host header the client signed with (e.g. "localhost:9000") differs from the Host header SeaweedFS receives on the backend (e.g. "seaweedfs:8333"). This commit adds a new -s3.externalUrl parameter (and S3_EXTERNAL_URL environment variable) that tells SeaweedFS what public-facing URL clients use to connect. When set, SeaweedFS uses this host value for signature verification instead of the Host header from the incoming request. New parameter: -s3.externalUrl (flag) or S3_EXTERNAL_URL (environment variable) Example: -s3.externalUrl=http://localhost:9000 Example: S3_EXTERNAL_URL=https://s3.example.com The environment variable is particularly useful in Docker/Kubernetes deployments where the external URL is injected via container config. The flag takes precedence over the environment variable when both are set. At startup, the URL is parsed and default ports are stripped to match AWS SDK behavior (port 80 for HTTP, port 443 for HTTPS), so "http://s3.example.com:80" and "http://s3.example.com" are equivalent. Bugs fixed: - Default port stripping was removed by a prior PR, causing signature mismatches when clients connect on standard ports (80/443) - X-Forwarded-Port was ignored when X-Forwarded-Host was not present - Scheme detection now uses proper precedence: X-Forwarded-Proto > TLS connection > URL scheme > "http" - Test expectations for standard port stripping were incorrect - expectedHost field in TestSignatureV4WithForwardedPort was declared but never actually checked (self-referential test) * Add Docker integration test for S3 proxy signature verification Docker Compose setup with nginx reverse proxy to validate that the -s3.externalUrl parameter (or S3_EXTERNAL_URL env var) correctly resolves S3 signature verification when SeaweedFS runs behind a proxy. The test uses nginx proxying port 9000 to SeaweedFS on port 8333, with X-Forwarded-Host/Port/Proto headers set. SeaweedFS is configured with -s3.externalUrl=http://localhost:9000 so it uses "localhost:9000" for signature verification, matching what the AWS CLI signs with. The test can be run with aws CLI on the host or without it by using the amazon/aws-cli Docker image with --network host. Test covers: create-bucket, list-buckets, put-object, head-object, list-objects-v2, get-object, content round-trip integrity, delete-object, and delete-bucket — all through the reverse proxy. * Create s3-proxy-signature-tests.yml * fix CLI * fix CI * Update s3-proxy-signature-tests.yml * address comments * Update Dockerfile * add user * no need for fuse * Update s3-proxy-signature-tests.yml * debug * weed mini * fix health check * health check * fix health checking --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Chris Lu <chris.lu@gmail.com>	3 days ago
Chris Lu	0d8588e3ae	S3: Implement IAM defaults and STS signing key fallback (#8348 ) * S3: Implement IAM defaults and STS signing key fallback logic * S3: Refactor startup order to init SSE-S3 key manager before IAM * S3: Derive STS signing key from KEK using HKDF for security isolation * S3: Document STS signing key fallback in security.toml * fix(s3api): refine anonymous access logic and secure-by-default behavior - Initialize anonymous identity by default in `NewIdentityAccessManagement` to prevent nil pointer exceptions. - Ensure `ReplaceS3ApiConfiguration` preserves the anonymous identity if not present in the new configuration. - Update `NewIdentityAccessManagement` signature to accept `filerClient`. - In legacy mode (no policy engine), anonymous defaults to Deny (no actions), preserving secure-by-default behavior. - Use specific `LookupAnonymous` method instead of generic map lookup. - Update tests to accommodate signature changes and verify improved anonymous handling. * feat(s3api): make IAM configuration optional - Start S3 API server without a configuration file if `EnableIam` option is set. - Default to `Allow` effect for policy engine when no configuration is provided (Zero-Config mode). - Handle empty configuration path gracefully in `loadIAMManagerFromConfig`. - Add integration test `iam_optional_test.go` to verify empty config behavior. * fix(iamapi): fix signature mismatch in NewIdentityAccessManagementWithStore * fix(iamapi): properly initialize FilerClient instead of passing nil * fix(iamapi): properly initialize filer client for IAM management - Instead of passing `nil`, construct a `wdclient.FilerClient` using the provided `Filers` addresses. - Ensure `NewIdentityAccessManagementWithStore` receives a valid `filerClient` to avoid potential nil pointer dereferences or limited functionality. * clean: remove dead code in s3api_server.go * refactor(s3api): improve IAM initialization, safety and anonymous access security * fix(s3api): ensure IAM config loads from filer after client init * fix(s3): resolve test failures in integration, CORS, and tagging tests - Fix CORS tests by providing explicit anonymous permissions config - Fix S3 integration tests by setting admin credentials in init - Align tagging test credentials in CI with IAM defaults - Added goroutine to retry IAM config load in iamapi server * fix(s3): allow anonymous access to health targets and S3 Tables when identities are present * fix(ci): use /healthz for Caddy health check in awscli tests * iam, s3api: expose DefaultAllow from IAM and Policy Engine This allows checking the global "Open by Default" configuration from other components like S3 Tables. * s3api/s3tables: support DefaultAllow in permission logic and handler Updated CheckPermissionWithContext to respect the DefaultAllow flag in PolicyContext. This enables "Open by Default" behavior for unauthenticated access in zero-config environments. Added a targeted unit test to verify the logic. * s3api/s3tables: propagate DefaultAllow through handlers Propagated the DefaultAllow flag to individual handlers for namespaces, buckets, tables, policies, and tagging. This ensures consistent "Open by Default" behavior across all S3 Tables API endpoints. * s3api: wire up DefaultAllow for S3 Tables API initialization Updated registerS3TablesRoutes to query the global IAM configuration and set the DefaultAllow flag on the S3 Tables API server. This completes the end-to-end propagation required for anonymous access in zero-config environments. Added a SetDefaultAllow method to S3TablesApiServer to facilitate this. * s3api: fix tests by adding DefaultAllow to mock IAM integrations The IAMIntegration interface was updated to include DefaultAllow(), breaking several mock implementations in tests. This commit fixes the build errors by adding the missing method to the mocks. * env * ensure ports * env * env * fix default allow * add one more test using non-anonymous user * debug * add more debug * less logs	2 weeks ago
