This PR fixes
- allow 's3:versionid` as a valid conditional for
Get,Put,Tags,Object locking APIs
- allow additional headers missing for object APIs
- allow wildcard based action matching
s3:HardwareInfo was removed recently. Users having that admin action
stored in the backend will have an issue starting the server.
To fix this, we need to avoid returning an error in Marshal/Unmarshal
when they encounter an invalid action and validate only in specific
location.
Currently the validation is done and in ParseConfig().
This PR introduces two new features
- AWS STS compatible STS API named AssumeRoleWithClientGrants
```
POST /?Action=AssumeRoleWithClientGrants&Token=<jwt>
```
This API endpoint returns temporary access credentials, access
tokens signature types supported by this API
- RSA keys
- ECDSA keys
Fetches the required public key from the JWKS endpoints, provides
them as rsa or ecdsa public keys.
- External policy engine support, in this case OPA policy engine
- Credentials are stored on disks
- remove old bucket policy handling
- add new policy handling
- add new policy handling unit tests
This patch brings support to bucket policy to have more control not
limiting to anonymous. Bucket owner controls to allow/deny any rest
API.
For example server side encryption can be controlled by allowing
PUT/GET objects with encryptions including bucket owner.
