This commit fixes a regression introduced in f187a16962
the regression returned AccessDenied when a client is trying to create an empty
directory on a existing prefix, though it should return 200 OK to be close as
much as possible to S3 specification.
Since refactoring to GetObjectNInfo style, there are many cases
when i/o closed pipe is printed like, downloading an object
with wrong encryption key. This PR removes the log.
This commit moves the check that SSE-C requests
must be made over TLS into a generic HTTP handler.
Since the HTTP server uses custom TCP connection handling
it is not possible to use `http.Request.TLS` to check
for TLS connections. So using `globalIsSSL` is the only
option to detect whether the request is made over TLS.
By extracting this check into a separate handler it's possible
to refactor other parts of the SSE handling code further.
This commit adds two functions for sealing/unsealing the
etag (a.k.a. content MD5) in case of SSE single-part upload.
Sealing the ETag is neccessary in case of SSE-S3 to preserve
the security guarantees. In case of SSE-S3 AWS returns the
content-MD5 of the plaintext object as ETag. However, we
must not store the MD5 of the plaintext for encrypted objects.
Otherwise it becomes possible for an attacker to detect
equal/non-equal encrypted objects. Therefore we encrypt
the ETag before storing on the backend. But we only need
to encrypt the ETag (content-MD5) if the client send it -
otherwise the client cannot verify it anyway.
CopyObject handler forgot to remove multipart encryption flag in metadata
when source is an encrypted multipart object and the target is also encrypted
but single part object.
This PR also simplifies the code to facilitate review.
This PR brings an additional logger implementation
called AuditLog which logs to http targets
The intention is to use AuditLog to log all incoming
requests, this is used as a mechanism by external log
collection entities for processing Minio requests.
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
- Only require len(disks)/2 to initialize the cluster
- Fix checking of read/write quorm in subsystems init
- Add retry mechanism in policy and notification to avoid aborting in case of read/write quorums errors
in xl.PutObjectPart call, prepareFile detected an error when the storage
is exhausted but we were returning the wrong error.
With this commit, users can see the correct error message when their disks
become full.
Simplify the logic of using rename() in xl. Currently, renaming
doesn't require the source object/dir to be existent in at least
read quorum disks, since there is no apparent reason for it
to be as a general rule, this commit will just simplify the
logic to avoid possible inconsistency in the backend in the future.
