This refactor brings a change which allows
targets to be added in a cleaner way and also
audit is now moved out.
This PR also simplifies logger dependency for auditing
To conform with AWS S3 Spec on ETag for SSE-S3 encrypted objects,
encrypt client sent MD5Sum and store it on backend as ETag.Extend
this behavior to SSE-C encrypted objects.
This improves the performance of certain queries dramatically,
such as 'count(*)' etc.
Without this PR
```

With this PR
```
~ time mc select --query "select count(*) from S3Object" myminio/sjm-airlines/star2000.csv.gz
2173762
real 0m17.603s
user 0m0.093s

```
Almost a 250% improvement in performance. This PR avoids a lot of type
conversions and instead relies on raw sequences of data and interprets
them lazily.

In many situations, while testing we encounter
ErrInternalError, to reduce logging we have
removed logging from quite a few places which
is acceptable but when ErrInternalError occurs
we should have a facility to log the corresponding
error, this helps to debug Minio server.
This commit adds key-rotation for SSE-S3 objects.
To execute a key-rotation a SSE-S3 client must
- specify the `X-Amz-Server-Side-Encryption: AES256` header
for the destination
- The source == destination for the COPY operation.
Fixes#6754
This PR adds support
- Request query params
- Request headers
- Response headers
AuditLogEntry is exported and versioned as well
starting with this PR.
Execute method in s3Select package makes a response.WriteHeader call.
Not calling it again in SelectObjectContentHandler function in case of
error in s3Select.Execute call.
On a heavily loaded server, getBucketInfo() becomes slow,
one can easily observe deleting an object causes many
additional network calls.
This PR is to let the underlying call return the actual
error and write it back to the client.
Current master didn't support CopyObjectPart when source
was encrypted, this PR fixes this by allowing range
CopySource decryption at different sequence numbers.
Fixes#6698
This PR fixes
- The target object should be compressed even if the
source object is not compressed.
- The actual size for an encrypted object should be the
`decryptedSize`
This commit fixes a wrong assignment to `actualPartSize`.
The `actualPartSize` for an encrypted src object is not `srcInfo.Size`
because that's the encrypted object size which is larger than the
actual object size. So the actual part size for an encrypted
object is the decrypted size of `srcInfo.Size`.
Without this fix we have room for two different type of
errors.
- Source is encrypted and we didn't provide any source encryption keys
This results in Incomplete body error to be returned back to the client
since source is encrypted and we gave the reader as is to the object
layer which was of a decrypted value leading to "IncompleteBody"
- Source is not encrypted and we provided source encryption keys.
This results in a corrupted object on the destination which is
considered encrypted but cannot be read by the server and returns
the following error.
```
<Error><Code>XMinioObjectTampered</Code><Message>The requested object
was modified and may be compromised</Message><Resource>/id-platform-gamma/
</Resource><RequestId>155EDC3E86BFD4DA</RequestId><HostId>3L137</HostId>
</Error>
```
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
The new call combines GetObjectInfo and GetObject, and returns an
object with a ReadCloser interface.
Also adds a number of end-to-end encryption tests at the handler
level.
* Revert "Encrypted reader wrapped in NewGetObjectReader should be closed (#6383)"
This reverts commit 53a0bbeb5b.
* Revert "Change SelectAPI to use new GetObjectNInfo API (#6373)"
This reverts commit 5b05df215a.
* Revert "Implement GetObjectNInfo object layer call (#6290)"
This reverts commit e6d740ce09.
This combines calling GetObjectInfo and GetObject while returning a
io.ReadCloser for the object's body. This allows the two operations to
be under a single lock, fixing a race between getting object info and
reading the object body.
This commit adds error handling for SSE-KMS requests to
HEAD, GET, PUT and COPY operations. The server responds
with `not implemented` if a client sends a SSE-KMS
request.
