a536cf5dc0 Buffconn should buffer upto maxHeaderBytes to avoid ErrBufferFull (#7017)
It can happen with erroneous clients which do not send `Host:`
header until 4k worth of header bytes have been read. This can lead
to Peek() method of bufio to fail with ErrBufferFull.

To avoid this we should make sure that Peek buffer is as large as
our maxHeaderBytes count.

d2f8f8c7ee Fix ETag handling with auto-encryption with CopyObject conditions (#7000)
minio-java tests were failing under multiple places when
auto encryption was turned on, handle all the cases properly

This PR fixes

 - CopyObject should decrypt ETag before it does if-match
 - CopyObject should not try to preserve metadata of source
   when rotating keys, unless explicitly asked by the user.
 - We should not try to decrypt Compressed object etag, the
   potential case was if user sets encryption headers along
   with compression enabled.

d264d2c899 add auto-encryption feature (#6523)
This commit adds an auto-encryption feature which allows
the Minio operator to ensure that uploaded objects are
always encrypted.

This change adds the `autoEncryption` configuration option

`MINIO_SSE_AUTO_ENCRYPTION:{on,off}`.

It also updates the KMS documentation according to the
changes.

c2ed1347d9 Do not list objects unless specified in policy (#6970)
Currently we use GetObject to check if we are allowed to list,
this might be a security problem since there are many users now
who actively disable a publicly readable listing, anyone who
can guess the browser URL can list the objects.

This PR turns off this behavior and provides a more expected way
based on the policies.

This PR also additionally improves the Download() object
implementation to use a more streamlined code.

These are precursor changes to facilitate federation and web
identity support in browser.

50f6f9fe58 S3 api: Ignore encoding in xml body (#6953)
One user reported having discovered the following error:

API: SYSTEM()
Time: 20:06:17 UTC 12/06/2018
Error: xml: encoding "US-ASCII" declared but Decoder.CharsetReader is nil
1: cmd/handler-utils.go:43:cmd.parseLocationConstraint()
2: cmd/auth-handler.go:250:cmd.checkRequestAuthType()
3: cmd/bucket-handlers.go:411:cmd.objectAPIHandlers.PutBucketHandler()
4: cmd/api-router.go100cmd.(objectAPIHandlers).PutBucketHandler-fm()
5: net/http/server.go:1947:http.HandlerFunc.ServeHTTP()

Hence, adding support of different xml encoding. Although there
is no clear specification about it, even setting "GARBAGE" as an xml
encoding won't change the behavior of AWS, hence the encoding seems
to be ignored.

This commit will follow that behavior and will ignore encoding field
and consider all xml as utf8 encoded.

21d8c0fd13 refactor vault configuration and add master-key KMS (#6488)
This refactors the vault configuration by moving the
vault-related environment variables to `environment.go`
(Other ENV should follow in the future to have a central
place for adding / handling ENV instead of magic constants
and handling across different files)

Further this commit adds master-key SSE-S3 support.
The operator can specify a SSE-S3 master key using
`MINIO_SSE_MASTER_KEY` which will be used as master key
to derive and encrypt per-object keys for SSE-S3
requests.

This commit is also a pre-condition for SSE-S3
auto-encyption support.

40852801ea fix: Better check of RPC type requests (#6927)
guessIsRPCReq() considers all POST requests as RPC but doesn't
check if this is an object operation API or not, which is actually
confusing bucket forwarder handler when it receives a new multipart
upload API which is a POST http request.

Due to this bug, users having a federated setup are not able to
upload a multipart object using an endpoint which doesn't actually
contain the specified bucket that will store the object.

Hence this commit will fix the described issue.

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.

fdf691fdcc move SSE-C TLS enforcement into generic handler (#6639)
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.

baec331e84 crypto: add functions for sealing/unsealing the etag for SSE (#6618)
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.

ea9408ccbb worm: when enabled, avoid renaming the existing object in tmp directory (#6560)
In XL PutObject & CompleteMultipartUpload, the existing object is renamed
to the temporary directory before checking if worm is enabled or not.

Most of the times, this doesn't cause an issue unless two uploads to the
same location occurs at the same time. Since there is no locking in object
handlers, both uploads will reach XL layer. The second client acquiring
write lock in put object or complete upload in XL will rename the object
to the temporary directory before doing the check and returning the error (wrong!).

This commit fixes then the behavior: no rename to temporary directory if
worm is enabled.

This PR uploads stream in blocks and finally commits the blocks
allowing for low memory footprint while uploading large objects
through Minio browser UI.

This PR also adds ETag compatibility for single PUT operations.

```
WARNING: DATA RACE

The reason for this data race is that some admin tests are not waiting for go routines
that they created to be properly exited, which triggers the race detector.

052a7b8eec Allow minio s3 gateway to use different AWS auth mechanisms (#6422)
Allow minio s3 gateway to use aws environment credentials,
IAM instance credentials, or AWS file credentials.

If AWS_ACCESS_KEY_ID, AWS_SECRET_ACCSES_KEY are set, 
or minio is running on an ec2 instance with IAM instance credentials, 
or there is a file $HOME/.aws/credentials, minio running as an S3
gateway will authenticate with AWS S3 using those one of credentials.

The lookup order:
1. AWS environment varaibles
2. IAM instance credentials
3. $HOME/.aws/credentials
4. minio environment variables

To authenticate with the minio gateway, you will always use the
minio environment variables MINIO_ACCESS_KEY MINIO_SECRET_KEY.

Two handlers are added to admin API to enable profiling and disable
profiling of a server in a standalone mode, or all nodes in the
distributed mode.

/minio/admin/profiling/start/{cpu,block,mem}:
  - Start profiling and return starting JSON results, e.g. one
    node is offline.

/minio/admin/profiling/download:
  - Stop the on-going profiling task
  - Stream a zip file which contains all profiling files that can

66fda7a37f Use retry mechanism when initializing configuration (#6475)
Currently, one node in a cluster can fail to boot with the following error message:

```
ERROR Unable to initialize config system: Storage resources are insufficient for the write operation
```

  This happens when disks are formatted, read quorum is met but write
quorum is not met. In checkServerConfig(), a insufficient read quorum
error is replaced by errConfigNotFound, the code will generate a
new config json and try to save it, but it will fail because write
quorum is not met.

  Replacing read quorum with errConfigNotFound is also wrong because it
can lead, in rare cases, to overwrite the config set by the user.

  So, this commit adds a retry mechanism in configuration initialization
to retry only with read or write quorum errors.

  This commit will also fix the following cases:
 - Read quorum is lost just after the initialization of the object layer.
 - Write quorum not met when upgrading configuration version.
