Harshavardhana 8e0910ab3e Fix build issues on BSDs in pkg/cpu (#7116)
Also add a cross compile script to test always cross
compilation for some well known platforms and architectures
, we support out of box compilation of these platforms even
if we don't make an official release build.

This script is to avoid regressions in this area when we
add platform dependent code.

Harshavardhana 6dd13e68c2 Support V2 signatures when autoencryption is enabled (#7084)
When auto-encryption is turned on, we pro-actively add SSEHeader
for all PUT, POST operations. This is unusual for V2 signature
calculation because V2 signature doesn't have a pre-defined set
of signed headers in the request like V4 signature. According to
V2 we should canonicalize all incoming supported HTTP headers.

Make sure to validate signatures before we mutate http headers

Nick Craig-Wood 9c26fe47b0 Fix server side copy of files with `?` in - fixes #7058 (#7059)
Before this change the CopyObjectHandler and the CopyObjectPartHandler
both looked for a `versionId` parameter on the `X-Amz-Copy-Source` URL
for the version of the object to be copied on the URL unescaped version
of the header.  This meant that files that had question marks in were
truncated after the question mark so that files with `?` in their
names could not be server side copied.

After this change the URL unescaping is done during the parsing of the
`versionId` parameter which fixes the problem.

This change also introduces the same logic for the
`X-Amz-Copy-Source-Version-Id` header field which was previously
ignored, namely returning an error if it is present and not `null`
since minio does not currently support versions.

poornas 5a80cbec2a Add double encryption at S3 gateway. (#6423)
This PR adds pass-through, single encryption at gateway and double
encryption support (gateway encryption with pass through of SSE
headers to backend).

If KMS is set up (either with Vault as KMS or using
MINIO_SSE_MASTER_KEY),gateway will automatically perform
single encryption. If MINIO_GATEWAY_SSE is set up in addition to
Vault KMS, double encryption is performed.When neither KMS nor
MINIO_GATEWAY_SSE is set, do a pass through to backend.

When double encryption is specified, MINIO_GATEWAY_SSE can be set to
"C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3
encryption at gateway/backend or both to support more than one option.

minio-java tests were failing under multiple places when

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.

Harshavardhana 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.

Anis Elleuch 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.

Andreas Auernhammer 21d8c0fd13 refactor vault configuration and add master-key KMS (#6488)
This refactors the vault configuration by moving the

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.

Anis Elleuch 40852801ea fix: Better check of RPC type requests (#6927)
guessIsRPCReq() considers all POST requests as RPC but doesn't

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.

Anis Elleuch 69bd6df464 storage: Implement Close() in REST client (#6826)
Calling /minio/prometheuses/metrics calls xlSets.StorageInfo() which creates a new
storage REST client and closes it. However, currently, closing does nothing
to the underlying opened http client.

This commit introduces a closing behavior by calling CloseIdleConnections
provided by http.Transport upon the initialization of this latter.

Anis Elleuch 7b579caf68 heal: Fix heal sequences cleanup process (#6780)
The current code triggers a timeout to cleanup a heal seq from
healSeqMap, but we don't know if the user did or not launch a new
healing sequence with the same path.

Add endTime to healSequence struct and add a periodic heal-sequence
cleaner to remove heal sequences only if this latter is older than
10 minutes.
