Klaus Post c9b8bd8de2 S3 Select: optimize output (#8238)
Queue output items and reuse them.
Remove the unneeded type system in sql and just use the Go type system.

In best case this is more than an order of magnitude speedup:

Harshavardhana b52a3e523c Avoid using fastjson parser pool, move back to jsoniter (#8190)
It looks like from implementation point of view fastjson
parser pool doesn't behave the same way as expected
when dealing many `xl.json` from multiple disks.

The fastjson parser pool usage ends up returning incorrect
xl.json entries for checksums, with references pointing
to older entries. This led to the subtle bug where checksum
info is duplicated from a previous xl.json read of a different
file from different disk.

Andreas Auernhammer 810a44e951 KMS Admin-API: add route and handler for KMS key info (#7955)
This commit adds an admin API route and handler for
requesting status information about a KMS key.

Therefore, the client specifies the KMS key ID (when
empty / not set the server takes the currently configured
default key-ID) and the server tries to perform a dummy encryption,
re-wrap and decryption operation. If all three succeed we know that
the server can access the KMS and has permissions to generate, re-wrap
and decrypt data keys (policy is set correctly).

maihde 5cd9f10a02 Support Federation on a single machine (#8009)
When checking if federation is necessary, the code compares
the SRV record stored in etcd against the list of endpoints
that the MinIO server is exposing.  If there is an intersection
in this list the request is forwarded.

The SRV record includes both the host and the port, but the
intersection check previously only looked at the IP address.  This
would prevent federation from working in situations where the endpoint
IP is the same for multiple MinIO servers.  Some examples of where this
can occur are:
 - running mulitiple copies of MinIO on the same host
 - using multiple MinIO servers behind a NAT with port-forwarding

Ryan Tam bd56f80250 Fix ignored alias for aggregate result in S3 Select (#7849)
The SQL parser as it stands right now ignores alias for aggregate
result, e.g. `SELECT COUNT(*) AS thing FROM s3object` doesn't actually
return record like `{"thing": 42}`, it returns a record like `{"_1": 42}`.
Column alias for aggregate result is supported in AWS's S3 Select, so
this commit fixes that by respecting the `expr.As` in the expression.

Also improve test for S3 select

On top of testing a simple `SELECT` query, we want to test a few more
"advanced" queries (e.g. aggregation).

Convert existing tests into table driven tests[1], and add the new test
cases with "advanced" queries into them.

Harshavardhana 99bf4d0c42 [sec] Match ${aws:username} exactly instead of prefix match (#7791)
This PR fixes a security issue where an IAM user based
on his policy is granted more privileges than restricted
by the users IAM policy.

This is due to an issue of prefix based Matcher() function
which was incorrectly matching prefix based on resource
prefixes instead of exact match.

Anis Elleuch 3099af70a3 Add admin get/set config keys API (#6113)
This PR adds two new admin APIs in Minio server and madmin package:
- GetConfigKeys(keys []string) ([]byte, error)
- SetConfigKeys(params map[string]string) (err error)

A key is a path in Minio configuration file, (e.g. notify.webhook.1)

The user will always send a string value when setting it in the config file,
the API will know how to convert the value to the appropriate type. The user
is also able to set a raw json.

Before setting a new config, Minio will validate all fields and try to connect
to notification targets if available.
