This PR is an attempt to make this configurable

There is also a possibility that nodes have drifted

The earlier approach of using a license token for
communicating with SUBNET is being replaced
with a simpler mechanism of API keys. Unlike the
license which is a JWT token, these API keys will
be simple UUID tokens and don't have any embedded
information in them. SUBNET would generate the
API key on cluster registration, and then it would
be saved in this config, to be used for subsequent
communication with SUBNET.
- New sub-system has "region" and "name" fields.
- `region` subsystem is marked as deprecated, however still works, unless the
new region parameter under `site` is set - in this case, the region subsystem is
ignored. `region` subsystem is hidden from top-level help (i.e. from `mc admin
config set myminio`), but appears when specifically requested (i.e. with `mc
admin config set myminio region`).
- MINIO_REGION, MINIO_REGION_NAME are supported as legacy environment variables for server region.
- Adds MINIO_SITE_REGION as the current environment variable to configure the
server region and MINIO_SITE_NAME for the site name.
This feature is useful in situations when console is exposed

additionally optimize for IP only setups, avoid doing
unnecessary lookups if the Dial addr is an IP.
allow support for multiple listeners on same socket,
this is mainly meant for future purposes.
Before, the gateway will complain that it found KMS configured in the
environment but the gateway mode does not support encryption. This
commit will allow starting of the gateway but ensure that S3 operations
with encryption headers will fail when the gateway doesn't support
encryption. That way, the user can use etcd + KMS and have IAM data
encrypted in the etcd store.

improvements include
- skip IPv6 correctly
- do not set default value for
MINIO_SERVER_URL, let it be
configured if not use local IPs
Bonus:
- In healing return error from listPathRaw()
- update console to v0.8.3
its possible that some multipart uploads would have
uploaded only single parts so relying on `len(o.Parts)`
alone is not sufficient, we need to look for ETag

when TLS is configured using IPs directly
might interfere and not work properly when
the server is configured with TLS certs but
the certs only have domain certs.
Also additionally allow users to specify
a public accessible URL for console to talk
to MinIO i.e `MINIO_SERVER_URL` this would
allow them to use an external ingress domain
to talk to MinIO. This internally fixes few
problems such as presigned URL generation on
the console UI etc.
This needs to be done additionally for any
MinIO deployments that might have a much more
stricter requirement when running in standalone
mode such as FS or standalone erasure code.
MinIO might be running inside proxies, and
console while being on another port might not be
reachable on a specific port behind such proxies.
For such scenarios customize the redirect URL
such that console can be redirected to correct
proxy endpoint instead.

Bonus: remove kms_kes as sub-system, since its ENV only.
- also fixes a crash with etcd cluster without KMS
configured and also if KMS decryption is missing.
This feature also changes the default port where
the browser is running, now the port has moved
to 9001 and it can be configured with
```
--console-address ":9001"
```
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
In lieu of new changes coming for server command line, this
change is to deprecate strict requirement for distributed setups
to provide root credentials.
Bonus: remove MINIO_WORM warning from April 2020, it is time to
remove this warning.
This commit adds a check to the MinIO server setup that verifies
that MinIO can reach KES, if configured, and that the default key
exists. If the default key does not exist it will create it
automatically.

This commit replaces the custom KES client implementation
with the KES SDK from https://github.com/minio/kes
The SDK supports multi-server client load-balancing and
requests retry out of the box. Therefore, this change reduces
the overall complexity within the MinIO server and there
is no need to maintain two separate client implementations.

This commit reverts a change that added support for
parsing base64-encoded keys set via `MINIO_KMS_MASTER_KEY`.
The env. variable `MINIO_KMS_MASTER_KEY` is deprecated and
should ONLY support parsing existing keys - not the new format.
Any new deployment should use `MINIO_KMS_SECRET_KEY`. The legacy
env. variable `MINIO_KMS_MASTER_KEY` will be removed at some point
in time.

With this change, MinIO's ILM supports transitioning objects to a remote tier.
This change includes support for Azure Blob Storage, AWS S3 compatible object
storage incl. MinIO and Google Cloud Storage as remote tier storage backends.
Some new additions include:
- Admin APIs remote tier configuration management
- Simple journal to track remote objects to be 'collected'
This is used by object API handlers which 'mutate' object versions by
overwriting/replacing content (Put/CopyObject) or removing the version
itself (e.g DeleteObjectVersion).
- Rework of previous ILM transition to fit the new model
In the new model, a storage class (a.k.a remote tier) is defined by the
'remote' object storage type (one of s3, azure, GCS), bucket name and a
prefix.
* Fixed bugs, review comments, and more unit-tests
- Leverage inline small object feature
- Migrate legacy objects to the latest object format before transitioning
- Fix restore to particular version if specified
- Extend SharedDataDirCount to handle transitioned and restored objects
- Restore-object should accept version-id for version-suspended bucket (#12091)
- Check if remote tier creds have sufficient permissions
- Bonus minor fixes to existing error messages

This commit changes the config/IAM encryption
process. Instead of encrypting config data
(users, policies etc.) with the root credentials
MinIO now encrypts this data with a KMS - if configured.
Therefore, this PR moves the MinIO-KMS configuration (via
env. variables) to a "top-level" configuration.
The KMS configuration cannot be stored in the config file
since it is used to decrypt the config file in the first
place.
As a consequence, this commit also removes support for
Hashicorp Vault - which has been deprecated anyway.

This commit refactors the certificate management implementation
in the `certs` package such that multiple certificates can be
specified at the same time. Therefore, the following layout of
the `certs/` directory is expected:
```
certs/
│
├─ public.crt
├─ private.key
├─ CAs/ // CAs directory is ignored
│ │
│ ...
│
├─ example.com/
│ │
│ ├─ public.crt
│ └─ private.key
└─ foobar.org/
│
├─ public.crt
└─ private.key
...
```
However, directory names like `example.com` are just for human
readability/organization and don't have any meaning w.r.t whether
a particular certificate is served or not. This decision is made based
on the SNI sent by the client and the SAN of the certificate.
***
The `Manager` will pick a certificate based on the client trying
to establish a TLS connection. In particular, it looks at the client
hello (i.e. SNI) to determine which host the client tries to access.
If the manager can find a certificate that matches the SNI it
returns this certificate to the client.
However, the client may choose to not send an SNI or tries to access
a server directly via IP (`https://<ip>:<port>`). In this case, we
cannot use the SNI to determine which certificate to serve. However,
we also should not pick "the first" certificate that would be accepted
by the client (based on crypto. parameters - like a signature algorithm)
because it may be an internal certificate that contains internal hostnames.
We would disclose internal infrastructure details doing so.
Therefore, the `Manager` returns the "default" certificate when the
client does not specify an SNI. The default certificate the top-level
`public.crt` - i.e. `certs/public.crt`.
This approach has some consequences:
- It's the operator's responsibility to ensure that the top-level
`public.crt` does not disclose any information (i.e. hostnames)
that are not publicly visible. However, this was the case in the
past already.
- Any other `public.crt` - except for the top-level one - must not
contain any IP SAN. The reason for this restriction is that the
Manager cannot match a SNI to an IP b/c the SNI is the server host
name. The entire purpose of SNI is to indicate which host the client
tries to connect to when multiple hosts run on the same IP. So, a
client will not set the SNI to an IP.
If we would allow IP SANs in a lower-level `public.crt` a user would
expect that it is possible to connect to MinIO directly via IP address
and that the MinIO server would pick "the right" certificate. However,
the MinIO server cannot determine which certificate to serve, and
therefore always picks the "default" one. This may lead to all sorts
of confusing errors like:
"It works if I use `https:instance.minio.local` but not when I use
`https://10.0.2.1`.
These consequences/limitations should be pointed out / explained in our
docs in an appropriate way. However, the support for multiple
certificates should not have any impact on how deployment with a single
certificate function today.

object locking and retention implementation global
WORM is sort of deprecated, this has been mentioned

has come for this to go.
if needed use --no-compat to disable md5sum while
verifying any performance numbers.
bring back --compat behavior as default to avoid
additional documentation and confusing behavior,
as we are working towards improving md5sum to
be faster on AVX instructions, enabling this
should be hardly a problem in future versions
of MinIO.

The logging subsystem was initialized under init() method in
both gateway-main.go and server-main.go which are part of
same package. This created two logging targets and hence
errors were logged twice. This PR moves the init() method
to common-main.go
Changes in IP underneath are dynamic in replica sets
with multiple tenants, so deploying in that fashion
will not work until we wait for atleast one participatory
server to be local.
This PR also ensures that multi-tenant zone expansion also
works in replica set k8s deployments.
Introduces a new ENV `KUBERNETES_REPLICA_SET` check to call
appropriate code paths.
The approach is that now safe mode is only invoked when
we cannot read the config or under some catastrophic
situations, but not under situations when config entries
are invalid or unreachable. This allows for maximum
availability for MinIO and not fail on our users unlike
most of our historical releases.
- Migrate and save only settings which are enabled
- Rename logger_http to logger_webhook and
logger_http_audit to audit_webhook
- No more pretty printing comments, comment
is a key=value pair now.
- Avoid quotes on values which do not have space in them
- `state="on"` is implicit for all SetConfigKV unless
specified explicitly as `state="off"`
- Disabled IAM users should be disabled always
- Supports migrating only when the credential ENVs are set,
so any FS mode deployments which do not have ENVs set will
continue to remain as is.
- Credential ENVs can be rotated using MINIO_ACCESS_KEY_OLD
and MINIO_SECRET_KEY_OLD envs, in such scenarios it allowed
to rotate the encrypted content to a new admin key.
- This PR allows config KVS to be validated properly
without being affected by ENV overrides, rejects
invalid values during set operation
- Expands unit tests and refactors the error handling
for notification targets, returns error instead of
ignoring targets for invalid KVS
- Does all the prep-work for implementing safe-mode
style operation for MinIO server, introduces a new
global variable to toggle safe mode based operations
NOTE: this PR itself doesn't provide safe mode operations
