Fixes#1428
The `x-amz-expected-bucket-owner` header in S3 specifies the account ID of the expected bucket owner. If the account ID provided does not match the actual owner of the bucket, the request fails with an HTTP 403 Forbidden (AccessDenied) error. If the provided account ID is not 12 characters long, S3 returns a 400 Bad Request error.
In our case, we expect the header to contain the bucket owner’s access key ID, and we skip validation errors related to the access key ID, since there is no validation mechanism for user access key IDs. If the provided value does not match the bucket owner’s access key ID, the gateway returns an AccessDenied error.
A few integration tests are added for random actions, as this feature applies to all actions, but it is unnecessary to add test cases for every single one.
Adjusts the admin apis to the new advanced routing changes.
Enables debug logging for the separate admin server(when a separate server is run for the admin apis).
Adds the quiet mode for the separate admin server.
Fixes#1036
Fixes the issue when calling a non-existing root endpoint(POST /) the gateway returns `NoSuchBucket`. Now it returns the correct `MethodNotAllowed` error.
This implementation introduces **public buckets**, which are accessible without signature-based authentication.
There are two ways to grant public access to a bucket:
* **Bucket ACLs**
* **Bucket Policies**
Only `Get` and `List` operations are permitted on public buckets. All **write operations** require authentication, regardless of whether public access is granted through an ACL or a policy.
The implementation includes an `AuthorizePublicBucketAccess` middleware, which checks if public access has been granted to the bucket. If so, authentication middlewares are skipped. For unauthenticated requests, appropriate errors are returned based on the specific S3 action.

**1. Bucket-Level Operations:**
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": "*",
"Action": "s3:*",
"Resource": "arn:aws:s3:::test"
}
]
}
```
**2. Object-Level Operations:**
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": "*",
"Action": "s3:*",
"Resource": "arn:aws:s3:::test/*"
}
]
}
```
**3. Both Bucket and Object-Level Operations:**
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": "*",
"Action": "s3:*",
"Resource": "arn:aws:s3:::test"
},
{
"Effect": "Allow",
"Principal": "*",
"Action": "s3:*",
"Resource": "arn:aws:s3:::test/*"
}
]
}
```

```sh
aws s3api create-bucket --bucket test --object-ownership BucketOwnerPreferred
aws s3api put-bucket-acl --bucket test --acl public-read
```
Implements the bucket cors s3 actions in FE to return `NotImplemented` error.
Actions implemented:
- `PutBucketCors`
- `GetBucketCors`
- `DeleteBucketCors`
`Note`: no logic is implemented for the actions in any backend and no input or output data validation is added.
We were trying to parse a non existing acl and returning an
internal server error due to invalid json acl data.
If the bucket acl does not exist, return a default acl with the
root account as the owner.
This fixes#1060, but does not address the invalid acl format
from s3cmd reported in #963.
Bucket ACLs are now disabled by default the same as AWS.
By default the object ownership is BucketOwnerEnforced
which means that bucket ACLs are disabled. If one attempts
to set bucket ACL the following error is returned both in
the gateway and on AWS:
ErrAclNotSupported: {
Code: "AccessControlListNotSupported",
Description: "The bucket does not allow ACLs",
HTTPStatusCode: http.StatusBadRequest,
},
ACls can be enabled with PutBucketOwnershipControls
Changed bucket canned ACL translation
New backend interface methods:
PutBucketOwnershipControls
GetBucketOwnershipControls
DeleteBucketOwnershipControls
Added these to metrics
This moves the internal iam service from the posix backend so
that we can start implementing new iam services right in the auth
module.
The internal iam service has same behavior as before, but now
must be enabled with the --iam-dir cli option.
New single user service is the default when no other iam service
is selected. This just runs the gateway in single user mode with
just the root account.
This adds a context to the backend interface calls so that the backend
can enable request cancellation. This change isn't acutally implementing
any backend handling, but just putting the pieces into place to pass the
context to the backend.
