With the implementation of dummy GET ACL handlers,
tools like s3cmd perform few operations which causes
the ACL call to be invoked. Make sure that in our
router configuration GET?acl comes before actual
GET call to facilitate this dummy call.
tests were written in the manner by editing internal
variables of fsObjects to mimic certain behavior from
APIs, but this is racy when an active go-routine is
reading from the same variable.
Make sure to terminate the go-routine if possible for
these tests.
The current problem is that when you invoke
```
mc admin info myminio | head -1
● localhost:9000
```
This output is incorrect as the expected output should be
```
mc admin info myminio | head -1
● 192.168.1.17:9000
```
This commit adds a check to the server's admin-API such that it only
accepts Admin-API requests with authenticated bodies. Further this
commit updates the `madmin` package to always add the
`X-Amz-Content-Sha256` header.
This change improves the Admin-API security since the server does not
accept unauthenticated request bodies anymore.
After this commit `mc` must be updated to the new `madmin` api because
requests over TLS connections will fail.
This commit fixes a DoS vulnerability for certain APIs using
signature V4 by verifying the content-md5 and/or content-sha56 of
the request body in a streaming mode.
The issue was caused by reading the entire body of the request into
memory to verify the content-md5 or content-sha56 checksum if present.
The vulnerability could be exploited by either replaying a V4 request
(in the 15 min time frame) or sending a V4 presigned request with a
large body.
This PR fixes a regression where the remote bucket policies
were not updated due to policy.Resource not having exported
fields, gob fails with unexported fields while marshalling.
Removed field minio_http_requests_total as it was redundant with
minio_http_requests_duration_seconds_count
Also removed field minio_server_start_time_seconds as it was
redundant with process_start_time_seconds
Minio server supports healthcheck and prometheus related
unauthenticated endpoints. This document summarizes this
information in a single place and add links for more detailed
documentation if needed.
GetBucketACL call returns empty for all GET in ACL requests,
the primary purpose of this PR is to provide legacy API support
for legacy applications.
Fixes#5706
Better support of HEAD and listing of zero sized objects with trailing
slash (a.k.a empty directory). For that, isLeafDir function is added
to indicate if the specified object is an empty directory or not. Each
backend (xl, fs) has the responsibility to store that information.
Currently, in both of XL & FS, an empty directory is represented by
an empty directory in the backend.
isLeafDir() checks if the given path is an empty directory or not,
since dir listing is costly if the latter contains too many objects,
readDirN() is added in this PR to list only N number of entries.
In isLeadDir(), we will only list one entry to check if a directory
is empty or not.
