This commit adds a unit test for the vault
config verification (which covers also `IsEmpty()`).
Vault-related code is hard to test with unit tests
since a Vault service would be necessary. Therefore
this commit only adds tests for a fraction of the code.
Fixes#7409
Most hadoop distributions hortonworks, cloudera all
depend on aws-sdk-java 1.7.x to 1.10.x - the releases
which have bugs related case sensitive check for
ETag header. Go changes the case of the headers set
to be canonical but only preserves them when set
through a direct map.
This fixes most compatibility issues we have had
in the past supporting older hadoop distributions.
This commit fixes a privilege escalation issue against
the S3 and web handlers. An authenticated IAM user
can:
- Read from or write to the internal '.minio.sys'
bucket by simply sending a properly signed
S3 GET or PUT request. Further, the user can
- Read from or write to the internal '.minio.sys'
bucket using the 'Upload'/'Download'/'DownloadZIP'
API by sending a "browser" request authenticated
with its JWT token.
This commit fixes another privilege escalation issue
abusing the inter-node communication of distributed
servers to obtain/modify the server configuration.
The inter-node communication is authenticated using
JWT-Tokens. Further, IAM users accessing the cluster
via the web UI also get a JWT token and the browser
will add this "user" JWT token to each the request.
Now, a user can extract that JWT token an can craft
HTTP POST requests for the inter-node communication
API endpoint. Since the server accepts ANY valid
JWT token it also accepts inter-node commands from
an authenticated user such that the user can execute
arbitrary commands bypassing the IAM policy engine
and impersonate other users, change its own IAM policy
or extract the admin access/secret key.
This is fixed by only accepting "admin" JWT tokens
(tokens containing the admin access key - and therefore
were generated with the admin secret key). Consequently,
only the admin user can execute such inter-node commands.
Simplify the cmd/http package overall by removing
custom plain text v/s tls connection detection, by
migrating to go1.12 and choose minimum version
to be go1.12
Also remove all the vendored deps, since they
are not useful anymore.
A race is detected between a bytes.Buffer generated with cmd/rpc.Pool
and http2 module. An issue is raised in golang (https://github.com/golang/go/issues/31192).
Meanwhile, this commit disables Pool in RPC code and it generates a
new 1kb of bytes.Buffer for each RPC call.
Before this commit, nodes wait indefinitely without showing any
indicate error message when a node is started with different access
and secret keys.
This PR will show '401 Unauthorized' in this case.
Currently message is set to error type value.
Message field is not used in error logs. it is used only in the case of info logs.
This PR sets error message field to store error type correctly.
Copying an encrypted SSEC object when this latter is uploaded using
multipart mechanism was failing because ETag in case of encrypted
multipart upload is not encrypted.
This PR fixes the behavior.
This fixes varying pids for server-respawns. And avoids duplicate process
creating multiple pids when the server restart signal is triggered with
service restart enabled.
Fixes#7350
It is required to set the environment variable in the case of distributed
minio. LoadCredentials is used to notify peers of the change and will not work if
environment variable is set. so, this function will never be called.
In scenario 1
```
- bucket/object-prefix
- bucket/object-prefix/object
```
Server responds with `XMinioParentIsObject`
In scenario 2
```
- bucket/object-prefix/object
- bucket/object-prefix
```
Server responds with `XMinioObjectExistsAsDirectory`
Fixes#6566
