This commit fixes an AWS S3 incompatibility issue.
The AccessKeyID may contain one or more `/` which caused
the server to interpret parts of the AccessKeyID as
other `X-Amz-Credential` parameters (like date, region, ...)
This commit fixes this by allowing 5 or more
`X-Amz-Credential` parameter strings and only interpreting
the last 5.
Fixes#6443
This commit will print connection failures to other disks in other nodes
after 5 retries. It is useful for users to understand why the
distribued cluster fails to boot up.
Enhance a little bit the error message that is showing
when access & secret keys are not specified in the
environment when running Minio in gateway and server mode.
This commit also removes a redundant check of access/secret keys.
This commit fixes the Manta gateway client creation flow. We now affix
the endpoint scheme with endpoint URL while creating the Manta client
for gateway.
Also add steps in Manta gateway docs on how to run with custom Manta
endpoint.
Fixes#6408
This commit fixes are regression in the server regarding
handling SSE requests with wrong SSE-C keys.
The server now returns an AWS S3 compatable API error (access denied)
in case of the SSE key does not match the secret key used during upload.
Fixes#6431
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.
Currently Go http connection pool was not being properly
utilized leading to degrading performance as the number
of concurrent requests increased.
As recommended by Go implementation, we have to drain the
response body and close it.
Removing an empty directory is not working because of xl.DeleteObject()
was only checking if the passed prefix is an actual object but it
should also check if it is an empty directory.
soMaxConn value is 128 on almost all linux systems,
this value is too low for Minio at times when used
against large concurrent workload e.g: spark applications
this causes a sort of SYN flooding observed by the kernel
to allow for large backlog increase this value to 2048.
With this value we do not see anymore SYN flooding
kernel messages.
ListMultipartUploads implementation is meant for docker-registry
use-case only. It lists only the first upload with a prefix matching
the object being uploaded.

An issue was reproduced when minio-js client functional
tests are setting lower case http headers, in our current
master branch we specifically look for canonical host header
which may be not necessarily true for all http clients.
This leads to a perpetual hang on the *net.Conn*.
This PR fixes regression caused by #6206 by handling the
case insensitivity.
This combines calling GetObjectInfo and GetObject while returning a
io.ReadCloser for the object's body. This allows the two operations to
be under a single lock, fixing a race between getting object info and
reading the object body.
One typo introduced in a recent commit miscalculates if worm and browser
are enabled or not. A simple test is also added to detect this issue
in the future if it ever happens again.
In current master when you do `mc watch` you can see a
dynamic ARN being listed which exposes the remote IP as well
```
mc watch play/airlines

SQS ARNs listed as part of ServerInfo should be only external targets,
since listing an ARN here is not useful and it cannot be re-purposed in
any manner.
This PR fixes this issue by filtering out httpclient from the ARN list.
This is a regression introduced in #52940e4431725c
This commit adds error handling for SSE-KMS requests to
HEAD, GET, PUT and COPY operations. The server responds
with `not implemented` if a client sends a SSE-KMS
request.
This package provide customizable TCP net.Listener with various
performance-related options:
* SO_REUSEPORT. This option allows linear scaling server performance
on multi-CPU servers.
See https://www.nginx.com/blog/socket-sharding-nginx-release-1-9-1/ for details.
* TCP_DEFER_ACCEPT. This option expects the server reads from the accepted
connection before writing to them.
* TCP_FASTOPEN. See https://lwn.net/Articles/508865/ for details.
Add support for sse-s3 encryption with vault as KMS.
Also refactoring code to make use of headers and functions defined in
crypto package and clean up duplicated code.
This PR fixes a regression introduced in 8eb838bf91
where hashing technique was used on prefixes to get the right set
to perform the operation, this is not correct since prefixes and
their corresponding keys might hash to a different value depending
on the key length.
For prefixes/directories we should look everywhere to support proper
quorum based listing.
Fixes#6293
This PR is the first set of changes to move the config
to the backend, the changes use the existing `config.json`
allows it to be migrated such that we can save it in on
backend disks.
In future releases, we will slowly migrate out of the
current architecture.
Fixes#6182
Modified the LogIf function to log only if the error passed
is not on the ignored errors list.
Currently, only disk not found error is added to the list.
Added a new function in logger package called LogAlwaysIf,
which will print on any error.
Fixes#5997
This commit adds support for detecting SSE-KMS headers.
The server should be able to detect SSE-KMS headers to
at least fail such S3 requests with not implemented.
When a S3 client sends a GET Object with a range header, 206 http
code is returned indicating success, however the call of the object
layer's GetObject() inside the handler can return an error and will lead
to writing an XML error message, which is obviously wrong since
we already sent 206 http code. So in the case, we just stop sending
data to the S3 client, this latter can still detect if there is no
error when comparing received data with Content-Length header
in the Get Object response.
ANSI colors do not work on dumb terminals, in situations
when minio is running as a service under systemd.
This PR ensures we turn off color in those situations.
This is to avoid serializing RPC contention on ongoing
parallel operations, the blocking profile indicating
all calls were being serialized through setRetryTicker.
This commit adds the crypto.* errors to the
`toAPIErrorCode` switch. Further this commit adds an S3
API error code returned whenever the client specifes a
SSE-S3 request with an invalid algorithm parameter.
Fixes#6238
globalPolicySys used to be initialized in fs/xl layer. The referenced
commit moved this logic to server/gateway initialization,but a check
to avoid double initialization prevented globalPolicySys to be loaded
from disk for NAS.
fixes regression from commit be1700f595
No locks are ever left in memory, we also
have a periodic interval of clearing stale locks
anyways. The lock instrumentation was not complete
and was seldom used.
Deprecate this for now and bring it back later if
it is really needed. This also in-turn seems to improve
performance slightly.
POST mime/multipart upload style can have filename value optional
which leads to implementation issues in Go releases in their
standard mime/multipart library.
When `filename` doesn't exist Go doesn't update `form.File` which
we rely on to extract the incoming file data, strangely when `filename`
is not specified this data is buffered in memory and is now part of
`form.Value` instead of `form.File` which creates an inconsistent
behavior.
This PR tries to fix this in our code for the time being, but ideal PR
would be to fix the upstream mime/multipart library to handle the
above situation consistently.
This commit adds a `fmt.Stringer` implementation for
SSE-S3 and SSE-C. The string representation is the
domain used for object key sealing.
See: `ObjectKey.Seal(...)` and `ObjectKey.Unseal(...)`

Our posix.go implementation did not handle I/O errors
properly on the disks, this led to situations where
top-level callers such as ListObjects might return early
without even verifying all the available disks.
This commit tries to address this in Kubernetes, drbd/nbd based
persistent volumes which can disconnect under load and
result in the situations with disks return I/O errors.
This commit also simplifies listing operation, listing
never returns any error. We can avoid this since we pretty
much ignore most of the errors anyways. When objects are
accessed directly we return proper errors.
* crypto: add support for parsing SSE-C/SSE-S3 metadata
This commit adds support for detecting and parsing
SSE-C/SSE-S3 object metadata. With the `IsEncrypted`
functions it is possible to determine whether an object
seems to be encrypted. With the `ParseMetadata` functions
it is possible to validate such metadata and extract the
SSE-C/SSE-S3 related values.
It also fixes some naming issues.
* crypto: add functions for creating SSE object metadata
This commit adds functions for creating SSE-S3 and
SSE-C metadata. It also adds a `CreateMultipartMetadata`
for creating multipart metadata.
For all functions unit tests are included.
Since implementing `pwrite` like implementation would
require a more complex code than background append
implementation, it is better to keep the current code
as is and not implement `pwrite` based functionality.
Closes#4881
Healthcheck handler in current implementation was
performing ListBuckets() to check for liveness of Minio
service. ListBuckets() implementation on the other hand
doesn't do quorum based listing and if one of the disks
returned error, an I/O error it would be lead to kubernetes
taking the minio pod down prematurely even if the disk
is not local to that minio server.
The reason is ListBuckets() call cannot be trusted to
provide us the valid information that we need, Minio is a
clustered application which is designed to handle disk
failures. Error on one of the disks doesn't mean the pod
should become fully non-operational.
This PR attempts to fix this by only checking for alive
disks which are local to each setup and also by simply
performing a Stat() operation, if the Stat() returned
error on all disks local to a particular server then
we can let kubernetes safely take it down, until then
we should be operational.
The current code for deleting 1000 objects simultaneously
causes significant random I/O, which on slower drives
leads to servers disconnecting in a distributed setup.
Simplify this by serially deleting and reducing the
chattiness of this operation.
Currently, requestid field in logEntry is not populated, as the
requestid field gets set at the very end.
It is now set before regular handler functions. This is also
useful in setting it as part of the XML error response.
Travis build for ppc64le has been quite inconsistent and stays queued
for most of the time. Removing this build as part of Travis.yml for
the time being.
- Add console target logging, enabled by default.
- Add http target logging, which supports an endpoint
with basic authentication (username/password are passed
in the endpoint url itself)
- HTTP target logging is asynchronous and some logs can be
dropped if channel buffer (10000) is full
In a small window, UI error tries to split lines for an eye candy
error message. However, since we show some docs.minio.io links in some
error messages, these links are actually broken and not easily selected
in a X terminal. This PR changes the behavior and won't split lines
anymore.
