It can happen with erroneous clients which do not send `Host:`
header until 4k worth of header bytes have been read. This can lead
to Peek() method of bufio to fail with ErrBufferFull.
To avoid this we should make sure that Peek buffer is as large as
our maxHeaderBytes count.
minio-java tests were failing under multiple places when
auto encryption was turned on, handle all the cases properly
This PR fixes
- CopyObject should decrypt ETag before it does if-match
- CopyObject should not try to preserve metadata of source
when rotating keys, unless explicitly asked by the user.
- We should not try to decrypt Compressed object etag, the
potential case was if user sets encryption headers along
with compression enabled.
Especially in gateway IAM admin APIs are not enabled
if etcd is not enabled, we should enable admin API though
but only enable IAM and Config APIs with etcd configured.
By default when we listen on all interfaces, we print all the
endpoints that at local to all interfaces including IPv6
addresses. Remove IPv6 addresses in endpoint list to be
printed in endpoints unless explicitly specified with '--address'
This commit adds an auto-encryption feature which allows
the Minio operator to ensure that uploaded objects are
always encrypted.
This change adds the `autoEncryption` configuration option
as part of the KMS conifguration and the ENV. variable
`MINIO_SSE_AUTO_ENCRYPTION:{on,off}`.
It also updates the KMS documentation according to the
changes.
Fixes#6502
Currently we use GetObject to check if we are allowed to list,
this might be a security problem since there are many users now
who actively disable a publicly readable listing, anyone who
can guess the browser URL can list the objects.
This PR turns off this behavior and provides a more expected way
based on the policies.
This PR also additionally improves the Download() object
implementation to use a more streamlined code.
These are precursor changes to facilitate federation and web
identity support in browser.
One user reported having discovered the following error:
API: SYSTEM()
Time: 20:06:17 UTC 12/06/2018
Error: xml: encoding "US-ASCII" declared but Decoder.CharsetReader is nil
1: cmd/handler-utils.go:43:cmd.parseLocationConstraint()
2: cmd/auth-handler.go:250:cmd.checkRequestAuthType()
3: cmd/bucket-handlers.go:411:cmd.objectAPIHandlers.PutBucketHandler()
4: cmd/api-router.go100cmd.(objectAPIHandlers).PutBucketHandler-fm()
5: net/http/server.go:1947:http.HandlerFunc.ServeHTTP()
Hence, adding support of different xml encoding. Although there
is no clear specification about it, even setting "GARBAGE" as an xml
encoding won't change the behavior of AWS, hence the encoding seems
to be ignored.
This commit will follow that behavior and will ignore encoding field
and consider all xml as utf8 encoded.
This refactors the vault configuration by moving the
vault-related environment variables to `environment.go`
(Other ENV should follow in the future to have a central
place for adding / handling ENV instead of magic constants
and handling across different files)
Further this commit adds master-key SSE-S3 support.
The operator can specify a SSE-S3 master key using
`MINIO_SSE_MASTER_KEY` which will be used as master key
to derive and encrypt per-object keys for SSE-S3
requests.
This commit is also a pre-condition for SSE-S3
auto-encyption support.
Fixes#6329
This PR implements one of the pending items in issue #6286
in S3 API a user can request CSV output for a JSON document
and a JSON output for a CSV document. This PR refactors
the code a little bit to bring this feature.
guessIsRPCReq() considers all POST requests as RPC but doesn't
check if this is an object operation API or not, which is actually
confusing bucket forwarder handler when it receives a new multipart
upload API which is a POST http request.
Due to this bug, users having a federated setup are not able to
upload a multipart object using an endpoint which doesn't actually
contain the specified bucket that will store the object.
Hence this commit will fix the described issue.
registering notFound handler more than once causes
gorilla mux to return error for all registered paths
greater than > 8. This might be a bug in the gorilla/mux
but we shouldn't be using it this way. NotFound handler
should be only registered once per root router.
Fixes#6915
When MINIO_PUBLIC_IPS is not specified and no endpoints are passed
as arguments, fallback to the address of non loop-back interfaces.
This is useful so users can avoid setting MINIO_PUBLIC_IPS in docker
or orchestration scripts, ince users naturally setup an internal
network that connects all instances.
This commit renames the env variable for vault namespaces
such that it begins with `MINIO_SSE_`. This is the prefix
for all Minio SSE related env. variables (like KMS).
clientID must be a unique `UUID` for each connections. Now, the
server generates it, rather considering the config.
Removing it as it is non-beneficial right now.
Fixes#6364
When migrating configs it happens often that some
servers fail to start due to version mismatch etc.
Hold a transaction lock such that all servers get
serialized.
This can create inconsistencies i.e Parts might have
lesser number of parts than ChecksumInfos. This will
result in object to be not readable.
This PR also allows for deleting previously created
corrupted objects.
globalMinioPort is used in federation which stores the address
and the port number of the server hosting the specified bucket,
this latter uses globalMinioPort but this latter is not set in
startup of the gateway mode.
This commit fixes the behavior.
Calling /minio/prometheuses/metrics calls xlSets.StorageInfo() which creates a new
storage REST client and closes it. However, currently, closing does nothing
to the underlying opened http client.
This commit introduces a closing behavior by calling CloseIdleConnections
provided by http.Transport upon the initialization of this latter.
This refactor brings a change which allows
targets to be added in a cleaner way and also
audit is now moved out.
This PR also simplifies logger dependency for auditing
The current code triggers a timeout to cleanup a heal seq from
healSeqMap, but we don't know if the user did or not launch a new
healing sequence with the same path.
Add endTime to healSequence struct and add a periodic heal-sequence
cleaner to remove heal sequences only if this latter is older than
10 minutes.
Rolling update doesn't work properly because Storage REST API has
a new API WriteAll() but without API version number increase.
Also be sure to return 404 for unknown http paths.
To conform with AWS S3 Spec on ETag for SSE-S3 encrypted objects,
encrypt client sent MD5Sum and store it on backend as ETag.Extend
this behavior to SSE-C encrypted objects.
This improves the performance of certain queries dramatically,
such as 'count(*)' etc.

xl.json is the source of truth for all erasure
coded objects, without which we won't be able to
read the objects properly. This PR enables sync
mode for writing `xl.json` such all writes go hit
the disk and are persistent under situations such
as abrupt power failures on servers running Minio.
This change will allow users to enter the endpoint of the
storage account if this latter belongs to a different Azure
cloud environment, such as US gov cloud.
e.g:
`MINIO_ACCESS_KEY=testaccount \
MINIO_SECRET_KEY=accountsecretkey \
minio gateway azure https://testaccount.blob.usgovcloudapi.net`
In many situations, while testing we encounter
ErrInternalError, to reduce logging we have
removed logging from quite a few places which
is acceptable but when ErrInternalError occurs
we should have a facility to log the corresponding
error, this helps to debug Minio server.
Multipart object final size is not a contiguous
encrypted object representation, so trying to
decrypt this size will lead to an error in some
cases. The multipart object should be detected first
and then decoded with its respective parts instead.
This PR handles this situation properly, added a
test as well to detect these in the future.
This commit adds key-rotation for SSE-S3 objects.
To execute a key-rotation a SSE-S3 client must
- specify the `X-Amz-Server-Side-Encryption: AES256` header
for the destination
- The source == destination for the COPY operation.
Fixes#6754
This PR adds support
- Request query params
- Request headers
- Response headers
AuditLogEntry is exported and versioned as well
starting with this PR.
On Windows erasure coding setup if
```
~ minio server V:\ W:\ X:\ Z:\
```
is not possible due to NTFS creating couple of
hidden folders, this PR allows minio to use
the entire drive.
Execute method in s3Select package makes a response.WriteHeader call.
Not calling it again in SelectObjectContentHandler function in case of
error in s3Select.Execute call.
On a heavily loaded server, getBucketInfo() becomes slow,
one can easily observe deleting an object causes many
additional network calls.
This PR is to let the underlying call return the actual
error and write it back to the client.
This PR supports two models for etcd certs
- Client-to-server transport security with HTTPS
- Client-to-server authentication with HTTPS client certificates
