It looks like from implementation point of view fastjson
parser pool doesn't behave the same way as expected
when dealing many `xl.json` from multiple disks.
The fastjson parser pool usage ends up returning incorrect
xl.json entries for checksums, with references pointing
to older entries. This led to the subtle bug where checksum
info is duplicated from a previous xl.json read of a different
file from different disk.
This commit adds an admin API route and handler for
requesting status information about a KMS key.
Therefore, the client specifies the KMS key ID (when
empty / not set the server takes the currently configured
default key-ID) and the server tries to perform a dummy encryption,
re-wrap and decryption operation. If all three succeed we know that
the server can access the KMS and has permissions to generate, re-wrap
and decrypt data keys (policy is set correctly).
The change now is to ensure that we take custom URL as
well for updating the deployment, this is required for
hotfix deliveries for certain deployments - other than
the community release.
This commit changes the previous work d65a2c6725
with newer set of requirements.
Also deprecates PeerUptime()
Add API to set policy mapping for a user or group
Contains a breaking Admin APIs change.
- Also enforce all applicable policies
- Removes the previous /set-user-policy API
Bump up peerRESTVersion
Add get user info API to show groups of a user
This change adds admin APIs and IAM subsystem APIs to:
- add or remove members to a group (group addition and deletion is
implicit on add and remove)
- enable/disable a group
- list and fetch group info
This API returns the information related to the self healing routine.
For the moment, it returns:
- The total number of objects that are scanned
- The last time when an item was scanned
Healing scan used to read all objects parts to check for bitrot
checksum. This commit will add a quicker way of healing scan
by only checking if parts are actually present in disks or not.
foo.CORRUPTED should never be created because when
multiple sets are involved we would hash the file
to wrong a location, this PR removes the code.
But allows DeleteBucket() to work properly to delete
dangling buckets/objects. Also adds another option
to Healing where a user needs to specify `--remove`
such that all dangling objects will be deleted with
user confirmation.
Collect historic cpu and mem stats. Also, use actual values
instead of formatted strings while returning to the client. The string
formatting prevents values from being processed by the server or
by the client without parsing it.
This change will allow the values to be processed (eg.
compute rolling-average over the lifetime of the minio server)
and offloads the formatting to the client.
This is part of implementation for mc admin health command. The
ServerDrivesPerfInfo() admin API returns read and write speed
information for all the drives (local and remote) in a given Minio
server deployment.
Part of minio/mc#2606
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
User's key should satisfy the requirement of `mc config host add`.
Check access key and secret key length before adding a new user,
avoid creating a useless user which cannot be added into config
host or log into the browser.
This PR introduces two new features
- AWS STS compatible STS API named AssumeRoleWithClientGrants
```
POST /?Action=AssumeRoleWithClientGrants&Token=<jwt>
```
This API endpoint returns temporary access credentials, access
tokens signature types supported by this API
- RSA keys
- ECDSA keys
Fetches the required public key from the JWKS endpoints, provides
them as rsa or ecdsa public keys.
- External policy engine support, in this case OPA policy engine
- Credentials are stored on disks
httpRespToErrorResponse() usually reads the http response when
the http error code is not expected to parse the json error
response in the http body, however it was never properly closing
the connection. This PR fixes the behavior.
Two handlers are added to admin API to enable profiling and disable
profiling of a server in a standalone mode, or all nodes in the
distributed mode.
/minio/admin/profiling/start/{cpu,block,mem}:
- Start profiling and return starting JSON results, e.g. one
node is offline.
/minio/admin/profiling/download:
- Stop the on-going profiling task
- Stream a zip file which contains all profiling files that can
be later inspected by go tool pprof
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.
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
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.
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 PR implements an object layer which
combines input erasure sets of XL layers
into a unified namespace.
This object layer extends the existing
erasure coded implementation, it is assumed
in this design that providing > 16 disks is
a static configuration as well i.e if you started
the setup with 32 disks with 4 sets 8 disks per
pack then you would need to provide 4 sets always.
Some design details and restrictions:
- Objects are distributed using consistent ordering
to a unique erasure coded layer.
- Each pack has its own dsync so locks are synchronized
properly at pack (erasure layer).
- Each pack still has a maximum of 16 disks
requirement, you can start with multiple
such sets statically.
- Static sets set of disks and cannot be
changed, there is no elastic expansion allowed.
- Static sets set of disks and cannot be
changed, there is no elastic removal allowed.
- ListObjects() across sets can be noticeably
slower since List happens on all servers,
and is merged at this sets layer.

- Changes related to moving admin APIs
- admin APIs now have an endpoint under /minio/admin
- admin APIs are now versioned - a new API to server the version is
added at "GET /minio/admin/version" and all API operations have the
path prefix /minio/admin/v1/<operation>
- new service stop API added
- credentials change API is moved to /minio/admin/v1/config/credential
- credentials change API and configuration get/set API now require TLS
so that credentials are protected
- all API requests now receive JSON
- heal APIs are disabled as they will be changed substantially
- Heal API changes
Heal API is now provided at a single endpoint with the ability for a
client to start a heal sequence on all the data in the server, a
single bucket, or under a prefix within a bucket.
When a heal sequence is started, the server returns a unique token
that needs to be used for subsequent 'status' requests to fetch heal
results.
On each status request from the client, the server returns heal result
records that it has accumulated since the previous status request. The
server accumulates upto 1000 records and pauses healing further
objects until the client requests for status. If the client does not
request any further records for a long time, the server aborts the
heal sequence automatically.
A heal result record is returned for each entity healed on the server,
such as system metadata, object metadata, buckets and objects, and has
information about the before and after states on each disk.
A client may request to force restart a heal sequence - this causes
the running heal sequence to be aborted at the next safe spot and
starts a new heal sequence.
This change replaces all imports of "crypto/sha256" with
"github.com/minio/sha256-simd". The sha256-simd package
is faster on ARM64 (NEON instructions) and can take advantage
of AVX-512 in certain scenarios.
Fixes#5374
After the addition of Storage Class support, readQuorum
and writeQuorum are decided on a per object basis, instead
of deployment wide static quorums.
This PR updates madmin api to remove readQuorum/writeQuorum
and add Standard storage class and reduced redundancy storage
class parity as return values. Since these parity values are
used to decide the quorum for each object.
Fixes#5378
Since the server performs automatic clean-up of multipart uploads that
have not been resumed for more than a couple of weeks, it was decided
to remove functionality to heal multipart uploads.

```
Duration for which a lock was held can be computed from the `Since`
field of `OpsLockState`. It is the difference between current time and
time at which the namespace lock was held. This change avoids
superfluous instrumentation.
`disksUnavailable` healStatus constant indicates that a given object
needs healing but one or more of disks requiring heal are offline. This
can be used by admin heal API consumers to distinguish between a
successful heal and a no-op since the outdated disks were offline.
In the algorithm to check if an object requires healing, in addition to
checking if all disks have xl.json present we should check if all parts
of the object are present and have valid blake2b checksums.
Also fixed a minor compilation error in heal-objects-list.go.
Without this fix, `mc admin heal -I` wouldn't be able to heal ongoing
uploads. `mc` depends on `ListUploadsHeal` API to identify ongoing
uploads to heal given a bucket and an object.
This API is meant for administrative tools like mc-admin to heal an
ongoing multipart upload on a Minio server. N B This set of admin
APIs apply only for Minio servers.
`github.com/minio/minio/pkg/madmin` provides a go SDK for this (and
other admin) operations. Specifically,
func HealUpload(bucket, object, uploadID string, dryRun bool) error
Sample admin API request:
POST
/?heal&bucket=mybucket&object=myobject&upload-id=myuploadID&dry-run
- Header(s): ["x-minio-operation"] = "upload"
Notes:
- bucket, object and upload-id are mandatory query parameters
- if dry-run is set, API returns success if all parameters passed are
valid.
Following is a sample list lock API request schematic,
/?lock&bucket=mybucket&prefix=myprefix&duration=holdDuration
x-minio-operation: list
The response would contain the list of locks held on mybucket matching
myprefix for a duration longer than holdDuration.
The order of marker and delimiter and in listObjectsHeal() internal function
are switched. That will give wrong result in case of a non recursive objects
heal list.
