This change adds documentation about PKCS-8 vs PKCS-1 pitfalls. It
also provides a command to convert encrypted PKCS-8 RSA keys to
encrypted PKCS-1 RSA keys.
Fixes#5453
- 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.
In current implementation we used as many dsync clients
as per number of endpoints(along with path) which is not
the expected implementation. The implementation of Dsync
was expected to be just for the endpoint Host alone such
that if you have 4 servers and each with 4 disks we need
to only have 4 dsync clients and 4 dsync servers. But
we currently had 8 clients, servers which in-fact is
unexpected and should be avoided.
This PR brings the implementation back to its original
intention. This issue was found #5160
This change is a simplification over existing
code since it is not required to have a separate
RPCClient structure instead keep authRPCClient can
do the same job.
There is no code which directly uses netRPCClient(),
keeping authRPCClient is better and simpler. This
simplication also allows for removal of multiple
levels of locking code per object.
Observed in #5160
This change adds the HighwayHash256 PRF as bitrot protection / detection
algorithm. Since HighwayHash256 requires a 256 bit we generate a random
key from the first 100 decimals of π - See nothing-up-my-sleeve-numbers.
This key is fixed forever and tied to the HighwayHash256 bitrot algorithm.
Fixes#5358
The problem was after the globalServiceDoneCh receives a
message, we cleanly stop the ticker as expected. But the
go-routine where the `select` loop is running is never
returned from. The stage at which point this may occur
i.e server is being restarted, doesn't seriously affect
servers usage. But any build up like this on server has
consequences as the new functionality would come in future.
With storage class support, the free and total space
reported in Minio XL startup banner should be based on
totalDisks - standardClassParityDisks, instead of totalDisks/2.
fixes#5416
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
Internally, triton-go, what manta minio is built on, changed it's internal
error handling. This means we no longer need to unwrap specific error types
This doesn't change any manta minio functionality - it just changes how errors are
handled internally and adds a wrapper for a 404 error
This change fixes an authentication bypass attack against the
minio Admin-API. Therefore the Admin-API rejects now all types of
requests except valid signature V2 and signature V4 requests - this
includes signature V2/V4 pre-signed requests.
Fixes#5411
This fix removes logrus package dependency and refactors the console
logging as the only logging mechanism by removing file logging support.
It rearranges the log message format and adds stack trace information
whenever trace information is not available in the error structure.
It also adds `--json` flag support for server logging.
When minio server is started with `--json` flag, all log messages are
displayed in json format, with no start-up and informational log
messages.
Fixes#5265#5220#5197
This commit fixes the order of the functions inside the selectPrefix
function due to the fact that, as multiple files were being uploaded,
the resetObjects function (that clears the object list) ran repeatedly
for each of these objects, right before the appendObjects function (that
appends the objects being uploaded to the current list of objects) also
ran for all of these objects. This caused all the objects in the bucket
to be repeated in the list for the number of objects that were dragged
into the dropzone.
Under any concurrent removeObjects in progress
might have removed the parents of the same prefix
for which there is an ongoing putObject request.
An inconsistent situation may arise as explained
below even under sufficient locking.
PutObject is almost successful at the last stage when
a temporary file is renamed to its actual namespace
at `a/b/c/object1`. Concurrently a RemoveObject is
also in progress at the same prefix for an `a/b/c/object2`.
To create the object1 at location `a/b/c` PutObject has
to create all the parents recursively.
```
a/b/c - os.MkdirAll loops through has now created
'a/' and 'b/' about to create 'c/'
a/b/c/object2 - at this point 'c/' and 'object2'
are deleted about to delete b/
```
Now for os.MkdirAll loop the expected situation is
that top level parent 'a/b/' exists which it created
, such that it can create 'c/' - since removeObject
and putObject do not compete for lock due to holding
locks at different resources. removeObject proceeds
to delete parent 'b/' since 'c/' is not yet present,
once deleted 'os.MkdirAll' would receive an error as
syscall.ENOENT which would fail the putObject request.
This PR tries to address this issue by implementing
a safer/guarded approach where we would retry an operation
such as `os.MkdirAll` and `os.Rename` if both operations
observe syscall.ENOENT.
Fixes#5254
This change restircts the supported cipher suites of the minio server.
The server only supports AEAD ciphers (Chacha20Poly1305 and
AES-GCM)
The supported cipher suites are:
- tls.TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305
- tls.TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305
- tls.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
- tls.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
- tls.TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
- tls.TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
Fixes#5244 and #5291
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.
If STANDARD storage class is set before starting up Minio server,
but x-amz-storage-class metadata field is not set in a PutObject
request, Minio server defaults to N/2 data and N/2 parity disks.
This PR changes the behaviour to use data and parity disks set in
STANDARD storage class, even if x-amz-storage-class metadata
field is not present in PutObject requests.
- Return error when the config JSON has duplicate keys (fixes#5286)
- Limit size of configuration file provided to 256KiB - this prevents
another form of DoS
Remove the requirement for IssuedAt claims from JWT
for now, since we do not currently have a way to provide
a leeway window for validating the claims. Expiry does
the same checks as IssuedAt with an expiry window.
We do not need it right now since we have clock skew check
in our RPC layer to handle this correctly.
rpc-common.go
```
func isRequestTimeAllowed(requestTime time.Time) bool {
// Check whether request time is within acceptable skew time.
utcNow := UTCNow()
return !(requestTime.Sub(utcNow) > rpcSkewTimeAllowed ||
utcNow.Sub(requestTime) > rpcSkewTimeAllowed)
}
```
Once the PR upstream is merged https://github.com/dgrijalva/jwt-go/pull/139
We can bring in support for leeway later.
Fixes#5237
x-amz-content-sha256 can be optional for any AWS signature v4
requests, make sure to skip sha256 calculation when payload
checksum is not set.
Here is the overall expected behavior
** Signed request **
- X-Amz-Content-Sha256 is set to 'empty' or some 'value' or its
not 'UNSIGNED-PAYLOAD'- use it to validate the incoming payload.
- X-Amz-Content-Sha256 is set to 'UNSIGNED-PAYLOAD' - skip checksum verification
- X-Amz-Content-Sha256 is not set we use emptySHA256
** Presigned request **
- X-Amz-Content-Sha256 is set to 'empty' or some 'value' or its
not 'UNSIGNED-PAYLOAD'- use it to validate the incoming payload
- X-Amz-Content-Sha256 is set to 'UNSIGNED-PAYLOAD' - skip checksum verification
- X-Amz-Content-Sha256 is not set we use 'UNSIGNED-PAYLOAD'
Fixes#5339
This PR updates the behaviour to print relevant error message
if storage class is set in config.json for gateway
This PR also fixes the case where storage class set via
environment variables is not parsed properly into config.json.
Save http trace to a file instead of displaying it onto the console.
the environment variable MINIO_HTTP_TRACE will be a filepath instead
of a boolean.
This to handle the scenario where both json and http tracing are
turned on. In that case, both http trace and json output are displayed
on the screen making the json not parsable. Loging this trace onto
a file helps us avoid that scenario.
Fixes#5263
Manta has the ability to allow users to authenticate with a
username other than the main account. We want to expose
this functionality to minio manta gateway.
