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.
This change adds support for password-protected private keys.
If the private key is encrypted the server tries to decrypt
the key with the password provided by the env variable
MINIO_CERT_PASSWD.
Fixes#5302
- Update startup banner to print storage class in capitals. This
makes it easier to identify different storage classes available.
- Update response metadata to not send STANDARD storage class.
This is in accordance with AWS S3 behaviour.
- Update minio-go library to bring in storage class related
changes. This is needed to make transparent translation of
storage class headers for Minio S3 Gateway.
Currently, browser access information is displayed without checking
if browser enabled flag is turned off in config.json. Fixing it to
hide the information if the flag is turned off.
Fixes#5312
This change replaces the non-constant time comparison of
request signatures with a constant time implementation. This
prevents a timing attack which can be used to learn a valid
signature for a request without knowing the secret key.
Fixes#5334
This commit takes the existing remove bucket functionality written by
brendanashworth, integrates it to the current UI with a dropdown for
each bucket, and fixes small issues that were present, like the dropdown
not disappearing after the user clicks on 'Delete' for certain buckets.
This feature only deletes a bucket that is empty (that has no objects).
Fixes#4166
- Add storage class metadata validation for request header
- Change storage class header values to be consistent with AWS S3
- Refactor internal method to take only the reqd argument
HealFile() does not process the case when an empty file is lost in
some disks. Since, Reedsolomon erasure doesn't handle restoring empty
data, HealFile will create empty files similarly to CreateFile().
This adds configurable data and parity options on a per object
basis. To use variable parity
- Users can set environment variables to cofigure variable
parity
- Then add header x-amz-storage-class to putobject requests
with relevant storage class values
Fixes#4997
- Use it to send the Content-MD5 header correctly encoded to S3
Gateway
- Fixes a bug in PutObject (including anonymous PutObject) and
PutObjectPart with S3 Gateway found when testing with Mint.
Manta is an Object Storage by [Joyent](https://www.joyent.com/)
This PR adds initial support for Manta. It is intended as non-production
ready so that feedback can be obtained.
This PR allows 'minio update' to not only shows update banner
but also allows for in-place upgrades.
Updates are done safely by validating the downloaded
sha256 of the binary.
Fixes#4781
This PR handles following situations
- secure endpoints provided, server should fail to start
if TLS is not configured
- insecure endpoints provided, server starts ignoring
if TLS is configured or not.
Fixes#5251
- Adds a metadata argument to the CopyObjectPart API to facilitate
implementing encryption for copying APIs too.
- Update vendored minio-go - this version implements the
CopyObjectPart client API for use with the S3 gateway.
Fixes#4885
This check incorrectly rejects most valid filenames. The only filenames Sia
forbids are leading forward slashes and path traversal characters, but it's
better to simply allow Sia to reject invalid names on its own rather than try
to anticipate errors from Sia:
https://github.com/NebulousLabs/Sia/blob/master/doc/api/Renter.md#path-parameters-4
The problem in existing code was the following line
```
start := int(keyCrc%uint32(cardinality)) | 1
```
A given a value of N cardinality the ending result
because of the the bitwise '|' would lead to always
higher affinity to odd sequences.
As can be seen from the test cases that this can
lead to many objects being allocated the same set
of disks or atleast the first disk is an odd disk
always. This introduces a performance problem
for majority of the objects under concurrent load.
Remove `| 1` to provide a more cleaner distribution
and the new code will be.
```
start := int(keyCrc % uint32(cardinality))
```
Thanks to Krishna Srinivas for pointing out the bitwise
situation here.
This change introduces following simplified steps to follow
during config migration.
```
// Steps to move from version N to version N+1
// 1. Add new struct serverConfigVN+1 in config-versions.go
// 2. Set configCurrentVersion to "N+1"
// 3. Set serverConfigCurrent to serverConfigVN+1
// 4. Add new migration function (ex. func migrateVNToVN+1()) in config-migrate.go
// 5. Call migrateVNToVN+1() from migrateConfig() in config-migrate.go
// 6. Make changes in config-current_test.go for any test change
```
Current implementation we faked the makeBucket operations
to allow for s3 clients to behave properly. But instead
we can create a placeholder zero byte file instead, which
is a hexadecimal representation of the bucket name itself.
The Sia gateway had a bug with uploading that prevented the user's uploads
from reaching the Sia backend. The PutObject function called fsRemoveFile at
the end of the function, which didn't give the Sia backend enough time to
upload the file to the Sia network.
This adds a goroutine that watches the file upload progress and doesn't delete
the file until the upload reaches 100% complete.
Note that this solution has the limitation where if the minio process dies in
the middle of upload, it will leave orphaned files in the SIA_TEMP directory
that the user will need to remove manually.
