This PR simplifies the code to avoid tracking
any running usage events. This PR also brings
in an upper threshold of upto 1 minute suspend
the usage function after which the usage would
proceed without waiting any longer.
This commit introduces a new crypto package providing
AWS S3 related cryptographic building blocks to implement
SSE-S3 (master key or KMS) and SSE-C.
This change only adds some basic functionallity esp.
related to SSE-S3 and documents the general approach
for SSE-S3 and SSE-C.
disk usage crawling is not needed when a tenant
is not sharing the same disk for multiple other
tenants. This PR adds an optimization when we
see a setup uses entire disk, we simply rely on
statvfs() to give us total usage.
This PR also additionally adds low priority
scheduling for usage check routine, such that
other go-routines blocked will be automatically
unblocked and prioritized before usage.
Minio server returns 403 (access denied) for head requests to prefixes
without trailing "/", this is different from S3 behaviour. S3 returns
404 in such cases.
Fixes#6080
This commit prevents complete server failures caused by
`logger.CriticalIf` calls. Instead of calling `os.Exit(1)`
the function now executes a panic with a special value
indicating that a critical error happend. At the top HTTP
handler layer panics are recovered and if its a critical
error the client gets an InternalServerError status code.
Further this allows unit tests to cover critical-error code
paths.
Add compile time GOROOT path to the list of prefix
of file paths to be removed.
Add webhandler function names to the slice that
stores function names to terminate logging.
During startup until the object layer is initialized
logger is disabled to provide for a cleaner UI error
message. CriticalIf is disabled, use FatalIf instead.
Also never call os.Exit(1) on running servers where
you can return error to client in handlers.
This commit limits the amount of memory allocated by the
S3 Multi-Object-Delete-API. The server used to allocate as
many bytes as provided by the client using Content-Length.
S3 specifies that the S3 Multi-Object-Delete-API can delete
at most 1000 objects using a single request.
(See: https://docs.aws.amazon.com/AmazonS3/latest/API/multiobjectdeleteapi.html)
Since the maximum S3 object name is limited to 1024 bytes the
XML body sent by the client can only contain up to 1000 * 1024
bytes (excluding XML format overhead).
This commit limits the size of the parsed XML for the S3
Multi-Object-Delete-API to 2 MB. This fixes a DoS
vulnerability since (auth.) clients, MitM-adversaries
(without TLS) and un-auth. users accessing buckets allowing
multi-delete by policy can kill the server.
This behavior is similar to the AWS-S3 implementation.
This PR adds CopyObject support for objects residing in buckets
in different Minio instances (where Minio instances are part of
a federated setup).
Also, added support for multiple Minio domain IPs. This is required
for distributed deployments, where one deployment may have multiple
nodes, each with a different public IP.
Buckets already present on a Minio server before it joins a
bucket federated deployment will now be added to etcd during
startup. In case of a bucket name collision, admin is informed
via Minio server console message.
Added configuration migration for configuration stored in etcd
backend.
Also, environment variables are updated and ListBucket path style
request is no longer forwarded.
Added support for new RPC support using HTTP POST. RPC's
arguments and reply are Gob encoded and sent as HTTP
request/response body.
This patch also removes Go RPC based implementation.
With the implementation of dummy GET ACL handlers,
tools like s3cmd perform few operations which causes
the ACL call to be invoked. Make sure that in our
router configuration GET?acl comes before actual
GET call to facilitate this dummy call.
tests were written in the manner by editing internal
variables of fsObjects to mimic certain behavior from
APIs, but this is racy when an active go-routine is
reading from the same variable.
Make sure to terminate the go-routine if possible for
these tests.
The current problem is that when you invoke
```
mc admin info myminio | head -1
● localhost:9000
```
This output is incorrect as the expected output should be
```
mc admin info myminio | head -1
● 192.168.1.17:9000
```
