This PR fixes a regression introduced in 8eb838bf91
where hashing technique was used on prefixes to get the right set
to perform the operation, this is not correct since prefixes and
their corresponding keys might hash to a different value depending
on the key length.
For prefixes/directories we should look everywhere to support proper
quorum based listing.
Fixes#6293
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
Modified the LogIf function to log only if the error passed
is not on the ignored errors list.
Currently, only disk not found error is added to the list.
Added a new function in logger package called LogAlwaysIf,
which will print on any error.
Fixes#5997
This commit adds support for detecting SSE-KMS headers.
The server should be able to detect SSE-KMS headers to
at least fail such S3 requests with not implemented.
When a S3 client sends a GET Object with a range header, 206 http
code is returned indicating success, however the call of the object
layer's GetObject() inside the handler can return an error and will lead
to writing an XML error message, which is obviously wrong since
we already sent 206 http code. So in the case, we just stop sending
data to the S3 client, this latter can still detect if there is no
error when comparing received data with Content-Length header
in the Get Object response.
When an S3 client issues a GET request with range specified, Minio
server returns some partial data with 206 http code. The latter
is sent in MINIO_HTTP_TRACE output which is incorrect. This PR
fixes the issue.
ANSI colors do not work on dumb terminals, in situations
when minio is running as a service under systemd.
This PR ensures we turn off color in those situations.
This is to avoid serializing RPC contention on ongoing
parallel operations, the blocking profile indicating
all calls were being serialized through setRetryTicker.
This commit adds the crypto.* errors to the
`toAPIErrorCode` switch. Further this commit adds an S3
API error code returned whenever the client specifes a
SSE-S3 request with an invalid algorithm parameter.
Fixes#6238
globalPolicySys used to be initialized in fs/xl layer. The referenced
commit moved this logic to server/gateway initialization,but a check
to avoid double initialization prevented globalPolicySys to be loaded
from disk for NAS.
fixes regression from commit be1700f595
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.
POST mime/multipart upload style can have filename value optional
which leads to implementation issues in Go releases in their
standard mime/multipart library.
When `filename` doesn't exist Go doesn't update `form.File` which
we rely on to extract the incoming file data, strangely when `filename`
is not specified this data is buffered in memory and is now part of
`form.Value` instead of `form.File` which creates an inconsistent
behavior.
This PR tries to fix this in our code for the time being, but ideal PR
would be to fix the upstream mime/multipart library to handle the
above situation consistently.
This commit adds a `fmt.Stringer` implementation for
SSE-S3 and SSE-C. The string representation is the
domain used for object key sealing.
See: `ObjectKey.Seal(...)` and `ObjectKey.Unseal(...)`

Our posix.go implementation did not handle I/O errors
properly on the disks, this led to situations where
top-level callers such as ListObjects might return early
without even verifying all the available disks.
This commit tries to address this in Kubernetes, drbd/nbd based
persistent volumes which can disconnect under load and
result in the situations with disks return I/O errors.
This commit also simplifies listing operation, listing
never returns any error. We can avoid this since we pretty
much ignore most of the errors anyways. When objects are
accessed directly we return proper errors.
* crypto: add support for parsing SSE-C/SSE-S3 metadata
This commit adds support for detecting and parsing
SSE-C/SSE-S3 object metadata. With the `IsEncrypted`
functions it is possible to determine whether an object
seems to be encrypted. With the `ParseMetadata` functions
it is possible to validate such metadata and extract the
SSE-C/SSE-S3 related values.
It also fixes some naming issues.
* crypto: add functions for creating SSE object metadata
This commit adds functions for creating SSE-S3 and
SSE-C metadata. It also adds a `CreateMultipartMetadata`
for creating multipart metadata.
For all functions unit tests are included.
Since implementing `pwrite` like implementation would
require a more complex code than background append
implementation, it is better to keep the current code
as is and not implement `pwrite` based functionality.
