Close the replication-header trust flaw that allowed ordinary PutObject and CopyObject requests to smuggle X-Minio-Replication-* headers into X-Minio-Internal-* SSE metadata and write objects into an unreadable state. Stop accepting replication-only metadata in the default extraction path, restore it only after a trusted replication write has passed ReplicateObjectAction, and tighten CopyObject by sanitizing replication-only request headers before metadata, precondition, and SSE-C source handling consume them. Also gate replica status writes on the same trusted replication path and restore replication SSE metadata in multipart and snowball upload flows so legitimate replication continues to work.
Add focused regression coverage for untrusted PUT and COPY header poisoning at the handler layer, plus helper tests for trusted vs untrusted metadata extraction and CopyObject header sanitization. Validate the new tests against both the patched tree and the vulnerable HEAD baseline, and confirm with live server before/after runs that malicious PUT/COPY requests no longer turn objects unreadable.

`go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...` executed.
`go generate ./...` ran afterwards to keep generated.
When the encryption and compression are both enabled, the
the server will avoid compressing the data for no apparent reason
This commit will enable it and update unit tests.
If `SkipReader` is called with a small initial buffer it may be doing a huge number if Reads to skip the requested number of bytes. If a small buffer is provided grab a 32K buffer and use that.
Fixes slow execution of `testAPIGetObjectWithMPHandler`.
Bonuses:
* Use `-short` with `-race` test.
* Do all suite test types with `-short`.
* Enable compressed+encrypted in `testAPIGetObjectWithMPHandler`.
* Disable big file tests in `testAPIGetObjectWithMPHandler` when using `-short`.
- handle errFileCorrupt properly
- micro-optimization of sending done() response quicker
to close the goroutine.
- fix logger.Event() usage in a couple of places
- handle the rest of the client to return a different error other than
lastErr() when the client is closed.
A huge number of goroutines would build up from various monitors
When creating test filesystems provide a context so they can shut down when no longer needed.
Main motivation is move towards a common backend format
for all different types of modes in MinIO, allowing for
a simpler code and predictable behavior across all features.
This PR also brings features such as versioning, replication,
transitioning to single drive setups.
- remove some duplicated code
- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed
- using filepath.ToSlash() use when needed
- remove all non-Go style comments from the codebase

This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
Cases where we have applications making request
for `//` in object names make sure that all
are normalized to `/` and all such requests that
are prefixed '/' are removed. To ensure a
consistent view from all operations.
```
mc admin config set alias/ storage_class standard=EC:3
```
should only succeed if parity ratio is valid for all
server pools, if not we should fail proactively.
This PR also needs to bring other changes now that
we need to cater for variadic drive counts per pool.
Bonus fixes also various bugs reproduced with
- GetObjectWithPartNumber()
- CopyObjectPartWithOffsets()
- CopyObjectWithMetadata()
- PutObjectPart,PutObject with truncated streams
This commit refactors the code in `cmd/crypto`
and separates SSE-S3, SSE-C and SSE-KMS.
This commit should not cause any behavior change
except for:
- `IsRequested(http.Header)`
which now returns the requested type {SSE-C, SSE-S3,
SSE-KMS} and does not consider SSE-C copy headers.
However, SSE-C copy headers alone are anyway not valid.
additionally also configure http2 healthcheck
values to quickly detect unstable connections
and let them timeout.
also use single transport for proxying requests
partNumber was miscalculting the start and end of parts when partNumber
query is specified in the GET request. This commit fixes it and also
fixes the ContentRange header in that case.
- x-amz-storage-class specified CopyObject
should proceed regardless, its not a precondition
- sourceVersionID is specified CopyObject should
proceed regardless, its not a precondition
- Implement a new xl.json 2.0.0 format to support,
this moves the entire marshaling logic to POSIX
layer, top layer always consumes a common FileInfo
construct which simplifies the metadata reads.
- Implement list object versions
- Migrate to siphash from crchash for new deployments
for object placements.
Fixes#2111
