Current (Unreleased) Release Notes

2.21.0

New Features

  • Change the behavior of the EC reconstructor to perform a fragment rebuild to a handoff node when a primary peer responds with 507 to the REPLICATE request. This changes EC to match the existing behavior of replication when drives fail. After a rebalance of EC rings (potentially removing unmounted/failed devices), it’s most IO efficient to run in handoffs_only mode to avoid unnecessary rebuilds.

  • O_TMPFILE support is now detected by attempting to use it instead of looking at the kernel version. This allows older kernels with backported patches to take advantage of the O_TMPFILE functionality.

  • Add slo_manifest_hook callback to allow other middlewares to impose additional constraints on or make edits to SLO manifests before being written. For example, a middleware could enforce minimum segment size or insert data segments.

  • Fixed an issue with multi-region EC policies that caused the EC reconstructor to constantly attempt cross-region rebuild traffic.

  • Fixed an issue where S3 API v4 signatures would not be validated against the body of the request, allowing a replay attack if request headers were captured by a malicious third party.

  • Display crypto data/metadata details in swift-object-info.

  • formpost can now accept a content-encoding parameter.

  • Fixed an issue where multipart uploads with the S3 API would sometimes report an error despite all segments being upload successfully.

  • Multipart object segments are now actually deleted when the multipart object is deleted via the S3 API.

  • Swift now returns a 503 (instead of a 500) when an account auto-create fails.

  • Fixed a bug where encryption would store the incorrect key metadata if the object name starts with a slash.

  • Fixed an issue where an object server failure during a client download could leave an open socket between the proxy and client.

  • Fixed an issue where deleted EC objects didn’t have their on-disk directories cleaned up. This would cause extra resource usage on the object servers.

  • Fixed issue where bulk requests using xml and expect 100-continue would return a malformed HTTP response.

  • Various other minor bug fixes and improvements.
