Ceph » rgw

Seen on test ceph cluster running v14.2.9 in containers (v4.0.12-stable-4.0-nautilus-centos-7).

We can successfully read/write S3 objects to RGWs using SSE-C, and also use x-amz-copy-source to copy objects, as per documentation:

https://docs.ceph.com/docs/nautilus/radosgw/encryption/#customer-provided-keys
https://docs.ceph.com/docs/nautilus/radosgw/s3/objectops/#copy-object

Expectation:
------------
RGW requests with `x-amz-server-side-encryption-customer` fields and `x-amz-copy-source` return success.

Actual:
-------
Requests that combine both headers i.e. copying an encrypted object, fail with a 501 NotImplemented response:
