Description Casey Bodley 2017-07-18 19:58:19 UTC 
Description of problem:

Objects encrypted with the SSE-KMS mode sync to other zones, but are stored in their unencrypted form. Because they retain their encryption attributes, attempts to read them from a secondary zone will decrypt the data again, returning garbage data to the client.


How reproducible:

All objects encrypted with SSE-KMS in a multisite configuration.


Steps to Reproduce:
1. Set up a multisite configuration with two zones, including these additional values in ceph.conf:
[client]
  rgw crypt require ssl = false
  rgw crypt s3 kms encryption keys = testkey=YmluCmJvb3N0CmJvb3N0LWJ1aWxkCmNlcGguY29uZgo=

2. Create a bucket on the primary zone
3. Upload an object (containing readable text) to that bucket on the primary zone, using these additional request headers:
  x-amz-server-side-encryption: aws:kms
  x-amz-server-side-encryption-aws-kms-key-id: testkey

Actual results:

The object syncs to the secondary zone, but its data does not match the readable text uploaded to the primary zone.

Expected results:

The synced object is stored on the secondary zone in its encrypted form. When read, the decrypted object data is returned to the client.

Additional info:

The sync request should fetch the object in its encrypted form.
