Description Casey Bodley 2017-07-18 19:46:36 UTC
Description of problem:

Objects encrypted with the SSE-C mode do not sync to other zones.


How reproducible:

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


Steps to Reproduce:

1. Set up a multisite configuration with two zones, including this additional value in ceph.conf:
[client]
  rgw crypt require ssl = false

2. Create a bucket on the primary zone
3. Upload an object to that bucket on the primary zone, using these additional request headers:
  x-amz-server-side-encryption-customer-algorithm: AES256
  x-amz-server-side-encryption-customer-key: pO3upElrwuEXSoFwCfnZPdSsmt/xWeFa0N9KgDijwVs=
  x-amz-server-side-encryption-customer-key-md5: DWygnHRtgiJ77HCm+1rvHw==

Actual results:

The object never syncs to the secondary zone. The radosgw log will contain errors like 'data sync: ERROR: failed to sync object: BUCKET:563951e3-8440-4b01-aa6d-58b4fea0e5d0.4110.1/fooo' (where bucket name is BUCKET and object name is fooo).

Expected results:

The object syncs to the secondary zone in its encrypted form. The decrypted object can be read from the secondary zone with a GET request that includes the same x-amz-server-side-encryption- headers used to upload.

Additional info:

Multisite sync requests are rejected with '400 Bad Request' because they do not provide the x-amz-server-side-encryption- headers needed to decrypt the object data. This is enforced by rgw_s3_prepare_decrypt().
