Hi Tomaž, I just updated the PR to support the S3 RGW storage driver at [1]
The Libcloud support in Ceph was upstream several weeks ago [2] and it would be great having this PR upstream in Libcloud to be used by the Ceph community. This PR could help us to improve the coverage with the combo PUT + UNSIGNED-PAYLOAD + Auth header under AWS4 auth used by Libcloud to sign uploads via S3 in Ceph. Thanks, Javier -- [1] https://github.com/apache/libcloud/pull/786 [2] https://github.com/ceph/ceph/pull/8601
