Subject: rgw: return ERR_NO_SUCH_BUCKET early while evaluating bucket policy
X-Git-Tag: v13.2.7~290^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=00abdf56e5ac726377f297dd87c9f078e00767af;p=ceph.git

rgw: return ERR_NO_SUCH_BUCKET early while evaluating bucket policy

Right now we create a ERR_NO_SUCH_BUCKET ret code but continue further
processing. Since this ret code isn't returned at any stage we end up creating a
bucket instance anyway which shouldn't happen and then succeeding the client
call in cases like put bucket versioning. Return an error code early in these
cases
