From Jeff Layton <jlayton(a)redhat.com&gt;: Jeff Layton has uploaded this change for review. ( https://review.gerrithub.io/426589 Change subject: FSAL_CEPH: open file as root for COMMIT purposes ...................................................................... FSAL_CEPH: open file as root for COMMIT purposes Kenneth reported that he was seeing problems copying large, read only files to a share as an unprivileged user. The final COMMIT call would get back a permissions error. Since we don't have a stateid to use as a hint, we have to use the global fd to issue a commit. In many situations we won't have it open for write already, so we need to perform an open. If the file has gone r/o though, we can't do that with the creds sent in the RPC. Switch to using root creds for the when we're opening the file for a COMMIT call. We check the permissions at the protocol layer already and we're just using it to issue an fsync, so this should be safe.
