From 1c73b9d24f804935dbb06527b768f8f068c93472 Mon Sep 17 00:00:00 2001 From: Scott Mayhew Date: Thu, 2 May 2019 13:32:12 -0400 Subject: nfsd: update callback done processing Instead of having the convention where individual nfsd4_callback_ops->done operations return -1 to indicate the callback path is down, move the check to nfsd4_cb_done. Only mark the callback path down on transport-level errors, not NFS-level errors. The existing logic causes the server to set SEQ4_STATUS_CB_PATH_DOWN just because the client returned an error to a CB_RECALL for a delegation that the client had already done a FREE_STATEID for. But clearly that error doesn't mean that there's anything wrong with the backchannel. Additionally, handle NFS4ERR_DELAY in nfsd4_cb_recall_done. The client returns NFS4ERR_DELAY if it is already in the process of returning the delegation. Signed-off-by: Scott Mayhew Signed-off-by: J.
