The Linux NFS server allows the open to complete, which I think has been the consensus around this point in earlier discussions. Basically, activity from the holder of a delegation is not considered "conflicting". That client presumably knows about any changes and can update its cache accordingly, so we don't need to recall the delegation in this case. > 2) OPEN_DELEGATE_WRITE symmetry: > > * > If a client holds an OPEN_DELEGATE_WRITE and then the same client issues an OPEN that requires read access (or otherwise changes share access/deny modes), should the server similarly allow the operation to proceed without recall, or recall and delay? WRITE delegations should probably have been called READ_WRITE. The Linux NFS server and the spec treat them as a superset of a READ delegation. So, opening the file for READ when you hold a WRITE deleg is not considered conflicting activity. > 3) Any updates since RFC 5661: > > * > Are there clarifications or consensus updates in RFC 8881 (vs. RFC 5661) or later documents that alter expected behavior in the same-client case? > > > Thank you in advance for your time and insights.

[M] Change in ...nfs-ganesha[next]: Update delegation conflict detection logic in state_deleg_conflict_im...

by Suhas Athani (GerritHub)

Suhas Athani has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1225729?usp=email ) Change subject: Update delegation conflict detection logic in state_deleg_conflict_impl() ...................................................................... Update delegation conflict detection logic in state_deleg_conflict_impl() The implementation distinguishes between same-client and cross-client operations by comparing client IDs. - Same-client operations: Return false (no conflict, no recall needed). - Cross-client operations: Return true (conflict detected, trigger recall via `async_delegrecall()`). Skip calling fsal_reopen2() if the request is from the same client that is holding the delegation to avoid recall from cephfs.

[XS] Change in ...nfs-ganesha[next]: Fix null pointer dereference in SEQUENCE op

by Suhas Athani (GerritHub)

Suhas Athani has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1225683?usp=email ) Change subject: Fix null pointer dereference in SEQUENCE op ...................................................................... Fix null pointer dereference in SEQUENCE op Add null check for session->clientid_record before calling nfs_rpc_get_chan() to prevent NULL pointer dereference. - nfs_rpc_get_chan(session->clientid_record, 0) is called without checking if session->clientid_record is NULL. - nfs_rpc_get_chan() immediately dereferences the clientid parameter (accesses clientid->cid_minorversion), causing a NULL pointer dereference if session->clientid_record is NULL. - Line 315 later checks for NULL, but this is too late.

[L] Change in ...nfs-ganesha[next]: SAL: Allow IP based recovery from RecovDir

by Peter Schwenke (GerritHub)

Peter Schwenke has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1225678?usp=email ) Change subject: SAL: Allow IP based recovery from RecovDir ...................................................................... SAL: Allow IP based recovery from RecovDir Currently, for clustered systems the CLIDs are created in RecoveryRoot/RecovDir/nodeX/xxxxx The CLIDs for recovery are read from RecoveryRoot/aa.bb.cc.dd where aa,bb,cc,dd is an IP address. This requires the node management software to copy and delete the CLIDs. The approach here allows the CLIDs to exists in RecoveryRoot/RecovDir/ip_IP_ADDRESS_STRING where IP_ADDRESS_STRING is an address the Ganesha instance is listening on. The format is either IPv6 or IPv4. The CLIDs are created in that directory and takeover events will read from that directory.

[XS] Change in ...nfs-ganesha[next]: Add cid_confirmed_saved to nfs_client_id_t

by Peter Schwenke (GerritHub)

Peter Schwenke has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1225677?usp=email ) Change subject: Add cid_confirmed_saved to nfs_client_id_t ...................................................................... Add cid_confirmed_saved to nfs_client_id_t This is in preparation for the Virtual IP Based recovery. This required to be able to cleanup NFSv4.0 CLIDs on umount for the IP based in-situ reclaim. The indicator for being able to cleanup the CLID in fs_rm_clid() is that the client ID is in the confirmed state. We only want the CLID to be removed when the file system is no longer used by any of the nodes i.e. unmounted.
