( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1224232?usp=email ) Change subject: Support for NFSv4.2 Delegation Timestamp Extensions (RFC 9754) ...................................................................... Support for NFSv4.2 Delegation Timestamp Extensions (RFC 9754) This PR implements server support for NFSv4.2 delegation timestamp attributes as required and verified by the DELEG24 pynfs test. All new attributes, types, and logic only apply to NFSv4.2 clients and are version-gated for safety and backward compatibility. • Defined new NFSv4.2 attributes/constants and their XDR types. New delegation related attributes - FATTR4_TIME_DELEG_MODIFY, FATTR_TIME_DELEG_ACCESS, FATTR4_OPEN_ARGUMENTS. • Updated server attribute handling and encoding to expose/handle these attributes only for v4.2 clients. • Added support for the OPEN flag and open_arguments structure for delegation timestamp negotiation. • Updated the CB_GETATTR response handling with logging and state management. With these changes DELEG24 and DELEG25 test cases are passing when introduced with client retry mechanism. DELEG24 tests CB_GETATTR without the attribute changes. DELEG25 tests CB_GETATTR with the attribute changes (retry on NFS4ERR_DELAY).
