RFC2623 - NFS Version 2 and Version 3 Security Issues and the NFS Protocol's Use of RPCSEC_GSS and Kerberos V5: This memorandum clarifies various security issues involving the NFS protocol (Version 2 and Version 3 only) and then describes how the Version 2 and Version 3 of the NFS protocol use the RPCSEC_GSS security flavor protocol and Kerberos V5. [STANDARDS-TRACK]
RFC2624 - NFS Version 4 Design Considerations: This design considerations document is meant to present more detail than the working group charter. Specifically, it presents the areas that the working group will investigate and consider while developing a protocol specification for NFS version 4. This memo provides information for the Internet community.
RFC3010 - NFS version 4 Protocol: NFS (Network File System) version 4 is a distributed file system protocol which owes heritage to NFS protocol versions 2 [STANDARDS-TRACK]
RFC3530 - Network File System (NFS) version 4 Protocol: The Network File System (NFS) version 4 is a distributed filesystem protocol which owes heritage to NFS protocol version 2, RFC 1094, and version 3, RFC 1813. Unlike earlier versions, the NFS version 4 protocol supports traditional file access while integrating support for file locking and the mount protocol. In addition, support for strong security (and its negotiation), compound operations, client caching, and internationalization have been added. Of course, attention has been applied to making NFS version 4 operate well in an Internet environment. This document replaces RFC 3010 as the definition of the NFS version 4 protocol. [STANDARDS-TRACK]
RFC4506 - XDR: External Data Representation Standard: This document describes the External Data Representation Standard (XDR) protocol as it is currently deployed and accepted. This document obsoletes RFC 1832. [STANDARDS-TRACK]
RFC5403 - RPCSEC_GSS Version 2: This document describes version 2 of the RPCSEC_GSS protocol. Version 2 is the same as version 1 (specified in RFC 2203) except that support for channel bindings has been added. RPCSEC_GSS allows remote procedure call (RPC) protocols to access the Generic Security Services Application Programming Interface (GSS-API). [STANDARDS-TRACK]
RFC5531 - RPC: Remote Procedure Call Protocol Specification Version 2: This document describes the Open Network Computing (ONC) Remote Procedure Call (RPC) version 2 protocol as it is currently deployed and accepted. This document obsoletes RFC 1831. [STANDARDS-TRACK]
RFC5532 - Network File System (NFS) Remote Direct Memory Access (RDMA) Problem Statement: This document addresses enabling the use of Remote Direct Memory Access (RDMA) by the Network File System (NFS) protocols. NFS implementations historically incur significant overhead due to data copies on end-host systems, as well as other processing overhead. This document explores the potential benefits of RDMA to these implementations and evaluates the reasons why RDMA is especially well-suited to NFS and network file protocols in general. This memo provides information for the Internet community.
RFC5661 - Network File System (NFS) Version 4 Minor Version 1 Protocol: This document describes the Network File System (NFS) version 4 minor version 1, including features retained from the base protocol (NFS version 4 minor version 0, which is specified in RFC 3530) and protocol extensions made subsequently. Major extensions introduced in NFS version 4 minor version 1 include Sessions, Directory Delegations, and parallel NFS (pNFS). NFS version 4 minor version 1 has no dependencies on NFS version 4 minor version 0, and it is considered a separate protocol. Thus, this document neither updates nor obsoletes RFC 3530. NFS minor version 1 is deemed superior to NFS minor version 0 with no loss of functionality, and its use is preferred over version 0. Both NFS minor versions 0 and 1 can be used simultaneously on the same network, between the same client and server. [STANDARDS-TRACK]
RFC5662 - Network File System (NFS) Version 4 Minor Version 1 External Data Representation Standard (XDR) Description: This document provides the External Data Representation Standard (XDR) description for Network File System version 4 (NFSv4) minor version 1. [STANDARDS-TRACK]
RFC5663 - Parallel NFS (pNFS) Block/Volume Layout: Parallel NFS (pNFS) extends Network File Sharing version 4 (NFSv4) to allow clients to directly access file data on the storage used by the NFSv4 server. This ability to bypass the server for data access can increase both performance and parallelism, but requires additional client functionality for data access, some of which is dependent on the class of storage used. The main pNFS operations document specifies storage-class-independent extensions to NFS; this document specifies the additional extensions (primarily data structures) for use of pNFS with block- and volume-based storage. [STANDARDS-TRACK]
RFC5664 - Object-Based Parallel NFS (pNFS) Operations: Parallel NFS (pNFS) extends Network File System version 4 (NFSv4) to allow clients to directly access file data on the storage used by the NFSv4 server. This ability to bypass the server for data access can increase both performance and parallelism, but requires additional client functionality for data access, some of which is dependent on the class of storage used, a.k.a. the Layout Type. The main pNFS operations and data types in NFSv4 Minor version 1 specify a layout- type-independent layer; layout-type-specific information is conveyed using opaque data structures whose internal structure is further defined by the particular layout type specification. This document specifies the NFSv4.1 Object-Based pNFS Layout Type as a companion to the main NFSv4 Minor version 1 specification. [STANDARDS-TRACK]
RFC5665 - IANA Considerations for Remote Procedure Call (RPC) Network Identifiers and Universal Address Formats: This document lists IANA Considerations for Remote Procedure Call (RPC) Network Identifiers (netids) and RPC Universal Network Addresses (uaddrs). This document updates, but does not replace, RFC 1833. [STANDARDS-TRACK]
RFC5666 - Remote Direct Memory Access Transport for Remote Procedure Call: This document describes a protocol providing Remote Direct Memory Access (RDMA) as a new transport for Remote Procedure Call (RPC). The RDMA transport binding conveys the benefits of efficient, bulk-data transport over high-speed networks, while providing for minimal change to RPC applications and with no required revision of the application RPC protocol, or the RPC protocol itself. [STANDARDS-TRACK]
RFC5667 - Network File System (NFS) Direct Data Placement: This document defines the bindings of the various Network File System (NFS) versions to the Remote Direct Memory Access (RDMA) operations supported by the RPC/RDMA transport protocol. It describes the use of direct data placement by means of server-initiated RDMA operations into client-supplied buffers for implementations of NFS versions 2, 3, 4, and 4.1 over such an RDMA transport. [STANDARDS-TRACK]
RFC5716 - Requirements for Federated File Systems: This document describes and lists the functional requirements of a federated file system and defines related terms. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6641 - Using DNS SRV to Specify a Global File Namespace with NFS Version 4: The NFS version 4 (NFSv4) protocol provides a mechanism for a collection of NFS file servers to collaborate in providing an organization-wide file namespace. The DNS SRV Resource Record (RR) allows a simple way for an organization to publish the root of its file system namespace, even to clients that might not be intimately associated with such an organization. The DNS SRV RR can be used to join these organization-wide file namespaces together to allow construction of a global, uniform NFS file namespace. [STANDARDS-TRACK]
RFC6688 - Parallel NFS (pNFS) Block Disk Protection: Parallel NFS (pNFS) extends the Network File System version 4 (NFSv4) to enable direct client access to file data on storage devices and bypass the NFSv4 server. This can increase both performance and parallelism, but it requires additional client functionality, some of which depends upon the type of storage used. The pNFS specification for block storage (RFC 5663) describes how clients can identify the volumes used for pNFS, but this mechanism requires communication with the NFSv4 server. This document updates RFC 5663 to add a mechanism that enables identification of block storage devices used by pNFS file systems without communicating with the server. This enables clients to control access to pNFS block devices when the client initially boots, as opposed to waiting until the client can communicate with the NFSv4 server. [STANDARDS-TRACK]
RFC7204 - Requirements for Labeled NFS: This memo outlines high-level requirements for the integration of flexible Mandatory Access Control (MAC) functionality into the Network File System (NFS) version 4.2 (NFSv4.2). It describes the level of protections that should be provided over protocol components and the basic structure of the proposed system. The intent here is not to present the protocol changes but to describe the environment in which they reside.
RFC7530 - Network File System (NFS) Version 4 Protocol: The Network File System (NFS) version 4 protocol is a distributed file system protocol that builds on the heritage of NFS protocol version 2 (RFC 1094) and version 3 (RFC 1813). Unlike earlier versions, the NFS version 4 protocol supports traditional file access while integrating support for file locking and the MOUNT protocol. In addition, support for strong security (and its negotiation), COMPOUND operations, client caching, and internationalization has been added. Of course, attention has been applied to making NFS version 4 operate well in an Internet environment.; This document, together with the companion External Data Representation (XDR) description document, RFC 7531, obsoletes RFC 3530 as the definition of the NFS version 4 protocol.
RFC7531 - Network File System (NFS) Version 4 External Data Representation Standard (XDR) Description: The Network File System (NFS) version 4 protocol is a distributed file system protocol that owes its heritage to NFS protocol version 2 (RFC 1094) and version 3 (RFC 1813). Unlike earlier versions, the NFS version 4 protocol supports traditional file access while integrating support for file locking and the MOUNT protocol. In addition, support for strong security (and its negotiation), COMPOUND operations, client caching, and internationalization has been added. Of course, attention has been applied to making NFS version 4 operate well in an Internet environment.; RFC 7530 formally obsoletes RFC 3530. This document, together with RFC 7530, replaces RFC 3530 as the definition of the NFS version 4 protocol.
RFC7532 - Namespace Database (NSDB) Protocol for Federated File Systems: This document describes a file system federation protocol that enables file access and namespace traversal across collections of independently administered fileservers. The protocol specifies a set of interfaces by which fileservers with different administrators can form a fileserver federation that provides a namespace composed of the file systems physically hosted on and exported by the constituent fileservers.
RFC7533 - Administration Protocol for Federated File Systems: This document describes the administration protocol for a federated file system (FedFS) that enables file access and namespace traversal across collections of independently administered fileservers. The protocol specifies a set of interfaces by which fileservers with different administrators can form a fileserver federation that provides a namespace composed of the file systems physically hosted on and exported by the constituent fileservers.
RFC7569 - Registry Specification for Mandatory Access Control (MAC) Security Label Formats: In the past, Mandatory Access Control (MAC) systems have used very rigid policies that were implemented in particular protocols and platforms. As MAC systems become more widely deployed, additional flexibility in mechanism and policy will be required. While traditional trusted systems implemented Multi-Level Security (MLS) and integrity models, modern systems have expanded to include such technologies as type enforcement. Due to the wide range of policies and mechanisms that need to be accommodated, it is unlikely that the use of a single security label format and model will be viable.; To allow multiple MAC mechanisms and label formats to co-exist in a network, this document creates a registry of label format specifications. This registry contains label format identifiers and provides for the association of each such identifier with a corresponding extensive document outlining the exact syntax and use of the particular label format.
RFC7861 - Remote Procedure Call (RPC) Security Version 3: This document specifies version 3 of the Remote Procedure Call (RPC) security protocol (RPCSEC_GSS). This protocol provides support for multi-principal authentication of client hosts and user principals to a server (constructed by generic composition), security label assertions for multi-level security and type enforcement, structured privilege assertions, and channel bindings. This document updates RFC 5403.
RFC7862 - Network File System (NFS) Version 4 Minor Version 2 Protocol: This document describes NFS version 4 minor version 2; it describes the protocol extensions made from NFS version 4 minor version 1. Major extensions introduced in NFS version 4 minor version 2 include the following: Server-Side Copy, Application Input/Output (I/O) Advise, Space Reservations, Sparse Files, Application Data Blocks, and Labeled NFS.
RFC7863 - Network File System (NFS) Version 4 Minor Version 2 External Data Representation Standard (XDR) Description: This document provides the External Data Representation (XDR) description for NFS version 4 minor version 2.
RFC7931 - NFSv4.0 Migration: Specification Update: The migration feature of NFSv4 allows the transfer of responsibility for a single file system from one server to another without disruption to clients. Recent implementation experience has shown problems in the existing specification for this feature in NFSv4.0. This document identifies the problem areas and provides revised specification text that updates the NFSv4.0 specification in RFC 7530.
RFC8000 - Requirements for NFSv4 Multi-Domain Namespace Deployment: This document presents requirements for the deployment of the NFSv4 protocols for the construction of an NFSv4 file namespace in environments with multiple NFSv4 Domains. To participate in an NFSv4 multi-domain file namespace, the server must offer a multi-domain-capable file system and support RPCSEC_GSS for user authentication. In most instances, the server must also support identity-mapping services.
RFC8154 - Parallel NFS (pNFS) Small Computer System Interface (SCSI) Layout: The Parallel Network File System (pNFS) allows a separation between the metadata (onto a metadata server) and data (onto a storage device) for a file. The Small Computer System Interface (SCSI) layout type is defined in this document as an extension to pNFS to allow the use of SCSI-based block storage devices.
RFC8166 - Remote Direct Memory Access Transport for Remote Procedure Call Version 1: This document specifies a protocol for conveying Remote Procedure Call (RPC) messages on physical transports capable of Remote Direct Memory Access (RDMA). This protocol is referred to as the RPC-over- RDMA version 1 protocol in this document. It requires no revision to application RPC protocols or the RPC protocol itself. This document obsoletes RFC 5666.
RFC8167 - Bidirectional Remote Procedure Call on RPC-over-RDMA Transports: Minor versions of Network File System (NFS) version 4 newer than minor version 0 work best when Remote Procedure Call (RPC) transports can send RPC transactions in both directions on the same connection. This document describes how RPC transport endpoints capable of Remote Direct Memory Access (RDMA) convey RPCs in both directions on a single connection.
RFC8178 - Rules for NFSv4 Extensions and Minor Versions: This document describes the rules relating to the extension of the NFSv4 family of protocols. It covers the creation of minor versions, the addition of optional features to existing minor versions, and the correction of flaws in features already published as Proposed Standards. The rules relating to the construction of minor versions and the interaction of minor version implementations that appear in this document supersede the minor versioning rules in RFC 5661 and other RFCs defining minor versions.
RFC8267 - Network File System (NFS) Upper-Layer Binding to RPC-over-RDMA Version 1: This document specifies Upper-Layer Bindings of Network File System (NFS) protocol versions to RPC-over-RDMA version 1, thus enabling the use of Direct Data Placement. This document obsoletes RFC 5667.
RFC8275 - Allowing Inheritable NFSv4 Access Control Entries to Override the Umask: In many environments, inheritable NFSv4 Access Control Entries (ACEs) can be rendered ineffective by the application of the per-process file mode creation mask (umask). This can be addressed by transmitting the umask and create mode as separate pieces of data, allowing the server to make more intelligent decisions about the permissions to set on new files. This document proposes a protocol extension to accomplish that.
RFC8276 - File System Extended Attributes in NFSv4: This document describes an optional feature extending the NFSv4 protocol. This feature allows extended attributes (hereinafter also referred to as xattrs) to be interrogated and manipulated using NFSv4 clients. Xattrs are provided by a file system to associate opaque metadata, not interpreted by the file system, with files and directories. Such support is present in many modern local file systems. New file attributes are provided to allow clients to query the server for xattr support, with that support consisting of new operations to get and set xattrs on file system objects.
RFC8434 - Requirements for Parallel NFS (pNFS) Layout Types: This document defines the requirements that individual Parallel NFS (pNFS) layout types need to meet in order to work within the pNFS framework as defined in RFC 5661. In so doing, this document aims to clearly distinguish between requirements for pNFS as a whole and those specifically directed to the pNFS file layout. The lack of a clear separation between the two sets of requirements has been troublesome for those specifying and evaluating new layout types. In this regard, this document updates RFC 5661.
RFC8435 - Parallel NFS (pNFS) Flexible File Layout: Parallel NFS (pNFS) allows a separation between the metadata (onto a metadata server) and data (onto a storage device) for a file. The flexible file layout type is defined in this document as an extension to pNFS that allows the use of storage devices that require only a limited degree of interaction with the metadata server and use already-existing protocols. Client-side mirroring is also added to provide replication of files.
RFC8587 - NFS Version 4.0 Trunking Update: In NFS version 4.0, the fs_locations attribute informs clients about alternate locations of file systems. An NFS version 4.0 client can use this information to handle migration and replication of server file systems. This document describes how an NFS version 4.0 client can also use this information to discover an NFS version 4.0 server's trunking capabilities. This document updates RFC 7530.
RFC8797 - Remote Direct Memory Access - Connection Manager (RDMA-CM) Private Data for RPC-over-RDMA Version 1: This document specifies the format of Remote Direct Memory Access - Connection Manager (RDMA-CM) Private Data exchanged between RPC-over-RDMA version 1 peers as part of establishing a connection. The addition of the Private Data payload specified in this document is an optional extension that does not alter the RPC-over-RDMA version 1 protocol. This document updates RFC 8166.
RFC8881 - Network File System (NFS) Version 4 Minor Version 1 Protocol: This document describes the Network File System (NFS) version 4 minor version 1, including features retained from the base protocol (NFS version 4 minor version 0, which is specified in RFC 7530) and protocol extensions made subsequently. The later minor version has no dependencies on NFS version 4 minor version 0, and is considered a separate protocol.; This document obsoletes RFC 5661. It substantially revises the treatment of features relating to multi-server namespace, superseding the description of those features appearing in RFC 5661.
RFC9289 - Towards Remote Procedure Call Encryption by Default: This document describes a mechanism that, through the use of opportunistic Transport Layer Security (TLS), enables encryption of Remote Procedure Call (RPC) transactions while they are in transit. The proposed mechanism interoperates with Open Network Computing (ONC) RPC implementations that do not support it. This document updates RFC 5531.
RFC9561 - Using the Parallel NFS (pNFS) SCSI Layout to Access Non-Volatile Memory Express (NVMe) Storage Devices: This document specifies how to use the Parallel Network File System (pNFS) Small Computer System Interface (SCSI) Layout Type to access storage devices using the Non-Volatile Memory Express (NVMe) protocol family.
