1. Introduction
This document specifies version 2 of the message protocol used in ONC
Remote Procedure Call (RPC). The message protocol is specified with
the eXternal Data Representation (XDR) language [RFC4506]. This
document assumes that the reader is familiar with XDR. It does not
attempt to justify remote procedure call systems or describe their
use. The paper by Birrell and Nelson [XRPC] is recommended as an
excellent background for the remote procedure call concept.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. Changes since RFC 1831
This document obsoletes [RFC1831] as the authoritative document
describing RPC, without introducing any over-the-wire protocol
changes. The main changes from RFC 1831 are:
o Addition of an Appendix that describes how an implementor can
request new RPC program numbers, authentication flavor numbers,
and authentication status numbers from IANA, rather than from Sun
Microsystems
o Addition of an "IANA Considerations" section that describes past
number assignment policy and how IANA is intended to assign them
in the future
o Clarification of the RPC Language Specification to match current
usage
o Enhancement of the "Security Considerations" section to reflect
experience with strong security flavors
o Specification of new authentication errors that are in common use
in modern RPC implementations
o Updates for the latest IETF intellectual property statements
3. Terminology
This document discusses clients, calls, servers, replies, services,
programs, procedures, and versions. Each remote procedure call has
two sides: an active client side that makes the call to a server
side, which sends back a reply. A network service is a collection of
one or more remote programs. A remote program implements one or more
remote procedures; the procedures, their parameters, and results are
documented in the specific program's protocol specification. A
server may support more than one version of a remote program in order
to be compatible with changing protocols.
For example, a network file service may be composed of two programs.
One program may deal with high-level applications such as file system
access control and locking. The other may deal with low-level file
input and output and have procedures like "read" and "write". A
client of the network file service would call the procedures
associated with the two programs of the service on behalf of the
client.
The terms "client" and "server" only apply to a particular
transaction; a particular hardware entity (host) or software entity
(process or program) could operate in both roles at different times.
For example, a program that supplies remote execution service could
also be a client of a network file service.
4. The RPC Model
The ONC RPC protocol is based on the remote procedure call model,
which is similar to the local procedure call model. In the local
case, the caller places arguments to a procedure in some well-
specified location (such as a register window). It then transfers
control to the procedure, and eventually regains control. At that
point, the results of the procedure are extracted from the well-
specified location, and the caller continues execution.
The remote procedure call model is similar. One thread of control
logically winds through two processes: the caller's process and a
server's process. The caller first sends a call message to the
server process and waits (blocks) for a reply message. The call
message includes the procedure's parameters, and the reply message
includes the procedure's results. Once the reply message is
received, the results of the procedure are extracted, and the
caller's execution is resumed.
On the server side, a process is dormant awaiting the arrival of a
call message. When one arrives, the server process extracts the
procedure's parameters, computes the results, sends a reply message,
and then awaits the next call message.
In this model, only one of the two processes is active at any given
time. However, this model is only given as an example. The ONC RPC
protocol makes no restrictions on the concurrency model implemented,
and others are possible. For example, an implementation may choose
to have RPC calls be asynchronous so that the client may do useful
work while waiting for the reply from the server. Another
possibility is to have the server create a separate task to process
an incoming call so that the original server can be free to receive
other requests.
There are a few important ways in which remote procedure calls differ
from local procedure calls.
o Error handling: failures of the remote server or network must be
handled when using remote procedure calls.
o Global variables and side effects: since the server does not have
access to the client's address space, hidden arguments cannot be
passed as global variables or returned as side effects.
o Performance: remote procedures usually operate at one or more
orders of magnitude slower than local procedure calls.
o Authentication: since remote procedure calls can be transported
over unsecured networks, authentication may be necessary.
Authentication prevents one entity from masquerading as some other
entity.
The conclusion is that even though there are tools to automatically
generate client and server libraries for a given service, protocols
must still be designed carefully.
5. Transports and Semantics
The RPC protocol can be implemented on several different transport
protocols. The scope of the definition of the RPC protocol excludes
how a message is passed from one process to another, and includes
only the specification and interpretation of messages. However, the
application may wish to obtain information about (and perhaps control
over) the transport layer through an interface not specified in this
document. For example, the transport protocol may impose a
restriction on the maximum size of RPC messages, or it may be
stream-oriented like TCP [RFC0793] with no size limit. The client
and server must agree on their transport protocol choices.
It is important to point out that RPC does not try to implement any
kind of reliability and that the application may need to be aware of
the type of transport protocol underneath RPC. If it knows it is
running on top of a reliable transport such as TCP, then most of the
work is already done for it. On the other hand, if it is running on
top of an unreliable transport such as UDP [RFC0768], it must
implement its own time-out, retransmission, and duplicate detection
policies as the RPC protocol does not provide these services.
Because of transport independence, the RPC protocol does not attach
specific semantics to the remote procedures or their execution
requirements. Semantics can be inferred from (but should be
explicitly specified by) the underlying transport protocol. For
example, consider RPC running on top of an unreliable transport such
as UDP. If an application retransmits RPC call messages after time-
outs, and does not receive a reply, it cannot infer anything about
the number of times the procedure was executed. If it does receive a
reply, then it can infer that the procedure was executed at least
once.
A server may wish to remember previously granted requests from a
client and not regrant them, in order to insure some degree of
execute-at-most-once semantics. A server can do this by taking
advantage of the transaction ID that is packaged with every RPC
message. The main use of this transaction ID is by the client RPC
entity in matching replies to calls. However, a client application
may choose to reuse its previous transaction ID when retransmitting a
call. The server may choose to remember this ID after executing a
call and not execute calls with the same ID, in order to achieve some
degree of execute-at-most-once semantics. The server is not allowed
to examine this ID in any other way except as a test for equality.
On the other hand, if using a "reliable" transport such as TCP, the
application can infer from a reply message that the procedure was
executed exactly once, but if it receives no reply message, it cannot
assume that the remote procedure was not executed. Note that even if
a connection-oriented protocol like TCP is used, an application still
needs time-outs and reconnections to handle server crashes.
There are other possibilities for transports besides datagram- or
connection-oriented protocols. For example, a request-reply protocol
such as [VMTP] is perhaps a natural transport for RPC. ONC RPC
currently uses both TCP and UDP transport protocols. Section 11
("Record Marking Standard") describes the mechanism employed by ONC
RPC to utilize a connection-oriented, stream-oriented transport such
as TCP. The mechanism by which future transports having different
structural characteristics should be used to transfer ONC RPC
messages should be specified by means of a Standards Track RFC, once
such additional transports are defined.
6. Binding and Rendezvous Independence
The act of binding a particular client to a particular service and
transport parameters is NOT part of this RPC protocol specification.
This important and necessary function is left up to some higher-level
software.
Implementors could think of the RPC protocol as the jump-subroutine
instruction (JSR) of a network; the loader (binder) makes JSR useful,
and the loader itself uses JSR to accomplish its task. Likewise, the
binding software makes RPC useful, possibly using RPC to accomplish
this task.
7. Authentication
The RPC protocol provides the fields necessary for a client to
identify itself to a service, and vice-versa, in each call and reply
message. Security and access control mechanisms can be built on top
of this message authentication. Several different authentication
protocols can be supported. A field in the RPC header indicates
which protocol is being used. More information on specific
authentication protocols is in Section 8.2, "Authentication,
Integrity and Privacy".
8. RPC Protocol Requirements
The RPC protocol must provide for the following:
o Unique specification of a procedure to be called
o Provisions for matching response messages to request messages
o Provisions for authenticating the caller to service and vice-versa
Besides these requirements, features that detect the following are
worth supporting because of protocol roll-over errors, implementation
bugs, user error, and network administration:
o RPC protocol mismatches
o Remote program protocol version mismatches
o Protocol errors (such as misspecification of a procedure's
parameters)
o Reasons why remote authentication failed
o Any other reasons why the desired procedure was not called
8.1. RPC Programs and Procedures
The RPC call message has three unsigned-integer fields -- remote
program number, remote program version number, and remote procedure
number -- that uniquely identify the procedure to be called. Program
numbers are administered by a central authority (IANA). Once
implementors have a program number, they can implement their remote
program; the first implementation would most likely have the version
number 1 but MUST NOT be the number zero. Because most new protocols
evolve, a "version" field of the call message identifies which
version of the protocol the caller is using. Version numbers enable
support of both old and new protocols through the same server
process.
The procedure number identifies the procedure to be called. These
numbers are documented in the specific program's protocol
specification. For example, a file service's protocol specification
may state that its procedure number 5 is "read" and procedure number
12 is "write".
Just as remote program protocols may change over several versions,
the actual RPC message protocol could also change. Therefore, the
call message also has in it the RPC version number, which is always
equal to 2 for the version of RPC described here.
The reply message to a request message has enough information to
distinguish the following error conditions:
o The remote implementation of RPC does not support protocol version
2. The lowest and highest supported RPC version numbers are
returned.
o The remote program is not available on the remote system.
o The remote program does not support the requested version number.
The lowest and highest supported remote program version numbers
are returned.
o The requested procedure number does not exist. (This is usually a
client-side protocol or programming error.)
o The parameters to the remote procedure appear to be garbage from
the server's point of view. (Again, this is usually caused by a
disagreement about the protocol between client and service.)
8.2. Authentication, Integrity, and Privacy
Provisions for authentication of caller to service and vice-versa are
provided as a part of the RPC protocol. The call message has two
authentication fields: the credential and the verifier. The reply
message has one authentication field: the response verifier. The RPC
protocol specification defines all three fields to be the following
opaque type (in the eXternal Data Representation (XDR) language
[RFC4506]):
enum auth_flavor {
AUTH_NONE = 0,
AUTH_SYS = 1,
AUTH_SHORT = 2,
AUTH_DH = 3,
RPCSEC_GSS = 6
/* and more to be defined */
};
struct opaque_auth {
auth_flavor flavor;
opaque body<400>;
};
In other words, any "opaque_auth" structure is an "auth_flavor"
enumeration followed by up to 400 bytes that are opaque to
(uninterpreted by) the RPC protocol implementation.
The interpretation and semantics of the data contained within the
authentication fields are specified by individual, independent
authentication protocol specifications.
If authentication parameters were rejected, the reply message
contains information stating why they were rejected.
As demonstrated by RPCSEC_GSS, it is possible for an "auth_flavor" to
also support integrity and privacy.
8.3. Program Number Assignment
Program numbers are given out in groups according to the following
chart:
0x00000000 Reserved
0x00000001 - 0x1fffffff To be assigned by IANA
0x20000000 - 0x3fffffff Defined by local administrator
(some blocks assigned here)
0x40000000 - 0x5fffffff Transient
0x60000000 - 0x7effffff Reserved
0x7f000000 - 0x7fffffff Assignment outstanding
0x80000000 - 0xffffffff Reserved
The first group is a range of numbers administered by IANA and should
be identical for all sites. The second range is for applications
peculiar to a particular site. This range is intended primarily for
debugging new programs. When a site develops an application that
might be of general interest, that application should be given an
assigned number in the first range. Application developers may apply
for blocks of RPC program numbers in the first range by methods
described in Appendix B. The third group is for applications that
generate program numbers dynamically. The final groups are reserved
for future use, and should not be used.
8.4. Other Uses of the RPC Protocol
The intended use of this protocol is for calling remote procedures.
Normally, each call message is matched with a reply message.
However, the protocol itself is a message-passing protocol with which
other (non-procedure-call) protocols can be implemented.
8.4.1. Batching
Batching is useful when a client wishes to send an arbitrarily large
sequence of call messages to a server. Batching typically uses
reliable byte stream protocols (like TCP) for its transport. In the
case of batching, the client never waits for a reply from the server,
and the server does not send replies to batch calls. A sequence of
batch calls is usually terminated by a legitimate remote procedure
call operation in order to flush the pipeline and get positive
acknowledgement.
8.4.2. Broadcast Remote Procedure Calls
In broadcast protocols, the client sends a broadcast call to the
network and waits for numerous replies. This requires the use of
packet-based protocols (like UDP) as its transport protocol. Servers
that support broadcast protocols usually respond only when the call
is successfully processed and are silent in the face of errors, but
this varies with the application.
The principles of broadcast RPC also apply to multicasting -- an RPC
request can be sent to a multicast address.
9. The RPC Message Protocol
This section defines the RPC message protocol in the XDR data
description language [RFC4506].
enum msg_type {
CALL = 0,
REPLY = 1
};
A reply to a call message can take on two forms: the message was
either accepted or rejected.
enum reply_stat {
MSG_ACCEPTED = 0,
MSG_DENIED = 1
};
Given that a call message was accepted, the following is the status
of an attempt to call a remote procedure.
enum accept_stat {
SUCCESS = 0, /* RPC executed successfully */
PROG_UNAVAIL = 1, /* remote hasn't exported program */
PROG_MISMATCH = 2, /* remote can't support version # */
PROC_UNAVAIL = 3, /* program can't support procedure */
GARBAGE_ARGS = 4, /* procedure can't decode params */
SYSTEM_ERR = 5 /* e.g. memory allocation failure */
};
Reasons why a call message was rejected:
enum reject_stat {
RPC_MISMATCH = 0, /* RPC version number != 2 */
AUTH_ERROR = 1 /* remote can't authenticate caller */
};
Why authentication failed:
enum auth_stat {
AUTH_OK = 0, /* success */
/*
* failed at remote end
*/
AUTH_BADCRED = 1, /* bad credential (seal broken) */
AUTH_REJECTEDCRED = 2, /* client must begin new session */
AUTH_BADVERF = 3, /* bad verifier (seal broken) */
AUTH_REJECTEDVERF = 4, /* verifier expired or replayed */
AUTH_TOOWEAK = 5, /* rejected for security reasons */
/*
* failed locally
*/
AUTH_INVALIDRESP = 6, /* bogus response verifier */
AUTH_FAILED = 7, /* reason unknown */
/*
* AUTH_KERB errors; deprecated. See [RFC2695]
*/
AUTH_KERB_GENERIC = 8, /* kerberos generic error */
AUTH_TIMEEXPIRE = 9, /* time of credential expired */
AUTH_TKT_FILE = 10, /* problem with ticket file */
AUTH_DECODE = 11, /* can't decode authenticator */
AUTH_NET_ADDR = 12, /* wrong net address in ticket */
/*
* RPCSEC_GSS GSS related errors
*/
RPCSEC_GSS_CREDPROBLEM = 13, /* no credentials for user */
RPCSEC_GSS_CTXPROBLEM = 14 /* problem with context */
};
As new authentication mechanisms are added, there may be a need for
more status codes to support them. IANA will hand out new auth_stat
numbers on a simple First Come First Served basis as defined in the
"IANA Considerations" and Appendix B.
The RPC message:
All messages start with a transaction identifier, xid, followed by a
two-armed discriminated union. The union's discriminant is a
msg_type that switches to one of the two types of the message. The
xid of a REPLY message always matches that of the initiating CALL
message. NB: The "xid" field is only used for clients matching reply
messages with call messages or for servers detecting retransmissions;
the service side cannot treat this id as any type of sequence number.
struct rpc_msg {
unsigned int xid;
union switch (msg_type mtype) {
case CALL:
call_body cbody;
case REPLY:
reply_body rbody;
} body;
};
Body of an RPC call:
In version 2 of the RPC protocol specification, rpcvers MUST be equal
to 2. The fields "prog", "vers", and "proc" specify the remote
program, its version number, and the procedure within the remote
program to be called. After these fields are two authentication
parameters: cred (authentication credential) and verf (authentication
verifier). The two authentication parameters are followed by the
parameters to the remote procedure, which are specified by the
specific program protocol.
The purpose of the authentication verifier is to validate the
authentication credential. Note that these two items are
historically separate, but are always used together as one logical
entity.
struct call_body {
unsigned int rpcvers; /* must be equal to two (2) */
unsigned int prog;
unsigned int vers;
unsigned int proc;
opaque_auth cred;
opaque_auth verf;
/* procedure-specific parameters start here */
};
Body of a reply to an RPC call:
union reply_body switch (reply_stat stat) {
case MSG_ACCEPTED:
accepted_reply areply;
case MSG_DENIED:
rejected_reply rreply;
} reply;
Reply to an RPC call that was accepted by the server:
There could be an error even though the call was accepted. The first
field is an authentication verifier that the server generates in
order to validate itself to the client. It is followed by a union
whose discriminant is an enum accept_stat. The SUCCESS arm of the
union is protocol-specific. The PROG_UNAVAIL, PROC_UNAVAIL,
GARBAGE_ARGS, and SYSTEM_ERR arms of the union are void. The
PROG_MISMATCH arm specifies the lowest and highest version numbers of
the remote program supported by the server.
struct accepted_reply {
opaque_auth verf;
union switch (accept_stat stat) {
case SUCCESS:
opaque results[0];
/*
* procedure-specific results start here
*/
case PROG_MISMATCH:
struct {
unsigned int low;
unsigned int high;
} mismatch_info;
default:
/*
* Void. Cases include PROG_UNAVAIL, PROC_UNAVAIL,
* GARBAGE_ARGS, and SYSTEM_ERR.
*/
void;
} reply_data;
};
Reply to an RPC call that was rejected by the server:
The call can be rejected for two reasons: either the server is not
running a compatible version of the RPC protocol (RPC_MISMATCH) or
the server rejects the identity of the caller (AUTH_ERROR). In case
of an RPC version mismatch, the server returns the lowest and highest
supported RPC version numbers. In case of invalid authentication,
failure status is returned.
union rejected_reply switch (reject_stat stat) {
case RPC_MISMATCH:
struct {
unsigned int low;
unsigned int high;
} mismatch_info;
case AUTH_ERROR:
auth_stat stat;
};
10. Authentication Protocols
As previously stated, authentication parameters are opaque, but
open-ended to the rest of the RPC protocol. This section defines two
standard flavors of authentication. Implementors are free to invent
new authentication types, with the same rules of flavor number
assignment as there are for program number assignment. The flavor of
a credential or verifier refers to the value of the "flavor" field in
the opaque_auth structure. Flavor numbers, like RPC program numbers,
are also administered centrally, and developers may assign new flavor
numbers by methods described in Appendix B. Credentials and
verifiers are represented as variable-length opaque data (the "body"
field in the opaque_auth structure).
In this document, two flavors of authentication are described. Of
these, Null authentication (described in the next subsection) is
mandatory -- it MUST be available in all implementations. System
authentication (AUTH_SYS) is described in Appendix A. Implementors
MAY include AUTH_SYS in their implementations to support existing
applications. See "Security Considerations" for information about
other, more secure, authentication flavors.
10.1. Null Authentication
Often, calls must be made where the client does not care about its
identity or the server does not care who the client is. In this
case, the flavor of the RPC message's credential, verifier, and reply
verifier is "AUTH_NONE". Opaque data associated with "AUTH_NONE" is
undefined. It is recommended that the length of the opaque data be
zero.
11. Record Marking Standard
When RPC messages are passed on top of a byte stream transport
protocol (like TCP), it is necessary to delimit one message from
another in order to detect and possibly recover from protocol errors.
This is called record marking (RM). One RPC message fits into one RM
record.
A record is composed of one or more record fragments. A record
fragment is a four-byte header followed by 0 to (2**31) - 1 bytes of
fragment data. The bytes encode an unsigned binary number; as with
XDR integers, the byte order is from highest to lowest. The number
encodes two values -- a boolean that indicates whether the fragment
is the last fragment of the record (bit value 1 implies the fragment
is the last fragment) and a 31-bit unsigned binary value that is the
length in bytes of the fragment's data. The boolean value is the
highest-order bit of the header; the length is the 31 low-order bits.
(Note that this record specification is NOT in XDR standard form!)
12. The RPC Language
Just as there was a need to describe the XDR data-types in a formal
language, there is also need to describe the procedures that operate
on these XDR data-types in a formal language as well. The RPC
language is an extension to the XDR language, with the addition of
"program", "procedure", and "version" declarations. The keywords
"program" and "version" are reserved in the RPC language, and
implementations of XDR compilers MAY reserve these keywords even when
provided with pure XDR, non-RPC, descriptions. The following example
is used to describe the essence of the language.
12.1. An Example Service Described in the RPC Language
Here is an example of the specification of a simple ping program.
program PING_PROG {
/*
* Latest and greatest version
*/
version PING_VERS_PINGBACK {
void
PINGPROC_NULL(void) = 0;
/*
* Ping the client, return the round-trip time
* (in microseconds). Returns -1 if the operation
* timed out.
*/
int
PINGPROC_PINGBACK(void) = 1;
} = 2;
/*
* Original version
*/
version PING_VERS_ORIG {
void
PINGPROC_NULL(void) = 0;
} = 1;
} = 1;
const PING_VERS = 2; /* latest version */
The first version described is PING_VERS_PINGBACK with two
procedures: PINGPROC_NULL and PINGPROC_PINGBACK. PINGPROC_NULL takes
no arguments and returns no results, but it is useful for computing
round-trip times from the client to the server and back again. By
convention, procedure 0 of any RPC protocol should have the same
semantics and never require any kind of authentication. The second
procedure is used for the client to have the server do a reverse ping
operation back to the client, and it returns the amount of time (in
microseconds) that the operation used. The next version,
PING_VERS_ORIG, is the original version of the protocol, and it does
not contain the PINGPROC_PINGBACK procedure. It is useful for
compatibility with old client programs, and as this program matures,
it may be dropped from the protocol entirely.
12.2. The RPC Language Specification
The RPC language is identical to the XDR language defined in RFC
4506, except for the added definition of a "program-def", described
below.
program-def:
"program" identifier "{"
version-def
version-def *
"}" "=" constant ";"
version-def:
"version" identifier "{"
procedure-def
procedure-def *
"}" "=" constant ";"
procedure-def:
proc-return identifier "(" proc-firstarg
("," type-specifier )* ")" "=" constant ";"
proc-return: "void" | type-specifier
proc-firstarg: "void" | type-specifier
12.3. Syntax Notes
o The following keywords are added and cannot be used as
identifiers: "program" and "version".
o A version name cannot occur more than once within the scope of a
program definition. Neither can a version number occur more than
once within the scope of a program definition.
o A procedure name cannot occur more than once within the scope of a
version definition. Neither can a procedure number occur more
than once within the scope of version definition.
o Program identifiers are in the same name space as constant and
type identifiers.
o Only unsigned constants can be assigned to programs, versions, and
procedures.
o Current RPC language compilers do not generally support more than
one type-specifier in procedure argument lists; the usual practice
is to wrap arguments into a structure.
13. IANA Considerations
The assignment of RPC program numbers, authentication flavor numbers,
and authentication status numbers has in the past been performed by
Sun Microsystems, Inc (Sun). This is inappropriate for an IETF
Standards Track protocol, as such work is done well by the Internet
Assigned Numbers Authority (IANA). This document proposes the
transfer of authority over RPC program numbers, authentication flavor
numbers, and authentication status numbers described here from Sun
Microsystems, Inc. to IANA and describes how IANA will maintain and
assign these numbers. Users of RPC protocols will benefit by having
an independent body responsible for these number assignments.
13.1. Numbering Requests to IANA
Appendix B of this document describes the information to be sent to
IANA to request one or more RPC numbers and the rules that apply.
IANA will store the request for documentary purposes and put the
following information into the public registry:
o The short description of purpose and use
o The program number(s) assigned
o The short identifier string(s)
13.2. Protecting Past Assignments
Sun has made assignments in both the RPC program number space and the
RPC authentication flavor number space since the original deployment
of RPC. The assignments made by Sun Microsystems are still valid,
and will be preserved. Sun has communicated all current assignments
in both number spaces to IANA and final handoff of number assignment
is complete. Current program and auth number assignments are
provided in Appendix C. Current authentication status numbers are
listed in Section 9 of this document in the "enum auth_stat"
definition.
13.3. RPC Number Assignment
Future IANA practice will deal with the following partitioning of the
32-bit number space as listed in Section 8.3. Detailed information
for the administration of the partitioned blocks in Section 8.3 is
given below.
13.3.1. To Be Assigned By IANA
The first block will be administered by IANA, with previous
assignments by Sun protected. Previous assignments were restricted
to the range decimal 100000-399999 (0x000186a0 to 0x00061a7f);
therefore, IANA will begin assignments at decimal 400000. Individual
numbers should be grated on a First Come First Served basis, and
blocks should be granted under rules related to the size of the
block.
13.3.2. Defined by Local Administrator
The "Defined by local administrator" block is available for any local
administrative domain to use, in a similar manner to IP address
ranges reserved for private use. The expected use would be through
the establishment of a local domain "authority" for assigning numbers
from this range. This authority would establish any policies or
procedures to be used within that local domain for use or assignment
of RPC numbers from the range. The local domain should be
sufficiently isolated that it would be unlikely that RPC applications
developed by other local domains could communicate with the domain.
This could result in RPC number contention, which would cause one of
the applications to fail. In the absence of a local administrator,
this block can be utilized in a "Private Use" manner per [RFC5226].
13.3.3. Transient Block
The "Transient" block can be used by any RPC application on an "as
available" basis. This range is intended for services that can
communicate a dynamically selected RPC program number to clients of
the service. Any mechanism can be used to communicate the number.
For example, either shared memory when the client and server are
located on the same system or a network message (either RPC or
otherwise) that disseminates the selected number can be used.
The transient block is not administered. An RPC service uses this
range by selecting a number in the transient range and attempting to
register that number with the local system's RPC bindery (see the
RPCBPROC_SET or PMAPPROC_SET procedures in "Binding Protocols for ONC
RPC Version 2", [RFC1833]). If successful, no other RPC service was
using that number and the RPC Bindery has assigned that number to the
requesting RPC application. The registration is valid until the RPC
Bindery terminates, which normally would only happen if the system
reboots, causing all applications, including the RPC service using
the transient number, to terminate. If the transient number
registration fails, another RPC application is using the number and
the requestor must select another number and try again. To avoid
conflicts, the recommended method is to select a number randomly from
the transient range.
13.3.4. Reserved Block
The "Reserved" blocks are available for future use. RPC applications
must not use numbers in these ranges unless their use is allowed by
future action by the IESG.
13.3.5. RPC Number Sub-Blocks
RPC numbers are usually assigned for specific RPC services. Some
applications, however, require multiple RPC numbers for a service.
The most common example is an RPC service that needs to have multiple
instances of the service active simultaneously at a specific site.
RPC does not have an "instance identifier" in the protocol, so either
a mechanism must be implemented to multiplex RPC requests amongst
various instances of the service or unique RPC numbers must be used
by each instance.
In these cases, the RPC protocol used with the various numbers may be
different or the same. The numbers may either be assigned
dynamically by the application, or as part of a site-specific
administrative decision. If possible, RPC services that dynamically
assign RPC numbers should use the "Transient" RPC number block
defined in Section 13.3.3. If not possible, RPC number sub-blocks
may be requested.
Assignment of RPC Number Sub-Blocks is controlled by the size of the
sub-block being requested. "Specification Required" and "IESG
Approval" are used as defined by Section 4.1 of [RFC5226].
Size of sub-block Assignment Method Authority
----------------- ----------------- ---------
Up to 100 numbers First Come First Served IANA
Up to 1000 numbers Specification Required IANA
More than 1000 numbers IESG Approval required IESG
Note: sub-blocks can be any size. The limits given above are
maximums, and smaller size sub-blocks are allowed.
Sub-blocks sized up to 100 numbers may be assigned by IANA on a First
Come First Served basis. The RPC Service Description included in the
range must include an indication of how the sub-block is managed. At
a minimum, the statement should indicate whether the sub-block is
used with a single RPC protocol or multiple RPC protocols, and
whether the numbers are dynamically assigned or statically (through
administrative action) assigned.
Sub-blocks of up to 1000 numbers must be documented in detail. The
documentation must describe the RPC protocol or protocols that are to
be used in the range. It must also describe how the numbers within
the sub-block are to be assigned or used.
Sub-blocks sized over 1000 numbers must be documented as described
above, and the assignment must be approved by the IESG. It is
expected that this will be rare.
In order to avoid multiple requests of large blocks of numbers, the
following rule is proposed.
Requests up to and including 100 RPC numbers are handled via the
First Come First Served assignment method. This 100 number threshold
applies to the total number of RPC numbers assigned to an individual
or entity. For example, if an individual or entity first requests,
say, 70 numbers, and then later requests 40 numbers, then the request
for the 40 numbers will be assigned via the Specification Required
method. As long as the total number of numbers assigned does not
exceed 1000, IANA is free to waive the Specification Required
assignment for incremental requests of less than 100 numbers.
If an individual or entity has under 1000 numbers and later requests
an additional set of numbers such that the individual or entity would
be granted over 1000 numbers, then the additional request will
require IESG Approval.
13.4. RPC Authentication Flavor Number Assignment
The second number space is the authentication mechanism identifier,
or "flavor", number. This number is used to distinguish between
various authentication mechanisms that can be optionally used with an
RPC message. An authentication identifier is used in the "flavor"
field of the "opaque_auth" structure.
13.4.1. Assignment Policy
Appendix B of this document describes the information to be sent to
IANA to request one or more RPC auth numbers and the rules that
apply. IANA will store the request for documentary purposes and put
the following information into the public registry:
o The short identifier string(s)
o The auth number(s) assigned
o The short description of purpose and use
13.4.2. Auth Flavors vs. Pseudo-Flavors
Recent progress in RPC security has moved away from new auth flavors
as used by AUTH_DH [DH], and has focused on using the existing
RPCSEC_GSS [RFC2203] flavor and inventing novel GSS-API (Generic
Security Services Application Programming Interface) mechanisms that
can be used with it. Even though RPCSEC_GSS is an assigned
authentication flavor, use of a new RPCSEC_GSS mechanism with the
Network File System (NFS) ([RFC1094] [RFC1813], and [RFC3530]) will
require the registration of 'pseudo-flavors' that are used to
negotiate security mechanisms in an unambiguous way, as defined by
[RFC2623]. Existing pseudo-flavors have been granted in the decimal
range 390000-390255. New pseudo-flavor requests will be granted by
IANA within this block on a First Come First Served basis.
For non-pseudo-flavor requests, IANA will begin granting RPC
authentication flavor numbers at 400000 on a First Come First Served
basis to avoid conflicts with currently granted numbers.
For authentication flavors or RPCSEC_GSS mechanisms to be used on the
Internet, it is strongly advised that an Informational or Standards
Track RFC be published describing the authentication mechanism
behaviour and parameters.
13.5. Authentication Status Number Assignment
The final number space is the authentication status or "auth_stat"
values that describe the nature of a problem found during an attempt
to authenticate or validate authentication. The complete initial
list of these values is found in Section 9 of this document, in the
"auth_stat" enum listing. It is expected that it will be rare to add
values, but that a small number of new values may be added from time
to time as new authentication flavors introduce new possibilities.
Numbers should be granted on a First Come First Served basis to avoid
conflicts with currently granted numbers.
13.5.1. Assignment Policy
Appendix B of this document describes the information to be sent to
IANA to request one or more auth_stat values and the rules that
apply. IANA will store the request for documentary purposes, and put
the following information into the public registry:
o The short identifier string(s)
o The auth_stat number(s) assigned
o The short description of purpose and use
14. Security Considerations
AUTH_SYS as described in Appendix A is known to be insecure due to
the lack of a verifier to permit the credential to be validated.
AUTH_SYS SHOULD NOT be used for services that permit clients to
modify data. AUTH_SYS MUST NOT be specified as RECOMMENDED or
REQUIRED for any Standards Track RPC service.
AUTH_DH as mentioned in Sections 8.2 and 13.4.2 is considered
obsolete and insecure; see [RFC2695]. AUTH_DH SHOULD NOT be used for
services that permit clients to modify data. AUTH_DH MUST NOT be
specified as RECOMMENDED or REQUIRED for any Standards Track RPC
service.
[RFC2203] defines a new security flavor, RPCSEC_GSS, which permits
GSS-API [RFC2743] mechanisms to be used for securing RPC. All non-
trivial RPC programs developed in the future should implement
RPCSEC_GSS-based security appropriately. [RFC2623] describes how
this was done for a widely deployed RPC program.
Standards Track RPC services MUST mandate support for RPCSEC_GSS, and
MUST mandate support for an authentication pseudo-flavor with
appropriate levels of security, depending on the need for simple
authentication, integrity (a.k.a. non-repudiation), or data privacy.
Appendix A: System Authentication
The client may wish to identify itself, for example, as it is
identified on a UNIX(tm) system. The flavor of the client credential
is "AUTH_SYS". The opaque data constituting the credential encodes
the following structure:
struct authsys_parms {
unsigned int stamp;
string machinename<255>;
unsigned int uid;
unsigned int gid;
unsigned int gids<16>;
};
The "stamp" is an arbitrary ID that the caller machine may generate.
The "machinename" is the name of the caller's machine (like
"krypton"). The "uid" is the caller's effective user ID. The "gid"
is the caller's effective group ID. "gids" are a counted array of
groups that contain the caller as a member. The verifier
accompanying the credential should have "AUTH_NONE" flavor value
(defined above). Note that this credential is only unique within a
particular domain of machine names, uids, and gids.
The flavor value of the verifier received in the reply message from
the server may be "AUTH_NONE" or "AUTH_SHORT". In the case of
"AUTH_SHORT", the bytes of the reply verifier's string encode an
opaque structure. This new opaque structure may now be passed to the
server instead of the original "AUTH_SYS" flavor credential. The
server may keep a cache that maps shorthand opaque structures (passed
back by way of an "AUTH_SHORT" style reply verifier) to the original
credentials of the caller. The caller can save network bandwidth and
server cpu cycles by using the shorthand credential.
The server may flush the shorthand opaque structure at any time. If
this happens, the remote procedure call message will be rejected due
to an authentication error. The reason for the failure will be
"AUTH_REJECTEDCRED". At this point, the client may wish to try the
original "AUTH_SYS" style of credential.
It should be noted that use of this flavor of authentication does not
guarantee any security for the users or providers of a service, in
itself. The authentication provided by this scheme can be considered
legitimate only when applications using this scheme and the network
can be secured externally, and privileged transport addresses are
used for the communicating end-points (an example of this is the use
of privileged TCP/UDP ports in UNIX systems -- note that not all
systems enforce privileged transport address mechanisms).
Appendix B: Requesting RPC-Related Numbers from IANA
RPC program numbers, authentication flavor numbers, and
authentication status numbers that must be unique across all networks
are assigned by the Internet Assigned Number Authority. To apply for
a single number or a block of numbers, electronic mail must be sent
to IANA <iana@iana.org> with the following information:
o The type of number(s) (program number or authentication flavor
number or authentication status number) sought
o How many numbers are sought
o The name of the person or company that will use the number
o An "identifier string" that associates the number with a service
o Email address of the contact person for the service that will be
using the number
o A short description of the purpose and use of the number
o If an authentication flavor number is sought, and the number will
be a 'pseudo-flavor' intended for use with RPCSEC_GSS and NFS,
mappings analogous to those in Section 4.2 of [RFC2623]
Specific numbers cannot be requested. Numbers are assigned on a
First Come First Served basis.
For all RPC authentication flavor and authentication status numbers
to be used on the Internet, it is strongly advised that an
Informational or Standards Track RFC be published describing the
authentication mechanism behaviour and parameters.
