Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and

associated changes that had to happen to make this possible as well as
bugs fixed along the way.

  Bring in required TLI library routines to support this.

  Since we don't support TLI we've essentially copied what NetBSD
  has done, adding a thin layer to emulate direct the TLI calls
  into BSD socket calls.

  This is mostly from Sun's tirpc release that was made in 1994,
  however some fixes were backported from the 1999 release (supposedly
  only made available after this porting effort was underway).

  The submitter has agreed to continue on and bring us up to the
  1999 release.

  Several key features are introduced with this update:
    Client calls are thread safe. (1999 code has server side thread
    safe)
    Updated, a more modern interface.

  Many userland updates were done to bring the code up to par with
  the recent RPC API.

  There is an update to the pthreads library, a function
  pthread_main_np() was added to emulate a function of Sun's threads
  library.

  While we're at it, bring in NetBSD's lockd, it's been far too
  long of a wait.

  New rpcbind(8) replaces portmap(8) (supporting communication over
  an authenticated Unix-domain socket, and by default only allowing
  set and unset requests over that channel). It's much more secure
  than the old portmapper.

  Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
  to support TI-RPC and to support IPV6.

  Umount(8) is also fixed to unmount pathnames longer than 80 chars,
  which are currently truncated by the Kernel statfs structure.

*
* 3. There should be no dependency on any particular thread engine.
*
* 4. The library should be able to be compiled without support for thread
* safety.
*
*
* Rationale:
*
* One approach for thread safety is to provide discrete versions of the
* library: one thread safe, the other not. The disadvantage of this is
* that libc is rather large, and two copies of a library which are 99%+
* identical is not an efficent use of resources.
*
* Another approach is to provide a single thread safe library. However,
* it should not add significant run time or code size overhead to non-
* threaded applications.
*
* Since the NetBSD C library is used in other projects, it should be
* easy to replace the mutual exclusion primitives with ones provided by
* another system. Similarly, it should also be easy to remove all
* support for thread safety completely if the target environment does
* not support threads.
*
*
* Implementation Details:
*
* The mutex primitives used by the library (mutex_t, mutex_lock, etc.)
* are macros which expand to the cooresponding primitives provided by
* the thread engine or to nothing. The latter is used so that code is
* not unreasonably cluttered with #ifdefs when all thread safe support
* is removed.
*
* The mutex macros can be directly mapped to the mutex primitives from
* pthreads, however it should be reasonably easy to wrap another mutex
* implementation so it presents a similar interface.
*
* Stub implementations of the mutex functions are provided with *weak*
* linkage. These functions simply return success. When linked with a
* thread library (i.e. -lpthread), the functions will override the
* stubs.

RPCSRC 4.0 7/11/89
$FreeBSD$
This distribution contains Sun Microsystem's implementation of the
RPC and XDR protocols and is compatible with 4.2BSD and 4.3BSD. Also
included is complete documentation, utilities, RPC service
specification files, and demonstration services in the format used by
the RPC protocol compiler (rpcgen). See WHAT'S NEW below for
details.
PLEASE READ THE DISCLAIMER FILE. DO NOT CALL THE SUN MICROSYSTEMS SUPPORT
LINE WITH QUESTIONS ON THIS RELEASE. THEY CANNOT ANSWER QUESTIONS ABOUT THIS
UNSUPPORTED SOURCE RELEASE.
NOTE ABOUT SECURE RPC:
TIRPCSRC 2.3 29 Aug 1994
This release of RPCSRC contains most of the code needed to implement
Secure RPC (see "DES Authentication" in the RPC Protocol Specification,
doc/rpc.rfc.ms). Due to legal considerations, we are unable to
distribute an implementation of DES, the Data Encryption Standard, which
Secure RPC requires. For this reason, all of the files, documentation, and
programs associated with Secure RPC have been placed into a separate
directory, secure_rpc. The RPC library contained in the main body of this
release *DOES NOT* support Secure RPC. See secure_rpc/README for more
details. (A DES library was posted in Volume 18 of comp.sources.unix.)
This distribution contains SunSoft's implementation of transport-independent
RPC (TI-RPC), External Data Representation (XDR), and various utilities and
documentation. These libraries and programs form the base of Open Network
Computing (ONC), and are derived directly from the Solaris 2.3 source.
If you wish to report bugs found in this release, send mail to:
Previous releases of RPC Source based on SunOS 4.x were ported to 4.2BSD and
used Sockets as the transport interface. These versions were
transport-specific RPC (TS-RPC).

TI-RPC is an enhanced version of TS-RPC that requires the UNIX System V
Transport Layer Interface (TLI) or an equivalent X/Open Transport Interface
(XTI). TI-RPC is on-the-wire compatible with the TS-RPC, which is supported
by almost 70 vendors on all major operating systems. TS-RPC source code
(RPCSRC 4.0) remains available from several internet sites.
This release is a native source release, that is, it is compatible for
building on Solaris 2.3. This release was built on Solaris 2.3 using SunPro
SPARCompiler 2.0.1.
Solaris 2.3 is based on System V, Release 4 (SVR4), and while this release
should be mostly compatible with other SVR4 systems, some Solaris facilities
that are assumed may not be available. In particular, this release uses the
Makefile format supported by SparcCompiler 2.0.1. Second, the Secure RPC
routines use the Solaris Name Service Switch to access public-key credential
databases. This code will need to be ported if your system does not support
the Name Service Switch. Finally, this release uses the synchronization
interfaces of UI Threads to make certain interfaces thread-safe. These
interfaces are found in libthread in Solaris 2.3 and later.
Applications linked with this release's librpc must link with the United
States domestic version of libcrypt in order to resolve the cbc_crypt() and
ecb_crypt() functions. These routines are used with Secure RPC however all
RPC programs that link with this release's librpc will need to link with the
domestic libcrypt. Note that the Solaris 2.3 Encryption Kit is only available
within the United States. (PLEASE NOTE: The RPC implementation found in
Solaris 2.3's libnsl does *not* have this requirement; linking with libcrypt
is only a requirement for the TIRPCSRC 2.3 version of librpc.)
DOCUMENTATION NOTE
The documentation found in the doc directory are derived from the Solaris 2.3
Network Interfaces Programming Guide. A small number of compile examples are
given, and these use libnsl to link in the RPC library. This release builds
the RPC library as librpc. To use this release's librpc, use the link command
"-lrpc -lnsl -lcrypt". This links the application with TIRPCSRC 2.3's librpc
for RPC routines, Solaris's libnsl for other networking functions, and
libcrypt for the cbc_crypt() and ecb_crypt functions.
WHY IS THIS RELEASE BEING DONE?
This release is being distributed to make the Sun implementation of the ONC
technologies available for reference and porting to non-Solaris platforms.
The current release is a native source distribution, and provides services
that are already available on Solaris 2.3 (such as the RPC headers, the RPC
library in libnsl, rpcbind, rpcinfo, etc.). It is not our intention to
replace these services. See the DISCLAIMER for further information about the
legal status of this release.
WHAT'S NEW IN THIS RELEASE: TIRPCSRC 2.3
The previous release was TIRPCSRC 2.0.
1. This release is based on Solaris 2.3. The previous release was
based on Solaris 2.0. This release contains a siginificant number of
bug fixes and other enhancements over TIRPCSRC 2.0.
2. The RPC library is thread safe for all client-side interfaces
(clnt_create, clnt_call, etc.). The server-side interfaces
(svc_create, svc_run, etc.) are not thread safe in this release. The
server-side interfaces will be made thread safe in the next release of
TIRPCSRC. Please see the manual pages for details about which
interfaces are thread safe.
3. As part of the work to make the RPC library thread-safe, rpcgen has
been enhanced to generate thread-safe RPC stubs (the -M option). Note
that this modifies the call-signature for the stub functions; the
procedure calling the RPC stub must now pass to the stub a pointer to
an allocated structure where results will be placed by the stub. See
the rpcgen manual page and the rpcgen Programming Guide for details.
4. The Remote Asynchronous Calls (RAC) library is now included. RAC was
first introduced in TIRPCSRC 1.0, and was bundled with librpc. It is
now a separate library. The asynchronous call model that RAC provides
can be achieved by using threads for making client-side RPC calls.
The ONC Technology group recommends using threads (where possible) to
achieve asynchrony rather than RAC. See the rpc_rac(3n) manual page
for details.

BUILD INSTRUCTIONS
Makefiles can be found in all directories except for man. The
Makefile in the top directory will cause these others to be invoked
(except for in the doc, man and demo directories), in turn building the
entire release.
Prior to building the release, you must define the SRC environment variable
to be the path to the top-level Makefile. For example, if /usr/src/tirpcsrc
is where to top-level Makefile is located, execute this command prior to
building the release:
WARNING! THE DEFAULT INSTALLATION PROCEDURES WILL INSTALL FILES
IN /usr/include, /usr/lib, /usr/bin and /etc.
setenv SRC /usr/src/tirpcsrc (csh)
or
SRC=/usr/src/tirpcsrc; export SRC (sh)
The master RPC include file, rpc/rpc.h, is used by all programs and
routines that use RPC. It includes other RPC and system include files
needed by the RPC system. PLEASE NOTE: If your system has NFS, it
may have been based on Sun's NFS Source. The include files installed
by this package may duplicate include files you will find on your NFS
system. The RPCSRC 4.0 include files are upwardly compatible to all
NFS Source include files as of the date of this distribution (not
including any new definitions or declarations added by your system
vendor). HOWEVER: Please read the comments towards the end of
rpc/rpc.h regarding rpc/netdb.h. You may need to uncomment the
inclusion of that file if the structures it defines are already
defined by your system's include files.
The sources in the lib directory depend on header files installed from head
and uts/common/rpc, and the programs in the cmd directory depend on libraries
from lib. Therefore, you should do a "make install" to build the release.
After making any compiler fixes that are needed (see below), at
the top directory, type:
The top-level Makefile builds the release. The "ROOT" macro defines where the
headers and libraries are installed. The default for ROOT is "/proto". You
may change this by either modifiying Makefile.master, or issuing the build
command with a new definition for ROOT:
make install
make install ROOT=/opt/onc
For all installations, the Makefile macro DESTDIR is prepended to the
installation path. It is defined to be null in the Makefiles, so
installations are relative to root. (You will probably need root
privileges for installing the files under the default path.) To
install the files under some other tree (e.g., /usr/local), use the
command:
You will of course need write privileges for the destination directory.
The headers, libraries and executables will be built and installed under the
ROOT.
make install DESTDIR=/usr/local
This will place the include files in /usr/local/usr/include, the RPC
library in /usr/local/usr/lib, rpcgen in /usr/local/usr/bin, and the
utilities in /usr/local/etc. You'll have to edit the Makefiles or
install the files by hand if you want to do anything other than this
kind of relocation of the installation tree.
The RPC library will be built and installed first. By default it is
installed in /usr/lib as "librpclib.a". The directory
/usr/include/rpc will also be created, and several header files will
be installed there. ALL RPC SERVICES INCLUDE THESE HEADER FILES.
The programs in etc/ link in routines from librpclib.a. If you change
where it is installed, be sure to edit etc/'s Makefile to reflect this.
These programs are installed in /etc. PORTMAP MUST BE RUNNING ON
YOUR SYSTEM BEFORE YOU START ANY OTHER RPC SERVICE.
rpcgen is installed in /usr/bin. This program is required to build
the demonstration services in demo and the rstat client and server in
rpcsvc/.
The rpcsvc/ directory will install its files in the directory
/usr/include/rpcsvc. The Remote Status service (rstat_svc) will be
compiled and installed in /etc. If you wish to make this service
available, you should either start this service when needed or have
it started at boot time by invoking it in your /etc/rc.local script.
(Be sure that portmap is started first!) Sun has modified its
version of inetd to automatically start RPC services. (Use "make
LIB=" when building rstat on a Sun Workstation.) The Remote Status
client (rstat) will be installed in /usr/bin. This program queries
the rstat_svc on a remote host and prints a system status summary
similar to the one printed by "uptime".
The documentation is not built during the "make install" command.
Typing "make" in the doc directory will cause all of the manuals to
be formatted using nroff into a single file. We have had a report
that certain "troff" equivalents have trouble processing the full
manual. If you have trouble, try building the manuals individually
(see the Makefile).
The demonstration services in the demo directory are not built by the
top-level "make install" command. To build these, cd to the demo
directory and enter "make". The three services will be built.
top-level "make install" command. To build these, cd to the cmd/demo
directory and enter "make". The four services will be built.
RPCGEN MUST BE INSTALLED in a path that make can find. To run the
services, start the portmap program as root and invoke the service
services, rpcbind must be running, then invoke the service
(you probably will want to put it in the background). rpcinfo can be
used to check that the service succeeded in getting registered with
portmap, and to ping the service (see rpcinfo's man page). You can
rpcbind, and to ping the service (see rpcinfo's man page). You can
then use the corresponding client program to exercise the service.
To build these services on a Sun workstation, you must prevent the
Makefile from trying to link the RPC library (as these routines are
already a part of Sun's libc). Use: "make LIB=".
BUGFIX FOR 4.3BSD COMPILER
The use of a 'void *' declaration for one of the arguments in
the reply_proc() procedure in etc/rpcinfo.c will trigger a bug
in the 4.3BSD compiler. The bug is fixed by the following change to
the compiler file mip/manifest.h:
BUILDING ONC APPLICATIONS
*** manifest.h.r1.1 Thu Apr 30 13:52:25 1987
--- manifest.h.r1.2 Mon Nov 23 18:58:17 1987
***************
*** 21,27 ****
/*
* Bogus type values
*/
! #define TNULL PTR /* pointer to UNDEF */
#define TVOID FTN /* function returning UNDEF (for void) */
/*
--- 21,27 ----
/*
* Bogus type values
*/
! #define TNULL INCREF(MOETY) /* pointer to MOETY -- impossible type */
#define TVOID FTN /* function returning UNDEF (for void) */
/*
See the Makefiles in the demonstration services for examples of building
ONC applications with this release. The $(ROOT)/usr/include directory
must be included in the compiler header file search path (-I), and the
$(ROOT)/usr/lib directory must be included in the linker library file search
path (-L). Also, to run executables built dynamically, the shared library
search path (LD_LIBRARY_PATH) must also include $(ROOT)/usr/lib. In addition
to linking in this release's librpc (via -lrpc), you must also link with
Solaris's libnsl (-lnsl) and the US domestic version of libcrypt (-lcrypt).
If you cannot fix your compiler, change the declaration in reply_proc()
from 'void *' to 'char *'.
BUGFIX FOR 4.2BSD COMPILER
Unpatched 4.2BSD compilers complain about valid C. You can make old
compilers happy by changing some voids to ints. However, the fix to
the 4.2 VAX compiler is as follows (to mip/trees.c):
*** trees.c.r1.1 Mon May 11 13:47:58 1987

WHAT'S NEW IN THIS RELEASE: RPCSRC 4.0
The previous release was RPCSRC 3.9. As with all previous releases,
this release is based directly on files from Sun Microsystem's
implementation.
Upgrade from RPCSRC 3.9
1) RPCSRC 4.0 upgrades RPCSRC 3.9. Improvements from SunOS 4.0 have
been integrated into this release.
Secure RPC (in the secure_rpc/ directory)
2) DES Authentication routines and programs are provided.
3) A new manual, "Secure NFS" is provided, which describes Secure RPC
and Secure NFS.
4) Skeleton routines and manual pages are provided which describe the
DES encryption procedures required by Secure RPC. HOWEVER, NO DES
ROUTINE IS PROVIDED.
New Functionality
5) rpcinfo can now be used to de-register services from the portmapper
which may have terminated abnormally.
6) A new client, rstat, is provided which queries the rstat_svc and
prints a status line similar to the one displayed by "uptime".

Note that
.Fa sin->sin_family
must be initialized to the address family of the socket, passed by

If

If

an anonymous port will be allocated (as above).
However, there is no way for

* deadlock (netlock) the client and the server....

* Clients should NOT casually batch calls that in fact return results; that is,
* the server side should be aware that a call is batched and not produce any

* deadlock (netlock) the client and the server....

.Fn getnetconfig "void *handlep"
.Ft "void *"
.Fn setnetconfig "void"
.Ft int
.Fn endnetconfig "void *handlep"

.Fn nc_perror "const char *msg"
.Ft "char *"
.Fn nc_sperror "void"
.Sh DESCRIPTION
The library routines described on this page
provide the application access to
the system network configuration database,
.Pa /etc/netconfig .
.Fn getnetconfig
returns a pointer to the
current entry in the
netconfig
database, formatted as a
.Ft "struct netconfig" .
Successive calls will return successive netconfig
entries in the netconfig database.
.Fn getnetconfig
can be used to search the entire netconfig
file.
.Fn getnetconfig
returns
.Dv NULL
at the end of the file.
.Fa handlep
is the handle obtained through
.Fn setnetconfig .
.Pp
A call to
.Fn setnetconfig
has the effect of
.Dq binding
to or
.Dq rewinding
the netconfig database.
.Fn setnetconfig
must be called before the first call to
.Fn getnetconfig
and may be called at any other time.
.Fn setnetconfig
need not be called before a call to
.Fn getnetconfigent .
.Fn setnetconfig
returns a unique handle to be used by
.Fn getnetconfig .
.Pp
.Fn endnetconfig
should be called when processing is complete to release resources for reuse.
.Fa handlep
is the handle obtained through
.Fn setnetconfig .
Programmers should be aware, however, that the last call to
.Fn endnetconfig
frees all memory allocated by
.Fn getnetconfig
for the
.Ft "struct netconfig"
data structure.
.Fn endnetconfig
may not be called before
.Fn setnetconfig .
.Pp
.Fn getnetconfigent
returns a pointer
to the netconfig structure corresponding
to
.Fa netid .
It returns
.Dv NULL
if
.Fa netid
is invalid
(that is, does not name an entry in the netconfig database).
.Pp
.Fn freenetconfigent
frees the netconfig structure pointed to by
.Fa netconfigp
(previously returned by
.Fn getnetconfigent ) .
.Pp
.Fn nc_perror
prints a message to the standard error indicating why any of the
above routines failed.
The message is prepended with the string
.Fa msg
and a colon.
A newline character is appended at the end of the message.
.Pp
.Fn nc_sperror
is similar to
.Fn nc_perror
but instead of sending the message
to the standard error, will return a pointer to a string that
contains the error message.
.Pp
.Fn nc_perror
and
.Fn nc_sperror
can also be used with the
.Ev NETPATH
access routines defined in
.Xr getnetpath 3 .
.Sh RETURN VALUES
.Fn setnetconfig
returns a unique handle to be used by
.Fn getnetconfig .
In the case of an error,
.Fn setnetconfig
returns
.Dv NULL
and
.Fn nc_perror
or
.Fn nc_sperror
can be used to print the reason for failure.
.Pp
.Fn getnetconfig
returns a pointer to the current entry in the netconfig
database, formatted as a
.Ft "struct netconfig" .
.Fn getnetconfig
returns
.Dv NULL
at the end of the file, or upon failure.
.Pp
.Fn endnetconfig
returns 0 on success and \-1 on failure
(for example, if
.Fn setnetconfig
was not called previously).
.Pp
On success,
.Fn getnetconfigent
returns a pointer to the
.Ft "struct netconfig"
structure corresponding to
.Fa netid ;
otherwise it returns
.Dv NULL .
.Pp
.Fn nc_sperror
returns a pointer to a buffer which contains the error message string.
This buffer is overwritten on each call.
In multithreaded applications, this buffer is
implemented as thread-specific data.

.Nm getnetpath ,
.Nm setnetpath ,

.Nd get
.Pa /etc/netconfig
entry corresponding to
.Ev NETPATH
component
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.Fd #include <netconfig.h>
.Ft "struct netconfig *"
.Fn getnetpath "void *handlep"
.Ft "void *"
.Fn setnetpath "void"
.Ft int
.Fn endnetpath "void *handlep"
.Sh DESCRIPTION
The routines described in this page provide the application access to the system
network configuration database,
.Pa /etc/netconfig ,
as it is
.Dq filtered
by the
.Ev NETPATH
environment variable (see
.Xr environ 5 ) .
See
.Xr getnetconfig 3
for other routines that also access the
network configuration database directly.
The
.Ev NETPATH
variable is a list of colon-separated network identifiers.
.Pp
.Fn getnetpath
returns a pointer to the
netconfig database entry corresponding to the first valid
.Ev NETPATH
component.
The netconfig entry is formatted as a
.Ft "struct netconfig" .
On each subsequent call,
.Fn getnetpath
returns a pointer to the netconfig entry that corresponds to the next
valid
.Ev NETPATH
component.
.Fn getnetpath
can thus be used to search the netconfig database for all networks
included in the
.Ev NETPATH
variable.
When
.Ev NETPATH
has been exhausted,
.Fn getnetpath
returns
.Dv NULL .
.Pp
A call to
.Fn setnetpath
.Dq binds
to or
.Dq rewinds
.Ev NETPATH .
.Fn setnetpath
must be called before the first call to
.Fn getnetpath
and may be called at any other time.
It returns a handle that is used by
.Fn getnetpath .
.Pp
.Fn getnetpath
silently ignores invalid
.Ev NETPATH
components.
A
.Ev NETPATH
component is invalid if there is no corresponding
entry in the netconfig database.
.Pp
If the
.Ev NETPATH
variable is unset,
.Fn getnetpath
behaves as if
.Ev NETPATH
were set to the sequence of
.Dq default
or
.Dq visible
networks in the netconfig database, in the
order in which they are listed.
.\"This proviso holds also for this
.\"whole manpage.
.Pp
.Fn endnetpath
may be called to
.Dq unbind
from
.Ev NETPATH
when processing is complete, releasing resources for reuse.
Programmers should be aware, however, that
.Fn endnetpath
frees all memory allocated by
.Fn getnetpath
for the struct netconfig data structure.
.Sh RETURN VALUES
.Fn setnetpath
returns a handle that is used by
.Fn getnetpath .
In case of an error,
.Fn setnetpath
returns
.Dv NULL .
.Pp
.Fn endnetpath
returns 0 on success and \-1 on failure
(for example, if
.Fn setnetpath
was not called previously).
.Fn nc_perror
or
.Fn nc_sperror
can be used to print out the reason for failure.
See
.Xr getnetconfig 3 .
.Pp
When first called,
.Fn getnetpath
returns a pointer to the netconfig database entry corresponding to the first
valid
.Ev NETPATH
component.
When
.Ev NETPATH
has been exhausted,
.Fn getnetpath
returns
.Dv NULL .

.Sh NAME
.Nm netconfig
.Nd network configuration data base
.Sh SYNOPSIS
.Pa /etc/netconfig
.Sh DESCRIPTION
The
.Nm
file defines a list of
.Dq transport names ,
describing their semantics and protocol.
In
.Fx ,
this file is only used by the RPC library code.
.Pp
Entries have the following format:
.Pp
.Ar network_id semantics flags family protoname device libraries
.Pp
Entries consist of the following fields:
.Bl -tag -width network_id
.It Ar network_id
The name of the transport described.
.It Ar semantics
Describes the semantics of the transport.
This can be one of:
.Bl -tag -width tpi_cots_ord -offset indent
.It Sy tpi_clts
Connectionless transport.
.It Sy tpi_cots
Connection-oriented transport
.It Sy tpi_cots_ord
Connection-oriented, ordered transport.
.It Sy tpi_raw
A raw connection.
.El
.It Ar flags
This field is either blank (specified by
.Dq Li - ) ,
or contains a
.Dq Li v ,
meaning visible to the
.Xr getnetconfig 3
function.
.It Ar family
The protocol family of the transport.
This is currently one of:
.Bl -tag -width loopback -offset indent
.It Sy inet6
The IPv6
.Pq Dv PF_INET6
family of protocols.
.It Sy inet
The IPv4
.Pq Dv PF_INET
family of protocols.
.It Sy loopback
The
.Dv PF_LOCAL
protocol family.
.El
.It Ar protoname
The name of the protocol used for this transport.
Can currently be either
.Sy udp ,
.Sy tcp
or empty.
.It Ar device
This field is always empty in
.Fx .
.It Ar libraries
This field is always empty in
.Fx .
.El
.Pp
The order of entries in this file will determine which transport will
be preferred by the RPC library code, given a match on a specified
network type.
For example, if a sample network config file would look like this:
.Bd -literal -offset indent
udp6 tpi_clts v inet6 udp - -
tcp6 tpi_cots_ord v inet6 tcp - -
udp tpi_clts v inet udp - -
tcp tpi_cots_ord v inet tcp - -
rawip tpi_raw - inet - - -
local tpi_cots_ord - loopback - - -
.Ed
.Pp
then using the network type
.Sy udp
in calls to the RPC library function (see
.Xr rpc 3 )
will make the code first try
.Sy udp6 ,
and then
.Sy udp .
.Pp
.Xr getnetconfig 3
and associated functions will parse this file and return structures of
the following format:
.Bd -literal
struct netconfig {
char *nc_netid; /* Network ID */
unsigned long nc_semantics; /* Semantics (see below) */
unsigned long nc_flag; /* Flags (see below) */
char *nc_protofmly; /* Protocol family */
char *nc_proto; /* Protocol name */
char *nc_device; /* Network device pathname (unused) */
unsigned long nc_nlookups; /* Number of lookup libs (unused) */
char **nc_lookups; /* Names of the libraries (unused) */

These routines are part of the
RPC library that allows C language programs to make procedure
calls on other machines across the network,
with desired authentication.
.Pp
These routines are normally called after creating the
.Vt CLIENT
handle.
The
.Va cl_auth
field of the
.Vt CLIENT
structure should be initialized by the
.Vt AUTH
structure returned by some of the following routines.
The client's authentication information
is passed to the server when the
RPC
call is made.
.Pp
Only the
.Dv NULL
and the
.Dv SYS
style of authentication is discussed here.
.Sh Routines
.Bl -tag -width authsys_create_default()
.It Fn auth_destroy
A function macro that destroys the authentication
information associated with
.Fa auth .
Destruction usually involves deallocation
of private data structures.
The use of
.Fn auth
is undefined after calling
.Fn auth_destroy .
.It Fn authnone_create
Create and return an RPC
authentication handle that passes nonusable
authentication information with each remote procedure call.
This is the default authentication used by RPC.
.It Fn authsys_create
Create and return an RPC authentication handle that contains
.Dv AUTH_SYS
authentication information.
The parameter
.Fa host
is the name of the machine on which the information was
created;
.Fa uid
is the user's user ID;
.Fa gid
is the user's current group ID;
.Fa len
and
.Fa aup_gids
refer to a counted array of groups to which the user belongs.
.It Fn authsys_create_default
Call
.Fn authsys_create
with the appropriate parameters.

.Sh DESCRIPTION
RPC library routines allow C language programs to make procedure
calls on other machines across the network.
First, the client calls a procedure to send a request to the server.
Upon receipt of the request, the server calls a dispatch routine
to perform the requested service, and then sends back a reply.
.Pp
The
.Fn clnt_call ,
.Fn rpc_call ,
and
.Fn rpc_broadcast
routines handle the client side of the procedure call.
The remaining routines deal with error handling in the case of errors.
.Pp
Some of the routines take a
.Vt CLIENT
handle as one of the parameters.
A
.Vt CLIENT
handle can be created by an RPC creation routine such as
.Fn clnt_create
(see
.Xr rpc_clnt_create 3 ) .
.Pp
These routines are safe for use in multithreaded applications.
.Vt CLIENT
handles can be shared between threads, however in this implementation
requests by different threads are serialized (that is, the first request will
receive its results before the second request is sent).
.Sh Routines
See
.Xr rpc 3
for the definition of the
.Vt CLIENT
data structure.
.Bl -tag -width XXXXX
.It Fn clnt_call
A function macro that calls the remote procedure
.Fa procnum
associated with the client handle,
.Fa clnt ,
which is obtained with an RPC
client creation routine such as
.Fn clnt_create
(see
.Xr rpc_clnt_create 3 ) .
The parameter
.Fa inproc
is the XDR function used to encode the procedure's parameters, and
.Fa outproc
is the XDR function used to decode the procedure's results;
.Fa in
is the address of the procedure's argument(s), and
.Fa out
is the address of where to place the result(s).
.Fa tout
is the time allowed for results to be returned, which is overridden by
a time-out set explicitly through
.Fn clnt_control ,
see
.Xr rpc_clnt_create 3 .
If the remote call succeeds, the status returned is
.Dv RPC_SUCCESS ,
otherwise an appropriate status is returned.
.It Fn clnt_freeres
A function macro that frees any data allocated by the
RPC/XDR system when it decoded the results of an RPC call.
The parameter
.Fa out
is the address of the results, and
.Fa outproc
is the XDR routine describing the results.
This routine returns 1 if the results were successfully freed,
and 0 otherwise.
.It Fn clnt_geterr
A function macro that copies the error structure out of the client
handle to the structure at address
.Fa errp .
.It Fn clnt_perrno
Print a message to standard error corresponding
to the condition indicated by
.Fa stat .
A newline is appended.
Normally used after a procedure call fails for a routine
for which a client handle is not needed, for instance
.Fn rpc_call .
.It Fn clnt_perror
Print a message to the standard error indicating why an
RPC call failed;
.Fa clnt
is the handle used to do the call.
The message is prepended with string
.Fa s
and a colon.
A newline is appended.
Normally used after a remote procedure call fails
for a routine which requires a client handle,
for instance
.Fn clnt_call .
.It Fn clnt_sperrno
Take the same arguments as
.Fn clnt_perrno ,
but instead of sending a message to the standard error
indicating why an RPC
call failed, return a pointer to a string which contains the message.
.Fn clnt_sperrno
is normally used instead of
.Fn clnt_perrno
when the program does not have a standard error (as a program
running as a server quite likely does not), or if the programmer
does not want the message to be output with
.Fn printf
(see
.Xr printf 3 ) ,
or if a message format different than that supported by
.Fn clnt_perrno
is to be used.
Note:
unlike
.Fn clnt_sperror
and
.Fn clnt_spcreaterror
(see
.Xr rpc_clnt_create 3 ) ,
.Fn clnt_sperrno
does not return pointer to static data so the
result will not get overwritten on each call.
.It Fn clnt_sperror
Like
.Fn clnt_perror ,
except that (like
.Fn clnt_sperrno )
it returns a string instead of printing to standard error.
However,
.Fn clnt_sperror
does not append a newline at the end of the message.
Warning:
returns pointer to a buffer that is overwritten
on each call.
.It Fn rpc_broadcast
Like
.Fn rpc_call ,
except the call message is broadcast to
all the connectionless transports specified by
.Fa nettype .
If
.Fa nettype
is
.Dv NULL ,
it defaults to
.Qq netpath .
Each time it receives a response,
this routine calls
.Fn eachresult ,
whose form is:
.Ft bool_t
.Fn eachresult "caddr_t out" "const struct netbuf * addr" "const struct netconfig * netconf"
where
.Fa out
is the same as
.Fa out
passed to
.Fn rpc_broadcast ,
except that the remote procedure's output is decoded there;
.Fa addr
points to the address of the machine that sent the results, and
.Fa netconf
is the netconfig structure of the transport on which the remote
server responded.
If
.Fn eachresult
returns 0,
.Fn rpc_broadcast
waits for more replies;
otherwise it returns with appropriate status.
Warning:
broadcast file descriptors are limited in size to the
maximum transfer size of that transport.
For Ethernet, this value is 1500 bytes.
.Fn rpc_broadcast
uses
.Dv AUTH_SYS
credentials by default (see
.Xr rpc_clnt_auth 3 ) .
.It Fn rpc_broadcast_exp
Like
.Fn rpc_broadcast ,
except that the initial timeout,
.Fa inittime
and the maximum timeout,
.Fa waittime
are specified in milliseconds.
.Fa inittime
is the initial time that
.Fn rpc_broadcast_exp
waits before resending the request.
After the first resend, the re-transmission interval
increases exponentially until it exceeds
.Fa waittime .
.It Fn rpc_call
Call the remote procedure associated with
.Fa prognum ,
.Fa versnum ,
and
.Fa procnum
on the machine,
.Fa host .
The parameter
.Fa inproc
is used to encode the procedure's parameters, and
.Fa outproc
is used to decode the procedure's results;
.Fa in
is the address of the procedure's argument(s), and
.Fa out
is the address of where to place the result(s).
.Fa nettype
can be any of the values listed on
.Xr rpc 3 .
This routine returns
.Dv RPC_SUCCESS
if it succeeds,
or an appropriate status is returned.
Use the
.Fn clnt_perrno
routine to translate failure status into error messages.
Warning:
.Fn rpc_call
uses the first available transport belonging
to the class
.Fa nettype ,
on which it can create a connection.
You do not have control of timeouts or authentication
using this routine.

.Sh DESCRIPTION
RPC library routines allow C language programs to make procedure
calls on other machines across the network.
First a
.Vt CLIENT
handle is created and then the client calls a procedure to send a
request to the server.
On receipt of the request, the server calls a dispatch routine
to perform the requested service, and then sends a reply.
.Sh Routines
.Bl -tag -width YYYYYYY
.It Fn clnt_control
A function macro to change or retrieve various information
about a client object.
.Fa req
indicates the type of operation, and
.Fa info
is a pointer to the information.
For both connectionless and connection-oriented transports,
the supported values of
.Fa req
and their argument types and what they do are:
.Bl -column "CLSET_FD_NCLOSE" "struct timeval *" "set total timeout"
.It Dv CLSET_TIMEOUT Ta "struct timeval *" Ta "set total timeout"
.It Dv CLGET_TIMEOUT Ta "struct timeval *" Ta "get total timeout"
.El
.Pp
Note:
if you set the timeout using
.Fn clnt_control ,
the timeout argument passed by
.Fn clnt_call
is ignored in all subsequent calls.
.Pp
Note:
If you set the timeout value to 0,
.Fn clnt_control
immediately returns an error
.Pq Dv RPC_TIMEDOUT .
Set the timeout parameter to 0 for batching calls.
.Bl -column CLSET_FD_NCLOSE "struct timeval *" "do not close fd on destroy"
.It Dv CLGET_SVC_ADDR Ta "struct netbuf *" Ta "get servers address"
.It Dv CLGET_FD Ta "int *" Ta "get fd from handle"
.It Dv CLSET_FD_CLOSE Ta "void" Ta "close fd on destroy"
.It Dv CLSET_FD_NCLOSE Ta void Ta "don't close fd on destroy"
.It Dv CLGET_VERS Ta "unsigned long *" Ta "get RPC program version"
.It Dv CLSET_VERS Ta "unsigned long *" Ta "set RPC program version"
.It Dv CLGET_XID Ta "unsigned long *" Ta "get XID of previous call"
.It Dv CLSET_XID Ta "unsigned long *" Ta "set XID of next call"
.El
.Pp
The following operations are valid for connectionless transports only:
.Bl -column CLSET_RETRY_TIMEOUT "struct timeval *" "set total timeout"
.It Dv CLSET_RETRY_TIMEOUT Ta "struct timeval *" Ta "set the retry timeout"
.It Dv CLGET_RETRY_TIMEOUT Ta "struct timeval *" Ta "get the retry timeout"
.El
.Pp
The retry timeout is the time that RPC
waits for the server to reply before retransmitting the request.
.Fn clnt_control
returns
.Dv TRUE
on success and
.Dv FALSE
on failure.
.It Fn clnt_create
Generic client creation routine for program
.Fa prognum
and version
.Fa versnum .
.Fa host
identifies the name of the remote host where the server
is located.
.Fa nettype
indicates the class of transport protocol to use.
The transports are tried in left to right order in
.Ev NETPATH
environment variable or in top to bottom order in
the netconfig database.
.Fn clnt_create
tries all the transports of the
.Fa nettype
class available from the
.Ev NETPATH
environment variable and the netconfig database,
and chooses the first successful one.
A default timeout is set and can be modified using
.Fn clnt_control .
This routine returns
.Dv NULL
if it fails.
The
.Fn clnt_pcreateerror
routine can be used to print the reason for failure.
.Pp
Note:
.Fn clnt_create
returns a valid client handle even
if the particular version number supplied to
.Fn clnt_create
is not registered with the
.Xr rpcbind 8
service.
This mismatch will be discovered by a
.Fn clnt_call
later (see
.Xr rpc_clnt_calls 3 ) .
.It Fn clnt_create_vers
Generic client creation routine which is similar to
.Fn clnt_create
but which also checks for the
version availability.
.Fa host
identifies the name of the remote host where the server
is located.
.Fa nettype
indicates the class transport protocols to be used.
If the routine is successful it returns a client handle created for
the highest version between
.Fa vers_low
and
.Fa vers_high
that is supported by the server.
.Fa vers_outp
is set to this value.
That is, after a successful return
.Fa vers_low
<=
.Fa *vers_outp
<=
.Fa vers_high .
If no version between
.Fa vers_low
and
.Fa vers_high
is supported by the server then the routine fails and returns
.Dv NULL .
A default timeout is set and can be modified using
.Fn clnt_control .
This routine returns
.Dv NULL
if it fails.
The
.Fn clnt_pcreateerror
routine can be used to print the reason for failure.
Note:
.Fn clnt_create
returns a valid client handle even
if the particular version number supplied to
.Fn clnt_create
is not registered with the
.Xr rpcbind 8
service.
This mismatch will be discovered by a
.Fn clnt_call
later (see
.Xr rpc_clnt_calls 3 ) .
However,
.Fn clnt_create_vers
does this for you and returns a valid handle
only if a version within
the range supplied is supported by the server.
.It Fn clnt_destroy
A function macro that destroys the client's RPC handle.
Destruction usually involves deallocation
of private data structures, including
.Fa clnt
itself.
Use of
.Fa clnt
is undefined after calling
.Fn clnt_destroy .
If the RPC library opened the associated file descriptor, or
.Dv CLSET_FD_CLOSE
was set using
.Fn clnt_control ,
the file descriptor will be closed.
The caller should call
.Fn auth_destroy "clnt->cl_auth"
(before calling
.Fn clnt_destroy )
to destroy the associated
.Vt AUTH
structure (see
.Xr rpc_clnt_auth 3 ) .
.It Fn clnt_dg_create
This routine creates an RPC client for the remote program
.Fa prognum
and version
.Fa versnum ;
the client uses a connectionless transport.
The remote program is located at address
.Fa svcaddr .
The parameter
.Fa fildes
is an open and bound file descriptor.
This routine will resend the call message in intervals of
15 seconds until a response is received or until the
call times out.
The total time for the call to time out is specified by
.Fn clnt_call
(see
.Fn clnt_call
in
.Xr rpc_clnt_calls 3 ) .
The retry time out and the total time out periods can
be changed using
.Fn clnt_control .
The user may set the size of the send and receive
buffers with the parameters
.Fa sendsz
and
.Fa recvsz ;
values of 0 choose suitable defaults.
This routine returns
.Dv NULL
if it fails.
.It Fn clnt_pcreateerror
Print a message to standard error indicating
why a client RPC handle could not be created.
The message is prepended with the string
.Fa s
and a colon, and appended with a newline.
.It Fn clnt_spcreateerror
Like
.Fn clnt_pcreateerror ,
except that it returns a string
instead of printing to the standard error.
A newline is not appended to the message in this case.
Warning:
returns a pointer to a buffer that is overwritten
on each call.
.It Fn clnt_raw_create
This routine creates an RPC
client handle for the remote program
.Fa prognum
and version
.Fa versnum .
The transport used to pass messages to the service is
a buffer within the process's address space,
so the corresponding RPC
server should live in the same address space;
(see
.Fn svc_raw_create
in
.Xr rpc_svc_create 3 ) .
This allows simulation of RPC and measurement of
RPC overheads, such as round trip times,
without any kernel or networking interference.
This routine returns
.Dv NULL
if it fails.
.Fn clnt_raw_create
should be called after
.Fn svc_raw_create .
.It Fn clnt_tli_create
This routine creates an RPC
client handle for the remote program
.Fa prognum
and version
.Fa versnum .
The remote program is located at address
.Fa svcaddr .
If
.Fa svcaddr
is
.Dv NULL
and it is connection-oriented, it is assumed that the file descriptor
is connected.
For connectionless transports, if
.Fa svcaddr
is
.Dv NULL ,
.Dv RPC_UNKNOWNADDR
error is set.
.Fa fildes
is a file descriptor which may be open, bound and connected.
If it is
.Dv RPC_ANYFD ,
it opens a file descriptor on the transport specified by
.Fa netconf .
If
.Fa fildes
is
.Dv RPC_ANYFD
and
.Fa netconf
is
.Dv NULL ,
a
.Dv RPC_UNKNOWNPROTO
error is set.
If
.Fa fildes
is unbound, then it will attempt to bind the descriptor.
The user may specify the size of the buffers with the parameters
.Fa sendsz
and
.Fa recvsz ;
values of 0 choose suitable defaults.
Depending upon the type of the transport (connection-oriented
or connectionless),
.Fn clnt_tli_create
calls appropriate client creation routines.
This routine returns
.Dv NULL
if it fails.
The
.Fn clnt_pcreateerror
routine can be used to print the reason for failure.
The remote rpcbind
service (see
.Xr rpcbind 8 )
is not consulted for the address of the remote
service.
.It Fn clnt_tp_create
Like
.Fn clnt_create
except
.Fn clnt_tp_create
tries only one transport specified through
.Fa netconf .
.Fn clnt_tp_create
creates a client handle for the program
.Fa prognum ,
the version
.Fa versnum ,
and for the transport specified by
.Fa netconf .
Default options are set,
which can be changed using
.Fn clnt_control
calls.
The remote rpcbind service on the host
.Fa host
is consulted for the address of the remote service.
This routine returns
.Dv NULL
if it fails.
The
.Fn clnt_pcreateerror
routine can be used to print the reason for failure.
.It Fn clnt_vc_create
This routine creates an RPC
client for the remote program
.Fa prognum
and version
.Fa versnum ;
the client uses a connection-oriented transport.
The remote program is located at address
.Fa svcaddr .
The parameter
.Fa fildes
is an open and bound file descriptor.
The user may specify the size of the send and receive buffers
with the parameters
.Fa sendsz
and
.Fa recvsz ;
values of 0 choose suitable defaults.
This routine returns
.Dv NULL
if it fails.
The address
.Fa svcaddr
should not be
.Dv NULL
and should point to the actual address of the remote program.
.Fn clnt_vc_create
does not consult the remote rpcbind service for this information.
.It Xo
.Vt "struct rpc_createerr" Va rpc_createerr ;
.Xc
A global variable whose value is set by any RPC
client handle creation routine
that fails.
It is used by the routine
.Fn clnt_pcreateerror
to print the reason for the failure.
