This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same timestamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + 'configure' can determine that directory automatically. + +'--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: for + more details, including other options available for fine-tuning the + installation locations. + +'--no-create' +'-n' + Run the configure checks, but stop before creating any output + files. + +'configure' also accepts some other, not widely useful, options. Run +'configure --help' for more details. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..3f60637 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,52 @@ +SUBDIRS = src man doc +ACLOCAL_AMFLAGS = -I m4 + +noinst_HEADERS = tirpc/reentrant.h \ + tirpc/getpeereid.h \ + tirpc/libc_private.h \ + tirpc/un-namespace.h + +nobase_include_HEADERS = tirpc/netconfig.h \ + tirpc/rpcsvc/crypt.x \ + tirpc/rpcsvc/crypt.h \ + tirpc/rpc/xdr.h \ + tirpc/rpc/types.h \ + tirpc/rpc/svc_soc.h \ + tirpc/rpc/svc.h \ + tirpc/rpc/svc_dg.h \ + tirpc/rpc/svc_auth.h \ + tirpc/rpc/svc_mt.h \ + tirpc/rpc/rpc_msg.h \ + tirpc/rpc/rpc.h \ + tirpc/rpc/rpcent.h \ + tirpc/rpc/rpc_com.h \ + tirpc/rpc/rpcb_prot.x \ + tirpc/rpc/rpcb_prot.h \ + tirpc/rpc/rpcb_clnt.h \ + tirpc/rpc/raw.h \ + tirpc/rpc/pmap_rmt.h \ + tirpc/rpc/pmap_prot.h \ + tirpc/rpc/pmap_clnt.h \ + tirpc/rpc/nettype.h \ + tirpc/rpc/key_prot.h \ + tirpc/rpc/des.h \ + tirpc/rpc/des_crypt.h \ + tirpc/rpc/clnt_stat.h \ + tirpc/rpc/clnt_soc.h \ + tirpc/rpc/clnt.h \ + tirpc/rpc/auth_unix.h \ + tirpc/rpc/auth_des.h \ + tirpc/rpc/auth.h + +if GSS +nobase_include_HEADERS += \ + tirpc/rpc/rpcsec_gss.h \ + tirpc/rpc/auth_gss.h \ + tirpc/rpc/svc_auth_gss.h +endif + +pkgconfigdir=$(libdir)/pkgconfig +pkgconfig_DATA = libtirpc.pc + +CLEANFILES = cscope.* *~ +DISTCLEANFILES = Makefile.in libtirpc*.tar.gz diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..2551e24 --- /dev/null +++ b/Makefile.in @@ -0,0 +1,958 @@ +# Makefile.in generated by automake 1.16.5 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2021 Free Software Foundation, Inc. + +# This Makefile.in is free software;

This library forms a piece of the base of Open Network +Computing (ONC), and is derived directly from the Solaris 2.3 source. + +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 was a native source release, compatible for +building on Solaris 2.3. It had been ported from FreeBSD 5.2.1 to GNU/Linux +in 2004. + +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. + +WHAT'S NEW IN THIS RELEASE: TIRPCSRC 2.3 FROM SUN + +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. + diff --git a/THANKS b/THANKS new file mode 100644 index 0000000..cea8ee3 --- /dev/null +++ b/THANKS @@ -0,0 +1,6 @@ + Thanks to for + +Aurelien Charbon TI-RPC portage from NetBSD + +BSD Communauty TI-RPC improvement from Sun implementation + diff --git a/TODO b/TODO new file mode 100644 index 0000000..6f62665 --- /dev/null +++ b/TODO @@ -0,0 +1,3 @@ +* Support of DES & other security part +* Provide tests +* rpcgen command missing diff --git a/VERSION b/VERSION new file mode 100644 index 0000000..5ee5442 --- /dev/null +++ b/VERSION @@ -0,0 +1,7 @@ +# This file is used by configure to get version information +# +PKG_MAJOR=0 +PKG_MINOR=1 +PKG_REVISION=11 +PKG_BUILD=0 + diff --git a/aclocal.m4 b/aclocal.m4 new file mode 100644 index 0000000..ad84603 --- /dev/null +++ b/aclocal.m4 @@ -0,0 +1,10215 @@ +# generated automatically by aclocal 1.16.5 -*- Autoconf -*- + +# Copyright (C) 1996-2021 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.71],, +[m4_warning([this file was generated for autoconf 2.71. +You have another version of autoconf.

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is +# needed for multi-threaded programs (defaults to the value of CC +# respectively CXX otherwise). (This is necessary on e.g. AIX to use the +# special cc_r/CC_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also to link with them as well. For example, you might link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threaded programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# CXX="$PTHREAD_CXX" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.

DESCRIPTION +The +.Fn bindresvport +and +.Fn bindresvport_sa +functions +are used to bind a socket descriptor to a privileged +.Tn IP +port, that is, a +port number in the range 0-1023. +.Pp +If +.Fa sin +is a pointer to a +.Ft "struct sockaddr_in" +then the appropriate fields in the structure should be defined. +Note that +.Fa sin->sin_family +must be initialized to the address family of the socket, passed by +.Fa sd . +If +.Fa sin->sin_port +is +.Sq 0 +then an anonymous port (in the range 600-1023) will be +chosen, and if +.Xr bind 2 +is successful, the +.Fa sin->sin_port +will be updated to contain the allocated port. +.Pp +If +.Fa sin +is the +.Dv NULL +pointer, +an anonymous port will be allocated (as above). +However, there is no way for +.Fn bindresvport +to return the allocated port in this case. +.Pp +Only root can bind to a privileged port; this call will fail for any +other users. +.Pp +Function prototype of +.Fn bindresvport +is biased to +.Dv AF_INET +socket. +The +.Fn bindresvport_sa +function +acts exactly the same, with more neutral function prototype. +Note that both functions behave exactly the same, and +both support +.Dv AF_INET6 +sockets as well as +.Dv AF_INET +sockets. +.Sh RETURN VALUES +.Rv -std bindresvport +.Sh ERRORS +.Bl -tag -width Er +.It Bq Er EPFNOSUPPORT +If second argument was supplied, +and address family did not match between

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 arguments. +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 +.Fa inproc +argument +is the XDR function used to encode the procedure's arguments, 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). +The +.Fa tout +argument +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 +.Fa out +argument +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. +The +.Fn clnt_sperrno +function +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_spcreateerror +(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. +The +.Fn rpc_broadcast +function +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. +The +.Fa inittime +argument +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 +.Fa inproc +argument +is used to encode the procedure's arguments, 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). +The +.Fa nettype +argument +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

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. +The +.Fa req +argument +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 argument 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 "u_int32_t *" Ta "get RPC program version" +.It Dv CLSET_VERS Ta "u_int32_t *" Ta "set RPC program version" +.It Dv CLGET_XID Ta "u_int32_t *" Ta "get XID of previous call" +.It Dv CLSET_XID Ta "u_int32_t *" 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" +.It Dv CLSET_CONNECT Ta Vt "int *" Ta use Xr connect 2 +.El +.Pp +The retry timeout is the time that RPC +waits for the server to reply before retransmitting the request. +The +.Fn clnt_control +function +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 . +The +.Fa host +argument +identifies the name of the remote host where the server +is located. +The +.Fa nettype +argument +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. +The +.Fn clnt_create +function +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_timed +Generic client creation routine which is similar to +.Fn clnt_create +but which also has the additional argument +.Fa timeout +that specifies the maximum amount of time allowed for +each transport class tried. +In all other respects, the +.Fn clnt_create_timed +call behaves exactly like the +.Fn clnt_create +call. +.It Fn clnt_create_vers +Generic client creation routine which is similar to +.Fn clnt_create +but which also checks for the +version availability. +The +.Fa host +argument +identifies the name of the remote host where the server +is located. +The +.Fa nettype +argument +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. +The +.Fa vers_outp +argument +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_create_vers_timed +Generic client creation routine which is similar to +.Fn clnt_create_vers +but which also has the additional argument +.Fa timeout +that specifies the maximum amount of time allowed for +each transport class tried. +In all other respects, the +.Fn clnt_create_vers_timed +call behaves exactly like the +.Fn clnt_create_vers +call. +.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 +.Fa fildes +argument +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 +.Fa sendsz +and +.Fa recvsz +arguments; +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. +The +.Fn clnt_raw_create +function +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. +The +.Fa fildes +argument +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 +.Fa sendsz +and +.Fa recvsz +arguments; +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 . +The +.Fn clnt_tp_create +function +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_tp_create_timed +Like +.Fn clnt_tp_create +except +.Fn clnt_tp_create_timed +has the extra argument +.Fa timeout +which specifies the maximum time allowed for +the creation attempt to succeed. +In all other respects, the +.Fn clnt_tp_create_timed +call behaves exactly like the +.Fn clnt_tp_create +call. +.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 +.Fa fildes +argument +is an open and bound file descriptor. +The user may specify the size of the send and receive buffers +with the +.Fa sendsz +and +.Fa recvsz +arguments; +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. +The +.Fn clnt_vc_create +function +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

They implement +.Tn DES +Authentication. See +.Xr rpc 3 +for further details about +.Tn RPC . +.Pp +The +.Fn authdes_create +is the first of two routines which interface to the +.Tn RPC +secure authentication system, known as +.Tn DES +authentication. +The second is +.Fn authdes_getucred , +below. +.Pp +Note: the keyserver daemon +.Xr keyserv 8 +must be running for the +.Tn DES +authentication system to work. +.Pp +The +.Fn authdes_create +function, +used on the client side, returns an authentication handle that +will enable the use of the secure authentication system. +The first argument +.Fa name +is the network name, or +.Fa netname , +of the owner of the server process. +This field usually +represents a +.Fa hostname +derived from the utility routine +.Fn host2netname , +but could also represent a user name using +.Fn user2netname . +The second field is window on the validity of +the client credential, given in seconds. A small +window is more secure than a large one, but choosing +too small of a window will increase the frequency of +resynchronizations because of clock drift. +The third +argument +.Fa addr +is optional. If it is +.Dv NULL , +then the authentication system will assume +that the local clock is always in sync with the server's +clock, and will not attempt resynchronizations. +If an address +is supplied, however, then the system will use the address +for consulting the remote time service whenever +resynchronization +is required. +This argument is usually the +address of the +.Tn RPC +server itself. +The final argument +.Fa ckey +is also optional. If it is +.Dv NULL , +then the authentication system will +generate a random +.Tn DES +key to be used for the encryption of credentials. +If it is supplied, however, then it will be used instead. +.Pp +The +.Fn authdes_pk_create +function is identical to +.Fn authdes_create , +except that the public key needs to be provided at calling time and +will not looked up by this function itself. +.Pp +The +.Fn authdes_getucred +function, +the second of the two +.Tn DES +authentication routines, +is used on the server side for converting a +.Tn DES +credential, which is +operating system independent, into a +.Ux +credential. +This routine differs from utility routine +.Fn netname2user +in that +.Fn authdes_getucred +pulls its information from a cache, and does not have to do a +Yellow Pages lookup every time it is called to get its information. +.Pp +The +.Fn getnetname +function +installs the unique, operating-system independent netname of +the +caller in the fixed-length array +.Fa name . +Returns +.Dv TRUE +if it succeeds and +.Dv FALSE +if it fails. +.Pp +The +.Fn host2netname +function +converts from a domain-specific hostname to an +operating-system independent netname. +Returns +.Dv TRUE +if it succeeds and +.Dv FALSE +if it fails. +Inverse of +.Fn netname2host . +.Pp +The +.Fn key_decryptsession +function +is an interface to the keyserver daemon, which is associated +with +.Tn RPC Ns 's +secure authentication system +.Tn ( DES +authentication). +User programs rarely need to call it, or its associated routines +.Fn key_encryptsession , +.Fn key_gendes +and +.Fn key_setsecret . +System commands such as +.Xr login 1 +and the +.Tn RPC +library are the main clients of these four routines. +.Pp +The +.Fn key_decryptsession +function +takes a server netname and a +.Tn DES +key, and decrypts the key by +using the public key of the server and the secret key +associated with the effective uid of the calling process. It +is the inverse of +.Fn key_encryptsession . +.Pp +The +.Fn key_encryptsession +function +is a keyserver interface routine. +It +takes a server netname and a des key, and encrypts +it using the public key of the server and the secret key +associated with the effective uid of the calling process. It +is the inverse of +.Fn key_decryptsession . +.Pp +The +.Fn key_gendes +function +is a keyserver interface routine. +It +is used to ask the keyserver for a secure conversation key. +Choosing one +.Qq random +is usually not good enough, +because +the common ways of choosing random numbers, such as using the +current time, are very easy to guess. +.Pp +The +.Fn key_setsecret +function +is a keyserver interface routine. +It is used to set the key for +the effective +.Fa uid +of the calling process. +.Pp +The +.Fn netname2host +function +converts from an operating-system independent netname to a +domain-specific hostname. +Returns +.Dv TRUE +if it succeeds and +.Dv FALSE +if it fails. Inverse of +.Fn host2netname . +.Pp +The +.Fn netname2user +function +converts from an operating-system independent netname to a +domain-specific user ID. +Returns +.Dv TRUE +if it succeeds and +.Dv FALSE +if it fails. +Inverse of +.Fn user2netname . +.Pp +The +.Fn user2netname +function +converts from a domain-specific username to an operating-system +independent netname. +Returns +.Dv TRUE +if
