Fix getpeereid
getpeereid fails because it uses an incorrect getsockopt call to obtain
the peer credentials on a AF_LOCAL socket. This in turn will cause all
RPC services to be registered with rpcbind to show up as having been
registered by "unknown".
This has a serious impact on security - a service owned by "unknown"
can essentially be unregistered (and thus replaced) by anyone.

Fix xp_raddr handling in svc_fd_create etc
Currently svc_fd_create tries to do some clever tricks
with IPv4/v6 address mapping.
This is broken for several reasons.
1. We don't want IPv4 based transport to look like IPv6
transports. Old applications compiled against tirpc
will expect AF_INET addresses, and are not equipped
to deal with AF_INET6.
2. There's a buffer overflow.
memcpy(&sin6, &ss, sizeof(ss));
copies a full struct sockaddr to a sockaddr_in6 on
the stack. Unlikely to be exploitable, but I wonder
if this ever worked....

Fix for taddr2addr conversion bug of local addresses
When converting af_local socket addresses in taddr2uaddr, an incorrect

Always make IPv6 sockets V6ONLY
Assume you have a netconfig file looking like this:
udp tpi_clts v inet udp - -
udp6 tpi_clts v inet6 udp - -
...
a call to svc_tli_create(... &someaddr, "udp") will fail to create an
IPv6 server socket. The problem is that on Linux, passive IPv6 sockets
will also accept packets/connections from IPv4, and will simply map
the sender's address to an IPv6 mapped IPv4 address. So if you want to
bind both a UDPv4 and UDPv6 socket to the same port, this will fail with
EADDRINUSE.
The way to avoid this behavior is to change the socket to V6ONLY,
which tells the kernel to avoid the autmatic mapping.
The change proposed in the patch below does this. I *think* this is
a good place to do this, as it will also fix applications that do not
use svc_tli_create() - such as rpcbind, which creates the sockets on
its own using __rpc_nconf2fd.
I think this also improves portability, as BSD code assumes BSD
behavior, where this mapping does not occur either.

Installation Instructions
*************************
Copyright (C) 1994-1996, 1999-2002, 2004-2013 Free Software Foundation,
Inc.
Copying and distribution of this file, with or without modification,
are permitted in any medium without royalty provided the copyright
notice and this notice are preserved. 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 time stamps 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 `<wchar.h>' 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.

LIBTIRPC 0.1 FROM SUN'S TIRPCSRC 2.3 29 Aug 1994
This package contains SunLib's implementation of transport-independent
RPC (TI-RPC) documentation. 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.

.Ft int
.Fn bindresvport "int sd" "struct sockaddr_in *sin"
.Ft int
.Fn bindresvport_sa "int sd" "struct sockaddr *sa"
.Sh 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.

.Ft void
.Fn des_setparity "char *key"
.Sh DESCRIPTION
The
.Fn ecb_crypt
and
.Fn cbc_crypt
functions
implement the
.Tn NBS
.Tn DES
(Data Encryption Standard).
These routines are faster and more general purpose than
.Xr crypt 3 .
They also are able to utilize
.Tn DES
hardware if it is available.
The
.Fn ecb_crypt
function
encrypts in
.Tn ECB
(Electronic Code Book)
mode, which encrypts blocks of data independently.
The
.Fn cbc_crypt
function
encrypts in
.Tn CBC
(Cipher Block Chaining)
mode, which chains together
successive blocks.
.Tn CBC
mode protects against insertions, deletions and
substitutions of blocks.
Also, regularities in the clear text will
not appear in the cipher text.
.Pp
Here is how to use these routines.
The first argument,
.Fa key ,
is the 8-byte encryption key with parity.
To set the key's parity, which for
.Tn DES
is in the low bit of each byte, use
.Fn des_setparity .
The second argument,
.Fa data ,
contains the data to be encrypted or decrypted.
The
third argument,
.Fa datalen ,
is the length in bytes of
.Fa data ,
which must be a multiple of 8.
The fourth argument,
.Fa mode ,
is formed by
.Em OR Ns 'ing
together some things.
For the encryption direction
.Em OR
in either
.Dv DES_ENCRYPT
or
.Dv DES_DECRYPT .
For software versus hardware
encryption,
.Em OR
in either
.Dv DES_HW
or
.Dv DES_SW .
If
.Dv DES_HW
is specified, and there is no hardware, then the encryption is performed
in software and the routine returns
.Er DESERR_NOHWDEVICE .
For
.Fn cbc_crypt ,
the
.Fa ivec
argument
is the 8-byte initialization
vector for the chaining.
It is updated to the next initialization
vector upon return.
.Sh ERRORS
.Bl -tag -width [DESERR_NOHWDEVICE] -compact
.It Bq Er DESERR_NONE
No error.
.It Bq Er DESERR_NOHWDEVICE
Encryption succeeded, but done in software instead of the requested hardware.
.It Bq Er DESERR_HWERR
An error occurred in the hardware or driver.
.It Bq Er DESERR_BADPARAM
Bad argument to routine.
.El
.Pp
Given a result status
.Va stat ,
the macro
.Fn DES_FAILED stat
is false only for the first two statuses.
.Sh AVAILABILITY
The
.Fn ecb_crypt ,

.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 .
The
.Fn getnetconfig
function
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.
The
.Fn getnetconfig
function
can be used to search the entire netconfig
file.
The
.Fn getnetconfig
function
returns
.Dv NULL
at the end of the file.
The
.Fa handlep
argument
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.
The
.Fn setnetconfig
function
must be called before the first call to
.Fn getnetconfig
and may be called at any other time.
The
.Fn setnetconfig
function
need not be called before a call to
.Fn getnetconfigent .
The
.Fn setnetconfig
function
returns a unique handle to be used by
.Fn getnetconfig .
.Pp
The
.Fn endnetconfig
function
should be called when processing is complete to release resources for reuse.
The
.Fa handlep
argument
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.
The
.Fn endnetconfig
function
may not be called before
.Fn setnetconfig .
.Pp
The
.Fn getnetconfigent
function
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
The
.Fn freenetconfigent
function
frees the netconfig structure pointed to by
.Fa netconfigp
(previously returned by
.Fn getnetconfigent ) .
.Pp
The
.Fn nc_perror
function
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
The
.Fn nc_sperror
function
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
The
.Fn nc_perror
and
.Fn nc_sperror
functions
can also be used with the
.Ev NETPATH
access routines defined in
.Xr getnetpath 3 .
.Sh RETURN VALUES
The
.Fn setnetconfig
function
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
The
.Fn getnetconfig
function
returns a pointer to the current entry in the netconfig
database, formatted as a
.Ft "struct netconfig" .
The
.Fn getnetconfig
function
returns
.Dv NULL
at the end of the file, or upon failure.
.Pp
The
.Fn endnetconfig
function
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
The
.Fn nc_sperror
function
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.

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.
The
.Fn getnetpath
function
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 .
The
.Fn setnetpath
function
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
The
.Fn getnetpath
function
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
The
.Fn endnetpath
function
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
The
.Fn setnetpath
function
returns a handle that is used by
.Fn getnetpath .
In case of an error,
.Fn setnetpath
returns
.Dv NULL .
.Pp
The
.Fn endnetpath
function
returns 0 on success and \-1 on failure
(for example, if
.Fn setnetpath
was not called previously).
The
.Fn nc_perror
or
.Fn nc_sperror
function
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 DESCRIPTION
The

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 {

.Sh NAME
.Nm rpc
.Nd library routines for remote procedure calls
.Sh SYNOPSIS
.In rpc/rpc.h
.In netconfig.h
.Sh DESCRIPTION
These
routines allow C language programs to make procedure
calls on other machines across a network.
First, the client sends a request to the server.
On receipt of the request, the server calls a dispatch routine
to perform the requested service, and then sends back a reply.
.Pp
All
RPC routines require the header
.In rpc/rpc.h .
Routines that take a
.Vt "struct netconfig"
also require that
.In netconfig.h
be included.
.Sh Nettype
Some of the high-level
RPC interface routines take a
.Fa nettype
string as one of the arguments
(for example,
.Fn clnt_create ,
.Fn svc_create ,
.Fn rpc_reg ,
.Fn rpc_call ) .
This string defines a class of transports which can be used
for a particular application.
.Pp
The
.Fa nettype
argument
can be one of the following:
.Bl -tag -width datagram_v
.It netpath
Choose from the transports which have been
indicated by their token names in the
.Ev NETPATH
environment variable.
.Ev NETPATH
is unset or
.Dv NULL ,
it defaults to
.Qq visible .
.Qq netpath
is the default
.Fa nettype .
.It visible
Choose the transports which have the visible flag (v)
set in the
.Pa /etc/netconfig
file.
.It circuit_v
This is same as
.Qq visible
except that it chooses only the connection oriented transports
(semantics
.Qq tpi_cots
or
.Qq tpi_cots_ord )
from the entries in the
.Pa /etc/netconfig
file.
.It datagram_v
This is same as
.Qq visible
except that it chooses only the connectionless datagram transports
(semantics
.Qq tpi_clts )
from the entries in the
.Pa /etc/netconfig
file.
.It circuit_n
This is same as
.Qq netpath
except that it chooses only the connection oriented datagram transports
(semantics
.Qq tpi_cots
or
.Qq tpi_cots_ord ) .
.It datagram_n
This is same as
.Qq netpath
except that it chooses only the connectionless datagram transports
(semantics
.Qq tpi_clts ) .
.It udp
This refers to Internet UDP, both version 4 and 6.
.It tcp
This refers to Internet TCP, both version 4 and 6.
.El
.Pp
If
.Fa nettype
is
.Dv NULL ,
it defaults to
.Qq netpath .
The transports are tried in left to right order in the
.Ev NETPATH
variable or in top to down order in the
.Pa /etc/netconfig
file.

.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 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 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.
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 clnt_pcreateerror
to print the reason for the failure.

.Fa "struct svc_req *req"
.Fa "gss_cred_id_t deleg"
.Fa "gss_ctx_id_t gss_context"

.Fc
.Ft bool_t
.Fn rpc_gss_set_callback "rpc_gss_callback_t *cb"
.Sh DESCRIPTION
Register a function which will be called when new security contexts
are created on a server.
This function will be called on the first RPC request which uses that
context and has the opportunity of rejecting the request (for instance
after matching the request credentials to an access control list).
To accept the new security context, the callback should return
.Dv TRUE ,
otherwise
.Dv FALSE .
If the callback accepts a context, it becomes responsible for the
lifetime of the delegated client credentials (if any).
.Pp
It is also possible to 'lock' the values of service and quality of
protection used by the context.
If a context is locked, any subsequent requests which use different
values for service and quality of protection will be rejected.
.Sh PARAMETERS
.Bl -tag -width ".It gss_context"
.It cb
A structure containing the RPC program and version for this callback
and a function which will be called when new contexts are created for
the given RPC program and version
.It req
The RPC request using the new context
.It deleg
GSS-API delegated credentials (if any)
.It gss_context
The GSS-API context
.It lock
A structure used to enforce a particular QOP and service. Set
.Fa lock->locked
to
.Dv TRUE
to lock the service and QOP values
.It cookie
The callback function may set
.Fa *cookie
to any pointer sized value.
This value can be accessed during the lifetime of the context via
.Fn rpc_gss_getcred .
.El
.Sh RETURN VALUES
Returns
.Dv TRUE
if the callback was registered successfully or
.Dv FALSE
otherwise
.Sh AVAILABILITY
The
.Fn rpc_gss_set_callback
function is part of libtirpc.

.Sh AUTHORS
This
manual page was written by
.An Doug Rabson Aq dfr@FreeBSD.org .
.Sh BUGS
There is no mechanism for informing a server when a security context
has been deleted.
This makes it difficult to allocate resources (e.g. to return via the
callback's
.Fa cookie
argument).

.Sh DESCRIPTION
These routines are part of the
.Tn RPC
library. 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 it succeeds and
.Dv FALSE
if it fails.
Inverse of
.Fn netname2user .

.Sh DESCRIPTION
These routines are part of the
RPC
library which allows C language programs to make procedure
calls on other machines across the network.
.Pp
These routines are associated with the server side of the
RPC mechanism.
Some of them are called by the server side dispatch function,
while others
(such as
.Fn svc_run )
are called when the server is initiated.
.\" .Pp
.\" In the current implementation, the service transport handle,
.\" .Dv SVCXPRT ,
.\" contains a single data area for decoding arguments and encoding results.
.\" Therefore, this structure cannot be freely shared between threads that call
.\" functions that do this.
.\" Routines on this page that are affected by this
.\" restriction are marked as unsafe for MT applications.
.Sh Routines
See
.Xr rpc 3
for the definition of the
.Vt SVCXPRT
data structure.
.Bl -tag -width __svc_getcallercreds()
.It Fn svc_dg_enablecache
This function allocates a duplicate request cache for the
service endpoint
.Fa xprt ,
large enough to hold
.Fa cache_size
entries.
Once enabled, there is no way to disable caching.
This routine returns 0 if space necessary for a cache of the given size
was successfully allocated, and 1 otherwise.
.It Fn svc_exit
This function, when called by any of the RPC server procedure or
otherwise, causes
.Fn svc_run
to return.
.Pp
As currently implemented,
.Fn svc_exit
zeroes the
.Va svc_fdset
global variable.
If RPC server activity is to be resumed,
services must be reregistered with the RPC library
either through one of the
.Xr rpc_svc_create 3
functions, or using
.Fn xprt_register .
The
.Fn svc_exit
function
has global scope and ends all RPC server activity.
.It Xo
.Vt fd_set Va svc_fdset
.Xc
A global variable reflecting the
RPC server's read file descriptor bit mask; it is suitable as an argument
to the
.Xr select 2
system call.
This is only of interest
if service implementors do not call
.Fn svc_run ,
but rather do their own asynchronous event processing.
This variable is read-only (do not pass its address to
.Xr select 2 ! ) ,
yet it may change after calls to
.Fn svc_getreqset
or any creation routines.
.It Fn svc_freeargs
A function macro that frees any data allocated by the
RPC/XDR system when it decoded the arguments to a service procedure
using
.Fn svc_getargs .
This routine returns
.Dv TRUE
if the results were successfully
freed, and
.Dv FALSE
otherwise.
.It Fn svc_getargs
A function macro that decodes the arguments of an
RPC request associated with the RPC
service transport handle
.Fa xprt .
The
.Fa in
argument
is the address where the arguments will be placed;
.Fa inproc
is the XDR
routine used to decode the arguments.
This routine returns
.Dv TRUE
if decoding succeeds, and
.Dv FALSE
otherwise.
.It Fn svc_getreq_common
This routine is called to handle a request on the given
file descriptor.
.It Fn svc_getreq_poll
This routine is only of interest if a service implementor
does not call
.Fn svc_run ,
but instead implements custom asynchronous event processing.
It is called when
.Xr poll 2
has determined that an RPC request has arrived on some RPC
file descriptors;
.Fa pollretval
is the return value from
.Xr poll 2
and
.Fa pfdp
is the array of
.Vt pollfd
structures on which the
.Xr poll 2
was done.
It is assumed to be an array large enough to
contain the maximal number of descriptors allowed.
.It Fn svc_getreqset
This routine is only of interest if a service implementor
does not call
.Fn svc_run ,
but instead implements custom asynchronous event processing.
It is called when
.Xr poll 2
has determined that an RPC
request has arrived on some RPC file descriptors;
.Fa rdfds
is the resultant read file descriptor bit mask.
The routine returns when all file descriptors
associated with the value of
.Fa rdfds
have been serviced.
.It Fn svc_getrpccaller
The approved way of getting the network address of the caller
of a procedure associated with the
RPC service transport handle
.Fa xprt .
.It Fn __svc_getcallercreds
.Em Warning :
this macro is specific to
.Fx
and thus not portable.
This macro returns a pointer to a
.Vt cmsgcred
structure, defined in
.In sys/socket.h ,
identifying the calling client.
This only works if the client is
calling the server over an
.Dv AF_LOCAL
socket.
.It Xo
.Vt struct pollfd Va svc_pollset[FD_SETSIZE] ;
.Xc
.Va svc_pollset
is an array of
.Vt pollfd
structures derived from
.Va svc_fdset[] .
It is suitable as an argument to the
.Xr poll 2
system call.
The derivation of
.Va svc_pollset
from
.Va svc_fdset
is made in the current implementation in
.Fn svc_run .
Service implementors who do not call
.Fn svc_run
and who wish to use this array must perform this derivation themselves.
.It Fn svc_run
This routine never returns.
It waits for RPC
requests to arrive, and calls the appropriate service
procedure using
.Fn svc_getreq_poll
when one arrives.
This procedure is usually waiting for the
.Xr poll 2
system call to return.
.It Fn svc_sendreply
Called by an RPC service's dispatch routine to send the results of a
remote procedure call.
The
.Fa xprt
argument
is the request's associated transport handle;
.Fa outproc
is the XDR
routine which is used to encode the results; and
.Fa out
is the address of the results.
This routine returns
.Dv TRUE
if it succeeds,
.Dv FALSE
otherwise.

.Sh DESCRIPTION
These routines are part of the RPC
library which allows C language programs to make procedure
calls on servers across the network.
These routines deal with the creation of service handles.
Once the handle is created, the server can be invoked by calling
.Fn svc_run .
.Sh Routines
See
.Xr rpc 3
for the definition of the
.Vt SVCXPRT
data structure.
.Bl -tag -width XXXXX
.It Fn svc_control
A function to change or retrieve various information
about a service object.
The
.Fa req
argument
indicates the type of operation and
.Fa info
is a pointer to the information.
The supported values of
.Fa req ,
their argument types, and what they do are:
.Bl -tag -width SVCGET_XID
.It Dv SVCGET_VERSQUIET
If a request is received for a program number
served by this server but the version number
is outside the range registered with the server,
an
.Dv RPC_PROGVERSMISMATCH
error will normally
be returned.
The
.Fa info
argument
should be a pointer to an
integer.
Upon successful completion of the
.Dv SVCGET_VERSQUIET
request,
.Fa *info
contains an
integer which describes the server's current
behavior: 0 indicates normal server behavior
(that is, an
.Dv RPC_PROGVERSMISMATCH
error
will be returned); 1 indicates that the out of
range request will be silently ignored.
.It Dv SVCSET_VERSQUIET
If a request is received for a program number
served by this server but the version number
is outside the range registered with the server,
an
.Dv RPC_PROGVERSMISMATCH
error will normally
be returned.
It is sometimes desirable to
change this behavior.
The
.Fa info
argument
should be a
pointer to an integer which is either 0
(indicating normal server behavior - an
.Dv RPC_PROGVERSMISMATCH
error will be returned),
or 1 (indicating that the out of range request
should be silently ignored).
.El
.It Fn svc_create
The
.Fn svc_create
function
creates server handles for all the transports
belonging to the class
.Fa nettype .
The
.Fa nettype
argument
defines a class of transports which can be used
for a particular application.
The transports are tried in left to right order in
.Ev NETPATH
variable or in top to bottom order in the netconfig database.
If
.Fa nettype
is
.Dv NULL ,
it defaults to
.Qq netpath .
.Pp
The
.Fn svc_create
function
registers itself with the rpcbind
service (see
.Xr rpcbind 8 ) .
The
.Fa dispatch
function
is called when there is a remote procedure call for the given
.Fa prognum
and
.Fa versnum ;
this requires calling
.Fn svc_run
(see
.Fn svc_run
in
.Xr rpc_svc_reg 3 ) .
If
.Fn svc_create
succeeds, it returns the number of server
handles it created,
otherwise it returns 0 and an error message is logged.
.It Fn svc_destroy
A function macro that destroys the RPC
service handle
.Fa xprt .
Destruction usually involves deallocation
of private data structures,
including
.Fa xprt
itself.
Use of
.Fa xprt
is undefined after calling this routine.
.It Fn svc_dg_create
This routine creates a connectionless RPC
service handle, and returns a pointer to it.
This routine returns
.Dv NULL
if it fails, and an error message is logged.
The
.Fa sendsz
and
.Fa recvsz
arguments
are arguments used to specify the size of the buffers.
If they are 0, suitable defaults are chosen.
The file descriptor
.Fa fildes
should be open and bound.
The server is not registered with
.Xr rpcbind 8 .
.Pp
Warning:
since connectionless-based RPC
messages can only hold limited amount of encoded data,
this transport cannot be used for procedures
that take large arguments or return huge results.
.It Fn svc_fd_create
This routine creates a service on top of an open and bound file descriptor,
and returns the handle to it.
Typically, this descriptor is a connected file descriptor for a
connection-oriented transport.
The
.Fa sendsz
and
.Fa recvsz
arguments
indicate sizes for the send and receive buffers.
If they are 0, reasonable defaults are chosen.
This routine returns
.Dv NULL
if it fails, and an error message is logged.
.It Fn svc_raw_create
This routine creates an RPC
service handle and returns a pointer to it.
The transport is really a buffer within the process's
address space, so the corresponding RPC
client should live in the same address space;
(see
.Fn clnt_raw_create
in
.Xr rpc_clnt_create 3 ) .
This routine allows simulation of RPC and acquisition of
RPC overheads (such as round trip times),
without any kernel and networking interference.
This routine returns
.Dv NULL
if it fails, and an error message is logged.
.Pp
Note:
.Fn svc_run
should not be called when the raw interface is being used.
.It Fn svc_tli_create
This routine creates an RPC
server handle, and returns a pointer to it.
The
.Fa fildes
argument
is the file descriptor on which the service is listening.
If
.Fa fildes
is
.Dv RPC_ANYFD ,
it opens a file descriptor on the transport specified by
.Fa netconf .
If the file descriptor is unbound and
.Fa bindaddr
is not
.Dv NULL ,
.Fa fildes
is bound to the address specified by
.Fa bindaddr ,
otherwise
.Fa fildes
is bound to a default address chosen by the transport.
.Pp
Note: the
.Vt t_bind
structure comes from the TLI/XTI SysV interface, which
.Nx
does not use.
The structure is defined in
.In rpc/types.h
for compatibility as:
.Bd -literal
struct t_bind {
struct netbuf addr; /* network address, see rpc(3) */
unsigned int qlen; /* queue length (for listen(2)) */
};
.Ed
.Pp
In the case where the default address is chosen,
the number of outstanding connect requests is set to 8
for connection-oriented transports.
The user may specify the size of the send and receive buffers
with the arguments
.Fa sendsz
and
.Fa recvsz ;
values of 0 choose suitable defaults.
This routine returns
.Dv NULL
if it fails,
and an error message is logged.
The server is not registered with the
.Xr rpcbind 8
service.
.It Fn svc_tp_create
The
.Fn svc_tp_create
function
creates a server handle for the network
specified by
.Fa netconf ,
and registers itself with the rpcbind service.
The
.Fa dispatch
function
is called when there is a remote procedure call
for the given
.Fa prognum
and
.Fa versnum ;
this requires calling
.Fn svc_run .
The
.Fn svc_tp_create
function
returns the service handle if it succeeds,
otherwise a
.Dv NULL
is returned and an error message is logged.
.It Fn svc_vc_create
This routine creates a connection-oriented RPC
service and returns a pointer to it.
This routine returns
.Dv NULL
if it fails, and an error message is logged.
The users may specify the size of the send and receive buffers
with the arguments
.Fa sendsz
and
.Fa recvsz ;
values of 0 choose suitable defaults.
The file descriptor
.Fa fildes
should be open and bound.
The server is not registered with the
.Xr rpcbind 8
service.

.Sh DESCRIPTION
These routines are a part of the RPC
library which allows the RPC
servers to register themselves with rpcbind
(see
.Xr rpcbind 8 ) ,
and associate the given program and version
number with the dispatch function.
When the RPC server receives a RPC request, the library invokes the
dispatch routine with the appropriate arguments.
.Sh Routines
See
.Xr rpc 3
for the definition of the
.Vt SVCXPRT
data structure.
.Bl -tag -width XXXXX
.It Fn rpc_reg
Register program
.Fa prognum ,
procedure
.Fa procname ,
and version
.Fa versnum
with the RPC
service package.
If a request arrives for program
.Fa prognum ,
version
.Fa versnum ,
and procedure
.Fa procnum ,
.Fa procname
is called with a pointer to its argument(s);
.Fa procname
should return a pointer to its static result(s);
.Fa inproc
is the XDR function used to decode the arguments while
.Fa outproc
is the XDR function used to encode the results.
Procedures are registered on all available transports of the class
.Fa nettype .
See
.Xr rpc 3 .
This routine returns 0 if the registration succeeded,
\-1 otherwise.
.It Fn svc_reg
Associates
.Fa prognum
and
.Fa versnum
with the service dispatch procedure,
.Fa dispatch .
If
.Fa netconf
is
.Dv NULL ,
the service is not registered with the
.Xr rpcbind 8
service.
If
.Fa netconf
is non-zero,
then a mapping of the triple
.Bq Fa prognum , versnum , netconf->nc_netid
to
.Fa xprt->xp_ltaddr
is established with the local rpcbind
service.
.Pp
The
.Fn svc_reg
routine returns 1 if it succeeds,
and 0 otherwise.
.It Fn svc_unreg
Remove from the rpcbind
service, all mappings of the triple
.Bq Fa prognum , versnum , No all-transports
to network address
and all mappings within the RPC service package
of the double
.Bq Fa prognum , versnum
to dispatch routines.
.It Fn svc_auth_reg
Registers the service authentication routine
.Fa handler
with the dispatch mechanism so that it can be
invoked to authenticate RPC requests received
with authentication type
.Fa cred_flavor .
This interface allows developers to add new authentication
types to their RPC applications without needing to modify
the libraries.
Service implementors usually do not need this routine.
.Pp
Typical service application would call
.Fn svc_auth_reg
after registering the service and prior to calling
.Fn svc_run .
When needed to process an RPC credential of type
.Fa cred_flavor ,
the
.Fa handler
procedure will be called with two arguments,
.Fa "struct svc_req *rqst"
and
.Fa "struct rpc_msg *msg" ,
and is expected to return a valid
.Vt "enum auth_stat"
value.
There is no provision to change or delete an authentication handler
once registered.
.Pp
The
.Fn svc_auth_reg
routine returns 0 if the registration is successful,
1 if
.Fa cred_flavor
already has an authentication handler registered for it,
and \-1 otherwise.
.It Fn xprt_register
After RPC service transport handle
.Fa xprt
is created, it is registered with the RPC
service package.
This routine modifies the global variable
.Va svc_fdset
(see
.Xr rpc_svc_calls 3 ) .
Service implementors usually do not need this routine.
.It Fn xprt_unregister
Before an RPC service transport handle
.Fa xprt
is destroyed, it unregisters itself with the
RPC service package.
This routine modifies the global variable
.Va svc_fdset
(see
.Xr rpc_svc_calls 3 ) .
Service implementors usually do not need this routine.

and their universal addresses.
.Sh Routines
.Bl -tag -width XXXXX
.It Fn rpcb_getmaps
An interface to the rpcbind service,
which returns a list of the current
RPC program-to-address mappings on
.Fa host .
It uses the transport specified through
.Fa netconf
to contact the remote rpcbind
service on
.Fa host .
This routine will return
.Dv NULL ,
if the remote rpcbind could not be contacted.
.It Fn rpcb_getaddr
An interface to the rpcbind
service, which finds the address of the service on
.Fa host
that is registered with program number
.Fa prognum ,
version
.Fa versnum ,
and speaks the transport protocol associated with
.Fa netconf .
The address found is returned in
.Fa svcaddr .
The
.Fa svcaddr
argument
should be preallocated.
This routine returns
.Dv TRUE
if it succeeds.
A return value of
.Dv FALSE
means that the mapping does not exist
or that the RPC
system failed to contact the remote
rpcbind service.
In the latter case, the global variable
.Va rpc_createerr
(see
.Xr rpc_clnt_create 3 )
contains the
RPC status.
.It Fn rpcb_gettime
This routine returns the time on
.Fa host
in
.Fa timep .
If
.Fa host
is
.Dv NULL ,
.Fn rpcb_gettime
returns the time on its own machine.
This routine returns
.Dv TRUE
if it succeeds,
.Dv FALSE
if it fails.
The
.Fn rpcb_gettime
function
can be used to synchronize the time between the
client and the remote server.
.It Fn rpcb_rmtcall
An interface to the rpcbind service, which instructs
rpcbind on
.Fa host
to make an RPC
call on your behalf to a procedure on that host.
The
.Fn netconfig
structure should correspond to a connectionless transport.
The
.Fa svcaddr
argument
will be modified to the server's address if the procedure succeeds
(see
.Fn rpc_call
and
.Fn clnt_call
in
.Xr rpc_clnt_calls 3
for the definitions of other arguments).
.Pp
This procedure should normally be used for a
.Dq ping
and nothing else.
This routine allows programs to do lookup and call, all in one step.
.Pp
Note: Even if the server is not running
.Fn rpcb_rmtcall
does not return any error messages to the caller.
In such a case, the caller times out.
.Pp
Note:
.Fn rpcb_rmtcall
is only available for connectionless transports.
.It Fn rpcb_set
An interface to the rpcbind
service, which establishes a mapping between the triple
.Bq Fa prognum , versnum , netconf->nc_netid
and
.Fa svcaddr
on the machine's rpcbind
service.
The value of
.Fa nc_netid
must correspond to a network identifier that is defined by the
netconfig database.
This routine returns
.Dv TRUE
if it succeeds,
.Dv FALSE
otherwise.
(See also
.Fn svc_reg
in
.Xr rpc_svc_calls 3 . )
If there already exists such an entry with rpcbind,
.Fn rpcb_set
will fail.
.It Fn rpcb_unset
An interface to the rpcbind
service, which destroys the mapping between the triple
.Bq Fa prognum , versnum , netconf->nc_netid
and the address on the machine's rpcbind
service.
If
.Fa netconf
is
.Dv NULL ,
.Fn rpcb_unset
destroys all mapping between the triple
.Bq Fa prognum , versnum , No all-transports
and the addresses on the machine's rpcbind service.
This routine returns
.Dv TRUE
if it succeeds,
.Dv FALSE
otherwise.
Only the owner of the service or the super-user can destroy the mapping.

.Nm RPCSEC_GSS
.Nd "GSS-API based authentication for RPC"
.Sh SYNOPSIS
.In rpc/rpcsec_gss.h
.Sh DESCRIPTION
.Nm
is a security mechanism for the RPC protocol.
It uses the Generic Security Service API (GSS-API) to establish a
security context between a client and a server and to ensure that all
subsequent communication between client and server are properly
authenticated.
Optionally, extra protection can be applied to the connection.
The integrity service uses checksums to ensure that all data sent by
a peer is received without modification.
The privacy service uses encryption to ensure that no third party can
access the data for a connection.
.Pp
To use this system, an application must first use
.Fn rpc_gss_seccreate
to establish a security context.
.Sh DATA STRUCTURES

/*
* auth_time.c
*
* This module contains the private function __rpc_get_time_offset()
* which will return the difference in seconds between the local system's
* notion of time and a remote server's notion of time. This must be
* possible without calling any functions that may invoke the name
* service. (netdir_getbyxxx, getXbyY, etc). The function is used in the
* synchronize call of the authdes code to synchronize clocks between
* NIS+ clients and their servers.
*
* Note to minimize the amount of duplicate code, portions of the
* synchronize() function were folded into this code, and the synchronize
* call becomes simply a wrapper around this function. Further, if this
* function is called with a timehost it *DOES* recurse to the name
* server so don't use it in that mode if you are doing name service code.
*
* Copyright (c) 1992 Sun Microsystems Inc.
* All rights reserved.
*
* Side effects :
* When called a client handle to a RPCBIND process is created
* and destroyed. Two strings "netid" and "uaddr" are malloc'd
* and returned. The SIGALRM processing is modified only if
* needed to deal with TCP connections.

* return immediately to the client even though the call was not necessarily
* sent. The batching occurs if the results' xdr routine is NULL (0) AND
* the rpc timeout value is zero (see clnt.h, rpc).

* 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
* return message. Batched calls that produce many result messages can
* deadlock (netlock) the client and the server....

* IP and FP

*
* The output has been subject to swaps of the form
* 0 1 -> 3 1 but the odd and even bits have been put into
* 2 3 2 0
* different words. The main trick is to remember that
* t=((l>>size)^r)&(mask);
* r^=t;
* l^=(t<<size);
* can be used to swap and move bits between words.
*
* So l = 0 1 2 3 r = 16 17 18 19
* 4 5 6 7 20 21 22 23
* 8 9 10 11 24 25 26 27
* 12 13 14 15 28 29 30 31
* becomes (for size == 2 and mask == 0x3333)
* t = 2^16 3^17 -- -- l = 0 1 16 17 r = 2 3 18 19
* 6^20 7^21 -- -- 4 5 20 21 6 7 22 23
* 10^24 11^25 -- -- 8 9 24 25 10 11 24 25
* 14^28 15^29 -- -- 12 13 28 29 14 15 28 29
*
* Thanks for hints from Richard Outerbridge - he told me IP&FP
* could be done in 15 xor, 10 shifts and 5 ands.
* When I finally started to think of the problem in 2D
* I first got ~42 operations without xors. When I remembered
* how to use xors I got it to its final state.
