/*
* 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.
*
* NOTE: This code has had the crap beaten out it in order to convert
* it from TI-RPC back to TD-RPC for use on FreeBSD.

.Sh SYNOPSIS
.Fd #include <sys/types.h>
.Fd #include <netinet/in.h>
.Ft int
.Fn bindresvport "int sd" "struct sockaddr_in **sin"
.Sh DESCRIPTION
.Nm Bindresvport
is used to bind a socket descriptor to a privileged
.SM IP
.Tn IP
port, that is, a
port number in the range 0-1023.
The routine returns 0 if it is successful,
otherwise \-1 is returned and
.B errno
otherwise -1 is returned and
.Va errno
set to reflect the cause of the error.
.LP
.Pp
Only root can bind to a privileged port; this call will fail for any
other users.
.Pp
If the value of sin->sin_port is non-zero
.Fn bindresvport
will attempt to use that specific port. If it fails, it chooses another
privileged port automatically.

* 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....

.TH DES_CRYPT 3 "6 October 1987"
.SH NAME
des_crypt, ecb_crypt, cbc_crypt, des_setparity \- fast DES encryption
.SH SYNOPSIS
.nf
.B #include <des_crypt.h>

.B int ecb_crypt(key, data, datalen, mode)

.SH DESCRIPTION
.IX encryption cbc_crypt "" \fLcbc_crypt\fP
.IX "des encryption" cbc_crypt "DES encryption" \fLcbc_crypt\fP

.IX "des encryption" des_setparity "DES encryption" \fLdes_setparity\fP
.B ecb_crypt(\|)
and
.B cbc_crypt(\|)
implement the
.SM NBS
.SM DES
(Data Encryption Standard).
These routines are faster and more general purpose than
.BR crypt (3).
They also are able to utilize
.SM DES
hardware if it is available.
.B ecb_crypt(\|)
encrypts in
.SM ECB
(Electronic Code Book)
mode, which encrypts blocks of data independently.
.B cbc_crypt(\|)
encrypts in
.SM CBC
(Cipher Block Chaining)
mode, which chains together
successive blocks.
.SM CBC
mode protects against insertions, deletions and
substitutions of blocks. Also, regularities in the clear text will
not appear in the cipher text.
.LP
Here is how to use these routines. The first parameter,
.IR key ,
is the 8-byte encryption key with parity.
To set the key's parity, which for
.SM DES
is in the low bit of each byte, use
.IR des_setparity .
The second parameter,
.IR data ,
contains the data to be encrypted or decrypted. The
third parameter,
.IR datalen ,
is the length in bytes of
.IR data ,
which must be a multiple of 8. The fourth parameter,
.IR mode ,
is formed by
.SM OR\s0'ing
together some things. For the encryption direction 'or' in either
.SM DES_ENCRYPT
or
.SM DES_DECRYPT\s0.
For software versus hardware
encryption, 'or' in either
.SM DES_HW
or
.SM DES_SW\s0.
If
.SM DES_HW
is specified, and there is no hardware, then the encryption is performed
in software and the routine returns
.SM DESERR_NOHWDEVICE\s0.
For
.IR cbc_crypt ,
the parameter
.I ivec
is the the 8-byte initialization
vector for the chaining. It is updated to the next initialization
vector upon return.
.LP
.SH "SEE ALSO"
.BR des (1),
.BR crypt (3)
.SH DIAGNOSTICS
.PD 0
.TP 20
.SM DESERR_NONE
No error.
.TP
.SM DESERR_NOHWDEVICE
Encryption succeeded, but done in software instead of the requested hardware.
.TP
.SM DESERR_HWERR
An error occurred in the hardware or driver.
.TP
.SM DESERR_BADPARAM
Bad parameter to routine.
.PD
.LP
Given a result status
.IR stat ,
the macro
.SM DES_FAILED\c
.BR ( stat )
is false only for the first two statuses.
.SH RESTRICTIONS
These routines are not available in RPCSRC 4.0.
This information is provided to describe the DES interface expected by
Secure RPC.

.Fn getrpcport
returns the port number for version
.I versnum
.Fa versnum
of the RPC program
.I prognum
.Fa prognum
running on
.I host
.Fa host
and using protocol
.IR proto .
.Fa proto .
It returns 0 if it cannot contact the portmapper, or if
.I prognum
.Fa prognum
is not registered. If
.I prognum
.Fa prognum
is registered but not with version
.IR versnum ,
.Fa versnum ,
it will still return a port number (for some version of the program)
indicating that the program is indeed registered.
The version mismatch will be detected upon the first call to the service.

These routines are used to get public and secret keys from the
.SM YP
database.
.B getsecretkey(\|)
has an extra argument,
.IR passwd ,
which is used to decrypt the encrypted secret key stored in the database.
Both routines return 1 if they are successful in finding the key, 0 otherwise.
The keys are returned as
.SM NULL\s0-terminated,
hexadecimal strings. If the password supplied to
.B getsecretkey(\|)
fails to decrypt the secret key, the routine will return 1 but the
.I secretkey
argument will be a

.TH RPC 3N "16 February 1988"
.SH NAME
rpc_secure \- library routines for secure remote procedure calls
.SH SYNOPSIS AND DESCRIPTION
These routines are part of the RPC library. They implement DES
Authentication. See
.BR rpc (3N)
for further details about RPC.

.fi
.ft R
.IP
.B authdes_create(\|)
is the first of two routines which interface to the
.SM RPC
secure authentication system, known as
.SM DES
authentication.
The second is
.BR authdes_getucred(\|) ,
below. Note: the keyserver daemon
.BR keyserv (8C)
must be running for the
.SM DES
authentication system to work.
.IP
.BR authdes_create(\|) ,
used on the client side, returns an authentication handle that
will enable the use of the secure authentication system.
The first parameter
.I name
is the network name, or
.IR netname ,
of the owner of the server process. This field usually
represents a
.I hostname
derived from the utility routine
.BR host2netname ,
but could also represent a user name using
.BR 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
parameter
.I syncaddr
is optional. If it is
.SM NULL\s0,
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 parameter is usually the
address of the
.SM RPC
server itself. The final parameter
.I ckey
is also optional. If it is
.SM NULL\s0,
then the authentication system will
generate a random
.SM DES
key to be used for the encryption of credentials.
If it is supplied, however, then it will be used instead.

.ft R
.IP
.BR authdes_getucred(\|) ,
the second of the two
.SM DES
authentication routines,
is used on the server side for converting a
.SM DES
credential, which is
operating system independent, into a
.UX
credential. This routine differs from utility routine
.B netname2user
in that
.B 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.

.ft R
.IP
Convert from a domain-specific hostname to an
operating-system independent netname. Return
.SM TRUE
if it succeeds and

if it fails. Inverse of

.ft R
.IP
.B key_decryptsession(\|)
is an interface to the keyserver daemon, which is associated
with
.SM RPC\s0's
secure authentication system (\s-1DES\s0
authentication).
User programs rarely need to call it, or its associated routines
.BR key_encryptsession(\|) ,
.B key_gendes(\|)
and
.BR key_setsecret(\|) .
System commands such as
.B login
and the
.SM RPC
library are the main clients of these four routines.
.IP
.B key_decryptsession(\|)
takes a server netname and a des key, and decrypts the key by
using the the public key of the the server and the secret key
associated with the effective uid of the calling process. It
is the inverse of
.BR key_encryptsession(\|) .

.IP
.B key_encryptsession(\|)
is a keyserver interface routine. It
takes a server netname and a des key, and encrypts
it using the public key of the the server and the secret key
associated with the effective uid of the calling process. It
is the inverse of
.BR key_decryptsession(\|) .

.ft R
.IP
.B key_gendes(\|)
is a keyserver interface routine. It
is used to ask the keyserver for a secure conversation key.
Choosing one at \(lqrandom\(rq is usually not good enough,
because
the common ways of choosing random numbers, such as using the
current time, are very easy to guess.

.LP
.ft B
.nf
.sp .5
key_setsecret(key)

.B getnetname(\|)
installs the unique, operating-system independent netname of

.SH DESCRIPTION
.B rtime(\|)
consults the Internet Time Server at the address pointed to by
.I addrp
and returns the remote time in the
.B timeval
struct pointed to by
.IR timep .
Normally, the
.SM UDP
protocol is used when consulting the Time Server. The
.I timeout
parameter specifies how long the
routine should wait before giving
up when waiting for a reply. If
.I timeout
is specified as
.SM NULL\s0,
however, the routine will instead use
.SM TCP
and block until a reply is received from the time server.
.LP
The routine returns 0 if it is successful. Otherwise,
it returns \-1 and
.B errno
is set to reflect the cause of the error.

/*
* Usage:
* xprt = svcunix_create(sock, send_buf_size, recv_buf_size);
*
* Creates, registers, and returns a (rpc) unix based transporter.
* Once *xprt is initialized, it is registered as a transporter
* see (svc.h, xprt_register). This routine returns
* a NULL if a problem occurred.
*
* If sock<0 then a socket is created, else sock is used.
* If the socket, sock is not bound to a port then svcunix_create
* binds it to an arbitrary port. The routine then starts a unix
* listener on the socket's associated port. In any (successful) case,
* xprt->xp_sock is the registered socket number and xprt->xp_port is the
* associated port number.
*
* Since unix streams do buffered io similar to stdio, the caller can specify
* how big the send and receive buffers are via the second and third parms;
* 0 => use the system default.
