MFC r228722:

In usr.sbin/yp_mkdb/yp_mkdb.c, cast some printf field width parameters
to int, cast time_t to intmax_t, and use the corresponding printf length
modifier.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Use __FBSDID over rcsid[]. Protect copyright[] where needed.

Spell void * as void * rather than caddr_t. This is complicated by the
fact that caddr_t is often misspelled as char *.

Apply the following mechanical transformations in preparation for
ansification and constification:

s{\s+__P\((\(.*?\))\)}{$1}g;
s{\(\s+}{\(}g;
s{\s+\)}{\)}g;
s{\s+,}{,}g;
s{(\s+)(for|if|switch|while)\(}{$1$2 \(}g;
s{return ([^\(].*?);}{return ($1);}g;
s{([\w\)])([!=+/\*-]?=)([\w\(+-])}{$1 $2 $3}g;

Also add $FreeBSD$ where needed.

MFC after: 1 week

Fix stupid disorder in previous commit. This was my own error, not
the mistake of the PR's originator.

The -f option stole the -d option's option string colon in the getopt
optstring.

PR: 13521
Submitted by: Andre Albsmeier <andre.albsmeier@mchp.siemens.de>

$Id$ -> $FreeBSD$

Modify yp_mkdb so that it only checks for bogus '+' and '-' characters
in source input if the -f flag is used, and modify Makefile.yp to only
use -f for the passwd, master.passwd and group maps. These should be
the only ones for which the + and - characters have special meaning
that make it important for us to avoid letting them into any of the map
databases. In some cases (namely the automounter maps) we have to allow
at least the - character through in order to create the map properly.

This closes PR #8699.

Remove `progname'.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Check for, warn about and reject lines with empty keys. You can't have
a database entry with a null key. These are often caused by spurious
blank lines in the map source file.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Add -b and -s flags for adding YP_INTERDOMAIN and YP_SECURE entries to
map databases. Also document said flags in the man page.

Adding YP_INTERDOMAIN to a map causes ypserv(8) to do a DNS lookup
when a yp_match() on the map fails. (This affects only the hosts.by*
maps; for all other maps it's ignored.) The YP_SECURE entry causes
ypserv(8) to restrict access to the map so that only clients making
requests from reserved ports can get at it.

Our ypserv doesn't currently support these features so they're silently
ignored for the moment, but this will change. :)

Update to pass new arguments now expected by the yp_dbwrite routines.
No functional changes.

This commit was generated by cvs2svn to compensate for changes in r15423,
which included commits to RCS files with non-trunk default branches.

Import the new yp_mkdb. This one does what the old one does, but is
hopefully less grotty. Differences include:

- An extra flag, -c, for sending a YPPROC_CLEAR to ypserv(8) (which
will become useful once I merge in the DB handle caching mods I've
been working on).
- Checks for and signals duplicate keys.
- Handles line continuations.

As of now, there is no more GNU YP code in the tree.
