Two small tweaks:

- servers should be the first target listed in 'all:' in order for slave
servers to be updated correctly: yppush reads the ypservers map to figure
out where all the slaves are, so it needs to be loaded onto the master
ASAP.

- Fixed small bogon in publickey target which nobody has noticed since
we're not using the publickey.byname map yet.

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

Eek! When I added the YP_INTERDOMAIN and YP_SECURE support, I documented
and set the B and S variables here, but I forgot to actually add them to
the master.passwd and hosts.* targets. In other words, they weren't being
passed to yp_mkdb as needed.

This needs to go into 2.2; it doesn't break things a lot, but it leaves
your master.passwd maps available to unprivileged users without you
realizing it.

Add support for handling the YP_SECURE and YP_INTERDOMAIN keys from
any maps that may have them. If the YP_SECURE key is present, ypserv
will only allow access to the map from clients on reserved ports.
If the YP_INTERDOMAIN key is present, the server will do DNS lookups
for hostnames that it can't find in hosts.byname or hosts.byaddr.
This is the same as the -d flag (which is retained for backwards
compatibility) but it can be set on a per-map/per-domain basis.

Also modified /var/yp/Makefile to add YP_INTERDOMAIN to the hosts.*
maps and YP_SECURE to master.passwd.* maps by default.

Toss old mknetid script into the attic.

Adjust things slightly to support the new mknetid program.

and sends a YPPROC_CLEAR to the local ypserv. This will be used by
rpc.yppasswdd once I merge in the in-place update changes.

yp_access.c:

- Make the yp_access() function print RPC program and procedure numbers
that it doesn't know about in literal form. This will allow it to work
with other prgrams that it doesn't know about, like rpc.ypxfrd I'm going
to import shortly.

yp_dblookup.c:

- Take out the __inline keywords. They weren't really helping me anyway.

- Somehow I broke yp_next() when DB_CACHE wasn't #defined. Fix it.

- Also fix potential case where yp_next() might loop forever; make sure
it checks the return values of all the (dbp->seq)()/R_NEXT calls that
it does as well as comparing keys.

Use rcsid strings more consistently.

Make 'oldaddr' static in yp_access().

Use strcpy()/strcat() in yp_open_db_cache() instead of snprintf().
(Seems to be a little faster this way.)

Performance enhancements (I hope) and new stuff:

yp_dblookup.c:

- Implement database handle caching. What this means is that instead
of opening and closing map databases for each request, we open a
database and save the handle (and, if requested, the key index)
in an array. This saves a bit of overhead on things like repeated
YPPROC_NEXT calls, such as you'd get from getpwent(). Normally,
each YPPROC_NEXT would require open()ing the database, seeking
to the location supplied by the caller (which is time consuming with
hash databases as the R_CURSOR flag doesn't work), reading the
data, close()ing the database and then shipping the data off to
the caller. The system call overhead is prohibitive, especially
with very large maps. By caching the handle to an open database,
we elimitate at least the open()/close() system calls, as well
as the associated DB setup and tear-down operations, for a large
percentage of the time. This improves performance substantially at
the cost of consuming a little more memory than before.

Note that all the caching support is surrounded by #ifdef DB_CACHE
so that this same source module can still be used by other programs
that don't need it.

- Make yp_open_db() call yp_validdomain(). Doing it here saves cycles
when caching is enabled since a hit on the map cache list by
definition means that the domain being referenced is valid.

- Also make yp_open_db() check for exhaustion of file descriptors,
just in case.

yp_server.c:

- Reorganize things a little to take advantage of the database
handle caching. Add a call to yp_flush_all() in ypproc_clear_2_svc().

- Remove calls to yp_validdomain() from some of the service procedures.
yp_validdomain() is called inside yp_open_db() now, so procedures that
call into the database package don't need to use yp_validdomain()
themselves.

- Fix a bogosity in ypproc_maplist_2_svc(): don't summarily initiallize
the result.maps pointer to NULL. This causes yp_maplist_free()
to fail and leaks memory.

- Make ypproc_master_2_svc() copy the string it gets from the database
package into a private static buffer before trying to NUL terminate it.
This is necessary with the DB handle caching: stuffing a NUL into the
data returned by DB package will goof it up internally.

yp_main.c:

- Stuff for DB handle caching: call yp_init_dbs() to clear the
handle array and add call to yp_flush_all() to the SIGHUP
signal handler.

Makefile.yp:

- Reorganize to deal with database caching. yp_mkdb(8) can now be used
to send a YPPROC_CLEAR signal to ypserv(8). Call it after each map
is created to refresh ypserv's cache.

- Add support for mail.alias map.
Contributed by Mike Murphy (mrm@sceard.com).

- Make default location for the netgroups source file be /var/yp/netgroup
instead of /etc/netgroup.

mkaliases:

- New file: script to generate mail.alias map.
Contributed by Mike Murphy (mrm@sceard.com).

Makefile:

- Install Makefile.yp as /var/yp/Makefile.dist and link it to
/var/yp/Makefile only if /var/yp/Makefile doesn't already exist.
Suggested by Peter Wemm.

- Install new mkaliases script in /usr/libexec along with mknetid.

- Use somewhat saner approach to generating rpcgen-dependent files
as suggested by Garrett Wollman.

Import the new, non-GPL ypserv, written by yours truly. Functionally
equivalent to the old ypserv, except that it doesn't support the
-p [port] option to force the server to use a particular port.

The server stubs and yp.h header file are auto-generated from the yp.x
protocol definition file. The auto-generated XDR routines in libc/yp
are also used. The database access code has been broken out into a
seperate module so that other NIS utilities (ypxfr in particular)
can use it.

Note that the old mknetid script is being temporarily moved here; it
will be replaced by an mknetid program which will eventually have
a home under /usr/src/libexec. (The existing script is actually
somewhat broken -- it doesn't handle hosts -- but this isn't a big
deal at this point since the netid.byname map is really only useful
fopr Secure RPC, which we don't have yet.)
