7e546392b5 Revert $FreeBSD$ to $Id$ 1997-02-22 15:12:41 +00:00

1130b656e5 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.

3951b8e32c Small yet significant tweaks/cleanups:
- getservent:
  o put _yp_check() proto under #ifdef YP where it belongs
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- gethostbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long

- getnetbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- ether_addr:
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying (in this case it's BUFSIZ + 2 bytes,
    but it happens that BUFSIZ == YPMAXRECORD.

- gethostbydns:
  o nuke stray 'return(NULL)' in __dns_getanswer() (harmless but looks silly)

These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.

13629194a5 Get struct ether_addr directly from <net/ethernet.h> rather than pulling
in lots of unrelated junk from <net/if.h> and <net/if_ether.h>.  These
functions still aren't prototyped anywhere (but should be in
<net/ethernet.h>---got that, Bill?).

2696fe9c84 Remove more instances of passing arrays by address when they should
have simply been passed as arrays.  In some cases, casts had even
been added to remove the warnings generated by such misuse!  Aieee!

6daf17201b gethostbynis.c:
- Fix problem described in PR #1079: _gethostbynisaddr() doesn't
  work. Make it accept the same arguments as all the other
  gethostby*addr() functions and properly convert the supplied IP
  address into a text string so that yp_match() can find it in the
  hosts.byaddr map.

- Also fix potential memory leak: copy the results of yp_match() to
  a static buffer and free the result (yp_match() returns dynamically
  allocated memory).

ether_addr.c:

- Since I was in the neighborhood, fix ether_ntohost() and
  ether_hostton() so that they don't bogusly for a free(result)
  when yp_match() fails.

1e890b056a Just when you thought it was safe...
- getnetgrent.c: address some NIS compatibility problems. We really need
to use the netgroup.byuser and netgroup.byhost maps to speed up innetgr()
when using NIS. Also, change the NIS interaction in the following way:

If /etc/netgroup does not exist or is empty (or contains only the
NIS '+' token), we now use NIS exclusively. This lets us use the
'reverse netgroup' maps and is more or less the behavior of other
platforms.

If /etc/netgroup exists and contains local netgroup data (but no '+').
we use only lthe local stuff and ignore NIS.

If /etc/netgroup exists and contains both local data and the '+',
we use the local data nd the netgroup map as a single combined
database (which, unfortunately, can be slow when the netgroup
database is large). This is what we have been doing up until now.

Head off a potential NULL pointer dereference in the old innetgr()
matching code.

Also fix the way the NIS netgroup map is incorporated into things:
adding the '+' is supposed to make it seem as though the netgroup
database is 'inserted' wherever the '+' is placed. We didn't quite
do it that way before.

(The NetBSD people apparently use a real, honest-to-gosh, netgroup.db
database that works just like the password database. This is
actually a neat idea since netgroups is the sort of thing that
can really benefit from having multi-key search capability,
particularly since reverse lookups require more than a trivial
amount of processing. Should we do something like this too?)

- netgroup.5: document all this stuff.

- rcmd.c: some sleuthing with some test programs linked with my own
version of innetgr() has revealed that SunOS always passes the NIS
domain name to innetgr() in the 'domain' argument. We might as well
do the same (if YP is defined).

- ether_addr.c: also fix the NIS interaction so that placing the
'+' token in the /etc/ethers file makes it seem like the NIS
ethers data is 'inserted' at that point. (Chances are nobody will
notice the effect of this change, which is just te way I like it. :)

7680d1b004 Add ether_addr functions to libc. This seems to be the logical place
to put them. A man page is in the works.
