that everyone else does: you can now use +host/-host, +user,-user and
+@netgroup/-@netgroup in /etc/hosts.equiv, /.rhosts, /etc/hosts.lpd and
~/.rhosts. Previously, __ivaliduser would only do host/user matches,
which was lame. This affects all the r-commands, lpd, and any other
program/service that uses ruserok().
An example of the usefullness of this feature would be a hosts.equiv
file that looks like this:
+@equiv-hosts
Since the netgroup database can now be accessed via NIS, this lets you
set up client machines once and then never have to worry about them
again: all hosts.equiv changes can now be done through NIS. Once I
finish with getpwent.c, we'll be able to do similar wacky things
with login authentication too. (Our password field substitution
will finally be on par with everyone else's, and I'll finally be
able to fully integrate my FreeBSD machine into my network without
having to worry about the grad students sneaking into it when I'm
not looking. :)
Danger Will Robinson! I tested this thing every which way I could, but
Murphy's Law applies! If anybody spots a potential security problem with
the way my matching algorithm works, tell me immediately! I don't want
crackers snickering and calling me names behind my back. :)

changing
if (parse_netgrp(spos))
return(1);
to
if (parse_netgrp(spos))
continue;
inside parse_netgrp(). (Lucky for me I happen to have a fairly complex
'live' netgroup database to test this stuff with.)
as tn3270 can replace _putchar(0 with their own routine and still keep
using the __cputchar() routine used by all of the other curses routines.

This is a hack, the interface should be changed to use off_t's
everywhere around, but this will require to update all the programs
that happen to use libkvm.
- Added support for reading netgroups from NIS/YP in addition to the
local /etc/netgroups file. (Note that SunOS and many other systems only
support reading netgroups via NIS, which is a bit odd.)
- Fix Evil Null Pointer Dereferences From Hell (tm) that caused
parse_netgrp() to SEGV when expanding netgroups that include
references to other netgroups. Funny how nobody else noticed this.
This is the first step in implimenting +@netgroup substitution in
getpwent.c and any other places that could use it and don't already
support it (which is probably everywhere).
by heading off possible null pointer dereferences in grscan(). Also
change getgrnam() slightly to properly handle the change: if grscan()
returns an rval of 1 and leaves a '+' in the gr_name field and YP is
enabled, poll the YP group.byname map before giving up. This should
insure that we make every effort to find a match in the local and
YP group databases before bailing out.

Today I discovered that rebuilding /usr/include completely from scratch
doesn't work, because the libss Makefile tries to install headers into
/usr/include/ss, which 'make includes' does not create. The result is that
the libss Makefile plants the header files in /usr/include as individual
files called 'ss,' with the second one overwriting the first, and the
third one overwriting the second. So instead of a directory called
/usr/include/ss, you end up with just one file called /usr/include/ss with
only the last header file in it. Check out /usr/include/ss on freefall
and you'll see what I mean.
I've modified the beforeinstall target in the libss Makefile to check
for the presence of the ${DESTDIR}/usr/include/lbss directory and to
create it if it isn't already there. Hopefully I did it right.

Fix bugs in floating point formatting. The 4.4lite version is similar
to revision 1.3 in old-cvs and is missing all of jtc's fixes in revision
1.4 in old-cvs. Revision 1.2 in ncvs fixed one of the old bugs but
introduced at least one new one (for %.0e).

revision 1.4

My work from NetBSD to make printf() & friends ANSI C compliant.
Fixes several bugs in floating point formatting:
1. Trailing zeros were being stripped with %e format.
2. %g/%G formats incorrect.
3. Lots of other nits.
the copy built from here was overwritten by the other copy and the other

and all the commands using it (e.g. date +%s).
Note that %s is not required by ANSI, but we've already got it in 1.1.5.1.

Should have same functionality as old libforms but with new mechanism.
Lots of new features that use the new mechanism are still to be added.
Since functions will come and go from libcompat as they are deprecated
it makes no sense to build a shared library out of it as it will change.
Based on freedback from Terry and Jonas on the mailing lists.

Now this case is dealt with as before ...
