62a771700f Don't let setnetgrent() operate on a null or empty group name: it can
tickle a bug in ypserv and make a serious mess of things.

353fefe325 Very important sanity checks: today I clobbered all four NIS servers on
my network because setnetgrent() was trying to do a lookup on group "".
It seems that an attempt to do a yp_match() (and possible yp_next())
on a null or empty key causes Sun's ypserv in SunOS 4.1.3 to exit
suddenly (and without warning). Our ypserv behaves badly in this
situation too, thoush it doesn't appear to crash. In any event, getpwent,
getnetgrent and yp_match() and yp_next() are now extra careful not to
accidentally pass on null or empty arguments.

Also made a small change to getpwent.c to allow +::::::::: wildcarding,
which I had disabled previously.

- In /usr/src/lib/libc/yp/yplib.c, function yp_first when clnt_call
fails with (r != RPC_SUCCESS) ysd->dom_vers should be set to 0! This
ensures that /var/yp/bindings/dom.vers will be read again on retry.
What happens now is that when our server is down and someone tries to
use yp they will continue to try until kingdom come. So:
        if(r != RPC_SUCCESS) {
                clnt_perror(ysd->dom_client, "yp_first: clnt_call");
                ysd->dom_vers = -1;
                               ^^^^ change to 0

8538335f21 At last! Modified __ivaliduser() to do the same kind of user/host validation
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. :)

e80307946b Whoops: expanding netgroups that reference multiple netgroups doesn't
work because parse_netgrp() doesn't recurse properly. Fixed by
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.)

409495f6c7 Two major changes:
- 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).

89047c9c7c Fix 'putting +: in /etc/group causes many programs to dump core' bug
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.

a393cc06f5 Fixed a rather serious bug that presents itself when FreeBSD is configured
as an NIS client. The pw_breakout_yp routines that are used to populate the
_pw_passwd structire only do anything if the bits in the pw_fields member
_pw_passwd are cleared. Unfortunately, we can get into a state where
pw_fields has garbage in it right before the YP lookup functions are
called, which causes the breakout functions to screw up in a big way.
Here's how to duplicate the problem:

- Configure FreeBSD as an NIS client
- Log in as a user who's password database records reside only in
  the NIS passwd maps.
- Type ps -aux

Result: your processes appear to be owned by 'root' or 'deamon.'
/bin/ls can exhibit the same problem.

The reason this happens:

- When ps(1) needs to match a username to a UID, it calls getpwuid().

- root is in the local password file, so getpwuid() calls  __hashpw()
  and __hashpw() populates the _pw_passwd struct, including the pw_fields
  member. This happens before NIS lookups take place because, by coincidence,
  ps(1) tends to display processes owned by root before it happens upon
  a proccess owned by you.

- When your UID comes up, __hashpw() fails to find your entry in the
  local password database, so it bails out, BUT THE BITS IN THE pw_fields
  STRUCTURE OF _pw_passwd ARE NEVER CLEARED AND STILL CONTAIN INFORMATION
  FROM THE PREVIOUS CALL TO __hash_pw()!!

- If we have NIS enabled, the NIS lookup functions are called.

- The pw_breakout_yp routines see that the pw_fields bits are set and
  decline to place the data retrieved from the NIS passwd maps into the
  _pw_passwd structure.

- getpwuid() returns the results of the last __hashpw() lookup instead
  of the valid NIS data.

- Hijinxs ensue when user_from_uid() caches this bogus information and
  starts handing out the wrong usernames.

AAAARRRRRRRRRGGGGGGHHHHHHHHHH!!!

*Please* don't tell me I'm the only person to have noticed this.

Fixed by having __hashpw() check the state of pw_fields just before
bailing out on a failed lookup and clearing away any leftover garbage.
What a fun way to spend an afternoon.

d0ef66889a Some changes for YP password map handling:
- FreeBSD's NIS server can supply a master.passwd map, which has
  more fields in it than a standard passwd map, so we need a
  _master_pw_breakout() fuction.

- When doing passwd map lookups, look for master.passwd.* by attempting
  a _yp_first() on master.passwd.byname. If it exists, we're being served
  by a FreeBSD NIS server and we should use this map.

- If we aren't the superuser, retrieve only the standard passwd maps.
  If we're being served by a FreeBSD system, then the passwd map has
  no passwords in it, and it won't serve us the master.passwd map unless
  we're superuser anyway.

There's a small speed hit for the superuser inherent in the check for
the master.passwd map, but this lets us dynamically decide what to do
rather than rely on a non-standard config file somewhere. Since all
of this is bypassed for normal users, they shouldn't notice the
difference.

getcwd() has two off-by-one bugs in FreeBSD-2.0:

1. getcwd(buf, size) fails when the size is just large enough.
2. getcwd(buf + 1, 1) incorrectly succeeds when the current directory

From: Chris Torek <torek@bsdi.com>
Here is a semi-official patch (apply to /usr/src/lib/libc/stdio/fseek.c,
rebuild libc, install).  The current code fails when the seek:

  - is optimized, and
  - is to just past the end of the block currently in the buffer, and
  - is followed by another seek with no intervening read operation, and
  - the destination of subsequent seek is within the block left in the
    buffer (seeking to the beginning of a block does not force a read,
    so the buffer still contains the previous block)

so it is indeed rather obscure.

I may have a different `final' fix, as this one `loses' the buffer
contents on a seek that goes just past the end of the current block.

[Footnote: seeks are optimized only on read-only opens of regular
files that are buffered by the file's optimal I/O size.  This is
what you get with fopen(path, "r") and no call to setvbuf().]

9ae159169a Make it easier for programs to figure out what revision of FreeBSD they
are running under.  Here's how to bootstrap (order is important):

1) Re-compile gcc (just the driver is all you need).
2) Re-compile libc.
3) Re-compile your kernel.  Reboot.
4) cd /usr/src/include; make install

You can now detect the compilation environment with the following code:

#if !defined(__FreeBSD__)
#define __FreeBSD_version 199401
#elif __FreeBSD__ == 1
#define __FreeBSD_version 199405
#else
#include <osreldate.h>
#endif

You can determine the run-time environment by calling the new C library
function getosreldate(), or by examining the MIB variable kern.osreldate.

For the time being, the release date is defined as 199409, which we have
already established as our target.
