7560bb26ff Finally complete my fix for the behaviour of getpass(3) upon receipt
of signals.  Signals are now properly caught, tty state is being
restored, and the previous sigaction triggered.  Upon receipt of a
sigcont, echo is turned off again.

SIGTSTP causes a buffer flush, the man page mentions this.  (Although
i rather think of it as a feature than a bug.)

This is likely to be my last FreeBSD action for 1995, xearth shows
me that our .au guys must already write 1996. :-)

912e603778 Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches.  The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes.  Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header.  This
hack will do until then.  (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'.  `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.

and it's a little slower on a P5. Also moved the count mask and 'std'

         the fly), and xdr_datum(), which isn't used internally by
         libc, but which as documented as being there in yp_prot.h,
         so what the hell. We now get everything else from yp_xdr.c.

         yp.h instead of those declared in yp_prot.h.

04936d2e08 Change phkmalloc so that the page directory is now floating and allocated
via mmap() up around the shared library area.  Previously the directory
was allocated from space from it's own memory pool.  Because of the way it
was being extended on processes with large malloced data segments (ie: inn)
once the page directory was extended for some reason, it was not possible
to lower the heap size any more to return pages to the OS.
(If my understanding is correct, page directory expansion occurs at 4MB,
12MB, 20MB, 28MB, etc.)  I was seeing INN allocate a large amount of short
term memory, pushing it over the 28MB mark, and once it's transient demands
hit 28MB, it never freed it's pages and swap space again.)

I've been running this in my libc for about a month...

Also, seperate MALLOC_STATS from EXTRA_SANITY..  I found it useful to call
malloc_dump() from within INN from a ctlinnd command to see where the hell
all the memory was going.. :-)  I've left MALLOC_STATS enabled, as it has
no run-time or data storage cost.

0f98415ed4 - Make _do_ypbind() check for /var/run/ypbind.lock and attempt to flock()
it before before trying to establish a binding. If /var/run/ypbind.lock
  doesn't exist, or if it exists and isn't locked, then ypbind isn't
  running, which means NIS is either turned off or hosed.

- Have _yp_check() call yp_unbind() after it sucessfully calls yp_bind()
  to make sure it frees resources correctly. (I don't think there's really
  a memory leak here, but it seems somehow wrong to call yp_bind() without
  making a corresponding call to yp_unbind() afterwards.)

This makes the NIS code behave a little better in cases where libc makes
calls to NIS, but it isn't running correctly (i.e. there's no ypbind).

This cleans up some strange libc behavior that manifests itself if
you have the system domain name set, but aren't actually running NIS.
In this event, the getrpcent(3) code could try to call into NIS and
cause several inexplicable "clnttcp_create error: RPC program not
registered" messages to appear. This happens because _yp_check() checks
if the system domain name is set and, if it is, proceeds to call
yp_bind() to attempt to establish a binding. Since there is no
binding file (remember: ypbind isn't running, so /var/yp/binding
will be empty), _yp_dobind() will attempt to contact ypbind to
prod it into binding the domain. And because ypbind isn't running,
the code generates the 'clnttcp_create' error. Ultimately the
_yp_check() fails and the getrpcent(3) code rolls over to the /etc/rpc
file, but the error messages are annoying, and the code should be
smart enough to forgo the binding attempt when NIS is turned off.

Note that there is only one NIS services map (services.byname) even
though there are getservbyname() and getservbyport() library functions.

3948edc24c Another tweak/speedup pass:
- Fix buffer overflow problem once and for all: do away with the buffer
  copies to 'user' prior to calling _scancaches() and just pass a pointer
  to the buffer returned by yp_match()/yp_first()/yp_next()/whatever.
  (We turn the first ':' to a NUL first so strcmp() works, then change it
  back later. Submitted by Bill Fenner <fenner@parc.xerox.com> and
  tweaked slightly by me.

- Give _pw_breakout_yp() the 'more elegant solution' I promised way back when.
  Eliminate several copies to static buffers and replace them with just
  one copy. (The buffer returned by the NIS functions is at most
  YPMAXRECORD bytes long, so we should only need one static buffer of
  the same length (plus 2 for paranoia's sake).)

- Also in _pw_breakout_yp(): always set pw.pw_passwd to the username
  obtained via NIS regardless of what pw_fields says: usernames cannot
  be overridden so we have no choice but to use the name returned by
  NIS.

- _Again_ in _pw_breakout_yp(): before doing anything else, check that
  the first character of the NIS-returned buffer is not a '+' or '-'.
  If it is, drop the entry. (#define EXTRA_PARANOIA 1 :)

- Probe for the master.passwd.* maps once during __initdb() instead
  of doing it each time _getyppass() or _nextyppass() is called.

- Don't copy the NIS data buffers to static memory in _getyppass()
  and _nextyppass(): this is done in _pw_breakout_yp() now.

- Test against phkmalloc and phkmalloc/2 (TNG!) to make sure we're
  free()ing the yp buffers sanely.

- Put _havemaster(), _getyppass() and nextyppass() prototypes under
  #ifdef YP. (Somehow they ended up on the wrong side of the #endif.)

- Remove unused variable ___yp_only.

eb6c139019 Some NIS bug stomping:
- In some cases, we don't properly resolve _all_ possible group memberships.
  If a user is a member of both local and NIS groups, we sometimes lose some
  of the membership info from NIS. (Reported by: Thorsten Kukuk
  <kukuk@uni-paderborn.de>)

- Make NIS +groupname overrides actually work the way the SunOS group(5)
  man page says they should (make them work for all cases: getgrent(),
  getgrnam() and getgrgid()).

- When not compiled with -DYP, grscan() should ignore entries that
  begin with a '+'. When compiled _with_ -DYP, grscan() should ignore
  +groupname entries that don't refer to real NIS groups.

- Remove redundant redeclaration of fgets(), strsep() and index() inside
  grscan(). We already #include all the right header files for these.

Note: -groupname exclusion as specified in the Sun documentation still
isn't supported. This'll be a 2.2 addition. Right now I just want this
stuff to work.

11e67a9f2e Fix the problem that I aroused with the last commit..
What was happening, is if syslogd was not running, syslog() would do
a strcat("\r\n") on a non-null-terminated buffer, and write it to the console.

This meant that sometimes extra characters could be written to the console
during boot, depending on the stack contents.

This totally avoids the potential problem by using writev() like the rest
of the does, and avoid modifying the buffer after the trouble we've gone to
to carefully protect it.

This is actually a trivial fix, in spite of the long commit message.. :-)
It only appeared during boot and shutdown with syslogd stopped.

7c8e2aa48c Fix security bugs with a "new approach", using stdio's powerful buffer
control hooks.
It is similar to an unrolled multi-part snprintf(), in that a "FILE *" is
attached to a string buffer.  There is also an optimisation for the case
where the syslog format string does not contain %m, which should improve
performance of "informational" logging, like from ftpd.

Fix for PR #510. The original problem was that __ivaliduser() was
failing to grant access to a machine listed in a +@netgroup specified
in /etc/hosts.equiv, even though the host being checked was most
certainly in the +@netgroup.

The /etc/hosts.equiv file in question looked like this:

localhost
+@netgroup

The reason for the failure was had to do with gethostbyaddr(). Inside
the __ivaliduser() routine, we need to do a gethostbyaddr() in order
to get back the actual name of the host we're trying to validate since
we're only passed its IP address. The hostname returned by gethostbyaddr()
is later passed as an argument to innetgr(). The problem is that
__icheckhost() later does a gethostbyname() of its own, which clobbers
the buffer returned by gethostbyaddr().

The fix is just to copy the hostname into a private buffer and use
_that_ as the 'host' argument that gets passed to innetgr().

And here I was crawling all over the innetgr() code thinking the
problem was there. *sigh*

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. :)

Back out the 'help NIS rebind faster' hack. This change used a
connect()/send() pair rather than the original sendto() to allow
RPC to pass ICMP host unreachable and similar errors up to RPC
programs that use UDP. This is not a terrible thing by itself, but it can
cause trouble in environments with multi-homed hosts: if the portmapper
on the multi-homed machine sends a reply with a source address
that's different than the one associated with the connection by
connect(), the kernel will send a port unreachable message and
drop the reply. For the sake of compatibility with everybody else
on the planet, it's best to revert to the old behavior.

bc8e373c9b The ypprot_err() function incorrectly maps YP_NODOM to YPERR_NODOM.
Strange as it sounds, it should map to YPERR_DOMAIN instead.

The YP_NODOM protocol error code is generally returned by ypserv when you
ask it for data from a domain that it doesn't support. By contrast,
the YPERR_NODOM error code means 'local domain name not set.'
Consequently, this incorrect mapping leads to yperr_string() generating
a very confusing error message. YPERR_DOMAIN says 'couldn't
bind to a server which serves this domain' which is much closer
to the truth.

e0ee807b3d Fix for a potential problem reported by a user I bumped into on IRC
last night:

_gr_breakout_yp() doesn't check for badly formatted NIS group entries.
For example, a bogus entry like this:

bootp::user1,user2,user3

will lead to a null pointer dereference and a SEGV (note that the GID
field is missing -- this results in one of the strsep(&result, ":")
returning NULL). The symtpom of this problem is programs dumping
core left and right the moment you add a + entry to /etc/group.
Note that while this is similar to an earlier bug, it's caused by a
different set of circumstances.

The fix is to check for the NULL pointers and have _gr_breakout_yp()
punt and return a failure code if it catches one. This is more or
less the behavior of SunOS: if a bad NIS group entry is encountered,
it's silently ignored. I don't think our standard (non-NIS) group
parsing code behaves the same way. It doesn't crash though, so I'm
citing the 'it ain't broken, don't fix it' rule and leaving it alone.

I'll probably have to add similar checks to _pw_breakout_yp() in
getpwent.c to ward off the same problems. It's rare that bad NIS
map entries like this occur, but we should handle them gracefully
when they do.

dbf973c0c7 Fixes for PR #508 and #509 ('botched 'Bad netgroup' error message' and
'cycle in netgroup check too greedy').

PR #508 is apparently due to an inconsistency in the way the 4.4BSD
netgroup code deals with bad netgroups. When 4.4BSD code encounters
a badly formed netgroup entry (e.g. (somehost,-somedomain), which,
because of the missing comma between the '-' and 'somedomain,' has
only 2 fields instead of 3), it generates an error message and
then bails out without doing any more processing on the netgroup
containing the bad entry. Conversely, every other *NIX in the world
that usees netgroups just tries to parse the entry as best it can
and then silently continues on its way.

The result is that two bad things happen: 1) we ignore other valid entries
within the netgroup containing the bogus entry, which prevents
us from interoperating with other systems that don't behave this way,
and 2) by printing an error to stderr from inside libc, we hose certain
programs, in this case rlogind. In the problem report, Bill Fenner
noted that the 'B' from 'Bad' was missing, and that rlogind exited
immediately after generating the error. The missing 'B' is apparently
not caused by any problem in getnetgrent.c; more likely it's getting
swallowed up by rlogind somehow, and the error message itself causes
rlogind to become confused. I was able to duplicate this problem and
discovered that running a simple test program on my FreeBSD system
resulted in a properly formatted (if confusing) error, whereas triggering
the error by trying to rlogin to the machine yielded the missing 'B'
problem.

Anyway, the fixes for this are as follows:

- The error message has been reformatted so that it prints out more useful
  information (e.g. Bad entry (somehost,-somedomain) in netgroup "foo").
  We check for NULL entries so that we don't print '(null)' anymore too. :)

- Rearranged things in parse_netgrp()  so that we make a best guess at
  what bad entries are supposed to look like and then continue processing
  instead of bailing out.

- Even though the error message has been cleaned up, it's wrapped inside
  a #ifdef DEBUG. This way we match the behavior of other systems. Since we
  now handle the error condition better anyway, this error message becomes
  less important.

PR #507 is another case of inconsistency. The code that handles
duplicate/circular netgroup entries isn't really 'too greedy; -- it's
just too noisy. If you have a netgroup containing duplicate entries,
the code actually does the right thing, but it also generates an error
message. As with the 'Bad netgroup' message, spewing this out from
inside libc can also hose certain programs (like rlogind). Again, no
other system generates an error message in this case.

The only change here is to hide the error message inside an #ifdef DEBUG.
Like the other message, it's largely superfluous since the code handles
the condition correctly.

Note that PR #510 (+@netgroup host matching in /etc/hosts.equiv) is still
being investigated. I haven't been able to duplicate it myself, and I
strongly suspect it to be a configuration problem of some kind. However,
I'm leaving all three PRs open until I get 510 resolved just for the
sake of paranoia.

04adcdacbf Small fix for the following problems:
- If you take the wheel entry out of /etc/group and turn on NIS,
the '+:*::' line is incorrectly flagged as the entry for wheel (the
empty gid section is translated to 0), hence getgrgid() returns '+'
as the name of the group instead of 'wheel.'

- Using just '+:' as the 'turn on NIS' switch in /etc/group makes
getgrgid() dump core because of a null pointer dereference. (Last
time I was in here, I foolishly assumed that fixing the core dump
problems with getgrnam() and getgrent() would fix getgrgid() too.

456ebbf8f5 ypbind.c: Major overhaul.
- Moved to a more client-driven model. We aggressively attempt to keep
the default domain bound (as before) but we give up on non-default
domains if we lose contact with a server and fail to get a response
after one round of broadcasting. This helps drastically reduce the
amount of network bandwitdh that ypbind consumes: if a client references
the secondary domain at some later point, this will prod ypbind into
establishing a new binding anyway, so continuously broadcasting without
need is pointless.

Note that we still actively seek out a binding for our default domain
even if no client program has queried us yet. I'm not exactly sure if
this matches SunOS's behavior or not, but I decided to do it this way
since we can get into all sorts of trouble if our default domain comes
unbound. Even so, we're still much quieter than we used to be.

- Removed a bunch of no-longer pertinent comments and a couple of
chunks of #ifdef 0'ed code that no longer fit in to the new layout.

- Theo deRaadt must have become frustrated with the callback mechanism
in clnt_broadcast(), because he shamelessly stole the clnt_broadcast()
code right out of the RPC library and hacked it up to suit his needs.
(Comments and all! :)

I can understand why: clnt_broadcast() blocks while awaiting replies.
Changing this behavior requires surgery. However, you can work around
this: fork the broadcast into a child process and relay the results
back to the parent via a pipe. (Careful obervation has shown that the
SunOS ypbind forks children for broadcasting too, though I can only
guess what sort of interprocess communication it uses. pipe() seems to
do the job well enough.)

This may seem like the long way around, but it's not really that
hard to implement, and I'd prefer to use documented RPC library functions
wherever possible. We're careful to limit the number of simultaneous
broadcasters to avoid swamping the system (the current limit is 5).
Each clnt_broadcast() call only sends out a small number of packets
at increasing intervals. We're also careful not to spawn more than one
bradcaster for a given domain.

- Used clntudp_bufcreate() and clnt_call() to implement a ping()
function for directly querying a particular server so that we can
check if it's still alive. This lets me completely remove the old
bradcasting code and use actual RPC library calls instead, at the
cost of more than a few handfulls of torn-out hair. (Make no mistake
folks: I *HATE* RPC.) Currently, the ping interval is one minute.

- Fixed another potential 'nfds too big for select()' bug: use
_rpc_dtablesize() instead of getdtablesize().

- Quieted gcc -Wall a bit.

- Probably a bunch of other stuff that I've forgotten.

ypbind.8:

- Updated man page to reflect modifications.

ypwhich.c:

- Small mind-o fix from last time: decode error results from
ypbind correctly (*groan*)

yplib.c:

- same as above

- Change behavior of _yp_dobind() a little: if we get back a 'Domain
not bound' error for a given domain, retry a few times before giving
up and passing the error back to the caller. We have to sleep for a
few seconds between tries since the 'Domain not bound' error comes
back immediately (by repeatedly looping, we end up pounding on ypbind).
We retry at most 20 times at 5 second intervals. This gives us a full
minute to get a response. This seems to deviate a bit from SunOS
behavior -- it appears to wait forever -- but I don't like the idea
of perpetually hanging inside a library call.

Note that this should fix the problems some people have with bindings
not being established fast enough at boot time; sometimes amd is started
in /etc/rc after ypbind has run but before it gets a binding set up. The
automounter gets annoyed at this and tends to exit. By pausing ther YP
calls until a binding is ready, we avoid this situation.

- Another _yp_dobind() change: if we determine that our binding files
are unlocked or nonexistent, jump directly to code that pokes ypbind
into restablishing the binding. Again, if it fails, we'll time out
eventually and return.

f067dfeabc Fix behavior of YP library routines in environments with multiple domains,
where one or more of the non-default domains are not yet bound.

If we make a YP request for a domain other than the default domain,
and there is no binding for the new domain yet, _yp_dobind() sees
that the /var/yp/binding/DOMAIN.VERS file for the unbound domain is
not locked (by ypbind) and from this it concludes that the NIS system
is dead, so it gives up.

This behavior has been changed: before giving up in this case, we now
make a second check to see if the binding file for the *default* domain
is also not locked. Only if the default domain binding file is also
unlocked to we now assume that ypbind has bought the farm and bail out.
(Note: this assumes that the user hasn't changed the default domain
while ypbind is running.)

With this change, _do_ypbind() is allowed to proceed into the next
section of code wherein it prods ypbind into establishing a binding
for the new domain. This first call times out after ten seconds,
after which it should retry and succeed. From then on, the binding
for the second domain should be handled normally.

ef8f52ad53 'Fix' for esoteric misfeature discovered while searching for another bug:
select() returns EINVAL if you try to feed it a value of FD_SETSIZE greater
that 256. You can apparently adjust this by specifying a larger value of
FD_SETSIZE when configuring your kernel. However, if you set the maximum
number of open file descriptors per process to some value greater than
the FD_SETSIZE value that select() expects, many selects() within the RPC
library code will be botched because _rpc_dtablesize() will return
invalid numbers. This is to say that it will return the upper descriptor
table size limit which can be much higher than 256. Unless select() is
prepared to expect this 'unusually' high value, it will fail. (A good
example of this can be seen with NIS enabled: if you type 'unlimit' at
the shell prompt and then run any command that does NIS calls, you'll
be bombarded with errors from clnttcp_create().)

A temporary fix for this is to clamp the value returned by _rpc_dtablesize()
at FD_SETSIZE (as defined in <sys/types.h> (256)). I suppose the Right
Thing would be to provide some mechanism for select() to dynamically
adjust itself to handle FD_SETSIZE values larger than 256, but it's a
bit late in the game for that. Hopefully 256 file descriptors will be enough
to keep RPC happy for now.

Have you been plagued by long waits when your NIS server is rebooted?
READ ON!

Sun has a patch, but the README says:

********************* WARNING ******************************

  This is a new version of ypbind that never uses the NIS
  binding file to cache the servers binding. This will have
  the effect of fixing the current symptom. However, it might
  degrade the overall performance of the system when the
  server is available. This is most likely to happen on an
  overloaded server, which will cause the network to produce
  a broadcast storm.

*************************************************************

Therefor, I have produced another fix.

o What goes wrong.

When the NIS server is rebooted, ypserv will obtain different ports
to listen for RPC requests. All clients will continue to use the old
binding they obtained earlier. The NIS server will send ICMP dst unreachable
messages for the RPC requests that arrive at the old port. These ICMPs
are dropped on the floor and the client code will continue sending the
requests until the timer has expired. The small fix at the end of this
message will pick up these ICMP messages and deliver them to the RPC layer.

o Before and after.

I've tested this on some machines and this is the result:

	(kill and restart ypserv on the server)

original% time ypmatch user passwd
user:....
0.040u 0.090s 2:35.64 0.0% 0+126k 0+0io 0pf+0w (155 seconds elapsed time)

fixedhost% time ypmatch user passwd
user:....
0.050u 0.050s 0:10.20 0.9% 0+136k 0+0io 0pf+0w (10 seconds elapsed time)

Rebinding is almost instantaneous.

o Other benefits.
	RPC calls that use UDP as transport will no longer time out but
	will abort much sooner. (E.g., the remote host is unreachable or
	111/udp is filtered by an intermediate router)

d34ef3d62b As per Justin T. Gibbs's request, agument the +@netgroup/-@netgroup
remapping mechanism in the following manner: if given an entry +@foo
and there is no netgroup named 'foo,' try searching for a regular
user group called 'foo' and build the cache using the members of
group 'foo' instead. If both a netgroup 'foo' and a user group 'foo'
exist, the 'foo' netgroup takes precedence, since we're primarily
interested in netgroup matching anyway.

This allows access control schemes based on ordinary user groups
(which are also available via NIS) rather than netgroups, since
netgroups on some systems are limited in really brain-damaged ways.

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

d26be6f09d Obtained from: 1.1.5. Originally by jtc. Cosmetically changed for this
commit by bde.

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).

old-cvs log:
revision 1.4
date: 1993/11/04 19:38:22;  author: jtc;  state: Exp;  lines: +33 -20
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.

be7f0d04fe On snap 950210, format %s (print seconds from the epoch) is missing
from the code in strftime.c . This affects both the library code
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.

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
   is "/".  buf[0] and buf[2] are clobbered.

(I modified Bruce's original patch to return the proper error code
[ERANGE] in the case of #2, but otherwise... -DG)

This program demonstrates the bug:

---
#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include <unistd.h>

int main(void)
{
    char buf[5];
    int errors;

    errors = 0;
    if (chdir("/tmp") != 0) {
        perror("chdir");
        abort();
    }
    if (getcwd(buf, 5) == NULL) {
        perror("oops, getcwd failed for buffer size = size required");
        ++errors;
    }
    if (chdir("/") != 0) {
        perror("chdir");
        abort();
    }
    buf[0] = 0;
    buf[2] = 1;
    if (getcwd(buf + 1, 1) != NULL) {
        fprintf(stderr,
                "oops, getcwd succeeded for buffer size = one too small\n");
        ++errors;
    }
    if (buf[0] != 0) {
        fprintf(stderr,
                "oops, getcwd scribbled on memory before start of buffer\n");
        ++errors;
    }
    if (buf[2] != 1) {
