case of a `+' entry in the password file but YP not running, which should
never happen but is easy enough to check for so we'll apply some
prophylaxis.)

input forms. It has the following simple fields:
Text fields: Just titles, labels etc.
Input fields: An editable text field that may or may not have an
initial default value.
Labelled input field: This is an input field that has an initial
informative entry in it but it vanishes when you start editing the
field.
Toggle fields: These are fields with a pre-defined list of options
which you cycle through using the space bar.
Action fields: These are button type fields that call functions when
they are selected.

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) {
fprintf(stderr,
"oops, getcwd scribbled on memory after end of buffer\n");
++errors;
}
exit(errors == 0 ? 0 : 1);

pointer returned by realloc(). All callers free the pointer if the

nuke similar but non-broken caching in execvp(). malloc() should be
efficient enough.

Change the reference for the libtermcap libtermlib link from SHLIBDIR

This should go into the beta as the code which it calls in the kernel is

input fields. It reads a template file passed to init_forms(char *)

This effectively changes the non-DES password algoritm.
If you have the "securedist" installed you will have no problems with this.
(Though you might want to consider using this password-encryption instead
of the DES-based if your system is likely to be hacked)
If you are running a -current system without the "securedist" installed:
YOU WILL NEED TO CHANGE ALL PASSWORDS !! There is no backwards mode.
Suggested procedure is:
Update your sources
cd /usr/src/lib/libcrypt
make clean
make all
make install
passwd root
<set roots new password>
change password for any other users on the system.
This algorithm is expected to be much better than the traditional DES-
based algorithm. It uses the MD5 algorithm at what it is best at, as
opposed to the DES algorithm at something it isn't good at at all. The
algorithm is designed such that it should very hard to shortcut the
calculations needed to build a dictionary, and to make partial knowledge
(Hmm, his password starts with a 'P'...) useless. Of course if somebody
breaks the MD5 algorithm this looses too.
The salt is 48 bits (8 char @ base64).
The encrypted password is 128 bits.
And I am positively delighted to say that it takes 34 msec to crypt() a
password on a Pentium/60Mhz, so building a dictionary is not really an
option for hackers at the moment.
Given the right circumstances, a call to kvm_open can result in a core
dump.
The diff belows fixes this (note that this change is already in the
NetBSD code). Could somebody apply this?

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().]

I know that many of these entries are bogus and need to be revisited,
but let's get the tree working again for now and then do a pass through
looking at all the __FreeBSD__ entries, shall we?
While trying to figure out why rlogind wasn't working right for root,
I noticed that man wouldn't come back with a man page for iruserok, but
it would for ruserok. Checking the lib/net directory's Makefile.inc
file shows that the link to the rcmd man page just isn't getting
created.
>How-To-Repeat:
Do a 'man iruserok' and notihing will come back, where a 'man ruserok'
will.

You MUST pwd_mkdb /etc/master.passwd before attempting to use the new

wrong, but the actual behavior is undefined. YOU HAVE BEEN WARNED.)
The database format is, however, backwards-compatible, so old executables

(void) setlocale(LC_ALL, "");
It will be easiest way now to make national chars available
for all ctype-oriented programs at once by simple:
setenv LANG Your_National_Charset
Default case (without "LANG" environment
variable) will be fully ANSI compatible (got "C" locale).
If "LANG" variable present, extention becomes active.
Effect of this extention is great: in one time all ctype
oriented programs can accept/print national characters
without any touching source/binary code, it is big win, IMHO.
This method is fully compatible with ISO8859-* and russian koi8-r
too (in general -- with all 8-bit character sets). I think
it is very useful.
I got this idea from Xenix locale implementation.
This extention is even never compiled in, unless you set
setenv STARTUP_LOCALE
before rebuilding crt0.c or corresponding variable in /etc/make.conf
