more manageable and convenient referencing by login.conf (login
class database) and (e.g.) login.access.
This is the first of a group of commits which implements the login
class capabilities database.
(There may be a behavior difference between the 2.1 and 2.2/3.0 kernels
in this area, it seemed to work for me but I have a horribly hacked
select() that might have a bug in the handling of this)

The `install' target should only be overridden when the default one would
do something wrong and you're too lazy to fix the default one.
Restore the clamp on the return value from rpc_dtablesize().. Some programs
(eg: ypserv) use this as an indication of how large svc_fdset is in their
hand-rolled svc_run() loops. The svc_fdset table is maintained by the
rpc library explicitly for compatability with such programs. (It uses
a different variable-sized bitmap itself internally)

Note: potential bug here, It looks like there could be a null pointer
dereference depending on what has already been called to initialise some
shared data.
- kill non-FD_SETSIZE code
Obtained from: a diff of FreeBSD vs. OpenBSD/NetBSD rpc code.
Note, there was a nasty bug with our old code here. It would trash the
stack if a fd > 31 was passed in. It was using a "long" as though it
was an "fd_set", ie: it was assuming that a long was 256 bits wide. :-(
This has been lurking here for a while, since the FD_SETSIZE #ifdef's
were first implemented.

RELENG_2_2!
This is part#2 of the previous commit to src/lib/libc/net to contain the
potential damage.
This provides stubs so that binaries linked in 2.2 will run on 3.0
needed, as he discovered when he tried to run vi. :-]
These files used to be stubs which used #ifdef PIC to decide whether to
use the real dlopen() version or the stub version from the src/contrib/tcl
sources. Now, with the our stubs gone, the .PATH directive causes them to
be compiled directly from src/contrib/tcl/{unix,generic}. You might need
to rebuild your depend rules though as they may have stale paths.
Also, this is a generated file. This should not have been edited here.
also add the missing declaration of forkpty() to libutil.h.
Btw., the calling interface for login(3) is crude. Some better
abstraction is needed, perhaps similar to logwtmp(3).
2.2 candidate, but i'll wait for the spelling police first. :)
- the .gz files are no longer used as intermediate files, it's in a pipe
now. (gunzip normally deleted them anyway, but this should not hurt)
- I accidently left a -p arg to install from testing. Bruce says it should
be ${COPY} instead, but almost everything else in the tree uses plain -c
anyway.
- Use "LINKS=" or two identical files are installed sepeately instead of
as links (doh!)
- Use "LIB..." instead of "BIN..." for install permissions. Note that we
still use bsd.prog.mk, not bsd.lib.mk because bsd.lib.mk has problems
(it can't install a library unless it compiles it).
- Define LIBCOMPATDIR in Makefile.inc instead of using BINDIR.

just return errors. This removes the need for awful hacks like that in
our build of libtcl which would get link errors when linked static.
John Polstra once mentioned that this was on his "todo" list.
Note that one can use:
cc -Wl,-Bstatic -o foo foo.o
and get an executable that has it's libraries statically linked, but has
a fully functional runtime linker so the executable can call dlopen() and
have it work. (I've tested this)
- getpwent:
o adjunctbuf should be NUL terminated after copying
o _pw_breakout_yp() needs to know the length of the buffer returned
from YP so it can properly NUL terminate its local buffer.
- getgrent:
o YP buffers should be YPMAXRECORD + 2 bytes long and NUL terminated.
(Previously they were hardcoded to 1024 bytes.)
- getnetgrent:
o YP data should be copied with snprintf(), not sprintf()
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.
- 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.
line length limit anymore - now 500 members or 5000 members are
possible. For security group lines longer than 256K will be count as
an error. 256K should be enough for 65536 users.
Support comments (lines that begin with a #) if compiled with
option -DGROUP_IGNORE_COMMENTS.
Fortunately it seems that all system utilities which use getgrent()
functions are dynamically linked executables. So you need only
rebuild libc.so.3.0 if you want this change. Note: if you have
an old X server which depend on libc.so.2.* you should rebuild
libc.so.2.* too.
Not a 2.2 candidate.
lookup results. Without this, doing multiple host/addr lookups in a
single process yeilds strange results (the buffer is static, and
garbage may be left behind from previous lookups).
I just noticed this in 2.2-BETA. Unless somebody threatens to chop my
hands off with an axe, I'm going to move this to the 2.2-RELENG branch
shortly.
of BIND, we need to tweak some things to that gethostanswer() knows
whether or not we're dealing with an IPv4 or IPv6 address. (This'll
teach me to use a 2.1.0 system for NIS development -- but it's so nice
and stable I just can't being myself to upgrade it. :)
- A major 11th hour, last second, untested commit!
Build some infrastructure to clean up the compat lib distributions, and
also allow them to be installed from the source tree rather than having
to to and get the tarballs from freefall or a CD. Some tweaks to
/etc/make.conf are in the pipeline to enable it.
This came about because it became apparent that we'd have to change the
compat21.tgz tarball to fix the NIS problem with 2.1.x binaries. Since
it's tar..gz.uu, doing this would have caused a huge repository change
and we may as well try and fix it once and for all. Now, adding/removing
libraries should have MUCH less repository impact.

Passing observation: The fixes that pst put in on 1996/09/22 then backed out
look like they should be put in again. If sysinstall is depending on bugs,
then it should be fixed.
_yp_dobind() checks to see if a fork() happens (by checking PIDs) and
invalidates all bindings if it finds itself in a newly created child
process. (This avoids sharing RPC client handles and socket descriptors
with the parent, which would be bad.) Unfortunately, it summarily
calls clnt_destroy() on the handles, which may result in the destruction
of a descriptor that isn't really a socket.
This is fixed by replacing the explicit call to clnt_destroy() with a
call to _yp_unbind(), which deals with potentially hosed socket descriptors
an a safe manner.
This is basically a one-liner. Once I confirm that it fixes Christoph's
problem, I'd like permission to put it in the 2.2-RELENG branch.
Vulnerable: all programs that use setlocale(LC_COLLATE),
setlocale(LC_CTYPE), or setlocale(LC_ALL). The only setuid/setgid
binary i've found for this is w(1).
Should go into 2.2.
I've added an installation from optical disk drive facility.
This enables FreeBSD to be installed from an optical disk, which
may be formatted in "super floppy" style or sliced into MSDOS-FS
and UFS partitions.
Note: ncr.c should be reviewed by Stefan Esser <se@freebsd.org>
and cd.c by Joerg Wunsch <joerg@freebsd.org> before bringing this
into 2.2.

and he said:
The 3rd agrument is new; looks like it was part of the upgrade to
a new BIND with some IPv6 support. The third argument here should be
AF_INET. In order for it to be anything else, I'd have to add new
NIS functions to support IPv6 lookups. I don't even know what those
look like yet.
So there ya go, add AF_INET as the 3rd argument to the call.

copy of insure++, too bad the runtime only works for BSD/OS. :-(
Maybe they'll be so impressed by my initial 15 entry bug report for it
that they'll take the FreeBSD version more seriously. :-) :-)
NIS map which is present on SunOS NIS servers with the SunOS C2 security
hack^Woption installed. I'm convinced that the C2 security option restricts
access to the passwd.adjunct.byname map in the same way that I restrict
access to the master.passwd.{byname,buid} maps (checking for reserved ports),
which means that we should be able to handle passwd.adjunct.byname map
correctly.
If _havemaster() doesn't find a master.passwd.byname map, it will now
test for a passwd.adjunct.byname map before defaulting back to the
standard non-shadowed passwd.{byname,byuid} maps. If _pw_breakout_yp()
sees that the adjunct map was found and the password from the standard
maps starts with ##, it will try to grab the correct password field
from the adjunct map. As with the master.passwd maps, this only happens
if the caller is root, so the shadowing feature is preserved; non-root
users just get back ##username as the encrypted password.
Note that all we do is grab the second field from the passwd.adjunct.byname
entry, which is designated to be the real encrypted password. There are
other auditing fields in the entry but they aren't of much use to us.
Also switched back to using yp_order() to probe for the maps (instead
of yp_first()). The original problem with yp_order() was that it barfed
with NIS+ servers in YP compat mode since they don't support the
YPPROC_ORDER procedure. This condition is handled a bit more gracefully
in yplib now: we can detect the error and just punt on the probing.
Since locale reading code not resistent against stack overflowing or
similar intruder attacks, don't allow PATH_LOCALE env variable action
for s-bit programs (non-standard locale path setting)
strdup() it to prevent unsetenv() or setenv() effects. Check its length to
not allow user to overflow internal locale buffer. Move PATH_LOCALE
handling code into one place.
POSIX: make better stub for LC_MONETARY & LC_NUMERIC, now it check
locale directory existance instead of refusing all non-C non-POSIX
locales. POSIX treats empty locale env variable as unset variable
while our old code treats it as "C" locale, fix it. Implement previous locale
restoring, if locale setting fails. Old code assumes success if some
of LC_ALL subset is successed even other fails, POSIX treats it as
failure with previous locale restoring, fix it.
Remove unneccessary length checking in currentlocale()
Garbage in `eacces' caused the wrong errno to be set for non-EACCES errors.
Garbage in `etxtbsy' caused a semi-random retry strategy for ETXTBSY errors.
Found by: NIST-PCTS. gcc -Wall reported the problem, but -Wall is not
enabled for libc.
FTP error return code because
1) They return NULL, it means that ftpErrno can't be used because
it takes file pointer
2) They don't have FILE-type argument as f.e. ftpGet/ftpPut to use
it for ftpErrno instead.
For that functions I add yet one int* type argument to store
FTP error return code. It is impossible to add some global variable
for that reason, because user can have multiply FTP connections
opened at the same time.
So, interface changed, major number bumped.
Userland changes will follows.
Minor bugfixes, the code:
Forget to close file in few places, when failure occurse
Forget to NULL cached host name, multiply free is possible
