are currently implemented:
YPOLDPROC_NULL
YPOLDPROC_DOMAIN
YPOLDPROC_DOMAIN_NONACK
YPOLDPROC_FIRST
YPOLDPROC_NEXT
YPOLDPROC_MATCH
YPOLDPROC_POLL
These are all implemented as wrappers around their v2 counterparts.
The YPOLDPROC_PUSH, PULL and GET procedures are not implemented since
a) I couldn't figure out exactly what to have them do, and b) I
suspect they're used for doing map transfers between master and
slave servers, which we already do using the v2 protocol anyway.
This means we can server NIS v1 clients but can't be a master or
slave with NIS v1-only servers. I think I'll get over it. :)
The -k (sunos_4_kludge) flag and associated code has been removed
since it is no longer needed.
Also tweaked yp_access() to handle both sets of procedures and
updated the man page.
This solves the problem of being unable to use shared libraries with dots
in their names before the ".so.<version>" code.
This should be brought into -stable.
There are more changes from Paul that look like they should be included,
but they change the format of the hints file, so I'm not going to bring them
in now (but we should in the future).

prevent it from conflicting with other drivers (like the aic7xxx driver).
Most of the work was in spliting out common portions of the driver and
making them generic enough to be called from the eisaconf probe.

configuration mode.
aha1742.c aic7770.c bt74x.c:
Only call eisa_registerdev after the probe is successfully.
eisaconf.c:
Increase kdc->kdc_datalen during the eisa_reg* functions instead of
in the eisa_add* functions since eisa_registerdev has already been
called and we have a kdc to manipulate.
also controlled by /var/yp/securenets).
Add -u flag to turn off the privileged port check done by yp_access();
some commercial systems (IRIX, Solaris 2.x, HP-UX, and probably others)
don't use a reserved port for submitting yppasswd updates. If we always
enforce the check, these client systems will be unable to submit updates
to us.
Document securenets support and -u flag in man page.
Like ypserv, you can compile rpc.yppasswdd to use the tcpwrapper package
instead of securenets if you want to.
in the same was as the SunOS ypserv (same format, described in ypserv man
page). If the user wants tcpwrapper style access control, they can
recompile ypserv to use that instead. This way we get securenets without
having to ship libwrap.a and tcpd.h with core FreeBSD distribution.
If /var/yp/securenets doesn't exist, ypserv allows all connections.
the statically compiled PS_STRINGS and USRSTACK variables. This prevents
programs using setproctitle from coredumping if the kernel VM is increased,

is <sys/unistd.h>, with the prototype in <unistd.h>. sys/unistd.h
is visible to the kernel compile, and is #included by unistd.h.
Also, I missed a reference to a static int in the midst of my other diffs.
kern_fork.c: add the tiny bit of code for rfork operation.
kern/sysv_*: shmfork() takes one less arg, it was never used.
sys/shm.h: drop "isvfork" arg from shmfork() prototype
sys/param.h: declare rfork args.. (this is where OpenBSD put it..)
sys/filedesc.h: protos for fdshare/fdcopy.
vm/vm_mmap.c: add minherit code, add rounding to mmap() type args where
it makes sense.
vm/*: drop unused isvfork arg.
Note: this rfork() implementation copies the address space mappings,
it does not connect the mappings together. ie: once the two processes
have split, the pages may be shared, but the address space is not. If one
does a mmap() etc, it does not appear in the other. This makes it not
useful for pthreads, but it is useful in it's own right for having
light-weight threads in a static shared address space.

In passwd(1):
- Gut most of yp_passwd.c and leave only a few things that aren't common
to pw_yp.c.
- Add support for -d and -h flags to select domains and NIS server hosts
to use when updating NIS passwords. This allows passwd(1) to be used
for changing NIS passwords from machines that aren't configured as
NIS clients. (This is mostly to allow passwd(1) to work on NIS master
servers that aren't configured as clients -- an NIS server need not
necessarily be configured as a client itself.)
NOTE: Realize that having the ability to specify a domain and hostname
lets you use passwd(1) (and chpass(1) too) to submit update requests
to yppasswd daemons running on remote servers in remote domains which
you may not even be bound to. For example, my machine at home is not
an NIS client of the servers on the network that I manage, yet I can
easily change my password at work using my FreeBSD box at home by doing:
'passwd -d work.net.domain -h any.nis.server.on.my.net wpaul'. (Yes,
I do use securenets at work; temporarily modified my securenets file
to give my home system access.) Some people may not be too thrilled
with this idea. Those who don't like this feature can recompile passwd(1)
and chpass(1) with -DPARANOID to restrict the use of these flags to
the superuser.
(Oh, I should be adding proper securenets support to ypserv(8) and
rpc.yppasswdd(8) over the weekend.)
- Merge in changes to allow root on the NIS master server to bypass
authentication and change any user's NIS password. (The super-user
on the NIS master already has privileges to do this, but doing it
through passwd(1) is much easier than updating the maps by hand.)
Note that passwd(1) communicates with rpc.yppasswdd(8) via a UNIX
domain socket instead of via standard RPC/IP in this case.
- Update man page.
In chpass(1):
- Fix pw_yp.c to work properly in environments where NIS client
services aren't available.
- Use realloc() instead of malloc() in copy_yp_pass() and copy_local_pass().
- Fix silly bug in copy_yp_pass(); some of the members of the passwd
structure weren't being filled in correctly. (This went unnoticed
for a while since the old yppasswdd didn't allow changes to the
fields that were being botched.)
- chpass(1) now also allows the superuser on the NIS master server to
make unrestricted changes to any user's NIS password information.
- Use UNIX domain comm channel to rpc.yppasswdd(8) when run by the
superuser on the NIS master. This allows several new things:
o superuser can update an entire master.passwd.{byname,byuid} entry
o superuser can update records in arbitrary domains using -d flag to
select a domain (before you could only change the default domain)
o superuser can _add_ records to the NIS master.passwd maps, provided
rpc.yppasswdd(8) has been started with the -a flag (to do this,
the superuser must force NIS operation by specifying the -y flag
to chpass(1) along with -a, i.e. 'chpass -y -a 'foo:::::::::')
- Back out the 'chpass -a <new password entry> breaks with NIS' fix
from the last revision and fix it properly this time. The previous
revision fixed the immediate problem but broke NIS operation in
some cases.
- In edit.c, be a little more reasonable about deciding when to
prevent the shell field from being changed.
Submitted by Charles Owens <owensc@enc.edu>, who said:
"I made a minor (one-line) modification to chpass, with regards
to whether or not it allows the changing of shells. In the 2.0.5 code,
field changing follows the settings specified in the "list" structure
defined in table.c . For the shell, though, this is ignored. A quick
look in edit.c showed me why, but I don't understand why it was written as
such. The logic was
if shell is standard shell, allow changing
I changed it to
if shell changing is allowed (per table.c) and it is a standard shell
OR if uid=0, then allow changing."
Makes sense to me.
- Update man page.
Close the ip-fragment hole.
Waste less memory.
Rewrite to contemporary more readable style.
Kill separate IPACCT facility, use "accept" rules in IPFIREWALL.
Filter incoming >and< outgoing packets.
Replace "policy" by sticky "deny all" rule.
Rules have numbers used for ordering and deletion.
Remove "rerorder" code entirely.
Count packet & bytecount matches for rules.
Code in -current & -stable is now the same.
explicit that it is global to the entire "session", and that setsid() or
daemon() are need to have been called at some point.
The most notable offender of setlogin() misuse is XFree86's xdm.
