df57947f08 spdx: initial adoption of licensing ID tags.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Initially, only tag files that use BSD 4-Clause "Original" license.

612956f67c Remove unused includes. Make it WARNS=6 friendly. Concerning bin/2442, make
a new function dup_shell() to replace ok_shell() and make it unconditionnally
strdup() its result to make the caller's code simplier. Change ok_shell() to
just return an integer value suitable for tests (it was used mainly for that
purpose). Do not use strdup() in the caller's code but rely on dup_shell()
that will do the job for us.

8c44e77923 It was possible for an unprivileged user to tie up the password
information (no one else can vipw(8), chpass(1), or even passwd(1)),
either on purpose or by accident, until an administrator manually
intervened. Instead, do not lock the master.passwd file while a user
is editing his information. But once we go to write the new
information, check that the modified user's information has not
changed in the password database since we started. Abort the changes
if it has.

Add a $FreeBSD$ to pw_copy.h.

248aee623c Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.

366982a550 Add new option to chpass: -e "expire" ; change the account expire time
from a script as if it was done in the interactive editor.

When reassembling the gecos string, trim any excess trailing commas, they
look ugly in the passwd file. :-)

Have a simple Makefile tweak to prevent mortal users from changing their
fullname.  As ISP's we have seem some real bizzare stuff here..

When decoding the change/expire string, allow the month number as a
synonym for the name of the month.. (ie: 1 as well as Jan or January)
Note that using numbers means there's a chance that you can get bitten
if you're not used to the American DD-MM-YY order.

79a1b8d9e2 Implement incremental passwd database updates. This is done by ading a '-u'
option to pwd_mkdb and adding this option to utilities invoking it.
Further, the filling of both the secure and insecure databases has been
merged into one loop giving also a performance improvemnet.
Note that I did *not* change the adduser command. I don't read perl
(it is a write only language anyway).
The change will drastically improve performance for passwd and
friends with large passwd files. Vipw's performance won't change.
In order to do that some kind of diff should be made between the
old and new master.passwd and depending the amount of changes, an
incremental or complete update of the databases should be agreed
upon.

c2dfe9fe01 Merge in changes to support the new rpc.yppasswdd(8) and fix a few bugs.
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.

9219423651 Make use_yp() smarter about figuring out whether a user is local or
NIS (or both, or neither). Also add support for -l and -y flags to
force behavior to local or NIS. use_yp() also goes out of its way to
retrieve the correct password database information (local or NIS)
depending on what the situation since getpwent() & co. can't
necessarily be trusted in some cases.

Also document new flags in man page.

367157222f Take the ypchfn/ypchsh stuff that was removed from passwd
and graft it into chpass.

Chpass can now tell when it's being asked to operate on an NIS
user and it displayes the appropriate message in the editor
template ("Changing NIS information for foo"). After the changes
have been made, chpass will promte the user for his NIS password.
If the password is correct, the changes are committed to yppasswdd.

Hopefully, this should make NIS more transparent to the end user.

Note that even the superuser needs to know a user's password before
he can change any NIS information (such is the nature of yppasswdd).
Also, changes to the password field are not permitted -- that's what
yppasswd is for. (The superuser may specify a new password, but
again, he needs to know the user's original password before he can
change it.)
