bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
	GCC_NO_warning
to
	CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

Mostly merge changes from HEAD upto 20200411

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION    -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION  -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW    -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE   -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints.  many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

add LIBKRB5_LDADD/LIBKRB5_DPADD and their static counterparts
to bsd.prog.mk.  use them instead of hard coding various lists
of libraries for krb5.

this fixes static builds.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Remove redundant WARNS=5.

make krb5 compile again. XXX: one function left that is deprecated, what's
the new equivalent?
centralize error function processing.
fix the USE_KERBEROS=no USE_PAM=no build.
remove obsolete comment.
make kerberos work again:
1. make notickets external
2. don't use the tty as part of the credential cache, since pts/1 will not work.
3. Attempt to use the newer functions, but punt for now since it does not work
yet.
don't abuse the instance variable
move more of the compat code in the compat block.
last commit before I nuke the old code.
no more KRB5_DEPRECATED

make krb5 compile again. XXX: one function left that is deprecated, what's
the new equivalent?

We no longer need -I/usr/include/krb5.

PR/42540: Ed Ravin: /usr/bin/login does not log normal logins, and does not
log ip addresses.
- Factor out the common code in login.c and login_pam.c into common.c
- Always log a login event
- Check passed in sockaddr against the one from getpeername(2).

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

Enable WARNS=4 by default for usr.bin, except for:
	awk  bdes  checknr  compile_et  error  gss  hxtool  kgetcred  kinit
	klist  ldd  less  lex  locale  login  m4  man  menuc  mk_cmds
	mklocale  msgc  openssl  rpcgen  rpcinfo  sdiff  spell  ssh
	string2key  telnet  tn3270  verify_krb5_conf  xlint

Use ${TOOL_AWK} instead of ${AWK} or plain "awk" in make commands.
Pass AWK=${TOOL_AWK:Q} to shell scripts that use awk.

Be consistent about making USE_PAM!=no be exclusive to USE_SKEY!=no.

Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry.  RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros.  Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default.  Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

Goodbye KerberosIV

Introduce PAM_STATIC_LDADD and PAM_STATIC_DPADD.  When compiling
with MKPIC=no, possibly because the target does not support shared
libraries, these include libraries required to resolve all symbols
which end up referenced from PAM-using applications.  The libraries
presently required are -lcrypt, -lrpcsvc and -lutil.

Add use of these variables which are currently set up to use PAM,
so that they compile when MKPIC=no.

Also, in the telnetd case, reorder the order of the libraries, so
that libtelnet.a comes before -ltermcap and -lutil, again to fix
link error when MKPIC=no.

Discussed with thorpej and christos.

Add PAM support to login(8)

Kill __P(), ANSIfy, remove main() prototype, whitespace; WARNS=2

Generate the copyright string from sys/conf/copyright rather than
replicating it here.  Idea from Simon Burge.

Fix the checkflist for builds without Kerberos 4 (MKKERBEROS4=no)
and without Kerberos 4 & 5 (MKKERBEROS=no). Previously checkflist
complained of missing files.

* move kerberos- and kerberos 4-only files into new flists,
  distrib/sets/lists/*/krb.*

* make the flist generators grok MKKERBEROS{,4} variables

* fix Makefiles which treat MKKERBEROS=no as MKKERBEROS5=no.
  9 out of 10 experts agree that it is ludicrous to build w/
  KERBEROS4 and w/o KERBEROS5.

* fix header files, also, which treat MKKERBEROS=no as MKKERBEROS5=no.

* omit some Kerberos-only subdirectories from the build as
  MKKERBEROS{,4} indicate

(I acknowledge the sentiment that flists are the wrong way to go,
and that the makefiles should produce the metalog directly.  That
sounds to me like the right way to go, but I am not prepared to do
revamp all the makefiles.  While my approach is expedient, it fits
painlessly within the current build architecture until we are
delivered from flist purgatory, and it does not postpone our
delivery. Fair enough?)

libkrb depends on libdes, patch in private mail from
Harold Gutch logix at foobar franken de

split MKKERBEROS4 from MKKERBEROS.  based on work by lha at stacken.kth.se
(build confirmed with both MKKERBEROS4=yes and MKKERBEROS4=no)

add DPADD.

make this compile without SUPPORT_UTMPX

Factor out the utmp/wtmp/lastlog updating and add utmpx/wtmpx/lastlogx updating.
Both are turned on for now.

Split the notion of building Hesiod, Kerberos, S/key, and YP
infrastructure and using that infrastructure in programs.

	* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
	  of the infratsructure (libraries, support programs, etc.)

	* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
	  building of support for using the corresponding API
	  in various libraries/programs that can use it.

As discussed on tech-toolchain.

Pull up 1.34 [simonb]:
Remove INSTALLFLAGS=-fschg.

Fix library order.

Update from trunk:
Add MK... variables to enable/disable various aspects of building
crypto support into the system.  See share/mk/bsd.README for more
a full description.

file Makefile was added on branch netbsd-1-5 on 2000-06-24 06:59:36 +0000

Merge a bunch of things from crypto-us and crypto-intl into basesrc,
adding support for Heimdal/KTH Kerberos where easy to do so.  Eliminate
bsd.crypto.mk.

There is still a bunch more work to do, but crypto is now more-or-less
fully merged into the base NetBSD distribution.

Clean up changes a bit.

Re-enable login_cap processing, now that a non-existing login.conf
won't make it crash. Also make it less noisy in that case.

Ack. Disable login caps, until problems are fixed.

Add login.conf capability setting.

optionally include CRYPTOPATH Makefile.frag files.

Use bsd.crypto.mk.

Kerberos5 changes to login -- now supports forwarded TGTs.

Build domestic login on domestic systems.
Incorporated (minor) diff from domestic man page.

Remove the crypto-related bits until such time as we have a fully-
integrated source tree.  Export-controlled versions of these are now
built during the domestic build process.

don't define WARNS=1 here

SRCS must be defined *before* bsd.prog.mk is included...

Pull in bsd.own.mk for SKEY, KERBEROS, KERBEROS5.

CFLAGS->CPPFLAGS; Conditionalize SKEY

Various changes to keep up with krb5, mostly addition of the kcontext
structure.  From PR 3826, by Chris Jones.

* add functionality to `force password change at next login'. to use,
  set the pw_change field of the user to -1 (defined in <pwd.h> as
  _PASSWORD_CHGNOW). based on [bin/936] by Simon Gerraty <sjg@quick.com.au>
* clean up for WARNS?=1

Install statically linked, as suggested by mrg@eterna.com.au in [bin/1715].

Merged with 4.4lite.
Changed to conform to NetBSD's new RCS Id convention.

imported from 44lite

Add support for Kerberos5 authentication.
