tls 4147a3c54a 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.

lukem efcc9a4c9d * Add user-controlled mk.conf variables
- SHLIBDIR	Location to install shared libraries if ${USE_SHLIBDIR}
			is "yes".  Defaults to "/usr/lib".

	- USE_SHLIBDIR	If "yes", install shared libraries in ${SHLIBDIR}
			instead of ${LIBDIR}.  Defaults to "no".
			Sets ${_LIBSODIR} to the appropriate value.
			This may be set by individual Makefiles as well.

	- SHLINKDIR	Location of shared linker.  Defaults to "/usr/libexec".
			If != "/usr/libexec", change the dynamic-linker
			encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
	libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
	libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
  to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

  1.)	If nothing is set or changed, there is no change from the
	current behaviour:
		- Static /bin, /sbin, and bits of /usr/*
		- Dynamic rest
		- Shared linker is /usr/libexec/ld*so

  2.)	If the following make variables are set:
		LDSTATIC=
		SHLINKDIR=/lib
		SHLIBDIR=/lib
	Then the behaviour becomes:
		- Dynamic tools
		- .so libraries used by /bin and /sbin are installed to /lib,
		  with symlinks from /usr/lib/lib*so to -> /lib/lib*so
		  where appropriate
		- Shared linker is /lib/ld*so

  3.)	As per 2.), but add the following variable:
		USE_SHLIBDIR=yes
	This forces all .so's to be instaleld in /lib (with compat
	symlinks), not just those tagged by their Makefiles to be.
	Again, compat symlinks are installed

itojun fb26763771 make z_off_t into off_t, which used to be "long" by mistake.
backward compatibility functions are supplied.

XXX increase shlib major, or minor?

garbled 61abb01179 libz works much better when the examples aren't compiled into the
library.  This caused severe pain with c++, as the example contained
a main().

lukem 5542a7ca43 - define WARNS?=1 in the top-level Makefile.inc, and don't define
anywhere else.
- for now, override WARNS=0 in librpcsvc and libwrap, until they're
  cleaned up
- rcsid police

lib is now clean (except for librpcsvc and libwrap) on the i386, and
this should motivate the other ports to fix any other minor problems
that their compilers pick up that the i386 version doesn't.

veego 3d60b93f30 Remove the uneeded HDRS= line and add zconf.h to the INCS= line. 1997-05-25 22:58:09 +00:00
gwr 371ce0e795 Remove _ZLIB_PRIVATE and all related changes. The "exported" API
of this library includes the typedefs in zconf.h so export it too.
Our zlib should now work with "png" (fixes PR lib/3030).

cgd 9118c05a03 RCS ID police: add NetBSD RCS IDs to everything. Since it was imported with
normal RCS IDs apparently unmodified (i.e. they were clobbered), remove
the normal Id tags so they cause fewer conflicts later.

cgd 98a5e78a03 clean up 'make test' so that it works even in the presence of
'obj' dirs, and added minigzip to CLEANFILES.

gwr de831ea222 Separate interface from implementation so that zlib.h can be
included without the other, private header files.  Only zlib.h
should be installed in /usr/include; all others are private.
The Makefile has a "test" rule to verify that minigzip.c can
be compiled using only zlib.h (and that it actually works).
Note: This file has extensive modifications.
