ad8abd6c4d Disable SSP on arm for the time being.
The segfaults when using SSP seem to be a gcc bug, a patch is available
in the gcc bugzilla, and will be imported once it's committed
into the official gcc tree.

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

d57e5bc480 Properly alphabetize the BSD_CPIO option 2008-06-16 07:23:12 +00:00
Doug Barton
6973701a00 1. Make the BSD version of cpio the default [1]
a. The BSD version will be built and installed unless
WITHOUT_BSD_CPIO is defined.
b. The GNU version will not be built or installed unless
WITH_GNU_CPIO is defined. If this is defined, the symlink
in /usr/bin will be to the GNU version whether the BSD
version is present or not.

When these changes are MFCed the defaults should be flipped.

2. Add a knob to disable the building of GNU grep. This will
make it easier for those that want to test the BSD version in
the ports.

2e598474fa Remove ISDN4BSD (I4B) from HEAD as it is not MPSAFE and
parts relied on the now removed NET_NEEDS_GIANT.
Most of I4B has been disconnected from the build
since July 2007 in HEAD/RELENG_7.

This is what was removed:
- configuration in /etc/isdn
- examples
- man pages
- kernel configuration
- sys/i4b (drivers, layers, include files)
- user space tools
- i4b support from ppp
- further documentation

770ac3b21f Add support for the Compact C Type (CTF) conversions throughout FreeBSD's
system makefiles.

Note that the CTF conversion defaults to off. We may choose to change this
default later if DTrace proves popular and people are prepared to wear
the compilation performance impact of compiling with debug symbols all the
time.

Setting NO_CTF in the make args or user environment turns off CTF conversion.
Even if we choose to default CTF generation to on later, we still need
NO_CTF so that the buildworld process can bootstrap the tools without
needlessly generating CTF data for temporary tools.

Setting WITH_CTF in the make args or user environment (and _NOT_ in
/etc/make.conf) is the only way to enable CTF data conversion. Nore that
this can't be implemented the same way that the WITH_ and WITHOUT_ stuff
is implemented throughout the buildworld because the CTF conversion needs
to work when building a simple object without a Makefile, using the
default rules in sys.mk.

Typing 'make test.o' with no makefile and just a source file test.c
should work. Also, typing 'make WITH_CTF=1 test.o without a makefile and
just a source file test.c should work and produce an object with a CTF
elf section. Typing 'make WITH_CTF=1 CFLAGS=-g test.o' without a makefile
and just a source file test.c should produce an object with both a CTF
elf section and the debug elf sections.

In the FreeBSD build where more .mk files are used than just sys.mk
which is included my make by default, the use of DEBUG_FLAGS is the
correct way to enable a debug build. The important thing to note here
is that it is the DEBUG_FLAGS setting that prevents libraries and
programs from being stripped on installation. So, for the addition of
CTF data conversion, setting DEBUG_FLAGS to contain -g, without NO_CTF,
will cause the ctfconvert and ctfmerge build programs to be executed
also with the -g arg so that debug symbols are retained rather than
being removed after the CTF data elf section has been added.

Add DTrace libraries to the list of libnames.

321578e3d0 Connect MPC85XX to the PowerPC build.
The kernel config file is KERNCONF=MPC85XX, so the usual procedure applies:

1. make buildworld TARGET_ARCH=powerpc
2. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX

This default config uses kernel-level FPU emulation. For the soft-float world
approach:

1. make buildworld TARGET_ARCH=powerpc TARGET_CPUTYPE=e500
2. disable FPU_EMU option in sys/powerpc/conf/MPC85XX
3. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX

0d7cc1d0eb Normally, when a header file is removed from the build (as i4b headers
were recently), a simple 'make cleandepend; make depend' is sufficient
to keep the tree buildable after a cvs update when doing incremental
builds.

However, kdump and truss use a script which searches for header files
that define ioctls, and generates C code that includes them.  This
script will usually not need updating when a header file is removed,
so the normal dependency mechanism will not realize that it needs to
be re-run.  One is therefore left with code that references dead files
but will only be removed by a full 'make clean', which defeats the
purpose of incremental builds.

To work around this, modify the cleandepend target in bsd.dep.mk to
also remove any files listed in a new variable named CLEANDEPFILES,
and modify kdump's and truss's Makefiles accordingly.

  MK_* variables which itself is questionable.)

3fe21f77bc Hide the building and installation of libgssapi behind the
WITHOUT_KERBEROS knob. While GSS can be used for other things
some third party software (most notably ports/x11/kdelibs3)
takes the presence of libgssapi as an indication that kerberos
is available, and attempts to link with the kerberos libs. If
they are not available, the build will fail.

Because you might want to use GSS but not kerberos, add a knob
to re-enable it if WITHOUT_KERBEROS is present.

Document the new knob, and the new behavior of WITHOUT_KERBEROS.

221a97c194 Although the entire src tree builds cleanly now without -fno-strict-aliasing
in the default CFLAGS, we're in the middle of a ports freeze, so we can't
really go making the corresponding change to the ports mk files.

cfb5b3256b Re-enable -Werror again.
This time, change the default CFLAGS to match the simple defaults that
the tinderboxes use. That is, don't use -fno-strict-aliasing by default.

My last attempt to re-anable -Werror gave me a lesson in what strict
aliasing is all about. There was code in libthr that wasn't 64-bit clean.
The default use of -fno-strict-aliasing hid that.

By using -fno-strict-aliasing by default we were choosing to ignore
problems in code which had the potential to shoot ourselves in the
foot. Sometimes it would be the 64-bit foot. I have both feet. The left
ones are 32 bits and the right ones are 64 bits. Don't ask about my
endian orientation. :-)

The -fno-strict-aliasing compiler arg can still be used if NO_STRING_ALIASING
is define in make.

We are early in the FreeBSD 8 development, so we have the opportunity to
wait and see if this works for us. I am sure that people will complain.
We can easily revert this. All I ask is that we take sides: clean code or
not. YMMV.

Note that by using -fno-strict-aliasing the build won't actually break.
Only where WARNS is set (and -Werror is used) will a compiler warning break
the build. The use of WARNS levels implies (to me at least) that the
developer has taken some care to make the code pass basic checks. This
commit makes those checks just a little bit more strict.

f9f50330f3 Unfortunately the tinderbox setup uses custom CFLAGS which are a big
obstacle to enabling -Werror. I'll continue to work on cleaning up the
code so that we can keep this enabled.

If the tinderboxes would just use the default CFLAGS set in this file,
all would be fine and we'd be able to make use of -Werror.
