r314451:

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

The SRCTOP conversion simplifies pathing in make/displayed output.

Also, while here, change a hardcoded path to ar5523.bin.uu in the make target
with ${.ALLSRC} .

r314453:

This simplifies pathing in make/displayed output.

r314468:

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

Also, use :H where possible/sensical to manipulate .CURDIR-relative paths

This simplifies pathing in make/displayed output.

r314470:

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

This simplifies pathing in make/displayed output.

r314472:

Simplify/improve idioms in usr.sbin/ntp Makefiles

- Use SRCTOP-relative paths to other directories instead of
.CURDIR-relative ones. This simplifies pathing in make/displayed output.
- Also, use :H where possible/sensical to manipulate .CURDIR-relative
paths
- Remove superfluous bsd.own.mk .includes which are already handled via
src.opts.mk .includes

r314478:

Simplify idioms in Makefiles further

- Use SRCTOP-relative paths instead of .CURDIR-relative ones where possible
- Use :H to manipulate .CURDIR in areas instead of ..-relative paths.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.

Fix overlinking again after recent ntp updates
Fix building WITHOUT_OPENSSL

MFV ntp 4.2.8p1 (r258945, r275970, r276091, r276092, r276093, r278284)

Thanks to roberto for providing pointers to wedge this into HEAD.

Convert usr.sbin to LIBADD
Reduce overlinking

Revert r267233 for now. PIE support needs to be reworked.

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

Reported by: kib

In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.

This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.

Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]

Mark known build failures as NO_PIE for now.

The only known runtime failure was rtld.

When building picobsd, define WITHOUT_OPENSSL and WITHOUT_KERBEROS and
remove the now-redundant checks for RELEASE_CRUNCH. This originally
was defined for building smaller sysinstall images, but was later also
used by picobsd builds for a similar purpose. Now that we've moved
away from sysinstall, picobsd is the only remaining consumer of this
interface. Adding these two options reduces the RELEASE_CRUNCH
special cases in the tree by half.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

Update the various files to sync with vendor import of 4.2.4p5.
sntp includes a copy of libopts in itself in vendor code, rewrite the
Makefile to compile and use only one copy. It is an internal library, not
installed.

MFC after: 2 weeks

Reimplementation of world/kernel build options. For details, see:

http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html

The src.conf(5) manpage is to follow in a few days.

Let bsd.prog.mk set SRCS and MAN to their default values.

NOCRYPT -> NO_CRYPT

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

Include support for NOCRYPT & NO_OPENSSL world.

It does survive « make release ».

Uses an upcoming patch from the vendor branch (ntp-stable) of ntp-keygen.

Submitted by: Marius Strobl <marius@alchemy.franken.de>

Update our ntpd to the long awaited 4.2.0 version.

This bring us several things:
- updated drivers
- IPv6 support at last
- ntp-genkeys is replaced by ntp-keygen
- ntptrace is now a script (courtesy of John Hay)
- lots of renamed files from .htm to .html (while I prefer .html, I
find the change a bit gratuitous)
- still no manpages :(

Please test and report.
