bd6daf52d3 NO_ROOT: Create the METALOG directory on installworld/distributeworld.
When not using NO_ROOT the DESTDIR is implicitly created by the
distrib-dirs call.  However with NO_ROOT it is trying to write
to the METALOG right away before running distrib-dirs which
may fail.

c501d73c7e Convert casperd(8) daemon to the libcasper.
After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.

3a3f435f98 Include a 'package-pkg' target, intended for use for
architectures we do not provide upstream pkg(8) packages.

This is not tied to anything as-is, and likely will break
your system if used (based on experience with testing with
powerpc).

There is an overwhelming amount of evil happening here,
so until the issues are fixed, it will not be tied into the
'packages' target.

4821f9ed5b Always include the kernel name in the resulting package.
While functionally expected to be a no-op on big-iron hardware,
embedded hardware (arm, mips) do not have a GENERIC kernel, so
the KERNCONF value must be included in the package to avoid
conflicting packages for the default kernel (RPI-B versus RPI2,
for example).

While here, correct the kernel name in the metadata.

71b7fa1252 Simplify running the FreeBSD test suite
Replace `make regress` (legacy test make target) and `make test` (incomplete
test make target added with the FreeBSD test suite) with make check as it's
consistent with other open source projects.

`make check` defaults to running tests from `.OBJDIR`, but can be overridden
with the `CHECKDIR` variable.

Add `make checkworld` target to simplify running the FreeBSD test suite from
`TESTSBASE` (i.e. the top-level tests directory), similar to buildworld.

Document `make check` and `make checkworld` in build(7).

Other minor changes:

- Rename intermediate file (`Kyuafile.auto`) to `Kyuafile` to simplify
  `make check`.
- Remove terse warnings attached to `beforetest`/`aftertest`.
- Add kyua binary check to check target in suite.test.mk; error out if it's
  not found

The MFC is [partly] contingent on other build related changes being MFCed.

5c52b2f5ca Rework the way <packagename>.ucl files are generated.
One of the major pain points with how this was implemented
is the requirement of in-tree, hard-coded <name>.ucl, as
well as <name>-<suffix>.ucl where <suffix> can be lib32,
profile, development, debug, or any combination of the four.

This created significant overhead when adding new packages
and any of the files in any of the combinations were missing.

Instead of test(1)-ing if the <packagename>.ucl file exists,
hand off to a script to figure out what the final ucl file
name should be before invoking pkg(8).

The default behavior is 'template.ucl' is used as a fallback.

This affects only the userland packages, as the kernel code
is already smart enough to handle these variations.

03173d2ff0 bsd.subdir.mk: Only recurse on called targets, rather than dependencies.
This is to fix 'make all' causing it to recurse on both 'all' and 'buildconfig'
due to 'buildconfig' being in ALL_SUBDIR_TARGETS and being a dependency of
'all'.

This now adds all of the '*includes', '*files' targets as subdir targets,
allowing them to recurse.

This also removes the need for some 'realinstall' hacks in bsd.subdir.mk since
it no longer recurses; only 'install' will recurse and call the proper
'beforeinstall', 'realinstall', and 'afterinstall' in each sub-directory.

This fixes 'make includes' and 'make files' to not be a rerolled ${MAKE}
sub-shell but to rather just recurse on 'inclues' and 'files'.  This avoids
various issues such as the one fixed in r289462.  As such revert Makefile.inc1
back to using 'includes' which avoids an extra tree walk and parallelizes
the includes phases better.

Makefile.inc1 includes a guard so that 'make all' will not use SUBDIR_PARALLEL,
added in r289438.  This is so users do not get a probably broken build if they
run 'make all' from the top-level.  Before the change in this commit, the
workaround for 'make everything' was 'par-all' which would depend on 'all' and
cause a proper parallel recursion.  Now that will not work so a new
_PARALLEL_SUBUDIR_OK is used to allow it.

This is still part of an effort to combine bsd.(files|incs|confs).mk and move
some of its logic out of bsd.subdir.mk, as attempted in r289282 and reverted in
r289331.  This commit fixes the problems found there which was mostly double
recursing during 'includes' which would recurse on itself and 'buildincludes'
and 'installincludes', all in parallel.  The logic is still in bsd.subdir.mk
for now.

I've been cautious about this commit but have experienced no breakage on the
tree except for the 'par-all' case which was already a hack.  If something foo
is depending on something bar that should recurse, it is very likely that the
foo target is being recursed on already meaning that bar will still effectively
recurse once sub-directories call foo.

b67490a3b0 Fix errors being ignored in many phases of the build since the bmake integration.
Say it with me, "I will not chain commands with && in Makefiles"

This was originally fixed and explained quite well by bde@ in r36074.  The
initial bmake integration caused 'set -e' to stop being used which lead to
r252419.  Later 'set -e' expectations were fixed with bmake in r254980.

Because of the && here, errors would be ignored when building in parallel and
a dependency failed.  Such as bootstrap-tools since it builds everything in
parallel.  If any tool failed in obj/depend/all, it would just ignore the error
and continue to build.  This later would result in cascaded errors that only
confused the real issue.  This could also cause commands after the failed
command to still execute, leading to more confusion.

This should be fine if the command is in a sub-shell such as: (cmd1 && cmd2)

This reverts r252419.

7f911abe54 Add support to libkvm for reading vmcores from other architectures.
- Add a kvaddr_type to represent kernel virtual addresses instead of
  unsigned long.
- Add a struct kvm_nlist which is a stripped down version of struct nlist
  that uses kvaddr_t for n_value.
- Add a kvm_native() routine that returns true if an open kvm descriptor
  is for a native kernel and memory image.
- Add a kvm_open2() function similar to kvm_openfiles().  It drops the
  unused 'swapfile' argument and adds a new function pointer argument for
  a symbol resolving function.  Native kernels still use _fdnlist() from
  libc to resolve symbols if a resolver function is not supplied, but cross
  kernels require a resolver.
- Add a kvm_nlist2() function similar to kvm_nlist() except that it uses
  struct kvm_nlist instead of struct nlist.
- Add a kvm_read2() function similar to kvm_read() except that it uses
  kvaddr_t instead of unsigned long for the kernel virtual address.
- Add a new kvm_arch switch of routines needed by a vmcore backend.
  Each backend is responsible for implementing kvm_read2() for a given
  vmcore format.
- Use libelf to read headers from ELF kernels and cores (except for
  powerpc cores).
- Add internal helper routines for the common page offset hash table used
  by the minidump backends.
- Port all of the existing kvm backends to implement a kvm_arch switch and
  to be cross-friendly by using private constants instead of ones that
  vary by platform (e.g. PAGE_SIZE).  Static assertions are present when
  a given backend is compiled natively to ensure the private constants
  match the real ones.
- Enable all of the existing vmcore backends on all platforms.  This means
  that libkvm on any platform should be able to perform KVA translation
  and read data from a vmcore of any platform.

20f680588a Remove unneeded libmd from bootstrap-tools (reverting r246784).
The bootstrap-tools are supposed to be host tools, which in most cases, use
host headers and libraries.  As such, directly including the src tree's headers
for libmd here causes the need to link libmd in since it will be built with
the new symbols (which /usr/lib/libmd.so) won't have unless it is new enough.
During the target build in buildworld the target headers are staged into
WORLDTMP and used via --sysroot, allowing the target xinstall to be built with
the new/target libmd.

The .PATH here was also not doing anything since xinstall does not use libmd
source files.

ddd945c7b5 Fix 'make cleanworld' to respect TARGET/TARGET_ARCH for cross-build objtrees.
This simplifies the logic to always try removing the objdir if it exists
and to fallback on a 'cleandir' if no objdir exists.  The reasoning for
this is to avoid rm -rf src/* (r126024)

9160419c7a Add built-in ccache build support via WITH_CCACHE_BUILD option.
ccache is mostly beneficial for frequent builds where -DNO_CLEAN is not
used to achieve a safe pseudo-incremental build.  This is explained in
more detail upstream [1] [2].  It incurs about a 20%-28% hit to populate the
cache, but with a full cache saves 30-50% in build times.  When combined with
the WITH_FAST_DEPEND feature it saves up to 65% since ccache does cache the
resulting dependency file, which it does not do when using mkdep(1)/'CC
-E'.  Stats are provided at the end of this message.

This removes the need to modify /etc/make.conf with the CC:= and CXX:=
lines which conflicted with external compiler support [3] (causing the
bootstrap compiler to not be built which lead to obscure failures [4]),
incorrectly invoked ccache in various stages, required CCACHE_CPP2 to avoid
Clang errors with parenthesis, and did not work with META_MODE.

The option name was picked to match the existing option in ports.  This
feature is available for both in-src and out-of-src builds that use
/usr/share/mk.

Linking, assembly compiles, and pre-processing avoid using ccache since it is
only overhead.  ccache does nothing special in these modes, although there is
no harm in calling it for them.

CCACHE_COMPILERCHECK is set to 'content' when using the in-tree bootstrap
compiler to hash the content of the compiler binary to determine if it
should be a cache miss.  For external compilers the 'mtime' option is used
as it is more efficient and likely to be correct.  Future work may optimize the
'content' check using the same checks as whether a bootstrap compiler is needed
to be built.

The CCACHE_CPP2 pessimization is currently default in our devel/ccache
port due to Clang requiring it.  Clang's -Wparentheses-equality,
-Wtautological-compare, and -Wself-assign warnings do not mix well with
compiling already-pre-processed code that may have expanded macros that
trigger the warnings.  GCC has so far not had this issue so it is allowed to
disable the CCACHE_CPP2 default in our port.

Sharing a cache between multiple checkouts, or systems, is explained in
the ccache manual.  Sharing a cache over NFS would likely not be worth
it, but syncing cache directories between systems may be useful for an
organization.  There is also a memcached backend available [5].  Due to using
an object directory outside of the source directory though you will need to
ensure that both are in the same prefix and all users use the same layout.  A
possible working layout is as follows:
  Source: /some/prefix/src1
  Source: /some/prefix/src2
  Source: /some/prefix/src3
  Objdir: /some/prefix/obj
  Environment: CCACHE_BASEDIR='${SRCTOP:H}' MAKEOBJDIRPREFIX='${SRCTOP:H}/obj'
This will use src*/../obj as the MAKEOBJDIRPREFIX and tells ccache to replace
all absolute paths to be relative.  Using something like this is required due
to -I and -o flags containing both SRC and OBJDIR absolute paths that ccache
adds into its hash for the object without CCACHE_BASEDIR.

distcc can be hooked into by setting CCACHE_PREFIX=/usr/local/bin/distcc.
I have not personally tested this and assume it will not mix well with
using the bootstrap compiler.

The cache from buildworld can be reused in a subdir by first running
'make buildenv' (from r290424).

Note that the cache is currently different depending on whether -j is
used or not due to ccache enabling -fdiagnostics-color automatically if
stderr is a TTY, which bmake only does if not using -j.

The system I used for testing was:
  WITNESS
  Build options: -j20 WITH_LLDB=yes WITH_DEBUG_FILES=yes WITH_CCACHE_BUILD=yes
  DISK: ZFS 3-way mirror with very slow disks using SSD l2arc/log.
        The arc was fully populated with src tree files and ccache objects.
  RAM: 76GiB
  CPU: Intel(R) Xeon(R) CPU L5520 @2.27GHz
       2 package(s) x 4 core(s) x 2 SMT threads = hw.ncpu=16

The WITH_FAST_DEPEND feature was used for comparison here as well to show
the dramatic time savings with a full cache.

a55d4ddd20 Add a hack to workaround ZSH as BUILDENV_SHELL breaking CPUTYPE.
ZSH considers CPUTYPE a magic variable that will be the output of 'uname -m'
even if already set in environment when starting up.

The CPUTYPE?= check in Makefile.inc1 and supporting overriding CPUTYPE
manually in the buildenv shell make automatic workarounds too tricky
here.  ZSH should really respect variables set in the environment before
trashing them.

SHELL defaults to 'sh' in share/mk/sys.mk, but is typically passed down by
the shell invoking make as well.  Rather than forcing all 'buildenv' users
to use plain /bin/sh, let them use their favorite shell.

7f1636b75e Let SUBDIR_OVERRIDE with 'make buildworld' be more useful.
Now it can be used to effectively "build in a subdir".  It will use the
'cross-tools', 'libraries', and 'includes' phases of 'buildworld' to properly
setup a WORLDTMP to use.  Then it will build 'everything' only in the
listed SUBDIR_OVERRIDE directories.  It is still required to list custom
library directories in LOCAL_LIB_DIRS if SUBDIR_OVERRIDE is something
that contains libraries outside of the normal area (such as
SUBDIR_OVERRIDE=contrib/ofed needing LOCAL_LIB_DIRS=contrib/ofed/usr.lib)

Without these changes, SUBDIR_OVERRIDE with buildworld was broken or hit
obscure failures due to missing libraries, includes, or cross compiler.

SUBDIR_OVERRIDE with 'make <target that is not buildworld>' will continue to
work as it did before although its usefulness is questionable.

With a fully populated WORLDTMP, building with a SUBDIR_OVERRIDE with
-DNO_CLEAN only takes a few minutes to start building the target
directories.  This is still much better than building unneeded things via
'everything' when testing small subset changes.  A BUILDFAST or
SKIPWORLDTMP might make sense for this as well.

- Add in '_worldtmp' as we still need to create WORLDTMP as later targets,
  such as '_libraries' and '_includes' use it.  This probably was avoiding
  calling '_worldtmp' to not remove WORLDTMP for debugging purposes, but
  -DNO_CLEAN can be used for that.

- '_legacy' must be included since '_build-tools' uses -legacy.
  The SUBDIR_OVERRIDE change came in r95509, while -legacy being part
  of build-tools came in r113136.

- 'bootstrap-tools' is still skipped as this feature is not for
   upgrades.

- Fix buildworld combined with SUBDIR_OVERRIDE not installing all includes.

  The original change for SUBDIR_OVERRIDE in r95509 kept '_includes'
  and '_libraries' as building everything possible as the SUBDIR_OVERRIDE
  could need anything from them.  However in r96462 the real 'includes'
  target was changed from manual sub-makes to just recursing 'includes'
  on SUBDIR, thus not all includes have been installed into WORLDTMP since then
  when combined with 'buildworld'.

  This is not done unless calling 'make buildworld' as it would be
  unexpected to have it go into all directories when doing 'make
  SUBDIR_OVERRIDE=mydir includes'.

- Also need to build the cross-compiler so it is used with --sysroot.
  If this is burdensome then telling the build to use the local compiler
  as an external compiler (thus using a proper --sysroot to WORLDTMP) is
  possible by setting CC=/usr/bin/cc, CXX=/usr/bin/c++, etc.

- Don't build the lib32 distribution with SUBDIR_OVERRIDE in buildworld
  since it won't contain anything related to SUBDIR_OVERRIDE.  Testing
  of the lib32 build can be done with 'make build32'.

- Document these changes in build.7

74c52c6526 Handle lib32 files during delete-old* when MK_LIB32=no.
Extend OptionalObsoleteFiles.inc to delete all lib32 files when MK_LIB32 is
set to no on a system that previously had lib32 libraries installed.

Also, to prevent "make delete-old-dirs" from always deleting lib32 directories
after an installworld, move the lib32 subtree to its own mtree file that only
gets applied when MK_LIB32=yes.

Test: Ran "make delete-old" and "make delete-old-libs" on a system that never
had MK_LIB32 enabled, and on a system where MK_LIB32 was enabled and later
disabled.  Did this both on amd64 and powerpc64.

Test: Ran "make tinderbox" without errors.

b02f187c44 Remove unneeded MK_CTF=no when MK_CDDL=no.
This has been handled since r228158 made MK_CTF dependent on MK_CDDL
in share/mk/bsd.opts.mk.

4c339735da Fix wrong PATH being set for world 'includes' stage after r289438.
The 'includes' target is currently a pseudo target in bsd.subdir.mk that
does 'cd ${.CURDIR} && ${MAKE} buildincludes && ${MAKE} installincludes',
versus all over targets that just recurse.

In Makefile.inc1 the older duplicated bsd.subdir.mk logic for calling
'includes' was being executed in each subdir directly, meaning 'cd lib && make
includes' became 'cd lib && make buildincludes && make installincludes'.  Now
that the bsd.subdir.mk logic is used it is calling 'make buildincludes && make
installincludes' from the top-level which pulls in the PATH=<default path>
from /Makefile.

The sub-make logic for 'includes' in bsd.subdir.mk was attempted to be removed
in r289282 but turned out to be wrong.  I have a working version now but
it is not yet ready for commit.  So for now in Makefile.inc1 split out
'includes' to 'buildincludes' and 'installincludes' which will avoid the
problem.

53c0e6d54b For 'buildenvvars' show any .exported variables as well to cover recent
exporting of OSRELDATE and VERSION.  These already do export to 'buildenv'
fine.

a378087d24 Always export VERSION to the environment to avoid looking it up again in
sub-makes.

Some of the world phases that used plain '${MAKE} -f Makefile.inc1' were not
passing this variable along which caused them to look it up again.  By
using bmake's .export we can remove it from all of the other environment
lines.

Add a comment about the usage for VERSION for ctfmerge.

470c2b3af1 Export OSRELDATE so sub-makes don't look it up again.
We pass BOOTSTRAPPING=${OSRELDATE} to some of the sub-makes.  Rather than
chase every ${MAKE} invokation, just export it as bmake lets us.
