:U:Mfoo expands to :Mfoo, apparently. Explicit check for CPUTYPE being
defined, and test for it's value not containing *soft* before calling CRTARCH
armhf.
Tested, somewhat. Unfortunately recent changes appear to have affected
cross-builds where it no longer works, per my tests after universe12a being
upgraded from 07/2017 to 11/2017 sources (DESTDIR isn't being used in WORLDTMP;
MK_SYSTEM_COMPILER might be causing issues right now).

CPUTYPE (apparently) isn't defined in non-cross-builds, which caused
arm/armv[67] hosted/targeted builds to fail when evaluating CPUTYPE.
Add the :U modifier to CPUTYPE so it evaluates to "". This allows armv[67] to
get past the conditional successfully.

- MK_PROFILE is controlled in bsd.opts.mk, which is pulled in via bsd.own.mk,
which is pulled in via bsd.init.mk . All upstream Makefiles which build off
of this one use bsd.init.mk.
- COMPILER_{TYPE,VERSION} is set via bsd.compiler.mk .
This reduces the namespace pollution/complexity somewhat.

Despite the fact that it's a working solution, it doesn't follow the design
philosophy of only doing TARGET_* in Makefile.inc1 and special locations in

- Define TARGET_CPUARCH and use in libclang_rt as the basis for CRTARCH
When cross-compiling, the wrong architecture was being embedded in the
libclang_rt binary filenames. It should be based on TARGET_ARCH (target), not
MACHINE_ARCH (host).
If TARGET_ARCH isn't defined (host-builds), fallback to MACHINE_ARCH.
- Define CRTARCH to armhf when TARGET/TARGET_ARCH are set to arm/armv[67]
TARGET_ABI/TARGET_CPU in Makefile.inc1 sets the ABI to gnueabihf, which
affects the clang lookup path per `getArchNameForCompilerRTLib(..)` in
contrib/llvm/tools/clang/lib/Driver/ToolChain.cpp, so chase clang and
Linux's assumed naming convention for hard-float arm architectures.
CROSSENV (in Makefile.inc1) sets CPUTYPE/MACHINE(_ARCH)? to the
TARGET*-relevant values when building the `libraries` target, so test
those variables instead.
- Add OLD_FILES/OLD_LIBS entries for TARGET/TARGET_ARCH == arm/armv[67]. This
impacts only arm/armv6 and arm/armv7.

When trying to build world for MIPS64 with clang I was getting

It turns out std::get_new_handler() was not listed in Version.map so it was

The bug is an out-of-bounds read detected with address sanitizer that
happens when 'sp' in p_b_coll_elems() includes NUL byte[s], e.g. if it's
equal to "GS\x00". In that case len will be equal to 4, and the
strncmp(cp->name, sp, len) call will succeed when cp->name is "GS" but the
cp->name[len] == '\0' comparison will cause the read to go out-of-bounds.
Checking the length using strlen() instead eliminates the issue.
The bug was found in LLVM with oss-fuzz:

The idea behinds mocks is that we don't need to ifdef a lot of code in
tools itself but those defines are hidden in the casper library.
Right now the mocks are implemented as define/inlines functions.
There was a very long discussion how this should be implemented.
This approach has some advantages like we don't need to link to any additional
libraries. Unfortunately there are also some disadvantages for example it is
easy to get library out of sync between two versions of functions or that we
need extra define to compile program with casper support.
This isn't an ideal solution but it's good enough for now and should simplify
capsicumizing programs. This also doesn't close us any other ways to do those
mocks and this should evolve in time.

Previously, this didn't work because L2ARC devices' labels don't contain
pool GUIDs. Modify zfsd so that the pool GUID won't be required:
lib/libdevdctl/guid.h
Change INVALID_GUID from a uint64_t constant to a function that
returns an invalid Guid object. Remove the void constructor.
Nothing uses it, and it violates RAII.
cddl/usr.sbin/zfsd/case_file.h
cddl/usr.sbin/zfsd/case_file.cc
Allow CaseFile::Find to match a CaseFile based on Vdev GUID alone.
In CaseFile::ReEvaluate, attempt to online devices even if the newly
