e2e76dee4d libbe(3): Fix be_import to delete temp snapshot
Deleting the temp snapshot isn't immediately possible because it's the
origin of the newly imported boot environment. However, this is trivially
solved by opening the new boot environment and promoting it. The roles are
now reversed and the temp snapshot/dataset may be completely destroyed.

Remove the BUGS from libbe(3) and bectl(8).

2f561e90ad getopt_long(3): Document behavior of leading characters in optstring
Leading '+', '-', and ':' in optstring have special meaning. We briefly
mention that the first two have special meaning in that we say
POSIXLY_CORRECT turns them off, but we don't actually document their
meaning. Add a paragraph to RETURN VALUES explaining how they control
the treatment of non-option arguments.

A leading ':' has no mention; add a note that it suppresses warnings about
missing arguments.

The mostly-undocumented 'add' functionality, from initial read-through, is

However, it's mostly broken at this point. `#if SOON` it out on both sides

c4b7f80c48 libbe(3): More error handling bits
be_add_child functionality gets split out into separate places as a bonus.
A lot of places here we'll gloss over libzfs errors, because they shouldn't
be happening given the conditions that we're operating under. "Unknown
error" is what I'm intending to use for the moment to indicate an
exceptional circumstance- exceptional enough that we can't tell the consumer
did because we're not so certain that they did anything.

fbc8c296ae In r308100, an explicit -fexceptions flag was added for the C sources
from LLVM's libunwind, which end up in libgcc_eh.a and libgcc_s.so.
This is because the unwinder needs the unwinder data for its own
functions.

However, for the C++ sources in libunwind, -fexceptions is already the
default, and this can have the side effect of generating a reference to
__gxx_personality_v0, the so-called personality function, which is
normally provided by the C++ ABI library (libcxxrt or libsupc++).

If the reference ends up in the eventual libgcc_s.so, linking any
non-C++ programs against it will fail with "undefined reference to
`__gxx_personality_v0'".

Note that at high optimization levels, the reference is usually
optimized away, which is why we have never noticed this problem before.

With clang 7.0.0 though, higher optimization levels don't help anymore,
since the addition of address-significance tables [1] in
<https://reviews.llvm.org/rL337339>.  Effectively, this always causes a
reference to __gxx_personality_v0.

After discussion with the upstream author of that change, it turns out
that we should compile libunwind sources with the -fno-exceptions
-funwind-tables flags instead.  This ensures unwind tables are
generated, but no references to any personality functions are emitted.

020056252b Add optional LLVM BPF target support
BPF (eBPF) is an independent instruction set architecture which is
introduced in Linux a few years ago. Originally, eBPF execute
environment was only inside Linux kernel. However, recent years there
are some user space implementation (https://github.com/iovisor/ubpf,
https://doc.dpdk.org/guides/prog_guide/bpf_lib.html) and kernel space
implementation for FreeBSD is going on
(https://github.com/YutaroHayakawa/generic-ebpf).

The BPF target support can be enabled using WITH_LLVM_TARGET_BPF, as it
is not built by default.

77af00cc81 Install the 32-bit compat sanitizer libraries.
The lib32 build was already building the i386 version of
the clang sanitizers (libclang_rt) but they were not being
installed.  This enables the installation.

MK_TOOLCHAIN=no was originally added to the install make
environment to disable includes so that NO_INCS could be
removed.  The MK_TOOLCHAIN in bsd.incs.mk was subsequently
renamed to MK_INCLUDES, but bsd.lib.mk doesn't even include
bsd.incs.mk when LIBRARIES_ONLY is defined which the install
make environment for compat libs now defines.  However,
setting MK_TOOLCHAIN=no forced MK_CLANG=no which disabled
libclang_rt during the install32 phase.  Remove MK_TOOLCHAIN=no
since LIBRARIES_ONLY is now sufficient.

Since the libcompat environment overrides both LIBDIR and
SHLIBDIR, libclang_rt/Makefile.inc has to set both variables
to force the libraries to be installed to the location
expected by the compiler.

b3776cb8de Make timespecadd(3) and friends public
The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.

Our kernel currently defines two-argument versions of timespecadd and
timespecsub.  NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions.  Solaris also defines a three-argument version, but
only in its kernel.  This revision changes our definition to match the
common three-argument version.

Bump _FreeBSD_version due to the breaking KPI change.

96e59fd889 Clean up execl*(3) manual page prototype formatting
Rendering of execle was missing a comma between the NULL argument and envp.

For unclear reasons, POSIX' definition of these routines comments out the
mandatory trailing NULL argument.  That seems unnecessary and probably
(reasonably) confuses mdoc.

For unclear reasons, POSIX' definition of these routines spells NULL as
"(char *)0."  This is needlessly unclear.  One guess might be that POSIX
targets more exotic computer architectures than FreeBSD does.  Fortunately,
there is no such problem on any reasonable platform for FreeBSD to support.
Spell NULL as NULL.

The comma was probably removed in r117204 while the comment and creative
spelling of NULL were added in r116537 (both 15 years ago).

4050420519 Allow a EVFILT_TIMER kevent to be updated.
If a timer is updated (re-added) with a different time period
(specified in the .data field of the kevent), the new time period has
no effect; the timer will not expire until the original time has
elapsed. This violates the documented behavior as the kqueue(2) man
page says (in part) "Re-adding an existing event will modify the
parameters of the original event, and not result in a duplicate
entry."

This modification, adapted from a patch submitted by cem@ to PR214987,
fixes the kqueue system to allow updating a timer entry. The
kevent timer behavior is changed to:

  * When a timer is re-added, update the timer parameters to and
    re-start the timer using the new parameters.
  * Allow updating both active and already expired timers.
  * When the timer has already expired, dequeue any undelivered events
    and clear the count of expirations.

All of these changes address the original PR and also bring the
FreeBSD and macOS kevent timer behaviors into agreement.

A few other changes were made along the way:

  * Update the kqueue(2) man page to reflect the new timer behavior.
  * Fix man page style issues in kqueue(2) diagnosed by igor.
  * Update the timer libkqueue system test to test for the updated
    timer behavior.
  * Fix the (test) libkqueue common.h file so that it includes
    config.h which defines various HAVE_* feature defines, before the
    #if tests for such variables in common.h. This enables the use of
    the actual err(3) family of functions.
  * Fix the usages of the err(3) functions in the tests for incorrect
    type of variables. Those were formerly undiagnosed due to the
    disablement of the err(3) functions (see previous bullet point).

c125d4a078 Make pw_scan(3) more compatible with getpwent(3) et. al. when processing
data from /etc/passwd rather than /etc/master.passwd.

The libc getpwent(3) and related functions automatically read master.passwd
when run by root, or passwd when run by a non-root user.  When run by non-
root, getpwent() copes with the missing data by setting the corresponding
fields in the passwd struct to known values (zeroes for numbers, or a
pointer to an empty string for literals).  When libutil's pw_scan(3) was
used to parse a line without the root-accessible data, it was leaving
garbage in the corresponding fields.

These changes rename the static pw_init() function used by getpwent() and
friends to __pw_initpwd(), and move it into pw_scan.c so that common init
code can be shared between libc and libutil.  pw_scan(3) now calls
__pw_initpwd() before __pw_scan(), just like the getpwent() family does, so
that reading an arbitrary passwd file in either format and parsing it with
pw_scan(3) returns the same results as getpwent(3) would.

This also adds a new pw_initpwd(3) function to libutil, so that code which
creates passwd structs from scratch in some manner that doesn't involve
pw_scan() can initialize the struct to the values expected by lots of
existing code, which doesn't expect to encounter NULL pointers or garbage
values in some fields.

- Rename 'active' to 'rootfs', which is used in other places to describe the
currently booted (or about to be booted) BE.

- Add 'bootfs', which indicates the next boot environment to be booted. This
  is pulled from the BOOTFS zpool property.

- Go ahead and keep an open handle to the active zpool. We might need to
  enumerate datasets, get properties, and set properties (e.g. bootfs)
  throughout other libbe bits, and a single handle isn't overly expensive.

a1af6319dc llvm: remove __FreeBSD_version conditionals
All supported FreeBSD build host versions have backtrace.h, so we can

osreldate.h.  This should reduce the frequency with which Clang gets

7a13690726 In C remquol() and thus also in C remainderl(), don't clobber the sign bit
of NaNs before possible returning a NaN.

The remquo*() and remainder*() functions should now give bitwise identical
results across arches and implementations, and bitwise consistent results
(with lower precisions having truncated mantissas) across precisions.  x86
already had consistency across amd64 and i386 and precisions by using the
i387 consistently and normally not using the C versions.  Inconsistencies
for C reqmquol() were first detected on sparc64.

remainder*(x, y) and remquo*(x, y, quo) were broken for y = 0 by changing
multiplication by y to addition of y.  (When y is 0, the result should be
NaN but became 1 for finite x.)

Use a new macro nan_mix_op() to give more control over the mixing, and
expand comments.

Recent re-testing missed finding this bug since I only tested the macro
version on amd64 and i386 and these arches don't use the C versions (they
use either asm versions or builtins).

f9cb61fe19 Centralize the complications for special efficient rounding to integers.
This was open-coded in range reduction for trig and exp functions.  Now
there are 3 static inline functions rnint[fl]() that replace open-coded
expressions, and type-generic irint() and i64rint() macros that hide the
complications for efficiently using non-generic irint() and irintl()
functions and casts.

Special details:

ld128/e_rem_pio2l.h needs to use i64rint() since it needs a 46-bit integer
result.  Everything else only needs a (less than) 32-bit integer result so
uses irint().

Float and double cases now use float_t and double_t locally instead of
STRICT_ASSIGN() to avoid bugs in extra precision.

On amd64, inline asm is now only used for irint() on long doubles.  The SSE
asm for irint() on amd64 only existed because the ifdef tangles made the
correct method of simply casting to int for this case non-obvious.

fa26c3e1e0 Fix scaling bugs which gave innaccuracies and spurious underflows in csqrt()
and csqrtl().

When one component is huge and the other is tiny, scaling down the tiny
component gave spurious underflow.

When both components are denormal, not scaling them up gave inaccuracies
of 34+ ulps on not very carefully selected args.  Fixing this reduces the
maximum error to 1.6 ulps on the same set of args (mosly not denormal ones).

The scaling used multiplication of a complex variable by 2, but clang messes
this on amd64 up by losing the sign of -0.0.  Calculate the components
separately, as is well known to be needed for operations on more exceptional
values.

6914d33dfe Add a macro nan_mix() and use it to get NaN results that are (bitwise)
independent of the precision in most cases.  This is mainly to simplify
checking for errors.  r176266 did this for e_pow[f].c using a less
refined expression that often didn't work.  r176276 fixes an error in
the log message for r176266.  The main refinement is to always expand
to long double precision.  See old log messages (especially these 2)
and the comment on the macro for more general details.

Specific details:
- using nan_mix() consistently for the new and old pow*() functions was
  the only thing needed to make my consistency test for powl() vs pow()
  pass on amd64.

- catrig[fl].c already had all the refinements, but open-coded.

- e_atan2[fl].c, e_fmod[fl].c and s_remquo[fl] only had primitive NaN
  mixing.

- e_hypot[fl].c already had a different refined version of r176266.  Refine
  this further.  nan_mix() is not directly usable here since we want to
  clear the sign bit.

- e_remainder[f].c already had an earlier version of r176266.

- s_ccosh[f].c,/s_csinh[f].c already had a version equivalent to r176266.
  Refine this further.  nan_mix() is not directly usable here since the
  expression has to handle some non-NaN cases.

- s_csqrt.[fl]: the mixing was special and mostly wrong.  Partially fix the
  special version.

- s_ctanh[f].c already had a version of r176266.

ae06cc7de5 Tweak documentation to RB_ constants to reflect current use
RB_ASKNAME is no longer instructions to the boot loader to request a
prompt for which kernel to boot. Instead, it asks for what the root
file system to use. RB_INITNAME is unused, and never has been in
FreeBSD as far as I can tell. Remove it from the documentation and fix
comment. RB_SELFTEST and RB_MINIROOT likewise (though they were
completely undocumented). These last three constants can likely just
be deleted as nothing references them (even to set useless bits).

RB_ASKNAME doesn't actually survive reboot, however, so needs to be
communicated to the bootloader via other means. If the bootloader sets

r336019 introduced ${SRCTOP}/sys to the include paths in order to pull in a

Fix instead by removing -I${SRCTOP}/sys and installing the libnv headers

107a344bbb This exposes ZFS user and group quotas via the normal
quatactl(2) mechanism.  (Read-only at this point, however.)
In particular, this is to allow rpc.rquotad query quotas
for NFS mounts, allowing users to see their quotas on the
hosts using the datasets.

The changes specifically:

* Add new RPC entry points for querying quotas.
* Changes the library routines to allow non-UFS quotas.
* Changes rquotad to check for quotas on mounted filesystems,
rather than being limited to entries in /etc/fstab
* Lastly, adds a VFS entry-point for ZFS to query quotas.

Note that this makes one unavoidable behavioural change: if quotas
are enabled, then they can be queried, as opposed to the current
method of checking for quotas being specified in fstab.  (With
ZFS, if there are user or group quotas, they're used, always.)

On 64-bit bit systems, the ABI is maintained. On 32-bit systems,
this is an ABI breaking change. The ABI of most of these structs
was previously broken in r315662.  This also imposes a small API
change on userspace consumers who must handle kernel pointers

0b35e16c23 Clean up the vcs ID strings in libc's gen/ directory.
- Move CSRG IDs into __SCCSID().
- When a file has been copied, consistently use 'From: <tag>' for strings
  referencing the version of the source file copied from in the license
  block comment.
- Some of the 'From:' tags were using $FreeBSD$ that was being expanded on
  each checkout.  Fix those to hardcode the FreeBSD tag from the file that
  was copied at the time of the copy.
- When multiple strings are present list them in "chronological" order,
  so CSRG (__SCCSID) before FreeBSD (__FBSDID).  If a file came from
  OtherBSD and contains a CSRG ID from the OtherBSD file, use the order
  CSRG -> OtherBSD -> FreeBSD.

7b757d1fe5 Strip __RCSID() and __SCCSID() strings by default when building libc.
This is in preparation for changes to update the various ID strings in
libc's source.  CSRG ID strings will use __SCCSID() and there are some
existing uses of __RCSID() for NetBSD ID strings already.  These are
generally under either an explicit #if 0 or an #ifdef LIBC_SCCS so are
off by default and this change preserves that existing behavior.

f0a89858e1 Rework check for libclang_rt to see if the needed library exists.
Currently libclang_rt is not provided for cross-building and as such
is not connected to cross-tools.  For building clang once in universe
it is likely that libclang_rt won't exist for the universe toolchain
but even if it did it would not support anything but the native arch.
So explicitly check for support before enabling h_raw.

4fcfcecfa8 geli attach multiple providers
Allow attaching of multiple geli providers at once if they use same
passphrase and keyfiles.

This is helpful when the providers being attached are not used for boot,
and therefore the existing code to first try the cached password when
tasting the providers during boot does not apply.

Multiple providers with the same passphrase and keyfiles can be attached
at the same time during system start-up by adding the following to
rc.conf:
  geli_groups="storage backup"
  geli_storage_flags="-k /etc/geli/storage.keys"
  geli_storage_devices="ada0 ada1"
  geli_backup_flags="-j /etc/geli/backup.passfile -k /etc/geli/backup.keys"

9fa168b01a Normalize the g(eom,cache,part,...) build.
Rather then combining hardlink creation for the geom(8) binary with
shared library build, move libraries to src/lib/geom so they are
built and installed normally.  Create a common Makefile.classes
which is included by both lib/geom/Makefile and sbin/geom/Makefile
so the symlink and libraries stay in sync.

The relocation of libraries allows libraries to be build for 32-bit
compat.  This also reduces the number of non-standard builds in
the system.

This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit
system out of the box as it will look in the wrong place for libraries
unless GEOM_LIBRARY_PATH is set appropriatly in the environment.

363a71e8bc Revert r335449 and add needed MK_LLD_BOOTSTRAP check for SRCS_MIW.
This effectively reverts r335449 and changes the previous MK_LLD_IS_LD
to a MK_LLD_BOOTSTRAP check.  If !TOOLS_PREFIX then these sources are
always built for llvm-objdump, lld, and llvm-cov.  When TOOLS_PREFIX
is set then they are only needed if lld is being bootstrapped.

6ee1d5b597 Add support for selectively enabling LLVM targets
This makes it possible, through src.conf(5) settings, to select which
LLVM targets you want to build during buildworld.  The current list is:

* (WITH|WITHOUT)_LLVM_TARGET_AARCH64
* (WITH|WITHOUT)_LLVM_TARGET_ARM
* (WITH|WITHOUT)_LLVM_TARGET_MIPS
* (WITH|WITHOUT)_LLVM_TARGET_POWERPC
* (WITH|WITHOUT)_LLVM_TARGET_SPARC
* (WITH|WITHOUT)_LLVM_TARGET_X86

To not influence anything right now, all of these are on by default, in
situations where clang is enabled.

Selectively turning a few targets off manually should work.  Turning on
only one target should work too, even if that target does not correspond
to the build architecture.  (In that case, LLVM_NATIVE_ARCH will not be
defined, and you can only use the resulting clang executable for
cross-compiling.)

I performed a few measurements on one of the FreeBSD.org reference
machines, building clang from scratch, with all targets enabled, and
with only the x86 target enabled.  The latter was ~12% faster in real
time (on a 32-core box), and ~14% faster in user time.  For a full
buildworld the difference will probably be less pronounced, though.

MK_LLD is for the installed lld while MK_LLD_BOOTSTRAP is for the build

MK_LLD_BOOTSTRAP should be checked instead.
