This makes the be_exists behavior match the comments that assert that we've

Other changes of note:
- bectl_list sees another change; changing mountpoint based on mount status

d06f71037b libbe(3): Rewrite activate temp bits to rely less on loader
Loader is still relied upon at the beginning of libbe to specify the be
root, but we can derive from that the primary zpool and any vdevs that we
need to set nextboot bits on.

This lets me successfully `bectl activate -t test`, but UEFI loader doesn't
quite yet understand so it's effectively defunct.

the same information as be_get_bootenv_props but for snapshots of the given

52f9bacb0e 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.

6040822c4e 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.

bbc5c8ee32 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).

95c05062ec 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).

34e9190d82 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

- 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.

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.

27aa844253 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.

b7092eef4d Fix spurious and extra underflows and resulting inaccuracies for some cases
with 1 huge component and 1 tiny (but nowhere near denormal) component.
Rescale earlier so that a scale factor of 2 can be combined with a non-
scale divisor of 2, so that the division doesn't shift out a bit.  In the
usual case where the scale factor is just 1, the division may shift out a
bit, but then the underflow is not spurious and the inaccuracies are harder
to fix.

9d7dc13615 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.

6f1b8a0792 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.

bdea3adca6 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
it, though, it will be honored.

3cafc9a654 config(8): Fix broken ABI
r336019 introduced ${SRCTOP}/sys to the include paths in order to pull in a
new sys/{c,}nv.h. This is wrong, because the build tree's ABI isn't
guaranteed to match what's running on the host system.

Fix instead by removing -I${SRCTOP}/sys and installing the libnv headers
with `make -C lib/libnv includes`... this may or may not get re-worked in
the future so that a userland lib isn't installing includes from sys/.

aad5531e71 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.)

f38b68ae8a Make struct xinpcb and friends word-size independent.
Replace size_t members with ksize_t (uint64_t) and pointer members
(never used as pointers in userspace, but instead as unique
idenitifiers) with kvaddr_t (uint64_t). This makes the structs
identical between 32-bit and 64-bit ABIs.

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
becoming virtual addresses.

c1920558b3 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.

off by default and this change preserves that existing behavior.
