fd2a8c5a25 - snprintf() returns at most size-1 of the chars printed into
the buffer.  (n == hostlen) also means the buffer length was
  too short.

- Use sdl->sdl_data only when (sdl->sdl_nlen > 0 && sdl->sdl_alen == 0)
  to prevent redundant output.

3d333a281e Fix t_spawnattr test for attributes handling by posix_spawn(3).
Connect it to the build.

The code assumed that SCHED_* constants form a contiguous set of
numbers, remove the assumption by using schedulers[] array in
get_different_scheduler().  This is no-op on FreeBSD, but improves
code portability.

The selection of different priority used the min/max priority range of
the current scheduler class, instead of the priority to be changed to.
The bug caused the test failure.

Remove duplication of POSIX_SPAWN_SETSIGDEF flag and now unused
duplications of MIN/MAX definitions.

146b187d13 Switch libc from using _sig{procmask,action,suspend} symbols, which
are aliases for the syscall stubs and are plt-interposed, to the
libc-private aliases of internally interposed sigprocmask() etc.

Since e.g. _sigaction is not interposed by libthr, calling signal()
removes thr_sighandler() from the handler slot etc.  The result was
breaking signal semantic and rtld locking.

The added __libc_sigprocmask and other symbols are hidden, they are
not exported and cannot be called through PLT.  The setjmp/longjmp
functions for x86 were changed to use direct calls, and since
PIC_PROLOGUE only needed for functional PLT indirection on i386, it is
removed as well.

The PowerPC bug of calling the syscall directly in the setjmp/longjmp
implementation is kept as is.

The functionality of the wordexp builtin is easily replaced using normal

This does not mean that wordexp() will remain shell-independent -- a fully
reliable implementation of WRDE_NOCMD is really only possible using
extensions to the shell, or by adding much of the shell's code to libc.

11a5726cda The collate functions within libc have been using version 1 and 1.2 of the
packed LC_COLLATE binary formats. These were generated with the colldef
tool, but the new LC_COLLATE files are going to be generated by the new
localedef tool using CLDR POSIX files as input.  The BSD-flavored
version of localedef identifies the format as "BSD 1.0".  Any
LC_COLLATE file with a different version will simply not be loaded, and
all LC* categories will get set to "C" (aka "POSIX") locale.

This work is based off of Nexenta's contribution to Illumos.
The integration with xlocale is John Marino's work for Dragonfly.

The following commits will enable localedef tool, disable the colldef
tool, add generated colldef directory, and finally remove colldef from
base.

The only difference with Dragonfly are:
- a few fixes to build with clang
- And identification of the flavor as "BSD 1.0" instead of "Dragonfly 4.4"

c03b18934d Disable SSE in libthr
Clang emits SSE instructions on amd64 in the common path of
pthread_mutex_unlock.  If the thread does not otherwise use SSE,
this usage incurs a context-switch of the FPU/SSE state, which
reduces the performance of multiple real-world applications by a
non-trivial amount (3-5% in one application).

Instead of this change, I experimented with eagerly switching the
FPU state at context-switch time.  This did not help.  Most of the
cost seems to be in the read/write of memory--as kib@ stated--and
not in the #NM handling.  I tested on machines with and without
XSAVEOPT.

One counter-argument to this change is that most applications already
use SIMD, and the number of applications and amount of SIMD usage
are only increasing.  This is absolutely true.  I agree that--in
general and in principle--this change is in the wrong direction.
However, there are applications that do not use enough SSE to offset
the extra context-switch cost.  SSE does not provide a clear benefit
in the current libthr code with the current compiler, but it does
provide a clear loss in some cases.  Therefore, disabling SSE in
libthr is a non-loss for most, and a gain for some.

I refrained from disabling SSE in libc--as was suggested--because
I can't make the above argument for libc.  It provides a wide variety
of code; each case should be analyzed separately.

4a54322f0b Make it possible to implement poll(2) on top of kqueue(2).
It looks like EVFILT_READ and EVFILT_WRITE trigger under the same
conditions as poll()'s POLLRDNORM and POLLWRNORM as described by POSIX.
The only difference is that POLLRDNORM has to be triggered on regular
files unconditionally, whereas EVFILT_READ only triggers when not EOF.

Introduce a new flag, NOTE_FILE_POLL, that can be used to make
EVFILT_READ and EVFILT_WRITE behave identically to poll(). This flag
will be used by cloudlibc's poll() function.

abef15cd81 Copy the fencing of the algorithm to do lock-less update and reading
of the timehands, from the kern_tc.c implementation to vdso.  Add
comments giving hints where to look for the algorithm explanation.

To compensate the removal of rmb() in userspace binuptime(), add
explicit lfence instruction before rdtsc.  On i386, add usual
complications to detect SSE2 presence; assume that old CPUs which do
not implement SSE2 also execute rdtsc almost in order.

459f42dd55 Make shutdown() return ENOTCONN as required by POSIX, part deux.
Summary:
Back in 2005, maxim@ attempted to fix shutdown() to return ENOTCONN in case the socket was not connected (r150152). This had to be rolled back (r150155), as it broke some of the existing programs that depend on this behavior. I reapplied this change on my system and indeed, syslogd failed to start up. I fixed this back in February (279016) and MFC'ed it to the supported stable branches. Apart from that, things seem to work out all right.

Since at least Linux and Mac OS X do the right thing, I'd like to go ahead and give this another try. To keep old copies of syslogd working, only start returning ENOTCONN for recent binaries.

I took a look at the XNU sources and they seem to test against both SS_ISCONNECTED, SS_ISCONNECTING and SS_ISDISCONNECTING, instead of just SS_ISCONNECTED. That seams reasonable, so let's do the same.

Test Plan:
This issue was uncovered while writing tests for shutdown() in CloudABI:

41db4b88e0 Add an initial NUMA affinity/policy configuration for threads and processes.
This is based on work done by jeff@ and jhb@, as well as the numa.diff
patch that has been circulating when someone asks for first-touch NUMA
on -10 or -11.

* Introduce a simple set of VM policy and iterator types.
* tie the policy types into the vm_phys path for now, mirroring how
  the initial first-touch allocation work was enabled.
* add syscalls to control changing thread and process defaults.
* add a global NUMA VM domain policy.
* implement a simple cascade policy order - if a thread policy exists, use it;
  if a process policy exists, use it; use the default policy.
* processes inherit policies from their parent processes, threads inherit
  policies from their parent threads.
* add a simple tool (numactl) to query and modify default thread/process
  policities.
* add documentation for the new syscalls, for numa and for numactl.
* re-enable first touch NUMA again by default, as now policies can be
  set in a variety of methods.

This is only relevant for very specific workloads.

This doesn't pretend to be a final NUMA solution.

The previous defaults in -HEAD (with MAXMEMDOM set) can be achieved by
'sysctl vm.default_policy=rr'.

This is only relevant if MAXMEMDOM is set to something other than 1.
Ie, if you're using GENERIC or a modified kernel with non-NUMA, then
this is a glorified no-op for you.

Thank you to Norse Corp for giving me access to rather large
(for FreeBSD!) NUMA machines in order to develop and verify this.

Thank you to Dell for providing me with dual socket sandybridge
and westmere v3 hardware to do NUMA development with.

Thank you to Scott Long at Netflix for providing me with access
to the two-socket, four-domain haswell v3 hardware.

Thank you to Peter Holm for running the stress testing suite
against the NUMA branch during various stages of development!

Tested:

* MIPS (regression testing; non-NUMA)
* i386 (regression testing; non-NUMA GENERIC)
* amd64 (regression testing; non-NUMA GENERIC)
* westmere, 2 socket (thankyou norse!)
* sandy bridge, 2 socket (thankyou dell!)
* ivy bridge, 2 socket (thankyou norse!)
* westmere-EX, 4 socket / 1TB RAM (thankyou norse!)
* haswell, 2 socket (thankyou norse!)
* haswell v3, 2 socket (thankyou dell)
* haswell v3, 2x18 core (thankyou scott long / netflix!)

* Peter Holm ran a stress test suite on this work and found one
  issue, but has not been able to verify it (it doesn't look NUMA
  related, and he only saw it once over many testing runs.)

* I've tested bhyve instances running in fixed NUMA domains and cpusets;
  all seems to work correctly.

Verified:

* intel-pcm - pcm-numa.x and pcm-memory.x, whilst selecting different
  NUMA policies for processes under test.

Review:

This was reviewed through phabricator (https://reviews.freebsd.org/D2559)
as well as privately and via emails to freebsd-arch@.  The git history
with specific attributes is available at https://github.com/erikarn/freebsd/
in the NUMA branch (https://github.com/erikarn/freebsd/compare/local/adrian_numa_policy).

This has been reviewed by a number of people (stas, rpaulo, kib, ngie,
wblock) but not achieved a clear consensus.  My hope is that with further
exposure and testing more functionality can be implemented and evaluated.

Notes:

* The VM doesn't handle unbalanced domains very well, and if you have an overly
  unbalanced memory setup whilst under high memory pressure, VM page allocation
  may fail leading to a kernel panic.  This was a problem in the past, but it's
  much more easily triggered now with these tools.

* This work only controls the path through vm_phys; it doesn't yet strongly/predictably
  affect contigmalloc, KVA placement, UMA, etc.  So, driver placement of memory
  isn't really guaranteed in any way.  That's next on my plate.

temporary file is created and then a rename() call move it to official file.
This operation didn't have any check to make sure data was written to disk
and if a power cycle happens system could end up with a 0 length passwd

The following changes were made to protect passwd and group operations:

* lib/libutil/gr_util.c:
 - Replace mkstemp() by mkostemp() with O_SYNC flag to create temp file
 - After rename(), fsync() call on directory for faster result

* lib/libutil/pw_util.c

 - After rename(), fsync() call on directory for faster result

* lib/libutil/pw_util.3

qemu usermode emulation have both been updated for the new ABI.

This fixes clang failures, and most likely other crashes.

e419539610 Fix a regression in "movs" emulation after r284539. The regression was caused
due to a change in behavior of the 'vm_map_gpa()'.

Prior to r284539 if 'vm_map_gpa()' was called to map an address range in the
guest MMIO region then it would return NULL. This was used by the "movs"
emulation to detect if the 'src' or 'dst' operand was in MMIO space.

Post r284539 'vm_map_gpa()' started returning a non-NULL pointer even when
mapping the guest MMIO region.

Fix this by returning non-NULL only if [gaddr, gaddr+len) is entirely
within the 'lowmem' or 'highmem' regions and NULL otherwise.

8c70d6c7af Restructure memory allocation in bhyve to support "devmem".
devmem is used to represent MMIO devices like the boot ROM or a VESA framebuffer
where doing a trap-and-emulate for every access is impractical. devmem is a
hybrid of system memory (sysmem) and emulated device models.

devmem is mapped in the guest address space via nested page tables similar
to sysmem. However the address range where devmem is mapped may be changed
by the guest at runtime (e.g. by reprogramming a PCI BAR). Also devmem is
usually mapped RO or RW as compared to RWX mappings for sysmem.

Each devmem segment is named (e.g. "bootrom") and this name is used to
create a device node for the devmem segment (e.g. /dev/vmm/testvm.bootrom).
The device node supports mmap(2) and this decouples the host mapping of
devmem from its mapping in the guest address space (which can change).

aec8808588 Add support for reading MAM attributes to camcontrol(8) and libcam(3).
MAM is Medium Auxiliary Memory and is most commonly found as flash
chips on tapes.

This includes support for reading attributes and decoding most
known attributes, but does not yet include support for writing
attributes or reporting attributes in XML format.

libsbuf/Makefile:
	Add subr_prf.c for the new sbuf_hexdump() function.  This
	function is essentially the same function.

libsbuf/Symbol.map:
	Add a new shared library minor version, and include the
	sbuf_hexdump() function.

libsbuf/Version.def:
	Add version 1.4 of the libsbuf library.

libutil/hexdump.3:
	Document sbuf_hexdump() alongside hexdump(3), since it is
	essentially the same function.

camcontrol/Makefile:
	Add attrib.c.

camcontrol/attrib.c:
	Implementation of READ ATTRIBUTE support for camcontrol(8).

camcontrol/camcontrol.8:
	Document the new 'camcontrol attrib' subcommand.

camcontrol/camcontrol.c:
	Add the new 'camcontrol attrib' subcommand.

camcontrol/camcontrol.h:
	Add a function prototype for scsiattrib().

share/man/man9/sbuf.9:
	Document the existence of sbuf_hexdump() and point users to
	the hexdump(3) man page for more details.

sys/cam/scsi/scsi_all.c:
	Add a table of known attributes, text descriptions and
	handler functions.

	Add a new scsi_attrib_sbuf() function along with a number
	of other related functions that help decode attributes.

	scsi_attrib_ascii_sbuf() decodes ASCII format attributes.

	scsi_attrib_int_sbuf() decodes binary format attributes, and
	will pass them off to scsi_attrib_hexdump_sbuf() if they're
	bigger than 8 bytes.

	scsi_attrib_vendser_sbuf() decodes the vendor and drive
	serial number attribute.

	scsi_attrib_volcoh_sbuf() decodes the Volume Coherency
	Information attribute that LTFS writes out.

sys/cam/scsi/scsi_all.h:
	Add a number of attribute-related structure definitions and
	other defines.

	Add function prototypes for all of the functions added in
	scsi_all.c.

sys/kern/subr_prf.c:
	Add a new function, sbuf_hexdump().  This is the same as
	the existing hexdump(9) function, except that it puts the
	result in an sbuf.

	This also changes subr_prf.c so that it can be compiled in
	userland for includsion in libsbuf.

	We should work to change this so that the kernel hexdump
	implementation is a wrapper around sbuf_hexdump() with a
	statically allocated sbuf with a drain.  That will require
	a drain function that goes to the kernel printf() buffer
	that can take a non-NUL terminated string as input.
	That is because an sbuf isn't NUL-terminated until it is
	finished, and we don't want to finish it while we're still
	using it.

	We should also work to consolidate the userland hexdump and
	kernel hexdump implemenatations, which are currently
	separate.  This would also mean making applications that
	currently link in libutil link in libsbuf.

sys/sys/sbuf.h:
	Add the prototype for sbuf_hexdump(), and add another copy
	of the hexdump flag values if they aren't already defined.

	Ideally the flags should be defined in one place but the
	implemenation makes it difficult to do properly.  (See
	above.)
