Implement battery management sysctl.  This will provide a set of sysctls
to control the charging of laptop batteries:

* hw.battery.chargemode (int)

  -1: force discharge
   0: inhibit charge
   1: auto

In auto mode charging may be controlled by:

* hw.battery.chargestop (int)

  Percentage (0-100) of last full capacity at which the battery should
  stop charging.

* hw.battery.chargestart (int)

  Percentage (0-100) of last full capacity at which the battery should
  start charging.

The idea is that with

  hw.battery.chargemode=1
  hw.battery.chargestop=80
  hw.battery.chargestart=75

the battery would be kept charged within the range between 75% and 80%.

Allowable settings and some details of the behavior may differ between
hardware implementations.

Committing this early to easy testing of further diffs that implement this
functionality in acpithinkpad(4) and aplsmc(4).

clockintr(9): initial commit

clockintr(9) is a machine-independent clock interrupt scheduler.  It
emulates most of what the machine-dependent clock interrupt code is
doing on every platform.  Every CPU has a work schedule based on the
system uptime clock.  For now, every CPU has a hardclock(9) and a
statclock().  If schedhz is set, every CPU has a schedclock(), too.

This commit only contains the MI pieces.  All code is conditionally
compiled with __HAVE_CLOCKINTR.  This commit changes no behavior yet.

At a high level, clockintr(9) is configured and used as follows:

1. During boot, the primary CPU calls clockintr_init(9).  Global state
   is initialized.
2. Primary CPU calls clockintr_cpu_init(9).  Local, per-CPU state is
   initialized.  An "intrclock" struct may be installed, too.
3. Secondary CPUs call clockintr_cpu_init(9) to initialize their
   local state.
4. All CPUs repeatedly call clockintr_dispatch(9) from the MD clock
   interrupt handler.  The CPUs complete work and rearm their local
   interrupt clock, if any, during the dispatch.
5. Repeat step (4) until the system shuts down, suspends, or hibernates.
6. During resume, the primary CPU calls inittodr(9) and advances the
   system uptime.
7. Go to step (2).  This time around, clockintr_cpu_init(9) also
   advances the work schedule on the calling CPU to skip events that
   expired during suspend.  This prevents a "thundering herd" of
   useless work during the first clock interrupt.

In the long term, we need an MI clock interrupt scheduler in order to
(1) provide control over the clock interrupt to MI subsystems like
timeout(9) and dt(4) to improve their accuracy, (2) provide drivers
like acpicpu(4) a means for slowing or stopping the clock interrupt on
idle CPUs to conserve power, and (3) reduce the amount of duplicated
code in the MD clock interrupt code.

Before we can do any of that, though, we need to switch every platform
over to using clockintr(9) and do some cleanup.

discussion at a2k19 on the subject.  Lots of design input from
kettenis@.  Early versions reviewed by kettenis@ and mlarkin@.

Change hw.perfpolicy=auto by default, at startup.  If the system has AC
power connected (default is yes when no driver differentiates) then default
to 100% performance. On battery, use the existing auto algorithm (which is
admittedly somewhat unrefined).
This change overrides the system/BIOS speed and puts OpenBSD in control.
As this happens very early during boot, besides speedups in all usage usage
patterns, some surprises: unhibernate and sysupgrade times are cut in half.
note: on a few architectures, the setperf fn pointer is changed late, and
thus the auto algorithm stops timeing out.  kettenis and i will look for
a solution.

Rearrange the implementation of bounded sysctl.  The primitive

the 4.4BSD implementation.  Then sysctl_int_bounded() builds the
magic for range checks on top.  sysctl_bounded_arr() is a wrapper
around it to support multiple variables.
Introduce macros that describe the meaning of the magic boundary
values.  Use these macros in obvious places.

Remove unused debug_syncprt, improve debug sysctl handling

"syncprt" is unused since kern/vfs_syscalls.c r1.147 from 2008.

Adding new debug sysctls is a bit opaque and looking at kern/kern_sysctl.c
the only visible difference between used and stub ctldebug structs in the
debugvars[] array is their extern keyword, indicating that it is defined
elsewhere.

sys/sysctl.h declares all debugN members as extern upfront, but these
declarations are not needed.

Remove the unused debug sysctl, rename the only remaining one to something
meaningful and remove forward declarations from /sys/sysctl.h;  this way,
adding new debug sysctls is a matter of adding extern and coming up with a
name, which is nicer to read on its own and better to grep for.

Move sysctl(2) CTL_DEBUG from DEBUG to new DEBUG_SYSCTL

Adding "debug.my-knob" sysctls is really helpful to select different
code paths and/or log on demand during runtime without recompile,
but as this code is under DEBUG, lots of other noise comes with it
which is often undesired, at least when looking at specific subsystems
only.

Adding globals to the kernel and breaking into DDB to change them helps,
but that does not work over SSH, hence the need for debug sysctls.

Introduces DEBUG_SYSCTL to make use of the "debug" MIB without the rest of
DEBUG; it's DEBUG_SYSCTL and not SYSCTL_DEBUG because it's not a general
option for all of sysctl(2).

sysctl(2): add kern.utc_offset: successor to the DST/TIMEZONE options(4)

The DST and TIMEZONE options(4) are incompatible with KARL, so we need
some other way to compensate for an RTC running with a known offset.

Enter kern.utc_offset, an offset in minutes East of UTC.  TIMEZONE has
always been minutes West, but this is inconsistent with how everyone
else talks about timezones, hence the flip.

TIMEZONE has the advantage of being compiled into the binary.  Our new
sysctl(2) has no such luck, so it needs to be set as early as possible
in boot, from sysctl.conf(5), so we can correct the kernel clock from
the RTC's local time to UTC before daemons like ntpd(8) and cron(8)
start.  To encourage this, kern.utc_offset is made immutable after the
securelevel(7) is raised to 1.

Revert to using the SCHED_LOCK() to protect time accounting.

It currently creates a lock ordering problem because SCHED_LOCK() is taken
by hardclock().  That means the "priorities" of a thread should be moved
out of the SCHED_LOCK() first in order to make progress.

delivered it to the main thread.  This does not conform to POSIX.

Add lock stack trace saving for witness(4).

Add new KERN_CPUSTATS sysctl(2) so we can identify offline CPUs.

Because of hw.smt we need a way to determine whether a given CPU is "online"
or "offline" from userspace.  KERN_CPTIME2 is an array, and so cannot be
cleanly extended for this purpose, so add a new sysctl(2) KERN_CPUSTATS
with an extensible struct.  At the moment it's just KERN_CPTIME2 with a
flags member, but it can grow as needed.

KERN_CPUSTATS appears to have been defined by BSDi long ago, but there are
few (if any) packages in the wild still using the symbol so breakage in ports
should be near zero.  No other system inherited the symbol from BSDi, either.

Then, use the new sysctl(2) in systat(1) and top(1):

  - systat(1) draws placeholder marks ('-') instead of percentages for
    offline CPUs in the cpu view.

  - systat(1) omits offline CPU ticks when drawing the "big bar" in
    the vmstat view.  The upshot is that the bar isn't half idle when
    half your logical CPUs are disabled.

  - top(1) does not draw lines for offline CPUs; if CPUs toggle on or
    offline in interactive mode we redraw the display to expand/reduce
    space for the new/missing CPUs.  This is consistent with what some
    top(1) implementations do on Linux.

  - top(1) omits offline CPUs from the totals when CPU totals are
    combined into a single line (the '-1' flag).

Add hw.ncpuonline to count the number of online CPUs.

The introduction of hw.smt means that logical CPUs can be disabled
after boot and prior to suspend/resume.  If hw.smt=0 (the default),
there needs to be a way to count the number of hardware threads
available on the system at any given time.

So, import HW_NCPUONLINE/hw.ncpuonline from NetBSD and document it.
hw.ncpu becomes equal to the number of CPUs given to sched_init_cpu()
during boot, while hw.ncpuonline is equal to the number of CPUs available
to the scheduler in the cpuset "sched_all_cpus". Set_SC_NPROCESSORS_ONLN
equal to this new sysctl and keep _SC_NPROCESSORS_CONF equal to hw.ncpu.

This is preferable to adding a new sysctl to count the number of
configured CPUs and keeping hw.ncpu equal to the number of online
CPUs because such a change would break software in the ecosystem
that relies on HW_NCPU/hw.ncpu to measure CPU usage and the like.
Such software in base includes top(1), systat(1), and snmpd(8),
and perhaps others.

We don't need additional locking to count the cardinality of a cpuset
in this case because the only interfaces that can modify said cardinality
are sysctl(2) and ioctl(2), both of which are under the KERNEL_LOCK.

Software using HW_NCPU/hw.ncpu to determine optimal parallism will need
to be updated to use HW_NCPUONLINE/hw.ncpuonline.  Until then, such software
may perform suboptimally.  However, most changes will be similar to the
change included here for libcxx's std::thread:hardware_concurrency():
using HW_NCPUONLINE in lieu of HW_NCPU should be sufficient for determining
optimal parallelism for most software if the change to _SC_NPROCESSORS_ONLN
is insufficient.

Prompted by deraadt. Discussed at length with kettenis, deraadt, and sthen.

SMT (Simultanious Multi Threading) implementations typically share
TLBs and L1 caches between threads.  This can make cache timing
attacks a lot easier and we strongly suspect that this will make
several spectre-class bugs exploitable.  Especially on Intel's SMT
implementation which is better known as Hypter-threading.  We really
should not run different security domains on different processor
threads of the same core.  Unfortunately changing our scheduler to
take this into account is far from trivial.  Since many modern
machines no longer provide the ability to disable Hyper-threading in
the BIOS setup, provide a way to disable the use of additional
processor threads in our scheduler.  And since we suspect there are
serious risks, we disable them by default.  This can be controlled
through a new hw.smt sysctl.  For now this only works on Intel CPUs
when running OpenBSD/amd64.  But we're planning to extend this feature
to CPUs from other vendors and other hardware architectures.

Note that SMT doesn't necessarily have a posive effect on performance;
it highly depends on the workload.  In all likelyhood it will actually
slow down most workloads if you have a CPU with more than two cores.

Introduce PS_NOBROADCASTKILL a process flag that excludes processes from
receiving broadcast signals (kill -1). The flag can be set via a new
sysctl KERN_PROC_NOBROADCASTKILL. This will be used by iscsid to survive
the mass killing by init(8) when terminating multi-user operations.

Move from struct proc to process the reference-count-holding pointers
to the process's vmspace and filedescs.  struct proc continues to
keep copies of the pointers, copying them on fork, clearing them
on exit, and (for vmspace) refreshing on exec.
Also, make uvm_swapout_threads() thread aware, eliminating p_swtime

that function is going to get more an more broken as we move stuff

code copying, put the common logic of filling in a kinfo_proc2
structure into a macro FILL_KPROC2() in <sys/sysctl.h> for use from
both the kernel and user-space.  This also hides the KERN_PROC

stay

Back out all the buffer cache changes I committed during c2k9. This reverts three
commits:

1) The sysctl allowing bufcachepercent to be changed at boot time.
2) The change moving the buffer cache hash chains to a red-black tree
3) The dynamic buffer cache (Which depended on the earlier too).

ok on the backout from marco and todd

This touches only MI code, and adds new time keeping code.  The
code is all conditionalized on __HAVE_TIMECOUNTER, and not
enabled on any platforms.

adjtime(2) support exists, courtesy of nordin@, sysctl(2) support
and a concept of quality for each time source attached exists.

High quality time sources exists for PIIX4 ACPI timer as well as
some AMD power management chips.  This will have to be redone
once we actually add ACPI support (at that time we need to use
the ACPI interfaces to get at these clocks).

Make SysV-style shared memory and semaphore limits sysctl'able.
Instead of allocating a static amount of memory for the data
structures via valloc() in allocsys(), allocate things dynamically
using pool(9) when possible and malloc(9) when not.  The various
members of struct seminfo and struct shminfo are in kern.seminfo
and kern.shminfo respectively (not all members of kern.seminfo are
changable).

The data structures used still leave something to be desired but
things are not made worse in that respect by this commit.

Add a possibility to add a random offset to the stack on exec. This makes
it slightly harder to write generic buffer overflows. This doesn't really
give any real security, but it raises the bar for script-kiddies and it's
really cheap.

The range of the random offsets is controlled by the sysctl
kern.stackgap_random (must be a power of 2).

This is disabled by default right now, but we'll set it to a reasonable value
(1024?) soon, after some more testing.
