t_time_arith: New test for timer calculations.

This will facilitate fixing various problems in the arithmetic to
determine, given an itimer's scheduled time (it_value) and periodic
interval (it_interval) along with the current time of actual expiry
(now), what time the itimer should be rescheduled for (next, new
value of it_timer) on the same clock.

Later we can also put tests for other functions like tvtohz here, and
make them test many different values of hz/tick.

XXX Not 100% sure about all of these cases -- there is some room for
reasonable discussion about what the right answer is. But we have
unquestionably implemented the wrong thing for many of these cases,
even if the answers this test checks for may not be quite right yet.

A driver for the MCP-2221 / 2221A multi-io chip. This is a USB to
UART / GPIO / I2C multi-io chip probably based upon a programmed PIC.
The end result is that simple gpio and i2c can exist on any system
that provides a USB port. This is everything from a RPI to a
Virtualbox VM.


o The UART presents itself as a umodem(4) device and pretty much works
as one would expect.

o There are 4 simple GPIO pins with multiple functions that attach to
gpio(4). Support for basic GPIO input and output exists with gpioctl,
the ADC, DAC and clock pulse functions exist as ALT functions. For
the ADC and DAC /dev/ devices are provided such that simple reads and
writes interact with the ADC and DAC. The IRQ function on pin GP1 and
bit banging the GPIO with gpiopps(4) and gpioow(4) are not really
supported. The short answer is that a spin lock is held while trying
to do USB transfers and that isn't allowed.

o There is a simple I2C engine that attaches to iic(4). This mostly
works as expected, except that a READ without STOP is not supported by
the engine which causes problems for some drivers. Most drivers do
not seem to use READ without STOP and seem to work as expected.
Support for changing the I2C speed is not supported, but nothing much
really does that.

o A userland utility called umcpmioctl(8) is provided that allows the
query of the status of the chip and allows for the query of the flash
memory and the setting of some of the flash memory parameters mostly
related to gpio. This utility interacts with a control device in
/dev/. The flash memory contents is copied to the sram on boot up of
the chip and can be used to adjust how the chip sets up the gpio pins,
among other things. Support for setting or entering the chip password
is not provided.

o A number of sysctls are provided to mess with various settings.
These are detailed in the man page.


While not perfect, the chip is reasonable, cheap, and has at least one
vendor making a breakout board. It is also one of the only ones in
this space that has enough documentation to write a driver.

Support for a related chip, the MCP-2210, which provides SPI and GPIO
may exist some day as the programming interface is very simular.

Add a test for clock_nanotime() [ PR kern/58733 ]

Add a t_nanosleep test to the kernel tests, to (to a limited extent)
validate its functionality.

Initially this concentrates on the issue from PR kern/58733
where if a process paused in nanosleep() is stopped, and then
continued, and if it is using TIMER_ABSTIME, the call will
return prematurely, but indicating success.

There are (currently) 4 test cases, to test all 4 possibilities
using CLOCK_MONOTONIC and CLOCK_REALTIME (if someone wants to
add any other clocks that make sense, that should be easy) and
TIMER_ABSTIME and TIMER_RELTIME.

Currently both TIMER_ABSTIME tests fail (the TIMER_RELTIME
tests pass). When the kernel bug is fixed, the ABSTIME
tests should be fixed along with it.

These tests are currently somewhat crude, and I'm not sure
how well they will work on a qemu test system (they work as
expected on bare metal).

arc4random(3): Add automatic tests.

This verifies that:
- arc4random zeroes its state and reseeds itself on fork
- arc4random reseeds itself on entropy consolidation (e.g., VM clone)
- arc4random falls back to global state if it can't allocate local
state because address space limits cause mmap to fail

NOTE: This adds a new libc symbol __arc4random_global, but it's in
the reserved namespace and only used by t_arc4random, so no libc
minor bump.

Revert the duplication of compat set lists; do it another way.

Revert the duplication of compat set lists; do it another way.

1. Restore the compatdir and compatfile tags in base and debug.

=> compatdir marks directories that should have per-ABI compat
subdirectories, like /usr/lib having /usr/lib/o32 and
/usr/lib/64 on mips64.

=> compatfile marks files that have per-ABI versions in the
nearest compatdir, like /usr/lib/o32/libc.so.12.221.

This is the mechanism we use to avoid duplicating every library
that has a compat version in multiple set lists.

2. Teach sets.subr to split the compatdir and compatfile entries out
into separate sets for base and debug.

The mechanism is to internally use:

- a new tag `omitcompat' when processing base and debug, so we
don't generate the per-ABI compat directories or per-ABI compat
files under them;

- a new tag `takecompat=${ABI}' when processing base32/64 and
debug32/64, so we _do_ generate the per-ABI compat directories
for ${ABI}.

=> On, e.g., mips64, base32 uses `takecompat=o32' and base64
uses `takecompat=64'.

=> On, e.g., aarch64, base32 uses
`takecompat=eabi,takecompat=eabihf', and there is no base64.

3. Record in sets.subr the list of `32' and `64' architectures for
each port.

This is maybe not the right place to put it, but it's also not
clear that we want to keep exactly this division -- maybe it would
be more sensible to just have per-ABI , e.g.:

(aarch64) base-eabi, base-eabihf
(amd64) base-i386
(mips64) base-o32, base-64
(mipsn64) base-o32, base-n32

But I'll leave cleaning that up for another day.

4. Adjust some sets. Mostly this commit shouldn't change what file
go in what sets, but, e.g., on mips64, the following move from
base32 to base64 as part of this change, which I think is
appropriate:

- /lib/64
- /libexec/ld.elf_so-64
- /usr/lib/64
- /usr/libdata/debug/lib/64
- /usr/libdata/debug/usr/lib/64
- /usr/libexec/ld.elf_so-64

TBD: Remove ./lib and ./usr/lib from debug/mi; they're already in
base/mi. Maybe move ./usr/libdata/debug to from base/mi to debug/mi.
