15d4459cb2 scsi.4: Document serial numbers
You can wire da, ada and nda device units to serial numbers. sdda cannot
be wired like this because SD and MMC cards lack serial numbers (or at
the very least CAMMMC does not query or retain them).

bd82711aff cam: Remove trailing spaces from serial numbers too
The SanDisk SD8SB8U1 and likely others pad their serial number with
spaces on the end rather than the start (at least when connected to a
SAS3008). This makes them difficult to wire unit numbers to with the
serial because you have to specify the trailing spaces. Instead, strip
out the trailing spaces.

We already strip leading spaces both here. In addition, when glabel
creates the devfs device nodes, leading and trailing spaces are removed
already (so there will be no change there either).

577f9aa266 cam_periph: Add ability to wire units to a serial number
For scsi, ata and nvme, at least, we read a serial number from the
device (if the device supports it, some scsi drives do not) and record
it during the *_xpt probe device state machine before it posts the
AC_FOUND_DEVICE async event. For mmc, no serial number is ever
retrieved, so it's always NULL. Add the ability to match this serial
number during device wiring.

This mechanism is competely optional, and often times using a label
and/or some other attribute of the device is easier. However, other
times wiring a unit to a serial number simplifies management as most
monitoring tools require the *daX device and having it stable from boot
to boot helps with data continuity. It can be especially helpful for
nvme where no other means exists to reliably tie a ndaX device to an
underlying nvme drive and namespace.

A similar mechanism exists in Linux to mange device unit numbers with
udev.

710a519ebb cam_periph: fix bug in camperiphunitnext logic
If we assigned just a lun as a wired unit (something that camperiphunit

next unit number. Add lun so the code matches the comments that we have
to skip all the same criteria that camperiphunit uses to select wired

When scanning the resources that are wired for this driver, skip any
that whose number doesn't match newunit. They aren't relevant. Switch to

00f79c97a4 cam_periph: Remove vestigial "scbus" comparison
The code in camperiphunit rejects "scbus" as an 'at' location that would
allow any other wiring to use that unit number. Yet in
camperiphunitnext, if we have a no target and the 'at' location of
'scbus' it would be excluded on the basis that it's a wiring
cadidate. This is improper and appears to be a hold-over of the
pre-hints / pre-newbus config system, so remove it.

517e52b6c2 awk: Move to using two sets of tests
Upstream one-true-awk has two sets of tests. These are in addition to
NetBSD's tests we're using. The 'bugs-fixed' tests from upstream are
ready to use as-is (more or less). However, the 'tests' from upstream
are not, so for now we'll just use the netbsd and bugs-fixed tests.
They provide an OK workout and are better than nothing, though the tests
themselves are for specific esoteric things.

The upstream bugs-fixed tests are *ALMOST* a drop in. However, 3 test
for errors and the upstream test jig mashes stdout and stderr together,
which atf doesn't do, so make a tiny tweak to the upstream tests that I
hope to upstream. Plus upstream has ../a.out: instead of awk: in the
output. Not sure how to deal with this yet, so I've not proposed
anything upstream and have changed the test locally.

In addition, the system-status.awk test is not suitable to run in ATF.
It wants to force sh to dump core, but kyua doesn't seem to allow that
sometimes so the test will fail or pass based on whether or not a core
dump can be created. Since it's unstable, remove it.

This required moving the netbsd tests to a new direcotry, so update
mtree files as well. The change is useless for 'make check' without it.

046e2d5db1 Implementations of cexpl()
The change implements cexpl() for both ld80 and ld128 architectures.
Testing was done on x86_64 and aarch64 systems.

Along the way sincos[fl]() use an optimization that reduces the argument
to being done one rather than twice.  This optimization actually pointed
to a bug in the ld128 version of sincosl(), which is now fixed.  In
addition, the minmax polynomial coefficients for sincosl() have been
updated.

A concise log of the file-by-file changes follows.

* include/complex.h:
  . Add a prototype for cexpl().

* lib/msun/Makefile:
  . Add s_cexpl.c to the build.
  . Setup a link for cexpl.3 to cexp.3.

* lib/msun/Symbol.map:
  . Expose cexpl symbol in libm shared library.

* lib/msun/ld128/s_cexpl.c:
  * Implementation of cexpl() for 128-bit long double architectures.
    Tested on an aarch64 system.

* lib/msun/ld80/s_cexpl.c:
  * Implementation of cexpl() for Intel 80-bit long double.

* lib/msun/man/cexp.3:
  . Document cexpl().

* lib/msun/man/complex.3:
  . Add a BUGS section about cpow[fl].

* lib/msun/src/s_cexp.c:
  . Include float.h for weak references on 53-bit long double targets.
  . Use sincos() to reduce argument reduction cost.

* lib/msun/src/s_cexpf.c:
  . Use sincosf() to reduce argument reduction cost.

* lib/msun/src/k_sincosl.h:
  . Catch up with the new minmax polynomial coefficients for the kernel for
    the 128-bit cosl() implementation.
  . BUG FIX: *cs was used where *sn should have been.  This means that sinl()
    was no computed correctly when iy != 0.

* lib/msun/src/s_cosl.c:
  . Include fpmath.h to get access to IEEEl2bits.
  . Replace M_PI_4 with pio4,  a 64-bit or 113-bit approximation for pi / 4.

8b57ee7e01 sdhci_fsl_fdt: Provide more accurate clk calculation
SDHCI controllers found in the QorIQ SoCs offer improved accuracy of
the clock frequency selection, compared to the SDHCI standard. Frequency
selection is performed using two divider registers, named prescaler and
divisor, according to the following formula:
frequency = base clock / (prescaler * divisor), where prescaler can be
bypassed (set to 1) and divisor permitted to take odd values.

Rather than depend on clock division precalculated by sdhci core, make
use of this property of the divider registers and achieve frequencies
closer to the ones requested.

80e5955b08 nfscl: Fix NFSv4.1/4.2 pnfs mounts using nconnect
When a mount with the "pnfs" and "nconnect" options specified
does an I/O operation, it erroneously uses a TCP connection
to the MDS when it is meant to be a DS operation and, as such,
needs to use a TCP connection to the DS.  This patch fixes this.

When the "pnfs" and "nconnect" options are specified for a
NFSv4.1/4.2 mount, there probably should be N connections
established to each DS for I/O RPCs.  This is a fair amount
of work and may be done in a future commit.

This problem was found during a recent IETF NFSv4 working
group testing event.

e9a994639b ssh: enable FIDO/U2F keys
Description of FIDO/U2F support (from OpenSSH 8.2 release notes,
https://www.openssh.com/txt/release-8.2):

  This release adds support for FIDO/U2F hardware authenticators to
  OpenSSH. U2F/FIDO are open standards for inexpensive two-factor
  authentication hardware that are widely used for website
  authentication.  In OpenSSH FIDO devices are supported by new public
  key types "ecdsa-sk" and "ed25519-sk", along with corresponding
  certificate types.

  ssh-keygen(1) may be used to generate a FIDO token-backed key, after
  which they may be used much like any other key type supported by
  OpenSSH, so long as the hardware token is attached when the keys are
  used. FIDO tokens also generally require the user explicitly
  authorise operations by touching or tapping them.

  Generating a FIDO key requires the token be attached, and will
  usually require the user tap the token to confirm the operation:

    $ ssh-keygen -t ecdsa-sk -f ~/.ssh/id_ecdsa_sk
    Generating public/private ecdsa-sk key pair.
    You may need to touch your security key to authorize key generation.
    Enter file in which to save the key (/home/djm/.ssh/id_ecdsa_sk):
    Enter passphrase (empty for no passphrase):
    Enter same passphrase again:
    Your identification has been saved in /home/djm/.ssh/id_ecdsa_sk
    Your public key has been saved in /home/djm/.ssh/id_ecdsa_sk.pub

  This will yield a public and private key-pair. The private key file
  should be useless to an attacker who does not have access to the
  physical token. After generation, this key may be used like any
  other supported key in OpenSSH and may be listed in authorized_keys,
  added to ssh-agent(1), etc. The only additional stipulation is that
  the FIDO token that the key belongs to must be attached when the key
  is used.

To enable FIDO/U2F support, this change regenerates ssh_namespace.h,
adds ssh-sk-helper, and sets ENABLE_SK_INTERNAL (unless building
WITHOUT_USB).

devd integration is not included in this change, and is under
investigation for the base system.  In the interim the security/u2f-devd
port can be installed to provide appropriate devd rules.

d3514c2942 ipq401x: add MP core start-up path for the CPU regulator/clock gate used
This code implements the "kpssv2" flavour of CPU regulator/clock gating
in Linux.  It's used by at least the ipq4018/4019 to power on and off
CPU cores.

This is based on the Linux implementation - the register definitions
and values are from Linux and I've reverse engineered the sequencing
requirements.

The MP bring-up is:

* set cold boot address via an SCM call - this is the address used
  by the bootloader/TZ firmware to jump to when the CPUs boot

* power down the LDO feeding the CPU core and wait for it to settle

* program in the right set of LDO and power tree configuration for
  the CPU regulator to power up the core.  Unfortunately these are
  magic numbers that I've not found documented anywhere.

* (I think) power up the shared L2 cache connect if it isn't.

* Clamp the power into the core down; put the core into reset

* Unclamp the power rail; release reset; and then set the core to boot.

The MP core will then boot the bootloader/TZ firmware and then
will wait until an incoming interrupt kicks it to start @ mpentry.

Tested:

* IPQ4019, 4 CPUs

890cae1977 fsck_msdosfs: truncate directory entry when the head pointer is invalid.
As far as we know, there is no FAT implementation that supported hard
links, and our msdosfs driver assumed one cluster chain is only
referenced by one directory entry and clears it out when the file is
deleted.  On the other hand, the current code would proceed with
checkchain() when the directory entry's head cluster is a valid numbered
cluster without checking if it was a valid head node of a cluster chain.

So if the cluster do not being a chain (e.g. CLUST_FREE, CLUST_BAD),
or was already referenced by another directory entry, this would
trigger an assertion in check_chain() at a later time.

Fix this by giving the user an option to truncate the directory entry
when the head cluster is an invalid cluster, an visited head node,
or not a head node.

ba48d52ca6 vt: Fix frequency calcuation for bell
386BSD provided a MD function sysbeep. This took two arguments (pitch
and period). Pitch was jammed into the PIT's divisor directly (which
means the argument was expected to sound a tone at '1193182 / pitch'
Hz). FreeBSD inherited this interface.

In commit e465985885 (svn 177642, Mar 26 2008), phk changed this
function to take a tone to sound in hz. He converted all in-tree
instances of 1193182 / hz to just hz (and kept the few misguided folks
that passed hz directly unchanged -- this was part of what motivated the
change). He converted the places where we pre-computed the 8254 divisor
from being pitch to 1193182 / pitch (since that converts the divisor to
the frequency and the interfaces that were exposed to userland exposed
it in these units in places, continuing the tradition inherited from SCO
System V/386 Unix in spots).

In 2009, Ed Shouten was contracted by the FreeBSD Foundation to write /
finish newcons. This work was done in perforce and was imported into
subversion in user/ed/newcons in revision 199072
(https://svnweb.freebsd.org/base?view=revision&revision=199072) which
was later imported into FreeBSD by ray@ (Aleksandr Rybalko).

From that earliest import into svn import to this date, we ring the bell
with:
      sysbeep(1193182 / VT_BELLPITCH, VT_BELLDURATION);
where VT_BELLPITCH was defined to be 800. This results in a bell
frequency of 1491Hz, more or less today. This is similar to the
frequency that syscons and pcvt used (1493Hz and 1500Hz respectively).
This in turn was inherited from 386BSD, it seems, which used the hard
coded value 0x31b which is 795 -> 1500Hz.

This '800' was intended to be the bell tone (eg 800Hz) and this
interface was one that wasn't converted. The most common terminal prior
to the rise of PCs was the VT100, which had an approximately 800Hz
bell. Ed Shouten has confirmed that the original intent was 800Hz and
changing this was overlooked after the change to -current was made.
This restors that original intent and makes the bell less obnoxious in
the process.

2533eca1c2 vt(4): Connect to teken's TP_SETBELLPD
Add the glue needed to listen to TP_SETBELLPD which teken uses to
inform its client drivers about the results of parsing
\e[=<pitch>;<duration>B. It converts these to a Hz value for the
tone/pitch of the bell and a duration in ms. There's some loss of
precision because <pitch> in the escape seuquence is defined to be
(1193182 / pitch) Hz and <duration> is in 10ms units. Also note that
kbdcontrol also parses 'off' but then doesn't send the proper escape
sequence, leading me to wonder if that's another bug since teken
appears to parse that sequence properly and I've added code here to
treat that as the same as quiet or disabled.

In general, Hz from 100 to 2000 is good. Outside that range is possible,
but even at 100Hz the square wave is starting to sound bad and above
2000Hz the speaker may not respond.

6b67753488 nfscl: Fix forced dismount from looping on commit
When a forced dismount is in progress, it is possible to
end up looping, retrying commits that fail.
This patch fixes the problem by pretending
that commits succeeded when a forced dismount is in prgress.

589aed00e3 sched: separate out schedinit_ap()
schedinit_ap() sets up an AP for a later call to sched_throw(NULL).

Currently, ULE sets up some pcpu bits and fixes the idlethread lock with
a call to sched_throw(NULL); this results in a window where curthread is
setup in platforms' init_secondary(), but it has the wrong td_lock.
Typical platform AP startup procedure looks something like:

- Setup curthread
- ... other stuff, including cpu_initclocks_ap()
- Signal smp_started
- sched_throw(NULL) to enter the scheduler

cpu_initclocks_ap() may have callouts to process (e.g., nvme) and
attempt to sched_add() for this AP, but this attempt fails because
of the noted violated assumption leading to locking heartburn in
sched_setpreempt().

Interrupts are still disabled until cpu_throw() so we're not really at
risk of being preempted -- just let the scheduler in on it a little
earlier as part of setting up curthread.
