d7ef92ffae CMSG_DATA.3: Fix formatting of printf escape sequences
Escape sequences like "\n" have to be escaped twice in examples in our
mdoc(7)-based manual pages in order to be displayed properly. The problem
is that otherwise they are interpreted by mdoc(7), which results in:

    printf("parent: received '%s'0, buf);

being shown to the user instead of:

    printf("parent: received '%s'\n", buf);

afc571b1a6 veloader use vectx API for kernel and modules
The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.

For doing an install via loader, avoiding the need to rewind
large files is critical.

This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform.  On a fast VM we see 6% improvement.

For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().

For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.

Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.

Now that we no longer have GCC 4.2.1 in the tree and can assume FreeBSD

unconditionally and retire the GPL dtc.

GPL dtc now has FreeBSD CI support via Cirrus-CI to help ensure it
continues to build/work on FreeBSD and is available in the ports tree
if needed.

The copy of (copyfree licensed) libfdt that we actually use is in
sys/contrib/libfdt so the extra copy under contrib/dtc/libfdt can be
removed along with the rest of the GPL dtc.

57f804675e remove GCC 4.2.1 build infrastructure
As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date.  At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).

GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825.  GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD.  It
does not support modern C and does not support arm64 or RISC-V.

Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.

So long, and thanks for all the fish.

eb834d9f1b Take LINKER_FREEBSD_VERSION from numerical field after dash
Summary:
With COMPILER_FREEBSD_VERSION, we use a numeric value that we bump each
time we make a change that requires re-bootstrapping, but with the
linker variant, we instead take the entire part after "FreeBSD", as in
this example version output:

LLD 9.0.1 (FreeBSD c1a0a213378a458fbea1a5c77b315c7dce08fd05-1300006) (compatible with GNU linkers)

E.g., LINKER_FREEBSD_VERSION is currently being set to
"c1a0a213378a458fbea1a5c77b315c7dce08fd05-1300006".  This means that
*any* new upstream lld version will cause re-bootstrapping.

We should only look at the numerical field we append after a dash
instead.  This review attempts to make it so.

The only thing I am not happy about is the post-processing of awk output
in Makefile.inc1.  I notice that our awk does not have gensub(), so it
can't substitute a numbered sub-regex with \1, \2, etc.  Suggestions
welcome. :)

294de6bbd6 Add _BIX (Battery Information Extended) object support.
ACPI Control Method Batteries have a _BIF and/or _BIX object which
provide static properties of the battery.  FreeBSD acpi_cmbat module
supported _BIF object only, which was deprecated as of ACPI 4.0.
_BIX is an extended version of _BIF defined in ACPI 4.0 or later.

As of writing, _BIX has two revisions.  One is in ACPI 4.0 (rev.0) and
another is in ACPI 6.0 (rev.1).  It seems that hardware vendors still
stick to _BIF only or _BIX rev.0 + _BIF for the maximum compatibility.
Microsoft requires _BIX rev.0 for Windows machines, so there are some
laptop machines with _BIX rev.0 only. In this case, FreeBSD does not
recognize the battery information.

After this change, the acpi_cmbat module gets battery information from
_BIX or _BIF object and internally uses _BIX rev.1 data structure as
the primary information store in the kernel.  ACPIIO_BATT_GET_BI[FX]
returns an acpi_bi[fx] structure built by using information obtained
from a _BIF or a _BIX object found on the system.  The revision number
field can be used to check which field is available.  The acpiconf(8)
utility will show additional information if _BIX is available.

Although ABIs of ACPIIO_BATT_* were changed, the existing APIs for
userland utilities are not changed and the backward-compatible ABIs
are provided.  This means that older versions of acpiconf(8) can also
work with the new kernel. The (union acpi_battery_ioctl_arg) was
padded to 256 byte long to avoid another ABI change in the future.
A _BIX object with its revision number >1 will be treated as
compatible with the rev.1 _BIX format.

604d0dd551 Use 0x5c for the scan code 0x7d.
Japanese keyboards traditionally use 0x5c for
both Japanese yen sign key and backslash key.
While a Japanese yen sign is depicted on the keytop,
most of Japanese expect that the scan code 0x7d gives
a backslash (0x5c), not a Japanese yen sign (0xa5).

This is because JIS X 0201 encoding (aka ISO/IEC 646-JA,
an extended version of ASCII which is very popular
in Japan) has Japanese yen sign at 0x5c and
no backslash.  On the other hand, ISO/IEC 8859-1
has Japanese yen sign at 0xa5.  This difference has
caused a confusion after Unicode became popular since
ISO/IEC 10646 adopted 8859-1 for the plane 0.

504613f246 Remove simple_httpd
simple_httpd was granted a reprieve from the picobsd removal based on having
some reported user; it turns out this user isn't actually using the version
in base and merging their changes would be difficult at this point, so the
version in base will simply continue to rot. Retire it now, it may make a
comeback to ports with the improved version.

No notice issued because its current visibility has only been for ~3
months, and a notice has been previously issued about picobsd removal.

43524989c5 hwpstate(4): Ignore CurPstateLimit by default
Add a sysctl knob to allow users to re-enable it, and document the knob and
default in cpufreq.4.  (While here, add a few unrelated updates to
cpufreq.4.)

It seems that the register value in some hardware simply reflects the
configured P-state.  This results in an inadvertent and unintended outcome
where the P-state can only walk down, and then the driver becomes "stuck" in
the slowest possible P-state.

The Linux driver never consults this register, so that's some evidence that
ignoring the contents are relatively harmless.

1c29da0279 Reimplement stack capture of running threads on i386 and amd64.
After r355784 the td_oncpu field is no longer synchronized by the thread
lock, so the stack capture interrupt cannot be delievered precisely.
Fix this using a loop which drops the thread lock and restarts if the
wrong thread was sampled from the stack capture interrupt handler.

Change the implementation to use a regular interrupt instead of an NMI.
Now that we drop the thread lock, there is no advantage to the latter.

Simplify the KPIs.  Remove stack_save_td_running() and add a return
value to stack_save_td().  On platforms that do not support stack
capture of running threads, stack_save_td() returns EOPNOTSUPP.  If the
target thread is running in user mode, stack_save_td() returns EBUSY.

FreeBSD 11 and newer assumes hard. 10 and earlier assumed softfp.  We have no
real support, at the moment, for soft. It's untested, though, if softfp still
works.

Add a note here since this is a whack-a-doodle combination relative to all other

softfp is likely to go away in the future because it was retained for people
using FreeBSD 10 + armv6 needing to transition more slowly from softfp -> hard
than the project. It likely is no longer needed, and may be getting in the
way of people needing 'soft' support.

It's not immediately clear by what mechanism loader(8) will be loading the
preloaded file. Specifically name-drop loader.conf(5) with a pointer to the
module loading section and a description of what the 'name' should look
like, because that certainly isn't clear from the loader.conf(5) standpoint.

The default loader.conf already has a pointer to md(4) where it appears and
the reference to loader.conf in the new version of this manpage should make
it more clear that this is where one should look for information.

This re-enables building the googletest suite by default on mips and instead
specifically doesn't build fusefs tests for mips+clang builds.  clang will
easily spent >= 1.5 hours compiling a single file due to a bug in
optimization (see LLVM PR 43263), so turn these off for now while that's
hashed out.

GCC builds are unaffected and build the fusefs tests as-is. Clang builds
only happen by early adopters attempting to hash out the remaining issues.

422d05da14 Add support for i2c bus mux hardware.
An i2c bus can be divided into segments which can be selectively connected
and disconnected from the main bus. This is usually done to enable using
multiple slave devices having the same address, by isolating the devices
onto separate bus segments, only one of which is connected to the main bus
at once.

There are several types of i2c bus muxes, which break down into two general
categories...

 - Muxes which are themselves i2c slaves. These devices respond to i2c
   commands on their upstream bus, and based on those commands, connect
   various downstream buses to the upstream. In newbus terms, they are both
   a child of an iicbus and the parent of one or more iicbus instances.
 - Muxes which are not i2c devices themselves. Such devices are part of the
   i2c bus electrically, but in newbus terms their parent is some other
   bus. The association with the upstream bus must be established by
   separate metadata (such as FDT data).

In both cases, the mux driver has one or more iicbus child instances
representing the downstream buses. The mux driver implements the iicbus_if
interface, as if it were an iichb host bridge/i2c controller driver. It
services the IO requests sent to it by forwarding them to the iicbus
instance representing the upstream bus, after electrically connecting the
upstream bus to the downstream bus that hosts the i2c slave device which
made the IO request.

The net effect is automatic mux switching which is transparent to slaves on
the downstream buses. They just do i2c IO they way they normally do, and the
bus is electrically connected for the duration of the IO and then idled when
it is complete.

The existing iicbus_if callback() method is enhanced so that the parameter
passed to it can be a struct which contains a device_t for the requesting
bus and slave devices. This change is done by adding a flag that indicates
the extra values are present, and making the flags field the first field of
a new args struct. If the flag is set, the iichb or mux driver can recast
the pointer-to-flags into a pointer-to-struct and access the extra
fields. Thus abi compatibility with older drivers is retained (but a mux
cannot exist on the bus with the older iicbus driver in use.)

A new set of core support routines exists in iicbus.c. This code will help
implement mux drivers for any type of mux hardware by supplying all the
boilerplate code that forwards IO requests upstream. It also has code for
parsing metadata and instantiating the child iicbus instances based on it.

Two new hardware mux drivers are added. The ltc430x driver supports the
LTC4305/4306 mux chips which are controlled via i2c commands. The
iic_gpiomux driver supports any mux hardware which is controlled by
manipulating the state of one or more gpio pins.  Test Plan

Tested locally using a variety of mux'd bus configurations involving both
ltc4305 and a homebrew gpio-controlled mux. Tested configurations included
cascaded muxes (unlikely in the real world, but useful to prove that 'it all
just works' in terms of the automatic switching and upstream forwarding of
IO requests).

srandom(9) is meaningless on SMP systems or any system with, say,

sequence of outputs on the basis of a specific srandom() seed because the
global state was shared by all kernel contexts.  As such, removing it is
literally indistinguishable to random(9) consumers (as compared with
retaining it).

Mark random(9) as deprecated and slated for quick removal.  This is not to
say we intend to remove all fast, non-cryptographic PRNG(s) in the kernel.
It/they just won't be random(9), as it exists today, in either name or
implementation.

Before random(9) is removed, a replacement will be provided and in-tree
consumers will be converted.

Note that despite the name, the random(9) interface does not bear any
resemblance to random(3).  Instead, it is the same crummy 1988 Park-Miller
LCG used in libc rand(3).

b451cd4544 [PowerPC64] Use ld.bfd to build LIB32 and STAND - when using llvm
Summary:
This patch is to support ongoing work for replacing "GCC/BFD" by "CLANG/LLD" on
target PowerPC64 [1], by proposing a way to specify and/or locate a secondary
ld.bfd linker.
This is necessary as LLD currently doesn't support PowerPC 32 bits, so we keep
using BFD for the 32 bit stuff on PowePC64(LIB32 compatibility and
STAND/slof/loader.)

- creates LD_BFD variable pointing to ld.bfd
- use LD_BFD as linker for LIB32/compat
- Default behavior for other platforms aren't changed.

757d4fbaa7 Introduce the concept of busdma tag templates. A template can be allocated
off the stack, initialized to default values, and then filled in with
driver-specific values, all without having to worry about the numerous
other fields in the tag. The resulting template is then passed into
busdma and the normal opaque tag object created.  See the man page for
details on how to initialize a template.

Templates do not support tag filters.  Filters have been broken for many
years, and only existed for an ancient make/model of hardware that had a
quirky DMA engine.  Instead of breaking the ABI/API and changing the
arugment signature of bus_dma_tag_create() to remove the filter arguments,
templates allow us to ignore them, and also significantly reduce the
complexity of creating and managing tags.

284789e871 Update the crypto(4) and crypto(9) manpages.
There are probably bits that are still wrong, but this fixes some
things at least:
- Add named arguments to the functions in crypto(9).
- Add missing algorithms.
- Don't mention arguments that don't exist in crypto_register.
- Add CIOGSESSION2.
- Remove CIOCNFSESSION.
- Clarify some stale language that assumed an fd had only one sesson.
- Note that you have to use CRIOGET and add a note in BUGS lamenting
  that one has to use CRIOGET.
- Various other cleanups.

c0834910ca Better copyright advice
Document the common practices around copyrights with "all rights reserved" in
them as new copyright notices get added.

It's an open question qhether to point people at the fact that since the Berne
convention was ratified, All rights reserved is largely obsolete.
https://en.wikipedia.org/wiki/All_rights_reserved#Obsolescence has the
details. The committer's guide will be revised shortly, and it's likely that's a
better place for this discussion. If not, I'll add a blurb here.

v_usecount. Instead make it available in the same cacheline as the v_op, v_data
and v_type which all get read all the time.

v_type is avoidably 4 bytes while the necessary data will easily fit in 1.
Shrinking it frees up 3 bytes, 2 of which get used here to introduce a new

This makes it possible to retrieve per-connection statistical

them using the stats_voistat_fetch(3) API.

See the net/tcprtt port for an example consumer of this API.

Compared to the existing TCP_INFO system, the main differences
are that this mechanism is easy to extend without breaking ABI,
and provides statistical information instead of raw "snapshots"
of values at a given point in time.  stats(3) is more generic
and can be used in both userland and the kernel.

Using the gpio_pin_* functions to acquire/release/manipulate gpio pins
removes the constraint that both gpio pins must belong to the same gpio
controller/bank, and that the gpioiic instance must be a child of gpiobus.
Removing those constraints allows the driver to be fully compatible with
the modern dts bindings for a gpio bitbanged i2c bus.

For hinted attachment, the two gpio pins still must be on the same gpiobus,
and the device instance must be a child of that bus.  This preserves
compatibility for existing installations that have use gpioiic(4) with hints.

Generally, it's preferred that an application fork/setsid if it doesn't want
to keep its controlling TTY, but it could be that a debugger is trying to
steal it instead -- so it would hook in, drop the controlling TTY, then do
some magic to set things up again. In this case, TIOCNOTTY is quite handy
and still respected by at least OpenBSD, NetBSD, and Linux as far as I can
tell.

I've dropped the note about obsoletion, as I intend to support TIOCNOTTY as

workaround should be removed once the userland can be linked by lld.

003cf08ba9 Revise the page cache size policy.
In r353734 the use of the page caches was limited to systems with a
relatively large amount of RAM per CPU.  This was to mitigate some
issues reported with the system not able to keep up with memory pressure
in cases where it had been able to do so prior to the addition of the
direct free pool cache.  This change re-enables those caches.

The change modifies uma_zone_set_maxcache(), which was introduced
specifically for the page cache zones.  Rather than using it to limit
only the full bucket cache, have it also set uz_count_max to provide an
upper bound on the per-CPU cache size that is consistent with the number
of items requested.  Remove its return value since it has no use.

Enable the page cache zones unconditionally, and limit them to 0.1% of
the domain's pages.  The limit can be overridden by the
vm.pgcache_zone_max tunable as before.

Change the item size parameter passed to uma_zcache_create() to the
correct size, and stop setting UMA_ZONE_MAXBUCKET.  This allows the page
cache buckets to be adaptively sized, like the rest of UMA's caches.
This also causes the initial bucket size to be small, so only systems
which benefit from large caches will get them.

Add bit_ffs_area_at and bit_ffc_area_at functions for searching a bit
string for a sequence of contiguous set or unset bits of at least the
specified size.

The bit_ffc_area function will be used by the Intel ice driver for
implementing resource assignment logic using a bitstring to represent
whether or not a given index has been assigned or is currently free.

The bit_ffs_area, bit_ffc_area_at and bit_ffs_area_at functions are
implemented for completeness.

I'd like to add further test cases for the new functions, but I'm not
really sure how to add them easily. The new functions depend on specific
sequences of bits being set, while the bitstring tests appear to run for
varying bit sizes.

5882cf7159 disable amd(8) by default
As of FreeBSD 10.1 the autofs(5) is available for automounting, and the
amd man page has indicated that the in-tree copy of amd is obsolete.
Disable it by default for now, with the expectation that it will be
removed before FreeBSD 13.0.

506f364029 Add flua to the base system, install to /usr/libexec
FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever
extensions we need for base system operations. We currently support a subset
of lfs and lposix that are used in the rewrite of makesyscall.sh into lua,
added in r354786.

flua is intentionally written such that one can install standard lua and
some set of lua modules from ports and achieve the same effect.

linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added
in. This is similar to what we do in stand/. linit.c has been renamed to
make it clear that this has flua-specific bits.

luaconf has been slightly obfuscated to make extensions more difficult. Part
of the problem is that flua is already hard enough to use as a bootstrap
tool because it's not in PATH- attempting to do extension loading would
require a special bootstrap version of flua with paths changed to protect
the innocent.

src.lua.mk has been added to make it easy for in-tree stuff to find flua,
whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

b141dd5ddf Remove now unused IPv6 macros and update docs.
After r354748-354750 all uses of the IP6_EXTHDR_CHECK() and
IP6_EXTHDR_GET() macros are gone from the kernel.  IP6_EXTHDR_GET0()
was unused.  Remove the macros and update the documentation.

5a2899ac85 Allow per-file lex and yacc options.
In order to allow software with multiple (different) options
for lex and yacc add extra per-file options to the calls.
This is especially useful when one .l file needs -Pprefix.

310399ac72 Fix build race in bsd.files.mk
We need to ensure that installdirs-FOO runs before installfiles-FOO since
otherwise the directory may not exist when we attempt to install the target.
This was randomly causing failures in our Jenkins instance when installing
drti.o in cddl/lib/drti.

dc3c6ad63c Use __ as the separator for the exported vars in bsd.compiler/linker.mk
By using '__' instead of '.' as the separator we can also support systems
that use dash as /bin/sh (it's the default shell on Ubuntu/Debian). Dash
will unset any environment variables that use a non alphanumeric+undedscore
character and therefore submakes will fail to import the COMPILER_*
variables if we use '.' as the separator.

052e12a508 Add the pvscsi driver to the tree.
This driver allows to usage of the paravirt SCSI controller
in VMware products like ESXi.  The pvscsi driver provides a
substantial performance improvement in block devices versus
the emulated mpt and mps SCSI/SAS controllers.

Error handling in this driver has not been extensively tested
yet.

c08973d09c Workaround for Intel SKL002/SKL012S errata.
Disable the use of executable 2M page mappings in EPT-format page
tables on affected CPUs.  For bhyve virtual machines, this effectively
disables all use of superpage mappings on affected CPUs.  The
vm.pmap.allow_2m_x_ept sysctl can be set to override the default and
enable mappings on affected CPUs.

Alternate approaches have been suggested, but at present we do not
believe the complexity is warranted for typical bhyve's use cases.
