a21def4d56 pccard: Remove wi(4) driver
Remove wi(4). pccard is going away, and wi only supports PC Card
devices, though it has a minor amount of glue to also support
PCI cards. However, removing the one without removing the other
is hard, so the whole driver is being removed.

9477390796 hid: Import hidraw(4) - driver for access to raw HID device data
This driver provides raw access to HID devices through uhid(4)-compatible
interface and is based on pre-8.x uhid(4) code. Unlike uhid(4) it does
not take devices in to monopoly ownership and allows parallel access
from other drivers.

hidraw supports Linux's hidraw-compatible interface as well.

7b0d3a3ccf include: Use printf(1) instead of shell loops for header symlinks
Using a shell for loop means we have to spawn a separate install(1)
process for each header that is symlinked. This patch uses printf(1) to
generate an argument list that has been prefixed with the correct number
of ../ and then uses a single install(1) invocation.

This reduces the number of execve() calls during make includes from 2442
(with D27622) to 1382. Running `make symlinks` in include/ now spawns 214
processes instead of 1276 without this patch.

cc7edd258c Add collation version support to querylocale(3).
Provide a way to ask for an opaque version string for a locale_t, so
that potential changes in sort order can be detected.  Similar to
ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is
intended to allow databases to detect when text order-based indexes
might need to be rebuilt.

The CLDR version is extracted from CLDR source data by the Makefile
under tools/tools/locale, written into the machine-generated Makefile
under shared/colldef, passed to localedef -V, and then written into
LC_COLLATE file headers.  The initial version is 34.0.
tools/tools/locale was recently updated to pull down 35.0, but the
output hasn't been committed under share/colldef yet, so that will
provide the first observable change when it happens.  Other versioning
schemes are possible in future, because the format is unspecified.

60b426f46c Remove obsolete check for GCC < 3 and support for Intel Compiler
We no longer support old versions of GCC. Remove this check by
assuming it's false. That will make the entire expression false.  Also
remove support for Intel compiler, it's badly bitrotted.  Technically,
this removes support for C89 and K&R from compilers that don't define
_Bool in those compilation environments as well. I'm unaware of any
working compiler today for which that would be relevant (pcc has it
and tcc sadly isn't working for other reasons), though if one
pops up in ports, I'll work to resolve the issue.

9e5787d228 Merge OpenZFS support in to HEAD.
The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.

I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.

Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.

Improvements include:
  project quotas, encrypted datasets,
  allocation classes, vectorized raidz,
  vectorized checksums, various command line
  improvements, zstd compression.

Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many

472ced39ef Implement a close_range(2) syscall
close_range(min, max, flags) allows for a range of descriptors to be
closed. The Python folk have indicated that they would much prefer this
interface to closefrom(2), as the case may be that they/someone have special
fds dup'd to higher in the range and they can't necessarily closefrom(min)
because they don't want to hit the upper range, but relocating them to lower
isn't necessarily feasible.

sys_closefrom has been rewritten to use kern_close_range() using ~0U to
indicate closing to the end of the range. This was chosen rather than
requiring callers of kern_close_range() to hold FILEDESC_SLOCK across the
call to kern_close_range for simplicity.

The flags argument of close_range(2) is currently unused, so any flags set
is currently EINVAL. It was added to the interface in Linux so that future
flags could be added for, e.g., "halt on first error" and things of this
nature.

This patch is based on a syscall of the same design that is expected to be
merged into Linux.

a666325282 Introduce nexthop objects and new routing KPI.
This is the foundational change for the routing subsytem rearchitecture.
 More details and goals are available in https://reviews.freebsd.org/D24141 .

This patch introduces concept of nexthop objects and new nexthop-based
 routing KPI.

Nexthops are objects, containing all necessary information for performing
 the packet output decision. Output interface, mtu, flags, gw address goes
 there. For most of the cases, these objects will serve the same role as
 the struct rtentry is currently serving.
Typically there will be low tens of such objects for the router even with
 multiple BGP full-views, as these objects will be shared between routing
 entries. This allows to store more information in the nexthop.

New KPI:

struct nhop_object *fib4_lookup(uint32_t fibnum, struct in_addr dst,
  uint32_t scopeid, uint32_t flags, uint32_t flowid);
struct nhop_object *fib6_lookup(uint32_t fibnum, const struct in6_addr *dst6,
  uint32_t scopeid, uint32_t flags, uint32_t flowid);

These 2 function are intended to replace all all flavours of
 <in_|in6_>rtalloc[1]<_ign><_fib>, mpath functions  and the previous
 fib[46]-generation functions.

Upon successful lookup, they return nexthop object which is guaranteed to
 exist within current NET_EPOCH. If longer lifetime is desired, one can
 specify NHR_REF as a flag and get a referenced version of the nexthop.
 Reference semantic closely resembles rtentry one, allowing sed-style conversion.

Additionally, another 2 functions are introduced to support uRPF functionality
 inside variety of our firewalls. Their primary goal is to hide the multipath
 implementation details inside the routing subsystem, greatly simplifying
 firewalls implementation:

int fib4_lookup_urpf(uint32_t fibnum, struct in_addr dst, uint32_t scopeid,
  uint32_t flags, const struct ifnet *src_if);
int fib6_lookup_urpf(uint32_t fibnum, const struct in6_addr *dst6, uint32_t scopeid,
  uint32_t flags, const struct ifnet *src_if);

All functions have a separate scopeid argument, paving way to eliminating IPv6 scope
 embedding and allowing to support IPv4 link-locals in the future.

Structure changes:
 * rtentry gets new 'rt_nhop' pointer, slightly growing the overall size.
 * rib_head gets new 'rnh_preadd' callback pointer, slightly growing overall sz.

Old KPI:
During the transition state old and new KPI will coexists. As there are another 4-5
 decent-sized conversion patches, it will probably take a couple of weeks.
To support both KPIs, fields not required by the new KPI (most of rtentry) has to be
 kept, resulting in the temporary size increase.
Once conversion is finished, rtentry will notably shrink.

672e12255d rand(3): Replace implementation with one backed by random(3) algorithm
rand(3)'s standard C API is extremely limiting, but we can do better
than the historical 32-bit state Park-Miller LCG we've shipped since
2001: r73156.

The justification provided at the time for not using random(3) was that
rand_r(3) could not be made to use the same algorithm.  That is still
true.  However, the irrelevance of rand_r(3) is increasingly obvious.
Since that time, POSIX has marked the interface obsolescent.  rand_r(3)
never became part of the standard C library.  If not for API
compatibility reasons, I would just remove rand_r(3) entirely.

So, I do not believe it is a problem for rand_r(3) and rand(3) to
diverge.

The 12 ABI is maintained with compatibility definitions, but this
revision does subtly change the API of rand(3).  The sequences of
pseudorandom numbers produced in programs built against new versions of
libc will differ from programs built against prior versions of libc.

215332ffe7 cdefs: Add __deprecated(message) function attribute macro
The legacy version of GCC4 currently in base does not support the
parameterized form of this function attribute, as recent introduced in
stdlib.h (r355747).

As we have done for other function attributes with similar compatibility
problems, add a version-compatibile definition in sys/cdefs.h.  Note that
Clang defines itself to be GCC 4, so one must check for __clang__ in
addition to __GNUC__ version.  On legacy GCC 4, the macro expands to just
the __deprecated__ attribute; on modern GCC or Clang, the macro expands to
the parameterized variant with the message.

Ignoring legacy or unsupported compilers, the macro is also beneficial in
that it is a bit more ergonomic than the full
__attribute__((__deprecated__())) boilerplate.

c62ff2800b Deprecate sranddev(3) API
It serves no useful purpose and wasn't as popular as its equally meritless
cousin, srandomdev(3).

Setting aside the problems with rand(3) in general, the problem with this
interface is that the seed isn't shared with the caller (other than by
attacking the output of the generator, which is trivial, but not a hallmark of
pleasant API design).  The (arguable) utility of rand(3) or random(3) is as a
semi-fast simulation generator which produces consistent results from a given
seed.  These are mutually at odd.  Furthermore, sometimes people got the
mistaken impression that a high quality random seed meant a weak generator like
rand(3) or random(3) could be used for things like cryptographic key
generation.  This is absolutely not so.

The API was never part of a standard and was not widely used in tree.  Existing
in-tree uses have all been removed.

Possible replacement in out of tree codebases:

	char buf[3];
	time_t t;

	time(t);
	strftime(buf, sizeof(buf), "%S", gmtime(&t));
	srand(atoi(buf));

7dc859a5f3 Add sigsetop extensions commonly found in musl libc and glibc
These functions (sigandset, sigisemptyset, sigorset) are commonly available
in at least musl libc and glibc; sigorset, at least, has proven quite useful
in qemu-bsd-user work for tracking the current process signal mask in a more
self-documenting/aesthetically pleasing manner.

bc053cafca Correctly check for C++17 and higher when declaring timespec_get()
Summary:
In rS338751, the check to declare `timespec_get()` for C++17 and higher
was incorrectly done against a `cplusplus` define, while it should have
been `__cplusplus`.

Fix this by using `__cplusplus`, and also bump `__FreeBSD_version` so it
becomes possible to correctly check for `timespec_get()` in upstream
libc++ headers.

7381dcc9ee libc: remove gets
gets is unsafe and shouldn't be used (for many years now).  Leave it in
the existing symbol version so anything that previously linked aginst it
still runs, but do not allow new software to link against it.

(The compatability/legacy implementation must not be static so that
the symbol and in particular the compat sym gets@FBSD_1.0 make it
into libc.)

6b462d2762 Increase YPMAXRECORD to 16M to be compatible with Linux.
Since YP protocol definition uses the constant to declare
variable-size opaque byte strings, the change should be binary
compatible with existing installations which do not expose keys or
values larger than 1024 bytes.

All uses of local variables with YPMAXRECORD sizes were removed to
avoid insane stack use.  On the other hand, variables with static
lifetime should be fine and only result in increased VA use.

Glibc made same change, increasing the allowed length for keys and
values in YP to 16M, in 2013.
