Upstream commit message:
Support running FreeBSD buildworld on Arm-based macOS hosts
Arm-based Macs are like FreeBSD and provide a full 64-bit stat from the
start, so have no stat64 variants. Thus, define stat64 and fstat64 as
aliases for the normal versions.

ipf_proxy_check() returns -1 for an error and 0 or 1 for success.
ipf_proxy_check()'s callers check for error and if the return code
is 0, they change it to 1 prior to returning to their callers. Simply
by returning -1 or 1 we reduce complexity and cycles burned changing
0 to 1.

The global list has a marker with an invariant that free vnodes are
placed somewhere past that. A caller which performs filtering (like ZFS)
can move said marker all the way to the end, across free vnodes which
don't match. Then a caller which does not perform filtering will fail to
find them. This makes vn_alloc_hard sleep for 1 second instead of
reclaiming, resulting in significant stalls.
Fix the problem by requiring an explicit marker by callers which do
filtering.
As a temporary measure extend vnlru_free to restart if it fails to
reclaim anything.
Big thanks go to the reporter for testing several iterations of the
patch.

LARGE_NAT is a C macro that increases

These values can be altered at runtime using the ipf -T command however
some adminstrators of large firewalls rebuild the kernel to enable
LARGE_NAT at boot. This revision adds the tunable net.inet.ipf.large_nat

When scrubbing, (non-sequential) resilvering, or correcting a checksum
error using RAIDZ parity, ZFS should heal any incorrect RAIDZ parity by
overwriting it. For example, if P disks are silently corrupted (P being
the number of failures tolerated; e.g. RAIDZ2 has P=2), `zpool scrub`
should detect and heal all the bad state on these disks, including
parity. This way if there is a subsequent failure we are fully
protected.
With RAIDZ2 or RAIDZ3, a block can have silent damage to a parity
sector, and also damage (silent or known) to a data sector. In this
case the parity should be healed but it is not.

Direct commit from upstream openzfs. Full commit message below:
Set file mode during zfs_write
3d40b65 refactored zfs_vnops.c, which shared much code verbatim between
Linux and BSD. After a successful write, the suid/sgid bits are reset,
and the mode to be written is stored in newmode. On Linux, this was
propagated to both the in-memory inode and znode, which is then updated
with sa_update.
3d40b65 accidentally removed the initialization of newmode, which
happened to occur on the same line as the inode update (which has been
moved out of the function).
The uninitialized newmode can be saved to disk, leading to a crash on
stat() of that file, in addition to a merely incorrect file mode.

This change introduces loadable fib lookup modules based on
DPDK rte_lpm lib targeted for high-speed lookups in large-scale tables.
It is based on the lookup framework described in D27401.
IPv4 module is called dpdk_lpm4. It wraps around rte_lpm [1] library.
This library implements variation of DIR24-8 [2] lookup algorithm.
Module provide lockless route lookups and in-place incremental updates,
allowing for good RIB performance.
IPv6 module is called dpdk_lpm6. It wraps around rte_lpm6 [3] library.
Implementation can be seen as multi-bit trie where the stride or number of bits
inspected on each level varies from level to level.
It can vary from 1 to 14 memory accesses, with 5 being the average value
for the lengths that are most commonly used in IPv6.
Module provide lockless route lookups for global unicast addresses
and in-place incremental updates, allowing for good RIB performance.
Implementation details:
* wrapper code lives in `sys/contrib/dpdk_rte_lpm/dpdk_lpm[6].c`.
* rte_lpm[6] implementation contains both RIB and FIB code.
. RIB ("rule_") code, backed by array of hash tables part has been commented out,
as base radix already provides all the necessary primitives.
* link-local lookups are currently implemented as base radix lookup.
This part should be converted to something like read-only radix trie.
Usage detail:
Compile kernel with option FIB_ALGO and load dpdk_lpm4/dpdk_lpm6
module at any time. They will be picked up automatically when
amount of routes raises to several thousand.

be emitted and the value of the address may be replaced with zero.
Howerver, buggy versions don't emit the warning or replace the value

Replace MAXPHYS by runtime variable maxphys. It is initialized from
MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys.
Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer
cache buffers exactly to atop(maxbcachebuf) (currently it is sized to
atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1.
The +1 for pbufs allow several pbuf consumers, among them vmapbuf(),
to use unaligned buffers still sized to maxphys, esp. when such
buffers come from userspace (*). Overall, we save significant amount
of otherwise wasted memory in b_pages[] for buffer cache buffers,
while bumping MAXPHYS to desired high value.
Eliminate all direct uses of the MAXPHYS constant in kernel and driver
sources, except a place which initialize maxphys. Some random (and
arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted
straight. Some drivers, which use MAXPHYS to size embeded structures,
get private MAXPHYS-like constant; their convertion is out of scope
for this work.

Make the inlines static to avoid kernel build failure with Clang 11 on i386.
(The issue was not observed with Clang 10, currently in tree; reproduction
depends on compiler inlining choices.)
The compiler may choose not to inline 'bare' C inlines, and in that case
expects a symbol of the same name will be available. It does not
automatically define that symbol at use, because of traditional C linking
semantics. (In contrast, C++ does define it, and then deduplicates redundant
definitions at link). As we do not instantiate the C99 inline ('extern

Add prng(9) as a replacement for random(9) in the kernel.
There are two major differences from random(9) and random(3):
- General prng(9) APIs (prng32(9), etc) do not guarantee an
implementation or particular sequence; they should not be used for
repeatable simulations.
- However, specific named API families are also exposed (for now: PCG),
and those are expected to be repeatable (when so-guaranteed by the named
algorithm).
Some minor differences from random(3) and earlier random(9):
- PRNG state for the general prng(9) APIs is per-CPU; this eliminates
contention on PRNG state in SMP workloads. Each PCPU generator in an
SMP system produces a unique sequence.
- Better statistical properties than the Park-Miller ("minstd") PRNG
(longer period, uniform distribution in all bits, passes
BigCrush/PractRand analysis).
- Faster than Park-Miller ("minstd") PRNG -- no division is required to
step PCG-family PRNGs.
For now, random(9) becomes a thin shim around prng32(). Eventually I
would like to mechanically switch consumers over to the explicit API.

Although I added the reset type field to ath_hal_reset() years ago,
I never finished adding it both throughout the HALs and in if_ath.c.
This will eventually deprecate the ath_hal force_full_reset option
because it can be requested at the driver layer.
So:
* Teach ar5416ChipReset() and ar9300_chip_reset() about the HAL type
* Use it in ar5416Reset() and ar9300_reset() when doing a full chip reset
* Extend ath_reset() to include the HAL_RESET_TYPE parameter added in the above functions
* Use HAL_RESET_NORMAL in most calls to ath_reset()
* .. but use HAL_RESET_BBPANIC for the BB panics, and HAL_RESET_FORCE_COLD during fatal, beacon miss and other hardware related hangs.
This should be a glorified no-op outside of actual hardware issues.
I've tested things with ath_hal force_full_reset set to 1 for years now,
so I know that feature and a full reset works (albeit much slower than
a warm reset!) and it does unwedge hardware.
The eventual aim is to use this for all the places where the driver
detects a potential hang as well as if long calibration - ie, noise floor
calibration - fails to complete. That's one of the big hardware related
things that causes station mode operation to hang without easy recovery.

Yes, people shouldn't use bitfields in C for structure parsing.
If someone ever wants a cleanup task then it'd be great to remove them
from this vendor code and other places in the ar9285/ar9287 HALs.
Alas, here we are.
AH_BYTE_ORDER wasn't defined and neither were the two values it could be.
So when compiling ath_ee_print_9300 it'd default to the big endian struct
layout and get a WHOLE lot of stuff wrong.
So:
* move AH_BYTE_ORDER into ath_hal/ah.h where it can be used by everyone.
* ensure that AH_BYTE_ORDER is actually defined before using it!
This should work on both big and little endian platforms.
Ok, yeah, the commit title is a bit misleading.
This has to do with CDD (cyclic delay diversity) - how this and later
wifi hardware transmits lower rates over more antennas. Eg, if you're
transmitting legacy 11abg rates on 2 or 3 antennas, you COULD just
send them all at the same time or you could delay each by tens/hundreds
of nanoseconds to try and get some better diversity characteristics.
However, this has a fun side effect - the antenna pattern is no longer
a bunch of interacting dipoles, but are a bunch of interacting dipoles
plus a bunch of changing phases. And it's frequency dependent - 50-200nS
is not exactly the same fraction of a wavelength across all of 2GHz or 5GHz!
Thus the power spectral density and maximum directional gain that you're
effectively getting is not .. well, as flat as it once was.
For more information, look up FCC/OET 13TR1003 in the FCC technical report
database. It has pretty graphics and everything.
Anyway, the problem lies thusly - the CDD code just subtracts another 3dB
or 5dB for the lower rates based on transmit antenna configuration.
However, it's not done based on operating configuration and it doesn't
take into account how far from any regulatory limits the hardware is at.
It also doesn't let us do things like transmit legacy rates and frames
on a single antenna without losing up to 5dB when we absolutely don't
need to in that case (there's no CDD used when one antenna is used!)
This shows up as the hardware behaving even worse for longer distance links
at 20MHz because, well, those are the exact rates losing a bunch more
transmit power.
* For lower power NICs (ie the majority of what is out there!) it's highly
unlikely we're going to hit anywhere near the PSD limits.
* It's doing it based on the existing limits from the CTL table (conformance
testing limits) - this isn't the regulatory max! It's what the NIC is
allowed to put out in each frequency and rate configuration! So things like
band edges, power amplifier behaviour and maximum current draw apply here.
Blindly subtracting 3 to 5dB from /this/ value is /very/ conservative..
* /and/ ath9k just plainly doesn't do any of this at all.
So, for now disable it and get the TX power back, thus matching what ath9k
in Linux is doing. If/once I get some more cycles I'll look at making it
a bit more adaptive and really only kick in if we're a few dB away from
hard regulatory limits.
Tested:
* AR9344 (2GHz + SoC, 2x2 configuration) - AP and STA modes
* QCA9580 (5GHz 2x2 and 3x3 configurations) - AP and STA modes

When epoch(9) was introduced to network stack, it was basically
dropped in place of existing locking, which was mutexes and
rwlocks. For the sake of performance mutex covered areas were
as small as possible, so became epoch covered areas.
However, epoch doesn't introduce any contention, it just delays
memory reclaim. So, there is no point to minimise epoch covered
areas in sense of performance. Meanwhile entering/exiting epoch
also has non-zero CPU usage, so doing this less often is a win.
Not the least is also code maintainability. In the new paradigm
we can assume that at any stage of processing a packet, we are
inside network epoch. This makes coding both input and output
path way easier.
On output path we already enter epoch quite early - in the
ip_output(), in the ip6_output().
This patch does the same for the input path. All ISR processing,
network related callouts, other ways of packet injection to the
network stack shall be performed in net_epoch. Any leaf function
that walks network configuration now asserts epoch.
Tricky part is configuration code paths - ioctls, sysctls. They
also call into leaf functions, so some need to be changed.
This patch would introduce more epoch recursions (see EPOCH_TRACE)
than we had before. They will be cleaned up separately, as several
of them aren't trivial. Note, that unlike a lock recursion the
epoch recursion is safe and just wastes a bit of resources.

Clang sees this construct and warns that adding an int to a string like this
does not concatenate the two. Fortunately, this is not what octeon-sdk
actually intended to do, so we take the path towards remediation that clang
offers: use array indexing instead.
There are several mechanisms by which a vm_page reference is held,
preventing the page from being freed back to the page allocator. In
particular, holding the page's object lock is sufficient to prevent the
page from being freed; holding the busy lock or a wiring is sufficent as
well. These references are protected by the page lock, which must
therefore be acquired for many per-page operations. This results in
false sharing since the page locks are external to the vm_page
structures themselves and each lock protects multiple structures.
Transition to using an atomically updated per-page reference counter.
The object's reference is counted using a flag bit in the counter. A
second flag bit is used to atomically block new references via
pmap_extract_and_hold() while removing managed mappings of a page.
Thus, the reference count of a page is guaranteed not to increase if the
page is unbusied, unmapped, and the object's write lock is held. As
a consequence of this, the page lock no longer protects a page's
identity; operations which move pages between objects are now
synchronized solely by the objects' locks.
The vm_page_wire() and vm_page_unwire() KPIs are changed. The former
requires that either the object lock or the busy lock is held. The
latter no longer has a return value and may free the page if it releases
the last reference to that page. vm_page_unwire_noq() behaves the same
as before; the caller is responsible for checking its return value and
freeing or enqueuing the page as appropriate. vm_page_wire_mapped() is
introduced for use in pmap_extract_and_hold(). It fails if the page is
concurrently being unmapped, typically triggering a fallback to the
fault handler. vm_page_wire() no longer requires the page lock and
vm_page_unwire() now internally acquires the page lock when releasing
the last wiring of a page (since the page lock still protects a page's
queue state). In particular, synchronization details are no longer
leaked into the caller.
The change excises the page lock from several frequently executed code
paths. In particular, vm_object_terminate() no longer bounces between
page locks as it releases an object's pages, and direct I/O and
sendfile(SF_NOCACHE) completions no longer require the page lock. In
these latter cases we now get linear scalability in the common scenario
where different threads are operating on different files.
__FreeBSD_version is bumped. The DRM ports have been updated to
accomodate the KPI changes.

broken ipfilter rule matches (upstream bug #554). The upstream patch
was incomplete, it resolved all but one rule compare issue. The issue
fixed here is when "{to, reply-to, dup-to} interface" are used in
conjuncion with "on interface". The match was only made if the on keyword
was specified in the same order in each case referencing the same rule.
This commit fixes this.
The reason for this is that interface name strings and comment keyword
comments are stored in a a variable length field starting at fr_names
in the frentry struct. These strings are placed into this variable length
in the order they are encountered by ipf_y.y and indexed through index
pointers in fr_ifnames, fr_comment or one of the frdest struct fd_name
fields. (Three frdest structs are within frentry.) Order matters and
this patch takes this into account.
While in here it was discovered that though ipfilter is designed to
support multiple interface specifiations per rule (up to four), this
undocumented (the man page makes no mention of it) feature does not work.
A todo is to fix the multiple interfaces feature at a later date. To
understand the design decision as to why only four were intended, it is
suspected that the decision was made because Sun workstations and PCs
rarely if ever exceeded four NICs at the time, this is not true in 2019.

The hold_count and wire_count fields of struct vm_page are separate
reference counters with similar semantics. The remaining essential
differences are that holds are not counted as a reference with respect
to LRU, and holds have an implicit free-on-last unhold semantic whereas
vm_page_unwire() callers must explicitly determine whether to free the
page once the last reference to the page is released.
This change removes the KPIs which directly manipulate hold_count.
Functions such as vm_fault_quick_hold_pages() now return wired pages
instead. Since r328977 the overhead of maintaining LRU for wired pages
is lower, and in many cases vm_fault_quick_hold_pages() callers would
swap holds for wirings on the returned pages anyway, so with this change
we remove a number of page lock acquisitions.

One of the fun issues with scanning has been how the existing
ANI values were programmed into the hardware when channels were
changed. If you're on a really crappy channel and ANI has made
you deaf then when you scan you continue to be deaf on all channels.
This code passes in a flag to startpcureceive which in AR5416 and later
is also used to enable ANI. This allows it to know if it's a normal
operation or a scan operation.
This fixes my situation at home where a temporary spot of a device
going deaf due to interference starts scanning and .. can't hear
anything until I restart.
Now, this isn't the full fix - ideally:
(a) all the ANI config and per-channel information would be migrated
to the shared HAL stuff and enabled for all of the NICs;
(b) when a station reassociates and some other error conditions
(like missed beacons, NF calibration failures, etc) a knob
to reset ANI parameters would likely help recovery.

consumers, in addition to geom_uzip.
Most important code changes are
- removal of XZ_DEC_SINGLE define, we need the code to work
with XZ_DEC_DYNALLOC;
- xz_crc32_init() call is removed from geom_uzip, xz module handles
initialization on its own.
xz is no longer embedded into geom_uzip, instead the depend line for
the module is provided, and corresponding kernel option is added to
each MIPS kernel config file using geom_uzip.
The commit also carries unrelated cleanup by removing excess "device geom_uzip"
in places which were missed in r344479.

In r343986 we introduced a double free. The structure was already
freed fixed in the r302966. This problem was introduced
because the GitHub version was out of sync with the FreeBSD one.
