Since max allowed size both for keys and values where increased, the

The buffers were reduced in r34146 from default UDP rpcclient values
to 1024/2304 due to the key and value size being 1K.

This version bring many fixes regarding unicode support
It also adds proper support for filename completion (we do not need our custom
patches anymore)
Improves the libreadline compatibility
Note that the same work was done by Yuichiro Naito in
https://reviews.freebsd.org/D21196 the main difference is in this case we have
reimported libedit in contrib to fix a long standing mess in the previous merges
which prevented a proper update workflow. (discussed long ago with pfg@)
The only difference with upstream libedit is we have added a compatibility shim
for the _elf_fn_sh_complete function which we previously added to support quoting
in filename completion and is not needed anymore.
This was added to continue supported old /bin/sh binaries and not break backward
compatibility (as discussed with jilles@)

GEOM is supposed to be topology-agnostic, but the GPT and BSD partition code
has arbitrary restrictions on nesting that are annoying in cases such as
running VMs on raw partitions (since the VM's partitioning scheme is not
visible to the host).
This patch adds sysctls to disable the restrictions except in the case of
BSD label (and similar) partitions with offset 0 (where we need to avoid
recursively recognizing the label).

The symbol version for _mcount was removed 12 years ago in r169525 from
gmon/Symbol.map, to be added to the per-arch Symbol.map. mips was overlooked
in this, so _mcount has no symver. Add it back to where it should have been,
rather than where it would go if it were added today, since we're correcting
a historical mistake.
Additionally, _mcount is getting thrown into .mdebug.abi32 in the llvm80/90
world as it's not getting explicitly thrown into .text, so do this now. This
fixes the libc build that was previously failing due to relocations in
.mdebug.abi32. This is specifically due to the way clang's integrated AS
works and that they emit the .mdebug.abiNN section early in the process. An
LLVM bug has been submitted[0] and an agreement has been made that the
mips backend should switch to .text following .mdebug.abiNN for
compatibility.

The page daemon periodically invokes uma_reclaim() to reclaim cached
items from each zone when the system is under memory pressure. This
is important since the size of these caches is unbounded by default.
However it also results in bursts of high latency when allocating from
heavily used zones as threads miss in the per-CPU caches and must
access the keg in order to allocate new items.
With r340405 we maintain an estimate of each zone's usage of its
(per-NUMA domain) cache of full buckets. Start making use of this
estimate to avoid reclaiming the entire cache when under memory
pressure. In particular, introduce TRIM, DRAIN and DRAIN_CPU
verbs for uma_reclaim() and uma_zone_reclaim(). When trimming, only
items in excess of the estimate are reclaimed. Draining a zone
reclaims all of the cached full buckets (the previous behaviour of
uma_reclaim()), and may further drain the per-CPU caches in extreme
cases.
Now, when under memory pressure, the page daemon will trim zones
rather than draining them. As a result, heavily used zones do not incur
bursts of bucket cache misses following reclamation, but large, unused
caches will be reclaimed as before.

numbers, which are integer-sized, opaque structures initialized
to hold a chosen number of integer and fractional bits.
For a general description of the Q number system, see the "Fixed Point
Representation & Fractional Math" whitepaper[1]; for the actual
API see the qmath(3) man page.
This is one of dependencies for the upcoming stats(3) framework[2]

Although libc syscall wrappers do not get checked in this can aid in
finding the source of generated files when spelunking in the objdir.
Multiple tools use @generated to identify generated files (for example,
in a review Phabricator will by default hide diffs in generated files).
For consistency use the @generated tag in makesyscalls.sh as we've done
for other generated files, even though these wrappers aren't checked in
to the tree.
Use quad.h from libc instead for the time being. This reduces the number of
nearly-identical-quad.h we have in tree to two with only minor changes.
Prototypes for some *sh*di3 have been added to match the copy in libkern.
The differences between the two are likely few enough that they can perhaps
be merged with little additional effort to bring us down to 1.

compatible with existing installations which do not expose keys or

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.
