If not configured, use the historical default of the device page size.
Setting the disk sector size to 512 or 4096 allows a variety of standard

writing frequently to a SPI flash chip like it was a disk drive, but for
data that gets written once (or rarely) and read often, using a standard
filesystem is a nice convenient thing.
@cem removed references to pdwait4(2) (a nonexistent syscall) in
r320058.
This change removes references to pdwait4(2) and `CAP_PDWAIT` in
rights(4) to not mislead the user into thinking that pdwait4(2)/`CAP_PDWAIT` is
actually implemented in the stock FreeBSD kernel.
The goal of this functionality was to simplify monitoring/manipulating
processes started with `pdfork`, et al, and avoid races with waiting on pids.
The syscall was never completed though--just discussed on the capsicum mailing
list back in 2015:
https://lists.cam.ac.uk/pipermail/cl-capsicum-discuss/2015-May/msg00012.html
. That being said, there are members of the project (@rwatson, etc) who
have longterm goals to implement this syscall to better secure pdfork(2)
calls.

Embedded lzma decompression library becomes a module usable by other
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"

for struct ip_mreq remains in place.
The struct ip_mreqn is Linux extension to classic BSD multicast API. It
has extra field allowing to specify the interface index explicitly. In
Linux it used as argument for IP_MULTICAST_IF and IP_ADD_MEMBERSHIP.
FreeBSD kernel also declares this structure and supports it as argument
to IP_MULTICAST_IF since r170613. So, we have structure declared but
not fully supported, this confused third party application configure
scripts.
Code handling IP_ADD_MEMBERSHIP was mixed together with code for
IP_ADD_SOURCE_MEMBERSHIP. Bringing legacy and new structure support
into the mess would made the "argument switcharoo" intolerable, so

Add or fix options to control static and dynamic configuration. Keep
the default of scteken, but default to statically configuring all available
emulators (now 3 instead of 1).
The dumb emulator is almost usable. libedit and libreadline handle
dumb terminals perfectly for at least shell history. less(1) works
as well as possible except on exit. But curses programs make messes.
The dumb emulator has strange color support, with 2 dumb colors for
normal output but fancy colorization for the cursor, mouse pointer and
(with a non-dumb initial emulator) for low-level console output.
Using the sc emulator instead of the default of scteken fixes at least
the following bugs:
- NUL is a printing character in cons25 but not in teken
- teken doesn't support fixed colors for "reverse" video.
- The best versions of sc are about 10 times faster than scteken (for
printing to the frame buffer). This version is only about 5 times
faster.
Fix configuration features:
- make SC_DFLT_TERM (for setting the initial emulator) a normal option.
Add configuration features:
- negative options SC_NO_TERM_* for omitting emulators in the static config.
Modules for emulators might work, but I don't know of any
- vidcontrol -e shows the available emulators
- vidcontrol -E <emulator> sets the active emulator.
The move to /usr/include/private prefixed paths seems to require a bit more
effort in order to compile programs.
Install the headers to /usr/include/private/g{mock,test}/... and automatically
include /usr/include/private in GTESTS_CXXFLAGS to make compilation seamless. I
will work on the more global problem later with @bdrewery.
A previous iteration referenced/used googletest.test.flags.mk, not
googletest.test.inc.mk. The latter name is what I settled on as this
Makefile snippet can include more logic than flags.
Long story short, some of the tests were failing because they expected either
dynamic_cast or RTTI to be functional and it wasn't.
Move all common CXXFLAGS out to googletest.test.inc.mk and reference it from
googletest.test.mk and .../googletest/Makefile.inc
googletest.test.mk is a rudimentary wrapper around the plain test interface
(for now), which only supports C++ programs, specified by the `GTESTS`
variable.
In the future, kyua will support gtests in a more native manner.
These libraries don't compile on non-C++-11 capable compilers, e.g., g++ 4.2.1
and its corresponding implementation of the c++ library, i.e., libstdc++.
Blacklist compilation on all non-C++-11 capable compilers and give others the
option of opting out of building/installing gmock/gtest via MK_GOOGLETEST.
This option is controlled by MK_CXX and MK_TESTS, as ATF compilation is.
Building binaries as PIE allows the executable itself to be loaded at a
random address when ASLR is enabled (not just its shared libraries).
With this change PIE objects have a .pieo extension and INTERNALLIB
libraries libXXX_pie.a.
MK_PIE is disabled for some kerberos5 tools, Clang, and Subversion, as
they explicitly reference .a libraries in their Makefiles. These can
be addressed on an individual basis later. MK_PIE is also disabled for
rtld-elf because it is already position-independent using bespoke
Makefile rules.
Currently only dynamically linked binaries will be built as PIE.

The KPI have been reviewed and cleansed of features that were planned
back 20 years ago and never implemented. The pfil(9) internals have
been made opaque to protocols with only returned types and function
declarations exposed. The KPI is made more strict, but at the same time
more extensible, as kernel uses same command structures that userland
ioctl uses.
In nutshell [KA]PI is about declaring filtering points, declaring
filters and linking and unlinking them together.
New [KA]PI makes it possible to reconfigure pfil(9) configuration:
change order of hooks, rehook filter from one filtering point to a
different one, disconnect a hook on output leaving it on input only,
prepend/append a filter to existing list of filters.
Now it possible for a single packet filter to provide multiple rulesets
that may be linked to different points. Think of per-interface ACLs in
Cisco or Juniper. None of existing packet filters yet support that,
however limited usage is already possible, e.g. default ruleset can
be moved to single interface, as soon as interface would pride their
filtering points.
Another future feature is possiblity to create pfil heads, that provide
not an mbuf pointer but just a memory pointer with length. That would
allow filtering at very early stages of a packet lifecycle, e.g. when
packet has just been received by a NIC and no mbuf was yet allocated.

In 12.0 LLD is the system linker on amd64, arm64, and armv7. i386 was
not switched initially as there were additional ports failures not found
on amd64. Those have largely been addressed now, although there are a
small number of issues that are still being worked on. In some of these

Some rc scripts in ports (e.g. uwsgi, apache, openvpn) allow for
'application profiles' that usually require the rc script to be invoked
again for each active profile. Because there's no consistent way to
determine the path because it differs between manual/service(8) invocations
and /etc/rc invocations, this leads to patterns like these:
- www/uwsgi hardcodes the script path
- security/openvpn guesses either $_file or $0 based on $0 = /etc/rc
Instead of forcing rc scripts to guess, provide an rc_service variable to
the scripts that gets set appropriately both for direct execution or when a
script is being executed via run_rc_script (e.g. /etc/rc).
This is our analog of an OpenRC variable with the same name, different case

pfsync code is called for every new state, state update and state
deletion in pf. While pf itself can operate on multiple states at the
same time (on different cores, assuming the states hash to a different
hashrow), pfsync only had a single lock.
This greatly reduced throughput on multicore systems.
Address this by splitting the pfsync queues into buckets, based on the
state id. This ensures that updates for a given connection always end up
in the same bucket, which allows pfsync to still collapse multiple
updates into one, while allowing multiple cores to proceed at the same
time.
The number of buckets is tunable, but defaults to 2 x number of cpus.

We generally document shutdown(8) instead of reboot(8) as it's better for
interactive use.
In modern FreeBSD is matters a lot less, it's mostly just convention. One
minor thing is that shutdown(8) produces a global message, while reboot(8)
does not. It is believed that historically, some versions of reboot did not
do appropriate safe shutdown checks and just rebooted.
It's also just consistency: for example the handbook[1] documents shutdown.
There is actually another important difference between reboot and shutdown
-r now: reboot does not run /etc/rc.shutdown. This is because reboot has
its own shutdown procedure and does not signal init like init 6 and
shutdown -r now do (except in the case of rerooting via reboot -r).
A few years ago jilles@ proposed changing reboot's default to signalling
init (preserving reboot -q which just invokes the reboot system call), but
this was not accepted. Perhaps this can be tried again for 13.0.

The linker's -z now flag sets the DF_BIND_NOW flag, which signals to the
runtime loader that all relocation processing should be performed at
process startup rather than on demand. In combination with lld's
default of enabling relro this causes the GOT to be made read-only when
the process starts, preventing straightforward GOT overwrite attacks.
Shawn Webb discovered a failure on HardenedBSD with BIND_NOW and ifunc
use, which resulted in my rtld fix in r340137. Add a BIND_NOW knob as
it is trivial to do so and is a useful ELF hardening feature. This
change is equivalent to HardenedBSD's but not identical as there are
other diffs/conflicts nearby.
Note that our ELF Tool Chain readelf does not currently decode the
DF_BIND_NOW flag - see PR232983.

It uses sequence numbers of PPtPGRE packets.
A set of new sysctl(8) added to control this ability or disable it:
net.graph.pptpgre.reorder_max (1) defines maximum length of node's
private reorder queue used to keep data waiting for late packets.
Zero value disables reordering. Default value 1 allows the node to restore
the order for two packets swapped in transit. Greater values allow the node
to deliver packets being late after more packets in sequence
at cost of increased kernel memory usage.
net.graph.pptpgre.reorder_timeout (1) defines time value in miliseconds
used to wait for late packets. It may be useful to increase this
if reordering spot is distant.

You should not be using DES. You should not have been using DES for the
past 30 years.
The ed DES-CBC scheme lacked several desirable properties of a sealed
document system, even ignoring DES itself. In particular, it did not
provide the "integrity" cryptographic property (detection of tampering), and
it treated ASCII passwords as 64-bit keys (instead of using a KDF like
scrypt or PBKDF2).
Some general approaches ed(1) users might consider to replace the removed
DES mode:
1. Full disk encryption with something like AES-XTS. This is easy to
conceptualize, design, and implement, and it provides confidentiality for
data at rest. Like CBC, it lacks tampering protection. Examples include
GELI, LUKS, FileVault2.
2. Encrypted overlay ("stackable") filesystems (EncFS, PEFS?, CryptoFS,
others).
3. Native encryption at the filesystem layer. Ext4/F2FS, ZFS, APFS, and
NTFS all have some flavor of this.
4. Storing your files unencrypted. It's not like DES was doing you much
good.
If you have DES-CBC scrambled files produced by ed(1) prior to this change,
you may decrypt them with:
openssl des-cbc -d -iv 0 -K <key in hex> -in <inputfile> -out <plaintext>

Remove malloc_domain(9) and most other _domain KPIs added in r327900.
The new functions allow the caller to specify a general NUMA domain
selection policy, rather than specifically requesting an allocation from
a specific domain. The latter policy tends to interact poorly with
M_WAITOK, resulting in situations where a caller is blocked indefinitely
because the specified domain is depleted. Most existing consumers of
the _domain KPIs are converted to instead use a DOMAINSET_PREF() policy,
in which we fall back to other domains to satisfy the allocation
request.
This change also defines a set of DOMAINSET_FIXED() policies, which
only permit allocations from the specified domain.

In the last decade(s) we have seen both short term or long term projects
committed to the tree which were considered or even marked "experimental".
While out-of-tree development has become easier than it used to be in
CVS times, there still is a need to have the code shipping with HEAD but
not enabled by default.
While people may think about VIMAGE as one of the recent larger, long term
projects, early protocol implementations (before they are standardised)
are others. (Free)BSD historically was one of the operating systems
which would have running code at early stages and help develop and
influence standardisation and the industry.
Give developers an opportunity to be more pro-active for early adoption
or running large scale code changes stumbling over each others but not
the user's feet. I have not added the option to NOTES in order to avoid
breaking supported option builds, which require constant compile testing.

When building CheriBSD we have to set XLD/XCC/XCFLAGS on the command line.
This triggers the $XCC != $CC case in bsd.compiler.mk (and the same for LD
in bsd.linker.mk) which causes it to call ${XCC} --version and
${XLD} --version (plus various awk+sed+echo calls) in every subdirectory.
For incremental builds and stages that only walk the source tree this is
often the majority of the time spent in that directory.
By only computing the value of the X_COMPILER_*/X_LINKER_* variables if
_WANT_TOOLCHAIN_CROSS_VARS is set we can reduce the number of cc/ld calls
to once per build stage instead of once per recursive make.
With this change (and no changes to the sources) the `make includes` stage
now takes 28 seconds at -j1 instead of 86 seconds.
