userboot has a EXIT_REBOOT code that it uses when the 'reboot' loader
command is executed. Use that and longjmp back to reinit the VM
entirely with a reboot request. This fixes the 'reboot' option in the
loader menu to actually reboot rather than shutdown the VM.
The JMP_* constants are introduced to keep track of why we're doing a
longjmp, though they aren't currently used. We'll notably still do a
complete reload of the interpreter to give the rebooted VM that new
loader smell. It just seemed forward thinking to just keep track of the
different setjmp points.
While we're here, we don't actually need to keep the fd we passed to
fdlopen(3), so let's avoid leaking it.

Explicit Congestion Notification (ECN) is a mechanism that allows
end-to-end notification of network congestion without dropping packets
by explicitly setting the ECN code point (2 bits).
Per RFC 8087, section 3.5, network devices should not be configured to
change the ECN code point in the packets that they forward, except to
set the CE (Congestion Experienced) code point ('11') to signal
incipient congestion.
The current commit adds an -E flag to traceroute6 that crafts a packet
with an ECT(1) code point ('01').
If the packet is received back with a zero ECN code point ('00'), it
outputs that the hop in question erases or "bleaches" the ECN code point
values. Bleaching may occur for various reasons (including normalizing
packets to hide which equipment supports ECN). This policy prevents the
use of ECN by applications.
If the packet is received back with an all-ones ECN code point ('11'),
it outputs that the hop in question is experiencing "congestion".
If the packet is received back with a different ECN code point ('10'),
it outputs that the hop in question changes or "mangles" the ECN code
point values.
If the packet is received with the same ECN code point that was sent
('01'), it outputs that the hop has "passed" the ECN bits appropriately.

Historically, newsyslog compressed rotated log files to save disk space.
This was useful in the early days. However, with modern file systems like
ZFS offering native compression, and with the availability of larger hard
drives, the benefits of additional compression have become less significant.
This is particularly true considering the inconvenience of decompressing
log files when searching for specific patterns.
Additionally, the original implementation of compression methods was not
future-proof. As a result, we have redefined the J, X, Y, Z flags to
signify "treat the file as compressible" rather than "compress the file
with that specific method."
A new command-line option, -c, has been introduced to allow overriding
these settings in a more future-proof way. The available choices are:
* none - do not compress, regardless of flag.
* legacy - historical behavior: J=bzip2, X=xz, Y=zstd, Z=gzip.
* bzip2, xz, zstd, gzip - apply the specified compression method.
Currently, the default is set to 'legacy' to preserve historical behavior.
However, our intention is to change this default to 'none' in FreeBSD 15.0.
Additionally, this update changes the default settings for zstd to use
multithreading and long-range options, better aligning with its intended
use.

release build.
- elf.c is a new file that includes various wrappers around libelf
including routines to read ELF data structures such as program and
section headers and ELF relocations into the "generic" forms
described in <gelf.h>. This file also provides routines for
converting a linker set into an array of addresses (GElf_Addr)
as well as reading architecture-specific mod_* structures and
converting them into "generic" Gmod_* forms where pointers are
replaced with addresses.
- The various architecture-specific reloc handlers now use GElf_*
types for most values (including GElf_Rel and GElf_Rela for
relocation structures) and use routines from <sys/endian.h> to read
and write target values. A new linker set matches reloc handlers
to specific ELF (class, encoding, machine) tuples.
- The bits of kldxref.c that write out linker.hints now use the
encoding (ELFDATA2[LM]SB) of the first file encountered in a
directory to set the endianness of the output file. Input files
with a different architecture in the same directory are skipped with
a warning. In addition, the initial version record for the file
must be deferred until the first record is finished since the
architecture of the output file is not known until then.
- Various places that used 'sizeof(void *)' throughout now use

Currently we just strip the .txz of the dist name (and add a status_
prefix) to get the shell variable name for its status, but this doesn't
give a valid result for dists like base-dbg, kernel-dbg and lib32-dbg,
or even kernel.KERNCONF (or, combining the two, kernel.KERNCONF-dbg). As
a result, four things go wrong for such dists:
1. If there is a dot and/or a dash in the name, writing to the variable
fails and spits an error out on stderr to the log
3. If there is a dot in the name before any dash, the syntax is always
invalid, reading the variable fails, spits an error out on stderr to
the log, the result is the empty string and that is interpreted as
being 0%
2. If there is a dash in the name before any dot, and there is a dist
whose name is the substring up to that first dash, and it has already
had its status written to, reading the variable instead reads that
dist's variable and so the status of that dist is displayed instead
3. If there is a dash in the name before any dot, and either there is
not a dist whose name is the substring up to that first dash or there
is such a dist but it has not already had its status written to,
reading the varaible instead results in the substring after the first
dash, including any additional string expansion syntax that follows
(i.e. ${status_kernel-dbg:--11}, the expression used to read the
variable, is interpreted as reading status_kernel with a default
value of "dbg:--11")
For example, in a default install with base, kernel, kernel-dbg and
lib32, the following sequence of displays happens:
1. base is In Progress, kernel is Pending, kernel-dbg is 0% (what shows
for the garbage input "dbg:--11") and lib32 is Pending
2. base is Passed, kernel is In Progress, kernel-dbg is In Progress
(since kernel has now had its status written to) and lib32 is
Pending
3. base is Passed, kernel is Passed, kernel-dbg is Passed (again, since
that is the status of kernel, despite that kernel-dbg is being
verified at this point) and lib32 is Pending
4. base is Passed, kernel is Passed, kernel-dbg is Passed and lib32 is
In Progress
Fix this with a crude encoding scheme. More special characters can
easily be added if needed in future.
Note that, prior to bsddialog being used (and thus for branches this is
MFC'ed to where dialog is still used), the same problem existed but
displayed slightly differently due to a combination of different default
values and different behaviour for unintended inputs.

libslirp is permissively licensed but has some dependencies which make
it impractical to bring into the base system (glib in particular). I
thus opted to make bhyve dlopen the libslirp.so, which can be installed

The slirp backend takes a "hostfwd" which is identical to QEMU's
hostfwd. When configured, bhyve opens a host socket and listens for
connections, which get forwarded to the guest. For instance,
"hostfwd=tcp::1234-:22" allows one to ssh into the guest by ssh'ing to

Console and tty descriptors are initially opened in parse_action() to

the tty/console under a new descriptor when needed.
If the user attempts to log to a tty that is inactive outside of
syslogd, then syslogd must keep that descriptor open so the tty remains
accessible. For example, logging to `/dev/ttyvb` requires the initial
`/dev/ttyvb` descriptor to stay open so the user can view its buffer at
any time via CTRL+ALT+F12.
As a result, console and tty descriptors must remain open until a

For instance, if a bad choice of mirror was made in the `mirrorselect`

never prompt for a different one. Rebooting is then the only easy way
out of this situation.

instead of pids. Signal delivery is not permitted in capability mode,
so we can use pdkill(2) to terminate child processes.

Add logging sockets directly to the socklist, unless parsing flags. The
peerlist is still needed to temporarily hold socket information until
the configuration flags have been parsed.
It is tempting to remove the entire peerlist, but addsock() can not
determine if syslogd is in secure mode unless the flags have been
parsed.
Also, call pidfile_open() right after flag parsing so we can terminate
if another syslogd instance is already running.

Use kqueue(2) for socket I/O and signal notification. Previously,
select(2) and traditional signal handlers were being used.
This change centralizes all of the async notification delivery into a
single loop so future Capsicum sandboxing will be easier. It also
simplifies the code by removing boiler-plate cruft that comes with the
older interfaces.

cfline() already allocates a filed structure on the heap, so we can
avoid redundant memory allocations by skipping a second calloc() inside
addfile().
addfile() can be removed altogether since a simple STAILQ_INSERT_TAIL()
will add the filed to the global filed list.

Move all configuration-file code outside of the initialization loop and
into its own set of functions. Create a readconfigfile() to open the
config and call parseconfigfile() to parse it.
The init() function no longer returns if there was a failure to open the
configuration file. Initialization will be finished, using the backup
logging rules: *.ERR to /dev/console and *.PANIC to all logged in users.

When populating files, makefs needs to copy their contents into
userspace in order to compute a checksum, so copy_file_range(2) is out
of the question. Though, it could possibly be used when building other
types of filesystems.

Upgrading from FreeBSD 13.2 to 14.0 failed with
install: ///usr/include/c++/v1/__string exists but is not a directory
because __string changed from a file to a directory with an LLVM
upgrade.
Now, remove the existing file when the type conflicts. Note that this
is only an interim fix to facilitate upgrades from 13.2 for 14.0 BETA
testing. This change does not handle the directory -> file case and
further work is needed.

Commit b6e28991bf modified the allocation path for system scope PMCs
so that the event was allocated early for CPU 0. The reason is so that
the PMC's capabilities could be checked, to determine if pmcstat should
allocate the event on every CPU, or just on one CPU in each NUMA domain.
In the current scheme, there is no way to determine this information
without performing the PMC allocation.
This broke the established use-case of log analysis, and so
0aa1507751 was committed to fix the assertion. The result was what
appeared to be functional, but in normal counter measurement pmcstat was
silently allocating two counters for CPU 0.
This cuts the total number of counters that can be allocated from a CPU
in half. Additionally, depending on the particular hardware/event, we
might not be able to allocate the same event twice on a single CPU.
The simplest solution is to release the early-allocated PMC once we have
obtained its capabilities, and reallocate it later on. This restores the
event list logic to behave as it has for many years, and partially
reverts commit b6e28991bf.

Depending on the card's firmware version, it may return different length
responses for MPI2_FUNCTION_IOC_FACTS. But the first part of the
response contains the length of the rest, so query it first to get the
length and then use that to size the buffer for the full response.
Also, correctly zero-initialize MPI2_IOC_FACTS_REQUEST. It only worked
by luck before.

Throughout the bsdinstall script fd 3 is used by f_dprintf (set through
$TERMINAL_STDOUT_PASSTHRU). In several places in the bsdinstalls scripts,
we use fd 3 to juggle stdout when calling out to other tools, which can
cause the installer to fail with a "Bad file descriptor" error when
f_dprintf attempts to use it.
This commit replaces all constructs like this:
exec 3>&1
SOME_VARIABLE=$(some command 2>&1 1>&3)
