Previously, it used atoi(3) to parse the unit parameter, which would silently
yield a unit of 0 in the presence of an invalid unit number. As most users of
mpsutil(8) are likely to have at least a unit 0, this is could have confusing
results.
This behaviour was particularly unintuitive if one incorrectly passed an
adapter device name, or a device path, instead of a unit number. In addition
to using strtoumax(3) instead of atoi(3) to parse unit numbers, support
stripping a device name (e.g. mps1) or path (e.g. /dev/mps2) to just its unit
number.

Currently newsyslog supports <include> directive that is used
in our default /etc/newsyslog.conf in the following form:
<include> /usr/local/etc/newsyslog.conf.d/*
While this is suitable for ports installing their own rules
for logs rotation, this also makes newsyslog break entire
processing of all files if it encounters single line it cannot parse.
This includes lines referring to nonexistent username/group for log
ownership, so newsyslog stops calling errx() function in the parser.
With this fix, newsyslog uses warnx() instead of errx() in such cases
to print a warning, recover gracefully and continue with execution.
Among other cases, this unbreaks initial creation of log files
having flag "C" at boot time (newsyslog -CN). This is most important
for systems having RAM-based /var file system like nanobsd(8)-based
that rely on newsyslog to bring system log files into existence.

As of r359457 we removed the GDB_LIBEXEC option, always installing in-tree
gdb into /usr/libexec/. Thus, there is now no need for crashinfo to include
/usr/bin/gdb in the list of pathnames to check when looking for gdb.
Without this patch, if a SIGHUP is handled while the process is executing
get_exportlist(), that SIGHUP is essentially ignored because the got_sighup
variable is reset to 0 after get_exportlist().
This results in the exports file(s) not being reloaded until another SIGHUP
signal is sent to mountd.
This patch fixes this by resetting got_sighup to zero before the
get_exportlist() call while SIGHUP is blocked.
It also defines a delay time of 250msec before doing another exports reload
if there are RPC request(s) to process. This prevents repeated exports reloads
from delaying handling of RPC requests significantly.

When WITHOUT_SENDMAIL is set, we end up with two different mailer.conf that

This patch simplifies the whole situation; remove the ^/etc/Makefile version

scenarios covered in mailwrapper are:
- sendmail(8) is installed, dma(8) may or may not be installed
- neither sendmail(8) nor dma(8) is installed

Save and restore (also known as suspend and resume) permits a snapshot
to be taken of a guest's state that can later be resumed. In the
current implementation, bhyve(8) creates a UNIX domain socket that is
used by bhyvectl(8) to send a request to save a snapshot (and
optionally exit after the snapshot has been taken). A snapshot
currently consists of two files: the first holds a copy of guest RAM,
and the second file holds other guest state such as vCPU register
values and device model state.
To resume a guest, bhyve(8) must be started with a matching pair of
command line arguments to instantiate the same set of device models as
well as a pointer to the saved snapshot.
While the current implementation is useful for several uses cases, it
has a few limitations. The file format for saving the guest state is
tied to the ABI of internal bhyve structures and is not
self-describing (in that it does not communicate the set of device
models present in the system). In addition, the state saved for some
device models closely matches the internal data structures which might
prove a challenge for compatibility of snapshot files across a range
of bhyve versions. The file format also does not currently support
versioning of individual chunks of state. As a result, the current
file format is not a fixed binary format and future revisions to save
and restore will break binary compatiblity of snapshot files. The
goal is to move to a more flexible format that adds versioning,
etc. and at that point to commit to providing a reasonable level of
compatibility. As a result, the current implementation is not enabled
by default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes option
for userland builds, and the kernel option BHYVE_SHAPSHOT.

The bhyve NVMe emulation has a race in the logic which generates command
completion interrupts. On FreeBSD guests, this manifests as kernel log
messages similar to:
nvme0: Missing interrupt
The NVMe emulation code sets a per-submission queue "busy" flag while
processing the submission queue, and only generates an interrupt when
the submission queue is not busy.
Aside from being counter to the NVMe design (i.e. interrupt properties
are tied to the completion queue) and adding complexity (e.g. exceptions
to not generating an interrupt when "busy"), it causes a race condition
under the following conditions:
- guest OS has no outstanding interrupts
- guest OS submits a single NVMe IO command
- bhyve emulation processes the SQ and sets the "busy" flag
- bhyve emulation submits the asynchronous IO to the backing storage
- IO request to the backing storage completes before the SQ processing
loop exits and doesn't generate an interrupt because the SQ is "busy"
- bhyve emulation finishes processing the SQ and clears the "busy" flag
Fix is to remove the "busy" flag and generate an interrupt when the CQ
head and tail pointers do not match.

Property-based filters allow substring and regular expressions
(see re_format(7)) matching against various message attributes.
Filter specification starts with '#:' or ':' followed by three
comma-separated fields property, operator, "value". Value must be
double-quoted. A double quote and backslash must be escaped by a
blackslash.
Following properties are supported as test value:
o msg - body of the message received;
o programname - program name sent the message;
o hostname - hostname of message's originator;
o source - an alias for hostname.
Supported operators:
o contains - true if filter value is found as a substring of property;
o isequal - true if filter value is equal to property;
o startswith - true if property starts with filter value;
o regex - true if property matches basic regular expression defined
in filter value;
o ereregex - true if property matches extended regular expression
defined in filter value;
Operator may be prefixed by '!' to invert compare logic or by
'icase_' to make comparison function case insensitive.

This happens when compressing a previously uncompressed already-rotated

Reverts r358561.
With powerd_flags="-N", this makes powerd(8) exclude "nice" time when
computing the CPU utilization. This makes it possible to prevent
CPU-intensive "background" processes from spinning up the CPU.
Note that only *userland* CPU usage belonging to "nice" processes is
excluded; we do not track whether time spent in the kernel is on behalf
of nice or non-nice processes, so kernel-intensive nice processes can
still result in the CPU being sped up.

Document better this file, updating the URL to the IANA registry and closely

For system ports (0 to 1023) we now try to follow the registry closely, noting

As a side effect: drop references to unofficial Kerberos IV which was EOL'ed

very old FreeBSD machines that can't be replaced easily, the use of it is
considered a security risk. Also drop the unofficial netatalk, which we
supported long ago in the kernel but was dropped long ago.
Leave for now smtps, even though it conflicts with IANA's submissions.
The change should have very little visibility, if any, but should be a
step closer to the current IANA database.

Give up the battle to keep extra files in $MACHINE/compile to keep the file in
the tree. Instead, create CDIR (usually ../compile) if it doesn't exist when
we're using a default build location (eg, not using -d). If it does, we do
nothing. This only affects people that do old-school builds, but it's bit me a
dozen times since last summer so time to fix the bug.
This change reflects the ability to change machine_arch in a config file. This
is useful for including one config in another and changing the machine_arch
in the second one.
Currently, you can have multiple machine directives if they are otherwise
identical. Relax this so that only the machinename part is the same. This allows
one to change the machine arch in a different config file you've included easily.
Currently, the size of the swap device is unconditionally reported using
blocks, even if -h has been used.
- While here, switch to CONVERT_BLOCKS() instead of CONVERT() which will
avoid overflowing size counters (in human readable form see: r196244)
- Update the column headers to reflect that a size is being reported instead
of the block size units being used

This patch adds a new netbe_peek_recvlen() function to the net
backend API. The new function allows the virtio-net receive code
to know in advance how many virtio descriptors chains will be
needed to receive the next packet. As a result, the implementation
of the virtio-net mergeable rx buffers feature becomes efficient,
so that we can enable it also with the tap(4) backend. For the
tap(4) backend, a bounce buffer is introduced to implement the
peeck_recvlen() callback, which implies an additional packet copy
on the receive datapath. In the future, it should be possible to
remove the bounce buffer (and so the additional copy), by
obtaining the length of the next packet from kevent data.

ACPI Control Method Batteries have a _BIF and/or _BIX object which
provide static properties of the battery. FreeBSD acpi_cmbat module
supported _BIF object only, which was deprecated as of ACPI 4.0.
_BIX is an extended version of _BIF defined in ACPI 4.0 or later.
As of writing, _BIX has two revisions. One is in ACPI 4.0 (rev.0) and
another is in ACPI 6.0 (rev.1). It seems that hardware vendors still
stick to _BIF only or _BIX rev.0 + _BIF for the maximum compatibility.
Microsoft requires _BIX rev.0 for Windows machines, so there are some
laptop machines with _BIX rev.0 only. In this case, FreeBSD does not
recognize the battery information.
After this change, the acpi_cmbat module gets battery information from
_BIX or _BIF object and internally uses _BIX rev.1 data structure as
the primary information store in the kernel. ACPIIO_BATT_GET_BI[FX]
returns an acpi_bi[fx] structure built by using information obtained
from a _BIF or a _BIX object found on the system. The revision number
field can be used to check which field is available. The acpiconf(8)
utility will show additional information if _BIX is available.
Although ABIs of ACPIIO_BATT_* were changed, the existing APIs for
userland utilities are not changed and the backward-compatible ABIs
are provided. This means that older versions of acpiconf(8) can also
work with the new kernel. The (union acpi_battery_ioctl_arg) was
padded to 256 byte long to avoid another ABI change in the future.
A _BIX object with its revision number >1 will be treated as
compatible with the rev.1 _BIX format.

In order to do so we need to install the msdosfs headers to the bootstrap
sysroot and avoid includes of kernel headers that may not exist on every

on FreeBSD 11+ as well as Linux and macOS.
We also have to avoid using the IO_SYNC macro since that may not be
available. In makefs it is only used to switch between calling
bwrite() and bdwrite() which both call the same function. Therefore we
can simply always call bwrite().
For our CheriBSD builds we always bootstrap makefs by setting

Extended attribute values can potentially be quite large. One test for ZFS
is supposed to set a 200MB xattr. However, the buffer size for reading
values from stdin with setextattr -i is so small that the test times out
waiting for tiny chunks of data to be buffered and appended to an sbuf.
Increasing the buffer size should help alleviate some of the burden of
reallocating larger sbufs when writing large extended attributes.
