An NFSv4 only configuration does not register with
rpcbind(). Without this patch a failure to rpcb_unset()
is reported when the daemon is terminated for this case.
This is harmless noise, but this patch avoids calling
rpcb_unset() for the NFSv4 only case, avoiding the noise.
When called with "-d", it still does the rpcb_unset(),
assuming that the configuration might have been
changed to NFSv4 only and unregistering with
rpcbind() might still be needed.

This doesn't seem to be the desired behavior because that prevents

If the disk parameter "DEFAULT" is set in place of an actual device name,
or no disk is specified for the PARTITIONS parameter, the installer will
follow the logic used in the automatic-partitioning mode, in which it
will either provide a selection dialog for one of several disks if
several are present or automatically select it if there is only one. This
simplifies the creation of fully-automatic installation media for

There are scenarios where an NFS client will mount an NFSv4 export

When running nfsdumpstate under this circumstance, the column output is

"device" is already used as the generic PCI-level name of the device
model to use (e.g. "hostbridge"). The result was that parsing
"hostbridge" as an integer failed and the host bridge used a device ID

Because the ESP mount point (/boot/efi) is in mtree, tar will attempt to
extract a directory at that point post-mount when the system is installed.
Normally, this is fine, since tar can happily set whatever properties it
wants. For FAT32 file systems, however, like the ESP, tar will attempt to
set mtime on the root directory, which FAT does not support, and tar will
interpret this as a fatal error, breaking the install (see
https://github.com/libarchive/libarchive/issues/1516). This issue would
also break scripted installs on bare-metal POWER8, POWER9, and PS3
systems, as well as some ARM systems.
This patch solves the problem in two ways:
- If stdout is a TTY, use the distextract stage instead of tar, as in
interactive installs. distextract solves this problem internally and
provides a nicer UI to boot, but requires a TTY.
- If stdout is not a TTY, use tar but, as a stopgap for 13.0, exclude
boot/efi from tarball extraction and then add it by hand. This is a
hack, and better solutions (as in the libarchive ticket above) will
obsolete it, but it solves the most common case, leaving only
unattended TTY-less installs on a few tier-2 platforms broken.
In addition, fix a bug with fstab generation uncovered once the tar issue
is fixed that umount(8) can depend on the ordering of lines in fstab in a
way that mount(8) does not. The partition editor now writes out fstab in
mount order, making sure umount (run at the end of scripted, but not
interactive, installs) succeeds.

- There is no need to do anything with gpart (the installer does that

- There is no need to specify the network interface, since we have
an option for defaults.
The header specifies the size of the option in multiples of eight bytes.
The option consists of an eight-byte header followed by one or more IPv6
addresses, so the option is invalid if the size is not equal to 1+2n for
some n>0. Check this.
The bug can cause random stack data to be formatted as an IPv6 address

We want to allow the UEFI firmware to enumerate and assign

assignment of PCI BARs is properly handled by the PCI emulation
code in general, but a few specific cases need additional support.
fbuf and passthru map additional objects into the guest physical
address space and so need to handle address updates. Here we add a
callback to emulated PCI devices to inform them of a BAR
configuration change. fbuf and passthru then watch for these BAR
changes and relocate the frame buffer memory segment and passthru
device mmio area respectively.
We also add new VM_MUNMAP_MEMSEG and VM_UNMAP_PPTDEV_MMIO ioctls

Replace the existing ad-hoc configuration via various global variables
with a small database of key-value pairs. The database supports
heirarchical keys using a MIB-like syntax to name the path to a given
key. Values are always stored as strings. The API used to manage
configuation values does include wrappers to handling boolean values.
Other values use non-string types require parsing by consumers.
The configuration values are stored in a tree using nvlists. Leaf
nodes hold string values. Configuration values are permitted to
reference other configuration values using '%(name)'. This permits
constructing template configurations.
All existing command line arguments now set configuration values. For
devices, the "-s" option parses its option argument to generate a list
of key-value pairs for the given device.
A new '-o' command line option permits setting an individual
configuration variable. The key name is always given as a full path
of dot-separated components.
A new '-k' command line option parses a simple configuration file.
This configuration file holds a flat list of 'key=value' lines where
the 'key' is the full path of a configuration variable. Lines
starting with a '#' are comments.
In general, bhyve starts by parsing command line options in sequence
and applying those settings to configuration values. Once this is
complete, bhyve then begins initializing its state based on the
configuration values. This means that subsequent configuration
options or files may override or supplement previously given settings.
A special 'config.dump' configuration value can be set to true to help
debug configuration issues. When this value is set, bhyve will print
out the configuration variables as a flat list of 'key=value' lines.
Most command line argments map to a single configuration variable,
e.g. '-w' sets the 'x86.strictmsr' value to false. A few command
line arguments have less obvious effects:
- Multiple '-p' options append their values (as a comma-seperated
list) to "vcpu.N.cpuset" values (where N is a decimal vcpu number).
- For '-s' options, a pci.<bus>.<slot>.<function> node is created.
The first argument to '-s' (the device type) is used as the value of
a "device" variable. Additional comma-separated arguments are then
parsed into 'key=value' pairs and used to set additional variables
under the device node. A PCI device emulation driver can provide
its own hook to override the parsing of the additonal '-s' arguments
after the device type.
After the configuration phase as completed, the init_pci hook
then walks the "pci.<bus>.<slot>.<func>" nodes. It uses the
"device" value to find the device model to use. The device
model's init routine is passed a reference to its nvlist node
in the configuration tree which it can query for specific
variables.
The result is that a lot of the string parsing is removed from
the device models and centralized. In addition, adding a new
variable just requires teaching the model to look for the new
variable.
- For '-l' options, a similar model is used where the string is
parsed into values that are later read during initialization.
One key note here is that the serial ports use the commonly
used lowercase names from existing documentation and examples
(e.g. "lpc.com1") instead of the uppercase names previously
used internally in bhyve.

Recent changes have made it such that attaching to a jail will augment
the attaching process' cpu mask with the jail's cpuset. While this is
convenient for allowing the administrator to cpuset arbitrary programs
that will attach to a jail, this is decidedly not convenient for
executing long-running daemons during jail creation.
This change inserts a reset of the process cpuset to the root cpuset
between the fork and attach to execute a command. This allows commands
executed to have the widest mask possible, and the administrator can
cpuset(1) it back down inside the jail as needed.
With this applied, one should be able to change a jail's cpuset at
exec.poststart in addition to exec.created. The former was made
difficult if jail(8) itself was running with a constrained set, as then
some processes may have been spawned inside the jail with a non-root
set. The latter is the preferred option so that processes starting in
