By default, makefs(8) has very few spare inodes in its output images,
which is fine for static filesystems, but not so great for VM images
where many more files will be added. Make makefs(8) use the same
default settings as newfs(8) when creating images with free space --
there isn't much point to leaving free space on the image if you
can't put files there. If no free space is requested, use current

An NFSv4 only configuration does not register with

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

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
and passed to resolvconf(8), but a host able to trigger the bug may also
specify arbitrary addresses this way.

We want to allow the UEFI firmware to enumerate and assign
addresses to PCI devices so we can boot from NVMe[1]. Address
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
to vmm(4) to facilitate the unmapping needed for addres updates.

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.
