This is a prerequisite to using these functions outside of ddb, but also
provides some cleanup and minor refactoring. This code is almost
entirely duplicated between the two implementations, the only
significant difference being the lack of dbreg synchronization on i386.
Cleanups are:
- demote some internal functions to static
- use the constant NDBREGS instead of a '4' literal
- remove K&R definitions
- some added comments

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.

The decision whether a TCP packet is sent over IPv4 or IPv6 was
based on ethertype, which works correctly. In D27926 the criteria
was changed to checking if the CSUM_IP_TSO flag is set in the
csum-flags and then considering it to be TCP/IPv4.
However, the TCP stack sets the flag to CSUM_TSO for IPv4 and IPv6,
where CSUM_TSO is defined as CSUM_IP_TSO|CSUM_IP6_TSO.
Therefore TCP/IPv6 packets gets mis-classified as TCP/IPv4,
which breaks TSO for TCP/IPv6.
This patch bases the check again on the ethertype.
This fix will be MFC instantly as discussed with re(gjb).

This reverts commit 0af562d7e1.
The global list has a marker with an invariant that free vnodes are
placed somewhere past that. A caller which performs filtering (like ZFS)
can move said marker all the way to the end, across free vnodes which
don't match. Then a caller which does not perform filtering will fail to
find them. This makes vn_alloc_hard sleep for 1 second instead of
reclaiming, resulting in significant stalls.
Fix the problem by requiring an explicit marker by callers which do
filtering.
As a temporary measure extend vnlru_free to restart if it fails to
reclaim anything.
Big thanks go to the reporter for testing several iterations of the

Summary:
This change currently (partially) duplicates AC1 freqbands as AC2
as they are not fully overlapping.
It then adds the 11ac netband to the "etsi" domain including
"indoor" and "dfs" flags, which we can deal with, as well as
appropriate (round down) maxpower values.
Comments are left for the actual frequency bands as we do use the
centerfreq for the first/last (chansep sized) channel in the
freqband and their "id" name, which can be confusing.

Now the default lookup path is
1. base
2. localbase
3. localbase special site for custom terminfo (for ports adding custom
terminfo and avoid potential collision with the general db)
4. termcap
The plan is to allow the terminfo-db to be installed by end users via
a package for people willing to have the support for features from
this database provides. And keep the fallback on termcap for people who
don't want to hear about the terminfo db or how to configure the terminal
if it uses by default the features proposed in the definitions
of the terminfo db.
the first look up path is a window open for a proposal made by glebius@

the feature it want for a given terminal and generate its configurations
based on that. I won't work on it, but it is now posssible and there is

Vulnerability
A vulnerability was discovered in how wpa_supplicant processes P2P
(Wi-Fi Direct) provision discovery requests. Under a corner case
condition, an invalid Provision Discovery Request frame could end up
reaching a state where the oldest peer entry needs to be removed. With
a suitably constructed invalid frame, this could result in use
(read+write) of freed memory. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially code execution.
Vulnerable versions/configurations
wpa_supplicant v1.0-v2.9 with CONFIG_P2P build option enabled
An attacker (or a system controlled by the attacker) needs to be within
radio range of the vulnerable system to send a set of suitably
constructed management frames that trigger the corner case to be reached
in the management of the P2P peer table.
Note: FreeBSD base does not enable P2P.
These ioctl commands aim to provide easier ways for user space
applications to enumerate existing audio devices and the node they can
potentially use.
The exchange of device lists between user space and kernel is done on
nv(9). Some ioctl commands are added to /dev/sndstat node:
- SNDSTAT_REFRESH_DEVS
- SNDSTAT_GET_DEVS
- SNDSTAT_ADD_USER_DEVS
- SNDSTAT_FLUSH_USER_DEVS
