Notes:
This value is not sanity checked in bsd.sys.mk, however, given the two

Add or fix options to control static and dynamic configuration. Keep
the default of scteken, but default to statically configuring all available
emulators (now 3 instead of 1).
The dumb emulator is almost usable. libedit and libreadline handle
dumb terminals perfectly for at least shell history. less(1) works
as well as possible except on exit. But curses programs make messes.
The dumb emulator has strange color support, with 2 dumb colors for
normal output but fancy colorization for the cursor, mouse pointer and
(with a non-dumb initial emulator) for low-level console output.
Using the sc emulator instead of the default of scteken fixes at least
the following bugs:
- NUL is a printing character in cons25 but not in teken
- teken doesn't support fixed colors for "reverse" video.
- The best versions of sc are about 10 times faster than scteken (for
printing to the frame buffer). This version is only about 5 times
faster.
Fix configuration features:
- make SC_DFLT_TERM (for setting the initial emulator) a normal option.
Add configuration features:
- negative options SC_NO_TERM_* for omitting emulators in the static config.
Modules for emulators might work, but I don't know of any
- vidcontrol -e shows the available emulators
- vidcontrol -E <emulator> sets the active emulator.
Specifically, I put the new option line in the wrong place, and then fixed
up the rest without realizing it. This puts the usage statement back to
what it was, with an additional line for the new -V option.

While the warning is a false positive, it is possible to clarify the code by

These programs parse ND6 Router Advertisement messages; rtsold(8) has
required an SA, SA-14:20.rtsold, for a bug in this code. Thus, they
are good candidates for sandboxing.
The approach taken is to run the main executable in capability mode
and use Casper services to provide functionality that cannot be
implemented within the sandbox. In particular, several custom services
were required.
- A Casper service is used to send Router Solicitation messages on a
raw ICMP6 socket. Initially I took the approach of creating a
socket for each interface upon startup, and connect(2)ing it to
the all-routers multicast group for the interface. This permits
the use of sendmsg(2) in capability mode, but only works if the
interface's link is up when rtsol(d) starts. So, instead, the
rtsold.sendmsg service is used to transmit RS messages on behalf
of the main process. One could alternately define a service
which simply creates and connects a socket for each destination
address, and returns the socket to the sandboxed process. However,
to implement rtsold's -m option we also need to read the ND6 default
router list, and this cannot be done in capability mode.
- rtsold may execute resolvconf(8) in response to RDNSS and DNSSL
options in received RA messages. A Casper service is used to
fork and exec resolvconf(8), and to reap the child process.
- A service is used to determine whether a given interface's
link-local address is useable (i.e., not duplicated or undergoing
DAD). This information is supplied by getifaddrs(3), which reads
a sysctl not available in capability mode. The SIOCGIFCONF socket
ioctl provides equivalent information and can be used in capability
mode, but I decided against it for now because of some limitations
of that interface.
In addition to these new services, cap_syslog(3) is used to send
messages to syslogd.

Many size / length parameters in NVMe are "0's based", meaning, a value
of 0x0 represents 1, 0x1 represents 2, etc.. While this leads to an
efficient encoding, it can lead to subtle bugs. With respect to queues,
these parameters include:
- Maximum number of queue entries
- Maximum number of queues
- Number of Completion Queues
- Number of Submission Queues
To be consistent, convert all 0's based values from the host to 1's
based value internally. Likewise, covert internal 1's based values to
0's based values when returned to the host. This fixes an off-by-one bug
when creating IO queues and simplifies some of the code. Note that this
bug is masked by another bug.

When using a gmirror, entries in /dev can be removed. So instead of using
kern.disks, get the list of disks from "gpart status -sg" instead.
We assume that any 'efi' partition that can't be mounted as msdosfs should
be used as an ESP. However, the ESP on the CD/DVD can't be mounted read-write
and so was being treated as if unformatted. Try the mount as read-only
instead, to catch cases like this.

config(8)'s option handling has been written to allow duplicate options; if
the value changes, then the latest value is used and an informative message
is printed to stderr like so:
/usr/src/sys/amd64/conf/TEST: option "VERBOSE_SYSINIT" redefined from 0 to 1
Currently, this is only a possibility for cpu types, MAXUSERS, and
MACHINE_ARCH. Anything else duplicated in a config file will use the first
value set and error about duplicated options on subsequent appearances,
which is arguably unfriendly since one could specify:
include GENERIC
nooptions VERBOSE_SYSINIT
options VERBOSE_SYSINIT
to redefine the value later anyways.

-s 6,virtio-scsi,dev=/dev/cam/ctl2.3
If neither is specified, the default /dev/cam/ctl device is used.

superblock has a check-hash error, an error message noting the
superblock check-hash failure is printed and the mount fails. The
administrator then runs fsck to repair the filesystem and when
successful, the filesystem can once again be mounted.
This approach fails if the filesystem in question is a root filesystem
from which you are trying to boot. Here, the loader fails when trying
to access the filesystem to get the kernel to boot. So it is necessary
to allow the loader to ignore the superblock check-hash error and make
a best effort to read the kernel. The filesystem may be suffiently
corrupted that the read attempt fails, but there is no harm in trying
since the loader makes no attempt to write to the filesystem.
Once the kernel is loaded and starts to run, it attempts to mount its
root filesystem. Once again, failure means that it breaks to its prompt
to ask where to get its root filesystem. Unless you have an alternate
root filesystem, you are stuck.
Since the root filesystem is initially mounted read-only, it is
safe to make an attempt to mount the root filesystem with the failed
superblock check-hash. Thus, when asked to mount a root filesystem
with a failed superblock check-hash, the kernel prints a warning
message that the root filesystem superblock check-hash needs repair,
but notes that it is ignoring the error and proceeding. It does
mark the filesystem as needing an fsck which prevents it from being
enabled for writing until fsck has been run on it. The net effect
is that the reboot fails to single user, but at least at that point
the administrator has the tools at hand to fix the problem.

node is set, allow setting security.bsd.unprivileged_proc_debug per-jail.
In part, this is needed to create jails in which the Address Sanitizer
(ASAN) fully works as ASAN utilizes libkvm to inspect the virtual address
space. Instead of having to allow unprivileged process debugging for the
entire system, allow setting it on a per-jail basis.
The sysctl node is still security.bsd.unprivileged_proc_debug and the
jail(8) param is allow.unprivileged_proc_debug. The sysctl code is now a
sysctl proc rather than a sysctl int. This allows us to determine setting
the flag for the corresponding jail (or prison0).
As part of the change, the dynamic allow.* API needed to be modified to
take into account pr_allow flags which may now be disabled in prison0.
This prevents conflicts with new pr_allow flags (like that of vmm(4)) that
are added (and removed) dynamically.
Also teach the jail creation KPI to allow differences for certain pr_allow
flags between the parent and child jail. This can happen when unprivileged
process debugging is disabled in the parent prison, but enabled in the
child.

This change defines the RA "6" (IPv6-Only) flag which routers
may advertise, kernel logic to check if all routers on a link
have the flag set and accordingly update a per-interface flag.
If all routers agree that it is an IPv6-only link, ether_output_frame(),
based on the interface flag, will filter out all ETHERTYPE_IP/ARP
frames, drop them, and return EAFNOSUPPORT to upper layers.
The change also updates ndp to show the "6" flag, ifconfig to
display the IPV6_ONLY nd6 flag if set, and rtadvd to allow
announcing the flag.
Further changes to tcpdump (contrib code) are availble and will
be upstreamed.
Tested the code (slightly earlier version) with 2 FreeBSD
IPv6 routers, a FreeBSD laptop on ethernet as well as wifi,
and with Win10 and OSX clients (which did not fall over with
the "6" flag set but not understood).
We may also want to (a) implement and RX filter, and (b) over
time enahnce user space to, say, stop dhclient from running
when the interface flag is set. Also we might want to start
IPv6 before IPv4 in the future.
All the code is hidden under the EXPERIMENTAL option and not
compiled by default as the draft is a work-in-progress and
we cannot rely on the fact that IANA will assign the bits
as requested by the draft and hence they may change.
