up the device described by the nomatch event in the device tree. If we
find it, then if the device is marked as have already attached to a
device once, then ignore the device.
This keeps us from reloading the device driver when it has just been
manually unloaded. All devies that have had a driver attach to them at
least once no longer participate in pnp-based autoloading.
Differential Revision: https://reviews.freebsd.org/D16735
This flag is set once the device has been successfully attached. When
set, it inhibits devmatch from trying to match the device. This in
turn allows kldunload to work as expected. Prior to the change, the
driver would immediately reload because devmatch had no notion that
the driver had once been attached, and therefore shouldn't participate
in further matching.

Add a -U flag to get back the old behavior. The new behavior is a little
more friendly to the common use cases, jail the BE and execute a script.
Having the jail torn down automatically when the script is finished, or when
you exit the shell, is a little more friendly than having to remember to
`bectl ujail`.
Batch mode (-b) will continue to leave the jail up, as it's assumed the
caller has other intentions.

When attempting to document the changed argument types in devstat.9, I
discovered the 20 year old manual page severely mismatched reality even

As indicated by the comment, any fixups applied (which might include
overlays) can invalidate the previously located node by adding nodes or
setting/adding properties. The later fdt_setprop of fixup-applied property
would then fail because of the bad/wrong node offset.
This would have generally been harmless, but potentially caused multiple
applications of fixups and caused a little bit of bloat.

Transferring files in netascii format requires, among other things,
translating all CR characters to a CR,NUL pair. tftpd does this correctly
except when the CR occurs as the last octet of a packet. In that case, it
erroneously drops the NUL which should be part of the following packet. The
bug was caused by using 0 as a sentinel value in a variable that could
legitimately hold 0. Fix it by switching the sentinel value to -1.

Add an option, KASSERT_PANIC_OPTIONAL, that allows runtime KASSERT()
behavior changes. When this option is not enabled, code that allows
KASSERTs to become optional is not enabled, and all violated assertions
cause termination.
The runtime KASSERT behavior was added in r243980.
One important distinction here is that panic has __dead2
("attribute((noreturn))"), while kassert_panic does not. Static analyzers
like Coverity understand __dead2. Without it, KASSERTs go misunderstood,
resulting in many false positives that result from violation of program
invariants.

The boot-time ifunc resolver assumes that it only needs to apply
IRELATIVE relocations to PLT entries. With an upcoming optimization,
this assumption no longer holds, so add the support required to handle
PC-relative relocations targeting GNU_IFUNC symbols.
- Provide a custom symbol lookup routine that can be used in early boot.
The default lookup routine uses kobj, which is not functional at that
point.
- Apply all existing relocations during boot rather than filtering
IRELATIVE relocations.
- Ensure that we continue to apply ifunc relocations in a second pass
when loading a kernel module.

For tools that uses bhyve such like libvirt, it is important to be able to
probe what features are supported by the given bhyve binary.
To give more context, libvirt probes bhyve's capabilities in a not very
effective way:
- Running 'bhyve -h' and parsing output.
- To detect devices, it runs 'bhyve -s 0,dev' for every each device and
parses error output to identify if the device is supported or not.

2^32 bps or greater to be used. Prior to this, bandwidth parameters
would simply wrap at the 2^32 boundary. The computations in the HFSC
scheduler and token bucket regulator have been modified to operate
correctly up to at least 100 Gbps. No other algorithms have been
examined or modified for correct operation above 2^32 bps (some may
have existing computation resolution or overflow issues at rates below
that threshold). pfctl(8) will now limit non-HFSC bandwidth
parameters to 2^32 - 1 before passing them to the kernel.
The extensions to the pf(4) ioctl interface have been made in a
backwards-compatible way by versioning affected data structures,
supporting all versions in the kernel, and implementing macros that
will cause existing code that consumes that interface to use version 0
without source modifications. If version 0 consumers of the interface
are used against a new kernel that has had bandwidth parameters of
2^32 or greater configured by updated tools, such bandwidth parameters
will be reported as 2^32 - 1 bps by those old consumers.
All in-tree consumers of the pf(4) interface have been updated. To
update out-of-tree consumers to the latest version of the interface,
define PFIOC_USE_LATEST ahead of any includes and use the code of
pfctl(8) as a guide for the ioctls of interest.

r334810 introduced zfs_unlinked_drain() dispatch to taskqueue on every
deletion of a file with extended attributes. Using system_taskq for that
with its multiple threads in case of multiple files deletion caused all
available CPU threads to uselessly spin on busy locks, completely blocking
the system.
Use of single dedicated taskqueue is the only easy solution I've found,
while in would be great if we could specify that some task should be
executed only once at a time, but never in parallel, while many tasks
could use different threads same time.

PR#230752 shows a panic where an nfsd thread tries to do soconnect() on
the AF_LOCAL socket used by the nfsuserd while already holding an
exclusive lock on it. I am not 100% sure how this happens, but since an
AF_LOCAL socket is in the file system namespace it is conceivable that it
could lock it and then attempt an upcall to the nfsuserd.
However, reverting r320757 stops the nfsuserd from using an AF_LOCAL
socket, so it should avoid any such panic().
r320757 did fix a problem with running the nfsuserd when jails were
enabled, but that can be dealt with less elegantly by allowing the
use of an alternate address instead of 127.0.0.1.
The gssd daemon also uses an AF_LOCAL socket, but it will do upcalls
before the nfsd thread processes the RPC, so I think it should not
be suseptible to this problem.

This way the target fails if unifdef doesn't exist or doesn't modify the
file instead of just generating an empty .c file.
I found this while building without inherited $PATH (D16815)
Approved By: jhb (mentor)
The current invocation of unifdef causes the build to fail when using a shell
with -o pipefail on by default since unifdef will return a non-zero exit status
if it changes something. The only thing this call to unifdef does is remove 5
lines that will be ignored by the compiler anyway. Furthermore, it is the only
make rule in the source tree that requires unifdef. Removing this call also
makes it slightly easier to build without inhering $PATH (D16815) since we
don't need unifdef anymore.
I also noticed that the sed call to replace the include guard has been broken
for over 10 years since the import of expat 2.0.1 changed it from
`XmlParse_INCLUDED` to `Expat_INCLUDED`. I could also fix this but since it's
been broken for so long and no one noticed, it's probably not necessary.

The original NVMe API used bit-fields to represent fields in data
structures defined by the specification (e.g. the op-code in the command
data structure). The implementation targeted x86_64 processors and
defined the bit fields for little endian dwords (i.e. 32 bits).
This approach does not work as-is for big endian architectures and was
changed to use a combination of bit shifts and masks to support PowerPC.
Unfortunately, this changed the NVMe API and forces #ifdef's based on
the OS revision level in user space code.
This change reverts to something that looks like the original API, but
it uses bytes instead of bit-fields inside the packed command structure.
As a bonus, this works as-is for both big and little endian CPU
architectures.
