This includes lines referring to nonexistent username/group for log

With this fix, newsyslog uses warnx() instead of errx() in such cases
to print a warning, recover gracefully and continue with execution.

Without this patch, if a SIGHUP is handled while the process is executing
get_exportlist(), that SIGHUP is essentially ignored because the got_sighup

This results in the exports file(s) not being reloaded until another SIGHUP

This patch fixes this by resetting got_sighup to zero before the

It also defines a delay time of 250msec before doing another exports reload

Save and restore (also known as suspend and resume) permits a snapshot
to be taken of a guest's state that can later be resumed. In the
current implementation, bhyve(8) creates a UNIX domain socket that is
used by bhyvectl(8) to send a request to save a snapshot (and
optionally exit after the snapshot has been taken). A snapshot
currently consists of two files: the first holds a copy of guest RAM,
and the second file holds other guest state such as vCPU register
values and device model state.
To resume a guest, bhyve(8) must be started with a matching pair of
command line arguments to instantiate the same set of device models as
well as a pointer to the saved snapshot.
While the current implementation is useful for several uses cases, it
has a few limitations. The file format for saving the guest state is
tied to the ABI of internal bhyve structures and is not
self-describing (in that it does not communicate the set of device
models present in the system). In addition, the state saved for some
device models closely matches the internal data structures which might
prove a challenge for compatibility of snapshot files across a range
of bhyve versions. The file format also does not currently support
versioning of individual chunks of state. As a result, the current
file format is not a fixed binary format and future revisions to save
and restore will break binary compatiblity of snapshot files. The
goal is to move to a more flexible format that adds versioning,
etc. and at that point to commit to providing a reasonable level of
compatibility. As a result, the current implementation is not enabled
by default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes option
for userland builds, and the kernel option BHYVE_SHAPSHOT.

With the inclusion of caroot bits, we'll need to also rehash on update as we
do in mergemaster/etcupdate.
If certctl's installed on the system, just unconditionally rehash. This
isn't an expensive operation, and we can refine it to compare
INDEX-{OLD,NEW} later if we really want to.

Print the failed instruction stream as a contiguous stream of hex. This

0xHH.
Also, use the debug.h 'raw' stdio-aware printf helper to avoid the
cascading

effect.
Add an implementatation of the 'Virtual Machine Generation ID' spec to
Bhyve. The spec provides a randomly generated GUID (at bhyve start) in
device memory, along with an ACPI device with _CID VM_Gen_Counter and ADDR
evaluating to a Package pointing at that GUID.
A GPE is defined which Notifies the ACPI Device when the generation changes
(such as when a snapshot is rolled back). At this time, Bhyve does not
support snapshotting, so the GPE is never actually raised.

To allow more general use of the bootrom region, separate initialization from
allocation, and allocation from loading a file.
The bootrom segment is the high 16MB of the low 4GB region.
Each allocation in the segment creates a new mapping with specified protection.
By default, allocation begins at the low end of the range. However, the
BOOTROM_ALLOC_TOP flag is provided to locate a provided bootrom in the high
region it is expected to be in.
The existing ROM-file loading code is refactored to use the new interface.

Recently added/changed lines in various kernel configs have caused some
buffer overflows that went undetected. These were detected with a config
built using -fno-common as these line buffers smashed one of our arrays,
then further triaged with ASAN.
Double the sizes; this is really not a great fix, but addresses the
immediate need until someone rewrites config. While here, add some bounds
checking so that we don't need to detect this by random bus errors or other
weird failures.

This is mostly two problems spread out far and wide:
- ypldap_process should be declared properly
- debug is defined differently in many programs
For the latter, just extern it and define it everywhere that actually needs
it. This mostly works out nicely for ^/libexec/ypxfr, which can remove the
assignment at the beginning of main in favor of defining it properly.
-fno-common will become the default in GCC10/LLVM11.

Set IFS= for just the read lines to mitigate this, allowing the user to be

As a followup to the use of login.conf environment vars (other than PATH) in
cron, this patch adds PATH (and HOME) to the list of login.conf settings
respected.
The new logic is as follows:
1. SHELL is always _PATH_BSHELL unless explicitly overridden in the crontab
file itself; no other settings are respected. This is unchanged.
2. PATH is taken from the first of: crontab file, login.conf, _PATH_DEFPATH
3. HOME is taken from the first of: crontab file, login.conf, passwd entry,
unset
4. The current directory for invoking the command is taken from the crontab
file's value of HOME (existing behavior), or the passwd entry, but not
anywhere else (so it might not equal HOME if that was set in login.conf).

The SQHD field of a Completion Queue entry indicates the current
Submission Queue head pointer value. The head pointer represents the
next entry to be consumed and is updated after consuming the current
entry.
In the Admin queue processing, the current code updates the head pointer
after reporting the value to the host via the SQHD. This gives the
impression that the Controller is perpetually one command behind in its
processing of the Admin SQ. And while this doesn't appear to bother some
initiators, it is wrong.
Fix is to update the SQ head pointer prior to writing the SQHD value in
the completion.
While here, fix missed update of dword 0 (cdw0) in the completion
message.

The bhyve NVMe emulation has a race in the logic which generates command
completion interrupts. On FreeBSD guests, this manifests as kernel log
messages similar to:
nvme0: Missing interrupt
The NVMe emulation code sets a per-submission queue "busy" flag while
processing the submission queue, and only generates an interrupt when
the submission queue is not busy.
Aside from being counter to the NVMe design (i.e. interrupt properties
are tied to the completion queue) and adding complexity (e.g. exceptions
to not generating an interrupt when "busy"), it causes a race condition
under the following conditions:
- guest OS has no outstanding interrupts
- guest OS submits a single NVMe IO command
- bhyve emulation processes the SQ and sets the "busy" flag
- bhyve emulation submits the asynchronous IO to the backing storage
- IO request to the backing storage completes before the SQ processing
loop exits and doesn't generate an interrupt because the SQ is "busy"
- bhyve emulation finishes processing the SQ and clears the "busy" flag
Fix is to remove the "busy" flag and generate an interrupt when the CQ
head and tail pointers do not match.

the namespace supports delete (i.e. deallocate), setting the deallocate
attribute in a DSM will trim/delete the requested LBA ranges in the
underlying storage.
