During distributeworld we call distribute on subdirectories, which in
turn calls installconfig. However, this recursive installconfig call
appends the distribution name (in these cases, "base") to DESTDIR. For
install(1) this works fine as its -D argument comes from the top-level
Makefile.inc1, which passes the original DESTDIR, thereby resulting in
the METALOG entry having the distribution name as a prefix representing
its true installed path relative to the root, but for the hand-rolled
entries they do not use install(1) and thus do not have access to what
the original DESTDIR was, resulting in the METALOG missing this prefix.
Thus, pass down the name of the distribution via a new variable DISTBASE
(chosen as Makefile.inc1 already uses that to convey this exact same
information to etc's distrib-dirs during distributeworld) and prepend
this to the handful of manually-generated METALOG entries. For the
installworld case this variable will be empty and so this behaves as
before.
Note that we need to be careful to avoid double slashes in the METALOG;
distributeworld uses find | awk to split the single METALOG up into
multiple dist.meta files, and this relies on the paths in the METALOG
having the exact prefix ./dist (or ./dist/usr/lib/debug).

The nit addressed is that it currently only names the BEs after the

change, we request both and pass them through sort(1) to choose the
highest. This is especially helpful if a freebsd-update patch touched
one but not the other.
The bug fixed is that roots updated that are not located at '/', e.g.,
by using -b or -j, will no longer create boot environments
automatically. There's a very low chance these will actually change the
BE in any meaningful way, anyways. It could make sense in the future
to allow an argument-override to create the BE anyways if someone comes

their boot environment on an appliance or some such setup.

The NVM Format command is unique among the Admin commands in that it
needs to finish asynchronously. For this reason, the emulation code
invented a synthetic completion status (NVME_NO_STATUS) to indicate that
the command was still in progress and the command processing loop should
not generate a completion message. The implementation used the value
0xffff for the synthetic value as this set both the Status Code and
Status Code Type fields to reserved values.
Format initialized the completion status to this value and expected
error cases to override it with a status code/type appropriate to the
situation. The macros used to set the NVMe status are careful not to
modify bit 0 (i.e. the phase bit), which with the synthetic completion
status, causes the phase bit to get out of sync. When running tests in a
guest with illegal NVM Format commands, Admin commands would eventually
hang because it appeared there were no completions due to the incorrect
phase bit value.
Fix is to only set NVME_NO_STATUS if the blockif delete command
succeeds. While in the neighborhood, add a missing break statement when
NVM Format is not supported.

Bhyve allocates small 64 bit BARs below 4 GB and generates ACPI tables
based on this allocation. If the guest decides to relocate those BARs
above 4 GB, it could lead to mismatching ACPI tables. Especially
when using OVMF with enabled bus enumeration it could cause
issues. OVMF relocates all 64 bit BARs above 4 GB. The guest OS
may be unable to recover from this situation and disables some PCI
devices because their BARs are located outside of the MMIO space
reported by ACPI. Avoid this situation by giving the guest more
space for relocating BARs.
Let's be paranoid. The available space for BARs below 4 GB is 512 MB
large. Use a slop of 512 MB. It'll allow the guest to relocate all
BARs below 4 GB to an address above 4 GB. We could run into issues
when we exceeding the memlimit above 4 GB. However, this space has
a size of 32 GB. Even when using many PCI device with large BARs
like framebuffer or when using multiple PCI busses, it's very
unlikely that we run out of space due to the large slop.
Additionally, this situation will occur on startup and not at runtime
which is much better.

At the moment, you only have one single chance to read the fwctl

it switches to REQ. From now on it's impossible to switch back to

driver can read the signature. A guest can't use two drivers to
identify that fwctl is present. It gets even worse when using
OVMF. OVMF uses a library to access fwctl. Therefore, every single
OVMF driver would try to read the signature. Currently, only a
single OVMF driver accesses the fwctl. So, there's no issue with
it yet. However, no OS driver would have a chance to detect fwctl when
using OVMF because it's signature was already consumed by OVMF.

E.g. Framebuffers can require large space and BARs need to be aligned
by their size. If BARs aren't allocated by size, it'll cause much
fragmentation of the MMIO space. Reduce fragmentation by ordering
the BAR allocation on their size to reduce the risk of
OUT_OF_MMIO_SPACE issues.

Shortlinks occupy the space of both di_db and di_ib when used. However,
everywhere that wants to read or write a shortlink takes a pointer do
di_db and promptly runs off the end of it into di_ib. This is fine on
most architectures, if a little dodgy. However, on CHERI, the compiler
can optionally restrict the bounds on pointers to subobjects to just
that subobject, in order to mitigate intra-object buffer overflows, and
this is enabled in CheriBSD's pure-capability kernels.
Instead, clean this up by inserting a union such that a new di_shortlink
can be added with the right size and element type, avoiding the need to
cast and allowing the use of the DIP macro to access the field. This
also mirrors how the ext2fs code implements extents support, with the
exact same structure other than having a uint32_t i_data[] instead of a
char di_shortlink[].

parseDWM() can advance the time to the next week. If the next week is
in the next month, then tm_mon is incremented. However, the increment
was failing to handle the wraparound from December to January, so when
parsing a rule during the last week of the December, the month would
advance to month 12. This triggered an out-of-bounds read of the
mtab[] array in days_pmonth() after parseDWM() returned. To fix,
this change resets the month to January and increment the year when
the month increment wraps.
The default rule for /var/log/weekly.log triggers this during the
last week of December each year.

Text requests and responses can span multiple PDUs. In that case, the
sender sets the Continue bit in non-final PDUs and the Final bit in
the last PDU. The receiver responds to non-final PDUs with an empty
text PDU.
To support this, add a more abstract API in libiscsi which accepts and
receives key sets rather than PDUs. These routines internally send or
receive one or more PDUs. Use these new functions to replace the
handling of TextRequest and TextResponse PDUs in discovery sessions in
both ctld and iscsid.
Note that there is not currently a use case for large Text requests
and those are still always sent as a single PDU. However, discovery
sessions can return a text response listing targets that spans
multiple PDUs, so the new API supports sending and receiving multi-PDU
responses.

The first time we start bhyve with a passthru device everything is fine
as on boot we do enable BARs. If a driver (unload) inside bhyve disables
the BAR(s) as some Linux drivers do, we need to make sure we re-enable
them on next bhyve start.
If we are trying to mmap a disabled BAR for MSI-X (PCIOCBARMMAP)
the kernel will give us an EBUSY.
While we were re-enabling the BAR(s) in the current code loop
cfginit() was writing the changes out too late to the real hardware.
Move the call to init_msix_table() after the register on the real
hardware was updated. That way the kernel will be happy and the
mmap will succeed and bhyve will start.
Also simplify the code given the last argument to init_msix_table()
is unused we do not need to do checks for each bar. [1]

If a "raw" IPv6 address (denoted by a leading '[') is used as a target
address, then 'arg' is incremented by one to skip over the '['.
However, this meant that at the end of the function the wrong address
was passed to free(). With malloc junking enabled and given suitably
small strings, malloc() would happily overwrite the correct number of
bytes with junk, but off by one byte overwriting the byte after the
allocation.
This manifested as the first byte of the 'HeaderDigest' key being
overwritten causing the key name on the wire to be sent as
'\x5eaderDigest' which the target rejected.

This makes option handling consistent with other utilities as well as

its argument are separated by a space or not, so -d5.3 works the same

Also, recognize either /dev/ugen or ugen as prefix to the -d argument.
Note that this removes the undocumented feature that allowed to
specify multiple -d n.m options interleaved with commands referring to
that particular device in a single run.
