wtap: Implement IBSS mode on wtap(4)
For TSF and beacon generation, each STA has to start its local TSF timer

The TSF timer will be used for IBSS merge and beacon frame transmission.
The TSF timer is kept in the HAL of wtap(4). It is working by
continuously updating its value on timer interrupt simulated
by callout_reset().
When receiving beacons, the STA will be merged into the IBSS if
- the STA has the same SSID as the beacon sender
- the STA's TSF timer is smaller than the beacon sender's TSF timer.
After the merging process, the younger STA will be in the IBSS
created by the older STA and the younger STA stops sending beacon
frames. So beacon frames will always be sent by the oldest STA
in IBSS.

two seconds to give the user a chance to read it.
If the FreeBSD kernel is launched directly in a virtual machine rather

user and delay the boot process since the lack of a "hardware" uuid is

LRO: fix BPF filters for lagg in the hpts path
When in the hpts path, we need to handle BPF filters since aggregated
packets do not pass up the stack in the normal way. This is already
done for most interfaces, but lagg needs special handling. This is
because packets received via a lagg are passed up the stack with
the leaf interface's ifp stored in m_pkthdr.rcvif.
To handle lagg packets, we must identify that the passed rcvif is
currently a lagg port by checking for IFT_IEEE8023ADLAG or
IFT_INFINIBANDLAG (since lagg changes the lagg port's type to that
when an interface becomes a lagg member). Then we need to find the
lagg's ifp, and handle any BPF listeners on the lagg.
Note: It is possible to have multiple BPF filters, one on a member
port and one on the lagg itself. That is why we have to have 2
checks and 2 ETHER_BPF_MTAPs.

Explicitly initialize rather than reading newly allocated UFS inodes.
The function ffs_vgetf() is used to find or load UFS inodes into a
vnode. It first looks up the inode and if found in the cache its
vnode is returned. If it is not already in the cache, a new vnode
is allocated and its associated inode read in from the disk. The
read is done even for inodes that are being initially created.
The contents for the inode on the disk are assumed to be empty. If
the on-disk contents had been corrupted either due to a hardware
glitch or an agent deliberately trying to exploit the system, the
UFS code could panic from the unexpected partially-allocated inode.
Rather then having fsck_ffs(8) verify that all unallocated inodes
are properly empty, it is easier and quicker to add a flag to
ffs_vgetf() to indicate that the request is for a newly allocated
inode. When set, the disk read is skipped and the inode is set to
its expected empty (zero'ed out) initial state. As a side benefit,
an unneeded disk I/O is avoided.

Move the ability to search for alternate UFS superblocks from fsck_ffs(8)
into ffs_sbsearch() to allow use by other parts of the system.
Historically only fsck_ffs(8), the UFS filesystem checker, had code
to track down and use alternate UFS superblocks. Since fsdb(8) used
much of the fsck_ffs(8) implementation it had some ability to track
down alternate superblocks.
This change extracts the code to track down alternate superblocks
from fsck_ffs(8) and puts it into a new function ffs_sbsearch() in
sys/ufs/ffs/ffs_subr.c. Like ffs_sbget() and ffs_sbput() also found
in ffs_subr.c, these functions can be used directly by the kernel
subsystems. Additionally they are exported to the UFS library,
libufs(8) so that they can be used by user-level programs. The new
functions added to libufs(8) are sbfind(3) that is an alternative
to sbread(3) and sbsearch(3) that is an alternative to sbget(3).
See their manual pages for further details.
The utilities that have been changed to search for superblocks are
dumpfs(8), fsdb(8), ffsinfo(8), and fsck_ffs(8). Also, the prtblknos(8)
tool found in tools/diag/prtblknos searches for superblocks.
The UFS specific mount code uses the superblock search interface
when mounting the root filesystem and when the administrator doing
a mount(8) command specifies the force flag (-f). The standalone UFS
boot code (found in stand/libsa/ufs.c) uses the superblock search
code in the hope of being able to get the system up and running so
that fsck_ffs(8) can be used to get the filesystem cleaned up.
The following utilities have not been changed to search for
superblocks: clri(8), tunefs(8), snapinfo(8), fstyp(8), quot(8),
dump(8), fsirand(8), growfs(8), quotacheck(8), gjournal(8), and
glabel(8). When these utilities fail, they do report the cause of
the failure. The one exception is the tasting code used to try and
figure what a given disk contains. The tasting code will remain
silent so as not to put out a slew of messages as it trying to taste
every new mass storage device that shows up.

bhyve nvme: Fix out-of-bound IOV array access
Summary:
NVMe operations indicate the memory region(s) associated with a command
via physical region pages (PRPs). Since each PRP has a fixed size,
contiguous memory regions larger than the PRP size require multiple PRP
entries.
Instead of issuing a blockif call for each PRP, the NVMe emulation
concatenates multiple contiguous PRP entries into a single blockif
request. The test for contiguous regions has a bug such that it
mistakenly treats an initial PRP address of zero as a contiguous range
and concatenates it with the previous. But because there is no previous
IOV, the concatenation code corrupts the IO request structure and leads
to a segmentation fault when the blockif request completes.
Fix is to test for the existence of a previous range before trying to
concatenate the current range with the previous one.
While in the area, rename pci_nvme_append_iov_req()'s lba parameter to

positives' for places to omit to reduce the size as well as reducing the
build time slightly.

stand: Compile out the extensive superblock diagnostic messages for BIOS loader
The BIOS loader operates in a very constrained environment. The messages
for the super block integrity tests take up about 12k of space. Compile
them out for the BIOS loader, while leaving it intact for all other
loaders that aren't space constrained. These aren't used in the 'super
tiny' *boot* programs, so no adjustment is needed there.
We reply on the fact that (a) i386 doesn't support 32-bit UEFI booting
and (b) LIBSA_CPUARCH is "i386" when building on both i386 and when
we're building the 32-bit libsa32 library.
This saves about 12k of space for this constrained envrionment and will
take a bit of the pressure off some machines where the loader has grown
too big for their BIOS (see comments in i386/loader/Makefile for
details).

stand: Raise limit to 550,000 bytes for loader
Raise the limit for /boot/loader to be 550k. The IBM PC imposes a limit
of 640k of RAM below 1MB, which is needed for real mode calls. BTX takes
40k of that. The BIOS takes some amount (25k seems a good "99% take less
than or equal to this" estimate for that, though some systems consume
more). Most typical setups need 25k of stack. This leaves 550k for
code. We set the limit to 550,000 which gives about an extra 13,000
bytes of buffer for machines that whose setups use a little more stack
or whose BIOS reserves a bit more...
Add this derivation in the Makefile. Also recommend setting LOADERSIZE
lower in /etc/src.conf when the loader has to run on a system whose BIOS
takes up more space, or for a complex setup. Add a recipe for how to
find how much RAM your BIOS uses as well (thanks to jhb@ for the
trick). Network cards that boot via PXE and HBAs with their BIOS enabled
are known to be large consumers of lomem space.

stand: Go back to a.out format for /boot/loader
Turns out there's two hidden a.out dependencies. pxeldr.S assumes it has
access to the a.out header from /boot/loader and cdboot.S assumes that
/boot/loader is also a.out and doesn't use boot2.
So, go back to making a.out files for these and adjust the size checks
to use ls, but we only need to check loader.bin. Trim the size we check
against by 2,000. The difference in size between loader and loader.bin
is about 3000 bytes, but clang15 produces binaries that are a smidge
bigger so we need to relax the check just a little and accept some
additional risk for the moment.
Add some comments to loader's Makefile about this.

iconv_std: complete the //IGNORE support
Previously, it would only ignore failures due to csmapper conversion
failure. It may be the case that the input string contains invalid
sequences that also need to be ignored.
A good example of //IGNORE application is sanitizing user- or remotely-
specified strings that are expected to be UTF-8; perhaps as part of a
pipeline that will feed the result into a system less tested against or
tolerant of illegal UTF-8 sequences.

libc: iconv: add mb_cur_min for encoder traits
A future commit will actually implement //IGNORE so that applications
using base iconv can, e.g., sanitize UTF-8 strings. To do this, the
iconv_std module needs to be able to determine the minimum width for any
given encoding so that it can skip that many bytes in the input buffer.
This is mainly an issue for UTF-16 and UTF-32.
This commit bumps shlib versions to 5 for libiconv modules to reflect
the ABI change. It also fixes OptionalObsoleteFiles to remove the
libiconv modules if WITHOUT_ICONV is in use.
re: _ENCODING_MB_CUR_MIN, note that this file (citrus_stdenc_template.h)
is included at the bottom of an encoding *implementation*, so the
implementation is free to #define it prior. UTF1632 is a good example,
as it redefines the minimum to be a property on the encodinginfo, and
the minimum is set to 2 or 4 bytes for UTF-16 and UTF-32 respectively.
