when au_user_mask() fails, it's not a failure to set the audit mask,
but to calculate the audit mask -- and hence a condfiguration-file
issue (of some sort).

to create a repo during 'make packages'
This would have been useful for a situation I found myself in where
pkg(8) had been upgraded to a version that wanted the FBSD_1.5 ABI
version but libc.so.7 had not been upgraded, and only provided
FBSD_1.4. I found I needed to update libc in order to run pkg, and I
also needed to use pkg to update libc... Which is why pkg-static
exists, but there's currently no way to tell the build system to use
pkg-static instead of pkg.
This creates a variable PKG_CMD, default value 'pkg', that can be
overridden from the command line.

Attempt to fix powerpc64 LINT kernel broken by r308000. Netmap's use of
a uint64_t wchan seems odd, but in the interest of minimizing this
change just cast through uintptr_t to silence the compiler warning.

The TCP server implementation in dbgport does not track clients, so it
may try to write to a disconected socket resulting in SIGPIPE.
Avoid that by setting SO_NOSIGPIPE socket option.
Because dbgport emulates an I/O port to guest, the communication is done
byte by byte. Reduce latency of the TCP/IP transfers by using
TCP_NODELAY option. In my tests that change improves performance of
kgdb commands with lots of output (e.g. info threads) by two orders of
magnitude.
A general note. Since we have a uart emulation in bhyve, that can be
used for the console and gdb access to guests. So, bvmconsole and bvmdebug
could be de-orbited now. But there are many existing deployments that
still dependend on those.

passing it to firmware for all Gen3 controllers.
For Thunderbolt controller, keep the legacy behavior i.e. return the SYNCHRONIZE_CACHE command with success status from driver itself.
There is Sysctl parameter 'block_sync_cache' is provided to enable customers either to block/unblock these commands to facilitate
legacy behavior if there is a compatibility issue. Default value for module parameter is to unblock this command.

If a SCSI IO times out, then before initiating OCR, now the driver will try to send a
target reset to the particular target for which the IO is timed out. If that also fails,
then the driver will initiate OCR.

MFI linked list in megaraid_sas driver is used for mfi-mpt pass-through commands.
This list can be corrupted due to many possible race conditions in driver and
eventually we may see kernel panic.
One example -
MFI frame is freed from calling process as driver send command via polling method and interrupt
for that command comes after driver free mfi frame (actually even after some other context reuse
the mfi frame). When driver receive MPT frame in ISR, driver will be using the index of MFI and
access that MFI frame and finally in-used MFI frames list will be corrupted.
High level description of new solution -
Free MFI and MPT command from same context.
Free both the command either from process (from where mfi-mpt pass-through was called) or from
ISR context. Do not split freeing of MFI and MPT, because it creates the race condition which
will do MFI/MPT list.

Clear the interrupt state before reading the input char from the
input FIFO. In the current code there is a window between the read
to the data register and the write to the the ICR, during which an
input char will not cause an interrupt.
This fixes the issue by which the serial port input on QEMU freezes
when using the emulated pl011 serial port.
This allows pw(8) to operate on passwd and group files with longer lines
than could be accomodated by a stack buffer. It doesn't take more than a
few hundred users to exceed 8192 bytes in /etc/group.
