while developing and compiling with kernel options that change the
size of at least one structure. The current kernel build framework
does not allow us to pass -Dxxx to module builds so we would possibly
need a kernel option to disable the checks and that might not work
for people just building modules alone.
For now they helped to identify possibly API problems and bring
those back into minds of developers seeking for better solutions.

Clang disallows structs with variable length arrays to be nested inside
other structs, because this is in violation with ISO C99. Even though we
can keep bugging the LLVM folks about this issue, we'd better just fix
our code to not do this. This code seems to be the only code in the
entire source tree that does this.
I haven't tested this patch by using the kernel modules in question, but
Diane Bruce and I have compared disassembled versions of these kernel
modules. We would have expected them to be exactly the same, but due to
randomness in the register allocator and reordering of instructions,
there were some minor differences.

wrapper macros that allow trace points and arguments to be declared
using a single macro rather than several. This means a lot less
repetition and vertical space for each trace point.
Use these macros when defining privilege and MAC Framework trace points.

A while back, Warner changed the PCI bus code to reserve resources when
enumerating devices and simply give devices the previously allocated
resources when they call bus_alloc_resource(). This ensures that address
ranges being decoded by a BAR are always allocated in the nexus0 device
(or whatever device the PCI bus gets its address space from) even if a
device driver is not attached to the device. This patch extends this
behavior further:
- To let the PCI bus distinguish between a resource being allocated by
a device driver vs. merely being allocated by the bus, use
rman_set_device() to assign the device to the bus when it is owned
by the bus and to the child device when it is allocated by the child
device's driver. We can now prevent a device driver from allocating
the same device twice. Doing so could result in odd things like
allocating duplicate virtual memory to map the resource on some
archs and leaking the original mapping.
- When a PCI device driver releases a resource, don't pass the request
all the way up the tree and release it in the nexus (or similar device)
since the BAR is still active and decoding. Otherwise, another device
could later allocate the same range even though it is still in use.
Instead, deactivate the resource and assign it back to the PCI bus
using rman_set_device().
- pci_delete_resource() will actually completely free a BAR including
attemping to disable it.
- Disable BAR decoding via the command register when sizing a BAR in
pci_alloc_map() which is used to allocate resources for a BAR when
the BIOS/firmware did not assign a usable resource range during boot.
This mirrors an earlier fix to pci_add_map() which is used when to
size BARs during boot.
- Move the activation of I/O decoding in the PCI command register into
pci_activate_resource() instead of doing it in pci_alloc_resource().
Previously we could actually enable decoding before a BAR was
initialized via pci_alloc_map().

RH0 was deprecated by RFC 5095.
While most of the code had been disabled by #if 0 already, leave a
bit of infrastructure for possible RH2 code and a log message under
BURN_BRIDGES in case a user still tries to send RH0 packets.

vfsopt and the vfs_buildopts function public, and add some new fields
to struct vfsopt (pos and seen), and new functions vfs_getopt_pos and
vfs_opterror.
Further extend the interface to allow reading options from the kernel
in addition to sending them to the kernel, with vfs_setopt and related
functions.
While this allows the "name=value" option interface to be used for more
than just FS mounts (planned use is for jails), it retains the current
"vfsopt" name and <sys/mount.h> requirement.

This addresses interrupt storms that were noticed after enabling MSI
in drm. I think this is due to a loose interpretation of the PCI 2.3
spec, which states that a function using MSI is prohibitted from using
INTx. It appears that some vendors interpretted that to mean that they
should handle it in hardware, while others felt it was the drivers
responsibility.
This fix will also likely resolve interrupt storm related issues with
devices other than drm.

OpenBSM 1.1 beta 1
- The filesz parameter in audit_control(5) now accepts suffixes: 'B' for
Bytes, 'K' for Kilobytes, 'M' for Megabytes, and 'G' for Gigabytes.
For legacy support no suffix defaults to bytes.
- Audit trail log expiration support added. It is configured in
audit_control(5) with the expire-after parameter. If there is no
expire-after parameter in audit_control(5), the default, then the audit
trail files are not expired and removed. See audit_control(5) for
more information.
- Change defaults in audit_control: warn at 5% rather than 20% free for audit
partitions, rotate automatically at 2mb, and set the default policy to
cnt,argv rather than cnt so that execve(2) arguments are captured if
AUE_EXECVE events are audited. These may provide more usable defaults for
many users.
- Use au_domain_to_bsm(3) and au_socket_type_to_bsm(3) to convert
au_to_socket_ex(3) arguments to BSM format.
- Fix error encoding AUT_IPC_PERM tokens.
