36c51ae068 Check key size for rijndael, as invalid key size can lead to kernel panic.
It checked other algorithms against this bug and it seems they aren't
affected.

7cf30146f0 - Move IF_ADDR_LOCK_DESTROY(ifp) from if_free to if_free_type.
- Add a note that additions should be made to if_free_type and not
  if_free to help avoid this in the future.

This apparently fixes a use after free in if_bridge and may fix bugs
in other direct if_free_type consumers.

1b279bfb52 - Change the code that determines whether to use a serial console and
which serial device to use in that case respectively to not rely on
  the OFW names of the input/output and stdin/stdout devices. Instead
  check whether input and output refers to the same device and is of
  type serial (uart(4) was already doing this) and for the fallback
  to a serial console in case a keyboard is the selected input device
  but unplugged do the same for stdin and stdout in case the input
  device is nonexistent (PS/2 and USB keyboards) or has a 'keyboard'
  property (RS232 keyboards). Additionally also check whether the OFW
  did a fallback to a serial console in the same way in case the
  output device is nonexistent. While at it save on some variables
  and for sys/boot/sparc64/loader/metadata.c move the code in question
  to a new function md_bootserial() so it can be kept in sync with
  uart_cpu_getdev_console() more easily.
  This fixes selecting a serial console and the appropriate device
  when using a device path for the 'input-device' and 'output-device'
  OFW environment variables instead of an alias for the serial device
  to use or when using a screen alias that additionally denotes a
  video mode (like e.g. 'screen:r1024x768x60') but no keyboard is
  plugged in (amongst others). It also makes the code select a serial
  console in case the OFW did the same due to a misconfiguration like
  both 'input-device' and 'output-device' set to 'keyboard' or to a
  nonexisting device (whether the OFW does a fallback to a serial
  console in case of a misconfiguration or one ends up with just no
  console at all highly depends on the OBP version however).
- Reduce the size of buffers that only ever need to hold the string
  'serial' accordingly. Double the size of buffers that may need to
  hold a device path as e.g. '/pci@8,700000/ebus@5/serial@1,400000:a'
  exceeds 32 chars.
- Remove the package handle of the '/options' node from the argument
  list of uart_cpu_getdev_dbgport() as it's unused there and future
  use is also unlikely.

8cc5eb98ad Fix a stupid logic bug introduced in geom_vinum_drive.c rev 1.18:
When a drive is newly created, it's state is initially set to 'down',
so it won't allow saving the config to it (thus it will never know of
itself being created).  Work around this by adding a new flag, that's
also checked when saving the config to a drive.

691cdb5351 Ensure that we are holding the lock when initialising the bridge interface. We
could initialise while unlocked if the bridge is not up when setting the inet
address, ether_ioctl() would call bridge_init.

0c207975f2 Do not keep parent directory locked while calling VFS_ROOT to traverse mount
points in lookup(). The lock can be dropped safely around VFS_ROOT because
LOCKPARENT semantics with child and perent vnodes coming from different FSes
does not really have any meaningful use. On the other hard, this prevents
easily triggered deadlock on systems using automounter daemon.

14dcd40fde - restore the ability to mount cd9660 filesystems as root by inverting
some of the options test, specifically the joliet and rockridge tests.
  Since the root mount callchain doesn't go through cd9660_cmount, the
  default mount options aren't set. Rather than having the main codepath
  assume the options are there, test for the absence of the inverted
  optioin

  e.g. instead of vfs_flagopt(.. "joliet" ..), test for
  !vfs_flagopt(.. "nojoliet" ..)

  This works for root mount, non-root mount and future nmount cases.

- in cd9660_cmount, remove inadvertent setting of "gens" when "extatt"
  was set.

86257f240a Fix the problem with the IPI for the lazy context switching of the
high FP registers. It was not that the IPI got lost due to the
perceived unreliability of the IPI delivery, but rather that the
IPI was not assigned a vector (ugh). Sending a 0 vector to a CPU
results in a stray external interrupt.
Add a KASSERT to ipi_send() to catch this. The initialization of
the IPIs could be better, but it's not at all sure what the future
of the code is. Avoid wasting a lot of time on something that is
going to be rewritten anyway.
