su isn't the foreground process. Hopefully this won't break PAM,
but I couldn't find any useful information about ache's theory
that it will.
Specifically, this change fixes the following:
# sh
# echo $$
# su - root -c id &
# echo $$
The PID output changes as su seems to be kill -STOP'ing itself
and catching the parent shell in the process. This is especially
bad if you add a ``su - user -c command &'' to an rc script!

type which is a String type that has no -s limitations applied to it.
Change most Strings in the code to Names and add a few extra syscalls,
namely munmap, read, rename and symlink. This was enough to facilitate
following file descriptor allocations in the code more easily and
getting a hint at what's being read/written from/to files. More
syscalls should really be added.
While here, fix an off-by-one bug in the buffer truncation code and
add a fflush so that truss's output reflects the syscall that the
program is stuck in.

disk. Apparently some people want to use mdmfs as mount_* as a
shortcut for mounting existing file-based file systems.
Note that unlike in the patches from the submitters, this option is
not available in compat mode. Compat mode was supposed to support only
things that mount_mfs used to support. To use this option from fstab,
mdmfs should be called mount_md, not mount_mfs. This distinction has
not always upkept for new options, and those can't be fixed now
without breaking people's systems, but new options should not usually
be allowed in compat mode. (Not sure why -F is allowed there at all.)

- provide an interface (macros) to the page coloring part of the VM system,
this allows to try different coloring algorithms without the need to
touch every file [1]
- make the page queue tuning values readable: sysctl vm.stats.pagequeue
- autotuning of the page coloring values based upon the cache size instead
of options in the kernel config (disabling of the page coloring as a
kernel option is still possible)
MD changes:
- detection of the cache size: only IA32 and AMD64 (untested) contains
cache size detection code, every other arch just comes with a dummy
function (this results in the use of default values like it was the
case without the autotuning of the page coloring)
- print some more info on Intel CPU's (like we do on AMD and Transmeta
CPU's)
Note to AMD owners (IA32 and AMD64): please run "sysctl vm.stats.pagequeue"
and report if the cache* values are zero (= bug in the cache detection code)
or not.

but don't expect a proper ASCII string to exist right here right now, don't
use strcmp(3) which checks for a NUL. As we're still building the argument
up, the next character might be garbage. It would probably be just as safe to
temporarily write a NUL there, but if we've reached the end of argument memory
that might not be the best idea, I think. It's unclear.
Doing it this way seems to meet the most with the original intent.

security.mac.biba.interfaces_equal
If non-zero, all network interfaces be created with the label:
biba/equal(equal-equal)
This is useful where programs which initialize network interfaces
do not have any labeling support. This includes dhclient and ppp. A
long term solution is to add labeling support into dhclient(8)
and ppp(8), and remove this variable.
It should be noted that this behavior is different then setting the:
security.mac.biba.trust_all_interfaces
sysctl variable, as this will create interfaces with a biba/high label.
Lower integrity processes are not able to write to the interface in this
event. The security.mac.biba.interfaces_equal will override
trust_all_interfaces.
The security.mac.biba.interfaces_equal variable will be set to zero
or disabled by default.

pci_add_map. Write new value of allocated resource into the bar, if
the allocation succeeded (we should have done this before, but with
the new force the bug was very obvious).
