Introduce a new option, daily_status_disks_df_flags, which specifies
the command-line arguments to be used for the call to df(1) when
daily_status_disks_enable is set to YES.
The name of the new variable was chosen by the maintainer of our
periodic hierarchy, Brian Somers.
simplify and correct name resolution in tn().
XXX what is the goal of af_switch()? it seems to me it is not necessary
any more with getaddrinfo(3) fix for correct name-resolution ordering.

Support for unsigned integer and long sysctl variables. Update the
SYSCTL_LONG macro to be consistent with other integer sysctl variables
and require an initial value instead of assuming 0. Update several
sysctl variables to use the unsigned types.

Oops! If we're deciding a command is now really dead, make *darned*
sure that it really is by issuing a ISPCTL_ABORT_CMD just on the
off chance the f/w will start it up again and, ha ha, start using
the DMA resources we gave it but are now taking away.
Clean up ISPCTL_ABORT_CMD function to not be too chatty if it succeeds,
or even if it fails with INVALID_PARM (which just means that the handle
doesn't refer to an active commane).
End two weeks of on and off debugging. Fix the crash on the Nth
insertion of a CF card, for random values of N > 1. With these fixes,
I've been able to do 100 insert/remove of the cards w/o a crash with
lots of system activity going on that in the past would help trigger
the crash.
The problem:
FreeBSD creates dev_t's on the fly as they are needed and never
destroys them. These dev_t's point to a struct disk that is used for
housekeeping on the disk. When a device goes away, the struct disk
pointer becomes a dangling pointer. Sometimes when the device comes
back, the pointer will point to the new struct disk (in which case the
insertion will work). Other times it won't (especially if any length
of time has passed, since it is dependent on memory returned from
malloc).
The Fix:
There is one of these dev_t's that is always correct. The
device for the WHOLE_DISK_SLICE is always right. It gets set at
create_disk() time. So, the fix is to spend a little CPU time and
lookup the WHOLE_DISK_SLICE dev_t and use the si_disk from that in
preference to the one that's in the device asking to do the I/O. In
addition, we change the test of si_disk == NULL meaning that the dev
needed to inherit properties from the pdev to dev->si_disk !=
pdev->si_disk. This test is a little stronger than the previous test,
but can sometimes be fooled into not inheriting. However, the results
of this fooling are that the old values will be used, which will
generally always be the same as before. si_drv[12] are the only
values that are copied that might pose a problem. They tend to change
as the si_disk field would change, so it is a hole, but it is a small
hole.
One could correctly argue that one should replace much of this code
with something much much better. I would be on the pro side of that
argument.

TODO: 2nd arg type should be socklen_t for RFC2553 conformance,

o Introduce cap_{get,set}_{file,fd}() syscall wrappers, associated with
soon to be committed syscall stubs. These calls will be used to get
and set capability state associated with executables.
o When calling the syscall, use &cap instead of cap. Apparently this
error was introduced during the merge; fixing it corrects a (correct)
warning about types.
add getifaddrs(3) from bsdi. this is a magic function which lets you grab
interface addresses in a portable manner, without headache of SIOCGIFCONF
or sysctl. it is in bsdi/openbsd/netbsd already.
from kame tree (actually, mandatory for latest kame tree).
once built, 'kld_load snd_driver; kldunload snd_driver' will load all sound
drivers and unload all unattached ones. attached drivers do not yet support
unloading.

FreeBSD.org e-mail.
o Notice also that it's listed as "aud" not "audit" which will
probably change in the near future with updates to the auditing
implementation.

Replace the PQ_*CACHE options with a single PQ_CACHESIZE option that you

still supported for backwards compatibility.
Get userland visible flags added for snapshots to give a few days

Move the truncation code out of vn_open and into the open system call
after the acquisition of any advisory locks. This fix corrects a case
in which a process tries to open a file with a non-blocking exclusive
lock. Even if it fails to get the lock it would still truncate the
file even though its open failed. With this change, the truncation
is done only after the lock is successfully acquired.
If a buffer flush fails when trying to reclaim a vnode, it is too
late to save the vnode, so just toss any remaining unwritten buffers
rather than leaving them lying around to make trouble in the future.
Add in config_hook for catching when interrupts are safe- this allows
us to not the ints are ok and also to (re)ENABLE isp interrupts. Remove
all splcam()/splx() invocates and replace them with ISP_LOCK/ISP_UNLOCK
macros.
Add in isp_lock/isp_unlock inlines. Add in an islocked/intsok flag
to isp_osinfo substructure (all in prep for SMP). Define MBOX_WAIT_COMPLETE
and MBOX_NOTIFY_COMPLETE macros so that we can now (temp) use tsleep
to wait for mailbox completion. Requires us to guess whether we're
servicing an interrupt or not- will use intr_nesting_level.
Change delay loop in new isp_mboxcmd to the use of the new MBOX_WAIT_COMPLETE
macro. Change notification of completion of a mailbox command in isp_intr

This prevents the overwrite yes/no prompt from occuring in gzip.
(some PicoBSD disks use gzip and some use minigzip, so the gzip -f flag (force)
is not an option. minigzip has a different meaning for the -f flag.}
Make the two calls from kern/* into softupdates #ifdef SOFTUPDATES,
that is way cleaner than using the softupdates_stub stunt, which

Fix breakage introduced by bypassing update for additional 'mod'
functionality when nothing had actually changed; -d changes would
not set the 'something had changed flag'. Actually test for a

What the commit log for rev 1.16 neglected to mention was that the
