update_plex_state:
  If any subdisk in the plex is initializing, set the plex to
  initializing state.  This gets rid of the ugly corrupt/degraded/up
  transitions which previously occurred.

logrq: save device major and minor numbers to compensate for lost
  dev_t.

launch_requests: Don't issue requests which are marked
  XFR_BAD_SUBDISK.  This may make things easier in bre().

bre:
  Rearrange.
  - Change some comments
  - Recognize holes in plex structure.  Formerly this could lead to
    incorrect write to the plex.  Return REQUEST_DEGRADED on a read
    request, but carry on to the bitter end on a write request, and
    mark the requests for the inaccessible subdisks with
    XFR_BAD_SUBDISK.
  - return REQUEST_EOF if the requested transfer goes beyond the end
    of the plex.  This is not an error, since other plexes may go
    further into the volume address space.

build_read_request:
  Handle REQUEST_DEGRADED returned from bre().

sdio:
  Lock buffer before issuing the requests.

2af0d14102 Remove code to accept partitions of type 'unused'. From now on, Vinum
will only accept partitions of type 'vinum'.

format_config: Use the new %q format option in kvprintf, thus getting
  rid of some of the filthiest code I've written in a long time.  Also
  remove the lltoa() function.

With-great-thanks-to:	peter

format_config: Accept the fact that a subdisk might not be attached to
  a plex, and save the config correctly.

vinum_scandisk: Scan all slices on a drive with a Microsoft partition
  table.  Only look at the compatibility slice if nothing was found in
  the Microsoft slices.

  This change removes a frequently employed method of shooting
  yourself in the foot: people would decide that the Vinum drives
  belonged on their own slice, and they wouldn't be able to start the
  subsystem after a reboot.  Documentation updates to follow.

0b90cf6a6e vinumopen: add code to open raw subdisks. This is now used to
initialize subdisks.  Probably the plex-related subdisk type will die
a death.

vinumconfig.c:

Accept (and ignore) kernel state information in userland config
files.  This saves a lot of error recovery and also makes it possible
to use the output of printconfig to create new configuration.

Remove checkdiskconfig().  It wasn't needed any more.

Start adding support for hot spare drives.  You can't put anything on
them (yet).

Change message formats from %lld to %qd.

get_empty_sd: Initialize size to -1.  Previously this was done in
config_subdisk, which is the wrong place.

start_config: set current drive, plex and volume to -1, thus stopping
  update configurations from taking their defaults from old configs.

d0cd160775 We don't end up checking for a return value of EFAULT from the copyinstr()
in the pathname translation procedure. This proves fatal, and can be
easily fixed. This or a similar change needs to be committed to svr4_util.h
and ibcs2_util.h. I will update ibcs2_util.h, if noone else thinks of a
better way to do this, in the same manner. I will leave svr4 to the
respective maintainer.

This closes the problem of the only crash I've been able to produce as
a user recently, except for (currently not-in-the-source tree) fd
table sharing fixes. Thanks goes to pho for his stress-testers.

c03366a55d Fix fd race conditions (during shared fd table usage.) Badfileops is
now used in f_ops in place of NULL, and modifications to the files
are more carefully ordered. f_ops should also be set to &badfileops
upon "close" of a file.

This does not fix other problems mentioned in this PR than the first
one.

fce0d9b321 Don't over-allocate and over-copy shorter NFSv2 filehandles and then
correct the pointers afterwards.

It's kinda bogus that we generate a 24 (?) byte filehandle (2 x int32
fsid and 16 byte VFS fhandle) and pad it out to 64 bytes for NFSv3 with
garbage.  The whole point of NFSv3's variable filehandle length was
to allow for shorter handles, both in memory and over the wire.  I plan
on taking a shot at fixing this shortly.

257891ab9f Perform an RX reset and TX reset in xl_reset() along with the master
reset command.

I observed some anomalous behavior while testing a 3c905C with a
Dell PowerEdge 4300/500 dual PIII 500Mhz system. The NIC would seem
to work correctly most of the time but would sometimes fail to receive
certain packets, in particular NFS create requests. I could mount
an NFS filesystem from the PowerEdge and do an ls on it, but trying
to do a "touch foo" would hang. Monitoring traffic from another host
revealed that the client was properly sending an NFS create request
but the server was not receiving it. It *did* receive it when I
ran the same test with an Intel fxp card.

I don't understand the exact mechanics of this strange behavior, but
resetting the receiver and transmitter seems to get rid of it. I used
to perform an RX and TX reset in xl_init(), but stopped doing it there
because on 3c905B and later cards this causes the autoneg session to
restart, which would lead to the NIC waiting a long time before exchanging
traffic after being brought up the first time. Apparently the receiver
and transmitter resets should be performed at least once when initializing
the card.

Hopefully this will cure problems that people have been having with the
3c905C -- this was the only strange behavior that I have observed with
the 3c905C so far which does not appear with the 3c905B or 3c905.

c790088cf6 Move the specification of EDGE/LEVEL triggered interrupts to
eisa_add_intr() which now takes an additional arguement (one of
EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE).

The flag RR_SHAREABLE has no effect when passed to
bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as
the eisa_alloc_resource() call (bus_alloc_resource method) now deals
with this flag directly, depending on the device ivars.

This change does nothing more than move all the 'shared = inb(foo + iobsse)'
nonesense to the device probe methods rather than the device attach.

Also, print out 'edge' or 'level' in the IRQ announcement message.

d848a791d1 Make ipfw's logging more dynamic. Now, log will use the default limit
_or_ you may specify "log logamount number" to set logging specifically
the rule.
   In addition, "ipfw resetlog" has been added, which will reset the
logging counters on any/all rule(s). ipfw resetlog does not affect
the packet/byte counters (as ipfw reset does), and is the only "set"
command that can be run at securelevel >= 3.
   This should address complaints about not being able to set logging
amounts, not being able to restart logging at a high securelevel,
and not being able to just reset logging without resetting all of the
counters in a rule.
