program logic or assumptions is deficient.

Also shuffle i386/drivers.conf so that the floppies don't overflow
anymore. Anybody with real/better usage statistics is welcome to
shuffle it differently.

label updates. Biba and MLS already supported this. This permits the
userland library to submit relative updates on MAC labels, rather
than submitting an entire label to replace the current label. This
also requires changes to the MAC modules, which are forthcoming.

o Remove the race between stat(2) & fopen(3) when creating
a unique file.
o Improve bound checking when generating a unique name from
a given pathname.
o Ignore REST marker on APPE. No RFC specifies this case,
but the idea of resuming APPE's implies this.
o By default, deny upload resumes and appends by anonymous users.
Previously these commands were translated to STOU silently,
which led to broken files on server without any notification
to the user.
o Add an option, -m, to allow anonymous users to modify
existing files (e.g., to resume uploads) if filesystem
permissions permit.

and _end symbol has less chances to clash with application defined
global symbols.
alpha, ia64 and sparc64 ports already use _end, i386 is now
consistent with them.

objects' reference counts. This function is called by the atexit
mechanism at program shutdown. I don't think the locking is necessary
here. It caused OpenOffice builds to hang more often than not.
Credit to Martin Blapp and Matt Dillon for helping to diagnose this
problem and for testing the fix.
appologize to those of you who may have been seeing crashes in
code that uses sendfile(2) or other types of external buffers
with mbufs.

VOP wrapper is called from within file systems so can result in odd
loopback effects when MAC enforcement is use with the active (as
opposed to saved) credential. These checks will be moved elsewhere.

Enjoy!
I'm not sure what happenned to the original setting of the P_CONTINUED
flag. it appears to have been lost in the paper shuffling...

currently cached data. It allows a number of nice things, like: removing
fallback code from single locale loading, remove memory leak when LC_CTYPE
data loaded again and again, efficient cache use, not only for
setlocale(locale1); setlocale(locale1), but for setlocale(locale1);
setlocale("C"); setlocale(locale1) too (i.e. data file loaded only once).
This is pretty much fixes any issue I can find:
- Watchdog timeouts were due to starting the TX DMA engine
before we had a packet ready for it. So the first packet
sent never got out only if we sent more then one packet
at a time did the others make it out and not blow up.
Of course reseting the chip then caused us not to transmit
the first packet again ie. catch-22. This required logic changes.
- Combine interrupts on TX packets being queued up.
- Don't keep running around the RX ring since we might get
out of sync so only go around once per receive
- Let the RX engine recover via the poll interface which is
similar to the TX interface. This way the chip wakes
up with no effort when we read enough packets.
- Do better hand-shaking on RX & TX packets so they don't
start of to soon.
- Force a duplex setting when the link comes up after
an ste_init or it will default to half-duplex and be
really slow. This only happens on subsequent ste_init.
The first one worked.
- Don't call stat_update for every overflow. We only monitor
the collisions so the tick interval is good enough for that.
Just read in the collision stats to minimize bus reads.
- Don't read the miibus every tick since it uses delays and
delays are not good for performance.
- Tie link events directly to the miibus code so the port
gets set correctly if someone changes the port settings.
- Reduce the extreme number of {R,T}FD's. They would consume
130K of kernel memory for each NIC.
- Set the TX_THRESH to wait for the DMA engine to complete
before running the TX FIFO. This hurts peak TX performance
but under bi-directional load the DMA engine can't keep up
with the FIFO. Testing shows that we end up in the case
anyways (a la dc(4) issues but worse since the RX engine hogs
everything).
- When stopping the card do a reset since the reset verifies the
card has stopped. Otherwise on heavy RX load the RX DMA engine
is still stuffing packets into memory. If that happens after
we free the DMA area memory bits get scribled in memory and
bad things happen.
This card still has seemingly unfixable issues under heavy RX load in
which the card takes over the PCI bus.
