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.

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

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.

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.

MAC label on some packet header mbufs might not be set in mbufs
allocated using m_getcl(), resulting in a page fault.

vnode operations. This permits the rights of the user (typically root)
used to turn on accounting to be used when writing out accounting entries,
rather than the credentials of the process generating the accounting
record. This fixes accounting in a number of environments, including
file systems that offer revocation support, MAC environments, some
securelevel scenarios, and in some NFS environments.

the initproc credential from the proc0 credential. Otherwise, the
proc0 credential is used instead of initproc's credentil when authorizing
start_init() activities prior to initproc hitting userland for the
first time. This could result in the incorrect credential being used
to authorize mounting of the root file system, which could in turn cause
problems for NFS when used in combination with uid/gid ipfw rules, or
with MAC.
