57feb6fb43 Fix integer truncation bug in malloc(9)
A couple of internal functions used by malloc(9) and uma truncated
a size_t down to an int.  This could cause any number of issues
(e.g. indefinite sleeps, memory corruption) if any kernel
subsystem tried to allocate 2GB or more through malloc.  zfs would
attempt such an allocation when run on a system with 2TB or more
of RAM.

Note to self: When this is MFCed, sparc64 needs the same fix.

67c45e2f58 pf: Deal with runt packets
On Ethernet packets have a minimal length, so very short packets get padding
appended to them. This padding is not stripped off in ip6_input() (due to
support for IPv6 Jumbograms, RFC2675).
That means PF needs to be careful when reassembling fragmented packets to not
include the padding in the reassembled packet.

While here also remove the 'Magic from ip_input.' bits. Splitting up and
re-joining an mbuf chain here doesn't make any sense.

When forwarding fragmented IPv6 packets and filtering with PF we
reassemble and refragment. That means we generate new fragment headers
and a new fragment ID.

We already save the fragment IDs so we can do the reassembly so it's
straightforward to apply the incoming fragment ID on the refragmented
packets.

b7c417708f Refine r280308. Do not completely disable timestamping of devfs nodes
on reads or writes, the time marks are used to display idle time by
w(1) [1].  Instead, use vfs.devfs.dotimes as the selector of default
precision vs. using time_second.  The later gives seconds precision,
which is good enough for the purpose.

Note that timestamp updates are unlocked and the updates itself, as
well as the check in devfs_timestamp, are non-atomic.

2fdd06cb68 Start the process of migrating the ANI statistics out of the HALs and into
the top-level HAL.

The athstats program is blindly using a copy of the ar5212 ANI stats structure
to pull out ANI statistics/state and this is problematic for the AR9300
HAL.

So:

* Define HAL_ANI_STATS and HAL_ANI_STATE
* Use HAL_ANI_STATS inside the AR5212 HAL

This commit doesn't (yet) convert the ar5212AniState -> HAL_ANI_STATE when
exporting it to userland; that'll come in the next commit.

Summary:
Add "GELI Passphrase:" prompt to boot loader.

A new loader.conf(5) option of geom_eli_passphrase_prompt="YES" will now
allow you to enter your geli(8) root-mount credentials prior to invoking
the kernel.

Test Plan:
Drop a head copy of check-password.4th into /boot and then apply the patch
(only the patch to /boot/check-password.4th is required; no other changes are
required but you do have to have a HEAD copy of check-password.4th to
apply the patch).

NB: The rest of your /boot files can be up to 2 years old but no older.
NB: The test won't work unless your kernel has the following change

https://svnweb.freebsd.org/base?view=revision&revision=273489

Now, put into /boot/loader.conf:

geom_eli_passphrase_prompt="YES"

and reboot.

You should be prompted for a GELI passphrase before the menu (if enabled),
just after loading loader.conf(5).

NB: It doesn't matter if you're using GELI or not. However if you are using
GELI and a sufficiently new enough release (has SVN r273489) and you entered
the proper passphrase to mount your GELI encrypted root device(s), you should
notice that the boot process did not stop (you went from loader all the way to login).

299467e040 Fix overflow bugs in and remove obsolete limit from kernel RPC
implementation.

The kernel RPC code, which is responsible for the low-level scheduling
of incoming NFS requests, contains a throttling mechanism that
prevents too much kernel memory from being tied up by NFS requests
that are being serviced.  When the throttle is engaged, the RPC layer
stops servicing incoming NFS sockets, resulting ultimately in
backpressure on the clients (if they're using TCP).  However, this is
a very heavy-handed mechanism as it prevents all clients from making
any requests, regardless of how heavy or light they are.  (Thus, when
engaged, the throttle often prevents clients from even mounting the
filesystem.)  The throttle mechanism applies specifically to requests
that have been received by the RPC layer (from a TCP or UDP socket)
and are queued waiting to be serviced by one of the nfsd threads; it
does not limit the amount of backlog in the socket buffers.

The original implementation limited the total bytes of queued requests
to the minimum of a quarter of (nmbclusters * MCLBYTES) and 45 MiB.
The former limit seems reasonable, since requests queued in the socket
buffers and replies being constructed to the requests in progress will
all require some amount of network memory, but the 45 MiB limit is
plainly ridiculous for modern memory sizes: when running 256 service
threads on a busy server, 45 MiB would result in just a single
maximum-sized NFS3PROC_WRITE queued per thread before throttling.

Removing this limit exposed integer-overflow bugs in the original
computation, and related bugs in the routines that actually account
for the amount of traffic enqueued for service threads.  The old
implementation also attempted to reduce accounting overhead by
batching updates until each queue is fully drained, but this is prone
to livelock, resulting in repeated accumulate-throttle-drain cycles on
a busy server.  Various data types are changed to long or unsigned
long; explicit 64-bit types are not used due to the unavailability of
64-bit atomics on many 32-bit platforms, but those platforms also
cannot support nmbclusters large enough to cause overflow.

This code (in a 10.1 kernel) is presently running on production NFS
servers at CSAIL.

Summary of this revision:
* Removes 45 MiB limit on requests queued for nfsd service threads
* Fixes integer-overflow and signedness bugs
* Avoids unnecessary throttling by not deferring accounting for
  completed requests
