Enhance the sequential access heuristic used to perform readahead in the
NFS server and reuse it for writes as well to allow writes to the backing
store to be clustered.
- Use a prime number for the size of the heuristic table (1017 is not
  prime).
- Move the logic to locate a heuristic entry from the table and compute
  the sequential count out of VOP_READ() and into a separate routine.
- Use the logic from sequential_heuristic() in vfs_vnops.c to update the
  seqcount when a sequential access is performed rather than just
  increasing seqcount by 1.  This lets the clustering count ramp up
  faster.
- Allow for some reordering of RPCs and if it is detected leave the current
  seqcount as-is rather than dropping back to a seqcount of 1.  Also,
  when out of order access is encountered, cut seqcount in half rather than
  dropping it all the way back to 1 to further aid with reordering.
- Fix the new NFS server to properly update the next offset after a
  successful VOP_READ() so that the readahead actually works.

Some of these changes came from an earlier patch by Bjorn Gronwall that was
forwarded to me by bde@.

At this time it is not thought that authoritative-only servers

Because it may be possible to trigger this bug even on networks

Tweak the r137233 fix to r136283 -- Code was making two send() attempts
vs. the comment documented "If we are working with a privileged socket,
then take only one attempt".  Make the code match.

Furthermore, critical privileged applications that [over] log a vast amount
can look like a DoS to this code.  Given it's unlikely the single reattempted
send() will succeeded, avoid usurping the scheduler in a library API for a
single non-critical facility in critical applications.

Fix OF_finddevice error return value in case of FDT.

According to the open firmware standard, finddevice call has to return
a phandle with value of -1 in case of error.

This commit is to:
- Fix the FDT implementation of this interface (ofw_fdt_finddevice) to
  return (phandle_t)-1 in case of error, instead of 0 as it does now.
- Fix up the callers of OF_finddevice() to compare the return value with
  -1 instead of 0 to check for errors.
- Since phandle_t is unsigned, the return value of OF_finddevice should
  be checked with '== -1' rather than '<= 0' or '> 0', fix up these cases
  as well.

Post r223774, the NFSv4 client no longer has multiple instances
of the same lock_owner4 string. As such, the handling of cleanup
of lock_owners could be simplified. This simplification permitted
the client to do a ReleaseLockOwner operation when the process that
the lock_owner4 string represents, has exited. This permits the
server to release any storage related to the lock_owner4 string
before the associated open is closed. Without this change, it
is possible to exhaust a server's storage when a long running
process opens a file and then many child processes do locking
on the file, because the open doesn't get closed. A similar patch
was applied to the Linux NFSv4 client recently so that it wouldn't
exhaust a server's storage.

Allow the i2c node requirements to be slightly relaxed.

These realtek switch PHYs speak a variant of i2c with some slightly
modified handling.

From the submitter, slightly modified now that some further digging
has been done:

  The I2C framework makes a assumption that the read/not-write bit of the first
  byte (the address) indicates whether reads or writes are to follow.

  The RTL8366 family uses the bus: after sending the address+read/not-write byte,
  two register address bytes are sent, then the 16-bit register value is sent
  or received.  While the register write access can be performed as a 4-byte
  write, the read access requires the read bit to be set, but the first two bytes
  for the register address then need to be transmitted.

This patch maintains the i2c protocol behaviour but allows it to be relaxed
(for these kinds of switch PHYs, and whatever else Realtek may do with this
almost-but-not-quite i2c bus) - by setting the "strict" hint to 0.
The "strict" hint defaults to 1.

Support domain-search in dhclient(8)

The "domain-search" option (option 119) allows a DHCP server to publish
a list of implicit domain suffixes used during name lookup. This option
is described in RFC 3397.

For instance, if the domain-search option says:
    ".example.org .example.com"
and one wants to resolve "foobar", the resolver will try:
    1. "foobar.example.org"
    2. "foobar.example.com"

The file /etc/resolv.conf is updated with a "search" directive if the
DHCP server provides "domain-search".

A regression test suite is included in this patch under
tools/regression/sbin/dhclient.

This patch adds a sysctl to the NFSv4 server which optionally disables the
check for a UTF-8 compliant file name. Enabling this sysctl results in
an NFSv4 server that is non-RFC3530 compliant, therefore it is not enabled
by default. However, enabling this sysctl results in NFSv3 compatible
behaviour and fixes the problem reported by "dan at sunsaturn.com"
to freebsd-current@ on Nov. 14, 2011 under the subject "NFSV4 readlink_stat".

  Make a change to the implementation of the direct map to improve
  performance on processors that support 1 GB pages.  Specifically, if the
  end of physical memory is not aligned to a 1 GB page boundary, then map
  the residual physical memory with multiple 2 MB page mappings rather than
  a single 1 GB page mapping.  When a 1 GB page mapping is used for this
  residual memory, access to the memory is slower than when multiple 2 MB
  page mappings are used.  (I suspect that the reason for this slowdown is
  that the TLB is actually being loaded with 4 KB page mappings for the
  residual memory.)

1. Fix the handling of link reset while in netmap more.
   A link reset now is completely transparent for the netmap client:
   even if the NIC resets its own ring (e.g. restarting from 0),
   the client will not see any change in the current rx/tx positions,
   because the driver will keep track of the offset between the two.

2. make the device-specific code more uniform across different drivers
   There were some inconsistencies in the implementation of the netmap
   support routines, now drivers have been aligned to a common
   code structure.

3. import netmap support for ixgbe . This is implemented as a very
   small patch for ixgbe.c (233 lines, 11 chunks, mostly comments:
   in total the patch has only 54 lines of new code) , as most of
   the code is in an external file sys/dev/netmap/ixgbe_netmap.h ,
   following some initial comments from Jack Vogel about making
   changes less intrusive.
   (Note, i have emailed Jack multiple times asking if he had
   comments on this structure of the code; i got no reply so
   i assume he is fine with it).

Support for other drivers (em, lem, re, igb) will come later.

"ixgbe" is now the reference driver for netmap support. Both the
external file (sys/dev/netmap/ixgbe_netmap.h) and the device-specific
patches (in sys/dev/ixgbe/ixgbe.c) are heavily commented and should
serve as a reference for other device drivers.

Tested on i386 and amd64 with the pkt-gen program in tools/tools/netmap,
the sender does 14.88 Mpps at 1050 Mhz and 14.2 Mpps at 900 MHz
on an i7-860 with 4 cores and 82599 card. Haven't tried yet more
aggressive optimizations such as adding 'prefetch' instructions
in the time-critical parts of the code.

add netmap support for "em", "lem", "igb" and "re".

On my hardware, "em" in netmap mode does about 1.388 Mpps
on one card (on an Asus motherboard), and 1.1 Mpps on another
card (PCIe bus). Both seem to be NIC-limited, because
i have the same rate even with the CPU running at 150 MHz.

On the "re" driver the tx throughput is around 420-450 Kpps
on various (8111C and the like) chipsets. On the Rx side
performance seems much better, and i can receive the full
load generated by the "em" cards.

"igb" is untested as i don't have the hardware.

Introduce vm_reserv_alloc_contig() and teach vm_page_alloc_contig() how to
use superpage reservations.  So, for the first time, kernel virtual memory
that is allocated by contigmalloc(), kmem_alloc_attr(), and
kmem_alloc_contig() can be promoted to superpages.  In fact, even a series
of small contigmalloc() allocations may collectively result in a promoted
superpage.

Eliminate some duplication of code in vm_reserv_alloc_page().

Change the type of vm_reserv_reclaim_contig()'s first parameter in order
that it be consistent with other vm_*_contig() functions.

Protect kern.proc.auxv and kern.proc.ps_strings sysctls with p_candebug().

Citing jilles:

If we are ever going to do ASLR, the AUXV information tells an attacker
where the stack, executable and RTLD are located, which defeats much of
the point of randomizing the addresses in the first place.

Given that the AUXV information seems to be used by debuggers only anyway,
I think it would be good to move it to p_candebug() now.

The full virtual memory maps (KERN_PROC_VMMAP, procstat -v) are already
under p_candebug().

Most users of pipe(2) do not call fstat(2) on the returned pipe descriptors.
Optimize for the case, by lazily allocating the pipe inode number at the
fstat(2) time. If alloc_unr(9) returns failure, do not fail fstat(2), since
uses of inode numbers are even rare then fstat(2), but provide zero inode
forever. Note that alloc_unr() failure is unlikely due to total number
of pipes in the system limited by the number of file descriptors.

Implement quick_exit() / at_quick_exit() from C++11 / C1x.  Also add a
__noreturn macro and modify the other exiting functions to use it.

The __noreturn macro, unlike __dead2, must be used BEFORE the function.
This is in line with the C and C++ specifications that place _Noreturn (c1x)
and [[noreturn]] (C++11) in front of the functions.  As with __dead2, this
macro falls back to using the GCC attribute.

Unfortunately, clang currently sets the same value for the C version macro
in C99 and C1x modes, so these functions are hidden by default.  At some
point before 10.0, I need to go through the headers and clean up the C1x /
C++11 visibility.

Overhaul bus_dma(9) usage in et(4) and clean up TX/RX path.  This
change should make et(4) work on any architectures.
 o Remove m_getl inline function and replace it with stanard mbuf
   interfaces.  Previous code tried to minimize code duplication
   but this came from incorrect use of common DMA tag.
   Driver may be still use a common RX allocation handler with
   additional structure changes but I don't see much point to do
   that it would make it hard to understand the code.
 o Remove DragonflyBSD specific constant EVL_ENCAPLEN, use
   ETHER_VLAN_ENCAP_LEN instead.
 o Add bunch of new RX status definition.  It seems controller
   supports RX checksum offloading but I was not able to make the
   feature work yet.  Currently driver checks whether recevied
   frame is good one or not.
 o Avoid a typedef ending in '_t' as style(9) says.
 o Controller has no restriction on DMA address space, so there
   is no reason to limit the DMA address to 32bit.  Descriptor
   rings,  status blocks and TX/RX buffers now use full 64bit DMA
   addressing.
 o Allocate DMA memory shared between host and controller as
   coherent.
 o Create 3 separate DMA tags to be used as TX, mini RX ring and
   stanard RX ring.  Previously it created a single DMA tag and it
   was used to all three rings.
 o et(4) does not support jumbo frame at this moment and I still
   don't quite understand how jumbo frame works on this controller
   so use two RX rings to handle small sized frame and normal sized
   frame respectively.  The mini RX ring will be used to receive
   frames that are less than or equal to 127 bytes.  The second RX
   ring is used to receive frames that are not handled by the first
   RX ring.
   If jumbo frame support is implemented, driver may have to choose
   better RX scheme by letting the second RX ring handle jumbo
   frames.  This scheme will mimic Broadcom's efficient jumbo frame
   handling feature.  However RAM buffer size(16KB) of the
   controller is too small to hold 2 jumbo frames, if 9KB
   jumbo frame is used, I'm not sure how good performance would it
   have.
 o In et_rxeof(), make sure to check whether controller received
   good frame or not.  Passing corrupted frame to upper layer is
   bad idea.
 o If driver receives a bad frame or driver fails to allocate RX
   buffer due to resource shortage condition, reuse previously
   loaded DMA map for RX buffer instead of unloading/loading RX
   buffer again.
 o et_init_tx_ring() never fails so change return type to void.
 o In watchdog handler, show TX DMA write back status of errored
   frame which could be used as a clue to debug watchdog timeout.
 o Add missing bus_dmamap_sync() in various places such that et(4)
   should work with bounce buffers(e.g. PAE).
 o TX side bus_dmamap_load_mbuf_sg(9) support.
 o RX side bus_dmamap_load_mbuf_sg(9) support.
 o Controller has no DMA alignment limit in RX buffer so use
   m_adj(9) in RX buffer allocation to make IP header align on 2
   bytes boundary.  Otherwise it would trigger unaligned access
   error in upper layer on strict alignment architectures.
   One of down side of controller is it provides limited set of RX
   buffer length like most Intel controllers.  This is not problem
   at this moment because driver does not support jumbo frame yet
   but it may require alignment fixup code to support jumbo frame
   on strict alignment architectures.
 o In et_txeof(), don't zero TX descriptors for transmitted frames.
   TX descriptors don't need write access after transmission.
   Driver sets IFF_DRV_OACTIVE when the number of available TX
   descriptors are less than or equal to ET_NSEG_SPARE.  Make sure
   to clear IFF_DRV_OACTIVE only when the number of available TX
   descriptor is greater than ET_NSEG_SPARE.

Controller does not require TX start command for every frame.  So
send a single TX command after setting up all TX frames.  This
removes unnecessary register accesses and bus_dmamap_sync(9) calls.
et(4) uses TX interrupt moderation so it's possible to have TX
buffers that were already transmitted but waiting for TX completion
interrupt.  If the number of available TX descriptor is less then
1/3 of total TX descriptor, try reclaiming first to get enough free
TX descriptors before setting up TX descriptors.
After r228325, et_txeof() no longer tries to send frames after
reclaiming TX buffers.  That change was made to give more chance
to transmit frames in main interrupt handler since we can still
send frames in interrupt handler with RX interrupt.  So right
before exiting interrupt hander, after enabling interrupt, try to
send more frames.  This gives slightly better performance numbers.

While I'm here reduce number of spare TX descriptors from 8 to 4.
Controller does not require reserved TX descriptors, it was just to
reduce TX overhead.  After r228325, driver has much lower TX
overhead so it does not make sense to reserve 8 TX descriptors.

Remove et_enable_intrs(), et_disable_intrs() functions and
manipulation of interrupt register access is done through
CSR_WRITE_4 macro.  Also add disabling interrupt into et_reset()
because we want interrupt disabled state after controller reset.
While I'm here slightly change interrupt handler to be more
readable one.

Make it possible to use the debug versions of std::map and std::multimap
with clang, by removing two unneeded using declarations.  Otherwise, you
would get errors similar to:

/usr/include/c++/4.2/debug/map.h:77:20: error: dependent using declaration resolved to type without 'typename'
      using _Base::value_compare;
                   ^

N.B.: Take care when you actually use the debug versions of any
libstdc++ header.  They are more likely to contain problems, because
they are exercised far less often, and since the standard library
complexity guarantees don't always apply anymore, compile times can
drastically increase.

As per das@'s suggestion, s/__noreturn/_Noreturn/, since the latter is an
identifier reserved for the implementation in C99 and earlier so there is
no sensible reason for introducing yet another reserved identifier when we
could just use the one C1x uses.

Rework link state tracking and TX/RX MAC configuration.
 o Do not report link status if driver is not running.
 o TX/RX MAC configuration should be done with resolved speed,
   duplex and flow control after establishing a link so it can't
   be done in driver initialization routine.
   Move the configuration to miibus_statchg callback which will be
   called whenever any link state change is detected.
   At this moment, flow-control is not enabled yet mainly because
   I was not able to set correct flow control parameters to
   generate TX pause frames.
 o Now TX/RX MAC is enabled only when a valid link is detected.
   Rearragnge hardware initialization routine a bit to leave
   enabling MAC to miibus_statchg callback.  In order to that,
   TX/RX DMA engine is enabled in et_init_locked().
 o Introduce ET_FLAG_LINK flag to track current link state.
 o Introduce ET_FLAG_FASTETHER flag to mark whether controller is
   fast ethernet.  This flag is checked in miibus_statchg callback
   to know whether PHY established a valid link.
 o In et_stop(), TX/RX MAC is explicitly disabled instead of
   relying on et_reset().  And move et_reset() from et_stop() to
   controller initialization.  Controler reset is not required here
   and it would also clear critial registers(i.e station address,
   RX filter configuration, WOL etc) that are required to make WOL
   work.
 o Switching to current media is done in et_init_locked() after
   setting IFF_DRV_RUNNING flag.  This should ensure reliable
   auto-negotiation/manual link establishment.
 o In et_start_locked(), check whether driver got a valid link
   before trying to send frames.
 o Remove checking a link in et_tick() as this is done by
   miibus_statchg callback.
