in the build still due to some #undef's in svr4.h, but if you hack around
that and add some missing entries to syscalls.master, then this file will
now compile.  The changes involved proc -> thread, using FreeBSD syscall

cf15cbb1b6 - Add two new system calls: preadv() and pwritev() which are like readv()
and writev() except that they take an additional offset argument and do
  not change the current file position.  In SAT speak:
  preadv:readv::pread:read and pwritev:writev::pwrite:write.
- Try to reduce code duplication some by merging most of the old
  kern_foov() and dofilefoo() functions into new dofilefoo() functions
  that are called by kern_foov() and kern_pfoov().  The non-v functions
  now all generate a simple uio on the stack from the passed in arguments
  and then call kern_foov().  For example, read() now just builds a uio and
  calls kern_readv() and pwrite() just builds a uio and calls kern_pwritev().

23f56c61a9 - Previously when broadcasting to N number of interfaces we would run pfil
hooks for each outgoing interface but also run pfil hooks _N times_ on the
  bridge interface. This is changed so pfil hooks are run once for the bridge
  interface (bridge0) and then only on the outgoing interfaces in the broadcast
  loop.

- Simplify bridge_enqueue() by moving bridge_pfil() to the callers.

- Check (inet6_pfil_hook.ph_busy_count >= 0), it may be possible to have a
  packet filter hooked for only ipv6 but we were only checking if ipv4 hooks
  were busy.

- Minor optimisation for null mbuf check after bridge_pfil(), move it into the
  if-block as it couldnt possibly be null outside.

fcbdfd0eb4 In the splnet times, netgraph was functional and synchronous. Nowadays,
an item may be queued and processed later. While this is OK for mbufs,
this is a problem for control messages.

In the framework:
- Add optional callback function pointer to an item. When item gets
  applied the callback is executed from ng_apply_item().
- Add new flag NG_PROGRESS. If this flag is supplied, then return
  EINPROGRESS instead of 0 in case if item failed to deliver
  synchronously and was queued.
- Honor NG_PROGRESS in ng_snd_item().

In ng_socket:
- When userland sends control message add callback to the item.
- If ng_snd_item() returns EINPROGRESS, then sleep.

This change fixes possible races in ngctl(8) scripts.

alignment such as sparc64, ia64 and ppc.

This uses the code block from if_bridge and the newly added macro

This /might/ be a temporary messure before all NIC drivers are educated
to align the header themself.

a4baf63c50 Switch Unicode charset name from "ISO-10646-UCS-2" to "UTF-16BE".
Using ISO-10646-UCS-2 will cause a problem when we use our own
iconv functions in the future, or port iconv other than GNU
libiconv.

Each vendors treat "UCS-2" as follows, and endian issue is
vendor specific:

 - Solaris 8 iconv
  Little Endian with BOM

 - HP-UX iconv
  Big Endian

 - NetBSD/i386 1.6 iconv
  Little Endian

 - GNU libiconv
  Big Endian

 - glibc(RedHat AS 2.1 x86) iconv
  Little Endian

 - IANA
  Name: ISO-10646-UCS-2
  MIBenum: 1000
  Source: the 2-octet Basic Multilingual Plane, aka Unicode
          this needs to specify network byte order: the standard
          does not specify (it is a 16-bit integer space)
  Alias: csUnicode

 - MSDN
  Little Endian
  http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemtextencodingclassgetencodingtopic2.asp

Now using UTF-16BE is harmless, because
- same as UCS-2 with 2 byte range (U+0000 - U+FFFF)
- kernel code of each file systems(cd9660, msdosfs, ntfs) believes
  Unicode is a 2 byte character at this time.
- UDF has only 2 byte range of Unicode filenames.
- It's defined at RFC2781.

So I believe it's time to change before starting new RELENG_6. :)

9e64e57e54 Implement functions calls from within DDB on ia64. On ia64 a function
pointer doesn't point to the first instruction of that function, but
rather to a descriptor. The descriptor has the address of the first
instruction, as well as the value of the global pointer. The symbol
table doesn't know anything about descriptors, so if you lookup the
name of a function you get the address of the first instruction. The
cast from the address, which is the result of the symbol lookup, to a
function pointer as is done in db_fncall is therefore invalid.
Abstract this detail behind the DB_CALL macro. By default DB_CALL is
defined as db_fncall_generic, which yields the old behaviour. On ia64
the macro is defined as db_fncall_ia64, in which a descriptor is
constructed to yield a valid function pointer.

While here, introduce DB_MAXARGS. DB_MAXARGS replaces the existing
(local) MAXARGS. The DB_MAXARGS macro can be defined by platforms to
create a convenient maximum. By default this will be the legacy 10.
On ia64 we define this macro to be 8, for 8 is the maximum number of
arguments that can be passed in registers. This avoids having to
implement spilling of arguments on the memory stack.

d7e928629d Check the alignment of the IP header before passing the packet up to the
packet filter. This would cause a panic on architectures that require strict
alignment such as sparc64 (tier1) and ia64/ppc (tier2).

This adds two new macros that check the alignment, these are compile time
dependent on __NO_STRICT_ALIGNMENT which is set for i386 and amd64 where
alignment isn't need so the cost is avoided.

 IP_HDR_ALIGNED_P()
 IP6_HDR_ALIGNED_P()

Move bridge_ip_checkbasic()/bridge_ip6_checkbasic() up so that the alignment
is checked for ipfw and dummynet too.

019106f6e5 Remove the CPU_ENABLE_SSE option from the i386 and pc98 architectures,
as they are already default for I686_CPU for almost 3 years, and
CPU_DISABLE_SSE always disables it.  On the other hand, CPU_ENABLE_SSE
does not work for I486_CPU and I586_CPU.

This commit has:
	- Removed the option from conf/options.*
	- Removed the option and comments from MD NOTES files
	- Simplified the CPU_ENABLE_SSE ifdef's so they don't
	  deal with CPU_ENABLE_SSE from kernel configuration. (*)

For most users, this commit should be largely no-op.  If you used to
place CPU_ENABLE_SSE into your kernel configuration for some reason,
it is time to remove it.

(*) The ifdef's of CPU_ENABLE_SSE are not removed at this point, since
    we need to change it to !defined(CPU_DISABLE_SSE) && defined(I686_CPU),
    not just !defined(CPU_DISABLE_SSE), if we really want to do so.

696ddfbe75 Fix a buglet that was present in the ia64 code and that got inherited
by amd64 and i386: For buffered writes we collect data and write it
out a ${DEV_BSIZE}-sized block at a time. The fragsz variable is used
to keep track of how much data we have collected in the buffer so far
and it's reset to zero immediately after writing a block to the dump
device.
When the last, possibly partially filled buffer is flushed, we didn't
reset fragsz to 0 and as such would stop reflecting reality. Since we
currently only need to do buffered writes once, this isn't a problem.
However, when kernel dumps are made by hand (say by callling doadump
from within DDB), the improperly cleared state from the first call to
dumpsys causes the next call to dumpsys to create an invalid code file.
This change resets fragsz after flushing the partially filled buffer so
that it fixes the two problems at once.

- Introducing the possibility of using locks different than mutexes
for the knlist locking. In order to do this, we add three arguments to

check if the lock is owned. If these arguments are NULL, we assume
mtx_lock, mtx_unlock and mtx_owned, respectively.

- Using the vnode lock for the knlist locking, when doing kqueue operations
on a vnode. This way, we don't have to lock the vnode while holding a

859ea2829a Minor cleanup of ep driver and pccard attachment:
o Grab the MAC address out of the CIS if the card has the special
  3Com 0x88 tuple.  Most 3Com cards don't have this tuple, but we
  prefer it to the eeprom since it only appears to be present when
  the eeprom doesn't have the info.  So far, I've only observed this
  on my 3C362 and 3C362B cards, but the NetBSD driver implies that
  the 3C362C also has this tuple, and that some 3C574 cards do too (none
  of mine do).  ep_pccard_mac was written after looking at the NetBSD
  code.
o Store the enet addr in the softc for this device, so we can use the
  overridden MAC to set the station address.
o Create a routine to set the station address and use it where we need it.
o setup the cmd shitfs and such before we call ep_alloc(), and remove
  setting up the cmd shift value there.  It initializes to 0, and those
  attachments that need to frob it do so before calling ep_alloc.
o Remove some obsolete comments
o No longer a need to export ep_get_macaddr, so make it static
o ep_alloc already grabs the EEPROM id, so we don't need to grab it again
  in ep_pccard_attach.
o eliminate unit, it isn't needed, fix some printfs to be device_printf
  instead.

64e8045b62 Add a much-requested feature: The ability for pccard attachments to
scan the CIS for interesting tuples.  95% of what can be obtained from
the CIS is harvested by the pccard layer and presented to the user in
standard function calls.  However, there are special needs at times
where the standard stuff doesn't suffice.  This is for those special
cases.

CARD_SCAN_CIS(device_get_parent(dev), function, argp)
	scans the CIS of the card, passing each tuple to function with
	the tuple and argp as its arguments.  Returning 0 continues the scan,
	while returning 1 terminates the scan.  The value of the last
	invocation of function is returned from this function.

int (*pccard_scan_t)(struct pccard_tuple *tuple, void *argp)
	function called for each tuple.  Elements of the CIS tuple can be
	read with pccard_tuple_read_{1,2,3,4,n}().  You are reading
	the actual tuple memory each time, in case your card has
	registers in the CIS.

# I suppose these things should be documented in pccard(4) or something like
# that.

# I plan on unifying cardbus CIS support in a similar way.

921b3c5ee4 Jumbo-commit to enhance 32 bit application support on 64 bit kernels.
This is good enough to be able to run a RELENG_4 gdb binary against
a RELENG_4 application, along with various other tools (eg: 4.x gcore).
We use this at work.

ia32_reg.[ch]: handle the 32 bit register file format, used by ptrace,
	procfs and core dumps.
procfs_*regs.c: vary the format of proc/XXX/*regs depending on the client
	and target application.
procfs_map.c: Don't print a 64 bit value to 32 bit consumers, or their
	sscanf fails.  They expect an unsigned long.
imgact_elf.c: produce a valid 32 bit coredump for 32 bit apps.
sys_process.c: handle 32 bit consumers debugging 32 bit targets.  Note
	that 64 bit consumers can still debug 32 bit targets.

IA64 has got stubs for ia32_reg.c.

Known limitations: a 5.x/6.x gdb uses get/setcontext(), which isn't
implemented in the 32/64 wrapper yet.  We also make a tiny patch to
gdb pacify it over conflicting formats of ld-elf.so.1.

14ff9254d8 Begin promoting the AMD-originated feature flags to first class flags, now
that newer Intel cpu hardware implements them too.  This includes things
like the NX (pte no-execute) flag for execute protection.  We'll need to
reference this for implementing no-exec in pmap.c at some point.

Some feature flags are duplicated in both the Intel-orignated bits and
the AMD bits.  Suppress the the duplicates correctly - the old code
assumed they were a 1:1 mapping which is not correct.  We can't just mask
off the bits present in cpu_feature.

Converge with amd64 where this originated from.

Intel cpu's that implement any AMD features will report them in dmesg now.

procfs.  Certain 3rd party drivers with binary userland components also
have this too.

49bfde6bf0 Switch AMD64 and i386 platforms to using ELF as their kernel crash
dump format.  The key reason to do this is so that we can dump sparse
address space.  For example, we need to be able to skip the PCI hole
just below the 4GB boundary.  Trying to destructively dump MMIO device
registers is Really Bad(TM).  The frequent result of trying to do a
crash dump on a machine with 4GB or more ram was ugly (lockup or reboot).

This code has been taken directly from the IA64 dump_machdep.c code,
with just a few (mostly minor) mods.

Introduce a dump_avail[] array in the machdep.c code so that we have a
source of truth for what memory is present in a machine that needs to be
dumped.  We can't use phys_avail[] because all sorts of things slice
memory out of it that we really need to dump.  eg: the vm page array
and the dmesg buffer.  dump_avail[] is pretty much an unmolested version
of phys_avail[].  It does have Maxmem correction.

Bump the i386 and amd64 dump format to version 2, but nothing actually
uses this.  amd64 was actually using the i386 dump version number.

libkvm support to follow.

b3e8712f74 Handle B-unit break instructions. The break.b is unique in that the
immediate is not saved by the architecture. Any of the break.{mifx}
instructions have their immediate saved in cr.iim on interruption.
Consequently, when we handle the break interrupt, we end up with a
break value of 0 when it was a break.b. The immediate is important
because it distinguishes between different uses of the break and
which are defined by the runtime specification.
The bottomline is that when the GNU debugger replaces a B-unit
instruction with a break instruction in the inferior, we would not
send the process a SIGTRAP when we encounter it, because the value
is not one we recognize as a debugger breakpoint.

This change adds logic to decode the bundle in which the break
instruction lives whenever the break value is 0. The assumption
being that it's a break.b and we fetch the immediate directly out
of the instruction. If the break instruction was not a break.b,
but any of break.{mifx} with an immediate of 0, we would be doing
unnecessary work. But since a break 0 is invalid, this is not a
problem and it will still result in a SIGILL being sent to the
process.

c6e57e046e Disable checksum processing in LibAlias, when it works as a
kernel module. LibAlias is not aware about checksum offloading,
so the caller should provide checksum calculation. (The only
current consumer is ng_nat(4)). When TCP packet internals has
been changed and it requires checksum recalculation, a cookie
is set in th_x2 field of TCP packet, to inform caller that it
needs to recalculate checksum. This ugly hack would be removed
when LibAlias is made more kernel friendly.

Incremental checksum updates are left as is, since they don't
conflict with offloading.

f1f0123e88 Fix some long standing bugs in writing to the BPF device attached to
a DLT_NULL interface. In particular:

        1) Consistently use type u_int32_t for the header of a
           DLT_NULL device - it continues to represent the address
           family as always.
        2) In the DLT_NULL case get bpf_movein to store the u_int32_t
           in a sockaddr rather than in the mbuf, to be consistent
           with all the DLT types.
        3) Consequently fix a bug in bpf_movein/bpfwrite which
           only permitted packets up to 4 bytes less than the MTU
           to be written.
        4) Fix all DLT_NULL devices to have the code required to
           allow writing to their bpf devices.
        5) Move the code to allow writing to if_lo from if_simloop
           to looutput, because it only applies to DLT_NULL devices
           but was being applied to other devices that use if_simloop
           possibly incorrectly.

1d30c90da0 Fix fdcheckstd to pass the file descriptor along through vn_open. When
opening a device, devfs_open needs the file descriptor to install its
own fileops. Failing to pass the file descriptor causes the vnode to
be returned with the regular vnops, which will cause a panic on the
first read or write because devfs_specops is not meant to support
those operations.

This bug caused a panic after exec'ing any set[ug]id program with
fds 0..2 closed (i.e., if any action had to be taken by fdcheckstd, we
would panic if the exec'd program ever tried to use any of those
descriptors).

23c82e526b Backout the change I made before 5.4-R since I wasn't aware that it was only
a problem with one particular switch module.  Create a kernel option
BGE_FAKE_AUTONEG that restores the 5.4 behavior, which should make the DNLK
switch module work. IBM/Intel blades with Intel or AD switch modules should
work without patching or kernel options with this commit.

Hardware for testing provided by several folks, including
Danny Braniss <danny@cs.huji.ac.il>, Achim Patzner <ap@bnc.net>,

0a8b4194dc Correct the amount of data to allocate in these local copies of
exec_copyin_strings() to catch up to rev 1.266 of kern_exec.c.  This fixes
panics on amd64 with compat binaries since exec_free_args() was freeing
more memory than these functions were allocating and the mismatch could
cause memory to be freed out from under other concurrent execs.

   RELENG_4 doesn't panic but spews following errors:

d1b7fc96b0 Add back missing copyright and license statement. This is identical
to the statement in ip_mroute.h, as well as being the same as what
OpenBSD has done with this file.  It matches the copyright in NetBSD's
1.1 through 1.14 versions of the file as well, which they subsequently
added back.

It appears to have been lost in the 4.4-lite1 import for FreeBSD 2.0,
but where and why I've not investigated further.  OpenBSD had the same
problem.  NetBSD had a copyright notice until Multicast 3.5 was
integrated verbatim back in 1995.  This appears to be the version that
made it into 4.4-lite1.
