Get rid of an old and terrible hack.  Local stream sockets enqueue packets
directly on the peer's sockbuf, rather then the sender's sockbuf.  That
part of the code is fine, but in order to prevent the sender from queueing
infinite mbufs (because its sockbuf appears to be empty when you do that)
the code dynamically messed around with the sender's high water mark.

This blew up the new SOCK_SEQPACKET.  In particular, it blows up the
use of the PR_ATOMIC on stream sockets and can cause spurious EMSGSIZE
errors to be returned instead of the EWOULDBLOCK that should have been
returned.

Also fix, or partially the resource limit code which tries to reduce the
high water mark when a user is using too many mbufs.  This never worked
well and still doesn't, but it is in better shape now.

Get rid of the crufty code and simply add a flag to the signalsockbuf,
SSB_STOP, to stop the sender.

Also adjust the vkernel to increase the default socket buffer when
connecting to vknet instead of if_tap.  VKE currently issues non-blocking
writes to vknet/tap and we do not want to lose packets for no good reason.

Give the sockbuf structure its own header file and supporting source file.
Move all sockbuf-specific functions from kern/uipc_socket2.c into the new
kern/uipc_sockbuf.c and move all the sockbuf-specific structures from
sys/socketvar.h to sys/sockbuf.h.

Change the sockbuf structure to only contain those fields required to
properly management a chain of mbufs.  Create a signalsockbuf structure
to hold the remaining fields (e.g. selinfo, mbmax, etc).

Change the so_rcv and so_snd structures in the struct socket from
a sockbuf to a signalsockbuf.

Remove the recently added sorecv_direct structure which was being used
to provide a direct mbuf path to consumers for socket I/O.  Use the newly
revamped sockbuf base structure instead.  This gives mbuf consumers
direct access to the sockbuf API functions for use outside of a struct
socket.  This will also allow new API functions to be added to the sockbuf
interface to ease the job of parsing data out of chained mbufs.

Add kernel syscall support for explicit blocking and non-blocking I/O
regardless of the setting applied to the file pointer.

send/sendmsg/sendto/recv/recvmsg/recfrom: New MSG_ flags defined in
sys/socket.h may be passed to these functions to override the settings
applied to the file pointer on a per-I/O basis.

MSG_FBLOCKING	- Force the operation to be blocking
MSG_FNONBLOCKING- Force the operation to be non-blocking

pread/preadv/pwrite/pwritev: These system calls have been renamed and
wrappers will be added to libc.  The new system calls are prefixed with
a double underscore (like getcwd vs __getcwd) and include an additional
flags argument.  The new flags are defined in sys/fcntl.h and may be
used to override settings applied to the file pointer on a per-I/O basis.

Additionally, the internal __ versions of these functions now accept an
offset of -1 to mean 'degenerate into a read/readv/write/writev' (i.e.
use the offset in the file pointer and update it on completion).

O_FBLOCKING	- Force the operation to be blocking
O_FNONBLOCKING	- Force the operation to be non-blocking
O_FAPPEND	- Force the write operation to append (to a regular file)
O_FOFFSET	- (implied of the offset != -1) - offset is valid
O_FSYNCWRITE	- Force a synchronous write
O_FASYNCWRITE	- Force an asynchronous write
O_FUNBUFFERED	- Force an unbuffered operation (O_DIRECT)
O_FBUFFERED	- Force a buffered operation (negate O_DIRECT)

If the flags do not specify an operation (e.g. neither FBLOCKING or
FNONBLOCKING are set), then the settings in the file pointer are used.

The original system calls will become wrappers in libc, without the flags
arguments.  The new system calls will be made available to libc_r to allow
it to perform non-blocking I/O without having to mess with a descriptor's
file flags.

NOTE: the new __pread and __pwrite system calls are backwards compatible
with the originals due to a pad byte that libc always set to 0.
The new __preadv and __pwritev system calls are NOT backwards compatible,
but since they were added to HEAD just two months ago I have decided
to not renumber them either.

NOTE: The subrev has been bumped to 1.5.4 and installworld will refuse to
install if you are not running at least a 1.5.4 kernel.

Fix a sockbuf race.  Currently the m_free*() path can block, due to
objcache_put() blocking when it must access the global depot.  This breaks
the critical section *AND the BGL during a time when the sockbuf state is
inconsistent.  Another process accessing the same sockbuf would then
corrupt it.  Since depot access is fairly rare, this bug typically required
a number of hours to reproduce.

Delay the actual freeing of mbufs until after the sockbuf state has been
updated.  Encapsulate common operations in a procedure, and add additional
assertions.  NULL out sb_lastrecord when it becomes invalid, and add a
considerable amount of debugging code.

SOCKBUF_DEBUG has been added.  Note that this is a VERY EXPENSIVE
kernel compile option which should only be used when specifically debugging
the networking subsystem.

This is a stabilization patch is rather hackish.  A better cleanup will
occur once we are sure we've fixed all the bugs.

Increase the default socket buffer for NFS to deal with linux bugs and to
improve performance.   The default nfs socket buffer is now 65535 bytes,
settable with a sysctl (vfs.nfs.soreserve).

It is my belief that when large data block sizes (32K) are negotiated,
the larger socket buff should improve read-ahead performance and reduce
nfs socket buffer lock contention that occurs with multiple nfsd's.  I
was able to do some testing over GigE and it did seem to help, but problems
with one of the machines made the tests less then reliable.

Credits: Richard Sharpe originally encountered issues with linux NFS
clients that were traced to linux doing a bad job in its delayed-ack code.
David Rhodus created an initial patch which I used as a partial basis for
this commit (circa October 2003).

This patch improves the performance of sendfile(2).  It adds a hash
table of active sf_buf mappings to ensure there is exactly one
(ref-counted) sf_buf for each vm_page.  This saves on the number
of sf_bufs used when sendfile(2) sends the same file over and over
again to multiple connections simultaneously.  It also does lazy
updates on the hw page table when a sf_buf ref count goes to zero,
placing them on a freelist instead, in effect, making sf_bufs a
cache of virtual-to-physical translations with LRU replacement on
the inactive sf_bufs.  Finally, it does a wakeup_one() instead of
a broadcast wakeup() when a free sf_buf becomes available.

This patch roughly corresponds to FreeBSD revs 1.219 and 1.220 of
sys/i386/i386/vm_machdep.c:

  revision 1.219
  date: 2003/11/17 18:22:24;  author: alc;  state: Exp;  lines: +48 -26
  Change the i386's sf_buf implementation so that it never allocates
  more than one sf_buf for one vm_page.  To accomplish this, we add
  a global hash table mapping vm_pages to sf_bufs and a reference
  count to each sf_buf.  (This is similar to the patches for RELENG_4
  at http://www.cs.princeton.edu/~yruan/debox/.)

  For the uninitiated, an sf_buf is nothing more than a kernel virtual
  address that is used for temporary virtual-to-physical mappings by
  sendfile(2) and zero-copy sockets.  As such, there is no reason for
  one vm_page to have several sf_bufs mapping it.  In fact, using more
  than one sf_buf for a single vm_page increases the likelihood that
  sendfile(2) blocks, hurting throughput.
  (See http://www.cs.princeton.edu/~yruan/debox/.)

  revision 1.220
  date: 2003/12/07 22:49:25;  author: alc;  state: Exp;  lines: +10 -9
  Don't remove the virtual-to-physical mapping when an sf_buf is freed.
  Instead, allow the mapping to persist, but add the sf_buf to a free list.
  If a later sendfile(2) or zero-copy send resends the same physical page,
  perhaps with the same or different contents, then the mapping overhead is
  avoided and the sf_buf is simply removed from the free list.

  In other words, the i386 sf_buf implementation now behaves as a cache of
  virtual-to-physical translations using an LRU replacement policy on
  inactive sf_bufs.  This is similar in concept to a part of
  http://www.cs.princeton.edu/~yruan/debox/ patch, but much simpler in
  implementation.  Note: none of this is required on alpha, amd64, or ia64.
  They now use their direct virtual-to-physical mapping to avoid any
  emphemeral mapping overheads in their sf_buf implementations.

Introduce the function iovec_copyin() and it's friend iovec_free().
These remove a great deal of duplicate code in the syscall functions.
For those who like numbers, this patch uses iovec_copyin() four times
in uipc_syscalls.c, two times in linux_socket.c and two times in
43bsd_socket.c.  Would somebody please comment on the inclusion of
sys/malloc.h in sys/uio.h?

Remove sockargs() which was used once in the svr4 emulation code.  It
is replaced with a small piece of code that gets an mbuf and copyin()'s
to it's data region.

Remove the osendfile() syscall which was inapropriately named and placed
in the COMPAT_43 code where it doesn't belong.

Split the socket(), shutdown() and sendfile() syscalls.  All of the
syscalls in kern/uipc_syscalls.c are now split.

Prevent a panic due to m_freem()'ing a dangling pointer in recvmsg(),
orecvmsg(), linux_recvmsg().

This patch completely removes COMPAT_43 from kern/uipc_syscalls.c.
