4b4ec9b800 Fix boundry condition in lock management:
Alfred, I took a look at retry_blockingfilelocklist() and the
 solution seemed  simple enough. Please correct me if I am wrong.
 It seems said routine doesn't  take into account boundary conditions
 when putting back file_lock entries into the blocked lock-list.
 Specifically, it fails when the file_lock being put back is the
 last element in the list, and when it is the only element in the
 list.  I've included a patch below.

 Basically, it introduces another variable: pfl, which keeps track
 of the list  item before ifl. That way if nfl is NULL, ifl gets
 inserted after pfl. If pfl  is also NULL, then it gets inserted
 at the head of the list (since it was the  only element in the
 list).

5f07c7b294 This completes the all partial file locking under NFS. The underlying
file is still completely covered by a flock(2) style lock, but we'll tackle
that at a later date.

b6dc41baf1 Cleanup.
use LIST_FOREACH,

add prototypes (functions should be made static probably),

change DEBUG=1 to LOCKD_DEBUG,

K&R function instantiation for functions with long args lists,

Move comments about functions from within to above the function,

Simplified some if/else logic and reduced nested blocks.

parens around 'return' argument (return FOO -> return (FOO))

7e589b0b6e This adds in the full HW locking capability and should now make my rewrite
of the rpc.lockd fully compliant with the old file locking semantics.

Andrew will dig into the statd code next and then will attack the split
locking.

This also backs out a lot of the work I've done on making the code
more conformant with non-written style rules, but we'll revisit that
later.

64b829d192 leverage fixed fifo implementation (rev 1.56 of
src/sys/fs/fifofs/fifo_vnops.c) to serve locks better, my previous
workaround for lack of decent fifo system wasn't cutting it,
particularly the kernel would send a message down the fifo and
immediately close it, this would lead to delayed unlock requests
being seen by the lockd causing all sorts of badness.

Basically, don't reopen the fifo, just select(2) on it.

8360efbd6c Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and
associated changes that had to happen to make this possible as well as
bugs fixed along the way.

  Bring in required TLI library routines to support this.

  Since we don't support TLI we've essentially copied what NetBSD
  has done, adding a thin layer to emulate direct the TLI calls
  into BSD socket calls.

  This is mostly from Sun's tirpc release that was made in 1994,
  however some fixes were backported from the 1999 release (supposedly
  only made available after this porting effort was underway).

  The submitter has agreed to continue on and bring us up to the
  1999 release.

  Several key features are introduced with this update:
    Client calls are thread safe. (1999 code has server side thread
    safe)
    Updated, a more modern interface.

  Many userland updates were done to bring the code up to par with
  the recent RPC API.

  There is an update to the pthreads library, a function
  pthread_main_np() was added to emulate a function of Sun's threads
  library.

  While we're at it, bring in NetBSD's lockd, it's been far too
  long of a wait.

  New rpcbind(8) replaces portmap(8) (supporting communication over
  an authenticated Unix-domain socket, and by default only allowing
  set and unset requests over that channel). It's much more secure
  than the old portmapper.

  Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
  to support TI-RPC and to support IPV6.

  Umount(8) is also fixed to unmount pathnames longer than 80 chars,
  which are currently truncated by the Kernel statfs structure.

414a35e60a Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

503d2aa8a2 Import Jan 15 version of Andrew Gordon <andrew.gordon@net-tel.co.uk>'s
stub lockd.

This implements just the protocol, but does not interact with the kernel.
It says "Yes!" to all requests.  This is useful if you have people using
tools that do locking for no reason (eg: some PC NFS systems running some
Microsoft products) and will happily report they couldn't lock the file
and merrily proceed anyway.  Running this will not change the reliability of
sharing files, it'll just keep it out of everybody's face.
