eda8b2821f When getting back an NLM DENIED response for a requested lock from the
server, map it to EAGAIN locally rather than EACCES.  The NLM spec
indicates the DENIED corresponds to lock contention, not a permission
failure.  This fixes O_EXLOCK/O_SHLOCK with O_NONBLOCK, which would
previously give a permission error, which in turn fixes things
like mailq(8) and lockf(1) over NFS.

86eb7cbada Avoid registering for a lock on the server in the event the NFS client
has requested the lock in a non-blocking form, instead returning an
immediate failure.  This appears to help reduce one of my "locks get
lost" symptoms involving lockf(1), which attempts a non-blocking lock
attempt before actually blocking on the lock.  At this point the client
still gets back EACCES, which is an issue we're still working.

1870b993d0 When receiving NLM_GRANTED_RES or NLM4_GRANTED_RES lock granted messages
from the NFS server, following contention on a lock by this or another
client, immediately notify the waiting process that the lock has been
granted via a wakeup.  Without this change, the client rpc.lockd will
not wakeup the waiting process until it next re-polls the lock (sometime
in the next ten seconds), which can lead to marked latency across all
potential lockers, as the lock is held by the client for the duration.

e4b0fede2c Use char foo[] = "BAR" to avoid direct assignment of const char * into char *.
rpcgen can't really make those fields const because the remote side might
want to munge them, so we need to pass non-const in.  Hackish, but should
work.

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).

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.
