3f7c86a8c3 Bump the default maximum on nfsd processes from 20 to 256. Real-world
measurements suggest that higher degrees of parallelism for large
numbers of clients help performance substantially.

6f52836b84 ANSI'fy nfsd(8) and some minor changes to make it WARNS=6 clean.
This commit does not affect the code generated, as proven by md5'ing
resulting binaries.

Bump WARNS accordingly.

0be1e825d6 Problem:
When an NFS server is port-scanned nfsd sometimes exits. This has
  happened 3 times the last few weeks.

  Nfsd has been written to exit when accept(2) fails. Unfortunately
  accept can sometimes make a "normal" return with errno ECONNABORTED
  and in this case nfsd exits prematurely.

Solution:

  Check for ECONNABORTED (and also EINTR, since nfsd uses signals)
  and continue.

4cc03f63d1 Initialize sockbits variable with FD_ZERO, to avoid passing a fd_set
with random garbage in lower bits corresponding to stdin, stdout and
stderr to select(2).

This fixes the problem with nfsd sometimes getting stuck in a tight
select(2) loop eating 100% CPU time.

fef7dd5a5f When nfsd was started with only UDP servers, the master nfsd would
spin in a loop eating CPU time. This bug has existed since the
TI-RPC import. The problem is that we should only enter the select
loop if at least one TCP server was started.  Fix this by having
the master nfsd become a UDP server itself if there are no TCP
servers.

Also improve/correct the code for cleaning up slave nfsd processes
and unregistering with rpcbind when the master nfsd exits.

One issue that remains open is that if a slave nfsd dies, then all
nfsds will shut down. This is because nfssvc() in the master nfsd
returns 0 when the master nfsd receives a SIGCHLD.

e0a509bb08 Don't call daemon() and setup our signal handlers until after we check
and do the unregister/reregister work.

Don't call syslog in the unregister/reregister code as we haven't called
openlog() yet.

Be a more conservative about accepting errno values from socket(2),
only EPROTONOSUPPORT means that the kernel isn't supporting it
something like INET6.  The other possible errnos would be returned
if there was a mistake in the socket(2) call so remove them from the
list of "acceptable" return values.

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.

92fc2acf51 Give nfsd the ability to bind to specific IP addresses through the -h
option and add explicit option to bind to the wildcard address.  The
    default is to bind to the wildcard address when no -h option has been
    specified and thus backwards compatibility is maintained.

09802b4a89 The version of setproctitle() inside nfsd was busted. It was not terminating
the argv array, causing parts of the argv[0] to be picked up several times
by libkvm, causing strange ps results for the nfs-server and nfs-master
processes.. :-]

(How many copies of setproctitle() do we need anyway?  NetBSD has it in
 libc and BSDI have it in libutil.)

a62dc40654 Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount).  The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server.  It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs.  Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.
