I was considering committing all these patches one by one, but as
discussed with brooks@, there is no need to do this. If we ever
need/want to merge these changes back, it is still possible to do this
per application.

20d0a5e544 Modify nfsd.c to add support for the experimental nfs server.
This includes the addition of a new flag "-4" that will force
use of the experimental server with nfsv4 support in it. This
commit also adds two new man pages to the repository that are
NFSv4 specific. One describes the file used by the server to
restart nfsv4 services safely. The other is a brief overview
of nfsv4 and its setup.

a9148abd9d Implement support for RPCSEC_GSS authentication to both the NFS client
and server. This replaces the RPC implementation of the NFS client and
server with the newer RPC implementation originally developed
(actually ported from the userland sunrpc code) to support the NFS
Lock Manager.  I have tested this code extensively and I believe it is
stable and that performance is at least equal to the legacy RPC
implementation.

The NFS code currently contains support for both the new RPC
implementation and the older legacy implementation inherited from the
original NFS codebase. The default is to use the new implementation -
add the NFS_LEGACYRPC option to fall back to the old code. When I
merge this support back to RELENG_7, I will probably change this so
that users have to 'opt in' to get the new code.

To use RPCSEC_GSS on either client or server, you must build a kernel
which includes the KGSSAPI option and the crypto device. On the
userland side, you must build at least a new libc, mountd, mount_nfs
and gssd. You must install new versions of /etc/rc.d/gssd and
/etc/rc.d/nfsd and add 'gssd_enable=YES' to /etc/rc.conf.

As long as gssd is running, you should be able to mount an NFS
filesystem from a server that requires RPCSEC_GSS authentication. The
mount itself can happen without any kerberos credentials but all
access to the filesystem will be denied unless the accessing user has
a valid ticket file in the standard place (/tmp/krb5cc_<uid>). There
is currently no support for situations where the ticket file is in a
different place, such as when the user logged in via SSH and has
delegated credentials from that login. This restriction is also
present in Solaris and Linux. In theory, we could improve this in
future, possibly using Brooks Davis' implementation of variant
symlinks.

Supporting RPCSEC_GSS on a server is nearly as simple. You must create
service creds for the server in the form 'nfs/<fqdn>@<REALM>' and
install them in /etc/krb5.keytab. The standard heimdal utility ktutil
makes this fairly easy. After the service creds have been created, you
can add a '-sec=krb5' option to /etc/exports and restart both mountd
and nfsd.

The only other difference an administrator should notice is that nfsd
doesn't fork to create service threads any more. In normal operation,
there will be two nfsd processes, one in userland waiting for TCP
connections and one in the kernel handling requests. The latter
process will create as many kthreads as required - these should be
visible via 'top -H'. The code has some support for varying the number
of service threads according to load but initially at least, nfsd uses
a fixed number of threads according to the value supplied to its '-n'
option.

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.

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.

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.
