bd18fd57db DIRDEPS_BUILD: Regenerate without local dependencies.
These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

WITH_META_MODE we get auto objdir creation, the ability to

9745de4c2c When mountd is creating sockets, it iterates over all addresses specified
in the "hosts" array and eventually looks up the network address with
getaddrinfo(). At one point it checks for a numeric address and if it
sees one, it sets a hint parameter to force getaddrinfo to interpret the
host as a numeric address. However that hint is not cleared for subsequent
iterations of the loop and if any hosts seen after this point are host names,
getaddrinfo will fail on the name.  The result of this bug is that you cannot
pass a host name to the -h flag.

Unfortunately, the first iteration will either process ::1 or 127.0.0.1,
so the flag is set on the first iteration and all host names will fail
to be processed.

The same bug applies to rpc.lockd and rpc.statd, so fix them too.

795b2dc06a Fix the nfs related daemons so that they don't intermittently
fail with "bind: address already in use". This problem was reported
to the freebsd-stable@ mailing list on Feb. 19 under the subject
heading "statd/lockd startup failure" by george+freebsd at m5p dot com.
The problem is that the first combination of {udp,tcp X ipv4,ipv6}
would select a port# dynamically, but one of the other three combinations
would have that port# already in use. The patch is somewhat involved
because it was requested by dougb@ that the four combinations use the
same port# wherever possible. The patch splits the create_service()
function into two functions. The first goes as far as bind(2) in a
loop for up to GETPORT_MAXTRY - 1 times, attempting to use the same port#
for all four cases. If these attempts fail, the last attempt allows
the 4 cases to use different port #s. After this function has succeeded,
the second function, called complete_service(), does the rest of what
create_service() did.
The three daemons mountd, rpc.lockd and rpc.statd all have a
create_service() function that is patched in a similar way. However,
create_service() has non-trivial differences for the three daemons
that made it impractical to share the same functions between them.

c675522fc4 Re-implement the client side of rpc.lockd in the kernel. This implementation
provides the correct semantics for flock(2) style locks which are used by the
lockf(1) command line tool and the pidfile(3) library. It also implements
recovery from server restarts and ensures that dirty cache blocks are written
to the server before obtaining locks (allowing multiple clients to use file
locking to safely share data).

dfdcada31e Add the new kernel-mode NFS Lock Manager. To use it instead of the
user-mode lock manager, build a kernel with the NFSLOCKD option and
add '-k' to 'rpc_lockd_flags' in rc.conf.

Highlights include:

* Thread-safe kernel RPC client - many threads can use the same RPC
  client handle safely with replies being de-multiplexed at the socket
  upcall (typically driven directly by the NIC interrupt) and handed
  off to whichever thread matches the reply. For UDP sockets, many RPC
  clients can share the same socket. This allows the use of a single
  privileged UDP port number to talk to an arbitrary number of remote
  hosts.

* Single-threaded kernel RPC server. Adding support for multi-threaded
  server would be relatively straightforward and would follow
  approximately the Solaris KPI. A single thread should be sufficient
  for the NLM since it should rarely block in normal operation.

* Kernel mode NLM server supporting cancel requests and granted
  callbacks. I've tested the NLM server reasonably extensively - it
  passes both my own tests and the NFS Connectathon locking tests
  running on Solaris, Mac OS X and Ubuntu Linux.

* Userland NLM client supported. While the NLM server doesn't have
  support for the local NFS client's locking needs, it does have to
  field async replies and granted callbacks from remote NLMs that the
  local client has contacted. We relay these replies to the userland
  rpc.lockd over a local domain RPC socket.

* Robust deadlock detection for the local lock manager. In particular
  it will detect deadlocks caused by a lock request that covers more
  than one blocking request. As required by the NLM protocol, all
  deadlock detection happens synchronously - a user is guaranteed that
  if a lock request isn't rejected immediately, the lock will
  eventually be granted. The old system allowed for a 'deferred
  deadlock' condition where a blocked lock request could wake up and
  find that some other deadlock-causing lock owner had beaten them to
  the lock.

* Since both local and remote locks are managed by the same kernel
  locking code, local and remote processes can safely use file locks
  for mutual exclusion. Local processes have no fairness advantage
  compared to remote processes when contending to lock a region that
  has just been unlocked - the local lock manager enforces a strict
  first-come first-served model for both local and remote lockers.

nfsd(8), in mountd(8), and in rpc.statd(8)

-h bindip
Specify specific IP addresses to bind to for TCP and UDP requests.
This option may be specified multiple times.  If no -h option is
specified, rpc.lockd will bind to INADDR_ANY.  Note that when specifying
IP addresses with -h, rpc.lockd will automatically add 127.0.0.1 and
if IPv6 is enabled, ::1 to the list.

251bb62d63 When a user is in more than 16 groups the call to authunix_create() will
result in abort() beeing called. This is because there is a limit of
the number of groups in the RPC which is 16. When the actual number of
groups is too large it results in xdr_array() returning an error which,
in turn, authunix_create() handles by just calling abort().

Fix this by passing only the first 16 groups to authunix_create().
