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.

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).

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.statd will bind to INADDR_ANY. Note that when specifying
IP addresses with -h, rpc.statd will automatically add 127.0.0.1 and if
IPv6 is enabled, ::1 to the list.

mmap() succeeded. Since rpc.statd does not have fallback code to
implement the functionality needed to operate on the status file if
it is not memory mapped, rpc.statd should use err() to force the process
to exit if the mmap() call fails.

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.
