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.

|
|
.Sh SYNOPSIS

.Op Fl d Ar debug_level
|
|
.Op Fl g Ar grace period
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
daemon provides monitored and unmonitored file and record locking services
|
|
in an NFS environment.
|
|
To monitor the status of hosts requesting locks,
|
|
the locking daemon typically operates in conjunction
|
|
with
|
|
.Xr rpc.statd 8 .
|
|
.Pp
|
|
Options and operands available for
|
|
.Nm :
|
|
.Bl -tag -width indent
|
|
.It Fl d
|
|
The
|
|
.Fl d
|
|
option causes debugging information to be written to syslog, recording
|
|
all RPC transactions to the daemon.
|
|
These messages are logged with level
|
|
.Dv LOG_DEBUG
|
|
and facility
|
|
.Dv LOG_DAEMON .
|
|
Specifying a
|
|
.Ar debug_level
|
|
of 1 results
|
|
in the generation of one log line per protocol operation.
|
|
Higher
|
|
debug levels can be specified, causing display of operation arguments
|
|
and internal operations of the daemon.
|
|
.It Fl g
|
|
The
|
|
.Fl g
|
|
option allow to specify the
|
|
.Ar grace period ,
|
|
in seconds.
|
|
During the grace period
|
|
.Nm
|
|
only accepts requests from hosts which are reinitialising locks which
|
|
existed before the server restart.
|
|
Default is 30 seconds.
|
|
.El
|
|
.Pp
|
|
Error conditions are logged to syslog, irrespective of the debug level,
|
|
using log level
|
|
.Dv LOG_ERR
|
|
and facility
|
|
.Dv LOG_DAEMON .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
daemon must NOT be invoked by
|
|
.Xr inetd 8
|
|
because the protocol assumes that the daemon will run from system start time.
|
|
Instead, it should be configured in
|
|
.Xr rc.conf 5
|
|
to run at system startup.

|
|
.Sh BUGS
|
|
The current implementation provides only the server side of the protocol
|
|
(i.e., clients running other OS types can establish locks on a
|
|
.Fx
|
|
/
|
|
.Nx
|
|
fileserver,
|
|
but there is currently no means for a
|
|
.Fx
|
|
/
|
|
.Nx
|
|
client to establish locks).
|
|
.Pp
|
|
The current implementation serialises locks requests that could be shared.
|
|
.Sh STANDARDS
|
|
The implementation is based on the specification in
|
|
.Rs
