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.

.Sh DESCRIPTION
|
|
|
|
|
These routines allow client C programs to make procedure
|
|
|
|
|
calls to the RPC binder service.
|
|
|
|
|
(see
|
|
|
|
|
.Xr rpcbind 8 )
|
|
|
|
|
maintains a list of mappings between programs
|
|
|
|
|
and their universal addresses.

|
|

|
.Bl -tag -width XXXXX
|
|
|
|
|
.It Fn rpcb_getmaps
|
|
|
|
|
An interface to the rpcbind service,
|
|
|
|
|
which returns a list of the current
|
|
|
|
|
RPC program-to-address mappings on
|
|
|
|
|
.Fa host .
|
|
|
|
|
It uses the transport specified through
|
|
|
|
|
.Fa netconf
|
|
|
|
|
to contact the remote rpcbind
|
|
|
|
|
service on
|
|
|
|
|
.Fa host .
|
|
|
|
|
This routine will return
|
|
|
|
|
.Dv NULL ,
|
|
|
|
|
if the remote rpcbind could not be contacted.
|
|
|
|
|
.It Fn rpcb_getaddr
|
|
|
|
|
An interface to the rpcbind
|
|
|
|
|
service, which finds the address of the service on
|
|
|
|
|
.Fa host
|
|
|
|
|
that is registered with program number
|
|
|
|
|
.Fa prognum ,
|
|
|
|
|
version
|
|
|
|
|
.Fa versnum ,
|
|
|
|
|
and speaks the transport protocol associated with
|
|
|
|
|
.Fa netconf .
|
|
|
|
|
The address found is returned in
|
|
|
|
|
.Fa svcaddr .
|
|
|
|
|
.Fa svcaddr
|
|
|
|
|
should be preallocated.
|
|
|
|
|
This routine returns
|
|
|
|
|
.Dv TRUE
|
|
|
|
|
if it succeeds.
|
|
|
|
|
A return value of
|
|
|
|
|
.Dv FALSE
|
|
|
|
|
means that the mapping does not exist
|
|
|
|
|
or that the RPC
|
|
|
|
|
system failed to contact the remote
|
|
|
|
|
rpcbind service.
|
|
|
|
|
In the latter case, the global variable
|
|
|
|
|
.Va rpc_createerr
|
|
|
|
|
(see
|
|
|
|
|
.Xr rpc_clnt_create 3 )
|
|
|
|
|
contains the
|
|
|
|
|
RPC status.
|
|
|
|
|
.It Fn rpcb_gettime
|
|
|
|
|
This routine returns the time on
|
|
|
|
|
.Fa host
|
|
|
|
|
in
|
|
|
|
|
.Fa timep .
|
|
|

|
If
|
|
|
|

.Fa host
|
|
|
|
|
is
|
|
|
|
|
.Dv NULL ,
|
|
|
|
|
.Fn rpcb_gettime
|
|
|
|
|
returns the time on its own machine.
|
|
|
|
|
This routine returns
|
|
|
|
|
.Dv TRUE
|
|
|
|
|
if it succeeds,
|
|
|
|
|
.Dv FALSE
|
|
|
|
|
if it fails.
|
|
|
|
|
.Fn rpcb_gettime
|
|
|
|
|
can be used to synchronize the time between the
|
|
|
|
|
client and the remote server.
|
|
|
|
|
.It Fn rpcb_rmtcall
|
|
|
|
|
An interface to the rpcbind service, which instructs
|
|
|
|
|
rpcbind on
|
|
|
|
|
.Fa host
|
|
|
|
|
to make an RPC
|
|
|
|
|
call on your behalf to a procedure on that host.
|
|
|
|
|
The
|
|
|
|
|
.Fn netconfig
|
|
|
|
|
structure should correspond to a connectionless transport.
|
|
|
|
|
The parameter
|
|
|
|
|
.Fa svcaddr
|
|
|
|
|
will be modified to the server's address if the procedure succeeds
|
|
|
|
|
(see
|
|
|
|
|
.Fn rpc_call
|
|
|
|
|
and
|

|
|
|
|
|
in

|
|
|
|
for the definitions of other parameters).
|
|
|
|
|
.Pp
|
|
|
|
|
This procedure should normally be used for a
|
|
|
|
|
.Dq ping
|
|
|
|
|
and nothing else.
|
|
|
|
|
This routine allows programs to do lookup and call, all in one step.

|
|
|
|
Note: Even if the server is not running
|
|
|
|
|
.Fn rpcb_rmtcall
|
|
|
|
|
does not return any error messages to the caller.
|
|
|
|
|
In such a case, the caller times out.
|
|
|
|
|
.Pp
|
|
|
|
|
Note:
|
|
|
|
|
.Fn rpcb_rmtcall
|
|
|
|
|
is only available for connectionless transports.
|
|
|
|
|
.It Fn rpcb_set
|
|
|
|
|
An interface to the rpcbind
|
|
|
|
|
service, which establishes a mapping between the triple
|
|
|
|
|
.Bq Fa prognum , versnum , netconf->nc_netid
|
|
|
|
|
and
|
|
|
|
|
.Fa svcaddr
|
|
|
|
|
on the machine's rpcbind
|
|
|
|
|
service.
|
|
|
|
|
The value of
|
|
|
|
|
.Fa nc_netid
|
|
|
|
|
must correspond to a network identifier that is defined by the
|
|
|
|
|
netconfig database.
|
|
|
|
|
This routine returns

If there already exists such an entry with rpcbind,

|
|
|
|
.Fn rpcb_set
|
|
|
|
|
will fail.
|
|
|
|
|
.It Fn rpcb_unset
|
|
|
|
|
An interface to the rpcbind
|
|
|
|
|
service, which destroys the mapping between the triple
|
|
|
|
|
.Bq Fa prognum , versnum , netconf->nc_netid
|
|
|
|
|
and the address on the machine's rpcbind
|

|
service.

If
|

is

.Dv NULL ,
|

.Fn rpcb_unset

|

destroys all mapping between the triple

|
|
|
.Bq Fa prognum , versnum , No all-transports
|
|
|
|
|
and the addresses on the machine's rpcbind service.
|
|
|
|
|
This routine returns
|
|
|
|
|
.Dv TRUE
|
|

if it succeeds,
|
|
|
|
|
.Dv FALSE
|

Only the owner of the service or the super-user can destroy the mapping.
