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 are part of the RPC
|
|
library which allows C language programs to make procedure
|
|
calls on other machines across the network.
|
|
.Pp
|
|
These routines can be called by the server side
|
|
dispatch function if there is any error in the
|
|
transaction with the client.
|
|
.Sh Routines
|
|
See
|
|
.Xr rpc 3
|
|
for the definition of the
|
|
.Vt SVCXPRT
|
|
data structure.
|
|
.Bl -tag -width XXXXX
|
|
.It Fn svcerr_auth
|
|
Called by a service dispatch routine that refuses to perform
|
|
a remote procedure call due to an authentication error.
|
|
.It Fn svcerr_decode
|
|
Called by a service dispatch routine that cannot successfully
|
|
decode the remote parameters
|
|
(see
|
|
.Fn svc_getargs
|
|
in
|
|
.Xr rpc_svc_reg 3 ) .
|
|
.It Fn svcerr_noproc
|
|
Called by a service dispatch routine that does not implement
|
|
the procedure number that the caller requests.
|
|
.It Fn svcerr_noprog
|
|
Called when the desired program is not registered with the
|
|
RPC package.
|
|
Service implementors usually do not need this routine.
|
|
.It Fn svcerr_progvers
|
|
Called when the desired version of a program is not registered with the
|
|
RPC package.
|
|
.Fa low_vers
|
|
is the lowest version number,
|
|
and
|
|
.Fa high_vers
|
|
is the highest version number.
|
|
Service implementors usually do not need this routine.
|
|
.It Fn svcerr_systemerr
|
|
Called by a service dispatch routine when it detects a system
|
|
error not covered by any particular protocol.
|
|
For example, if a service can no longer allocate storage,
|
|
it may call this routine.
|
|
.It Fn svcerr_weakauth
|
|
Called by a service dispatch routine that refuses to perform
|
|
a remote procedure call due to insufficient (but correct)
|
|
authentication parameters.
|
|
The routine calls
|
|
.Fn svcerr_auth "xprt" "AUTH_TOOWEAK" .
