There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

.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.
|
|
.Pp
|
|
.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.
|
|
.Pp
|
|
.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 ) .
|
|
.Pp
|
|
.It Fn svcerr_noproc
|
|
Called by a service dispatch routine that does not implement
|
|
the procedure number that the caller requests.
|
|
.Pp
|
|
.It Fn svcerr_noprog
|
|
Called when the desired program is not registered with the
|
|
RPC package.
|
|
Service implementors usually do not need this routine.
|
|
.Pp
|
|
.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.
|
|
.Pp
|
|
.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.
|
|
.Pp
|
|
.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" .
