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 that allows C language programs to make procedure
|
|
calls on other machines across the network,
|
|
with desired authentication.
|
|
.Pp
|
|
These routines are normally called after creating the
|
|
.Dv CLIENT
|
|
handle.
|
|
The
|
|
.Fa cl_auth
|
|
field of the
|
|
.Dv CLIENT
|
|
structure should be initialized by the
|
|
.Dv AUTH
|
|
structure returned by some of the following routines.
|
|
The client's authentication information
|
|
is passed to the server when the
|
|
RPC
|
|
call is made.
|
|
.Pp
|
|
Only the
|
|
.Dv NULL
|
|
and the
|
|
.Dv SYS
|
|
style of authentication is discussed here.
|
|
.Sh ROUTINES
|
|
.Bl -tag -width authsys_create_default()
|
|
.It Fn auth_destroy
|
|
A function macro that destroys the authentication
|
|
information associated with
|
|
.Fa auth .
|
|
Destruction usually involves deallocation
|
|
of private data structures.
|
|
The use of
|
|
.Fn auth
|
|
is undefined after calling
|
|
.Fn auth_destroy .
|
|
.Pp
|
|
.It Fn authnone_create
|
|
Create and return an RPC
|
|
authentication handle that passes nonusable
|
|
authentication information with each remote procedure call.
|
|
This is the default authentication used by RPC.
|
|
.Pp
|
|
.It Fn authsys_create
|
|
Create and return an RPC authentication handle that contains
|
|
.Dv AUTH_SYS
|
|
authentication information.
|
|
The parameter
|
|
.Fa host
|
|
is the name of the machine on which the information was
|
|
created;
|
|
.Fa uid
|
|
is the user's user ID;
|
|
.Fa gid
|
|
is the user's current group ID;
|
|
.Fa len
|
|
and
|
|
.Fa aup_gids
|
|
refer to a counted array of groups to which the user belongs.
|
|
.Pp
|
|
.It Fn authsys_create_default
|
|
Call
|
|
.Fn authsys_create
|
|
with the appropriate parameters.
