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
|
|
.Pa /etc/netconfig
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
file defines a list of
|
|
.Dq transport names ,
|
|
describing their semantics and protocol.
|
|
In
|
|
.Fx ,
|
|
this file is only used by the RPC library code.
|
|
.Pp
|
|
Entries have the following format:
|
|
.Pp
|
|
.Ar network_id semantics flags family protoname device libraries
|
|
.Pp
|
|
Entries consist of the following fields:
|
|
.Bl -tag -width network_id
|
|
.It Ar network_id
|
|
The name of the transport described.
|
|
.It Ar semantics
|
|
Describes the semantics of the transport.
|
|
This can be one of:
|
|
.Bl -tag -width tpi_cots_ord -offset indent
|
|
.It Sy tpi_clts
|
|
Connectionless transport.
|
|
.It Sy tpi_cots
|
|
Connection-oriented transport
|
|
.It Sy tpi_cots_ord
|
|
Connection-oriented, ordered transport.
|
|
.It Sy tpi_raw
|
|
A raw connection.
|
|
.El
|
|
.It Ar flags
|
|
This field is either blank (specified by
|
|
.Dq Li - ) ,
|
|
or contains a
|
|
.Dq Li v ,
|
|
meaning visible to the
|
|
.Xr getnetconfig 3
|
|
function.
|
|
.It Ar family
|
|
The protocol family of the transport.
|
|
This is currently one of:
|
|
.Bl -tag -width loopback -offset indent
|
|
.It Sy inet6
|
|
The IPv6
|
|
.Pq Dv PF_INET6
|
|
family of protocols.
|
|
.It Sy inet
|
|
The IPv4
|
|
.Pq Dv PF_INET
|
|
family of protocols.
|
|
.It Sy loopback
|
|
The
|
|
.Dv PF_LOCAL
|
|
protocol family.
|
|
.El
|
|
.It Ar protoname
|
|
The name of the protocol used for this transport.
|
|
Can currently be either
|
|
.Sy udp ,
|
|
.Sy tcp
|
|
or empty.
|
|
.It Ar device
|
|
This field is always empty in
|
|
.Fx .
|
|
.It Ar libraries
|
|
This field is always empty in
|
|
.Fx .
|
|
.El
|
|
.Pp
|
|
The order of entries in this file will determine which transport will
|
|
be preferred by the RPC library code, given a match on a specified
|
|
network type.
|
|
For example, if a sample network config file would look like this:
|
|
.Bd -literal -offset indent
|
|
udp6 tpi_clts v inet6 udp - -
|
|
tcp6 tpi_cots_ord v inet6 tcp - -
|
|
udp tpi_clts v inet udp - -
|
|
tcp tpi_cots_ord v inet tcp - -
|
|
rawip tpi_raw - inet - - -
|
|
local tpi_cots_ord - loopback - - -
|
|
.Ed
|
|
.Pp
|
|
then using the network type
|
|
.Sy udp
|
|
in calls to the RPC library function (see
|
|
.Xr rpc 3 )
|
|
will make the code first try
|
|
.Sy udp6 ,
|
|
and then
|
|
.Sy udp .
|
|
.Pp
|
|
.Xr getnetconfig 3
|
|
and associated functions will parse this file and return structures of
|
|
the following format:
|
|
.Bd -literal
|
|
struct netconfig {
|
|
