with export lines where the same hostname was specified more than once
(this happens a lot with netgroups sometimes). Recently I discovered
that it needs to be hacked to deal with multiple instances of the
same IP address too.
I've been using this modification locally for several months with no
hassles.
an export line) is unresolvable, make a note of it via syslog and skip
that individual host instead of skipping the entire line.

Instead, reverse the order of the testing, so if a symbolic name starts with
a digit, we'll see if we can make a network address out of it first. If
that fails, then we'll call getnet...
nfs requests from non-privileged ports.
Change mountd such that it does never set this variable, but only clears
it when run with -n. Also document this in the man page.
(presumably because the kernel is old). Moved the declaration of a
variable realated to this sysctl outside of an unrelated ifdef.
Not fixed:
- this sysctl is badly named (nfs occurs twice).
- it's silly to have for FreeBSD in FreeBSD code, especially when
only half of the FreeBSD-dependent code is ifdefed.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
hostname/IP twice on same line in /etc/exports' fix from dumping core

The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server. It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.
Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs. Servers will need to build and
install /usr/sbin/mountd.
NFS diskless support is untested.

you to push the same host into its NFS export lists twice, but mountd
tries to do it anyway. This means that putting:
/some_file_system -ro host1 host1
in your /etc/exports file causes an error. This is bogus: mountd should be
smart enough to ignore the second instance of host1. This can be a problem
in some configurations that use netgroups. For example, each host in my
netgroups database is has two entries:
startide (startide,-,) (startide.ctr.columbia.edu,-,)
When mountd sees this, it tries to put startide.ctr.columbia.edu into the
export list *twice*. Just listing 'startide' /etc/exports list will also
screw up because mountd will try to resolve the netgroup 'startide' instead
of the hostname 'startide.'
My solution is watch for duplicate entries in get_host() and mark them
as grouptype GT_IGNORE, which do_mount() will now cheefully throw away.
This is a bit of a kludge, but it was the least obtrusive fix I could
come up with.
Also silenced a compiler warning: arguments passwd to xdr_long() should
be u_long, not int. :)
