8d8bc0182e After r193232 rt_tables in vnet.h are no longer indirectly dependent on
the ROUTETABLES kernel option thus there is no need to include opt_route.h
anymore in all consumers of vnet.h and no longer depend on it for module
builds.

Remove the hidden include in flowtable.h as well and leave the two
explicit #includes in ip_input.c and ip_output.c.

86ce6a83d1 Remove the unmaintained University of Michigan NFSv4 client from 8.x
prior to 8.0-RELEASE.  Rick Macklem's new and more feature-rich NFSv234
client and server are replacing it.

4b79449e2f Rather than using hidden includes (with cicular dependencies),
directly include only the header files needed. This reduces the
unneeded spamming of various headers into lots of files.

For now, this leaves us with very few modules including vnet.h
and thus needing to depend on opt_route.h.

a9148abd9d Implement support for RPCSEC_GSS authentication to both the NFS client
and server. This replaces the RPC implementation of the NFS client and
server with the newer RPC implementation originally developed
(actually ported from the userland sunrpc code) to support the NFS
Lock Manager.  I have tested this code extensively and I believe it is
stable and that performance is at least equal to the legacy RPC
implementation.

The NFS code currently contains support for both the new RPC
implementation and the older legacy implementation inherited from the
original NFS codebase. The default is to use the new implementation -
add the NFS_LEGACYRPC option to fall back to the old code. When I
merge this support back to RELENG_7, I will probably change this so
that users have to 'opt in' to get the new code.

To use RPCSEC_GSS on either client or server, you must build a kernel
which includes the KGSSAPI option and the crypto device. On the
userland side, you must build at least a new libc, mountd, mount_nfs
and gssd. You must install new versions of /etc/rc.d/gssd and
/etc/rc.d/nfsd and add 'gssd_enable=YES' to /etc/rc.conf.

As long as gssd is running, you should be able to mount an NFS
filesystem from a server that requires RPCSEC_GSS authentication. The
mount itself can happen without any kerberos credentials but all
access to the filesystem will be denied unless the accessing user has
a valid ticket file in the standard place (/tmp/krb5cc_<uid>). There
is currently no support for situations where the ticket file is in a
different place, such as when the user logged in via SSH and has
delegated credentials from that login. This restriction is also
present in Solaris and Linux. In theory, we could improve this in
future, possibly using Brooks Davis' implementation of variant
symlinks.

Supporting RPCSEC_GSS on a server is nearly as simple. You must create
service creds for the server in the form 'nfs/<fqdn>@<REALM>' and
install them in /etc/krb5.keytab. The standard heimdal utility ktutil
makes this fairly easy. After the service creds have been created, you
can add a '-sec=krb5' option to /etc/exports and restart both mountd
and nfsd.

The only other difference an administrator should notice is that nfsd
doesn't fork to create service threads any more. In normal operation,
there will be two nfsd processes, one in userland waiting for TCP
connections and one in the kernel handling requests. The latter
process will create as many kthreads as required - these should be
visible via 'top -H'. The code has some support for varying the number
of service threads according to load but initially at least, nfsd uses
a fixed number of threads according to the value supplied to its '-n'
option.

7ad7a38277 Work around the fact that nfsclient SRCS must include
nfs_diskless.c if NFS_ROOT is in effect, e.g., present
in the kernel config file.  Otherwise the built module
won't load due to an undefined reference to nfs_setup_diskless.

822923447e Let modules use the kernel's opt_*.h files if built along with
the kernel by wrapping all targets for fake opt_*.h files in
.if defined(KERNBUILDDIR).  Thus, such fake files won't be
created at all if modules are built with the kernel.

Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.

0ac4013324 Change the following environment variables to kernel options:
bootp -> BOOTP
    bootp.nfsroot -> BOOTP_NFSROOT
    bootp.nfsv3 -> BOOTP_NFSV3
    bootp.compat -> BOOTP_COMPAT
    bootp.wired_to -> BOOTP_WIRED_TO

- i.e. back out the previous commit.  It's already possible to
pxeboot(8) with a GENERIC kernel.

59e1ebc9b5 Change the following kernel options to environment variables:
BOOTP -> bootp
    BOOTP_NFSROOT -> bootp.nfsroot
    BOOTP_NFSV3 -> bootp.nfsv3
    BOOTP_COMPAT -> bootp.compat
    BOOTP_WIRED_TO -> bootp.wired_to

This lets you PXE boot with a GENERIC kernel by putting this sort of thing
in loader.conf:

    bootp="YES"
    bootp.nfsroot="YES"
    bootp.nfsv3="YES"
    bootp.wired_to="bge1"

or even setting the variables manually from the OK prompt.

e0ce91e18b Quick hack to make the nfsclient.ko loadable again. This brings in
the nfsv4 files.  It is intended to be a short-term bridge while
alfred deals with the problem in a better way (eg, don't hesitate to
back this out when the real fix comes along).  I've not heard back
from alfred in a few hours and other people are hitting this problem.

abc370fa85 Moved nfs_diskless setup code from autoconf.c to nfsclient/nfs_diskless.c
so that it is MI.  Allow nfs_mountroot to return an error if the nfs_diskless
struct is not valid, rather than panicing later on.  Call nfs_setup_diskless()
from nfs_mountroot if NFS_ROOT is defined, like bootpc_init().  Removed legacy
root mount support for sparc64, and enabled NFS_ROOT by default.

56ca39961b Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk.  This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.

NFS_*TIMO should possibly be converted to sysctl vars (jkh's suggestion),
but in some cases it looks like nfs keeps a copy of the value in a struct

hash sizes are already ifdef'd KERNEL, so there aren't userland inpact
from them...
