linux-nfs/NEW

This is the Linux kernel NFS daemon 1.4.7. It is based on linux-nfs
0.4.22. It is tested on Linux/alpha and Linux/x86 running glibc 2.1.1.

WARNING: The NFS servers in Linux 2.2 to 2.2.11 are not compatible with
other NFS client implemenations. If you plan to use Linux 2.2.x as an
NFS server for non-Linux NFS clients, you should apply the patches
enlosed here.

linux-2.2.7-sunrpc.patch, nfsd-2.2.7-2.lockd.patch, nfsd-2.2.7-3.patch
and nfsd-2.2.7-nfsfh.patch are required for Linux 2.2.7 to 2.2.11.
For other kernel versions, they have to be applied by hand if they are
still needed.

For Linux 2.2.7 to 2.2.10, nfsd-2.2.7-1.lock.patch is also required.

I made my knfsd package available only because I use it and noone else
seems to maintain it. But I don't have much time to really work on it.
I will only fix bugs in the NFS utilities and serious kernel NFS bugs
which I can duplcate easily. If you have any kernel NFS server problem,
please report it to the Linux kernel mailing list. If it can be
reproduced with Linux NFS server and client in less than 5 minutes, you
can also send me a copy in addition to sending it to the Linux kernel
mailing list. I may take a look when I have time. However I will collect
kernel NFS related patches. Contributions are more than welcome.

The NFS lock only works with lockd. Please make sure the portmapper,
portmap, is started before mounting NFS.

Changes from knfsd 1.4.6:

1. Fix a typo in knfslock.init.
2. A new kernel patch, nfsd-2.2.7-1.lock.patch, to fix some NFS lock
   bugs.

Changes from knfsd 1.4.5:

1. Rename /var/lib/nfs/xtab.export to /var/lib/nfs/etab.

Changes from knfsd 1.4.4:

1. Try to fix mountd performance problem by introducing
   /var/lib/nfs/xtab.export. That is
   
  a. "exportfs" reads from /var/lib/nfs/xtab and writes to
     /var/lib/nfs/xtab.export.
  b. "mountd" reads from /var/lib/nfs/xtab.export and writes to
     /var/lib/nfs/xtab.

  The idea is "mountd" doesn't have to read /var/lib/nfs/xtab, which
  is very expensive.

Changes from knfsd 1.4.3:

1. nfsd-2.2.7-nfsfh.patch, a new kernel patch for filehandle.

You have to apply the patch, locks-2.2.3.diff, to the Linux kernel
first. It fixes quite some file lock bugs. That patch is against Linux
2.2.3. If your kernel is different, you have to apply it by hand.

nfsd-2.2.3-1.patch is a new knfsd patch against linux 2.2.3 from
"G. Allen Morris III" (gam3@acm.org). It works for me on x86 and alpha.
It is needed for the none-Linux NFS clients. You can get Allen's
current patch from

http://www.CSUA.Berkeley.EDU/~gam3/knfsd/

nfsd-2.2.7-3.patch is based on nfsd-2.2.3-1.patch for Linux 2.2.7. If
you use Linux 2.2.7, you should apply nfsd-2.2.7-3.patch instead of
nfsd-2.2.3-1.patch. Please don't use any other patches included here
for Linux 2.2.7. For other kernel versions, you may have to apply it
by hand.

nfsd-2.2.7-2.lockd.patch is also necessary to start lockd independent
of nfs and nfsd.

To compile, just do

# ./configure
# make

Makefile will try to determine which C library you are using and compile
this package accordingly.

# make install

will install the knfsd binaries. You have to install a knfs start up
script by hand. There is a new rc.nfsd in etc. I use it for both the
user-space nfsd and the kernel nfsd.

There is one RPM spec file, knfs.spec, which is for a Linux system
based on Linux 2.2 without support for Linux 2.0. You also need
knfsd-1.4.6.tar.gz to create the knfsd RPMs.

Thanks.
