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. 2. nfsd-2.2.7-2.lockd.patch, a new patch for lockd. 3. Misc bug fixes. Changes from knfsd 1.4.2: 1. A mountd patch so that the syslog reports unknown requests, and also reports *what* is being (un)mounted, from Piete Brooks . 2. Fix knfsd.init for restart. 3. Add knfslock.init. 4. knfsd-compat.spec is removed. 5. nfsd-2.2.7-lockd.patch, a patch to start lockd independent of nfs and nfsd. Changes from knfsd 1.4.1: 1. Resolve symlink for umount from Piete.Brooks@cl.cam.ac.uk (Piete Brooks) 2. Fix knfsd.init for statd. Changes from knfsd 1.4: 1. nfsd-2.2.7-3.patch.

Changes from knfsd 1.3a: 1. nfsd-2.2.8-1.patch. This is the only patch you need for Linux 2.2.8. 2. nfsd-2.2.7-2.patch. This is the only patch you need for Linux 2.2.7. Changes from knfsd 1.3: 1. Adding "--no-nfs-version 3" to mountd in knfsd.init from RedHat 6.0. Changes from knfsd 1.2.2a: 1. Updated knfsd.init from RedHat 6.0. 2. nfsd-2.2.7-1.patch.

It is available at ftp://ftp.varesearch.com/pub/support/hjl/knfsd/knfsd-1.4.7.tar.gz ftp://ftp.varesearch.com/pub/support/hjl/knfsd/knfsd-1.4.6-1.4.7.diff.gz ftp://ftp.kernel.org/pub/linux/devel/gcc/knfsd-1.4.7.tar.gz ftp://ftp.kernel.org/pub/linux/devel/gcc/knfsd-1.4.6-1.4.7.diff.gz 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.
