Package: nfs-user-server
Version: 2.2beta47-25
Severity: grave
Justification: causes non-serious data loss
There is a problem when one tries to replace an existing file using an
NFS client that is served by nfs-user-server: The replacement operation
fails with EINVAL on the client and on the server the file is replaced
with new contents of zero length. In order for this to happen
apparently one must first use that same client to create the file.
The problem apparently has been known about in ubuntu now for over 2
years with no action taken. There's a succinct scenario described in
their bug tracker for reproducing the problem. Please see here:
(subject: "nfs-user-server destroys files")
https://bugs.launchpad.net/ubuntu/+source/nfs-user-server/+bug/162508
Here's the scenario from that bug report:

You can reproduce this using bash:
root@hop:/s/tmp#
root@hop:/s/tmp#
root@hop:/s/tmp#
root@hop:/s/tmp# echo test >test.txt
root@hop:/s/tmp# cat test.txt
test
root@hop:/s/tmp# echo xyz >>test.txt
root@hop:/s/tmp# cat test.txt
test
xyz
root@hop:/s/tmp# echo abc >test.txt
bash: test.txt: Invalid argument
root@hop:/s/tmp# cat test.txt
root@hop:/s/tmp# ls -l test.txt
-rw------- 1 root root 0 2008-01-08 09:31 test.txt
root@hop:/s/tmp#
where /s is a nfs mount.

I have reproduced this behavior in Debian using the Debian-supplied
nfs-user-server version 2.2beta47-25. Guess everyone is using the
kernel mode server instead so nobody notices a problem as bad as this.
I was trying out this server however in an attempt to work around
another issue with the kernel mode server.
