Use __fpurge to ensure single-line writes to cache files

an error (which it can in normal operation, since it currently
(incorrectly) returns -ENOENT on any negative downcall), then subsequent
downcalls will write multiple lines (including the original line that
received the error).

refers to an unexported mount point (such as a readdir of a directory
containing such a mountpoint), so client commands hang.

Fix umount.nfs exit status

Hi,

As per a bug report from a user:

mount.c seems to assume that nfsumount() uses standard C true/false
return values, and inverts them for the exit status (where 0 is
traditionally considered success). However, nfsumount() consistently
seems to use 0 for success, and thus a success gets returned as exit
status 1 and a failure as exit status 0. This confuses at least
the GNOME drive manager applet, and probably others as well.

mount.nfs: Add the mount option "nosharecache"

Prior to David Howell's mount changes in 2.6.18, users who mounted
different directories which happened to be from the same filesystem on the
server would get different super blocks, and hence could choose different
mount options. As long as there were no hard linked files that crossed from
one subtree to another, this was quite safe.
Post the changes, if the two directories are on the same filesystem (have
the same 'fsid'), they will share the same super block, and hence the same
mount options.

Add a flag to allow users to elect not to share the NFS super block with
another mount point, even if the fsids are the same. This will allow
users to set different mount options for the two different super blocks, as
was previously possible. It is still up to the user to ensure that there
are no cache coherency issues when doing this, however the default
behaviour will be to share super blocks whenever two paths result in
the same fsid.

Add start-statd script.

This script is used by mount.nfs to run statd if needed.
It can be locally modified to change arguements if required.

If system-installed rpcgen if such exists.
If none is found, build our own.
Override with
   ./configure --with-rpcgen=internal
for internal rpcgen or
   ./configure --with-rpcgen=/local/rpcgen
for a non-standard location.

13 years agostatd - use dnsname to ensure correct matching of NOTIFY requests.
Neil Brown [Thu, 29 Mar 2007 03:08:08 +0000 (13:08 +1000)]
statd - use dnsname to ensure correct matching of NOTIFY requests.

When lockd asks to monitor a host, we find the FQDN from the DNS
and remember that, both internally and in the /var/lib/nfs/sm/*
file.
When we receive an SM_NOTIFY request, we compare both the
mon_name and the source IP address against that DNS name to find
a match.

If a DNS name is not available, we fall back to the name provided by
lockd, which at least is known to map to an IP address via
gethostbyname.

statd - check for 'priv' when looking for duplicate registrations.

From the point of view of the client (lockd), the 'priv' blob is probably
the most important key, so make sure to not throw away requests with
new 'priv' information.
