Run this:
#!/bin/sh
for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
echo "De-casting $f..."
perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
doneAnd then go through and reinstate those cases where code is casting pointers
to non-pointers.And then drop a few hunks which conflicted with outstanding work.

It is possible for the ->fopen callback from lockd into nfsd to find that an
answer cannot be given straight away (an upcall is needed) and so the request
has to be 'dropped', to be retried later. That error status is not currently
propagated back.So:
Change nlm_fopen to return nlm error codes (rather than a private
protocol) and define a new nlm_drop_reply code.
Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply
when this error comes back.
Cause svc_process to drop a request which returns a status of
rpc_drop_reply.[akpm@osdl.org: fix warning storm]

When an nfs server shuts down, lockd needs to release all the locks even
though the client still holds them.It should therefore not 'unmonitor' the clients, so that the files in nfs/sm
will still be there when the nfs server restarts, so that those clients will
be told to reclaim their locks.However the hosts are fully unmonitored, so statd may well remove the files.
lockd has a test for 'sm_sticky' and avoid the unmonitor call if it is set,
but it is currently not set.So set it when tearing down lockd.

Every NLM call includes the client's NSM state. Currently, the Linux client
always reports 0 - which seems not to cause any problems, but is not what the
protocol says.This patch exposes the kernel's internal variable to user space via a sysctl,
which can be set at system boot time by statd.Signed-off-by: Olaf Kirch

When we send a GRANTED_MSG call, we current copy the NLM cookie provided in
the original LOCK call - because in 1996, some broken clients seemed to rely
on this bug. However, this means the cookies are not unique, so that when the
client's GRANTED_RES message comes back, we cannot simply match it based on
the cookie, but have to use the client's IP address in addition. Which breaks
when you have a multi-homed NFS client.The X/Open spec explicitly mentions that clients should not expect the same
cookie; so one may hope that any clients that were broken in 1996 have either
been fixed or rendered obsolete.Signed-off-by: Olaf Kirch

This patch adds the nsm_use_hostnames sysctl and module param. If set, lockd
will use the client's name (as given in the NLM arguments) to find the NSM
handle. This makes recovery work when the NFS peer is multi-homed, and the
reboot notification arrives from a different IP than the original lock calls.Signed-off-by: Olaf Kirch

As a result of previous patches, the loop in nlmsvc_invalidate_all just sets
h_expires for all client/hosts to 0 (though does it in a very complicated
way).This was possibly meant to trigger early garbage collection but half the time
'0' is in the future and so it infact delays garbage collection.Pre-aging the 'hosts' is not really needed at this point anyway so we throw
out the loop and nlm_find_client which is no longer needed.Signed-off-by: Neil Brown

This patch makes nlm_traverse{locks,blocks,shares} and friends use a function
pointer rather than a "action" enum.This function pointer is given two nlm_hosts (one given by the caller, the
other taken from the lock/block/share currently visited), and is free to do
with them as it wants. If it returns a non-zero value, the lockd/block/share
is released.Signed-off-by: Olaf Kirch

This patch makes the SM_NOTIFY handling understand and use the nsm_handle.
To make it a bit clear what is happening:
nlmclent_prepare_reclaim and nlmclnt_finish_reclaim
get open-coded into 'reclaimer'The result is tidied up.
Then some of that functionality is moved out into nlm_host_rebooted (which
calls nlmclnt_recovery which starts a thread which runs reclaimer).Also host_rebooted now finds an nsm_handle rather than a host, then then
iterates over all hosts and deals with each host that shares that nsm_handle.Signed-off-by: Olaf Kirch

This patch introduces the nsm_handle, which is shared by all nlm_host objects
referring to the same client.With this patch applied, all nlm_hosts from the same address will share the
same nsm_handle. A future patch will add sharing by name.Note: this patch changes h_name so that it is no longer guaranteed to be an IP
address of the host. When the host represents an NFS server, h_name will be
the name passed in the mount call. When the host represents a client, h_name
will be the name presented in the lock request received from the client. A
h_name is only used for printing informational messages, this change should
not be significant.Signed-off-by: Olaf Kirch

If lockd_up fails - what should we expect? Do we have to later call
lockd_down?Well the nfs client thinks "no", the nfs server thinks "yes". lockd thinks
"yes".The only answer that really makes sense is "no" !!
So:
Make lockd_up only increment nlmsvc_users on success.
Make nfsd handle errors from lockd_up properly.
Make sure lockd_up(0) never fails when lockd is running
so that the 'reclaimer' call to lockd_up doesn't need to
be error checked.Cc: "J. Bruce Fields"

Currently lockd listens on UDP always, and TCP if CONFIG_NFSD_TCP is set.
However as lockd performs services of the client as well, this is a problem.
If CONFIG_NfSD_TCP is not set, and a tcp mount is used, the server will not be
able to call back to lockd.So:
- add an option to lockd_up saying which protocol is needed
- Always open sockets for which an explicit port was given, otherwise
only open a socket of the type required
- Change nfsd to do one lockd_up per socket rather than one per thread.This
- removes the dependancy on CONFIG_NFSD_TCP
- means that lockd may open sockets other than at startup
- means that lockd will *not* listen on UDP if the only
mounts are TCP mount (and nfsd hasn't started).The latter is the only one that concerns me at all - I don't know if this
might be a problem with some servers.Signed-off-by: Neil Brown
