The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.Signed-off-by: Eric W. Biederman

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).Signed-off-by: Tim Schmielau

Expand the rq_addr field to allow it to contain larger addresses.
Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then
everywhere the 'sockaddr_in' was referenced, we use instead an accessor
function (svc_addr_in) which safely casts the _storage to _in.Signed-off-by: Chuck Lever

There are loads of places where the RPC server assumes that the rq_addr fields
contains an IPv4 address. Top among these are error and debugging messages
that display the server's IP address.Let's refactor the address printing into a separate function that's smart
enough to figure out the difference between IPv4 and IPv6 addresses.Signed-off-by: Chuck Lever

Sometimes we need to create an RPC service but not register it with the local
portmapper. NFSv4 delegation callback, for example.Change the svc_makesock() API to allow optionally creating temporary or
permanent sockets, optionally registering with the local portmapper, and make
it return the ephemeral port of the new socket.Signed-off-by: Chuck Lever

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

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

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 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
