1/ decode_sattr and decode_sattr3 never return NULL, so remove
several checks for that. ditto for xdr_decode_hyper.
2/ replace some open coded XDR_QUADLEN calls with calls to
XDR_QUADLEN
3/ in decode_writeargs, simply an 'if' to use a single
calculation.
.page_len is the length of that part of the packet that did
not fit in the first page (the head).
So the length of the data part is the remainder of the
head, plus page_len.
3/ other minor cleanups.

When the kernel calls svc_reserve to downsize the expected size of an RPC
reply, it fails to account for the possibility of a checksum at the end of
the packet. If a client mounts a NFSv2/3 with sec=krb5i/p, and does I/O
then you'll generally see messages similar to this in the server's ring
buffer:
RPC request reserved 164 but used 208
While I was never able to verify it, I suspect that this problem is also
the root cause of some oopses I've seen under these conditions:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227726
This is probably also a problem for other sec= types and for NFSv4. The
large reserved size for NFSv4 compound packets seems to generally paper
over the problem, however.
This patch adds a wrapper for svc_reserve that accounts for the possibility
of a checksum. It also fixes up the appropriate callers of svc_reserve to
call the wrapper. For now, it just uses a hardcoded value that I
determined via testing. That value may need to be revised upward as things
change, or we may want to eventually add a new auth_op that attempts to
calculate this somehow.
Unfortunately, there doesn't seem to be a good way to reliably determine
the expected checksum length prior to actually calculating it, particularly
with schemes like spkm3.

The NFSv2 and NFSv3 servers do not handle WRITE requests for 0 bytes
correctly. The specifications indicate that the server should accept the
request, but it should mostly turn into a no-op. Currently, the server
will return an XDR decode error, which it should not.
Attached is a patch which addresses this issue. It also adds some boundary
checking to ensure that the request contains as much data as was requested
to be written. It also correctly handles an NFSv3 request which requests
to write more data than the server has stated that it is prepared to
handle. Previously, there was some support which looked like it should
work, but wasn't quite right.

Convert NFSv4 to the new lock interface. We don't define any callback for now,
so we're not taking advantage of the asynchronous feature--that's less critical
for the multi-threaded nfsd then it is for the single-threaded lockd. But this
does allow a cluster filesystems to export cluster-coherent locking to NFS.
Note that it's cluster filesystems that are the issue--of the filesystems that
define lock methods (nfs, cifs, etc.), most are not exportable by nfsd.

The nfsv4 protocol's lock operation, in the case of a conflict, returns
information about the conflicting lock.
It's unclear how clients can use this, so for now we're not going so far as to
add a filesystem method that can return a conflicting lock, but we may as well
return something in the local case when it's easy to.

The RPC buffer size estimation logic in net/sunrpc/clnt.c always
significantly overestimates the requirements for the buffer size.
A little instrumentation demonstrated that in fact rpc_malloc was never
allocating the buffer from the mempool, but almost always called kmalloc.
To compute the size of the RPC buffer more precisely, split p_bufsiz into
two fields; one for the argument size, and one for the result size.
Then, compute the sum of the exact call and reply header sizes, and split
the RPC buffer precisely between the two. That should keep almost all RPC
buffers within the 2KiB buffer mempool limit.
And, we can finally be rid of RPC_SLACK_SPACE!

We're inserting deny's between some ACEs in order to enforce posix draft acl
semantics which prevent permissions from accumulating across entries in an
acl.
That's fine, but we're doing that by inserting a deny after *every* allow,
which is overkill. We shouldn't be adding them in places where they actually
make no difference.
Also replaced some helper functions for creating acl entries; I prefer just
assigning directly to the struct fields--it takes a few more lines, but the
field names provide some documentation that I think makes the result easier

The rfc allows us to be more permissive about the ACL inheritance bits we
accept:
"If the server supports a single "inherit ACE" flag that applies to
both files and directories, the server may reject the request
(i.e., requiring the client to set both the file and directory
inheritance flags). The server may also accept the request and
silently turn on the ACE4_DIRECTORY_INHERIT_ACE flag."
Let's take the latter option--the ACL is a complex attribute that could be
rejected for a wide variety of reasons, and the protocol gives us little
ability to explain the reason for the rejection, so erroring out is a
user-unfriendly last resort.

The server name is expected to be a null-terminated string, so we can't pass
in the raw client identifier.
What's more, the client identifier is just a binary, not necessarily
printable, blob. Let's just use the ip address instead. The server name
appears to exist just to help debugging by making some printk's more

Note that the string is copies into the rpc client structure, so the pointer
to the local variable does not outlive the function call.

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).

Add support for using a filesystem UUID to identify and export point in the
filehandle.
For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up
too much room. For NFSv3+, we use the full 16 bytes, and possibly also a
64bit inode number for exports beneath the root of a filesystem.
When generating an fsid to return in 'stat' information, use the UUID (hashed
down to size) if it is available and a small 'fsid' was not specifically
provided.

filehandle
If we are using the same version/fsid as a current filehandle, then there is
no need to verify the the numbers are valid for this export, and they must be
(we used them to find this export).
This allows us to simplify the fsid selection code.
Also change "ref_fh_version" and "ref_fh_fsid_type" to "version" and
"fsid_type", as the important thing isn't that they are the version/type of
the reference filehandle, but they are the chosen type for the new filehandle.

Most files in the 'nfsd' filesystem are transactional. When you write, a
reply is generated that can be read back only on the same 'file'.
If the reply has zero length, the 'write' will incorrectly return a value of
'0' instead of the length that was written. This causes 'rpc.nfsd' to give an
annoying warning.

nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except
that the first pointer is 'struct readdir_cd *' rather than 'void *'. It
then casts encode_dent_fn points to 'filldir_t' as needed. This hides any
other type mismatches between the two such as the fact that the 'ino' arg
recently changed from ino_t to u64.
So: get rid of 'encode_dent_fn', get rid of the cast of the function type,
change the first arg of various functions from 'struct readdir_cd *' to
'void *', and live with the fact that we have a little less type checking
on the calling of these functions now. Less internal (to nfsd) checking
offset by more external checking, which is more important.

NFS V3 (and V4) support exclusive create by passing a 'cookie' which can get
stored with the file. If the file exists but has exactly the right cookie
stored, then we assume this is a retransmit and the exclusive create was
successful.
The cookie is 64bits and is traditionally stored in the mtime and atime
fields. This causes a problem with Solaris7 as negative mtime or atime
confuse it. So we moved two bits into the mode word instead.
But inherited ACLs sometimes overwrite the mode word on create, so this is a
problem.
So we give up and just store 62 of the 64 bits and assume that is close
enough.

NFSd assumes that largest number of pages that will be needed for a
request+response is 2+N where N pages is the size of the largest permitted
read/write request. The '2' are 1 for the non-data part of the request, and 1
for the non-data part of the reply.
However, when a read request is not page-aligned, and we choose to use
->sendfile to send it directly from the page cache, we may need N+1 pages to
hold the whole reply. This can overflow and array and cause an Oops.
This patch increases size of the array for holding pages by one and makes sure
that entry is NULL when it is not in use.

Pass the saved and current filehandles together into all the nfsd4 compound
operations.
I want a unified interface to these operations so we can just call them by

Also I'll eventually want a structure like this--that holds the state used
during compound processing--for deferral.
