SUNRPC: Ensure client closes the socket when server initiates a close
If the server decides to close the RPC socket, we currently don't actually
respond until either another RPC call is scheduled, or until xprt_autoclose()
gets called by the socket expiry timer (which may be up to 5 minutes
later).
This patch ensures that xprt_autoclose() is called much sooner if the
server closes the socket.

SUNRPC: transport switch API for setting port number
At some point, transport endpoint addresses will no longer be IPv4. To hide
the structure of the rpc_xprt's address field from ULPs and port mappers,
add an API for setting the port number during an RPC bind operation.
Test-plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.
Probably need to rig a server where certain services aren't running, or
that returns an error for some typical operation.

SUNRPC: switchable buffer allocation
Add RPC client transport switch support for replacing buffer management
on a per-transport basis.
In the current IPv4 socket transport implementation, RPC buffers are
allocated as needed for each RPC message that is sent. Some transport
implementations may choose to use pre-allocated buffers for encoding,
sending, receiving, and unmarshalling RPC messages, however. For
transports capable of direct data placement, the buffers can be carved
out of a pre-registered area of memory rather than from a slab cache.
Test-plan:
Millions of fsx operations. Performance characterization with "sio" and
"iozone". Use oprofile and other tools to look for significant regression
in CPU utilization.

NFSv3: try get_root user-supplied security_flavor
Thanks to Ed Keizer for bug and root cause. He says: "... we could only mount
the top-level Solaris share. We could not mount deeper into the tree.
Investigation showed that Solaris allows UNIX authenticated FSINFO only on the
top level of the share. This is a problem because we share/export our home
directories one level higher than we mount them. I.e. we share the partition
and not the individual home directories. This prevented access to home
directories."
We still may need to try auth_sys for the case where the client doesn't have
appropriate credentials.

NLM: Further cancel fixes
If the server receives an NLM cancel call and finds no waiting lock to
cancel, then chances are the lock has already been applied, and the client
just hadn't yet processed the NLM granted callback before it sent the
cancel.
The Open Group text, for example, perimts a server to return either success
(LCK_GRANTED) or failure (LCK_DENIED) in this case. But returning an error
seems more helpful; the client may be able to use it to recognize that a
race has occurred and to recover from the race.
So, modify the relevant functions to return an error in this case.

NLM: don't unlock on cancel requests
Currently when lockd gets an NLM_CANCEL request, it also does an unlock for
the same range. This is incorrect.
The Open Group documentation says that "This procedure cancels an
*outstanding* blocked lock request." (Emphasis mine.)
Also, consider a client that holds a lock on the first byte of a file, and
requests a lock on the entire file. If the client cancels that request
(perhaps because the requesting process is signalled), the server shouldn't
apply perform an unlock on the entire file, since that will also remove the
previous lock that the client was already granted.
Or consider a lock request that actually *downgraded* an exclusive lock to
a shared lock.

According to RFC3530 we're supposed to cache the change attribute

If the inode is clean, a CB_GETATTR callback by the server to the
client is supposed to return the cached change attribute.
If, OTOH, the inode is dirty, the client should bump the cached
change attribute by 1.

NFS: support large reads and writes on the wire
Most NFS server implementations allow up to 64KB reads and writes on the
wire. The Solaris NFS server allows up to a megabyte, for instance.
Now the Linux NFS client supports transfer sizes up to 1MB, too. This will
help reduce protocol and context switch overhead on read/write intensive NFS
workloads, and support larger atomic read and write operations on servers
that support them.

NFS: use generic_write_checks() to sanity check direct writes
Replace ad hoc write parameter sanity checking in nfs_file_direct_write()
with a call to generic_write_checks(). This should make the proper checks
modulo the O_LARGEFILE flag, and should catch NFSv2-specific limitations by
virtue of i_sb->s_maxbytes.
Test plan:
Posix compliance testing with both NFSv2 and NFSv3.

NFSv4: Remove requirement for machine creds for the "renew" operation
In RFC3530, the RENEW operation is allowed to use either
the same principal, RPC security flavour and (if RPCSEC_GSS), the same
mechanism and service that was used for SETCLIENTID_CONFIRM
OR
Any principal, RPC security flavour and service combination that
currently has an OPEN file on the server.
Choose the latter since that doesn't require us to keep credentials for
the same principal for the entire duration of the mount.

NFSv4: Make nfs4_state track O_RDWR, O_RDONLY and O_WRONLY separately
A closer reading of RFC3530 reveals that OPEN_DOWNGRADE must always
specify a access modes that have been the argument of a previous OPEN
operation.
IOW: doing OPEN(O_RDWR) and then OPEN_DOWNGRADE(O_WRONLY) is forbidden
unless the user called OPEN(O_WRONLY)
In order to fix that, we really need to track the three possible open
states separately.

NFSv4: stateful NFSv4 RPC call interface
The NFSv4 model requires us to complete all RPC calls that might
establish state on the server whether or not the user wants to
interrupt it. We may also need to schedule new work (including
new RPC calls) in order to cancel the new state.
The asynchronous RPC model will allow us to ensure that RPC calls
always complete, but in order to allow for "synchronous" RPC, we
want to add the ability to wait for completion.
The waits are, of course, interruptible.

Shrink the RPC task structure. Instead of storing separate pointers

Also pass the user data pointer as a parameter instead of passing it via
task->tk_calldata. This enables us to nest callbacks.

identify multipage ->writepages() calls
NFS needs to be able to distinguish between single-page ->writepage() calls and
multipage ->writepages() calls.
For the single-page writepage calls NFS can kick off the I/O within the
context of ->writepage().
For multipage ->writepages calls, nfs_writepage() will leave the I/O pending
and nfs_writepages() will kick off the I/O when it all has been queued up
within NFS.
