Clean up: The client side peer address is available in callback_proc.c, so move a dprintk out of fs/nfs/callback.c and into fs/nfs/callback_proc.c. This is more consistent with other debugging messages, and the proc routines have more information about each request to display.

To ensure the NFS client displays IPv6 addresses properly, replace address family-specific NIPQUAD() invocations with a call to the RPC client to get a formatted string representing the remote peer's address.

We recently added methods to RPC transports that provide string versions of the remote peer address information. Convert the NFSv4 SETCLIENTID procedure to use those methods instead of building the client ID out of whole cloth.

Ensure that the RPC buffer size specified for NFSv4 SETCLIENTID procedures matches what we are encoding into the buffer.

Universal addresses are defined in RFC 1833 and clarified in RFC 3530. We need to use them in several places in the NFS and RPC clients, so move the relevant definition and block comment to an appropriate global include file.

If the ULP doesn't pass a hostname string to rpc_create(), it manufactures one based on the passed-in address. Be smart enough to handle an AF_INET6 address properly in this case. Move the default servername logic before the xprt_create_transport() call to simplify error handling in rpc_create().

The address comparison in the __nfs_find_client() function is deceptive. It uses a memcmp() to check a pair of u32 fields for equality. Not only is this inefficient, but usually memcmp() is used for comparing two *whole* sockaddr_in's (which includes comparisons of the address family and port number), so it's easy to mistake the comparison here for a whole sockaddr comparison, which it isn't. So for clarity and efficiency, we replace the memcmp() with a simple test for equality between the two s_addr fields. This should have no behavioral effect.

Text-based mount option parsing introduced a minor regression in the behavior of NFS version 4 mounts. NFS version 4 is not supposed to require a running rpcbind service on the server in order for a mount to succeed. In other words, if the mount options don't specify a port number, the port number is supposed to default to 2049. For earlier versions of NFS, the default port number was zero in order to cause the RPC client to autobind to the server's NFS service.

POSIX requires that ctime and mtime, as reported by the stat(2) call, reflect the activity of the most recent write(2). To that end, nfs_getattr() flushes pending dirty writes to a file before doing a GETATTR to allow the NFS server to set the file's size, ctime, and mtime properly. However, nfs_getattr() can be starved when a constant stream of application writes to a file prevents nfs_wb_nocommit() from completing. This usually results in hangs of programs doing a stat against an NFS file that is being written. "ls -l" is a common victim of this behavior. To prevent starvation, hold the file's i_mutex in nfs_getattr() to freeze applications writes temporarily so the client can more quickly obtain clean values for a file's size, mtime, and ctime.

The nfs_wcc_update_inode() function omits logic to convert the type of the NFS on-the-wire value of a file's size (__u64) to the type of file size value stored in struct inode (loff_t, which is signed). Everywhere else in the NFS client I checked already correctly converts the file size type. This effects only very large files.
