Allow RPC client transport implementations to be loaded as needed, or as they become available from distributors or third-party vendors. Note that we leave the IP sockets implementation in sunrpc.o permanently, as IP functionality is always available in any kernel that runs NFS.

Adds a flag word to the xdrbuf struct which indicates any bulk disposition of the data.

The previous patch introduced a bug when copying the server address. Also clarify a copy into the auth_flavours array: currently the two size calculations are equivalent, but we may decide to change the size of auth_flavors[] at some point.

I got the 'mounthost=' option wrong - it shouldn't look for an address value, but rather a hostname value. However, the in-kernel mount client and NFS client cannot resolve a hostname by themselves; they rely on user-land to pass in the resolved address. Create a new mount option that does take an address so that the mount program's address can be passed in. The mount hostname is now ignored by the kernel.

If no mount server port number is specified, the previous change to the kernel mount client inadvertently allows the NFS server's port number to be the used as the mount server's port number. If the user specifies an NFS server port (-o port=x), the mount will fail. The fix below sets the mount server's port to 0 if no mount server port is specified by the user.

The purpose of an RPC ping (a NULL request) is to determine whether the remote end is operating and supports the RPC program and version of the request. If we do an RPC bind and the remote's rpcbind service says "this program or service isn't supported" then we have our answer already, and we should give up immediately. This is good for the kernel mount client, as it will cause the request to fail, and then allow an immediate retry with different options.

Add more new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns EACCES) Case 2: retry with a lesser rpcbind version (rpcb now returns EPFNOSUPPORT) This change allows more specific error processing for each of these two cases. We now fail case 2 instead of retrying... it's a server configuration error not to support even rpcbind version 2. And don't expose this new error code to user land -- convert it to EIO before failing the RPC.

Add new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns -EACCES) Case 2: another process is already in the middle of binding on this transport (now returns -EAGAIN) This change allows more specific retry processing for each of these two cases.

Noticed by Tom Talpey <tmt@netapp.com>: OBTW, there's a nit on that memcpy, too. The r_addr is an array, so memcpy(&map->r_addr is passing the address of the array as a char **.

Fix some problems with rpcbind v3 and v4 queries from the in-kernel rpcbind client: 1. The r_addr argument must be a full universal address, not just an IP address, and 2. The universal address in r_addr is the address of the remote rpcbind server, not the RPC service being requested This addresses bugzilla.kernel.org report 8891 for 2.6.23-rc and greater. In addition, if the rpcbind client is unable to start the rpcbind request, make sure not to leak the xprt. Signed-off-by: NChuck Lever <chuck.lever@oracle.com>
