NFSv4: Convert nfs41_free_stateid to use an asynchronous RPC call

2013-05-06T21:24:22+00:00

The main reason for doing this is will be to allow for an asynchronous
RPC mode that we can use for freeing lock stateids as per section
8.2.4 of RFC5661.

NFSv4: Record the OPEN create mode used in the nfs4_opendata structure

2013-04-16T22:58:26+00:00

If we're doing NFSv4.1 against a server that has persistent sessions,
then we should not need to call SETATTR in order to reset the file
attributes immediately after doing an exclusive create.

Note that since the create mode depends on the type of session that
has been negotiated with the server, we should not choose the
mode until after we've got a session slot.

SUNRPC: Define rpcsec_gss_info structure

2013-03-29T19:42:56+00:00

The NFSv4 SECINFO procedure returns a list of security flavors.  Any
GSS flavor also has a GSS tuple containing an OID, a quality-of-
protection value, and a service value, which specifies a particular
GSS pseudoflavor.

For simplicity and efficiency, I'd like to return each GSS tuple
from the NFSv4 SECINFO XDR decoder and pass it straight into the RPC
client.

Define a data structure that is visible to both the NFS client and
the RPC client.  Take structure and field names from the relevant
standards to avoid confusion.

NFS: Remove unneeded forward declaration

2013-03-29T19:42:39+00:00

I've built with NFSv4 enabled and disabled.  This forward
declaration does not seem to be required.

NFSv4: The stateid must remain the same for replayed RPC calls

2013-03-25T16:04:10+00:00

If we replay a READ or WRITE call, we should not be changing the
stateid. Currently, we may end up doing so, because the stateid
is only selected at xdr encode time.

This patch ensures that we select the stateid after we get an NFSv4.1
session slot, and that we keep that same stateid across retries.

NFSv4.1: LAYOUTGET EDELAY loops timeout to the MDS

2013-03-01T01:41:35+00:00

The client will currently try LAYOUTGETs forever if a server is returning
NFS4ERR_LAYOUTTRYLATER or NFS4ERR_RECALLCONFLICT - even if the client no
longer needs the layout (ie process killed, unmounted).

This patch uses the DS timeout value (module parameter 'dataserver_timeo'
via rpc layer) to set an upper limit of how long the client tries LATOUTGETs
in this situation.  Once the timeout is reached, IO is redirected to the MDS.

This also changes how the client checks if a layout is on the clp list
to avoid a double list_add.
