SUNRPC: New xdr_streams XDR decoder API

2010-12-16T17:37:25+00:00

Now that all client-side XDR decoder routines use xdr_streams, there
should be no need to support the legacy calling sequence [rpc_rqst *,
__be32 *, RPC res *] anywhere.  We can construct an xdr_stream in the
generic RPC code, instead of in each decoder function.

This is a refactoring change.  It should not cause different behavior.

SUNRPC: New xdr_streams XDR encoder API

2010-12-16T17:37:25+00:00

Now that all client-side XDR encoder routines use xdr_streams, there
should be no need to support the legacy calling sequence [rpc_rqst *,
__be32 *, RPC arg *] anywhere.  We can construct an xdr_stream in the
generic RPC code, instead of in each encoder function.

Also, all the client-side encoder functions return 0 now, making a
return value superfluous.  Take this opportunity to convert them to
return void instead.

This is a refactoring change.  It should not cause different behavior.

This actually causes a build failure on a sparc32 defconfig build:

`rpcauth_remove_module' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o

I applied the following patch for today:

Fixes:

SUNRPC: Move the bound cred to struct rpc_rqst

2010-08-04T12:54:09+00:00

This will allow us to save the original generic cred in rpc_message, so
that if we migrate from one server to another, we can generate a new bound
cred without having to punt back to the NFS layer.

SUNRPC: Make the credential cache hashtable size configurable

2010-08-04T12:54:06+00:00

This patch allows the user to configure the credential cache hashtable size
using a new module parameter: auth_hashtable_size
When set, this parameter will be rounded up to the nearest power of two,
with a maximum allowed value of 1024 elements.

SUNRPC: Store the hashtable size in struct rpc_cred_cache

Cleanup in preparation for allowing the user to determine the maximum hash
table size.

SUNRPC: Don't spam gssd with upcall requests when the kerberos key expired

2010-05-14T19:09:37+00:00

Now that the rpc.gssd daemon can explicitly tell us that the key expired,
we should cache that information to avoid spamming gssd.

SUNRPC: Defer the auth_gss upcall when the RPC call is asynchronous

2009-09-16T00:49:33+00:00

Otherwise, the upcall is going to be synchronous, which may not be what the
caller wants...
