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:

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

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

2010-08-04T12:54:05+00:00

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...

NFSv4: Reintroduce machine creds

2008-04-19T20:54:56+00:00

We need to try to ensure that we always use the same credentials whenever
we re-establish the clientid on the server. If not, the server won't
recognise that we're the same client, and so may not allow us to recover
state.

NFSv4: Don't use cred->cr_ops->cr_name in nfs4_proc_setclientid()

2008-04-19T20:54:53+00:00

With the recent change to generic creds, we can no longer use
cred->cr_ops->cr_name to distinguish between RPCSEC_GSS principals and
AUTH_SYS/AUTH_NULL identities. Replace it with the rpc_authops->au_name
instead...
