SUNRPC: Add a helper rpcauth_lookup_generic_cred()

2008-03-14T17:42:49+00:00

The NFSv4 protocol allows clients to negotiate security protocols on the fly in the case where an administrator on the server changes the export settings and/or in the case where we may have a filesystem migration event. Instead of having the NFS client code cache credentials that are tied to a particular AUTH method it is therefore preferable to have a generic credential that can be converted into whatever AUTH is in use by the RPC client when the read/write/sillyrename/... is put on the wire. We do this by means of the new "generic" credential, which basically just caches the minimal information that is needed to look up an RPCSEC_GSS, AUTH_SYS, or AUTH_NULL credential.

SUNRPC: Add an rpc_credop callback for binding a credential to an rpc_task

2008-03-14T17:42:41+00:00

We need the ability to treat 'generic' creds specially, since they want to bind instances of the auth cred instead of binding themselves. Signed-off-by: Trond Myklebust

SUNRPC: Add a generic RPC credential

2008-03-14T17:42:38+00:00

Add an rpc credential that is not tied to any particular auth mechanism, but that can be cached by NFS, and later used to look up a cred for whichever auth mechanism that turns out to be valid when the RPC call is being made. Signed-off-by: Trond Myklebust

SUNRPC: Clean up rpcauth_bindcred()

SUNRPC: Fix RPCAUTH_LOOKUP_ROOTCREDS

2008-03-14T17:42:32+00:00

The current RPCAUTH_LOOKUP_ROOTCREDS flag only works for AUTH_SYS authentication, and then only as a special case in the code. This patch removes the auth_sys special casing, and replaces it with generic code. Signed-off-by: Trond Myklebust

SUNRPC: Fix a bug in rpcauth_lookup_credcache()

2008-03-14T17:42:29+00:00

The hash bucket is for some reason always being set to zero. Signed-off-by: Trond Myklebust

SUNRPC: Mask signals across the call to rpc_call_setup() in rpc_run_task

2008-01-30T07:05:31+00:00

To ensure that the RPCSEC_GSS upcall is performed with the correct sigmask. Signed-off-by: Trond Myklebust

SUNRPC: Restrict sunrpc client exports

2008-01-30T07:05:28+00:00

The sunrpc client exports are not meant to be part of any official kernel API: they can change at the drop of a hat. Mark them as internal functions using EXPORT_SYMBOL_GPL. Signed-off-by: Trond Myklebust
