NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'.

2018-12-19T18:52:46+00:00

SUNRPC has two sorts of credentials, both of which appear as
"struct rpc_cred".
There are "generic credentials" which are supplied by clients
such as NFS and passed in 'struct rpc_message' to indicate
which user should be used to authorize the request, and there
are low-level credentials such as AUTH_NULL, AUTH_UNIX, AUTH_GSS
which describe the credential to be sent over the wires.

This patch replaces all the generic credentials by 'struct cred'
pointers - the credential structure used throughout Linux.

For machine credentials, there is a special 'struct cred *' pointer
which is statically allocated and recognized where needed as
having a special meaning.  A look-up of a low-level cred will
map this to a machine credential.

NFS: Pass the inode down to the getattr() callback

2018-06-04T16:07:07+00:00

Allow the getattr() callback to check things like whether or not we hold
a delegation so that it can adjust the attributes that it is asking for.

NFSv4: Fix sillyrename to return the delegation when appropriate

2018-05-31T19:02:16+00:00

Ensure that we pass down the inode of the file being deleted so
that we can return any delegation being held.

NFS: Move call to nfs4_state_protect() to nfs4_commit_setup()

2018-05-31T19:02:16+00:00

Rather than doing this in the generic NFS client code.  Let's put this
with the other v4 stuff so it's all in one place.

NFS: Move call to nfs4_state_protect_write() to nfs4_write_setup()

2018-05-31T19:02:16+00:00

This doesn't really need to be in the generic NFS client code, and I
think it makes more sense to keep the v4 code in one place.
