Modernize and harden the code path that parses an RPC Reply message. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Use struct xdr_stream when constructing RPC Call header

Modernize and harden the code path that constructs each RPC Call message. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Remove some dprintk() call sites from auth functions

2019-02-13T17:12:59Z

Clean up: Reduce dprintk noise by removing dprintk() call sites from hot path that do not report exceptions. These are usually replaceable with function graph tracing. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Add xdr_stream::rqst field

2019-02-13T16:05:50Z

Having access to the controlling rpc_rqst means a trace point in the XDR code can report: - the XID - the task ID and client ID - the p_name of RPC being processed Subsequent patches will introduce such trace points. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC discard cr_uid from struct rpc_cred.

2018-12-19T18:52:46Z

Just use ->cr_cred->fsuid directly. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

SUNRPC: simplify auth_unix.

2018-12-19T18:52:46Z

1/ discard 'struct unx_cred'. We don't need any data that is not already in 'struct rpc_cred'. 2/ Don't keep these creds in a hash table. When a credential is needed, simply allocate it. When not needed, discard it. This can easily be faster than performing a lookup on a shared hash table. As the lookup can happen during write-out, use a mempool to ensure forward progress. This means that we cannot compare two credentials for equality by comparing the pointers, but we never do that anyway. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

SUNRPC: remove crbind rpc_cred operation

2018-12-19T18:52:46Z

This now always just does get_rpccred(), so we don't need an operation pointer to know to do that. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

SUNRPC: remove generic cred code.

This is no longer used. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

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

2018-12-19T18:52:46Z

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. Signed-off-by: NeilBrown Acked-by: J. Bruce Fields Signed-off-by: Anna Schumaker
