From a52458b48af142bcc2b72fe810c0db20cfae7fdd Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.com> Date: Mon, 3 Dec 2018 11:30:31 +1100 Subject: NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'. 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 <neilb@suse.com> Acked-by: J.
