From 97f68c6b02e0225b38d327103c59cfe2ab5ecda7 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 3 Dec 2018 11:30:30 +1100 Subject: SUNRPC: add 'struct cred *' to auth_cred and rpc_cred The SUNRPC credential framework was put together before Linux has 'struct cred'. Now that we have it, it makes sense to use it. This first step just includes a suitable 'struct cred *' pointer in every 'struct auth_cred' and almost every 'struct rpc_cred'. The rpc_cred used for auth_null has a NULL 'struct cred *' as nothing else really makes sense. For rpc_cred, the pointer is reference counted. For auth_cred it isn't. struct auth_cred are either allocated on the stack, in which case the thread owns a reference to the auth, or are part of 'struct generic_cred' in which case gc_base owns the reference, and "acred" shares it.
