This list does not include any non-GSS flavors that have been registered with the RPC client. nfs4_find_root_sec() currently adds these extra flavors by hand. Instead, nfs4_find_root_sec() should be looking at the set of flavors that have been explicitly registered via rpcauth_register(). And, other areas of code will soon need the same kind of list that contains all flavors the kernel currently knows about (see below). Rather than cloning the open-coded logic in nfs4_find_root_sec() to those new places, introduce a generic RPC function that generates a full list of registered auth flavors and pseudoflavors. A new rpc_authops method is added that lists a flavor's pseudoflavors, if it has any. I encountered an interesting module loader loop when I tried to get the RPC client to invoke gss_mech_list_pseudoflavors() by name. This patch is a pre-requisite for server trunking discovery, and a pre-requisite for fixing up the in-kernel mount client to do better automatic security flavor selection.
