SUNRPC: replace program list with program array

2024-09-23T19:03:30Z

A service created with svc_create_pooled() can be given a linked list of programs and all of these will be served. Using a linked list makes it cumbersome when there are several programs that can be optionally selected with CONFIG settings. After this patch is applied, API consumers must use only svc_create_pooled() when creating an RPC service that listens for more than one RPC program.

SUNRPC: add svcauth_map_clnt_to_svc_cred_local

2024-09-23T19:03:30Z

Add new funtion svcauth_map_clnt_to_svc_cred_local which maps a generic cred to a svc_cred suitable for use in nfsd. This is needed by the localio code to map nfs client creds to nfs server credentials. Following from net/sunrpc/auth_unix.c:unx_marshal() it is clear that ->fsuid and ->fsgid must be used (rather than ->uid and ->gid). In addition, these uid and gid must be translated with from_kuid_munged() so local client uses correct uid and gid when acting as local server. Jeff Layton noted: This is where the magic happens. Since we're working in kuid_t/kgid_t, we don't need to worry about further idmapping.

SUNRPC: remove call_allocate() BUG_ONs

2024-09-23T19:03:30Z

Remove BUG_ON if p_arglen=0 to allow RPC with void arg. Remove BUG_ON if p_replen=0 to allow RPC with void return. The former was needed for the first revision of the LOCALIO protocol which had an RPC that took a void arg: /* raw RFC 9562 UUID */ typedef u8 uuid_t; program NFS_LOCALIO_PROGRAM { version LOCALIO_V1 { void NULL(void) = 0; uuid_t GETUUID(void) = 1; } = 1; } = 400122; The latter is needed for the final revision of the LOCALIO protocol which has a UUID_IS_LOCAL RPC which returns a void: /* raw RFC 9562 UUID */ typedef u8 uuid_t; program NFS_LOCALIO_PROGRAM { version LOCALIO_V1 { void NULL(void) = 0; void UUID_IS_LOCAL(uuid_t) = 1; } = 1; } = 400122; There is really no value in triggering a BUG_ON in response to either of these previously unsupported conditions. NeilBrown would like the entire 'if (proc->p_proc != 0)' branch removed (not just the one BUG_ON that must be removed for LOCALIO's immediate needs of returning void).

SUNRPC: clnt.c: Remove misleading comment

2024-09-23T19:03:13Z

destroy_wait doesn't store all RPC clients. There was a list named "all_clients" above it, which got moved to struct sunrpc_net in 2012, but the comment was never removed.
