Description

Both clnt_vc_control() and clnt_dg_control() could return RPC_FAILED instead of FALSE here:

876clnt_vc_control(CLIENT *cl, int request, char *info)
877{
878    bool_t ret;
879/* LINTED pointer alignment */
880    struct ct_data *ct = (struct ct_data *)cl->cl_private;
881
882    if (rpc_fd_lock(vctbl, ct->ct_fd)) {
883        rpc_fd_unlock(vctbl, ct->ct_fd);
884        return (RPC_FAILED);
885    }

711static bool_t
712clnt_dg_control(CLIENT *cl, int request, char *info)
713{
714/* LINTED pointer alignment */
715    struct cu_data *cu = (struct cu_data *)cl->cl_private;
716    struct netbuf *addr;
717    if (rpc_fd_lock(dgtbl, cu->cu_fd)) {
718        rpc_fd_unlock(dgtbl, cu->cu_fd);
719        return (RPC_FAILED);
720    }

Both clnt_vc_control() and clnt_dg_control() are internal implementation of clnt_control(3nsl). The clnt_control(3nsl) should return TRUE (success) or FALSE (failure).

The problem is that RPC_FAILED (with value 16) is returned here on failure. So the return value is both invalid and confusing.
