![]() This patch fixes a regression on setting up asynchronous commands to use external trigger sources when board-specific routing information is missing. `ni_find_device_routes()` (called via `ni_assign_device_routes()`) finds the table of register values for the device family and the set of valid routes for the specific board. If both are found, `tables->route_values` is set to point to the table of register values for the device family and `tables->valid_routes` is set to point to the list of valid routes for the specific board. If either is not found, both `tables->route_values` and `tables->valid_routes` are left set at their initial null values (initialized by `ni_assign_device_routes()`) and the function returns `-ENODATA`. Returning an error results in some routing functionality being disabled. Unfortunately, leaving `table->route_values` set to `NULL` also breaks the setting up of asynchronous commands that are configured to use external trigger sources. Calls to `ni_check_trigger_arg()` or `ni_check_trigger_arg_roffs()` while checking the asynchronous command set-up would result in a null pointer dereference if `table->route_values` is `NULL`. The null pointer dereference is fixed in another patch, but it now results in failure to set up the asynchronous command. That is a regression from the behavior prior to commit |
