for kprobe session Signed-off-by: Jiri Olsa <[email protected]>
There are several maps used in all generic sensors, moving them into single generic_maps.h header. Signed-off-by: Jiri Olsa <[email protected]>
Using process_call_heap in generic functions directly, so we don't need to pass it as argument. Passing map pointer through argument might end up storing and loading it to/from heap which makes it scalar value and breaks verifier. Signed-off-by: Jiri Olsa <[email protected]>
Using config_map in generic functions directly, so we don't need to pass it as argument. Passing map pointer through argument might end up storing and loading it to/from heap which makes it scalar value and breaks verifier. Signed-off-by: Jiri Olsa <[email protected]>
Using data_heap in generic functions directly, so we don't need to pass it as argument. Passing map pointer through argument might end up storing and loading it to/from heap which makes it scalar value and breaks verifier. Signed-off-by: Jiri Olsa <[email protected]>
Moving generic_output to generic functions and change it to use process_call_heap in generic functions directly, so we don't need to pass it as argument. Passing map pointer through argument might end up storing and loading it to/from heap which makes it scalar value and breaks verifier. Signed-off-by: Jiri Olsa <[email protected]>
Moving generic_actions to generic functions, so we can use generic maps in it directly in following changes. Signed-off-by: Jiri Olsa <[email protected]>
Switching generic_actions to use maps directly. Passing map pointer through argument might end up storing and loading it to/from heap which makes it scalar value and breaks verifier. Keeping tail call map, because it's convenient in following changes. Signed-off-by: Jiri Olsa <[email protected]>
Adding generic_retkprobe function (from generic_retkprobe_event) and change it to use process_call_heap in generic functions directly, so we don't need to pass it as argument. Passing map pointer through argument might end up storing and loading it to/from heap which makes it scalar value and breaks verifier. Signed-off-by: Jiri Olsa <[email protected]>
Switching generic_start_process_filter to use maps directly and drop struct generic_maps. Keeping tail call map, because it's convenient in following changes. Signed-off-by: Jiri Olsa <[email protected]>
