tools lib traceevent: Fix processing of dereferenced args in bprintk events

2019-01-09T16:38:47+00:00

commit f024cf085c423bac7512479f45c34ee9a24af7ce upstream.

In the case that a bprintk event has a dereferenced pointer that is
stored as a string, and there's more values to process (more args), the
arg was not updated to point to the next arg after processing the
dereferenced pointer, and it screwed up what was to be displayed.

tools lib traceevent: Rename static variables and functions in event-parse.c

2018-08-13T18:37:26+00:00

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
static variables and functions in event-parse.c: pevent_func_params,
__pevent_parse_format, __pevent_parse_event, pevent_error_str, pevent_search_event
