perf events parse: Use just one parse events state struct

2017-11-26T13:50:20Z

commit d17d0878f456c8227345b6c76b918ec068fa0abd upstream. Andi reported problems when parse errors were detected with vendor events (json), because in the yyparse/parse_events_parse function we dereferenced the _data parameter to two different structs, with different layouts, which ended up making parse_events_evlist->error to point to random stack addresses. Fix it by making _data to always be struct parse_events_state, changing the only place where 'struct parse_events_term' was used in parse_events.y.

perf events parse: Rename parsing state struct to clearer name

2017-11-26T13:50:20Z

commit 5d369a75eda5855d64981668a1d60cfac00d52e9 upstream. Rename it from 'parse_events_evlist' to 'parse_events_state' to better state that this is parsing state that has to be passed around.

tools: Consolidate types.h

2014-05-01T19:22:39Z

Combine all definitions into a common tools/include/linux/types.h and kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper bitmap.h header.

perf parse events: Demystify memory allocations

2013-07-12T16:52:05Z

List heads are currently allocated way down the function chain in __add_event and add_tracepoint and then freed when the scanner code calls parse_events_update_lists. Be more explicit with where memory is allocated and who should free it. With this patch the list_head is allocated in the scanner code and freed when the scanner code calls parse_events_update_lists.

perf util: Use evsel->name to get tracepoint_paths

2013-07-12T16:46:02Z

Most tracepoint events already have their system and event name in ->name field so that searching whole event tracing directory for each evsel to match given id is suboptimal. Factor out this routine into tracepoint_name_to_path(). In case of en invalid name, it'll try to find path using id again.

perf tools: Keep group information

2013-01-31T16:07:43Z

Add a few of group-related field in struct perf_{evlist,evsel} so that the group information in a evlist can be known easily. It only counts groups which have more than 1 members since leader-only groups are treated as non-group events.

perf tools: Fix usage of __ in event parsing struct names

2013-01-24T19:40:51Z

In tools/perf we use a convention where __ separates the struct name from the function name for functions that operate on a struct instance. Fix this usage by removing it from the struct names and fix also the associated functions.
