V7 Link: https://lore.kernel.org/linux-trace-devel/20210819041321.105110033@xxxxxxxxxxx/ Changes from v7: I moved the patches that have been acked by Masami into my linux-next queue and removed them from this patch series. I added Masami's patch to check for duplicate events and return a proper error message about the duplication. I changed the duplication check in the eprobe code to match Masami's changes. I fixed a bug in the removing of dynamic events in the selftest code. Added a new test to make sure the duplicate events are caught. Masami Hiramatsu (1): tracing/probes: Reject events which have the same name of existing one Steven Rostedt (VMware) (3): selftests/ftrace: Add clear_dynamic_events() to test cases selftests/ftrace: Add selftest for testing eprobe events selftests/ftrace: Add selftest for testing duplicate eprobes and kprobes Tzvetomir Stoyanov (VMware) (1): tracing: Add a probe that attaches to trace events ---- include/linux/trace_events.h | 4 + kernel/trace/Makefile | 1 + kernel/trace/trace.c | 5 +- kernel/trace/trace.h | 18 + kernel/trace/trace_eprobe.c | 903 +++++++++++++++++++++ kernel/trace/trace_events_trigger.c | 14 +- kernel/trace/trace_kprobe.c | 14 +- kernel/trace/trace_probe.c | 41 +- kernel/trace/trace_probe.h | 7 +- kernel/trace/trace_uprobe.c | 6 +- .../ftrace/test.d/dynevent/add_remove_eprobe.tc | 53 ++ .../ftrace/test.d/dynevent/test_duplicates.tc | 28 + tools/testing/selftests/ftrace/test.d/functions | 22 + 13 files changed, 1101 insertions(+), 15 deletions(-) create mode 100644 kernel/trace/trace_eprobe.c create mode 100644 tools/testing/selftests/ftrace/test.d/dynevent/add_remove_eprobe.tc create mode 100644 tools/testing/selftests/ftrace/test.d/dynevent/test_duplicates.tc
