hi, adding support to create multiple kprobes/uprobes within single perf event. This way we can associate single bpf program with multiple kprobes. Sending this as RFC because I'm not completely sure I haven't missed anything in the trace/events area. Also it needs following uprobe fix to work properly: https://lore.kernel.org/lkml/20211123142801.182530-1-jolsa@xxxxxxxxxx/ Also available at: https://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git bpf/kuprobe_batch thanks, jirka --- Jiri Olsa (8): perf/kprobe: Add support to create multiple probes perf/uprobe: Add support to create multiple probes libbpf: Add libbpf__kallsyms_parse function libbpf: Add struct perf_event_open_args libbpf: Add support to attach multiple [ku]probes libbpf: Add support for k[ret]probe.multi program section selftest/bpf: Add kprobe multi attach test selftest/bpf: Add uprobe multi attach test include/uapi/linux/perf_event.h | 1 + kernel/trace/trace_event_perf.c | 214 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++----------- kernel/trace/trace_kprobe.c | 47 ++++++++++++++++--- kernel/trace/trace_probe.c | 2 +- kernel/trace/trace_probe.h | 6 ++- kernel/trace/trace_uprobe.c | 43 +++++++++++++++-- tools/include/uapi/linux/perf_event.h | 1 + tools/lib/bpf/libbpf.c | 235 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-------------- tools/lib/bpf/libbpf.h | 25 +++++++++- tools/lib/bpf/libbpf_internal.h | 5 ++ tools/testing/selftests/bpf/prog_tests/multi_kprobe_test.c | 83 +++++++++++++++++++++++++++++++++ tools/testing/selftests/bpf/prog_tests/multi_uprobe_test.c | 97 ++++++++++++++++++++++++++++++++++++++ tools/testing/selftests/bpf/progs/multi_kprobe.c | 58 +++++++++++++++++++++++ tools/testing/selftests/bpf/progs/multi_uprobe.c | 26 +++++++++++ 14 files changed, 765 insertions(+), 78 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/multi_kprobe_test.c create mode 100644 tools/testing/selftests/bpf/prog_tests/multi_uprobe_test.c create mode 100644 tools/testing/selftests/bpf/progs/multi_kprobe.c create mode 100644 tools/testing/selftests/bpf/progs/multi_uprobe.c
