From: Menglong Dong <imagedong@xxxxxxxxxxx> By default, libbpf will attach the kprobe/uprobe BPF program in the latest mode that supported by kernel. In this series, we add the support to let users manually attach kprobe/uprobe in legacy/perf/link mode in the 1th patch. And in the 2th patch, we split the testing 'attach_probe' into multi subtests, as Andrii suggested. In the 3th patch, we add the testings for loading kprobe/uprobe in different mode. Changes since v3: - rename eBPF to BPF in the doc - use OPTS_GET() to get the value of 'force_ioctl_attach' - error out on attach mode is not supported - use test_attach_probe_manual__open_and_load() directly Changes since v2: - fix the typo in the 2th patch Changes since v1: - some small changes in the 1th patch, as Andrii suggested - split 'attach_probe' into multi subtests Menglong Dong (3): libbpf: add support to set kprobe/uprobe attach mode selftests/bpf: split test_attach_probe into multi subtests selftests/bpf: add test for legacy/perf kprobe/uprobe attach mode tools/lib/bpf/libbpf.c | 47 ++- tools/lib/bpf/libbpf.h | 31 +- .../selftests/bpf/prog_tests/attach_probe.c | 291 ++++++++++++------ .../bpf/progs/test_attach_kprobe_sleepable.c | 23 ++ .../selftests/bpf/progs/test_attach_probe.c | 35 +-- .../bpf/progs/test_attach_probe_manual.c | 53 ++++ 6 files changed, 347 insertions(+), 133 deletions(-) create mode 100644 tools/testing/selftests/bpf/progs/test_attach_kprobe_sleepable.c create mode 100644 tools/testing/selftests/bpf/progs/test_attach_probe_manual.c -- 2.39.0
