From: Menglong Dong <[email protected]>
By default, libbpf will attach the kprobe/uprobe eBPF 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 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
