selftests/bpf: Add stacktrace ips test for fentry/fexit

2026-01-30T21:40:08+00:00

Adding test that attaches fentry/fexitand verifies the ORC stacktrace matches expected functions. The test is only for ORC unwinder to keep it simple. Signed-off-by: Jiri Olsa Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20260126211837.472802-6-jolsa@kernel.org

selftests/bpf: Add stacktrace ips test for kprobe/kretprobe

selftests/bpf: Add stacktrace ips test for raw_tp

2025-11-06T01:05:19+00:00

Adding test that verifies we get expected initial 2 entries from stacktrace for rawtp probe via ORC unwind. Signed-off-by: Jiri Olsa Link: https://lore.kernel.org/r/20251104215405.168643-5-jolsa@kernel.org Signed-off-by: Alexei Starovoitov Acked-by: Steven Rostedt (Google)

selftests/bpf: Add stacktrace ips test for kprobe_multi/kretprobe_multi

2025-11-06T01:05:19+00:00

Adding test that attaches kprobe/kretprobe multi and verifies the ORC stacktrace matches expected functions. Adding bpf_testmod_stacktrace_test function to bpf_testmod kernel module which is called through several functions so we get reliable call path for stacktrace. The test is only for ORC unwinder to keep it simple.
