hi, I'm getting no stacktrace from bpf program attached on kretprobe.multi probe (which means on top of return fprobe) on x86.
I think we need some kind of treatment we do for rethook, AFAICS the ORC unwind stops on return_to_handler, because the stack and the function itself are not adjusted for unwind_recover_ret_addr call If it's any help I pushed the bpf/selftest for that in here: https://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git/log/?h=stacktrace_test just execute: # test_progs -t stacktrace_map/kretprobe_multi thanks, jirka
