This 3 patches demonstrate how to attach BPF programs on uprobe events. They are based on '[RFC PATCH v8 00/49] perf tools: filtering events using eBPF programs'.
The first patch fix a bug in perf probe. The second patch is a kernel side patch, which minimic procedures for kprobe events processing on uprobe events. The final patch improve BPF object section name to allow perf probing at uprobe string. With this 3 patches perf now can connect user space events and kernel space events with eBPF maps. I believe some useful things could be done.
