to get the information about eBPF maps ◦ For the current use-case in LoxiLB, we just need to hook entry-points of BPF_MAP_TYPE_HASH. ◦ Hook into below kernel functions and bpf syscalls ▪ htab_map_update_elem() ▪ htab_map_delete_elem() ▪ htab_map_lookup_and_delete_elem() ▪ bpf_map_update_value() ▪ array_map_update_elem() • This method is inspired by the following proof-of-concept example, which uses eBPF to monitor changes to eBPF maps from user and kernel programs. ◦ https://github.com/CrowdStrike/bpfmon-example
