Now that kernel provides a new available_filter_functions_addrs file which can help us avoid the need to cross-validate available_filter_functions and kallsyms, we can improve efficiency of multi-attach kprobes. For example, on my device, the sample program [1] of start time: $ sudo ./funccount "tcp_*" before after 1.2s 1.0s [1]: https://github.com/JackieLiu1/ketones/tree/master/src/funccount Signed-off-by: Jackie Liu <liuyun01@kylinos.cn> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20230705091209.3803873-2-liu.yun@linux.dev |
