a ksym BPF iterator would be useful as it would allow more flexible interactions with kernel symbols than are currently supported; it could for example create more efficient map representations for lookup, speed up symbol resolution etc. The idea was initially discussed here [1]. Changes since RFC [2]: - change name of iterator (and associated structures/fields) to "ksym" (Andrii, patches 1, 2) - remove dependency on CONFIG_PROC_FS; it was used for other BPF iterators, and I assumed it was needed because of seq ops but I don't think it is required on digging futher (Andrii, patch 1) [1] https://lore.kernel.org/all/YjRPZj6Z8vuLeEZo@krava/ [2] https://lore.kernel.org/all/1656089118-577-1-git-send-email-alan.maguire@xxxxxxxxxx/ Alan Maguire (2): bpf: add a ksym BPF iterator selftests/bpf: add a ksym iter subtest kernel/kallsyms.c | 89 +++++++++++++++++++++++ tools/testing/selftests/bpf/prog_tests/bpf_iter.c | 16 ++++ tools/testing/selftests/bpf/progs/bpf_iter_ksym.c | 71 ++++++++++++++++++ 3 files changed, 176 insertions(+) create mode 100644 tools/testing/selftests/bpf/progs/bpf_iter_ksym.c -- 1.8.3.1
