From: Yuan CHen <chenyuan@kylinos.cn> 1. **Refactor kernel config parsing** - Moves duplicate config file handling from feature.c to common.c - Keeps all existing functionality while enabling code reuse 2. **Add CET-aware symbol matching** - Adjusts kprobe hook detection for x86_64 CET (endbr32/64 prefixes) - Matches symbols at both original and CET-adjusted addresses Changed in PATCH v4: * Refactor repeated code into a function. * Add detection for the x86 architecture. Changed int PATH v5: * Remove detection for the x86 architecture. Changed in PATCH v6: * Add new helper patch (1/2) to refactor kernel config reading * Use the new read_kernel_config() in CET symbol matching (2/2) to check CONFIG_X86_KERNEL_IBT Changed in PATCH v7: * Display actual kprobe attachment addresses instead of symbol addresses Yuan Chen (2): bpftool: Refactor kernel config reading into common helper bpftool: Add CET-aware symbol matching for x86_64 architectures tools/bpf/bpftool/common.c | 93 +++++++++++++++++++++++++++++++++++++ tools/bpf/bpftool/feature.c | 86 ++-------------------------------- tools/bpf/bpftool/link.c | 38 ++++++++++++++- tools/bpf/bpftool/main.h | 9 ++++ 4 files changed, 142 insertions(+), 84 deletions(-) -- 2.39.5

Thanks! Yes! Both patches look good to me. For the series: Acked-by: Quentin Monnet <qmo@kernel.org> Thanks for this work
