[PATCH bpf-next 0/5] bpf: make tracing program support multi-attach

by Menglong Dong

For now, the BPF program of type BPF_PROG_TYPE_TRACING is not allowed to be attached to multiple hooks, and we have to create a BPF program for each kernel function, for which we want to trace, even through all the program have the same (or similar) logic. This can consume extra memory, and make the program loading slow if we have plenty of kernel function to trace. In the commit 4a1e7c0c63e0 ("bpf: Support attaching freplace programs to multiple attach points"), the freplace BPF program is made to support attach to multiple attach points. And in this series, we extend it to fentry/fexit/raw_tp/... In the 1st patch, we add the support to record index of the accessed function args of the target for tracing program. Meanwhile, we add the function btf_check_func_part_match() to compare the accessed function args of two function prototype. This function will be used in the next commit. In the 2nd patch, we do some adjust to bpf_tracing_prog_attach() to make it support multiple attaching. In the 3rd patch, we allow to set bpf cookie in bpf_link_create() even if target_btf_id is set, as we are allowed to attach the tracing program to new target. In the 4th patch, we introduce the function libbpf_find_kernel_btf_id() to libbpf to find the btf type id of the kernel function, and this function will be used in the next commit. In the 5th patch, we add the testcases for this series. Menglong Dong (5): bpf: tracing: add support to record and check the accessed args bpf: tracing: support to attach program to multi hooks libbpf: allow to set coookie when target_btf_id is set in bpf_link_create libbpf: add the function libbpf_find_kernel_btf_id() selftests/bpf: add test cases for multiple attach of tracing program include/linux/bpf.h | 6 + include/uapi/linux/bpf.h | 1 + kernel/bpf/btf.c | 121 ++++++++++++++ kernel/bpf/syscall.c | 118 +++++++++++--- tools/lib/bpf/bpf.c | 17 +- tools/lib/bpf/libbpf.c | 83 ++++++++++ tools/lib/bpf/libbpf.h | 3 + tools/lib/bpf/libbpf.map | 1 + .../selftests/bpf/bpf_testmod/bpf_testmod.c | 49 ++++++ .../bpf/prog_tests/tracing_multi_attach.c | 153 ++++++++++++++++++ .../selftests/bpf/progs/tracing_multi_test.c | 66 ++++++++ 11 files changed, 583 insertions(+), 35 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/tracing_multi_attach.c create mode 100644 tools/testing/selftests/bpf/progs/tracing_multi_test.c -- 2.39.2
